(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Water is one of the main needs of living things. Everyday human life needs water, starting from drinking water, water recreation, aquaculture, animal husbandry and agriculture. About ¾ of the human body is made up of water. Water is very important, so humans must maintain the availability of water. Water availability needs to be balanced with the maintenance of water quality, so that it can be seen that the water is in good condition or polluted. Clean water needs attention according to SDGs number 6 concerning the availability of clean water and sanitation. The quality of water in water bodies such as rivers, lakes, swamps, reservoirs and others needs to be monitored so that water can be used properly according to its purpose. This study aims to examine the method of calculating the water quality index which is commonly used in determining water status so that the characteristics of the water quality method can be identified and the advantages and disadvantages of this method. The method used is literature study from related journals. The water quality index (IKA) method used in Indonesia includes the IP, Storet and NSF WQI methods. The results of the study will describe the advantages and disadvantages as well as the characteristics of the appropriate method used in accordance with the research needs which are expected to facilitate the selection of water quality monitoring methods.

The overuse of chemical fertilizers can have detrimental effects on soil quality. It is important for farmers to find sustainable alternatives. One possible solution being explored is the use of liquid maggot derived from organic sources. This study aimed to determine the most suitable composition that fulfills plant needs and follows established guidelines. The research approach employed a qualitative descriptive method to assess the impacts of three treatments using different types of organic matter: fruit waste, restaurant waste, and palm oil cake. Phosphorus and potassium concentrations were determined through MP-AES analysis while nitrogen content was measured using the Kjeldahl method. The findings revealed that only the treatments involving fruit waste and restaurant waste met the recommended potassium levels. However, these treatments fell short of meeting requirements for other essential nutrients. As a result, additional research is needed to assess nutrient concentrations in different organic substances.

Phylogenetic study of Phytophthora palmivora species utilizing nucleotide sequences of rDNA ITS and genes was conducted to evaluate the cladistics and evolution of kinship among P. palmivora species in order to support genetic diversity and linkages and also compare with sequences of mitochondrial COX1. The analysis included 61 nucleotide sequences of P. palmivora rDNA ITS and one outgroup as well as 56 nucleotides sequences of COX1 retrieved from the NCBI GeneBank, which were aligned and trimmed using MEGA 11 software. The Kimura-2 parameter model and Maximum-Likelihood approach were used to create a monophyletic tree with four major clades. The percentage of GC content in DNA sequences was less than 50%, influencing genetic diversity and adaptation throughout evolutionary time periods. Temperature, humidity, rainfall, soil moisture, and seasonal fluctuations all work together to generate optimal climatic and weather conditions for the establishment and development of Phytophthora palmivora in tropical climates.

Background: Plastic debris smaller than 5 mm is categorized as microplastic, a pollutant with persistent characteristics that often contains toxic or carcinogenic compounds. These particles can infiltrate soil systems, migrate into the food chain, and ultimately threaten both environmental integrity and human health. This research focuses on identifying the types and quantifying the abundance of microplastics in soils collected from three final disposal sites in Lampung Province, Indonesia. Methodology: Sampling at three landfill points was carried out purposive sampling method, with microplastics sample analyzed through visual inspection by microscopy and polymer composition confirmed using Fourier Transform Infrared (FTIR) Spectroscopy Method. Findings: Landfill sites B1 and C1 exhibited the highest abundance of microplastics, reaching 195 particles per kilogram of soil. The particles displayed morphological diversity, including fragments, fibers, and films, with fragments representing the predominant category. The color distribution was largely transparent, black, and brown, while the detected particle sizes ranged from 2.12 to 110.25 μm. Polymer analysis revealed the presence of polyethylene (PE), polyamide, and polystyrene, alongside particles suspected to be polyethylene terephthalate (PET). These findings indicate that physical and chemical degradation processes accelerate the breakdown of plastics into smaller fragments, thereby contributing to elevated microplastic levels in landfill soils. Contribution: The outcomes of this research, derived from visual microscopy and FTIR Spectroscopy-based identification of microplastics in Lampung landfill soils, The findings offer essential data for the development of monitoring frameworks and risk assessment strategies related to soil and environmental risks in the region

Global environmental monitoring shows that conditions in developing countries are increasingly worrisome. Water pollution is a problem that often occurs. There are 82% of 550 popular rivers in Indonesia that are damaged by pollution. Rivers are synonymous with irrigation sources, household water supplies, industrial needs, and others, so they cause serious hygienic and ecological problems. However, water's current existence is based on environmental disasters, land use, geopolitical conflicts, pollutants, and population growth. This paper aims to determine the efforts to control pollution in dealing with river pollution problems legally and provide recommendations for a River Management Strategy based on experts' opinions in the field of water resources as an alternative to pollution control. The method used is descriptive qualitative to describe efforts to control river pollution and river management strategies. This research is focused on the problems of the Sikendil River and the Selilin River in Klepu Village, Pringapus District, Semarang Regency. The results showed that controlling water pollution by stakeholders requires good coordination and facilitation from related agencies, starting from improving the social, technological, regulatory, and institutional foundation and the ecological foundation of the industry and surrounding communities so that river pollution problems can be resolved. Environmental policies in the form of law enforcement and stakeholder support are needed to improve the environment and oversee the course of environmental problems. The most dominant and most important aspect is social institutions with a value of 0.427, and the most dominant alternative is community participation with a value of 0.546, so that the aspect of social institutions with alternative community participation can be the most prioritized strategy to be applied in cases of legal river pollution.
