Abstract

This research aimed to analyze potential supply and removal of biomass and soil nutrients induced by different vegetation on peatlands. The research was carried out in peats dome of the catchment area of the Sibumbung River and the Burnai River in Pedamaran Sub-Districts, OKI South Sumatra. The research method used field survey of case studies of four natural phenomena (swamp grass, bush swamp, pulai peatlands, and peat forest). The research resulted that the highest production and harvest of biomass came from peat forest, pulai peatland, bush swamp and swamp grass. The highest biomass supply to the soils were given by the peat forest, pulai peatland, bush swamp and swamp grass (around 12,545; 11,593; 7,491 and 5,313 kg/ha/year respectively). The more varied the vegetation type, the higher the supply of soil nutrients. Swamp grass and bush swamp have low vegetation diversity and are mostly dominated by alang-alang. Swamp grass and bush swamp showed the same pattern and the order of nutrient supply in the highest sequence is K, Ca, N, Mg, Ca, and P. The supply order of soil nutrients (peat forest and pulai peatland) showed a similar pattern, namely from the highest content of Ca, N, K, Mg and P. Pulai vegetation can be recommended for a paludiculture system because it resembles almost the peat forest in producing biomass and soil nutrient supply to the soils and is originally native plant from peatland.

Abstract

ABSTRACT The Noman River, the main river that crosses Muaraenim Regency, South Sumatra Province, has been polluted by the liquid waste from the palm oil industry. This study aimed to create a filter device for treating the polluted water waste. This was achieved by designing a pump pressure setting on the filter device with various filter media arrangements. The method used was descriptive, presenting data in graphs and tables. The research and tool design to create a filter device for treating the polluted water waste process involved several stages: tool planning, manufacture and assembly, testing, observation, calculation, and laboratory analysis. The observed parameters included pump pressure, regulated using a pressure gauge to determine water quality before and after filtering. The parameters observed were turbidity, color, pH, suspended solids (TSS), BOD, COD, oil, and grease. The study results indicate that biosand filtration, using different pressures, can treat river water contaminated with waste from the palm oil industry and produce clean water. The initial color of the water before filtering was measured at 230 TCU. After filtering, the color value decreased at each pressure level. Pressure I had a color value of 164 TCU, higher than the 153 TCU obtained at pressure II. The BOD analysis showed a decrease from 2.43 mg/L to 1.86 mg/L at pressure I before filtering. After filtering, the initial total suspended solids (TSS) level was 39.7 mg/L, which decreased to 26.79 mg/L at pressure I and 26.40 mg/L at pressure II. The oil and fat content analysis before filtering showed a concentration of 700 µg/L, which decreased to 501 µg/L at pressure I and 516 µg/L at pressure II after filtering.

Abstract

Community service activities in Putak Village aim to educate and empower farmers and housewives in utilizing plastic bottle waste as a medium for planting hydroboks technology for vegetable crops through a simple hydroponic system (NFT). This program is carried out for five months through the stages of field surveys, counseling, technical training, mentoring, and evaluation. The results of the activity show the effectiveness of the use of plastic waste as an environmentally friendly and sustainable planting medium, helping to reduce the pile of plastic waste while providing urban farming solutions in narrow yards. This training successfully improved the community's knowledge and technical skills about hydrobacca systems, which is evident from the enthusiasm of the participants and their success in growing vegetables independently. In addition, this program has a positive impact on the economy by reducing spending on purchasing vegetables and supporting the consumption of pesticide-free fresh food. The environmental impact is also seen through increasing public awareness in managing plastic waste based on the 3R (Reduce, Reuse, Recycle) principle. The success of this program can be increased through continuous education, such as seminars, plastic waste management innovation competitions, and the creation of educational materials in the form of videos and posters to reach more bans.
