Abstract

Indonesia mempunyai beragam sumberdaya pangan sehat yang sangat berpotensi untuk dikembangkan, salah satunya ialah Hanjeli. Diketahui bahwa tanaman serealia ini memiliki bentuk fenotipik yang beragam serta adaptif untuk tumbuh pada berbagai kondisi lingkungan. Beragamnya karakteristik antar genotipe hanjeli akan berpengaruh terhadap mutu biji baik secara kualitas maupun kuantitas. Cara membedakan karakter khas dari masing-masing genotipe hanjeli, diperlukan pengamatan dan pengukuran secara detail salah satunya pada organ perkembangbiakan yakni biji. Penelitian ini bertujuan untuk mengevaluasi mutu fisik biji hanjeli lokal Sumatera Barat sebagai langkah untuk mendapatkan genotipe yang potensial dari segi kuantitas maupun kualitas. Enam aksesi hanjeli yang digunakan meliputi PTA-1, KKD-3, PH-4, BTA-2, GT-2, dan TJR-2. Percobaan ini menggunakan Rancangan Acak Kelompok dengan 3 ulangan sehingga didapatkan 18 satuan percobaan. Disimpulkan berdasarkan dimensi aksialnya (panjang, lebar dan tebal biji) menunjukkan bahwa aksesi dengan kode BTA-2 dan KKD-3 memiliki bentuk dan ukuran biji terbesar dan aksesi dengan kode GT-2 sebagai aksesi dengan bentuk dan ukuran biji terkecil. Pada pengamatan tingkat kekerasan biji, ketebalan epicarp, bobot 100 biji pecah kulit serta rendemen biji pecah kulit aksesi dengan kode PH-4 menunjukkan sebagai genotipe terbaik.

Abstract

Sunflower is a commodity that has the potential to be developed as a raw material for producing vegetable oil because it contains high levels of vitamin E. This plant has wide adaptability and requires areas with full sun. However, only certain varieties are able to grow and develop optimally in various agroecosystems. So we need information regarding the suitability of varieties with specific conditions of a location. This study aims to obtain information about varieties that are adaptive to new openings in the highlands of Alahan Panjang, Solok Regency, West Sumatra (1,620 masl) based on growth and yields achieved. The experiment was designed using a Randomized Block Design (RAK) with 3 groups and 5 levels of treatment, namely sunflower varieties. The varieties include IPB BM 1, Ring of fire, Russian Mammoth, Hoppy Black Dye, Black Russian, and Kanigara. The varieties of Russian Mammoth, Ring of Fire, and Hopi Black Dye have better growth when viewed from their adaptability in the research location. Meanwhile, based on the weight of seeds/plant, the percentage of pithy seeds, and the weight of 100 grains the Russian mammoth variety had the best results.

Abstract

Indonesia dikenal sebagai wilayah megabiodiversity, hal ini disebabkan karena menyimpan keanekaragaman spesies flora serta fauna yang melimpah. Kuantitas dari biodiversitas ini bersifat fluktuatif, kenaikan terjadi jika ditemukan spesies-spesies baru di alam, dan penurunan bisa disebabkan akibat terjadinya kepunahan. Sumatera Barat merupakan daerah dengan tingkat sumber keanekaragaman hayati yang tinggi. Namun sampai saat ini potret biodiversitas provinsi Sumatera Barat tidak dideskripsikan secara menyeluruh dan lengkap, tercatat belum semua daerah memiliki basis data kanekaragaman hayati. Salah satu pangan lokal alternatif yang belum teridentifikasi secara menyeluruh ialah tanaman hanjeli dengan nama ilmiah Coix lacrima-jobi L. Tujuan dari review artikel ini yakni untuk mengumpulkan informasi-informasi perihal kondisi keanekaragaman tanaman hanjeli yang ada di Sumatera Barat. Ditemukan bahwa hanjeli mampu untuk tumbuh pada dataran rendah hingga dataran tinggi serta mampu adaptif pada bermacam kondisi ekosistem, antara lain pada lahan kering serta zona di sekitar sumber aliran air. Diketahui bahwa terdapat keanekaragaman tanaman hanjeli yang ditemukan di provinsi Sumatera Barat, hal ini terlihat dari keragaman fenotipik yang ditampilkan baik berupa karakter kualitatif maupun kuantitif pada batang, daun, bunga, serta biji.

Abstract

Bunga matahari termasuk salah satu jenis komoditi pertanian yang mempunyai potensi besar untuk dikembangkan. Hal ini bukan tanpa alasan karena setiap bagian dari bunga matahari dapat digunakan untuk makanan, pakan ternak, bahan baku industri, kecantikan dan obat-obatan. Saat ini pengembangan bunga matahari telah bergeser ke penggunaan lahan marginal seperti lahan pesisir namun memiliki banyak permasalahan. Untuk itu perlu dilakukan berbagai inovasi dan penerapan teknologi. Salah satunya adalah penggunaan mikoriza dan kompos maggot. Tujuan penelitian adalah untuk mengetahui respon pertumbuhan bunga matahari di lahan pesisir pantai pada aplikasi beberapa dosis mikoriza dan kompos maggot. Penelitian ini dilakukan dengan rancangan acak kelompok secara faktorial dengan 4 taraf pada masing-masing perlakuan dan diulang sebanyak 3 kali. Hasil penelitian menunjukkan bahwa semakin tinggi dosis mikoriza dan dosis kompos maggot yang diberikan akan berbanding lurus terhadap pertumbuhan bunga matahari pada lahan pesisir pantai.

Abstract

Utilizing idle land as agricultural land is one option that can be pursued to support national food security and independence. Indonesia has various types of alternative food commodities that have the potential to be developed on nutrient-poor land, one of which is hanjeli. Technical cultivation is needed to increase the growth and yield of hanjeli on sub-optimal land. This study aims to determine the best planting distance to increase hanjeli production on idle land. The research was conducted from October 2020 - March 2021 in Limau Manis, Padang City, West Sumatra. The materials used in this study were rice cultivar hanjeli seeds, manure (20 tons/ha) and NPK fertilizer (200 kg/ha). The experimental design used was Randomized Group Design with 3 groups and consisted of 8 plant spacing treatments (40 x 40 cm, 50 x 40 cm, 50 x 50, 50 x 60 cm, 50 x 70 cm, 50 x 80 cm, 50 x 90 cm, and 50 x 100 cm). Observation data were analyzed statistically to determine the influential treatment using the F test at the 5% level and significantly different data were tested using the Duncan’s Multiple Range Test at the 5% level. It was concluded that the spacing of 50 x 70 cm, 50 x 80 cm, 50 x 90 cm and 50 x 100 cm gave the best effect on the number of total tillers/plant, the number of productive tillers/plant, the number of seeds/plant, the percentage of filled seeds, the weight of filled seeds/plant. As for productivity, the spacing of 50 x 80 cm gave the best results.

Abstract

Farmers commonly use inorganic fertilizers such as urea, rock phosphate, and NPK in crop cultivation. Continuous use of these inorganic fertilizers can degrade the quality of the growing medium and increase production costs. Inorganic fertilizers are also relatively expensive. One way to address this issue is by utilizing allelochemical compounds as Liquid Organic Fertilizers (LOF) for plant cultivation. Applying fertilizers in liquid form is more easily absorbed by plants because they are already dissolved and readily available. Babandotan liquid organic fertilizer contains essential nutrients such as nitrogen (N), phosphorus (P), and potassium (K). These elements play a crucial role in stimulating vegetative growth, promoting root development, and strengthening the plant's overall health. The objective of this activity is to enhance the knowledge of the members of the Banda Langik Women Farmers Group about liquid organic fertilizer made from Babandotan weed, as well as to fulfill the Higher Education Tri Dharma for lecturers in the Agrotechnology Program at the Faculty of Agriculture, Andalas University. This community service activity was conducted at the Banda Langik Women Farmers Group, located at Jl. Ekora RT01/RW07 Sungai Bangek, Balai Gadang Village, Koto Tangah District, Padang City, in May-June 2022. The activities performed included preparation, socialization, closing, and reporting. Based on the results of the activity, several key points were identified, including that the community service program was conducted according to the needs of the Women Farmers Group, the group was satisfied and found the service beneficial for their development in the future, and the group members were committed to using LOF in their cultivation areas.

Abstract

The Taruko Saiyo Farmer Group is a community-based farmer initiative that comprises and grows based on harmony, warmth, and shared interests in utilizing agricultural resources to collaborate in improving the productivity of agricultural enterprises, especially in increasing rice production. Given the strong desire of the members of the Taruko Saiyo farmer group to tackle the issues arising from climate conditions and feeling the need to be accompanied due to a lack of science and technology knowledge regarding climate change mitigation and adaptation, it is appropriate as a partner to support the desires of these farmers and to provide guidance until they can master the science and technology and become an independent farmer group. The purpose of this project is: 1) To help farmers understand climate information and forecasts to support agricultural activities, particularly for planting season decisions and the right technical cultivation strategies as an effort to increase product quantity, 2) To enhance science and technology knowledge and management skills of farmers in managing agricultural waste as support for farming activities, as well as to form an awareness of climate conditions. This community service activity is carried out from June to September 2024. Some of the agendas in this climate field school program include socialization, training, application of science and technology, mentoring, and evaluation. Based on the evaluation results, around 90% of the partner members felt an increase of about ?80% in understanding, management, science and technology implementation, and production quantity. With ongoing support and active participation from various parties, it is hoped that this program can become a model for sustainable agriculture development.

Abstract

Indonesia has the potential to develop alternative food sources, one of the cereal crops that has the potential and prospects to be developed is job's tears (Coix lacrima-jobi L.). Efforts that can be made to increase job's tears production are variety selection, proper cultivation techniques, and favorable environmental conditions. Fertilization is one of the most important factors that need to be considered in plant cultivation techniques. This research was conducted in Padang city, West Sumatera. The research was factorial in the form of a complete random design. The job’s tears cultivars used in this riset were Pulut and Batu. The purpose of this study was to determine the effect of NPK fertilizer on growth and yields of two job’s tears cultivars. NPK fertilizer dosage treatment in this study consisted of : 0 kg/hectare, 100 kg/hectare, 200 kg/hectare, and 300 kg/hectare. The results showed that there was no interaction between NPK fertilizer and two job’s tears cultivars. Pulut showed the highest mean values on growth variables (plant height, leaf length, and stem diameter), but Batu showed the highest mean values on yield variables (seed weight / plant). While the best dose of NPK fertilizer to increase growth and yield is 300 kg/hectare.
