Abstract

Traditional land management system for agricultural activities is carried out throughout the year. It will trigger soil degradation, if it is not accompanied by adequate soil conservation practices. This research aimed to analyze the environmental friendliness of traditional land management systems based on erosion predictions and analyze, plan, and determine appropriate land use planning or conservation measures to increase their environmental friendliness.This research was conducted at three locations representing three traditional land management systems i.emamar system at Teunbaun, slash and burn system at Niukbaun and silvopasture at Merbaun, Amarasi Barat, Kupang, East Nusa Tenggara. This research was conducted in several stages, such as: secondary data collection, observation or primary data collection in the field, laboratory analysis, calculation of erosion factors, prediction of erosion according to the USLE method and recommendations for soil and water conservation measures. The results showed that the slash and burn system had the highest predictive value of erosion (A), namely 2,368.7 ton ha-1 year-1, followed by thewanaternak and mamar system 599.9 to 1,534.5 ton ha-1 year-1. The erosion value (A) can be minimized with conservation measures. Hence the erosion is less than tolerable soil loss (TSL). The recommended conservation action is construction gulud terraces. Crop management that can be done is to increase the density of plant canopy through high agroforesty, crop rotation, and mulching.

Abstract

Cucumber (Cucumis sativus L.) has a fairly good nutritional content and is in great demand by the public. Cucumber production in NTT continues to increase, but it is still low when compared to national production data. One of the efforts made is to use liquid organic fertilizers that are cheap and easy to get around us because they come from natural ingredients, namely plant residues or animal remains. Lamtoro leaf extract (Leucaena leucocephala, Ssp) is an organic fertilizer made from plants that is environmentally friendly. In addition to the fertilization factor, pruning activities are also needed to increase the weight of cucumber production. Pruning is a common cultivation action to limit excessive vegetative growth in plants so that nutrients or nutrients can be absorbed by the parts of plants that need them optimally. These nutrients can be provided by lamtoro leaf extract, then pruning is also carried out in order to reduce photosynthetic competition in order to increase cucumber production. Based on this description, it is felt that it is necessary to conduct research on the effect of giving concentration of lamptoro leaf extract and pruning on cucumber plant production. The purpose of this study was to determine the interaction of giving lamptoro leaf extract concentration and pruning on cucumber plant yields. This research was conducted from May to June 2022. This study was arranged using a randomized block design (RBD) in a factorial pattern with two factors. The first factor was the application of lamtoro leaf extract fertilizer consisting of four levels, namely: L0: control (without lamtoro leaf extract), L1: 400 cc of lamtoro leaf extract liter of water-1 plot-1, L2: 450 cc of lamtoro leaf extract liter of water-1 plot-1, L3: 500 cc of lamtoro leaf extract liter of water-1 plot-1. The second factor is pruning (P) consisting of three treatment levels, namely: P0: No pruning, P1: Pruning one leaf and one branch on segments 6–12, P2: Pruning two leaves and two branches on segments 6–12. The results obtained: administration of 500 cc of lamtoro leaf extract liter of water-1 plot-1 and pruning of two leaves and two branches on segments 6–12 of cucumber plants had a very significant effect on cucumber plant yields, concentration of 500 cc of lamtor leaf extract lamtoro liter of water-1 plot-1 and pruning two leaves and two branches on 6–12 plant nodes produced the best growth and yield of cucumber plants, the interaction between lamtor leaf extract and pruning resulted in plant length 79.33, fruit weight 284.83 g, fruit length 30 cm and fruit diameter of 4.48 cm. Recommendation: for cucumber cultivation, it is better to use POC of lamtor leaf extract 500 cc of lamtoro leaf extract liter of water-1 plot-1 and pruning of two leaves and two branches on internodes 6-12 plants. There needs to be further research on the use of POC concentrations of lamtoro leaf extract with higher concentrations to reduce the use of inorganic fertilizers.

Abstract

Long bean (Vigna sinensis L.) is a vegetable commodity containing 2.70 mg protein, 2.30 mg fat, 44 cal calories, 7.80 mg carbohydrates, 347 mg phosphorus, 47 mg calcium, 335 SI vitamin A, 0.39 mg B vitamins. , 21 mg of vitamin C and 88.50 mg of water. Production of Vigna sinensis L in NTT in 2019-2021 continues to increase but the phenomenon of rising long bean prices indicates that long bean production needs to be increased. One of the efforts made is to increase the availability of soil nutrients through fertilization. The aim of the study was to determine the interaction effect of NPK dosage and young coconut water concentration on the yield of long bean plants. The research was conducted in June-July 2022 using the Randomized Block Design (RBD) experimental method with 2 factors and 3 treatment levels, namely: Factor I = NPK Fertilizer (A) and Factor II = Concentration of young coconut water (K). The results obtained: The treatment of NPK fertilizer and young coconut water had a very significant effect on the growth components of long bean plants as indicated by differences in plant height, number of leaves, number of pods and pod weight. The interaction between the application of NPK fertilizer (NPK 250 kg/ha) and the concentration of young coconut water (90% /1L) gave the best results giving the best results on the average plant height, number of leaves, number of pods and pod weight of long bean plants.

Abstract

Traditional land use is a method of land use that has been carried out for generations by the community. Land management activities carried out from generation to generation, with the same pattern from year to year, such as land use which is often called Tebas Bakar and Mamar. Both land uses with different management methods can indicate changes in soil conditions as a medium for plant growth in their physical properties. The purpose of this study was to determine soil permeability in traditional land cultivation activities in Niukbaun Village, West Amarasi, NTT. Field and laboratory research was carried out in August-October 2024. The research location was in Niukbaun Village, West Amarasi District, with the traditional Tebas Bakar and Mamar management systems. Research Methods Data collection includes primary data, secondary data, Permeability observations were carried out in the field using a permeameter. The results obtained: Soil permeability on mamar land is better than slash and burn land. Each type of traditional land use differs according to its management method. So that texture, organic material and land use processing have an influence on the size of the soil permeability.

Abstract

This community service initiative aims to empower young generations and housewives in Manulai II Village, Alak District, Kupang City, through the development of homemade shrimp paste sambal production as a creative economic opportunity. In the context of contemporary economic dynamics characterized by digitalization and changing consumption patterns, the micro-culinary sector offers significant potential for empowerment, although young generations and housewives often face limitations in access to technical knowledge, capital, and marketing strategies. Based on data from the Central Statistics Agency of East Nusa Tenggara Province (2023), the fisheries sector contributes 12% to the regional GRDP, with abundant rebon fish production that has not yet been fully utilized innovatively. The main objectives of the activity are to enhance creative skills in shrimp paste sambal production, form independent micro-business groups, and contribute to inclusive local economic growth. The applied methods include a participatory approach with stages of preparation, training, mentoring, and evaluation over six months, involving 30 participants and collaboration with local stakeholders. The results indicate a 75% increase in technical knowledge, the formation of 3-5 independent business groups with an initial sales volume of 200 kg per month, and an average 20-30% increase in household income. The discussion highlights the effectiveness of Freire's (1970) model in critical education and the relevance of Schumpeter's (1934) innovation theory in opening new market opportunities. The conclusion emphasizes that this initiative strengthens community economic resilience and supports sustainable development agendas, with recommendations for long-term monitoring to ensure business sustainability.
