Abstract
Flights Unmanned Aerial Vehicle (UAV) really require altitude position. The altitude position of the UAV is used to measure the distance between the UAV when flying with ground. In UAV system are there are two modes of altitude position, absolute height and relative height. In previous research, precision farming uses unmanned aerial vehicles for foliar farming. The research has recommended the best spraying at an altitude of 1.5 meters of plants, but there are problems that UAVs are difficult to maintain a stable height of terrain in agricultural lands by plants. This research will optimize the height of UAV for foliar fertilizer using ultrasonic sensors. UAVs for foliar fertilizer use low flights because they have to be a few meters above the agricultural land. The ultrasonic sensor works well at a distance of 24 cm to 700 cm above the terrain, so it can be used as a sensor in the UAV for foliar fertilizer. The agricultural land used in this research is corn plant in politeknik negeri jember area. The process of this research is by building a UAV without carrying the load of foliar fertilizer. The results of altitude visualization graph show that experiments with ultrasonic sensors produce smoother graphs. Ultrasonic sensor data produces waves with a lot of noise, this can be caused by ultrasonic waves emitted bouncing with the leaves of corn plants.

Abstract
Ant sugar is a powdered version of brown sugar and is often referred to as crystal sugar. It is called ant sugar because the shape of this sugar resembles that of ants nesting on the ground. The basic ingredients for making ant sugar are palm juice from coconut and palm trees (palm). In this study, the maximum temperature regulation is 140 oC and the pressure is 2 atm. The materials used in this study were coconut and sugar cane juice produced by farmers in Kokap Wates, Kulon Progo Regency. In the manufacture of ant sugar in the evaporation process the temperature of the material increases with increasing winding temperature and over time. In the process of fresh neera evaporation, the value of heat transfer coefficient ranges between 20-22 (W / m2.oC). This shows that when the initial cooking for this concentration is needed more than 20 Watts to heat the material by 1 oC for an area of ​​1 m2 of material. The value of heat transfer coefficient of turmeric neera beetween 17 - 25 (W / m2.oC).

Abstract
Soybean is an important plant because of its role as a source of vegetable protein and as an industrial raw material. National soybean production is still low so that every year imports need to be large enough to meet national needs. National soybean production in 2014 amounted to 892.60 thousand tons while soybean production in Java reached 566.30 thousand tons whereas 329,461 tons/year came from East Java or 42.43% with productivity ranging from 1.3-1.5 tons/hectare. National soybean productivity has only reached 1.2 tons per hectare to date. National soybean needs to reach 2.4 million tons each year while farmers- production is about 850 thousand tons or about 65% of the needs. As the result, the remaining 1.55 million tons is imported from America. Candidates for new superior varieties, which are G-1, G-2, G-3, G-4, G-5, UNEJ-1 and UNEJ-2 have a potential yield of 2.5 tons/hectare and are of early maturity (pod mature age at 73-76 days) and have resistance to the main disease of soybeans, leaf rust. It is expected that these lines can have a stake in achieving sustainable food security. The study was conducted in April to November 2018 in five soybean production centrals in East Java, namely the experimental plant Research Institute for Beans and Tubers (BALITKABI) in Genteng-Banyuwangi, Muneng-Probolinggo, Ngale-Ngawi, Kendalpayak-Malang, as well as Experimental Garden of Jember State Polytechnic. The experimental design used for each location was randomized block design with ten treatments (genotypes) and three replications. The size of each plot (unit) of the experiment was 2.8 m x 4.5 m or around 12.6 m2 (used by the National Soybean Consortium). The distance between rows was 40 cm and inside the rows was 15 cm. Each hole was filled with three seeds, and after growing, two healthy plants were remained. To find out the interaction between the genotypes and the environment, analysis with a randomized group design was used. Next, the stability was analysis by the Eberhart and Russel method. The result of stability analysis showed that genotypes G-1, G-2, G-3, G-4, G-5, and UNEJ-1 were stabile in five locations, whereas UNEJ-2, Malabar and Ringgit turned out to be unstable.

Abstract
Black rice is a local variety that has advantages and disadvantages. This rice has a high anthocyanin content. However, it has a long life span, high plant habitus, and low yield potential. Productivity improvement of black rice can be done through crossing. The purpose of crossing between two having certain superiority is to assemble superior cultivars and proceed with selection. The effectiveness and efficiency of selection is determined, among others, by the value of heritability and genetic gain. This study aims to determine the genetic gain and the estimated value of heritability of the agronomic characters of F2 generation resulting from crosses between local black rice with several superior varieties of white rice. The research was carried out in the Jember State Polytechnic seed production field, from May to November 2019. This study was conducted using experimental design without replication. The estimated genetic parameters are broad-sense heritability and the genetic gain. The seeds used were F2 generation from the crossing of Arum, BSM, Sertani 9, Cidenuk and Cimelati varieties with local black rice. The observed characters include qualitative and quantitative characters. The expected output target of this research is to obtain one or more lines of hope from crossing results that can be developed.

Abstract
The constraints of vanilla development in conventional vegetative propagation are the presence of Fusarium wilt disease and the limitations of the parent plant as cuttings so that vanilla is developed through micro propagation techniques. The ability of the explants to regenerate and differentiate to form buds in vitro is excessive need to be controlled through cytokine regulation in an effort to get the same vanilla seedlings as parent, healthy and uniform. The objectives of this research are: 1) developing vanilla seedlings through multiplication of shoots by modifying BAP and Kinetin in vitro and 2) obtaining vanilla seeds through uniform, healthy and not attacked by plant disease pests through micro propagation techniques. The study was conducted in the Jember State Polytechnic Network Culture laboratory using a factorial Complete Randomized Design (CRD). Factor 1 is BAP concentration that is 0, 1, 2, 3, 4 ppm and factor 2 is Kinetin concentration which is 0, 1, 2 ppm. Further data analysis used Duncans average difference test of 5% or 1%. The parameters observed in this study were: 1) the budding speed, 2) the number of shoots, 3) the length of shoots, 4) the wet weight of shoots and 5) the development of explants. Achievement of the expected results in this study has a value of Technological Adequacy Level (TKT) 5 which is a picture of validation of cytokine modifications that effectively produce multiplication of vanilla shoots so that the same vanilla seedlings are obtained as the parent, uniform, healthy.

Abstract
Marine sponges represent an important source of bioactive molecules with antibiotic, anticancer, antimalarial, antiaging and anti-HIV activities, to name but a few. However the scarcity of bioactive compounds found in sponges remains a bottleneck in marine drug discovery program, hampering research and development as well as posing a serious threat to marine environment due to an excessive harvest of marine sponges. To tackle the supply and environmental issues, we focus our study on in situ cultivation of 15 sponges from Enepahembang Tahuna, North Sulawesi, Indonesia. The sponges were individually placed on a concrete substrate installed on a PVC (Polyvinyl chloride) module and monitored periodically for 12 months. Cultivation efficiency was evaluated by growth rate, survival rate and antibiotic activity particularly for antimicrobially active sponges. While the total survival rate was 67%, growth rate varied between 18% and 97% with Clathria reinwardti, Acanthostrongylophora ingens, Asteropus sarassinorum showing the highest growth rate. Although they were inactive against our test bacteria, C.renewardti has been known for its ability to biocumulate heavy metal, A. Sarassinorum as the source of the glycosides with antitumor, antifungal and/or antiprotozoan activities dan A. ingens as the antimalarial manzamine producer. In addition, antimicrobial evaluation revealed a striking similarity of antimicrobial profiles between the cultivated and wild sponges. Together, they suggest the importance of in situ mariculture for supplying bioactive compounds and for implementing enviromentally friendly drug discovery program.

Abstract
The aim of this study was to determine the response of the growth of internode explants and leaves of Stevia (Stevia Rebaudiana Bertoni), which were cultured at several BAP concentrations. This study was designed using a non Factorial Complete Randomized Design that is by testing the internode and leaf explants at 3 different BAP concentration levels of 2, 3 and 4 ppm and will be repeated 10 times. The parameters observed related to callus growth include: emergence, type, color and percentage of callus formation. In addition, observations were also made on the parameters of bud growth including the appearance of shoots, number and length of shoots. The results of this study indicate that 100% of leaf and internode explants are able to form callus. The color of the callus explants on average leaves are yellowish green while the internode explants are yellowish white and all have compact textures. In shoot growth parameters, only internode explants were able to grow shoots while leaf explants were not. The emergence of shoots (3 DAP), number of shoots (8.70), and shoot length (2.81cm) were produced by MS media with the addition of 3ppm BAP.

Abstract
Aceh-s patchouli is one of the superior local commodities, and its growth and yield could be improved in various means. One way to increase the patchouli production can be done by using bio-fertilizer mycorrhizal local strain. The purpose of this research was to study effect of bio-fertilizer mycorrhizal local specific strain on the growth and yield of patchouli in Entisols. The research was arranged by a non-factorial randomized block design with three replications. The investigated factor was the bio-fertilizer mycorrhizal from local specific strain with four levels, i.e. M0 (without mycorrhizae), M1 (Glomus mosseae), M2 (Gigaspora sp) and M3 (Mixing between Glomus mosseae and Gigaspora sp). The variety of patchouli used in this study was the Tapak Tuan variety. The observed parameters were plant height and stem diameter of patchouli at 45, 60 days after planting; additionally the parameter of patchouli yields consist of number of leaves, number of branches and weight of leaves were observed at 90 days after planting, and root colonization by mycorrhizae. The results showed that mixed mycorrhizal strains between Glomus mosseae + Gigaspora sp contributed to the best marks for increasing growth and yield of patchouli in Entisols. The similar trend result was also found in the root colonization by mycorrhizae. The strain of mycorrhizal of Gigaspora sp application was not effective for increasing the growth and yield of Aceh-s patchouli in Entisols.

Abstract
Harvested oyster mushrooms with high moisture content are easily damaged by enzyme and microorganism. Drying the mushroom into flour using sun drying or artificial dryer can extend the storage time. Rotary vacuum dryer, an artificial dryer, works on vacuum conditions with automatic material reversal technology. The vacuum conditions can reduce boiling point and minimize the nutrition damage. The purpose of this study is to compare the physical and chemical characteristics of oyster mushroom flour produced by rotary vacuum dryer and sun drying. Rotary vacuum dryer works at 60 o C for 8 hours while sun drying requires 6 hours for 4 days. Next, 80 mesh hammer mill is used to grind the dried oyster mushroom. The process includes physical and chemical test analysis with the statistical results followed by t test to understand the two treatments average differences. The results show that all chemical characteristics: moisture content, protein, ash, dietary fiber, produced by rotary vacuum dryer is not significantly different from sun drying. The physical characteristic: color (lightness) and the water activity are not significantly different but the water holding capacity and bulk density are significantly different.

Abstract
Acclimatization is a critical point for the success of tissue culture propagation. In this phase, in addition to maintaining the condition of the growing environment, accuracy of media composition is required. This study aims to determine the growth response of the Vanda orchid plantlet (Vanda sanderiana) acclimatization phase to the dose of guano and mycorrhizal fertilizers. The design used in this study was a factorial Randomized Block Design (RBD) with 2 factors. The first factor is the dose of guano fertilizer (without guano, 4g/plant and 8 g/plant), the second factor is mycorrhizal dose (without mycorrhizal, 10 g/plant and 20 g/plant). Growth observation variables include number of leaves, leaf length, leaf width and life percentage. The experimental results were analyzed using Analysis of Variace and followed by 1% BNJ test. The results showed that the interaction of the two treatment factors did not significantly affect all parameters. Conclusions guano and mycorrhizal fertilizers are not needed in the acclimatization phase of the Vanda orchid plantlet.

Abstract
Breadfruit is recognized as a plant with the potential to be cultivated as an alternative staple food due to its high starch content and envisioned as a solution to mitigate hunger. The plant bears abundant fruits throughout the year with its productivity is comparable to other staple crops and thrives well in countries where the poor population is high. Breadfruit however, exudes copious amount of latex upon harvesting and the stained epicarp often perceived as low in quality. Standardized methods of harvesting in plantations include a stage of latex draining by inverting the fruit for several hours. The latex will be drained to the ground and considered as an agricultural waste with no current commercial application. Despite being considered as a nuisance, plant latex is rich in proteases functioned as a form of protection against pathogenic attacks. In the effort to identify its potential, the breadfruit latex protease was purified to an apparent homogeneity and its optimal conditions were determined. The stability of the protease was investigated and thermodynamic parameters were estimated in this research. Therefore, these analyses had revealed that breadfruit latex consists of protease with highly stable properties, potentially developed as an alternative commercial protease.

Abstract
Vanda is one type of orchid that has the potential to be developed because it has a variety of shapes and colors. The aim of this research is to find out the right combination of acclimation planting media and humic acid for the growth of hybrid Vanda orchids (Vanda sanderiana). Experiments using factorial Randomized Block Design (RCBD). The first factor is the planting media (zeolite, fern roots, and bagasse) and the second factor is the concentration of humic acid (0 mg / L, 50 mg / L, and 100 mg / L). The results showed that the interaction between the treatment types of planting media and some levels of humic acid concentration showed no significant effect on the percentage of seedling life and on plant growth parameters (height and number of leaves), but significantly different in plant height on the planting media factor. The best growing media is zeolite stone

Abstract
The low production of kopyor coconuts is caused by kopyor-producing coconut plants that only rely on kopyor-bearing coconut trees that have heterozygot genetic constitution (Kk) and are grown from normal phenotypic coconut seeds. Kopyor fruit cannot be grown naturally. One alternative to get true to type kopyor seeds is by embryo culture. Development of reliable clone propagation such as somatic embryogenesis will quickly provide embryos for kopyor. From one kopyor em-bryo that is produced will get many somatic embryos which can then become kopyor coconut seeds. The aim of this research is getting an effective method to produce true to type kopyor seeds and knowing the influence of 2,4-D with or withaout TDZ in inducing callus to produce somatic embryos. This research was carried out in the Lampung State Polytechnic laboratory using a factorial. Factor 1 is 2,4-D concentration 0, 2,5, 5, 7.5, and 10 mg/l with or without the addition of 0.5 mg/l. Further data analysis using the 5% LSD test. The parameters observed in this study were: 1) Percentage of explants callus 2) Callus diameter, 3) Callus weight. The results showed that Increasing concentrations of 2,4-D and 7.5 mg/l can increase the percentage of embryogenic callus, callus diameter, and weighing callus. The addition of TDZ concentration of 0.5 to the medium 2,4-D resulted in a decrease in the percentage of embryogenic callus, callus diameter is narrower and lower weight on embryonic callus kopyor coconut. The concentration of 2,4-D best to induce callus on embryo kopyor is 7.5 mg/l.

Abstract
Land is one of the basic needs in agricultural cultivation. Considering the vast land area of the coast, there needs to be an accurate thought in utilizing the land area of the coast for an alternative farming business with all the consequences so that its limitations can be overcome. Puger District is one of the districts that has been central to the development of horticultural crops since 15 years ago by utilizing sand in the coastal areas. The problem of chili cultivation in puger is still not optimal because of some problems such as plant growth that is not optimal because it is not supported by adequate nutrition and sufficient water. Therefore, there is a need for technological applications in increasing soil fertility in sand fields in order to optimize agricultural production of horticultural commodities, including by providing organic material, zeolite sand and sugarcane stem compost. The purpose of this research is to get the best dose of organic fertilizer, zeolite and sugarcane compost in improving water retention, and cation exchange capacity and chilli growth in Puger District sand and to get the best interaction dose between organic fertilizer, zeolite and sugarcane compost. This research activity will be carried out from May to November 2018. The research was conducted at the Green House Laboratory of Plants and Bioscience - POLIJE, Jember East Java at an altitude of 90 m above sea level. The design that will be used is the design of RAK with 3 factors. The first factor is the dose of organic fertilizer with a level of 20 tons ha-1 and 40 tons ha-1, the second factor is the dose of zeolite with a level of 20 tons ha-1 and 40 tons ha-1 and the third factor is the compost dose of sugarcane stems with a level of 20 tons ha-1 and 40 tons ha-1. The total combination of treatments amounted to 8 and repeated 3 times with each unit consisting of 4 plant pots so that a total of 96 unit plant pots. Analysis of the experimental results includes physical analysis of the soil such as specific gravity, water retention, freezing content, field capacity, and porosity.

Abstract
Soybean is one of important crops in Indonesia because of its role as a source of vegetable protein and it is used as an industrial raw material. Nonetheless, national soybean production is low and cannot keep up with the need. In 2018 alone national production was around 980 thousand tons, whereas the national need for soybeans is around 3 million tons / year. Hence, large amount of import is required to meet national needs every year. This study aims to assemble new high yielding soybean varieties, which have high yield (≥3 ton/ha), early maturity (harvest age ≤76 days), large seed size (>15 g) and have moderate resistance to major soybean disease, the leaf rust, caused by pathogen Phakopsora pachyrhizi. In the previous research, soybean genotypes which fit to the criteria above have been obtained, namely ‘Polije-4- and ‘Polije-5-. However, these genotypes have a major drawback which is the small size of the seed (around 13 g/100 seeds). This drawback can be repaired by using the recurrent backcross method with ‘Ryokko- edamame soybean as the donor parent, which has a distinctly large seed size around 35 g/100 seeds. In the current research, this backcross method between ‘Polije-4- and ‘Ryokko-, as well as ‘Polije-5- and ‘Ryokko- was conducted and resulted in the increase of yield (>20 g/plant) and seed size (>15 g/100 seeds), but still maintaining the early harvest age (≤ 76 days).
