Conserving Environment Through Local Wisdom of Organic Vegetable Crops in West Java Indonesia

Farmers in the paddy field farming faces some fundamental problems caused by the narrower tenure due to increased population and land inheritance, creation of breakthrough technologies to increase the productivity of rice farming and farmers' income increasingly difficult for farmers to diversify motives are often more oriented to the income stabilization. West Java is better known as the rice granary, is also a center of vegetables in Indonesia. Vegetable farming has been fused with the local community, especially for upland farmers. The last few years this development not only in vegetable crops in the highlands but try also try in the lowlands in the paddy field. Along with the above conditions, the policy support necessary to achieve the expected results. One obstacle in the application of vegetable farming is the lack of use of the means of production as a result of lack of financial ownership of farm households. The purpose of research is (a) reveals variability of farm crops especially vegetables Onion, Long Beans, cauliflower and cucumbers. (b). And to evaluate the extent to which government policy support for horticultural commodities especially vegetables in West Java. The research was conducted in two districts of Indramayu (Chilli Red, Red Onion and Cauliflower), Falkirk (cucumber and bean length) of West Java Province. , Amounted to a total of 50 respondents drawn farmers. The results showed that farm incomes various vegetables (horticulture) is higher than the income of rice farming, especially in the red pepper (673%), onions (415%), while the rate of return based on a variety of vegetable farming is higher than the benefits of rice farming, especially red pepper (776%), onions (279%) cauliflower (200%) and beans (144%).

Iskandar BS, Iskandar J, Partasasmita R, Alfian RL. 2018. Planting coffee and take care of forest: A case study on coffee cultivation in the forest carried out among people of Palintang, Highland of Bandung, West Java, Indonesia. Biodiversitas 19: 2183-2195. People of Palintang hamlet of highland of Bandung, West Java have interacted with the forest ecosystem for a long time. In the past, initially, they cultivated forest by practicing swidden farming system (ngahuma) based on the traditional ecological knowledge which strongly embedded with local culture. During the Dutch colonial, some people of Palintang involved as the laborer of various activities of the culture system in the forest. After Indonesian independence, Palintang people have participated as laborers in various activities in the mixed-cropping (tumpangsari) program of the Forestry Service (Dinas Kehutan) and later on the State Forestry Corporation (Perhutani). In 1983, the tumpangsari program was formally prohibited because of its potency to cause environmental destructions, but some people of Palintang have continuously planted vegetables in the forest to get household income. Although the cultivation of vegetables in the forest provided some economic benefits, however, some forest destruction and environmental destructions, including soil erosion, landslide, pesticide pollution have not been inevitable. In 2005 Perhutani launched the management of forest resources together with the community (PHBM=Pengelolaan Sumber Daya Hutan Bersama Masyarakat), mainly by introducing Arabica coffee (Coffea arabica L) to be planted in the pine (Pinus merkusii Jungh) forest to replace the farming of vegetables in the forest. This paper elucidates the historical process of introduction of Arabica coffee in the pine forest of Palintang through the PHBM program of Perhutani. The method used in this study was qualitative with descriptive analysis. Some techniques, namely observation, semi-structured interview, and participant observation were applied in this study. The result of the study showed that the introduction of coffee had been adopted by rural people of Palintang through a long time process with learning by doing. It was revealed that several factors caused the residents accepting coffee plants to be cultivated on forest land, i.e., coffee plants were only once planted in the past in their area, and the area is suitable for coffee cultivation. Besides, coffee has been considered to be planted and give economic benefits; and was initially planted in combination with annual crops, including vegetables, so that before the coffee is produced, the rural people can still produce annual agricultural products such as vegetable crops. However, when the coffee started to produce, time allocation, labor, and capital were more emphasized on the cultivation of coffee instead of vegetable crops; thus, cultivation of vegetables is gradually reduced and even stopped. The forest ecosystem of Palintang can be utilized and maintained by the rural community as indicated by their perception of the forest ecosystem. Thus, people of Palintang have increased awareness that they want to protect forest areas after their coffee cultivation in the forest area provides economic benefits to them.

Gemini Virus

Kutukebul Bemisia tabaci (Hemiptera: Aleyrodidae) merupakan hama penting pada pertanaman cabai merah dansatu-satunya penular virus Gemini (virus kuning). Virus kuning keriting yang disebabkan oleh virus Gemini sekarang menjadiepidemik di berbagai daerah seperti Jawa Barat, Jawa Tengah, DI Yogyakarta, Sumatera Utara, dan Lampung, dengan intensitasserangan antara 20 sampai 100%. Tujuan penelitian untuk mendapatkan predator dari jenis Coccinellidae yang benar-benar efektifuntuk mengendalikan B. tabaci pada pertanaman sayuran khususnya cabai merah. Kajian potensi Coccinellidae sebagai predatorB. tabaci dilaksanakan pada tiga tahap percobaan, yaitu eksplorasi predator, uji daya pemangsaan, dan uji preferensi. Eksplorasipredator dilaksanakan dengan metode survei di tiga provinsi sentra produksi cabai merah dan daerah endemi penyakit virus kuningyaitu Jawa Barat (Kabupaten Cirebon dan Garut), Jawa Tengah (Kabupaten Brebes dan Magelang), dan DI Yogyakarta (KabupatenBantul dan Sleman). Eksplorasi predator dilakukan dengan mengumpulkan secara langsung serangga yang diduga sebagai predator(pendugaan predator berdasarkan pengamatan dan studi literatur), kemudian di inventarisasi dan diuji keefektifannya sebagai musuhalami melalui uji daya pemangsaan dan preferensi terhadap B. tabaci dan hama kutu daun cabai lainnya. Penelitian dilaksanakan ditiga provinsi, yaitu Jawa Barat (Kabupaten Cirebon dan Garut), Jawa Tengah (Kabupaten Brebes dan Magelang), dan DI Yogyakarta(Kabupaten Bantul dan Sleman) dari bulan Mei sampai dengan September 2010. Hasil eksplorasi dan identifikasi ditemukan 11 jenispredator yang berpotensi sebagai musuh alami B. tabaci, yang terdiri atas delapan jenis dari ordo Coleoptera famili Coccinellidae yaituMenochilus sexmaculatus, Coccinella transversalis, Verania lineata, Illeis sp., Curinus coeruleus, Delphastus sp., Harmonia sp., danMenochilus sp., satu jenis dari famili Stapilinidae yaitu Paederus fuscipes, satu jenis dari ordo Hemiptera: famili Miridae (Compylommasp.), satu jenis dari ordo Neuroptera famili Hemerobiidae, dan satu jenis ordo Diptera (Condylostylus sp). Berdasarkan distribusi,kelimpahan, uji daya pemangsaan dan uji preferensi terhadap B. tabaci, maka spesies predator yang berpotensi tertinggi sebagaiagens hayati B. tabaci ialah V. lineata, kemudian diikuti oleh M. sexmaculatus dan C. transversalis (Coleoptera : Coccinellidae).Pemanfaatan predator B. tabaci potensial dapat diuji dan diaplikasikan pada skala yang lebih besar.ABSTRACTWhitefly Bemisia tabaci (Homoptera:Aleyrodidae) is one of important pest on vegetable crops, especially on family of Solanaceae, particularly on chili peppers.Whiteflybecomes very critical pest because it become an important vector for Gemini virus. Many regions in West Java, Central Java,Yogyakarta, South Sumatera, and Lampung became endemic of leafroll yellow virus caused by Gemini virus in the recent year withdisease intensity from 20 till 100%. Objective of this research was to obtain potential and effective predators to control B. tabacifrom West Java, Central Java, and Yogyakarta. Study of Coccinellidae potency as natural enemy to control B. tabaci have beendone through three stages started from predator exploration, predation, and preference test. Predators exploration was done in chilipepper production centre area in three province, namely West Java (Cirebon and Garut Districts), Central Java (Brebes and MagelangDistrict), and Yogyakarta (Bantul and Sleman District). Those areas were choosen as exploration area because beside as chili peppersproduction centre areas, they were also indicated as Gemini virus endemic area. Predator exploration was done by collecting insectsthat were indicated as predator (based on literature study). Predators that found in this exploration then be identified and tested fortheir effectiveness as natural enemies (predation and preference test). From the exploration and identification, there were found11 species of predator, nine of eleven predator were member of Coleoptera (eight of them were member of family Coccinellidae,namely Menochilus sexmaculatus, Coccinella transversalis, Verania lineata, Illeis sp., Curinus coeruleus, Delphastus sp., Harmoniasp., Menochilus sp., and one of them was include in family of Staphylinidae Paederus fuscipes. We also find one species fromordo Hemiptera, i.e. member of Miridae family: Compylomma sp., one species from ordo Neuroptera, family Hemerobiidae, andone species from ordo Diptera (Condylostylus sp). Based on distribution, severity and effectiveness test, it could be concluded thatpredator species which have the highest potency as natural agent for controlling B. tabaci were V. lineata, M. sexmaculatus, and C.transversalis (Coleoptera : Coccinellidae). The use of B. tabaci high potential predators can be tested and applied in higher scale.The use of B. tabaci high potential predators can be tested and applied in higher scale.
