Abstract

The process of producing starch film using the casting method required a significant amount of time to obtain the desired film product. Therefore, this study was conducted to reduce the production time required for the starch film. The study used five varieties of starch: bengkoang starch, talas starch, glutinous rice flour, wheat flour, and MOCAF flour. The process involved homogenizing the starch and glycerol mixture utilizing a stirrer, followed by heating using a microwave and a compression process to accelerate the evaporation of water in the starch film. For the final drying stage, samples that had gone through this process were dried using a cabinet dryer. The result showed that the developed method of starch film requires only 60 minutes of the time needed compared to conventional casting method, which usually takes 5-48 hours. Furthermore, it was observed that starch film production using glutinous rice flour resulted in the highest tensile strength.

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

Weeds are a significant constraint to crop production as they compete for vital resources and release allelochemicals that may hinder the growth of surrounding plants. This study investigated the allelopathic effects of plant litter from Kyllinga brevifolia, Eleusine indica, and Sphagneticola trilobata on the germination and early development of Lactuca sativa. Two bioassays were conducted: a sandwich method in the laboratory and a pot experiment in a greenhouse. Dried weed residues were applied at concentrations of 1%, 2%, 3%, and 4% to evaluate their impact on seed germination, root and shoot elongation, and biomass accumulation in lettuce. The results showed that all three species inhibited seed germination and seedling growth in a concentration-dependent manner. In the sandwich assay, germination rates at 4% residue concentration declined to 58.89% (K. brevifolia), 76.67% (E. indica), and 46.67% (S. trilobata), compared to 96.67% in the control. The strongest inhibition of radicle growth was observed in K. brevifolia (91.60%). In the pot experiment, both K. brevifolia and S. trilobata consistently reduced all measured growth parameters. At 4%, shoot length declined to 9.18 mm and 5.42 mm, and dry shoot weight decreased to 2.90 mg and 3.09 mg, respectively. In contrast, E. indica slightly increased shoot biomass at moderate concentrations, suggesting a potential stimulatory effect. These findings demonstrate that residues from these weeds possess strong allelopathic potential and could be explored as natural agents for environmentally friendly weed management.

Abstract. Chaniago N, Suliansyah I, Chaniago I, Rozen N. 2021. Morphological characteristics of local rice in Deli Serdang District, North Sumatra, Indonesia. Biodiversitas 23: 883-894. The preservation of local rice is essential to preventing genetic drain. In Deli Serdang District, North Sumatra, Indonesia, local rice is in great abundance. A total of 23 Deli Serdang local rice were collected and studied from coastal to highland areas. This study aims to determine the morphological characteristics of 23 local rice genotypes of Deli Serdang and to obtain superior characters to be developed into superior local varieties. A completely randomized design with three replicates was used in this study. Morphological characteristics of 23 local rice genotypes obtained various characters. The culm length was short to very long; culm diameter was thin to thick; the leaf-blade length was long to very long; leaf-blade width was intermediate to broad; culm number was low to high. The auricle, ligule, and collar were almost completely whitish, except for Sijambi yellowish-green and green, 2-cleft acute ligule shape. The harvest age was medium to deep. The grains were white, straw, gold, brown, brown spots, brown lines, and black. The pericarps were white, light brown, red, and black. Most of the organs indicated broad genetic variability having the opportunity to be developed into superior local varieties. All local rice was scattered into five groups based on morphological markers with a similarity of 32.12%.

Abstract. Chaniago I, Yulistriani, Umami IM, Bukhari ZZ. 2023. Soil macrofauna diversity and weed dynamics in response to different methods of weed control in smallholder rubber farming. Biodiversitas 24: 3106-3113. Weeds interference in rubber farmland may reduce latex yield. Farmers apply herbicides to control weeds. However, the herbicide not only controls weed but also affects the presence of soil macrofauna. A study has been conducted to determine the effect of different method of weed control on soil macrofauna and weeds at smallholder rubber farming at Pulau Punjung, Dharmasraya District, West Sumatra, Indonesia. The experiment was conducted in a completely randomized block design with 6 treatments and 4 pseudo-replications. Treatment was mechanical control, without weed control, and 4 doses of herbicide glyphosate+metsulfuron-methyl (1.5 L ha-1 + 15 g ha-1, 2 L ha-1 + 15 g ha-1, 2.5 L ha-1 + 15 g ha-1, 3 L ha-1 + 15 g ha-1) with 400 L ha-1 of volume. Pitfall traps were used to collect the soil macrofauna. Data were analysis with ANOVA for weed and soil macrofauna in response to different methods of weed control. Results demonstrated that the application of glyphosate+metsulfuron-methyl herbicide significantly suppressed weeds higher than that of other methods of weed control (p<0.05). Para grass (Brachiaria mutica (Forssk.) Stapf) was the most dominant weed but has been affected most by 3 L ha-1 + 15 g ha-1 herbicide mixture. Soil macrofauna of the order Hemiptera was affected most by the application of herbicide with a total reduction of 71.58% of number of individuals at 12 weeks after application of herbicide. In general, different weed control methods resulted in varied numbers of orders and individuals of the soil macrofauna.
