Abstract

Mbawi merupakan salah satu desa di Kabupaten Dompu, NTB yang memiliki potensi perikanan berlimpah, baik dari laut maupun tambak. Namun demikian, potensi tersebut belum dioptimalkan oleh masyarakat, hasil tangkapan ikan masih diperjualbelikan dalam bentuk segar dengan harga murah. Jadi, potensi yang dimiliki belum mampu menyejahterakan masyarakat. Oleh karena itu, akan dilakukan pendampingan terutama kepada ibu rumah tangga yang banyak mempunyai waktu luang untuk meningkatkan nilai jual produk ikan dengan mengolahnya menjadi abon. Juga mitra yang lain yaitu karang taruna yang selama ini belum banyak berkegiatan, yang diharapkan dapat membantu para ibu untuk pengembangan usaha. Ikan yang dipilih adalah ikan bandeng yang jumlah produksinya terbanyak, dan diolah menjadi abon karena produk ini awet dalam waktu yang cukup lama. Pelatihan yang diberikan sudah menggunakan teknologi tepat guna seperti mesin cold storage, mesin peniris minyak, mesin penggoreng, dan mesin pencacah daging ikan. Evaluasi hasil pelatihan menunjukkan bahwa 91,3% mitra mengalami peningkatan pengetahuan  adanya peningkatan jumlah warga yang faham tentang gizi yang terkandung dalam ikan bandeng, dan sebanyak 90,9% mitra mengalami peningkatan kemampuan membuat abon ikan bandeng. Selain itu, peserta sangat paham dengan pelatihan yang telah dilakukan diberikan, baik materi maupun praktiknya. Analisis Harga menunjukan bahwa ikan bandeng segar 5 kg seharga Rp. 140.000,- setelah diolah menjadi abon memperoleh keuntungan sebesar Rp. 206729,05,-

Abstract

Selfing is the initial step to form hybrid varieties. Selfing has been carried out for four generations and 29 S4 lines have been obtained. All lines have been tested for their tolerance level to drought stress in dry land. The purpose of the study was to determine the tolerance level of S4 lines of corn plants to drought stress in dry land. Experimental methods with field trials were used for the test. And the correlation between characters and ISC values. The design used was a randomized block design at each stress level. Determination of the tolerance level used the observation parameter of the results (dry seed weight per plant) under mild stress conditions and normal conditions. The tolerance level to drought stress was measured from the Stress Sensitivity Index (ISC) value. The results showed that three S4 lines were tolerant to drought stress, namely lines S4.7, S4.15 and S4.24. Nine S4 lines have moderately tolerant category, namely lines S4.1, S4.3, S4.8, S4.12, S4.13, S4.14, S4.21, S4.26 and S4.29; the rest are classified as sensitive. The yield have a high negative correlation with the ISC value; the weight of dry cobs harvested per plant has a moderate negative correlation. The three tolerant lines can be used for the formation of S5 lines.

Dengan jumlah perlakuan 25 perlakuan terdiri dari 22 genotipe tanaman mutan dan 3 tanaman pembanding. Hasil pengamatan dianalisis menggunakan analisis ragam dengan taraf 5%. Kemudian perlakuan yang berbeda nyata diuji lanjut menggunakan uji Beda Nyata Jujur (BNT) pada taraf 5%. Hasil penelitian menunjukkan bahwa perlakuan iradiasi sinar gamma 300 Gy pada generasi M2 padi beras merah (G16) menyebabkan perbedaan karakter pada masing-masing genotipe diantaranya pada karakter Jumlah anakan nonproduktif, jumlah gabah hampa permalai, panjang malai, berat gabah berisi, jumlah anakan total, jumlah gabah berisi dan berat gabah hampa. Karakter yang paling baik pada tanaman mutan GM20, GM26, GM27, GM30, dan GM52. Sedangkan heritabilitas tanaman mutan generasi M2 padi beras merah (G16) hasil iradiasi sinar gamma 300 Gy tergolong Nilai heritabilitas tinggi diperoleh pada karakter tinggi tanaman, jumlah anakan nonproduktif, panjang malai, jumlah gabah isi permalai, jumlah gabah hampa permalai, berat 100 butir, berat gabah berisi, berat gabah hampa, dan berat gabah per rumpun. Sedangkan heritabilitas sedang diperoleh pada karakter umur panen dan jumlah anakan total dan heritabilitas rendah diperoleh pada karakter umur berbunga, jumlah anakan produktif.

Abstract

Radish (Raphanus sativus L.) is a horticultural crop with potential for urban farming, but its performance is influenced by growing media characteristics and nutrient availability. This study aimed to analyze the effects of growing media, KNO₃ fertilizer doses, and their interaction on the growth and yield of French Breakfast radish grown in polybags. The study was conducted from May to July 2026 using a factorial Completely Randomized Design with two growing media, namely soil + rice husk and soil + sand, and four KNO₃ doses (0, 0.75, 1.50, and 2.25 g polybag⁻¹), with four replications. Data were analyzed using analysis of variance followed by the 5% HSD test. The results showed a significant interaction between growing media and KNO₃ dose on leaf number growth rate and leaf number at 28 days after planting (DAP). The combination of soil + rice husk and 0.75 g KNO₃ polybag⁻¹ produced the highest values, at 0.21 leaves day⁻¹ and 7.75 leaves, respectively. Growing media significantly affected leaf number at 14 DAP and shoot-to-root ratio, while KNO₃ significantly affected fresh plant weight based on ANOVA. No significant effects were observed on tuber yield components. These findings imply that soil + rice husk combined with 0.75 g KNO₃ polybag⁻¹ may support vegetative growth, but cannot yet be recommended as an optimum treatment for increasing tuber yield.

Abstract

Drought is a major constraint to rice production in upland environments; therefore, identifying genotypes with promising performance under these conditions is an important breeding objective. This study evaluated the agronomic performance of M6 brown rice mutant genotypes induced by gamma irradiation under field upland conditions. The available dataset comprised 15 entries (13 mutant lines and two check varieties) evaluated in a randomized complete block design with three replications. Ten quantitative traits were assessed, including days to flowering and harvest, plant height, total and productive tiller number, panicle length, leaf angle, filled and total grains per panicle, and 100-grain weight. Data were analyzed using analysis of variance at the 5% significance level; post-hoc comparisons were considered where appropriate. Significant genotypic effects were detected for total tiller number (P = 0.039), productive tiller number (P = 0.002), leaf angle (P = 0.006), days to flowering (P = 0.027), filled grains per panicle (P = 0.005), total grains per panicle (P < 0.001), and 100-grain weight (P < 0.001). Plant height, panicle length, and days to harvest did not differ significantly among entries. G27 1-20-19 flowered earliest (83 days) and combined a relatively high number of filled grains with a high leaf-angle value, whereas G27 1-20-6 had high numbers of filled and total grains. These entries warrant further evaluation across environments and seasons. The findings indicate agronomic potential under the tested conditions but do not, by themselves, establish drought tolerance.

Abstract

The mealybug Paracoccus marginatus is a major pest of crystal guava (Psidium guajava L.), often associated with honeydew-seeking ants. However, these associations in the dryland areas of West Nusa Tenggara, Indonesia, remain poorly documented. This study identified ant taxa associated with mealybug colonies and analysed relationships among ant population, mealybug population, and attack intensity. An observational study was conducted in Gerung, West Lombok, from May to June 2026. Twenty infested trees in four blocks were observed weekly for five weeks. Ants and mealybugs were counted on four canopy sides, attack intensity was scored on a 0–4 scale, and ants were identified morphologically. Pearson correlation and diversity indices were used for analysis. Seven ant taxa from five subfamilies were identified, including four active or opportunistic mutualists, one facultative mutualist, and two predatory or incidental taxa. Mealybug and ant populations declined concurrently by approximately 53% and 52%, respectively, and were strongly correlated (r = 0.886, p < 0.001). Ant and mealybug populations were positively correlated with attack intensity (r = 0.659 and 0.871, respectively). Although these patterns are consistent with potential mutualism, the observational design does not establish causality. Ant management, including trunk barriers, may be considered in integrated pest management, pending further evaluation.
