The study was conducted in Ciptamarga Village, JayakertaSubdistrict, Karawang District, West Java - Indonesia within one cropping season in 2018. The study was started in September 2018 and terminated in December in the same year. The study site was a large irrigated rice farm belong to farmers with size around 40 hectares. The farmers plantedInpari 32 and Inpari 42 rice varieties twice a year. Rodent has been recognized as the most destructive pest in this area which accompanied by brown plant hopper, stem borer and virus as the minor pests and disease of the rice crop. The objective of this study was to control the rice field rats as the main pest contributing some losses to the local farmers. The second purpose was to determine the effectiveness of our ecologically based rat control technology which implemented by integrating several components. At the beginning of cropping season we performed sanitation, mass hunting and fumigation on the main habitats which continued by setting a TBS (Trap Barrier System) and LTBS (Linear Trap Barrier System) in different habitats. The TBS functions as a lure crop by planting those rice crop three weeks earlier than surrounding areas, as the rice field rats prefer to the generative stage. The LTBS was assembled to protect the next staggering crop by trapping rats regularly on their main habitats within a whole season. LTBS was also effective to catch the rats which move back and forthto the rice field and village after harvesting. We have set four units of TBS and four units of LTBS during the cropping season which incorporated with 48 bubu traps. We also protected seed nurseries by erected plastic fence combined with 16 bubu traps along the fence. We recorded the number of rat captured from those activities along the cropping season. These components of rat control technology were effectively catch lots of them within a cropping season accounted for 2,306 individuals. These actions provided positive impacts to the local farmers by decreasing rat population and increasing the yield. The average of yield increased from 1.9 ton/ha to 6.4 ton/ha after we performed rat control intensively. The yield data before and after implementation of rat control technology was compared and analyzed. The results indicated that there was a significant difference between those values. From this point it seems that farmer eager to adopt the technology for the next planting season.The study was conducted in Ciptamarga Village, JayakertaSubdistrict, Karawang District, West Java - Indonesia within one cropping season in 2018.

Rice production and the empowerment of farmers in the subdistrict of Pallangga, Gowa Regency, South Sulawesi Province 南苏拉威西省果瓦县帕朗加街道的水稻生产和农民赋权
Farra Safira, M. Dimyati, A. Damayanti
Rice production is vital because of its impact on the national economy. An important factor in achieving the production target is the capability of farmers to manage their agricultural land. This study aims to determine whether there is a correlation between rice production and the empowerment program of farmers in Tetebatu Village, Toddotoa Village, and Julubori Village using a descriptive approach. The assessment parameters are rice production, government programs, and farmers’ knowledge in managing land. This approach was carried out by field observations and interviews with informants such as the Head of the Division of Food Crops in Gowa Regency, extension agents, farmer group leaders, and farmers. Primary and secondary data are comparatively analyzed. This aims to be able to see and describe the phenomena regarding the empowerment of farmers in the three villages. The results showed that the empowerment of farmers usually done by doing field school, socialization, technology demonstration, and making demonstration plots. The highest rice production in 2018 is in Julubori Village which is 15 tons/ha, the intermediate rice production is in Tetebatu Village which is 6.9 tons/ha, and the lowest production is in Toddotoa Village which is 6.8 tons/ha. The main contributing factor for the success of rice production is the implementation of government-supported programs. The inhibiting factors are the low quality of human resources, the distribution of seeds and the planting season that is not a series of time, the limitation of agricultural equipment, and the inadequate availability of irrigation networks.Rice production is vital because of its impact on the national economy.

Evaluation of nutritional value of linseed protein quality in lactating Ettawa crossbreed dairy goats 泌乳期Ettawa杂交奶山羊亚麻籽蛋白品质的营养价值评价
S. D. Widyawati, A. Hanifa, R. F. Hadi, W. Suprayogi
The study aimed to determine the effect of linseed use on lactating Ettawa crossbreed dairy goat rations in terms of protein quality had been carried out both in vitro and in vivo. In vitro experiments were carried out using rumen fluid as a source of inoculum from 5 Simmental cows. While in vivo experiments were carried out using 16 heads of lactating dairy crossbreed goat. Sixteen heads of goats were allotted according to completely randomized design. The goats were distributed into 4 treatments. The treatments consisted of basal ration consisted of 11.8% forage and 88.2% concentrate (T1), and ration consisted of 11.8% forage and 78.9% concentrate supplemented with 9.3% linseed (T2), 9.3% linseed protected with 10 g/kg formaldehyde (T3), or 9.3% linseed protected with 34 g/kg cinnamaldehyde (T4). All goats received Odot Grass and concentrate at the level of 5% of body weight. The results showed that the protection using both formaldehyde and cinemaldehyde had no significant differences (P <0.05). Ammonia concentration is not affected by the treatment of protected linseed use. Microbial proteins analyzed by the Lowry method gave different results not significantly. This shows that the four treatments were able to provide nutrients for rumen microbial. Protein digestibility of rations and protein contained in milk from the four treatments showed that it did not differ between treatments. It is concluded that rations containing protected or unprotected linseed have no effect on ammonia concentration, protein micobial in rumen fluid, protein digestibility and milk protein.The study aimed to determine the effect of linseed use on lactating Ettawa crossbreed dairy goat rations in terms of protein quality had been carried out both in vitro and in vivo.

Every plants need an environment which is in accordance with its adaptability. However, the environment always changes so that it requires regular analysis to maintain plant fertility. Environmental data such as temperature, humidity from soil and air, rainfall, light intensity can be processed using computer algorithms in the form of a sequential (time series) matrix. The paper proposed a sequential Fuzzy Association Rule Mining (FARM) for plants environment classification using Internet of Things (IoT). FARM is used to extract association rule in form of fuzzy memberships from plant environment data that collected from sensors of IoT. Fuzzy is used to facilitate grouping of sensor data and detect changes in the environment when the degree of membership becomes irrelevant. Fuzzy membership degrees are also mapped based on time series to interpret routine environmental changes. The paper showed results of a FARM algorithm for plant environments and prototypes from IoT circuits.

Rice-husk biochar for better yield of lowland rainfed rice in Lombok, Indonesia 在印度尼西亚龙目岛,稻壳生物炭提高了低地雨养水稻的产量
L. Hadiawati, T. Sugianti, Y. Triguna
Biochar is one of soil amendment that less popular to apply on rice cultivation when compared to other horticulture commodieties in West Nusa Tenggara (WNT) Province. This study aimed to evalute the effect of rice husk biochar application on growth and yield of rice grown on lowland rainfed of WNT Province. Experiment was carried out from January to April 2017 at Narmada Research Station of AIAT (Assessment Institute for Agricultural Technology) of WNT Province, Indonesia. Experimental design used was factorial complete randomized block design for two factors with three replications. The first factor was the application of organic fertilizer; (T1) control at 0 t/ha, (T2) cattle manure at 5 t/ha, (T3) cattle manure and biochar (50:50) at 5 t/ha. The second factor was rice varieties; (V1) Inpari 41 Tadah Hujan Agritan, (V2) Inpari 42 Agritan GSR, and (V3) Inpari 43 Agritan GSR. The results showed a significant interaction effect on above-ground (AGB) biomass where the highest AGB obtained in T3V3. Higher AGB was indicating better growth and it was likely contribute to higher grain yield that was found also at T3V3. Significant main effect of organic fertilizer were found on plant height, percentage of filled spikelet, and 1000 grain weight. Although there was no significance difference, in average, additional biochar in T3 improved grain yield to 6.47 t/ha, followed by T2 at 6.11 t/ha, and the lowest was T1 at 5.80 t/ha.Biochar is one of soil amendment that less popular to apply on rice cultivation when compared to other horticulture commodieties in West Nusa Tenggara (WNT) Province.

S. Y. Lumbessy
Semi-sterile culture is an initial maintenance stage that is essential to be optimized to get sterile seaweed explants (axenic explants). The purpose of this study is to determine the effect of using culture media on the weight gainand survival rate of the Gracilaria salicornia seaweed (parental) in semi-sterile culture. This research was conducted at Tissue Culture Laboratory of Lombok Marine Aquaculture Center, Sekotong, West Nusa Tenggara. The study was carried out using three different media treatments such as Provasoli Enriched Seawater (PES), hydroponic, and Steril Sea Water (SSW) as controls. The results showed that hydroponic media have the highest average weight and survival rate of G. salicornia (48.76 g and 99.75%). The results were not significantly different from SSW media but were significantly different from PES media.Semi-sterile culture is an initial maintenance stage that is essential to be optimized to get sterile seaweed explants (axenic explants).

Many reserches reported that brown algae is main source of by fertilizer and biostimulant for supporting growth and development of agriculturaland horticultural plants. This article reports growth and yield of rice plant sprayed with different concentration of Sargassumpolysistum, one of brown algae species. Since the age of rice plant was 21 days after planting. The plants were sprayed with 0, 5, 10,15, 20% of Sargassumpolysistum extract. The plants were sprayed one a week during vegetative growth. The results show that concentration of Sargassumpolysistumincreased the growth of rice plants until maximum concentration 10%. However, when this extract applied in more than 10%, the growth was decreased similar phenomena was also demostrated in yield parameters, such as penicle number and seed weights.
许多研究报道,褐藻是支持农田和园艺植物生长发育的肥料和生物刺激素的主要来源。本文报道了施用不同浓度的褐藻(sargasumpolysistum)对水稻生长和产量的影响。自水稻种植后21天起。分别用0、5、10、15、20%的皂荚提取物对植株进行喷施。这些植物在营养生长期间每周喷洒一次。结果表明,在最大浓度为10%之前,聚马尾草对水稻植株的生长有促进作用。然而,当添加量超过10%时,生长下降,在产量参数(如青霉数和种子重)中也表现出类似的现象。

The test stand for proper operation shall have a equipped of auxiliary systems. One of them is the track gauge adjustment system. The original gauge adjustment mechanism revealed shortcomings caused by the wear in operation. The new solution of track gauge setup on the test stand consists of hydraulic circuit design, construction, control and subsequent verification of reliability and proper operation. For proper operation and accurate results, the test bench was fitted with an apparatus for centering the rotating rail. The measuring apparatus shows what gauge is set on the rotating rails and in which position the individual rail are located. Measurements have been made to verify the functionality of the system and to help set the correct function of the hydraulic cylinders. By examining the transverse forces at unloaded rotating rails, the proper function of the hydraulic system has been verified. After load of the rotating rails with wheelset was monitored by the process of the guiding (transverse), longitudinal and wheeled (vertical) forces.The test stand for proper operation shall have a equipped of auxiliary systems.
