Abstract

Aquaponics is an integration between fish and plant cultivation that benefits these two sectors. The development of aquaponics at the farm level can be an effort to increase food security. This community service activity aims to apply aquaponic leaf vegetable cultivation techniques, to optimize the facilities available at Gapoktan Bina Sejahtera (fish ponds). Activities carried out by counseling methods, training and demolots to farmers regarding the cultivation techniques of leaf vegetables and red tilapia with an aquaponic system. During the activity, monitoring was also carried out by a team of service lecturers, assistance by student teams and evaluation through pretest and posttest. This community service activity is able to provide new experiences, and increase farmers' knowledge and skills in cultivating red tilapia and leaf vegetables with an aquaponic system.
SERANGAN Spodoptera frugiperda J.E SMITH (LEPIDOPTERA: NOCTUIDAE) DAN PARASITOIDNYA DI KABUPATEN/KOTA BOGOR, INDONESIA: Attack of Spodoptera frugiperda J.E Smith (Lepidoptera: Noctuidae) and Its Parasitoid in Parts of Bogor, Indonesia Muhammad Waliyudin; Nur Rochman; Muhammad Zainal Fanani

Abstract

Spodoptera frugiperda J.E Smith (Lepidoptera: Noctuidae) merupakan hama asing invasif yang menyerang tanaman jagung di Indonesia sejak 2019. Daya jelajah yang luas dan kemampuan reproduksinya yang tinggi dapat mempercepat terjadinya penyebaran serta menaikkan tingkat serangan pada tanaman inangnya. Penelitian bertujuan untuk memperoleh informasi mengenai gejala serangan, insidensi serangan, populasi, intensitas serangan dan parasitoid utama yang berpotensi sebagai musuh alami untuk mengendalikannya. Enam Kecamatan di Kabupaten/ Kota Bogor dipilih sebagai target lokasi survei. Pengambilan data dilakukan dengan observasi langsung pada 30 tanaman contoh di beberapa kebun jagung dengan luasan minimal 0.25 Ha dan jarak minimal antar kebun 1 km. Sebanyak 30 ekor larva dan kelompok telur dikoleksi pada setiap kebun untuk mengetahui parasitoid yang muncul. Insidensi serangan S. frugiperda pada masing-masing wilayah berkisar antara 88,89 - 100%. Populasi larva S. frugiperda pada masing-masing wilayah bervariasi dengan rataan 7 - 21 ekor/kebun. Intensitas serangan yang ditimbulkan S. frugiperda berkisar antara 9,02 - 34,88%. Hasil identifikasi musuh alami menunjukkan bahwa parasitoid larva yang ditemukan adalah Euplectrus sp. (Hymenoptera: Eulophidae) dan Microplitis sp. (Hymenoptera: Braconidae), sedangkan parasitoid telur yang ditemukan adalah Telenomus remus (Hymenoptera: Scelionidae). Dari hasil pemeliharaan larva dan telur, diperoleh tingkat parasitisasi larva berkisar 10 - 30% dan parasitisasi telur berkisar 42,98 - 70,99%. Kedua parasitoid berpotensi untuk dijadikan sebagai agen pengendalian hayati S. frugiperda.

Abstract. Rahayu A, Rochman N, Nahraeni W, Yuliawati. 2025. Effects of fermented cow urine on the growth and quality of katuk (Sauropus androgynus) accessions from West Java, Indonesia. Asian J Agric 9: 831-843. This study examined the growth, yield, and nutritional quality of katuk using local germplasm and natural nitrogen sources. The objective was to evaluate the performance of ten katuk accessions from West Java, Indonesia, and to assess the potential of fermented cow urine as a supplementary nitrogen source relative to urea. A factorial completely randomized design with three replications was employed, consisting of ten accessions (Sarampad, Maleber1, Maleber2, Kadudampit1, Kadudampit2, Gegerbitung, Dramaga, Cinangneng1, Cinangneng2, and Katulampa) and six fertilizer compositions (0% cow urine + 100% Urea; 100% cow urine + 0% Urea; 75% cow urine + 25% Urea; 50% cow urine + 50% Urea; 25% cow urine +75% Urea; 0% cow urine + 0% Urea). Sarampad, Maleber1, and Maleber2 exhibited superior fresh and dry harvest weight, vitamin C, chlorophyll a and b content, while maintaining low nitrate accumulation. Plant height under 100% cow urine, shoot number and vitamin C under 25% cow urine + 75% urea, and chlorophyll a, b, and total chlorophyll under 50% cow urine + 50% Urea were higher than under 100% Urea, with superiority values of 14.7%, 19.0%, 20.2%, 14.6%, 18.2%, and 15.9%, respectively. These findings indicate that fermented cow urine may serve as a low-cost supplementary nitrogen source for katuk; however, its use as a full replacement for synthetic nitrogen fertilizer requires further validation under field conditions.
