Abstract

Karang Bangun Village is one of the centers for lowland rice production in Simalungun Regency, North Sumatra. The area of rice fields reaches 70% of the village area with good technical irrigation. However, the application of technology in the management of lowland rice in this village is still very conventional, and the knowledge of farmers about the new technology does not yet exist so that production only reaches 6 tons/ha. The purpose of this community service activity is to transfer the rice cultivation technology which is effective in increasing yields. The technologies are the application of the System of Rice Intensification (S.R.I) method, processing of straw waste into Bokashi organic fertilizer which can increase soil fertility, recognition of the symptoms of plant nutrient deficiency, and the use of plants as natural pesticides. Through assistance to farmers using a participatory approach in community service activities, the transfer of technology can run smoothly so that the use of irrigation water can be efficient, efficiently in using inorganic fertilizers, the use of inorganic pesticides is reduced and the productivity of farmers' land can be increased and by itself will improve the welfare of farmer.

Abstract

The objective of this study is to investigate the impact of oil palm bed ash at different doses on the growth and yield of black soybean plants (Glycine soja L.) in different types of soil. A Factorial Randomized Group Design (RAK) with two factors was used in this study. The first factor is the application of oil palm bed ash, a byproduct of burning palm fruit bunches. The second factor is the type of soil used in the experiment. The study's results indicate that andosol and alluvial soil types produce higher 100 seed weight, dry seed weight per plant, dry seed weight per plot, and number of pods per plot compared to ultisol soil and have a faster flowering age. However, these soil types have no significant effect on plant height, the number of productive branches, and plant root length. The combination of palm kernel ash and soil type had a significant effect on 100 seed weight, dry seed weight per plant, dry seed weight per plot, and number of pods per plot. However, this combination had no significant effect on plant height, flowering age, the number of productive branches, and root length. The largest dry seed weight per plot was observed in the K3M2 treatment combination at 78.25 g, and the smallest dry weight per sample was in the K0M1 treatment combination at 47.93 g. This resulted in a 30.32 g increase in dry seed weight per plot (63.27%). The utilization of palm kernel ash at a dosage of 375 g/polybag leads to a 34.26% increase in the dry seed weight per plant, a 30.20% increase in dry seed weight per plot, and a 42.06% increase in the number of pods per plot compared to plants without palm kernel ash application.

Abstract

This study aimed to determine the habitat approach on potato cultivation to increase diversity of insects. Habitat improvement design by agricultural system and planting system on different season. This study consisted of two experiments. The first done at planting season from March to July (dry season) and the second done at planting season from October to January (rainy season). Research designed by Split plot design with main plot are farming systems (inorganic farming and organic farming) and the subplot are the design of cropping system (sole potato; potato and cabbage; potato and mustard; potato and onion). The data was analyzed by ANOVA and Tukey test. The result showed that planting season from March to July (dry season) as well as the planting season from October to January (rainy season) showed that insect diversity index, predator population and parasitoid population were higher in organic farming compared to inorganic farming systems. The design of cropping system significantly affect insect diversity index,natural enemies population such as predator Coccinelids and parasitoid Braconid wasp and M. persicae population. In organic farming, intercropping potato with cabbage found the highest insect diversity index and the highest population of parasitoid Braconid wasp and the lowest population of M. persicae. The highest population of predator Coccinelids found at interropping potato with mustard. Combined analysis of the planting on dry season and rainy season showed that insect diversity index and population of parasitoid Baraconid wasp not significantly difference between planting on dry planting and planting on rainy season. On the other hand, population of predator Coccinellids and M. persicae significantly more higher at planting on dry season than planting on rainy season.

Abstract

The purpose of this study is to investigate the morphophysiological characteristics of teak plants (Tectona grandis) in Sarinembah Village, Karo Regency. The research method employed in this study is a survey method, focusing on identifying the morphological characteristics of teak plants in Sarinembah Village, Karo Regency, and North Sumatra Province. The study explores the morphological characteristics of teak plants, including leaf color, leaf shape, leaf tip, leaf base, leaf edge, leaf surface texture, leaf vein pattern, height, and diameter of teak trees. The results show variation in leaf color depending on the position on the tree, with leaves typically being elliptical or inverted egg-shaped, pointed at the tip and base with flat edges, rough surface texture, and reticulate leaf veins. Additionally, the height and diameter of teak trees vary, influenced by genetic factors affecting tree growth.
