Abstract

ABSTRACT: The quality of groundwater is significantly influenced by the mineral composition of the surrounding rocks and soil in the aquifer. High concentrations of minerals, particularly iron (Fe) and manganese (Mn), can cause discoloration typically a yellow-brown hue and an unpleasant taste in the water. This study aims to evaluate the effect of different filter media arrangements in a filtration column on the reduction of Fe, Mn, and turbidity levels in well water. The natural filter media used include sand, gravel, palm fiber, and activated carbon, arranged within a filtration column model. Water samples were taken from dug wells in Sowi 2 Village and a drilled well in Susweni, Manokwari Regency. Initial characterization of the water samples included assessments of odor, color, turbidity, and Fe and Mn concentrations. Results indicate that during the rainy season, well water from Sowi 2 meets clean water quality standards based on pH, turbidity, and Fe and Mn content. However, the drilled well in Susweni exceeds acceptable limits in terms of color and pH. Filtration using the designed column and selected natural media effectively reduced Fe, Mn, and turbidity. Turbidity reduction reached 100% in both column A and B. Fe concentration was reduced by 78.53% in column A and 73.55% in column B. Mn concentration was reduced by 76% in column A and 65.45% in column B.

Abstract

ABSTRACT: Sago is a staple food especially for Papuans. To process sago, the pith crushing and extraction process is very time-consuming and labor-intensive. The purpose of this research is to develop a threaded stirrer type sago starch extraction machine equipped with a grater unit. This research consists of three stages, namely (1) machine development, (2) machine testing and (3) economic feasibility analysis. The research method used was an experimental method using a completely randomized design consisting of three treatments of the type of grater cylinder, namely (1) 4 mm iron axle 20 mm high (P1), circular saw cutting edge (P2) and chain saw serrations (P3). The performance of each treatment was evaluated by measuring variables (1) processing capacity, (2) starch yield, (3) starch production, (4) loss of starch left in the pulp and (5) gasoline fuel consumption. Based on the results of the research, it shows that the threaded stirrer type sago starch extraction machine equipped with a grating unit from the development works well in field conditions. The results of the performance test in field conditions showed that the treatment of the type of grater serrations gave no significant effect on processing capacity, starch yield, starch production, starch loss in dregs and gasoline fuel consumption. The performance of the machine under field conditions (operational) was (1) processing capacity ranged from 255.63 kg/hour - 296.61 kg/hour. (2) starch yield 23.41%. - 30.41%, (3) starch production of 59.94 kg/hour - 90.57 kg/hour, (4) starch loss in pulp of 2.20% - 2.94% and (5) gasoline fuel consumption of 1.30 l/hour - 1.42 l/hour. Economically, this machine is categorized as feasible with a BC ratio value of 2.11. The production break-even point is 3,453 kg and the price break-even point is Rp. 5,487.

Abstract

ABSTRACT: The waters of Bintuni Bay have potential mangrove crab (Scylla sp.) resources. Mud crabs are aquatic biota that have high economic value. Information about the biological aspects of mangrove crabs in the waters of Bintuni Bay is still very minimal. This research aims to examine the size structure, growth patterns, condition factors and gon-ad maturity level (TKG) of mud crabs in the waters of Bintuni Bay. The research was carried out from May to July 2023. The research results showed that the average carapace width and weight of male mud crabs were 13.6 cm and 553.2 grams. Meanwhile, the average size of the shell width and weight of female mud crabs is 12.5 cm and 284.1 grams. The average size of mangrove crabs caught is included in the catchable category (KKP Ministerial Regulation No. 16 of 2022). The growth pattern of male mud crabs is isometric (b = 3.15), while the growth pattern of female mud crabs is negative allometric (b = 2.12). The condition factor values for male and female mud crabs are 1.01 and 1.03. The results of TKG observations showed that 78.4% of female crabs were in TKG I and II, meaning that 50% of the shrimp caught had not yet reached TGK III and IV at the time of the research.

Abstract

ABSTRACT: Marine tourism is one of the region's leading sectors, significantly contributing to Regional Own-Source Revenue (PAD - Pendapatan Asli Daerah). However, tourist areas also generate waste from tourists or visitors. This study aims to identify and analyze the waste generation and composition in the Pasir Putih Beach tourist area and assess the potential for waste reduction. The research was conducted over four months (March-June 2024), with the study site located at Pasir Putih Beach. Waste generation measurements were categorized by source type: point sources and line sources. Point sources include restaurants and food stalls within the Pasir Putih Beach area, while line sources refer to marine debris along the shoreline. Waste generation from point sources was measured using the standard method outlined in SNI 19-2964-1994, which details the sampling and measurement of urban waste generation and composition. Based on the study's findings, 15 different types of marine debris were identified at Pasir Putih Beach. The most abundant components of marine debris were coconut shells (27.59%), wood (18.32%), and recycled plastic (14.61%). Organic waste generated by restaurants or cafés at Pasir Putih Beach amounted to 8 kg per unit per day, with a waste density of 0.007125 kg/m³ for cafés, while food stalls had a waste density of 0.00675 kg/m³. The average waste produced by food stalls at Pasir Putih Beach was 8 kg per unit per day, with a waste density of 0.00675 kg/m³. Waste from tourist activities, including cafés, restaurants, and food stalls, was primarily composed of kitchen waste and food leftovers, along with garden waste, such as leaves, accounting for 13.48% of the total. This waste can be processed through biological methods, such as composting or biodigesters.

Abstract

ABSTRACT: This study aims to analyze the effect of suspended particles (TSS) from various hydrological variables on the water quality of the Maruni River in Manokwari Regency. The method used in this research is quantitative descriptive method. Hydrological variable data includes calculation of erosion rate, Sediment Delivery Ratio (SDR), estimated sediment size and surface water runoff discharge. Water quality is measured based on the physical parameters of particle content/suspended density and turbidity. The sampling method refers to SNI and water sample quality testing was carried out at the University of Pa-pua PPLH Environmental Laboratory. The results showed that the erosion rate value in Maruni watershed was 101.001 (tons/ha/yr) with the category of moderate erosion hazard level. Sediment Delivery Ratio (SDR) of Maruni watershed is 0,15 or 15%. The total value of sediment potential generated is 41757,98 tons/year. The surface water runoff discharge that occurs in the Maruni watershed is 48,11 m3 /second. TSS and turbidity concentrations in hot conditions still meet the National Water Quality Standards, while in rainy conditions at mid to downstream points the TSS concentration ranges from 89 mg/L- 228 mg/L and Turbidity ranges from 76.1 NTU- 237.5 NTU has exceeded the National Water Quality Standards according to Appendix VI of Government Regulation No. 22 of 2021 class B for TSS and Minister of Health Regulation (PERMENKES) No. 32 of 2017 for turbidity. Based on the identification results, recommendations for land and water conservation efforts can be made to reduce the risks that occur and maintain water quality.

Abstract

ABSTRACT:The coastal ecosystem of Samai Island is a complex interaction between various organisms, including gastropods, and their environment. Gastropods are members of the mollusk phylum, which are invertebrates. This study aims to analyze the correlation between the structure of the gastropod community and physicochemical parameters. The research was conducted on the coast of Samai Island, Fakfak Regency, West Papua Province. Using the transect line method at four sampling stations. The results, showed that the highest gastropod density was found at Station IV (80.2 ind/m2), while the lowest was recorded at Station I (21.8 ind/m2). The gastropod diversity index ranged from 2.36 to 3.14, indicating a medium category at Stations II, III, and IV, and a high category at Station I. The evenness index was high at all stations, with values ranging from 0.61 to 0.87, and there was no dominant species at any station. The physico-chemical parameters of the water at the research location include water temperature ranging from 29.5°C to 30.4°C, salinity between 33.19‰ and 33.94‰, dissolved oxygen (DO) between 5.35 mg/L and 5.74 mg/L, and water pH ranging from 8.41 to 8.65. These parameters influence the structure of the gastropod community along the coast of Samai Island, Fakfak.

Abstract

ABSTRACT: This research aims to study the cultivation of coffee plants, specifically Robusta coffee (Coffea canephora), grown by farmers in Kampung Air Mandidi and Kampung Samabusa. Coffee cultivation began in 1998, using local seedlings obtained from previous farmers. As a refreshing beverage, coffee is important in daily life and local culture. Although coffee cultivation is not the main occupation for farmers, it shows potential for further development. This study also observed that farmers implement mixed planting systems or agroforestry, where coffee plants are grown alongside other crops such as bananas, durians, and corn. This agroforestry approach not only diversifies agricultural yields but also reduces the risk of pest attacks and enhances the sustainability of the agricultural ecosystem. The research findings indicate that despite challenges in the socialization and marketing of coffee products in the area, the cultivation system applied by the farmers contributes to their overall success and well-being. This research emphasizes the importance of promoting sustainable cultivation practices and supporting farmers facing market challenges to increase local coffee production. Additionally, it highlights the significance of coffee not only as an agricultural product as well as a source of refreshment in the community.
