Abstract

Sabrang Village is one of the villages in Ambulu sub-district, Jember Regency, the majority of the population make a living as farmers and ranchers.  Animals that are farmed are cows. Manure waste from cattle in Sabrang Village has not been managed and utilized properly, so if it can be managed properly, it will be able to improve the welfare of the people in the village.  This is in line with the Community Service Team program on livestock waste management and treatment to reduce environmental pollution. One that supports this program is to process livestock manure waste into something useful, one of which is an alternative fuel such as biogas. Therefore, it is necessary to increase public insight into the utilization of livestock manure waste into biogas.  This can later meet people's needs for fuel that will be useful for their lives later.

Abstract

The textile industry, particularly the batik sector, significantly contributes to the Gross Domestic Product (GDP) of East Java Province. However, the batik dyeing process, which uses synthetic dyes like remazol, rapid, and naphthol, causes environmental issues due to the non-biodegradable nature of these dyes, leading to environmental pollution such as an increase in color levels in water bodies. This research investigated using activated sugarcane bagasse with KOH and HCl in batch adsorption systems as an alternative method. It compared the color efficiency removal in batik wastewater with variation biosorbent mass, contact time, and activator type. The study found that the highest percentage removal of dye substances was achieved with the KOH-activated biosorbent, reaching 69.46%, and the HCl-activated biosorbent demonstrated a 60.98% removal efficiency with a mass variation of 0.4 grams and a contact time of 30 minutes. Statistical analysis using multiple linear regression showed that independent variables (biosorbent mass, contact time, and activator) significantly affect the dependent variable (color removal efficiency) simultaneously. In the partial test, the independent variables of biosorbent mass and type of activator significantly affect color removal efficiency, but contact time does not significantly affect color removal efficiency.

Abstract

Wulan Coffee Agroindustry is among the coffee-producing centers in Maesan Sub-district, Tanah Wulan Village. This Sub-district is included in the area to apply for certification by the Geographical Indication Protection Society (GIPS) for Hyang Argopuro Arabica Coffee products. Therefore, this research aimed to formulate a strategic recommendation for developing the Wulan Coffee Agroindustry in dealing with GI certification using the SWOT method. The study included identifying internal and external factors, weighting, and strategy analysis using the SWOT method. The results showed that the total score of the IFAS matrix was 1.178 while the EFAS matrix was 0.070, indicating the IE matrix’s position was in the first quadrant of the aggressive strategy. In quadrant I, an aggressive strategy could maximize the strength possessed by Wulan Coffee Agroindustry to deal with existing threats. The aggressive strategy consisted of implementing and maintaining SOP related to sustainable coffee cultivation and production methods, increasing promotional efforts, and branding of monthly coffee products based on GI. This strategy also included certification efforts for export product development, and improvement of coffee agrotourism clusters comprising several stakeholders such as village, sub-district, and the local government of Bondowoso Regency.

Abstract

Abstract Increasing industrial and human populations potentially lead to various types of water contamination and increasing water demand. Membrane technology is a popular technology that is highly efficient in separation processes and is cost-effective for water purification. One membrane technology that is widely applied in industry is microfiltration membranes. Microfiltration membranes can operate at pressures in the range of 0.02 to 0.5 MPa, thus enabling the separation of high molecular weight compounds at low pressure. Polyvinylidene fluoride (PVDF) is a commonly used microfiltration membrane material known for its excellent thermal stability, chemical resistance, and ease of membrane formation. However, PVDF has a hydrophobic structure that has low water flux. The hydrophilicity of the PVDF membrane surface modification is an effective strategy to enhance water flux. This experiment aims to increase the hydrophilicity of the membrane using polyvinyl alcohol (PVA). In this study, surface modification of the PVDF membrane is performed using polyvinyl alcohol (PVA), a hydrophilic substance that enhances the membrane's ability to attract water. The addition of 0.1% PVA yielded the average flux value, achieving 65.7 Lm⁻²·h⁻¹. PVA increases the hydrophilic properties of the PVDF membrane and could be a modification agent for water treatment or purification. Keywords: Flux, Membran Surface Modification, PVDF, PVA Abstrak Populasi manusia dan industri yang meningkat dapat mengakibatkan berbagai jenis pencemaran air dan meningkatkan kebutuhan air. Teknologi membran menjadi teknologi populer dengan tingkat pemisahan efisiensi tinggi serta harga yang relative murah untuk pemurnian air. Salah satu teknologi membran yang diterapkan secara luas di industri adalah membran mikrofiltrasi. Membran mikrofiltrasi dapat beroperasi pada tekanan dengan rentang 0,02 sampai 0,5 MPa, sehingga memungkinkan pemisahan senyawa dengan berat molekul besar bertekanan rendah. Material membran mikrofiltrasi polyvinylidene fluoride (PVDF) merupakan material dengan stabilitas termal, ketahanan terhadap bahan kimia yang baik, serta mudahnya kemampuan pembentukan membran. Namun PVDF merupakan polimer yang memiliki struktur hidrofobik yang membuat membran rentan terhadap fluks rendah. Inovasi peningkatan hidrofilik permukaan membran pada material PVDF merupakan salah satu cara efektif meningkatkan fluks pada membran. Penelitian ini bertujuan untuk meningkatkan hidrofilisitas permukaan membrane PVDF yang berpengaruh terhadap nilai fluks. Modifikasi permukaan membran pada penelitian ini menggunakan Polyvinyl Alcohol (PVA) karena PVA bersifat hidrofilik yang dapat meningkatkan kemampuan membran menarik air. Penambahan 0,1% kadar PVA nilai fluks mencapai 65,7 Lm-2h-1. PVA meningkatkan sifat hidrofilik membrane PVDF dapat menjadi salah satu agen modifikasi untu pengolahan atau pemurnian air.

Abstract

Household-scale laundry wastewater contains phosphate, which poses significant environmental risks. This study aims to analyze the effectiveness of the adsorption process using activated carbon and activated zeolite in reducing phosphate concentrations from household laundry wastewater. The initial phosphate concentration in the wastewater was 5.19 mg/L. Adsorption was carried out using mass ratios of activated carbon and zeolite of 25:75, 50:50, and 75:25, as well as variations in zeolite activators using HCl and KOH. The research procedure included collecting laundry wastewater samples, drying and activating zeolite using 1 M HCl and 1 M KOH solutions, and mixing the adsorbents with wastewater in a batch system for 60 minutes under constant stirring. After the adsorption process, samples were filtered and analyzed for phosphate concentration using the spectrophotometric method. The results showed that the lowest phosphate concentration after adsorption was achieved with a mass ratio of activated carbon and zeolite activated by KOH at 25:75, which was 1.84 mg/L, with a phosphate removal efficiency of 64.5%. Statistical analysis using two-way ANOVA indicated that the mass ratio of activated carbon and zeolite significantly affected phosphate removal (p-value = 1.1 × 10⁻⁶), while the type of activator did not show a significant effect. This suggests that the appropriate mass ratio of activated carbon and zeolite can be an environmentally friendly and economical alternative for treating small-scale laundry wastewater.
