Abstract
Rice bran is known having bioactive antioxidant compounds that are hydrophilic and lipophilic. Rice bran extraction on hydrophilic bioactive compounds need to be optimized. This study aims to determine the impact of hydrolysis and non-hydrolysis treatments to bran as well as the solvent type on the antioxidant activity of hydrophilic bioactive compounds in bran extract. The study was conducted by varying the treatment of bran extraction to obtain the best hydrophilic extract. Variation in treatments include with or without hydrolyzing rice brans. In addition, there were variations on the solvent type to dissolve the hydrophilic bioactive compounds by using 96% of ethanol and ethyl acetate. Parameters of the observation consist of yield, total phenol and antioxidant activity scavenging free radicals (DPPH). The results showed that the treatment of hydrolyzed and un hydrolyzed rice brans and the solvent type provided a significant difference to the yield, total phenol and antioxidant activity of hydrophilic bioactive compounds from rice bran. The highest yield (1.72%), total phenol (12.37 mg EAG/g) and antioxidant activity (68.74%) were resulted from the bran treatment without hydrolysis and using ethanol as the solvent type. Extraction of hydrophilic bioactive compounds can be done by using a method without hydrolyzing the rice brand and using ethanol as the solvent.

Abstract
Excessive use of chemical fertilizers and long harvest time are problems faced by farmers in cultivation of broccoli (Brassica oleraceae). Excessive use of chemicals has the disadvantage of increasing control costs, increasing the death of non-target organisms and reducing environmental quality. Broccoli plants require essential nutrient requirements for maximum growth and yield. The use of organic fertilizer is one way to increase the growth and yield of broccoli plants, because it does not contain harmful elements (such as heavy metal elements or degerous chemicals) that can pollute the surrounding environment. Broccoli vegetable cultivation in organic farming systems is a way of agricultural cultivation that relies on natural ingredients or inputs without using chemicals. The purpose of this study was to determine the levels of N, P and K nutrient removal on broccoli cultivation of organic, semi-organic and conventional farming systems in Batur village, Getasan district, Semarang Regency. This study uses a Completely Randomized Block Design with 3 treatments, namely organic, semi-organic and conventional farming systems. Each treatment was repeated 5 times in which the local farmers land was repeated. The research method uses survey methods in soil and plant sampling on organic, semi-organic and conventional farming systems of broccoli cultivation with a harvest age of 4. 6, 8 and 10 weeks. Observation of soil analysis properties before the experiment included: soil pH, N-total, C-organic, P-total and P-available, K-total and K-available, CEC soil, Bulk Density, Particle Density of soil and Percentage of total porosity. As plant growth parameters are broccoli plant height and the amount of broccoli leaves while broccoli yields are carried out from the age of 4, 6, 8 and 10 weeks after planting. While the analysis of N, P and K nutrient removal were determined when the plants was reached 10 weeks old. The results of this study showed that the chemical and physical properties of the soil in organic broccoli cultivation were better than in semi-organic and conventional farming systems, which proved that pH, C organic, total N, P-available and K-available were extracted with 25% HCl has a higher value, while the physical properties which are particle density and bulk density has a lower value. It means that the soil structure is crumb and not easily flooded. Growth and production of fresh broccoli at 10 weeks by an organic farming system is better than in semi-organic and conventional farming systems, which is evident from the N and K nutrients removal that they have more highest 38,85% of N and 20,13% of K nutrient uptake, respectivelly and significantly level than in conventional farming system especially in the leaves of broccoli plant.

Abstract
One of the efforts made in increasing rice productivity is through the application of cultivation technology. Agricultural Research and Development Agency as a producer of technological innovation, in 2016 has launched an environmentally friendly rice cultivation technology package namely Jajar Legowo (Jarwo) Super Technology . The objectives of the study are: 1) to find out the production and productivity of lowland rice farming with the application of Jarwo Super technology package, 2) to determine farmers perceptions of Jarwo Super rice technology innovation, and 3) financially analyze rice farming by applying Jarwo Super technology package in Gorontalo . The activity of applying the agricultural innovation was carried out in the Kawa 1 Farmers Group in Hutabohu Village, West Limboto District, Gorontalo Regency, Gorontalo Province. The total area of Demfarm assesses the application of the Jarwo Super rice technology innovation, which is 15 hectares by involving 15 cooperative farmers. This applied review activity is carried out in March to July 2018. The method of implementing the applied review is carried out by comparing the introduction of technology from the Agency for Agricultural Research (as treatment) with existing technology commonly practiced by farmers. The superior varieties of lowland rice used were Inpari 30, Inpari 31, Inpari 40, Cigeulis, Mekongga, and IR 64. The results of the study revealed that rice productivity with the application of the jarwo super technology package from highest to lowest respectively was the jarwo super package Inpari 40 ( 8.19 tons / ha), jarwo super Inpari 30 (7.73 tons / ha), super full organic IR 64 jarwo (6.09 tons / ha), Jarwo super Cigeulis (6.05 tons / ha), Jarwo super Inpari 31 (4.41 tons / ha) . The average rice productivity with the application of the super jarwo package of 6.49 tons / ha, is higher than the productivity of rice with existing farmers technology (3.53 tons / ha), so that the application of the jarwo super rice technology package can increase rice productivity by 84 percent from existing technology the farmer. The average farmers perception of jarwo super rice technology innovation shows that jarwo super technology increases production, income, is easy to implement, and farmers are interested in implementing it again. The results of the financial analysis of farming shows that rice farming with the application of the jarwo super technology package increases the R / C ratio compared to the existing farmer farming.

Abstract
White grub, Lepidiota stigma is one of destructive pest of sugarcane in Indonesia. The fungus Metarhizium anisopliae is known as pathogen of this pest. The research aims to determine the survival of L. stigma larvae on soil treated with the fungus M. anisopliae. Fungi reproduced in the laboratory using sterile corn media for 30 days, then harvested and treated in sandy loam soil with a concentration series 105-108 spores / gram. At each concentration series tested 10 larvae of the second instar of L. stigma with three replications. During the larval rearing used fresh carrots as feed and feed replacement is done each time the same week of observation. The results showed that the fungus M. anisopliae is able to inhibit the development of the second instar larvae of L. stigma to turn to the third instar, pupa and into adulthood. Highest inhibition occurs when third instar larvae phase does not eat, and it ranged between 46-100%, whereas inhibition when entering the third instar stadia ranged between 16-56%. Treatment of M. anisopliae in soil with concentrations of 108 spores / gram gave the highest inhibition reached 100% in third instar larvae of L. stigma, while the treatment of 105, 106 and 107 spores / gram still managed to hold its development of larvae reaching prepupa. Treatment of the fungus at a concentration of 105 and 106 spores / gram is capable of causing mortality of L. stigma larvae reached 93.33% and 96.67%, while the treatment of 107-108 spores / gram already caused 100% larvae failing to reach adult life.

Abstract
ABSTRACT The aims of this study is to assess (1) the multidimensional sustainability index and status of paddy farming system, (2) the sustainability index and status of each dimension (ecology, economy, socio-cultural, technological and institutional) of paddy, and (3) sensitive attributes that are affecting the sustainability of the paddy farming system. Primary data used in this study, obtained from interviewing farmers, extension agents, Subang Agricultural Agency and related stakeholders. The method of selecting samples was done purposively by selecting one village in Subang and Karawang which is the center of paddy and has farmers with land area and cropping index varies with certain categories. The analytical method used is Rapfish with multidimensional scaling (MDS) approach. The results showed that the sustainability index of inter-village rice farming varied between 44.13 - 71.93. Villages that are included in the quite sustainable category are Pringkasap and Kalijati with an area of more than 3 ha and an IP 200 because this village has ecological, social and technological advantages. While other villages fall into the less sustainable category. The villages with the lowest sustainability index are Kalijati villages whose land area is less than 1 Ha and has an IP of 300. The development of a sustainable rice business system in Subang and Karawang should be focused on villages with a less sustainable category. Efforts to improve the status of sustainability in the village must be directed at the attributes that are sensitive to affecting the status of sustainability, namely returning mulch and straw to the land, managing water with intermittent technology, and applying greenhouse gas mitigation technology.

Abstract
Integrated Pest Management Farmer-s Field School (IPM-FFS) is a program of human resources improvement which leads to empowering aspects of environmentally sound farming communities. To assess the effect of the implementation of the IPM-FFS, it is necessary to evaluate the changes in knowledge, attitudes and behavior of farmers in applying the four principles of IPM. One of the purposes of the implementation of the IPM-FFS is to reduce the use and application of chemical pesticides appropriately. The study was conducted from January to April 2018 in four districts of rice development centers in Siak Regency, Riau Province. The sampling technique used purposive sampling, with total sample 80 farmers consisted of 40 IPM-FFS alumni and 40 non-alumni farmers. The evaluation showed that after IPM-FFS was implemented, the percentage of farmers adopting IPM technology increases, on the application of cultivation of a healthy crop on alumni 79, 8 %, except for the use of fertilizer with a sufficient application dose of only 75 % and non-alumni an average of 65 %. IPM FFS alumni also practiced rice agro ecosystem observation regularly, and understood the existence of natural enemies and their preservation. In controlling the pests, most farmers applied preventive methods by practicing healthy crop cultivation, chemical pesticides are applied if pest attacks have reached the economic threshold, and this condition causes the use of chemical pesticides to decrease. The calendar system of using chemical pesticides regularly without regard to pests- existence, for alumni was practiced by 65 % to 0% and non-alumni from 95 % to 40 %. Rice productivity for alumni increased by 18.18% and non-alumni 12 %. Alumni revenue increased by 18, 2 % and net income increased by 29, 7 %, non-alumni of 12, 00 % and net income increased by 22.7 %. The R/C value of alumni also increased by 13, 2 % and non-alumni 11, 27 %.

Abstract
This research aimed to study the quality of tomato grew under different fertilizer applications and soil moisture levels. The green house experiment was set in a Randomized Completely Block Design. The treatments were various type of fertilizer (Liquid Organic Fertilizer/LOF, inorganic fertilizer/AB Mix, LOF+AB Mix) and different soil moisture levels (30%, 45%, 60%, 75%). Tomatoes were planted in polybags in a green house and with treatments according to the experimental design, each treatment were repeated three times. There was an interaction between type of fertilizer and soil moisture in affecting fruit diameter and fruit sugar content. The percentage of fruit infested by fruit rot was not significantly affected by type of fertilizer and soil moisture. The results showed that tomato plant treated with LOF and grew under 30% soil moisture level significantly produced smaller fruit than those treated with AB Mix only or AB Mix+LOF grew under 45%, 60% or 75% soil moisture except those treated with AB Mix+LOF grew under 45% soil moisture. Sugar content of tomato fruit harvested from plant treated with AB mix and grew under 30% soil moisture level was not significantly different from tomato grew under 45% soil moisture level and treated with AB Mix or LOF, but the sugar content was significantly higher than those grew under 60% or 75% soil moisture level treated with different type of fertilizer.

Abstract
Shallot plants are currently being cultivated in polybags and placed in residential yards. The purpose of this kind of cultivation is not to get crops to be traded, but merely as a cultivation activity for the use of limited time and space. Shallot themselves are including herbs and or medicinal plants which, although in small amounts, are needed every day. This is a study that applies a growth regulator called Fitosan which is sprayed as folliar, carried out on plants periodically and in a variety of fertilization frequencies. Fitosan levels applied are 1 ppm (K1); 2 ppm (K2) and 3 ppm (K3), while the frequency of giving Fitosan are on age of 15 dap and 45 dap (F1); on age of 15 dap, 30 dap, 45 dap (F2); on age of 15 dap, 25 dap, 35 dap, 45 dap (F3). The experiment was carried out using the Complete Randomized Design Method with an accuracy level of 95%. To determine the effect of treatments on the growth and yield of shallot bulbs, analysis of variance was performed. From observations of plant height, number of leaves and number of tillers until the age of 30 days after planting, it has not shown any significant effect from the treatment applied, but it can be expected that the F3K1 treatment will provide the most tuber yields.

Abstract
Bone is a by-product that causes bone heaps. Chicken bone contains 24-30% of Ca and 12-15% of P, so it can be used as a source of P and Ca, but not yet available. To dissolve it needs the addition of organic matter. Latosol is a soil that lacks of P and Ca. This study aims to determine the effect of application of flour from chicken bone waste and organic matters on the availability of P and Ca of Latosol and growth of corn. The study was carried out in the greenhouse of UPN “Veteran” Yogyakarta Faculty of Agriculture, on January to April 2019. The study used a completely randomized design of two factors. The first factor is the dose of chicken bone flour, are without chicken bone flour (A0), chicken bone flour 2% (A1), 4% (A2), and 6% (A3). The second factors is organic matters, are without organic matter (B0), compost 3% by weight of the soil (B1), and manure 3% by weight of the soil (B2). Each treatment was replicated 3 times. Application of chicken bone flour had a significant effect in increasing pH H2O, C-Organic, available-P, and available-Ca, plant height and plant dry weight. Application of organic matter had a significant effect in increasing pH H2O, C-Organic, available-P, available-Ca, plant height and plant dry weight. The combination of chicken bone flour and organic matters interacted each other in increasing available-Ca, while there are no interaction to affect pH H2O, C-Organic, available-P, plant height and plant dry weight.

The aim of the experiment was to examine how wheat responded to extended period of high temperatures under controlled conditions to supplement field studies with these varieties on Lombok Island. Two Indonesian wheat varieties (Nias and Dewata) and two Australian varieties (Axe and Gladius) were examined in growth room experiments at 3 different temperature regimes 32/23°C, 28/20°C and 25/15°C day/night with 12 h daylight. Temperature and photoperiod were selected to simulate conditions on Lombok Island, at lowland (32/23°C) and highland (28/20°C) sites. A third temperature (25/15°C) was selected to represent temperature in a more temperate wheat producing area. The rate of plant development increases with high temperatures up to an optimum temperatures and slower after further increases. Despite being exposed to high temperatures from establishment, the effect of high temperature was more severe during the reproductive stage as seen by the fact that yield was more affected than dry matter accumulation and yield was most strongly related to grain number. Genetic variability in response to heat stress was evident with the Indonesian varieties being more tolerant to high temperatures than Australian varieties. Nias and Dewata produced higher yield and biomass.

Abstract
Limestone post mining soil had high levels of calcium carbonate and pH, this condition causing a lack of soil P availability, so the application of mycorrhizae and organic matter is necessary. This study aims to determine the effect of mycorrhizae and organic matter, and the best combination of mycorrhizae and organic matter on soil P availability of limestone post mining and growth of maize. This study was conducted at Greenhouse in Taman Teknologi Pertanian Lebaksiu, from February to May 2019. This study used a Completely Randomized Design two factors. The first factor was the dose of mycorrhizae, namely without mycorrhizae (M0), mycorrhizae 10 g / pot (M1), and mycorrhizae 20 g pot (M2). The second factor was organic matter, namely without organic matter (B0), cow manure 20 tons / ha (B1), corn litter 20 tons / ha (B2), and legumes liter 20 tons / ha (B3). Each treatment was repeated 3 times. The result shows that the aplication of mycorrhizae had a significant effect on the increasing C-organic soil, Cation Excange Capacity (CEC), plant height and plant dry weight, but it did not significantly affect on P-available, Ca and Mg. The application of various types of organic matter had a significant effect on the increasing P-available, C-Organic soil, CEC, plant height, and plant dry weight, and decreasing soil pH (H2O) and Ca, but it did not significantly affect on Mg. There was an interaction between mycorrhizae doses and organic matters on the increasing plant dry weight of 6 WAP.

Abstract
Seeds were susceptible to drying injury in several ways i.e the delay time and the pile thickness of seed drying . The research was carried out to found the maximum delay time and the pile thickness to obtain the best seed viability and growth of rice using Innovated Drying Floor. This research was done from June to September 2019 at UPT Barongan Balai Benih Pertanian, Barongan, Sumber Agung Village, Bantul, Yogyakarta. The experiment was arranged on Split Plot design with two factors. The main plot was delay time of drying process: 2, 4 and 6 days. The subplot was the seed pile thickness: 3, 5, 7, and 9 cm. The treatments were repeated 3 times. Data were analyzed by analysis of variance 5% and test further with DMRT 5% (Duncan-s Multiple Range Test). The results showed that there was not interaction between the delay time and seed pile thickness on all parameters. The delay time of drying process: 2, 4 and 6 days and the seed pile thickness: 3, 5, 7, and 9 cm showed no significantly different on germination capacity and the growth of rice seed. The delay time of drying process until 6 days can be tolerated on the germination capacity and growth rice. The seed pile thickness until 9cm also can be tolerated on the germination capacity and growth rice.

Abstract
Garbage from dry leaves in a housing complex is often piled up and fills up green spaces. To utilize the waste of dried leaves, an organic fertilizer can be made using this dried leaves. The objection of this research is to utilize organic waste by adding bio-activator, which is called effective microorganisms (EM4). The composition for independent variables is dried leaves with EM4 20mL/5 kg dried leaves. In this research, it was used the aerobic method and stacked on a wooden box with dimension of 6 m x 6 m. Under aerobic condition, the results showed that the best content levels of C, N, P, K were C = 51.76%, N = 3.96%, P = 19.79% and K = 0.49%. For the anaerobic condition showed levels of C = 73.44%, N = 3.49%, P = 10.38% and K = 0.57%. The organic fertilizer applied to the growth of many plants in the area of Keputih Dian Regency, Surabaya.

Abstract
Herbicides was efficient but caused pollution of water sources, soil damage, and leave toxic residues in agricultural products. Environmentally friendly weed eradication can be done by using bioherbisida, such as Siam (C. odorata) leaf alelopathy. The research was conducted at Laboratory of Indonesian Legumes and Tuber Crops Research Institute (ILETRI) Malang in April 2017 using a complete randomized factorial design repeated three times. The first factors was: C. odorata extract concentration that consisted of: concentration 0% (w/v), concentration of 10% (w/v), concentration of 20% (w/v), concentration 30% (w/v). The second factor was the type of commodity that consisted of: soybeans, mungbeans and paddy. Making simplicia begins with the impregnation of fresh C. odorata leaves at 65 ˚C for 24 hours and then blended. 60, 40, 20 g of the simplicia soaked with 95% ethanol for four hours then each weight added aquades 200 ml and filtered with filter paper. Seeds was tested (arranged) on with CD paper which was wetted firstly with each extract C. odorata leaves concentrations and set aside. During the germination was doing, paper moisture was maintained by adding 10 ml of the extract C. odorata leaves of each concentration level. The observed variables were radical length (root), plumula length, and number of leaves at 4, 7 and 10 dap. The results showed that the leaves extract of C. odorata with concentration of 20% (w/v) and 30% (w/v) had potential as bioherbisida which could control weed growth.

Abstract
CVPD or greening disease is the most devastating disease on citrus production in Indonesia and in the world. It is vectored by Asian citrus psyllid (Diaphorina citri). Guava leave extract is a prospective control means for reducing psyllid population. Research was conducted to investigate the repellent effect of guava shoots to psyllids. Repellent effect of grinded dried upper shoot (leaf number 1 and 2 from the top) of 50oC and 80oC of red, white, and non-seed guava shoots to ten adult psyllids of mixed gender were determined in Y-tube olfactometer. Variation of proportion of guava leaf : citrus leaf (0:3; 1:1; 1:2; 2:1; 3:0) of guava shoots which have highest repellent effect also tested to the psyllids. The result shows that guava shoots has repellence effect to psyllids adult. The effect is reduced as the increase of drying temperature. Highest repellence effect is found from red guava shoots, followed by non-seed guava and white guava. Repellent effect of upper red guava shoots was 63.3%, 73.3%, and 76.7% on the proportion of 1:2, 1:1, and 2:1 respectively. It is suggested that the highest repellent properties is in red guava shoots and the ability will decrease in line with the increasing of drying temperature. The repellency is dose dependent. It increase with the increasing of guava leaf proportion.

Abstract
Phosphate-Solubilizing Bacteria (PSB) are microorganisms that play an important role in the biochemical cycle of the soil. This paper aims to discuss the role of these bacteria in comprehensive coverage with literature study methods. This bacterium has another role besides solubilizing phosphate in the soil such as suppressing the growth of pathogens for plants, fixing nitrogen to mobilizing heavy metals so that it is not harmful to living things. The mechanism of bacteria in carrying out this role is by secreting organic acids. The group of phosphate solubilizing bacteria varies, such as the Pseudomonas, Burkholderia to Leclercia groups

Abstract
The empowerment of Mekar farming group is conducted to establish solidarity and independence. In agribusiness, the farmers are not only solid and independent in the capital-providing but also in the cultivation techniques, post-harvest handling, distribution, institutional, and business diversity. Therefore, they need supports from the stakeholders in accordance to their necessities. The results of the research show that the stakeholders- supports come from their primary duties, so that they need an instrument to unify them. Therefore, the farmers should have the major strength which is to integrate the stakeholders dynamically. The group dynamic is seen in the reorganizing process of the organizational structure in order to adjust the form of support given by the stakeholders. It is done to develop human resources for increasing the farmers- welfare.
