Abstract

Corn is one of the food crops in Indonesia that has great potential to be developed, one of which is Waxy Corn. This type of corn has a high amylopectin content, but its productivity is still relatively low. One effort to increase the productivity of Waxy Corn is through the use of liquid organic fertilizer from tofu waste. This research was conducted on the land of the Jember State Polytechnic in July-October 2024 using a randomized block design with a single treatment, namely the comparison of the concentration of liquid organic fertilizer tofu waste. There are six treatment levels, namely control (0 ml/l), 26 ml/l, 28 ml/l, 30 ml/l, 32 ml/l, and 34 ml/l. The data were analyzed using analysis of variance, and if there was a significant difference, a further test of the smallest significant difference was carried out. The results showed that the treatment of liquid organic fertilizer with a concentration of 34 ml/l had a significant effect on the stem diameter at the age of 21 days after planting and the weight of the cob per sample. The concentration of 30 ml/l affected the cob diameter, while the concentration of 32 ml/l affected the cob weight per plot. The parameters of plant height and biomass weight did not show significant differences.

Abstract

Kelompok Tani Ngudi Kaweruh merupakan salah satu kelompok tani aktif di Dusun Tegal Rejo terletak di Desa Sabrang, Kecamatan Ambulu, Kabupaten Jember. Salah satu kendala yang banyak dikeluhkan petani adalah pupuk subsidi yang terbatas dan sulit didapat. Selain itu, untuk memperoleh pupuk subsidi harus melalui prosedur yang tidak mudah. Petani akhirnya beralih menggunakan pupuk anorganik non subsidi yang dijual dengan harga tinggi. Selain itu, penggunaan pupuk dan pestisida kimia yang berlebihan akan meningkatkan biaya produksi sehingga akan menurunkan keuntungan. Oleh karena itu, diperlukan solusi alternatif pemupukan yang aman dan bekelanjutan. Berdasarkan permasalahan Mitra, alternatif solusi yaitu program penerapan kompos blotong sebagai substitusi pupuk anorganik di kelompok tani tersebut. Program dilaksanakan sejak bulan Juli – September 2024. Tahapan kegiatan meliputi survey dan sarasehan, sosialisasi kompos blotong, diskusi, dan pendampingan. Hasil kegiatan menjelaskan bahwa kelompok tani memiliki cara pandang lain terhadap pupuk anorganik, keberlanjutan agroekosistem, dan ekonomi sosial

Abstract

ABSTRAKBemisia tabaci adalah salah satu hama pada kedelai yang dapat menyebabkan penurunan produksi hingga 80%. Umumnya petani masih menggunakan insektisida sintetis yang menyebabkan hama resisten dan membunuh arthropoda menguntungkan. Perlu adanya alternatif insektisida yang aman bagi lingkungan maupun manusia. Penelitian ini bertujuan mengkaji pengaruh aplikasi asap cair arang sekam (ACAS) padi pada populasi kutu kebul (Bemisia tabaci). Tiga jenis perlakuan yang digunakan adalah: G3: ACAS grade 3 konsentrasi 3%; G2: ACAS grade 2 konsentrasi 4%; dan IMI: insektisida sintetis berbahan aktif imidakloprid. Penelitian ini menggunakan metode perbandingan perlakuan. Setiap perlakuan diaplikasikan pada plot berukuran 20 m2. Data hasil pengamatan dianalisa menggunakan uji non parametrik Kruskal Wallis. Hasil pengamatan populasi B. tabaci pada semua jenis perlakuan mengalami peningkatan seiring bertambahnya umur tanaman dan mengalami penurunan mulai 52 HST selanjutnya semakin menurun hingga 59 HST. Populasi B. tabaci secara keseluruhan akibat aplikasi imidakloprid sebanyak 15.70 individu berbeda nyata jika dibanding dengan aplikasi ACAS grade 3 maupun grade 2. Asap cair arang sekam grade 3 konsentrasi 3% mengakibatkan populasi B. tabaci 28.94. Perlakuan ini lebih berpotensi menekan populasi B. tabaci dibanding ACAS grade 2 konsentrasi 4% yang menekan populasi B. tabaci menjadi 29.13. Kedua perlakuan ACAS tersebut masih kurang optimal jika dibandingkan insektisida sintetis berbahan aktif imidakloprid dalam menekan populasi B. tabaci pada tanaman kedelai edamame.ABSTRACTBemisia tabaci is a pest in soybeans that can cause a reduction in production of up to 80%. Generally, farmers still use synthetic insecticides which cause pest resistance and kill beneficial arthropods. There is a need for alternative insecticides that are safe for the environment and humans. This research aims to examine the effect of application of rice husk charcoal liquid smoke (ACAS) on whitefly (Bemisia tabaci) populations. The three types of treatment used are: G3: ACAS grade 3 concentration 3%; G2: ACAS grade 2 concentration 4%; and IMI: synthetic insecticide containing the active ingredient imidacloprid. This research uses a treatment comparison method. Each treatment was applied to a plot measuring 20 m2. Observation data were analyzed using the Kruskal Wallis non-parametric test. The results of observations of the B. tabaci population in all types of treatment increased as the age of the plant increased, and decreased starting at 52 HST and decreasing further until 59 HST. The overall population of B. tabaci due to imidacloprid application was 15.70 individuals, which was significantly different when compared to the application of ACAS grade 3 or grade 2. Liquid smoke from grade 3 husk charcoal with a concentration of 3% resulted in a B. tabaci population of 28.94. This treatment has more potential to suppress the B. tabaci population compared to ACAS grade 2 concentration 4% which suppresses the B. tabaci population to 29.13. These two ACAS treatments are still less than optimal compared to the synthetic insecticide containing the active ingredient imidacloprid in suppressing the B. tabaci population in edamame soybean plants. Keywords: bioinsecticide, GCMS, whitefly, liquid smoke, bemisia tabaci

Abstract

The Ngudi Kaweruh Farmer Group is one of the farmer groups in Tegal Rejo Hamlet, Sabrang Village, Ambulu Subdistrict, Jember Regency, which cultivates shallots. The obstacle complained about by this farmer group is the high price of inorganic pesticides in the field. Pesticides do not receive subsidies from the government, while in shallot farming, farmers cannot avoid the use of inorganic pesticides. Based on the problems faced by our partners, we provided an alternative solution, namely the use of Metarhizium as a biological agent to control red onion pests. The program was implemented from February to May 2025. The stages of implementation included surveys and discussions, socialization of the use of Metarhizium, and discussions and assistance. The results of the activity showed that the use of Metarhizium can save farmers' expenses for purchasing inorganic pesticides, control pests, and is environmentally friendly. Farmers can see the real impact of using Metarhizium in shallot cultivation. Therefore, farmers do not hesitate to use Metarhizium to control pests that attack shallots.
