Abstract
Seed vigour evaluation is important as one of seed quality parameters to meet the farmers demand. The direct and indirect methods could be used to test the seed vigour. Even though, the different population cultivar may show a different response when vigour test. Therefore, the accurate method is needed. In this study, we used UNPAD Mutant (one population) and Non-Mutant (two populations) sweetcorn lines to determine the characteristics of vigour among populations after 2 months storage using direct (vigour index and normal dry seedling) and indirect (electrical conductivity) methods. The results showed that there were significant difference among populations (Tukeys test) on electrical conductivity parameter at 0 month and normal seedling dry weight parameter at 2 months after storage. Besides, we found the significant correlation between vigour index and electrical conductivity at 0 month and between normal seedling dry weight and vigour index at 2 months after storage. We assumed that the significant correlation between two parameters in this study due to the significant difference among populations at the time of measurement. These results suggested that among populations have different vigour characteristic. The electrical conductivity and normal dry weight seedling were an important approach to investigate seed vigour.

Abstract
Cassava has been a premier commodity as the raw material for local-s food production. Gunungkidul regency well known as the central production of cassava, thus, become the main reference for the consumers i.e. persons, group, and firms. However, Cassava-s availability has remained a problem as its productivity cannot fulfill the demand of the market. Planting and harvest time are the premier problem as it is remain unclear, especially for local variety at Gunungkidul regency. This research aim to determine the proper time to plant and harvest for Gambyong varietycassava. Factorial experiment method is used in this research, which is arranged by Randomized Complete Block Design (RCBD). This research tested some a set of treatments on the planting times (September, October, November, and December), and the harvest age (four, five, six, seven, eight, and nine month). Each treatment is repeated three times, so that there are 72 treatment units that tested. The research result showed that the cassava planted on the September has growth, development, and tuber yield tend to increased started from 4 - 9 month of harvest age. Whereas, the cassava that planted on October up to December showed growth, development, and tuber yield tend to decreased on all harvest age.

Abstract
Broccoli (Brassica oleraceae) is one of the prospective agricultural products to be developed in Indonesia because it is a source of vitamin A, B complex, C, ascorbic acid, thiamin, riboflavin, calcium, iron and minerals essential for the fulfillment of human nutrition and contains sulforaphane which can prevent cancer, besides it helps digestion, neutralizes acid and does not contain cholesterol. The amount of vitamin content found in broccoli makes the demand for broccoli on the market has increased by 15-20% per year. However, the high demand is not balanced with adequate quality and quantity of production. One of the causes of decreasing the quality and quantity of broccoli production is the use of inorganic fertilizers continuously. Provision of inorganic fertilizers or chemical fertilizers for a long time can cause soil damage in physics, biology, and chemistry. Plant organic waste is the raw material for the fermentation process for soil microbes which is useful for increasing the quantity and quality of crop production and maintaining environmental sustainability. Organic waste that has undergone a fermentation process can be used by plants as liquid organic fertilizer and at the same time can be used by plants as a stimulant to grow. The aim of the study was to examine the relationship between the dose and concentration of fruit organic waste extract to growth and yield of broccoli. The study was carried out on the integrated land of the Faculty of Agriculture-Animal Husbandry of the University of Muhammadiyah Malang from February to May 2018. It is a factorial experiment arranged in a Randomized Block Design and repeated 4 times. The first factor is the concentration of fruit organic waste extract, namely K1: 50 cc /l ; K2: 100 cc /l; K3: 150 cc /l, the second factor is the dosage of fruit organic waste extract, namely: D1: 50 ml /plant; D2: 100 ml /plant. The parameters of observation included plant height, number of leaves, stem diameter, flower diameter, flower weight, wet weight, dry weight. Data were analyzed using Fishers test, then tested using BNJ test 5%. The results showed no interaction between the concentration and dosage of fruit organic waste extract on the growth and production of broccoli plants. There is a positive correlation between each observed variable. The best concentration of fruit organic waste extract is 100 cc/l. The best dose of fruit organic waste extract is 50 ml /plant

Abstract
There are some procedures to advance the quality of papaya; one of which is by sufficing the need of high-quality seeds in proper amount. Using plastic polybag for plant nursery will negatively pollute the environment and is polybagential for resisting the root-s growth. Therefore, organic polybag is claimed as the best solution due to its excellence of not undergoing segregation process during seed plantation. In addition, it also has good drainage and aeration to support the root-s growth. Further, this current research aimed at testing the use of organic polybag for papaya nursery. There were 7 treatments in total with organic polybag as the main highlight. The control variable was organic polybag (PO – with 60% of water hyacinth: 40% banana pseudo stem). Meanwhile, the 7 treatments comprised 59% of water hyacinth: 40% banana pseudo stem: 1% manure [POA – organic polybag with chicken manure; POS – organic polybag with cow manure; POK – organic polybag with goat manure); and POP – organic polybag with manure made of Tithonia diversifolia] and 59% of water hyacinth: 39% banana pseudo stem: 2% combined manure [POAS (chicken + cow manures), POAK (chicken + goat manures), POAP (chicken + Tithonia diversifolia manures)]. The variables under observation consisted of height of plant (cm), number of leaves (blade), diameter of stem (mm), length of root-s penetration (day), dry weight of stem (g), and weight of root (gr). Moreover, the data were analyzed by using F-test, followed by BNJ or Tukey appealing test with 5% of significance and finished by correlational analysis in between variables of observation. The use of organic polybag for papaya nursery resulted in significant effect when it was compared to the control on variables of observation (such as number of leaves, length of root, dry weight of root, and diameter of stem); yet, it was relatively different compared to that of in POP treatment on height variable (from 21 to 28 days after planting), in POA treatment, and in POAK treatment on stem-s diameter variable.

Abstract
Abstract The study aimed to evaluate the administration of water jasmine plants through increasing the capacity of plants as phytoremediators in reducing the waste of intensive culture eel. This study used a completely randomized design with three treatments of water jasmine plant density and repeated 3 times, as treatments were 1.04 g/L (Ep1), 2.08 g/L (Ep2), and 3.13 g/L (Ep3). The initial average eel weight was 8.3 g, with a stocking density of 4 g/L. Culture of eel is carried out in a 50 cm diameter tub and 55 cm high with a recirculation system with water jasmine plants as phytoremediators. Jasmine water is planted in an aquarium measuring 60 cm x 40 cm x 40 cm with a volume of 48 L. A feed paste contain 45.15% protein as much as 4% weight of eel biomass, was given 3 times a day. Culture is carried out for 60 days. The results showed a significant difference in the effect of water jasmine density on nutrient removal efficiency, also performances on the growth of eel and plant. Plants of E. palaefolius (water jasmine) with a density of 2.08 g/L had the highest TAN efficiency removal nutrients, nitrite, nitrate and phosphate compared to density of 1.04 g/L and 3.13 g/L. Nutrient removal efficiency at a density of 2.08 g/L, id est TAN 46.03%; nitrite 49.65%; nitrate 59.62% and phosphate 60.88%, respectively. At a jasmine density of 2.08 g/L produced the highest specific growth rate of eel 0.99% the lowest feed conversion 1.97, and the highest increasing of water jasmine biomass (262.33 g with a daily growth of 4.37 g/day). Thus, it can be concluded that the density of water jasmine 2.08 g/L produces the best nutrient removal efficiency, the growth performance of eel and plant.

Abstract
Gunung Kidul is the centre of cassava production. However, due to its Mediterranean soil type, it is regarded as a non-fertile soil as it was formed from the decay of limestone, has low organic matter, dry texture, brittle, and pH value of neutral to basic. Mycorrhizal inoculation is known to increase plant production, however, the effectivity is affected by the plant variety and mycorrhizal sources. This study aims to understand the interaction between various mycorrhizal sources and three local cassava varieties of Gunung Kidul, specifically on their compatibility, population, mycorrhizal diversity, and their effect on cassava growth. The experiments were conducted based on Completely Randomised Design (CRD) with experimental factors using three treatments in triplicates. The experimental factors included three cassava varieties (Mentega, Kirik, and Ketan) and various sources of mycorrhiza (indigenous Mediteran soil of Gunungkidul, the rhizosphere of pandan plants of Bugel beach, and commercial mycorrhizal inoculant). The results demonstrated that among the interactions of various mycorrhizas with three local cassava varieties of Gunung Kidul, the highest infection was seen from Mentega variety inoculated with indigenous mycorrhiza of the Mediterranean soil of Gunung Kidul (95%). The mycorrhizal population yielded 39-98 spores/100g. Mycorrhizal diversity using indigenous mycorrhiza of Mediteran soil was higher than mycorrhiza of pandan rhizosphere and commercial inoculant, and the dominant mycorrhiza type was of spores belonging to genus Glomus. On the other hand, the indigenous mycorrhiza of Mediteran soil inoculant on various cassava varieties demonstrated similar effect as it resulted in the same number of spores, root length, and plant dry weight; despite the fact that on Kirik variety growth, the significant difference was observed on the plant height, leaf number and fresh plant weight.

Abstract
Economic development can affect many factors, such as agriculture and industry. These two sectors can significantly affect the economic health. Population growth drives the employment opportunity to be increased. Industry become the area that can provide many employments, extend the industry is not easy because the side effect often take agricultural land area for operation. Industry in Daerah Istimewa Yogyakarta also growing like the other places. The land changing from agricultural land area to other functional land is gradually increasing year by year. This study aim to analyze the correlation between the industrial growth and the decreasing of agricultural land. The data from 2001 to 2016 was analyzed to know the correlation. The results show that there are signicantly correlate between industrial growth and the decreasing of agricultural land in Kulonprogo District, Bantul District, Sleman District and Gunung Kidul District which known as food production center in Daerah Istimewa Yogyakarta. For Yogyakarta City which does not have many agricultural land show no correlation between industry growth and the decreasing of agricultural land area. Therefore growing the industry must consider the land area that be used for expansion.

Abstract
In agricultural landscapes, natural habitat play may enhance species diversity or the abundance of natural enemies in arable lands, and thereby suppress pest populations effectively. However, there is a lack of studies in Tropical regions about these interactions. The aim of this study was to investigate the community structure of Hymenoptera parasites at two distances (< 200m and > 400 m) from edges of natural habitat to cucumber fields. This research was carried out in twelve cucumber fields in West Java, Indonesia. Hymenopteran parasites were collected by yellow pan trap and hand picking of parasitized lepidopteran larvae. In total, 19 family and 132 parasitoid species, comprising 19,167 individuals, were collected in our experiments. A number of 56 (43.1%) hymenopteran parasites species found only in cropping with a certain distance away from the natural habitat. Of these, as many as 39 species (69.6%) hymenopteran parasites found in cucumber fields within close natural habitats, while the crop is being of natural habitats found 17 species (13.1%). Moreover, the functional diversity of hymenopteran parasites tends to increase on cropland closed to natural habitat. We conclude that distance of agricultural land to natural habitat affect hymenopteran parasites.

Abstract
Indigofera tinctoria is a source of natural blue indigo color that belongs to Fabaceae family. Natural dyes extracted from plant leaves containing indican compounds. The growth and yield of this plant are determined by the availability of nutrients. The way to improve growth and yield of indigofera is using rhizobium and mycorrhiza. This study evaluated the Indigofera tinctoria growth as the response of mycorrhizae (AM) and rhizobium, nodulation and productivity. Indigofera tinctoria plants were cultivated in the Faculty of Agriculture Greenhouse with a complete randomized block design with two factors. The first factor was the inoculation of Rhizobium sp with 3 levels (0.1 and 2 g per plant). The second factor was mycorrhizal inoculation with 3 levels (0, 5 and 10 g per plant). The results indicated that rhizobium significantly affected plant growth. Rhizobium increased plant height, number of leaves and number of shoots from 2 week after planting (WAP) to 12 WAP. Inoculation of Indigofera tinctoria with AM fungus resulted a significant increase in nodulation. Root growth was longer with mycorrhizal inoculation. In addition, mycorrhizae also enhanced canopy and root biomass at 6 WAP. Mycorrhizal and rhizobium inoculation of indigofera tinctoria plants significantly increased plant growth, number of nodules and biomass. Inoculation doses in this study were linearly correlated with growth, nodulation and results. Thus, the combined inoculation with mycorrhiza and rhizobium showed a synergistic effect. This combination could be applied to improve plant growth.

Abstract
Coconut waste water is very abundant in Indonesia, because Indonesia is one of the worlds largest coconut producers, with a production of 18 million tons per year. Bacterial cellulose (BC) can be produced using coconut water using Acetobacter bacteria. The aim of this study was to investigate the effect of drying temperature on the crystallinity and morphological structure of BC. A. xylinum was grown on coconut water culture medium with addition of sugar (5%), incubation period 7 days at pH 5. The BC were dried using two drying method such as oven at 50oC and 100oC, and room temperature drying without using oven. The drying was conducted until it achieved 2-6% moisture content. The three different temperatures showed different colour of physical appearance of BC, and the room temperature of dried BC showed the best result of colour. It also gave the different properties of BC based on Scanning Electron Microscopy (SEM) method for evaluating its surface morphology and X-Ray Diffraction (XRD) method for its crystallinity. Therefore, the present work proposed the most suitable drying method can be performed based on the end products desired.

Abstract
Apple has high economic value and contains high vitamins. One of the causes of the decline in apple production is plant disturbing organisms. Red scales (Aonidiella aurantii) is one of the most important pests in apple. The losses caused by the scales are causing disruption of production and growth processes, even leading to plant death. The effectiveness of limestone in controlling red scales (Aonidiella aurantii) on apple trees was carried out in the experimental garden of the Indonesian Citrus and Subtropical Fruit Research Institute Jl. Raya Tlekung No.1, Junrejo-Batu City, from March to June 2017. The treatments tested are the limestone concentration of A. 10%, B. 20%, C. 30%, D. 40%, E. 50 %, F. Control. The treatments were arranged using a Randomized Block Design and repeated three times. The test results showed that limestone of E. 50% concentration applied by spraying on the stems of apple trees effectively suppressed the development of red scales population with an average population of 3/10 cm

Abstract
The popularity of purple sweet potato continues to increase from year to year. Natural sweetness, attractive color, and high antioxidant were alleged as the main allurement of its products. Unfortunately, there are some lacks on the nutritional properties of purple sweet potatoes, such as low in protein and lipid. This shortcoming could lead to a serious malnutrition problem if there is no nutritional complement from another source. In this condition, fortification could serve as a strategy that addressed to improve the nutritional value of sweet potato products. As a source of protein and several bioactive compounds, legumes are suitable to be a carrier on the fortification process. This study was aimed to determine the physicochemical characteristics of sweet potato flour fortified with legumes. This study used a completely randomized design with four variation treatments, i.e. without fortification as a control treatment, soybean fortification, mungbean fortification, and cowpea fortification. The data were analyzed using one-way ANOVA with a significance level at 5% and if there were a significant difference between treatments then it will continue with Duncan Multiple Range Test. The results showed that among other legumes, soybean is the most effective carrier on fortification of sweet potato flour. Purple sweet potato flours that were fortified with 10% soybean have the highest nutritional properties, specifically protein (8.65%), lipid (3.02%), and amylose (32.09%). Furthermore, the increasing of protein fraction due to fortification in purple sweet potato, not only reduced the carbohydrate fraction but also generated sweet potato flours becomes darker.

Abstract
Rice has high productivity and is widely utilized by local food producers as raw material for making the fruit. Karak is a dry food product made from rice which is generally processed conventionally with the addition of salt and chemicals in the form of borax as an ingredient. However, given the prohibited use of borax, there are several manufacturers that produce non-conventional, free-of-borax Karak that require high investment and production costs. In order to produce Karak that is safe to be consumed and can be produced in a conventional way, research on the production of borax-free Karak using additional ingredients in the form of STPP (Sodium Tripolyphosphate) as an ingredient is conducted. The purpose of this research is to identify the effects of STPP addition towards the sensory, chemical, physical, and yield characteristics. This study used Complete Randomized Design of one factor, namely the concentration of STPP consisting of 0.5% (K1), 0.6% (K2), and 0.7% (K3) with the comparator in the form of baking soda (Control). The data obtained were analyzed using one way ANOVA method and if there is a real difference, it was followed by Duncans Multiple Range Test (DMRT) test with significance α = 0.05. The results show that the addition of STPP has several effects on the sensory, chemical, physical, and yield characteristics of the Karak produced. The best formula produced by the weighted test is 0.5% STPP (K1) formula. The K1 formula has the most preferred taste, texture, and overalls by the panelists, the lowest moisture content, the highest development power, and also the lowest hardness and the highest yield result.

Abstract
The area of Indonesian rice fields in 2016 reached 8.19 million hectares (ha), an increase of 1.16% from the previous year, this number comprising 4.78 million ha of irrigated rice fields and 3.4 million ha of non-irrigated rice fields. On the other hand agricultural activities also cause climate change due to greenhouse gases (GHG) produced. GHG is a gas contained in the atmosphere, which absorbs and re-emits infrared radiation. This study aims to make a model of the rice productivity system, so as to produce a strategy to mitigate GHG emissions without reducing rice yields. Emissions to be mitigated in this study are CO2 and CH4. The approach is carried out with a dynamics system because it has the characteristics of a complex, non-linear system dynamics, changes in system behavior over time and feedback that describes new information about the state of the rice productivity system, which will then produce further decisions. The results of this study are mitigation strategies for CH4 and CO2 carbon emissions that are modeled using a dynamic system to analyze current conditions and evaluate existing problems so that they can provide alternative problem solving scenarios.
