Jurnal Ilmiah Pertanian https://journal.unilak.ac.id/index.php/jip <p>Jurnal Ilmiah Pertanian (JIP) is an open-access journal that publishes original research articles on agricultural advances and various other agricultural resources at the local level to increase global awareness.. <br><br>Initially, the Jurnal Ilmiah Pertanian (JIP) was published twice yearly, every February and August. However, starting with Volume 19, 2022, Jurnal Ilmiah Pertanian (JIP) is a triannual journal published every March, July, and Dec.&nbsp; It is published electronically via the journal website.

This study aimed to explore the potential of winged-bean meal subjected to different heating methods, namely oven (110 °C for 30 minutes) and autoclave (121 °C for 30 minutes), based on proximate analysis and trypsin activity. The study applied three treatments with four replications: oven heating (O), autoclave heating (A), and control (without heating, E). All data were analyzed using analysis of variance and Duncan’s multiple range test to determine the best treatment. Data were also compared to the nutrient requirements of several cultured freshwater fish in Indonesia. Heating treatments improved <em>in vitro</em> trypsin activity (1300 units/O and 1135 units/A vs. 835 units) but reduced protein (29.05±1.96%/A and 31.73±1.52%/O vs. 35.17±0.38%) and moisture contents. Additionally, the O treatment met the standards for aquafeed protein content (27-45%) and potentially fulfilled the protein requirements for catfish (25-40%), Nile tilapia (30-35%), and Java barb (30-32%). Therefore, oven heating presents a viable candidate as an alternative plant-based aquafeed ingredient. Nevertheless, the in vivo application of winged-bean meal as an aquafeed ingredient should be further evaluated to determine whether heating treatment effectively enhances digestive activity, nutrient retention, and growth performance in target fish species.</p> Shobrina Silmi Qori Tartila Tholibah Mujtahidah Muh.

The known sorghum varieties from South Sulawesi include Batara Tojeng Eja, Batara Tojeng Bae, and local sorghum from Jeneponto. In Bulukumba Regency, South Sulawesi Province, Indonesia, local farmers traditionally cultivate local sorghum alongside maize. This study aims to gather information on the agronomic traits, morphological characteristics, nutritional composition, and phytochemical content of local sorghum from Tritiro village, Bulukumba Regency. Agronomic and morphological traits were analyzed through observations of growth and phenotypic features of the leaves, stems, roots, panicles, and seeds of sorghum. Nutritional composition was measured quantitatively, while phytochemical screening was conducted both qualitatively and quantitatively. The results show that local Tritiro sorghum has medium plant height, small stem diameter, medium panicle length, loose panicle shape, and brown seeds. Nutritional analysis revealed that local Tritiro sorghum contains 10.11% protein, 0.19% fat, 86.73% carbohydrates, 68.97% starch, and 9.43 mg g⁻¹ tannins. Local Tritiro sorghum has higher carbohydrate, protein, and fiber content compared to other sorghum varieties from South Sulawesi and exhibits higher tannin content. These findings highlight the potential of local Tritiro sorghum as a valuable nutritional resource and its suitability for cultivation in the region, contributing to food security and sustainable agricultural practices.</p> Maisya Zahra Al Banna Widiastini Arifuddin Copyright (c) 2024 Jurnal Ilmiah Pertanian https://creativecommons.org/licenses/by/4.0 2024-07-20 2024-07-20 21 2 10.31849/jip.v21i2.16672 Water balance optimization for strategic planting patterns and calendars in paddy (Oryza sativa L.) cultivation in rainfed regions https://journal.unilak.ac.id/index.php/jip/article/view/19958 <p>Paddy (<em>Oryza sativa</em> L.) is a staple food crop in Indonesia that requires more water compared to other annual crops. Cultivating paddy in rainfed areas necessitates effective water management to prevent crop failure, making it essential to calculate water balance, planting patterns, and planting calendars. This study aims to analyze the water balance in relation to planting patterns and calendars based on water availability in the field. The research was conducted in Cukilan Village, Semarang Regency, Indonesia. A descriptive quantitative method using Cropwat 8.0 was employed to determine water balance, planting patterns, and planting calendars. The results indicate that from November to April, there is a water surplus, while from May to October, there is a water deficit. Planting can be conducted once per growing season with two possible periods: November-March or December-April. During Period I (November-March), the water requirement is 640.7 mm with effective rainfall of 1031.2 mm. In Period II (December-April), the water requirement is 638 mm with effective rainfall of 935.7 mm. Planting should begin in November or December, with harvest in March or April. From May to October, the land remains fallow due to insufficient water availability. These findings are valuable for enhancing the effectiveness of paddy cultivation in rainfed areas, assisting farmers with planting planning, and minimizing the risk of crop failure due to water scarcity.</p> Feri Yoga Bistok Hasiholan Simanjuntak Copyright (c) 2024 Jurnal Ilmiah Pertanian https://creativecommons.org/licenses/by/4.0 2024-07-24 2024-07-24 21 2 10.31849/jip.v21i2.19958
