Abstract

Penelitian ini bertujuan untuk mengkaji potensi penggunaan sensor optik dan ultraviolet (UV) dalam deteksi mata uang, dengan fokus pada autentikasi dan identifikasi nominal uang. Penggunaan metode Tinjauan Pustaka pada 13 artikel terindeks Scopus yang dikaji dan dipilih berdasarkan kriteria inklusi serta eksklusi yang ketat. Hasil review menunjukkan bahwa sensor optik digunakan untuk mengidentifikasi nominal mata uang dengan membaca pola cetakan mikro, sedangkan sensor UV diterapkan untuk memverifikasi keaslian uang dengan mendeteksi watermark atau serat tersembunyi yang hanya terlihat di bawah sinar ultraviolet. Kombinasi kedua teknologi ini terbukti meningkatkan akurasi dan kecepatan dalam mendeteksi uang, serta memberikan kontribusi dalam meningkatkan aksesibilitas bagi penyandang tunanetra. Penggunaan gabungan sensor optik dan UV memungkinkan alat deteksi yang dikembangkan untuk memiliki fungsi ganda, yakni identifikasi nominal dan verifikasi keaslian uang dengan tingkat keandalan yang lebih tinggi. Penelitian lanjutan perlu dilakukan untuk mengoptimalkan kombinasi kedua sensor tersebut guna meningkatkan deteksi uang yang lebih akurat dan efektif dalam berbagai kondisi pencahayaan. Selain itu, penelitian juga perlu fokus pada kemudahan penggunaan dan aksesibilitas teknologi untuk penyandang tunanetra dalam transaksi keuangan secara mandiri.

Abstract

The use of plastic as a packaging material remains the primary choice among Micro, Small, and Medium Enterprises (MSMEs) due to its practicality and affordability. However, growing environmental awareness has encouraged the adoption of sustainable packaging as a more ecologically responsible alternative. This activity aimed to assist Rena Snack in identifying and applying environmentally friendly packaging alternatives suited to the characteristics of its products. The program was implemented in three stages: preparation, implementation, and monitoring and evaluation. The results showed that sustainable packaging was relatively easy to implement, effectively maintained product quality during distribution, and remained cost-efficient. However, several challenges emerged, including mismatched packaging sizes, limited resistance of paper materials to oil and moisture, and extended processing times when using banana leaves. The sustainability evaluation indicated that the combination of paper and banana leaves held promising potential for broader application, provided there were adjustments to production efficiency and alignment with consumer preferences. This initiative is expected to encourage broader adoption of sustainable packaging practices among MSMEs to enhance competitiveness in the green economy era.

Abstract

PT Prima Parquet Indonesia is a manufacturing company engaged in wood processing, particularly in the production of Falcata Plywood. The company faces challenges in managing raw material inventory, such as procurement delays, overstock, and material shortages, which can disrupt the production process and increase operational costs. This study aims to design a raw material planning and inventory control system using the Material Requirement Planning (MRP) method to ensure the availability of raw materials in a timely, efficient, and production-oriented manner. The research stages include developing a Master Production Schedule (MPS), creating a Bill of Material (BOM), collecting lead time data, and calculating net requirements using the lot sizing technique. The results show that the implementation of the MRP method, particularly with the Lot for Lot (LFL) technique, is more optimal than the company’s conventional method because it can reduce inventory costs and prevent both shortages and excesses of raw materials. The application of the MRP system also improves operational efficiency, supports structured production planning, and ensures smoother production processes at PT Prima Parquet Indonesia. Therefore, the MRP method can serve as a strategic solution for raw material inventory control in the wood processing industry.

Abstract

Water quality is a crucial factor in determining the performance and sustainability of the biodigester system. The content of heavy metals in water has the potential to affect the biological process of biogas formation as well as have an impact on environmental health. This study aims to analyze water quality as biodigester inputs based on heavy metal content in 15 sub-districts in Kebumen Regency in order to support the development of biogas as an alternative energy source to support the SDGs program of clean and renewable energy villages. Water sampling was carried out randomly in 15 sub-districts representing mountainous, plain, coastal, and urban areas. Heavy metal concentration measurements were carried out at the UPTD Environmental Laboratory of the Kebumen Regency Environment, Marine and Fisheries Office. The parameters analyzed included levels of chromium (Cr) IV, iron (Fe), copper (Cu), and zinc (Zn). Data was analyzed using a statistical process control approach through a statistical control map to evaluate process variations, as well as process capability analysis using Pp and Ppk indices to assess the ability of water sources to meet the quality standard specification limit as a biodigester input. The results of the study show that there is a variation in heavy metal content between sub-districts. Toxic chromium concentrations with a value of ? 0.67 mg/L were identified in five sub-districts, namely Klirong, Petanahan, Buluspesantren, Karanggayam and Kebumen. Copper concentrations close to the limit of 0.02 mg/L which have the potential to inhibit enzyme activity were found in Petanahan and Kebumen Districts. Based on the analysis of process capabilities, one sub-district was categorized as very good, nine sub-districts were acceptable, and four sub-districts were categorized as poor as biodigester input water sources. These results show that the statistical process control approach is able to provide a quantitative evaluation framework for water quality consistency at the regional scale to support the development of renewable energy-based biodigesters.
