Abstract

Nematoda daun Aphelenchoides merupakan salah satu patogen tanaman yang memiliki kisaran inang yang luas dan menyebabkan kehilangan hasil panen. Metode konvensional telah sering digunakan dalam pengendalian nematoda termasuk nematisida kimia, perawatan air panas, dan nematisida hayati tetapi memiliki keterbatasan. Hal ini memerlukan eksplorasi metode alternatif yang ramah lingkungan dan efektif, seperti teknologi gelombang ultrasonik. Penelitian bertujuan mengetahui efektivitas gelombang ultrasonik dalam eliminasi nematoda daun Aphelenchoides pada umbi bawang serta pengaruh pada pertumbuhan umbi bawang. Ekstraksi nematoda menggunakan metode pengabutan (mist chamber) dan perendaman air dingin. Nematoda diidentifikasi berdasarkan karakter morfologi. Umbi bawang merah yang telah diinfestasikan Aphelenchoides diberi perlakuan ultrasonik dengan lama perlakuan selama 26, 30, 37, 44, 60 menit dan kontrol. Umbi bawang yang telah diberi perlakuan ultrasonik ditanam di pot dan diamati parameter pertumbuhannya sampai panen. Data ditabulasikan di Microsoft Excel dan diolah menggunakan SAS JMP. Perlakuan ultrasonik dengan durasi yang lebih dari 37 menit menghasilkan tingkat mortalitas yang tinggi (≥84,00%).  Waktu papar yang berbeda menunjukkan pengaruh yang tidak berbeda nyata dengan kontrol pada tinggi tanaman dan panjang akar. Lebih lanjut, perlakuan ultrasonik dengan durasi yang lebih lama (≥ 37 menit) sangat efektif dalam menekan populasi nematoda Aphelenchoides tanpa memengaruhi pertumbuhan tanaman bawang merah.

Abstract

Sukoharjo Regency, Central Java, is an example of successfully implementing rice planting using the Planting Index 400 (IP-400). This study aimed to analyze the difference in total farming costs between IP-400 and non-IP-400 rice varieties and their sustainability. Farmers in Sukoharjo have succeeded in planting rice three to four times a year in rice fields with technical irrigation. This activity was carried out in five stages, i.e. 1) a Discussion with the Head of the Sukoharjo Regency Agriculture and Fisheries Service, Central Java and his staf; 2) Focus Group Discussion (FGD) with the Head of the Sukoharjo Regency Agriculture and Fisheries Service, Heads of Farmer Groups and their members, Delegates from the Directorate General of Food Crops, Ministry of Agriculture, as well as related parties; 3) Field visits to rice seed entrepreneurs; 4) Field visits to "integrated farming" entrepreneurs who implement IP-400 rice cultivation; and 5) Field visits and interviews with farmers accompanied by extension workers and the Department of Agriculture as farmer advisors. Socialization and discussions have effectively increased stakeholders’ understanding of the implementation of IP-400 rice planting. This success is due to adequate technical support and infrastructure and close cooperation between farmers, local governments, and other related parties. By continuing these efforts and adapting to local conditions, the IP-400 program can become a model for other regions to sustainably increase rice production

Abstract

The IPB rice technology dissemination program implemented in Pangumbahan Village, Ciracap District, Sukabumi Regency, aimed to improve the knowledge and skills of fostered partner farmers through technology transfer and innovation to increase land utilization and support the intensification of rice production. This service activity involved four active IPB students, four IPB lecturers, and the Sabilulungan Farmer Group Union (Gapoktan) as fostered partners. The method of activity implementation consisted of observation, mapping of potential and problems, program implementation, and monitoring and evaluation of the program. The implementation of the IPB rice technology dissemination program began with field observations, including a survey of field conditions. Focus group discussion (FGD) activities were conducted to map the potential and problems in the community. Program implementation consisted of training and assistance in transferring technology and innovation in rice cultivation. Monitoring and evaluation were conducted through in-depth interviews and discussions with the assisted farmers. Through the establishment of demonstration plots of IPB 3S and IPB 9G rice varieties, the community can increase its knowledge and skills regarding the development of their commodities. The implementation of technology transfer through training and practice of the IPB Prima rice cultivation technique can encourage more efficient and productive rice cultivation.
