Abstract

Expansion of planting areas by utilizing sub-optimal land and the use of superior varieties is one of the alternatives in increasing soybean production in Indonesia. Therefore, this study aims to analyze the growth of three soybean varieties on Ultisol land in the Experimental Garden of the Faculty of Agriculture, Andalas University. This activity was conducted from September to November of 2022. The soybean varieties used in this study were Dena 1, Devon 1, and Demas 1. This research was designed using a Randomized Group Design with 1 factor, namely the type of variety with 3 groups of replications. The observation results of each treatment were analyzed statistically. If F count is greater than F table, then continued with Tukey's Further Test at the 5% level. It was concluded that some of the observed characters of the three soybean varieties showed that there were significant differences in growth in the observation of plant height and leaf area index. While in the observation of plant growth rate and the ratio of crown: root there was no significant difference between the tested varieties.

Abstract

Metode pengelompokan zona iklim yang kompatibel untuk dimanfaatkan dalam bidang agraria ialah klasifikasi menurut Oldeman. Kondisi beberapa tahun terakhir curah hujan pada beberapa wilayah cenderung berubah akibat perubahan iklim, oleh sebab itu diperlukan data yang aktual dan akurat sebagai landasan pembuatan klasifikasi zona agroklimat. Seiring perkembangan teknologi, penginderaan jarak jauh (satelit) dapat dijadikan sebagai salah satu pilihan untuk mendapatkan data curah hujan yang representatif. Tujuan dari pelaksanaan penelitian ini adalah untuk mengidentifikasi serta memetakan zona agroklimat Kabupaten Pesisir Selatan, Sumatera Barat tahun 1981 - 2023 berdasarkan klasifikasi Oldeman berdasarkan sumber data dari Climate Hazards Group Infrared Precipitation with Station (CHIRPS). Penelitian dilaksanakan pada bulan Juli - September 2024. Pendekatan kuantitatif digunakan untuk memetakan zona iklim pertanian di Kabupaten Pesisir Selatan berdasarkan klasifikasi Oldeman. Pemetaan ini berbasis pada informasi curah hujan bulanan yang didapatkan dari CHIRPS, serta pemanfaatan shapefile administrasi Provinsi Sumatera Barat. Periode data curah hujan CHIRPS yang dimanfaatkan ialah pada tahun 1981 - 1996 dan 2008 - 2023. Diketahui bahwa wilayah yang mengalami pergeseran zona iklim dari tipe B1 menjadi A1 adalah kecamatan Ranah Ampek Hulu Tapan, Lunang, Pancung Soal dan Silaut. Wilayah yang mengalami pergeseran zona iklim dari tipe D1 menjadi D2 ialah Kecamatan IV Nagari Bayang Utara, sedangkan wilayah yang mengalami pergeseran dari tipe D2 menjadi tipe D1 adalah Kecamatan Ranah Pesisir dan Linggo Sari Baganti. Disamping itu, berdasarkan hasil pemetaan klasifikasi iklim Oldeman Kabupaten Pesisir Selatan terbagi dalam empat zona agroklimat, yakni A1, B1, D1 dan D2.

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

Cocoa is one of Indonesia's flagship commodities that significantly contributes to the nation's economy. However, recently, the fame of cocoa has been declining due to various issues affecting its cultivation, from upstream to downstream. One of these issues is the use of low-quality cocoa seeds, adversely impacting long-term production. This condition affects the enthusiasm of the community in cocoa cultivation, leading to a decline in national cocoa production. Hence, there's a need for early anticipation by socializing cocoa planting to the younger generation, especially those around the University Andalas campus in Padang. The objective of this activity is to impart knowledge about cocoa plants and the cocoa planting process to the younger generation around the University Andalas to support sustainable cocoa farming. The event took place in Sungai Balang, Pauh Kota Padang. The method employed was structured socialization to the younger generation at the University Andalas Campus. The activity's outcomes were evaluated through questionnaires. The results indicated high enthusiasm among the participants, with 87% expressing high satisfaction with the conducted activities, and 93% hoping for the sustainability of these initiatives. These results demonstrate an increased understanding among the younger generation at the University Andalas about cocoa plants, cocoa planting, and the entrepreneurial spirit based on cocoa planting. It's hoped that this initiative continues, supported by mentoring and guidance.

Abstract

Expansion of soybean cultivation by utilizing land beneath tree canopies and adjusting plant populations can be considered as an alternative to increase national soybean production. The objective of this research is to examine the influence of seed quantity per planting hole on the agronomics of soybean variety Dena 1 under different lighting conditions. This study was conducted from August to November 2023 at the Experimental Garden of the Faculty of Agriculture, Andalas University. The experimental design used was a Completely Randomized Design (CRD) with two factors and three replications. The first factor was lighting conditions, while the second factor was the quantity of seeds per planting hole. Soybean plants under unshaded conditions showed the best influence on plant height, stem diameter, as well as an increase in pod number and percentage of filled pods. The interaction between the treatment of seed quantity per planting hole and different lighting conditions influenced the seed weight per plot, where planting two seeds per planting hole under unshaded conditions yielded the best result at 280.56 g.
