Abstract

Indonesia is an agricultural country and one of the world's rice-producing countries. However, the increase in population has pushed for the conversion of agricultural land to non-agricultural purposes. Solok is a district with the largest paddy field area in West Sumatra. Yet, the increase in population has resulted in a decrease in paddy fields every year. This study aimed to determine the model for changing the area of paddy fields for the 2000-2020 period and determine the direction of sustainable agricultural policies. In defining the paddy field change model, this research uses the input data from the interpretation of 2000 Landsat 5 imagery, 2010 Landsat 7 imagery, and 2020 Landsat Oli 8 imagery. The data were analyzed using a geographic information system (GIS). This research employed the Powersim Software with a system dynamics approach in projecting rice production and demand. This research used Interpretative Structural Modeling (ISM) analysis to determine the direction of sustainable food policy. The results showed that there had been a conversion of 13,801.6 hectares of paddy agricultural land into a built-up area in the 2000-2020 period in Solok District. In 2020, Solok District supplied 2,838 thousand tons of rice, while the demand for rice was 446.3 thousand tons. In the direction of the sustainable agriculture policy, there are three key sub-elements; tightening land use permits, establishing and implementing spatial planning regulations, and consistency in enforcing spatial planning violation laws.

Abstract

Apart from ex-mining land which requires management and rehabilitation using soil microbial communities, reclamation activities require time and technology with high costs and results that are not necessarily effective and efficient. One effective way is to provide organic fertilizer which contains lots of microbes and is able to neutralize soil acidity. This type of research is experimental research with a research design using a Completely Randomized Design (CRD) 4 x 6. The population of this research is all Ruji Nut Plants (Pueraria Javanica) that grow in the PT Mine Wire House area. The main natural coal sampled in this research were 24 Ruji Nut Plants (Pueraria Javanica). The results of this research were that administering NPK solution and Micro Nano Bubbles (MNBs) was proven to help accelerate stem growth, number of leaves, number of leaf branches, root length and increase the biomass of Ruji Nut (Pueraria Javanica) plants in planting media with minimal topsoil. The dosage of Organic NPK Solution and Micro Nano Bubbles (MNBs) for optimal growth of Pueraria javanica plants was in treatment 4 (90 ml), where in treatment 4 the average stem growth, number of leaves, number of leaf branches, root length and plant biomass reached optimal point. So the use of Organic NPK solution using Micro Nano-Bubbles (MNBs) is more effective and environmentally friendly because it is formed from organic materials.

Abstract

Reverse Osmosis (RO) drinking water management can be the best solution to overcome the clean water crisis in Pulau Pinang. RO is a process that allows water to pass through a semi-permeable membrane and separates most of the dissolved salts, organic matter, bacteria, and other substances from the water to produce clean water. The use of the RO method in drinking water management is one of the best alternatives to overcome the clean water crisis, especially in the Pinang Island area with surface water sources that are not dominated by freshwater can ensure the availability of sustainable clean water. However, RO-based drinking water management is water demineralization, so further management is needed such as remineralization to meet mineral standards in drinking water.
