Abstract

Kenagarian (West Sumatra traditional village) Andaleh is located at the base of Mount Marapi in Batipuh Tanah Datar District, West Sumatra. The main livelihoods of the population are farming by planting rice, vegetable crops, ornamental plants, and cinnamon. In general, farmers in this location increase the yield of vegetables (onion) using artificial fertilizers. Sometimes it requires limited chemical fertilizer, difficult to obtain and expensive. Of course, this will burden farmers in the production of onion is a daily necessity of the community. At this location, there are many titonia plants and agricultural waste. The solution given is agricultural waste and plant processing into compost. Compost can increase growth and yield of onion bulbs. The objectives to be achieved in Community Service and Empowerment Program (KKN-PPM) activities are 1) Making compost using straw and agricultural waste and its application as organic fertilizer when mapping the red plotters, 2) Applying agricultural waste compost in the cultivation of onion 3) Processing the onion bulbs into the fried onion. The methods applied were debriefing students, counseling, training and demonstration plots with farmers. Activities that have been carried out are counseling about good onion cultivation, counseling about the benefits of organic fertilizer (compost) to 1) improve soil improvement and sources of nutrients for plants. 2) training to make compost from straw and agricultural waste using Effective Microorganism EM-4, 3) supporting compost application in onion cultivation in farmers' fields and 4) processing of fried onion.

Abstract

The conversion of fertile land into industrial areas and construction development has contributed to the decline of rice production in Indonesia. Therefore, it is necessary to expand the rice fields to the sub-optimal land, i.e. lands with high levels of Fe and Al and low soil pH. One of the solutions that can potentially solve the problem is choosing varieties of rice that can adapt to the suboptimal land environment; the rice varieties can be obtained by estimating rice genetic parameters and selecting the optimal planting methods. One method that can potentially improve rice yield is “System of Rice Intensification”, or SRI method. Our study was conducted in the rice fields on suboptimal land at Pasar Ambacang, Kuranji District, Padang, Sumatra, from December 2019 to April 2020. The aims of the experiment are to determine the genetic parameters and responses of the three rice varieties to suboptimal land using the SRI method. A complete randomized design with four replications was used to set up the experiment using three varieties of rice, i.e. “Batang Piaman”, “Bujang Marantau”, and “IPB3S”. Based on the plant growth measurement and analysis of the genetic parameters, we found that the plant growth characters, particularly height and panicles length, had high heritability and genetic progression values.

Abstract

Rice stands as an important staple crop in Indonesia and Asia, prompting endeavors to enhance its production. One such technology, aimed at intensifying rice cultivation, involves optimizing plant density utilizing the "jajar legowo" system. This research was conducted within community rice fields located in Pasar Ambacang, Kuranji District, Padang City, West Sumatra, Indonesia, spanning from February 2020 to June 2020. The primary objective of this study was to assess the potential of the jajar legowo planting system, in conjunction with varying dosages of kieserite, to increase lowland rice yields. The study employed a two-factor experiment in a completely randomized design. The first factor is the jajar legowo types: A (25 cm x 12.5 cm x 50 cm) and B (25 cm x 25 cm x 50 cm). The second factor involved different kieserite dosages, comprising three levels (0, 150, 300 kg.ha-1). Each treatment combination was replicated four times. Our investigation unveiled that rice panicle length reached 27.20 cm under the influence of jajar legowo type A with a kieserite dosage of 150 kg.ha-1. Conversely, with the application of jajar legowo type B alongside a kieserite dose of 300 kg.ha-1, the rice panicle length increased to 27.88 cm. The highest yield was obtained with jajar legowo type A at a dose of 300 kg.ha-1, producing 5.35 tons.ha-1. It is recommended to implement the jajar legowo type A cropping pattern with the addition of 150 kg.ha-1 of kieserite, or jajar legowo type B with the addition of 300 kg.ha-1 of kieserite.

Abstract

Titan arum (Amorphophallus titanum (Becc.)) was an endemic flora found only on the island of Sumatra, listed as endangered and possessing the largest flower among 170 species of Amorphophallus. Conservation activities could benefit from the use of plant propagation through cuttings. The success of cuttings was determined by the concentration of plant growth regulators (PGR) to induce the formation of roots, corms, and shoots, making the study of PGR concentration important. This study aimed to find the best IBA concentration to induce roots, corms, and shoots in A. titanum. The research was conducted from February to October 2023. The study was designed based on a completely randomized design with treatments of IBA concentration consisting of 5 levels: 0, 5, 10, 15, and 20 mg L-1. The results showed that an IBA concentration of 15 mg L-1 produced the best survival percentage (100%), rooting percentage (93.33%), corm formation percentage (93.33%), shoot formation percentage (76.67%), and an average of 1.20 shoots per cutting on A. titanum petiole cuttings.

Abstract

One of the factors hindering the development of upland rice cultivation among annual crops is the limited number of shade-tolerant upland rice varieties. It is very important to assemble shade-tolerant upland rice varieties with high yields. The purpose of the study was to determine the effect of shade on the growth and productivity of five genotypes of upland rice. This research was carried out in the experimental garden of the Faculty of Agriculture, the Islamic University of North Sumatra with an altitude of 25 m above sea level, from June to December 2020. The research design was split-plot and repeated three times. The main plot of shade treatment consisted of two levels, namely no shade (0%) and shade treatment (70%). The sub-plots were five genotypes of upland rice in Deli Serdang and two shade-tolerant varieties. Shade treatment affected the growth and productivity of five genotypes of upland rice in Deli Serdang District (Sialus, Arias, Ramos Merah, Silayur, and Sirabut) and two shade-tolerant varieties (Rindang 1 and 2). Two genotypes of upland rice were obtained, namely Silayur and Sirabut which were more shade tolerant, based on flowering age, harvest age, and grain weight per clump. When compared with Rindang 1 and 2 varieties, the two genotypes of upland rice were the same or more tolerant.

Abstract

The present study aims to analyse the effect of variations in the amount of Mocaf starch and glycerol concentration on the physical and mechanical characteristics of the bioplastics produced. The method employed in this study was casting. The experimental design employed in this study was a completely randomised two-factor design, namely the amount of starch (4, 5, 6 and 7 g) and glycerol concentration (20, 30, and 40% w/w based on starch). The data were analysed using analysis of variance (ANOVA) at a significance level of 5%; when significant differences were identified, Duncan's test was used to follow up. The findings indicated that the quantity of mocaf starch and glycerol concentration exerted a substantial influence on the physical and mechanical properties of bioplastics. An increase in the amount of starch led to an increase in density, thickness, and, most significantly, tensile strength. Conversely, an increase in glycerol concentration did not affect the density, but increased the thickness and elongation, while decreased the tensile strength. The interaction of these two factors also had a significant effect on thickness, tensile strength, and elongation.

Abstract

Padi merupakan komoditas pangan penting di Indonesia. Intensifikasi pertanian harus diupayakan dengan mengombinasikan metode tanam dan pemberian pupuk yang tepat. System of Rice Intensification (SRI) merupakan salah satu metode tanam yang tepat karena memaksimalkan penggunaan udara, tanah, dan tanaman. Selain itu, pemberian pupuk kiserit dan pupuk hayati perlu dikaji lebih lanjut untuk melihat pengaruhnya terhadap pertumbuhan dan hasil tanaman padi. Penelitian ini bertujuan untuk melihat interaksi dan menentukan dosis optimal pupuk kiserit dan pupuk hayati dalam meningkatkan pertumbuhan dan hasil padi pada metode SRI. Percobaan telah dilaksanakan pada bulan Februari hingga Juli 2025 di Nagari Singgalang, Kabupaten Tanah Datar, Sumatera Barat. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) dua faktor. Faktor pertama adalah dosis pupuk kiserit (75, 150, dan 225 kg/ha), sedangkan faktor kedua adalah dosis pupuk hayati (0, 40, dan 80 kg/ha). Setiap kombinasi perlakuan diulang sebanyak 3 kali, sehingga terdapat 27 unit satuan percobaan. Data dianalisis menggunakan analisis sidik ragam (ANOVA) pada taraf 5%. Apabila hasil uji F berbeda nyata, maka dilanjutkan dengan uji Duncan's Multiple Range Test (DMRT) pada taraf nyata 5%. Hasil penelitian menunjukkan adanya interaksi yang signifikan antara pupuk kiserit dan pupuk terhadap parameter hayati tinggi tanaman, panjang akar, volume akar, dan bobot kering total. Kombinasi dosis 75 kg/ha kiserit dan 40 kg/ha pupuk hayati menghasilkan pertumbuhan yang terbaik. Pemberian pupuk kiserit dan pupul hayati memberikan pengaruh yang berbeda tidak nyata pada hasil tanaman padi.
