Abstract

Cayenne pepper is a commodity that is quite high in demand in Indonesia. The problem in chili nurseries is to ensure that the plants grow vigor after the transplanting process is carried out. For this reason, it is necessary to provide vitamins to accelerate the adaptation process so that chili plants can grow optimally. To overcome this problem, in this study the application of vitamin B1 (thiamine) was carried out at the beginning of transplanting cayenne pepper seedlings from the nursery. The purpose of this study was to determine the effect of the application of vitamin B1 on cayenne pepper seeds and the best concentration of vitamin B1. This research will be carried out for three months, from early June to the end of August 2023. The research will be conducted in Kelurhan Sidomulyo, Kecamatan Medan Tuntungan, Kota Medan. The research design was a completely randomized design with 1 factor and 3 replications. The treatment factor was the concentration of vitamin B1 with 4 levels. V0: control; V1: 0.5 ml/l vitamin B1; V2: 1 ml/l vitamin B1; and V3: 1.5 ml/l vitamin B1. The results showed that the administration of vitamin B1 (thiamine) during transplanting had an effect on the growth of cayenne pepper seedlings.

Abstract

AbstractMelon is a fruit plant that has a high nutritional value. A limited agricultural land encourages the application of alternatives planting method and utilizes local materials around the community as potential planting media towards resulting a high-yielding variety. One of the cultivation techniques is the use of the hydroponics system. The objective of this study is to determine the most suitable planting medium for melon varieties to be planted hydroponically. This research was conducted in the greenhouse at the sub-district of Medan Tuntungan in the city of Medan during May to August 2017. This research used Randomize Complete Block Design Factorial with 3 replications. The use of planting media consisted of charcoal husk, cocopeat, sawdust and sand; whereby the treatment of varieties consisted of Aramis F1, Amanta F1 and Red Aroma. The results showed that the best medium for hydroponics melon is charcoal husk highlighting significant result onto the plant height, number of leaves and fruit weight of crops, from the use of charcoal husk media.Keywords: hydroponic, soilless culture, melon, medium and variety

Abstract

Alang-alang (Imperata cylindrica) and Saliara (Lantana camara) are dominant weeds in several crop cultivation areas, so that when control is carried out, waste from both weeds will be produced in large quantities. Management of waste from both weeds can be done by utilizing it as a more environmentally friendly bioherbicide. Bioherbicide application is carried out pre-growth so that control is carried out faster and attacks newly germinated weed seeds, so that weeds do not appear on the surface and weed control activities will be more efficient. Alang-alang is the most dangerous weed and is highly avoided because it contains allelochemical compounds that can inhibit the growth of the main plant, this compound is found in all parts of the weed but is found most in the roots. Saliara also has a high content of allelochemical compounds which causes a distinctive aroma from its leaves. The allelochemical content of both weeds can be used as active ingredients in bioherbicides and is effective in controlling other weed species. Several studies have reported that bioherbicide extracts from both weeds are effective in inhibiting weed growth so that they can be used as an alternative to herbicides. However, bioherbicide application must be carried out with the right technique and concentration so as not to interfere with and inhibit the growth of the main plant.

Abstract

The main problem faced by the Sumber Rejeki Farmers Group in Percut Village, Percut Sei Tuan District, is the low productivity of rice due to saline land and pest infestations. The high soil acidity and low fertility are the main factors hindering rice growth. To address this issue, the community service team from Universitas Sumatera Utara (USU), in collaboration with student activity units, Himadita Nursery, implemented a program utilizing Liquid Organic Fertilizer (LOF) Jakaba (Eternal Lucky Mushroom) and planting refugia plants. LOF Jakaba, derived from mushroom cultivation, helps reduce soil acidity and increases essential nutrients, thereby improving soil structure. Meanwhile, refugia plants serve as habitats for natural pest predators, enabling ecological pest control and reducing reliance on chemical pesticides. The methods used in this program included socialization, training, and assistance for farmers in producing and applying LOF Jakaba, as well as planting refugia plants. The results of this initiative showed improved soil fertility, reduced pest infestations, and increased rice productivity. The conclusion of this activity is that this sustainable agricultural approach has the potential to serve as a model for other areas facing similar challenges and can enhance the well-being of farmers in Percut Village.
