Abstract
The Industrial Revolution 4.0, in addition to the potential to overhaul the industry, also changed various aspects of human life. Almost all nations have included this movement on their national agenda, as a way to increase competitiveness in the global market arena. 4IR includes a variety of advanced technologies, such as artificial intelligence (AI), Internet of Things (IoT), wearables, sophisticated robotics, and 3D printing. The five main sectors that will be Indonesias focus for the initial adoption of these technologies are food and beverages, textiles and clothing, automotive, chemical and electronics. Indonesias abundant agricultural resources are supporting the food and beverage sector so that they have great growth potential, and also as one of the capital to build competitive advantage in the production of biochemical products. According to the Law of the Republic of Indonesia number 16 of 2006, agriculture which includes food crops, horticulture, plantations, and animal husbandry is all activities that include upstream business, farming, agro-industry, marketing, and supporting services for the management of biological natural resources in the agroecosystem, which appropriate and sustainable, with the help of technology, capital, labor, and management to get the maximum benefit for the welfare of society. Horticulture is an art, technology, science, and business for planting and utilizing garden plants and plantations. Efforts to meet the needs of consumers and the community must meet the requirements for evaluating the quantity, quality and continuity of the product. The low productivity of horticulture is caused by problems such as scattered locations, small and inefficient business scale, policies and regulations in the banking, transportation and export and import sectors that have not fully supported national horticultural agribusiness actors. Horticulture business has great potential. Horticultural products need to be encouraged in order to support increased exports. One effort that can be done is to maximize processed fruits and vegetables, with the main objective of reducing dependence on imports of raw materials for agricultural products so as to increase efficiency throughout the industrial value chain through the application of Industry 4.0.

Abstract
Rice cultivation in Java has been practiced for centuries. The long and complicated practices undoubtedly had given birth to synergistic cultivating traditions between farmers and their environment. The drastic and revolutive changes happened in the second half of the twentieth century. Introduction of external synthetic inputs such as fertilizers and pesticides, which was first thought as very helpful in increasing yield and production, is right now reconsidered as negatively affecting rice agroecosystem as a whole. Those inputs inhibited and even destroy natural agroecosystem services. The proofs came from rice herbivore population increase, which happened several times during these changing times. The right practices in coping with rice herbivore or diseases should have been made available. To emphasize the role of ecosystem services, we tried to investigate whether ecosystem basic rules had been violated, and to find out, if the ecosystem services were improved, whether they will help maintain ecosystem balance. Therefore we design experiments to know how far the rice cultivation practices have been affected by the change in ecosystem services, especially in preventing and controlling biological disturbances. First, we tried to know whether mono-culture practices might be improved by using different rice varieties and mixed them prior to planting. Secondly, we practiced crop rotation by interfering continuous all year round rice planting by introducing dry land crops such as corn during the dry season, although the irrigation water was available. And third, we planted refugias around the rice planting area where the refugias were never before planted in the area. All experiments were quantitatively analyzed, and compared to the traditional or conventional practice done by the farmers. The result shows that these practices more or less improved the conventional rice agroecosystem. Mixing varieties resulted in more preferable rice production in term of performance, including taste. The interference of dry land crop, i.e. corn, invite rat, a more destructive herbivore. The planting of refugias increase the number of beneficial arthropod although an ecological equilibrium is still yet to be observed. The adjustment of these practices to the rice environment had not yet commonly done, since what is commonly known as sustainable agriculture was not intensively encouraged. The rice production system is still based on maximum yields and the achievement of self-supporting regions. Understanding of proper practices to ensure the sustainability of rice cultivation should be disseminated among stakeholders.

Abstract
Introduction. The previous investigation was reported in an area with mental retardation due to iodine deficiency disorders (IDD) in Ponorogo. Lack of environment iodine and water contamination of heavy metal need to describe related to IDD in Ponorogo. This contamination caused the risk of inhibition of nutrient intake in exposed plants. Objective. The aim of study was to investigate iodine deficiency disorders, blocking agent, ferritin status and goitrogenic consumption in a peripheral endemic area of IDD area in Ponorogo. Method. This was a cross-sectional study that was conducted in Dayakan and Watubonang Village. Ponorogo. Household that had childbearing women age (CBW), school-aged children 9-11 years old (SAC) and children under five (CUF) were selected as sample. The number of samples in both areas was 118 CBW; 124 SAC, and 123 CUF. About 29 soil and 87 water samples were taken to measure iodine and heavy metal such as: mercury (Hg) and lead (Pb) concentration. Iodine status was determined by median urinary iodine concentration of casual urine sample that measured via spectrofotometry method. Thyroid function diagnosis was carried out through various of test: Thyroid Stimulating Hormone (TSH) and free-Tetraiodothyronine (fT4) by Enzyme Linked Immunosorbent Assay (ELISA). Ferritin contents were measured by the ELISA method. Goitrogenic consumption through semi-quantitative food frequency interviews. Results. Median Urinary Iodine Concentraion (UIC) of CBW and SAC were 105 and 121.5ug/L, respectively. Overall mean of iodine concentration in soil and water were 36.74mg/Kg and 13.6ug/L respectively, Dayakan 25.68mg/Kg and 0.6ug/L, Watubonang 54.83mg and 19.5ug/L. Overall, mean of Hg soil was 96.46mg/kg; Dayakan was 86.32mg/Kg; Watubonang 113.06mg/Kg, and < 1ppb in water both areas. Mean of Pb in soil was 5.81mg/Kg. Dayakan was 4.35mg/Kg; Watubonang 8.19mg/Kg, while not detected in water in both area. Hypothyroid in CBW, SAC and CUF in Dayakan 38.1%; 27.9%; 17.9% and Watubonang 7.3%; 14.3%;17.9%, respectively. Overall goitrogenic consumption in respondent who have hypotiroidism at cassava in 1-3 times/day : 31,5%. Cabbage in 1-3 times / week : 34,8%, green cabbage 1-3 times : 41.2%. Cassava leaves in 1-3 times / week :1,5%. White mustard 1-3 times / week : 27,0%. That respondents with ferritin deficiency were 25.8% in Dayakan Village, and 19.8% in Watubonang Village. The proportion of people with ferritin deficinecy in Dayakan Village was 1.4 times than in Watubonang Village. Conclusion. Overall, thyroid function disorder was found in both areas despite iodine status of population showed in normal value. Dayakan was lower iodine environment status than Watubonang.

Abstract
Breadfruit plant (Artocarpus altilis [Park.] Fosberg) is one species of Moraceae family that is very important as a source of food material. The fruit contains many nutrients that are important for energy sources and health. The propagation technique is only conducted vegetatively because the fruit did not produce seeds. This conservation effort of this species has been carried out by planting breadfruit clones from 14 distribution populations in Indonesia, namely Sleman, Gunungkidul, Cilacap, Banyuwangi, Madura, Sukabumi, Banten, Bali, Mataram, Lampung, Bone, Malino, Sorong and Manokwari. The development of propagation technique needs to be conducted for commercial planting stock production of those clones which is easy to be implemented, does not require high input costs and it is able to produce adequate numbers of planting stocks. Propagation techniques that can be conducted are root cuttings, shoot cuttings and stem cuttings. The average success rate of each technique is 80%, 90% and 80%. The application of these three techniques simultaneously is very efficient and effective to increase the production of breadfruit planting stocks.

Abstract
Farmers on suboptimal land are generally economically disadvantaged and need to be supported by low-cost technology. The study aimed to find out a low input technology package in maize cultivation on suboptimal land in Riau Province. The research was carried out on the tidal agroecosystem overflow type C, around the Mandau River on alluvial land, peat, and alluvial + peat mixture in Siak District. Time of study in March to December 2018. The materials used were hybrid maize varieties such as Nasa 29, Bima Uri 19, and composite maize Bisma and Sukmaraga, Urea, TSP, KCl, farm yard manure, dolomite, locality liquid organic fertilizer (LLOF), grilled ash, biological fertilizers, decomposers, pesticides, herbicides. There are 4 fertilization packages, i.e.: A (high dosage), B (high dosage + LLOF + Grilled ash), C (50% dosage + LLOF + grilled ash), D (low dosage). Experiments were designed using randomized complete block design and repeated three times. To find out whether farming is profitable or not economically, it is analyzed by using Benefit Cost Ratio. The results showed that Nasa 29 and Sukmaraga varieties produced the best average growth and yield for all soil types and fertilizer doses of 4.0 t ha-1 and 3.9 t ha-1 dry seeds, respectively. NASA 29 can produce 6.2 t ha-1 dry seeds in a mixture of peat + alluvial soil even though the dose of chemical fertilizer is reduced by 50%. Reducing the dose of chemical fertilizer can be done to improve the ability of farmers to buy fertilizer depending on the type of soil and the availability of LLOF and grilled ash. Mixture of peat and alluvial is good soil for maize growth if combined with fertilizer package B. Decrease in chemical fertilizer 50% (package C) causes yields to fall to 6.23 t ha-1 and farmers get a profit of Rp 12,418,000 per planting season with B/C 1.9.

Abstract
One obstacle of the chili-s resistance breeding program to anthracnose disease is to find source of resistant gene. In addition, information of inheritance mode and genetic control has not yet been obtained accurately. Line AVPP0207 is a chili genotype that has an resistance gene from accession C chinense (PBC932) transferred into C. annum (IR * 3). Researcher in IVEGRI had succeeded to cross breeding genotype Tanjung-2 with line AVPP0207. The objectives of the study are: (1) to molecularly identify of pathogen isolates Colletotrichum spp from the field ; (2) to individually select of F2 generation that resistance to anthracnose, so that the inheritance mode can be identified. The study was conducted at Indonesian Vegetables Research Institute (IVEGRI) from January to December 2015. The use of specific primers Calnt2 / ITS4 showed a DNA band 490 bp in pathogen isolate 1, while the use of Cclnt / ITS4 showed a DNA band 460 bp in pathogen isolate 2. A total of 15 individually F2 plant numbers (7.07%) were successfully selected as resistant genotypes based on formed lessio diameter on the skin surface fruit (<4 mm). Inheritance mode of F2 chili generation (Tanjung-2 x AVPP0207) for resistance to isolate C. acutatum showed that resistant trait is recessive with incomplete gene action, there is no maternal effect, resistant gene is a major gene with an estimated number is 1.68, and broad-sense heritability (h2bs) is high (0.75).

ABSTRACT PLANT INDIGOFERA AS RAW MATERIALS IN NATURAL BATIK Darban Haryanto (1) Ellen Rosyelina Sasmita (2) darbanharyanto@ymail.com Indigofera plant is one type of plant where the leaves can be used as natural coloring agents for coloring batik cloth which has a prospective future. Yogyakarta as the center of batik most of the batik industry for its coloring material uses chemical dyes. The advantage of this chemical textile dye is that it is inexpensive and has a high stability compared to natural dyes, in addition to the diversity of colors available and the continuity of the guaranteed material so that it is preferred by consumers. But since there is a prohibition on using chemical dyes, especially from azo species in the Netherlands, Japan and Germany, it provides an opportunity to find a substitute for chemical batik colors using natural batik dyes. Dyestuff-producing plants grow in Indonesia, more than 150 types of plants that produce dyes that can be extracted from roots, stems, flowers, bark and others. Among these types of plants producing color is Indigofera. The leaves of this plant can be extracted which can give a blue color. Indigofera plants are relatively easy in their cultivation and do not require fertile land requirements, so that the marginal land of these plants can be cultivated. Indigofera plants are resistant to pruning, so at the age of 4 months the leaves can be utilized to be processed into indigo paste that produces blue color (tom). In its life cycle that can reach 2 years, plants can be taken as many as 6 times pruning. Indigo leaf processing can be done by extracting this plant with the following steps: the leaves are immersed in a soaking tub and then the immersion water is oxidized, the result is a settling paste. This paste is then drained to reduce the water content. Indigo paste produced can be used for natural batik dyes Keywords: batik, natural dyes, Indigofera (1) Lecturer in the Department of Agricultures Agriculture Faculty UPNVY (2) Lecturer of the Department of Agricultures Agriculture Faculty UPNVY Paper presented at the international seminar ICGAI Faculty of Agriculture, Yogyakarta National Development University

Abstract
ABSTRACT The Heap of sugar palm solid waste often become pollutants, potentially used as organic fertilizer by making it compost, because it contains organic matter and high N. Regosol is soil that has poor physical and chemical soil conditions for corn growth because it is constrained by a rough texture and low N. This study aims to determine the effect of compost from sugar palm solid waste on the availability of N Regosol and its uptake by corn. This research is a pot experiment, using Complete Random Design method (CRD) with 5 treatments, each treatment was repeated 3 times. The five treatments are: K0 = Compost at a rate of 0 tons / ha (control), K1 = Compost at a rate of 22.24 tons / ha, K2 = Compost at a rate of 44.48 tons / ha, K3 = Compost at a rate of 66.72 tons / ha and K4 = compost at a rate of 88.96 tons / ha. The results of the study were analyzed with variance at a 5% significance level if there is a real effect further tested by Duncans Multiple Range Test at 5%. The results showed that the application of palm sugar solid waste compost could increase the availability of N Regosol and N sweet corn nutrient uptake. Application of palm sugar solid waste compost at a rate equivalent to 44.48 tons/ha significantly responds to the increased availability of N Regosol and the best absorption of corn.

Abstract
This research aimed to modify a starch obtained from palm oil production waste to produce dextrin through steam explosion (SE). The starch was extracted by an aqueous system followed with sedimentation. The SE process was performed at different temperatures (120, 130, 140, 150 and 160 °C). The dextrin products were analyzed physically and chemically for dextrin solubility, moisture content, ash content, XRD profile, FTIR profile, dextrose equivalent (DE) and molecular weights (MW). The results obtained mentioned that SE process at temperature of 120 oC gave the best characteristics of dextrin which was comparable to commercial dextrin. The dextrin had the best solubility among other products. The XRD profile of the dextrin exhibited the same difractogram patterns with a peak at 2-theta = 19.4 and FTIR profiles with main peaks at wavenumbers 1148, 1077, 994 and 928 cm-1 as CD. Among the temperature treatments, the highest DE value was obtained for SE at temperature of 120 oC (10,33 ± 0.16), which was still less than that of CD (18,46 ± 0.04). This gave the MW of the product 102000 g/mol, higher than MW of CD (44000 g/mol).

Abstract
The potential of sub-optimal land that is tidal land is very wide estimated at 20.13 million ha, spread of in Sumatra, Kalimantan, Papua and Sulawesi, and 9.53 million ha suitable for agriculture. The tidal land is very important resource in order to meet national food needs in line with an increase in population and the rate of conversion of paddy fields, especially in Java. Agriculture aspect cannot possibly meet the needs of a growing population without technology. How is the readiness with the condition of our food, especially our domestic soybeans, facing the era of the industrial revolution 4.0 The Ministry of Agriculture continues to make breakthrough policies and programs to transform traditional agriculture into modern and improve the quality of human resources. Efforts of utilize and optimize tidal land as an area of soybean production development are expected to support the sustainability of national food. This paper presents the contribution of tidal land use to support food sustainability and its strategy from the aspect for the national soybean commodity. If mapped, the position of soybean agro-industry strength in tidal land is in quadrant II, Where, the business area is facing various threats, although the condition of this business still has strength from an internal influence. The threat from external (environmental) factors from the development of soybean commodity is the flood of imported soybeans which are always a competitor to local (domestic) soybeans, so that the comparative advantages of local soybeans is low. And other threats are limited soil fertility in tidal land. There are four strategies, namely: (1) Provision of permanent soybean planting areas; (2) Soil amelioration actions; (3) Increasing national soybean competitiveness; and (4) technology dissemination and promotion of domestic soybean use. Implementation of the strategy is to apply a model of corporate-based soybean agro-industry area. By using this agro-industry model the opportunities for modern agricultural technology use can be implemented.

Abstract
One of the product that produced by SR Silver is aluminum key pendulum. The first production process is smoothing the aluminum key pendulum with sandpapering machine and then polish the is aluminum key pendulum with grinding machine. Both processes are classified as repetitive action, because both hands do repetitive motion forward and backward for seven hours of work without recovery time. In the other hand, there are complaints of pain in some parts of the worker-s body, which are indicative of symptoms musculoskeletal disorders (MSDs). This resesarch is intended to reduce the risk level of MSDs for workers by providing a recovery time schedule for repetitive task. This research uses Occupational Repetitive Action Index Index method to measure the risk level of worker-s MSDs before and after implement recovery time schedule. Recovery time schedule was made by considering the energy consumption of workers (Energy Expenditure). Slot with highest energy consumption will be considered as priority slot to get a recovery time. The results showed that there was a reduction in the risk value of MSDs in both processes. For the smoothing process, in the right hand there was a reduction in risk value from 7,61 (medium risk) to 5,07 (medium risk) andrisk value from 7 (medium risk) to 4,67 (medium risk) forthe left hand. In the polishing processthere was a reduction in risk value from 12,55 (high risk) to 8,37 (medium risk) in the right hand and risk value from 11,01 (high risk) to 7.34 (medium risk) for the left hand.

Abstract
Sweet corn (Zea mays var Saccharata) is the result of a recessive mutation that occurs naturally in genes that control the conversion of sugar into starch in corn endosperm. Three main genes affect the sweetness of corn, namely the sugary gene (su), the sugary enhancer gene (se), and the shrunken gene (sh2). Downy mildew is a major disease in corn and can cause yield losses until 100% if it infects resistance plants at 10-15 days after planting. The purpose of this study was to obtain information on the character of growth, yield components and downy mildew disease resistance on some sweet corn lines in the S-3 generation. The study was conducted on July 2019 until October 2019 in Wedomartani Experimental Garden, Faculty of Agriculture, UPN Veteran Yogyakarta. The seven pure line were used: BFa, BFb, BFc, BFd, BFe, BFf, and BFg by using a Randomized Block Design with 3 Blocks. Planting in each experimental unit consists of 3 rows, each row consisting of 20 plants. The growth properties that were observed is plant height, stem diameter and number of leaves. The yield components that were observed is the number of cob, the length of the cob and the diameter of the cob. The plant disease resistance variables were the number of infected plants, the number of live plants and disease incidence. Data were analyzed by analysis of variance with 5% significance, followed by Duncans multiple range test with a level of 5%. The results showed that there was no difference on all line used. In the yield component the results show that lines that have largest lengths are BFa, BFe, BFf, and BFg. All line have largest diameter of the cobs except BFg. BFc, BFd, BFe, BFb, and BFg have high resistance on corn downy mildew.

Abstract
The existence of local varieties of potatoes for the processed industry in Indonesia is very necessary, most of the raw materials for the potato chip industry are still imported. Even for French fries, one hundred percent is still imported. Selection of 30 potato clones was conducted at the Margahayu Experimental Field (1250 m asl), in Lembang from January to May 2016. It used a completely randomized block design with 3 (three) replications which every plot consisted of 10 plants. The evaluated characters included plant vigor, plant height (cm), stem diameter (mm), tuber weight (g), percentage of consumption tuber (%), yield (ton/ha), specific gravity (Sg), tuber shape, tuber skin color, tuber flesh color and appearance of tuber skin. Analysis of variance showed that all quantitative characters were very significantly different (P <0.01). Clone 15.33 showed the highest tuber yield per plant (831 grams/plant) which was significantly different from the comparable variety of Atlantic (166 grams/plant). The highest percentage of consumption tubers was obtained from clones 15.26 (75.3%) which were significantly higher than comparable varieties (Amabile, Granola, Medians and Atlantic). The result suggested that 2 (two) clones e.g. 15.33 and 15.23 with specific gravity (Sg) higher than 1.067 are potential to be used for industrial potato chips.

Abstract
The aim of this study was to examine the effect of VOC exposure from cigarette smoke on the plant growth regulator (PGR) patterns consisting of Indole Acetic Acid (IAA), Abscisic Acid (ABA), Ethylene, Salicylic Acid (SA) and Jasmonic Acid (JA) so that later it could be screened for some ornamental indoor plants that could be used as a phytoremediator agent. The ornamental plants used are Drimiopsis kirkii, Epipremnum pinnatum, Sanseviera trifasciata, Peperomia obtusifolia variegata and Dieffenbachia seguine. Exposure to plants with cigarette smoke containing formaldehyde as much as 0.1 ppm for 5.5 months then the content of the PGR was observed. The results showed that of the five ornamental plants used, there were two expression patterns of PGR. In D. kirkii and P. obtusiifolia-variegata there has been an increase in IAA, while 3 other species have decreased. Exposure to cigarette smoke decreases ABA in all five species while Ethylene increases. The most interesting discussed in this research is the increase in IAA in D. kirkii was not followed by changes in the expression of SA and JA.

Abstract
Global climate changed increased rice area affected by salinity which decreased rice production and farmer income especially in the coastal area. High yielding rice varieties tolerant to salinity is one of technology component to manage salt affected soil. The study aimed to identify high yielding rice lines adaptive to saline prone area having a high yield potential. A total of seventy seven of genotypes along with four check varieties (Inpari 34, Sidenuk, FL478 and Inpari 43) were tested in saline prone rice area, Eretan, Indramayu on January to April 2018 using randomized completed design with two replications. The thirty lines selected from the yield trial and reevaluated for high yield under normal condition at ICRR research station Sukamandi in WS 2019. The result identified three lines having high grain yield and low salinity tolerance index which were comparable to the best check FL478 and Sidenuk. These two lines were promising lines to be evaluated in advanced yield trial in several different environments.

Abstract
Monggol Village, Saptosari Subdistrict, Gunungkidul Regency is an area that often experiences drought, especially during the dry season, resulting in a lack of clean water for daily needs and for agricultural cultivation. The purpose of this study was to determine the quality of the soil on the plots of land that use PAM (Water Supply Company) water irrigation intensively to realize a food independent village in Monggol Village, Saptosari District, Gunungkidul Regency, Yogyakarta. This research was conducted using descriptive survey methods. Purposive soil sampling, taken at two locations. Location A: land without PAM water irrigation, planted during the rainy season, Location B: land with PAM water irrigation intensively, each location is taken 3 soil samples as replications. Soil quality is determined by calculating the Soil Quality Index using the criteria of Mausbach and Seybold (1998). Soil properties observed were soil texture, volume weight, specific gravity, porosity, actual pH, C-Organic, total N, available P, available K, root depth, and number of microbes. The results showed that the Soil Quality Index on land without PAM water irrigation (Location A) were: location A1 0.58; location A2 0.54; A3 location was 0.73 with an average of 0.62 including good soil quality criteria while the Soil Quality Index on land with PAM water irrigation (location B): location B1 is 0.39; B2 location 0.36; B3 location 0.30 with an average of 0.35 including poor soil quality criteria. Intensive tillage on land with PAM water irrigation causes soil quality to decrease or lower than rainfed land, this indicates the need for the addition of balanced fertilizer on intensively managed land.

ABSTRACT. The demand for potato in the domestic chips industry is very high and most of it is still imported. Therefore a breakthrough is needed to get new superior varieties of processed potato chips that are suitable for industrial raw materials both large, medium and small industries. The purpose of this study was to obtain a new chipping potato variety. The output of this activity is to get a chipping potato variety. The study was conducted in Cikajang, District Garut (1300 m asl). The experimental design was Randomized Complete Block Design (RCBD), number of replications was 4 times, the treatment consisted of six genotypes Spudy Agrihorti, clones 12.20, clones 14.5.1 and three comparative varieties Atlantic, Medians and Granola. Plant population 80 plants / plot. Observations were made on the qualitative character, quantitative character and chemical analysis of potato. The results showed that one superior genotype was Spudy Agrihorti with very high yield potential reaching 40.8 tons / ha higher than comparative varieties of Atlantic (29.4 tons / ha) and Medians (32.3 tons / ha). Spudy Agrihorty also displays supporting data of highly qualified processed quality to be used as raw material for the chips industry. This is indicated by high carbohydrate content of 14.77%, high specific gravity of 1.093 m3 with very low reducing sugar content of 0.03%. The quality results of Spudy agrihorti chips are preferred by consumer respondents because they have a yellow chip color compared to chipping varieties of Atlantic and Medians.

Abstract
Farming is one of the activities that organizes agricultural production facilities and technology in a business that involves the field of agriculture. to obtain maximum production, farmers must be able to combine the factors of production of labor, fertilizer and seeds used. These three factors of production are interrelated with one another in influencing production to produce good and optimal productivity. Agricultural businesses in the District of Jagakarsa are carried out in groups by forming farmer groups. Based on the results of the analysis of nonfinancial aspects, it shows that the cultivation of starfruit goddess with the development through standard operational procedures for starfruit fruit cultivation in Jagakarsa District is feasible to be carried out by farmer groups. The socio-economic-cultural aspects of the goddess starfruit cultivation business have a positive impact where the business is beneficial for the surrounding community. On the environmental aspect, this cultivation business also shows its feasibility because with the existence of starfruit cultivation as a greening the environment and water absorption. Based on the results of financial analysis shows that the cultivation of the goddess starfruit fruit plants provides benefits for fruit plant farmers. The profit of farmers in a year can improve the welfare of starfruit farmers.
