Baduy people have local wisdom about the use of plants, among others, as ingredients to prevent the presence of rice pests (Oryza sativa L.). the importance of these pest-preventing plants to produce allelopathy in order to prevent rice pests (Oryza sativa L.). To find out what plants are used by Baduy people, this research is necessary. Exploration of pest control plants is carried out using the PEA (Participatory Ethnobotanical Appraisal) approach, besides that it also uses survey methods and open interview techniques. The results of the survey were 21 non-key informants and 5 key-informants from the Outer Baduy community and 12 non-key informants and 1 key informant from the Inner Baduy community, 35 species from 22 plant families were used in all rituals to prevent the presence of rice pests. . Plants that have similarities in usage by the Outer Baduy and Inner Baduy are Bamboo Wuluh leaves (Schyzostachyum iraten), Noni leaves (Morinda citrifolia), Bemban (Donax canniformis), Walang leaves (Achasma walang Val.) And Langge leaves (Homalomena cordata) . The percentages of plant organs used to prevent the presence of rice pests are leaves (77%), stems (17%) and fruit (6%). The method of processing plants as raw material for rice pest prevention ingredients is to cut them in small volumes / chop (39.74%), pound (52.56%), ferment (3.85%) and burn (3.85%). Baduy rituals in preventing the presence of rice pests include 5 types namely Ngubaran Samara Pungpuhunan ("Treatment" of Main Plants), Ngubaran Cangkudu ("Treatment" of Noni), Ngubaran Bangban ("Treatment" of Bemban / Donax canniformis), Fumigation, and Leuit Susumpingan (Lumbung offerings)

Eradicating rice pests in South Kualuh is difficult to do optimally, because most farmers do not understand the types of pests that attack their rice plants. The objective of this study was to obtain information about the type of pest insects in rice plants and to find out the diversity index of insect pests in rice plants. This research was conducted using trap method and collection of insects was done using a insect net. Observation data was analised using Shanon Wiener (H) diversity / diversity index. The result showed 13 types of pest insects which belongs to 10 families. That is Tettigonia sp.(Linnaeus, 1758), Sogatella furcifera (Horváth, 1899), Nephotettix virescens (Distant, 1908), Cofana spectra (Distant, 1908), Atractomorpha crenulata (Fabricius, 1793), Erotides sp.(Laporte, 1836), Leptocorisa acuta (Thunberg, 1783), Aulacophora indica (Gmelin, 1790), Chrysochus cobaltinus (LeConte, 1857), Silba capsicarum (McAlpine, 1956), Hercostomus germanus (Wiedemann, 1817), Cnaphalocrosis medinalis (Guenée, 1854), Scirpophaga incertulas (Walker, 1863). The diversity index of rice pest insects was categorized as moderate with a value of 2,35 and a dominance index of 0,108. This value indicates that the distribution of species is evenly distributed so that no insect species dominates in the area.

Rice straw is a waste from rice plants that contains 37.71% cellulose, 21.99% hemicellulose, and 16.62% lignin. High cellulose content in rice straw can be used as raw material for the manufacture of Carboxymethyl Cellulose (CMC). CMC is a cellulose derivative widely used in food, pharmaceutical, detergent, textile and cosmetic products industries as a thickener, stabilizer of emulsions, or suspensions and bonding. This study aims to process rice straw waste into CMC with variations in sodium monochloroacetate of 5,6,7,8 and 9 grams. The method used in this research is by synthesis using 15% NaOH solvent, with a reaction time of 3.5 hours and 5 grams of rice straw. The results showed that the best CMC was obtained at a concentration of 9 grams of sodium monochloroacete with a yield characterization of 94%, pH 6, water content of 13.39%, degree of substitution (Ds) of 0.80, and viscosity of 1.265 cP.

Experiments were carried out to assess some insecticide modules against major insect pests of rice. Each module consists of a basal application of carbofuran 3G @ 1 kg a.i ha-1 at 20 DAT and Rynaxypyr 20 SC @ 30 g a.i ha-1 at 45 DAT except untreated control. All modules differ with each other only in third treatment which was applied in 65 DAT. The third treatment includes: Imidacloprid 17.8 SL @ 27 g a.i ha-1, Pymetrozine 50 WG @ 150 g a.i ha-1, Triflumezopyrim 106 SC @ 27 g a.i ha-1, Buprofezin 25 SC @ 250 g a.i ha-1; Glamore (Imidacloprid 40+Ethiprole 40% w/w) 80 WG @ 100 g a.i. ha-1, Thiacloprid 24 SC @ 60 g a.i ha-1, Azadirachtin 0.03 EC @ 8 g a.i ha-1, Dinotefuran 20 SG@ 40 g a.i ha-1 and untreated control. All the treated plots recorded significantly lower percent of dead heart, white ear- head caused by stem borer and silver shoot caused by gall midge. Module with Pymetrozine 50 WG @ 150 g a.i ha-1 treated plot recorded significantly higher per cent reduction of plant hoppers (>80% over untreated control) and produced higher grain yield (50.75 qha-1) than the other modules. Among the different treated modules the maximum number of spiders was found in Azadirachtin 0.03 EC @ 8 g a.i ha-1 treated module plot followed by other treatments.

Salah satu upaya untuk meningkatkan produksi dan mutu benih di lahan salin yaitu melalui penggunaan metode ratun dengan penambahan bakteri sintetik Synechoccocus sp. Penelitian ini bertujuan untuk mengetahui produksi dan mutu benih padi ratun yang tercekam salinitas dengan penambahan bakteri sintetik Synechoccocus sp. Penelitian dilaksanakan pada bulan Juli - Desember 2015 di Desa Suco, Kecamatan Mumbul Sari Jember dan Laboratorium Teknologi Benih Politeknik Negeri Jember. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok Faktorial (RAK) dengan 2 faktor dan 3 ulangan. Faktor pertama adalah cekaman Salinitas (S) yang terdiri dari 5 taraf, S1 = tanpa cekaman (kontrol), S2 = cekaman salinitas 1000 ppm, S3 = cekaman salinitas 2000 ppm, S4 = cekaman salinitas 3000 ppm, S5 = cekaman salinitas 4000 ppm. Faktor kedua inokulasi bakteri sintetik Synechoccocus sp. (B), yang terdiri dari 2 taraf, B1 = tanpa inokulasi bakteri (kontrol), B2 = Inokulasi sintetik Synechoccocus sp. Data dianalisis menggunakan uji F (ANOVA) dan dilanjutkan dengan perhitungan Duncan’s Multiple Range Test (DMRT). Hasil penelitian menunjukan perlakuan salinitas 1000 ppm (S2) menghasilkan jumlah anakan ratun produktif tertinggi yaitu 19,33 anakan. Cl- mempunyai fungsi utama dalam reaksi fotosintesis sehingga cekaman salintas pada perlakuan 1000 ppm (S2) dapat ditoleran oleh tanaman padi varietas Ciherang pada fase vegetatif. Pemberian Bakteri (B) Synechococcus sp. mampu menghasilkan tunas ratun tertinggi pada fase vegetatif yaitu 40,10 cm. Interaksi dari dua perlakuan menunjukan hasil yang nyata pada parameter jumlah gabah bernas yaitu cekaman salinitas 4000 ppm dengan inokulasi bakteri (B2S5) menghasilkan gabah bernas yang paling tinggi sebesar 99,06 butir. Inokulasi tanaman dengan Synechococcus sp. mampu meningkatkan kandungan nitrogen dan kandungan klorofil dalam jaringan tanaman. Interaksi antara cekaman salinitas 1000 ppm dengan inokulasi bakteri (B2S2) menghasilkan produksi per Ha yang paling tinggi yaitu 1,389 ton dan potensi produksi per Ha tertinggi yaitu 1.66 ton/ha.
