Application of Remote Sensing and GIS for Land Use Mapping and Impact on Food Supply in South Denpasar. The increasing demand for land, driven by population growth, societal development, and economic progress, leads to land use conversion. The conversion of agricultural land to non-agricultural purposes has implications for food availability. This research aims to assess land use changes over an 11-year period (2012-2023), determine the presence of subak (traditional Balinese irrigation system) in 2041 based on the Regional Spatial Plan (RTRW) map, and project the analysis of food availability in 2030 and 2040 due to land use changes. The methods employed include satellite image interpretation, digital mapping, map overlay, and food availability analysis. The research findings indicate land use changes from 2012 to 2018 resulted in a conversion of 140,66 hectares (23,44 ha/year), and from 2018 to 2023, a conversion of 18,8 hectares (3,76 ha/year), with a total conversion of 159,46 hectares (14,50 ha/year) from 2012 to 2023. Based on the RTRW spatial plan map for 2021-2041, South Denpasar is projected to potentially 4 subak located outside agricultural zones. Land use changes in South Denpasar have implications for the rice food balance, with a projected deficit of (-19.973) tons in 2030 and (-20.563) tons in 2040. Reevaluation of land use allocation policies is necessary due to their impact on food availability, environment, social, and culture.

Testing the Effect of Trichoderma harzianum Pellet and Capsule Inoculant on Resin Content in Agarwood Wood on Different Lands. Resin is a secondary metabolite compound produced by agarwood plants due to injury or infection by microbes. The formation of gaharu resin is influenced by the genetics of the resin-producing tree, the type of inducing microbe, the environment and the length of the resin formation process in gaharu. Previous research showed that inoculant pellets and Trichoderma harzianum mushroom capsules could increase the resin content in agarwood in the Dauhpuri Marga Village experimental garden. This research aims to prove the effect of inoculant in Trichoderma harzianum mushroom pellet and capsule packaging on the resin content in agarwood in several different fields. This research is an experimental research with a factorial pattern RCB design. The first factor is the type of inoculant packaging with 3 levels, namely: F0 (without inoculant), Fp (pellet inoculant), Fk (capsule inoculant). The second factor is land type consisting of 3 levels: Kl (Klungkung), Mg (Marga), Sl (East Selemadeg). The parameters observed were: color of agarwood, aroma of agarwood, resin content in agarwood. Quantitative data from observations/measurements are analyzed statistically using variance analysis, if significant occurs, it is continued with the Duncan Test. The research results showed that the type of inoculant packaging had a significant effect on the resin content in agarwood, but the type of land had no significant effect on the resin content in agarwood. This proves that Trichoderma harzianum fungus pellet inoculant can increase the resin content in agarwood on various different fields.

Application of Household Waste Liquid Organic Fertilizer on the Growth and Yield of Pakcoy Plants. Providing nutrients to cultivated plants is very important to support plant growth and development. The aim of the research was to determine the effect of household waste liquid organic fertilizer on the growth and yield of pak choy plants and which liquid organic fertilizer gave the best results. The research was carried out in a greenhouse using a completely randomized, non-factorial design. The research used polybags filled with 10 kg of soil as a medium and planted with pak choy vegetable plants. There are three treatments used, namely liquid organic fertilizer derived from rice washing water (POCB), onion skin washing water (POCBM), and fermented fruit residues (ecoenzymes) (POCEE). There were three treatments, namely: no treatment, giving 100 ml/1 liter of water, and giving 200 ml/1 liter of water. The number of treatments was 9 and repeated 4 times, so there were 36 treatments, and 2 plants were planted in each treatment, a total of 72 plants. Maintenance includes watering, cleaning plant media, and spraying using vegetable herbicides. The parameters observed were plant height, number of leaves, and fresh weight. Observations were made two weeks after planting, and then once a week until 45 days old (harvest). Based on the research results, the treatment that provides the best growth is ecoenzyme. The highest plant height was with the ecoenzyme treatment of 200 ml/1 liter of water (POEE2), followed by POBM2, POB2, namely 18.16 cm; 16.98 cm and 16.84 cm, the number of leaves is 9.6 pieces; 9.4 strands and 9.6 strands, and fresh weight 20 g; 19.5 g and 18.9 g. The results of the research are a recommendation that household waste is useful for making liquid organic fertilizer, as shown by the growth and fresh weight yield of pak choy plants.
