Abstract

The problem faced is that the white chromium coating has a low selling value or aesthetic value than the black chromium layer which is more in demand, especially by the younger generation who prioritizes aesthetics. The purpose of the corrosion test was to determine the corrosion resistance ability of the black chromium coating resulting from the electroplating process on the relationship between the solution temperature and the immersion time of copper in a corrosive solution. Corrosion test methods include literature studies, field observations, weighing specimens, immersing specimens in corrosive solutions, weighing specimens, calculating corrosion rates, and data analyzing. Corrosion test results show that the higher the temperature of the solution and the longer the immersion time, the smaller the corrosion rate for the lowest conditions at 30oC and a duration of 5 minutes with a corrosion rate of 0.2004 mm/year and the highest conditions at a temperature of 50oC and a duration of 9 minutes at a rate of corrosion of 0.0108 mm/year.

Abstract

Micro, Small, and Medium Enterprises (MSMEs), especially in the snack industry sector, such as cassava crackers, play an important role in supporting the Indonesian economy through job creation and contribution to Gross Domestic Product (GDP). However, MSMEs often face challenges in maintaining and expanding their market share amid increasingly fierce competition. This study aims to analyse the role of social capital in strengthening market segmentation strategies at Sadariyah Cassava Crackers Business in Blitar Regency. The method used is descriptive qualitative, with data collection techniques through in-depth interviews, direct observation, and documentation. The informants in this study were five people, consisting of business owners, employees, regular customers, and local community leaders. The results show that social capital, which includes strong social networks, trust between businesses and consumers, and the application of local social norms such as gotong royong, contributes significantly to expanding the market and maintaining customer loyalty. The market segmentation strategy applied based on demographic, psychographic, and consumer behaviour factors proved effective in reaching various customer groups. These findings imply that the synergy between social capital and the right market segmentation strategy can improve the competitiveness of MSMEs in a competitive market and promote sustainable business growth.

Abstract

Thermal Tensioning is one of the methods use to minimise the occurrence of residual stress and unwanted distorsion during welding. One of the thermal tensioning methods is Static Thermal Tensioning (STT), which involves countering thermal stress during welding. The STT method requires an active cooling behind the welding line. Several properties are required for the coolant material, such as thermal conductivity, heat resistance, and good flexibility. To achieve the desired properties, a mixture of different materials was used, commonly called a composite. The purpose of this study is to know the effect of filler metal composition and type on the heat resistance of silica rubber matric composites. This study used 2 independent variables: the filler composition in composites with variations of K1 (60%) and K2 (70%), and the type of filler metal, aluminium and copper powder with variation J1 (100%-0%), J2 (75%-25%), J3 (50%-50%), J4 (25%-75%), and J5 (0-100%). The testing process used Thermogravimetry Analysis (TGA) method with replication 2 times. The results of this study showed the specimens with K1;J1 composition,containing 60% pure aluminium filler metal, showed the best heat resistance with a final weight of 88,25%. While specimens with K2;J5 composition, containing 70% pure copper filler metal, showed the worst heat resistance with a final weight of 74,25%.

Abstract

Kegiatan Pengabdian kepada Masyarakat (PkM) yang dilaksanakan pada Usaha Mikro Kecil (UMK) Bathok Koi di Kota Blitar dilatarbelakangi oleh potensi besar pemanfaatan limbah tempurung kelapa yang selama ini belum dioptimalkan secara maksimal. Tempurung kelapa yang melimpah umumnya hanya dimanfaatkan sebagai arang bakar tradisional dengan nilai ekonomi rendah, sehingga diperlukan inovasi pengolahan untuk meningkatkan nilai tambahnya. Permasalahan utama yang dihadapi mitra mencakup keterbatasan teknologi pengolahan, rendahnya pengetahuan tentang manajemen produksi, serta belum adanya struktur organisasi usaha yang sistematis dan kemitraan bahan baku yang berkelanjutan. Menjawab permasalahan tersebut, program PkM ini dilaksanakan dengan pendekatan partisipatif melalui koordinasi, diskusi, pelatihan, pendampingan, serta pengadaan teknologi tepat guna. Metode pelaksanaan terdiri atas beberapa tahapan, yaitu pengadaan dan instalasi mesin hammer mill, mixer, dan pressing otomatis, pelatihan teknis pengoperasian dan perawatan mesin, pembentukan struktur organisasi usaha, serta fasilitasi kemitraan bahan baku dengan pihak produsen minyak kelapa murni (VCO). Hasil pelaksanaan program menunjukkan bahwa mitra berhasil meningkatkan kapasitas produksi briket dengan kualitas yang memenuhi standar ekspor, baik dari aspek kepadatan, homogenitas bahan, maupun kualitas nyala. Selain itu, mitra memperoleh keterampilan baru dalam manajemen produksi, pengendalian mutu, dan tata kelola organisasi usaha yang lebih terstruktur. Keberhasilan menjalin kemitraan bahan baku dengan pemasok tempurung kelapa juga menjamin kontinuitas usaha sehingga produksi dapat berjalan secara konsisten. Perubahan kondisi mitra terlihat jelas, di mana sebelumnya usaha Bathok Koi masih bersifat tradisional dengan keterbatasan teknologi dan sistem manajemen, kini telah berkembang menjadi usaha yang lebih modern, efisien, dan siap bersaing di pasar ekspor. Dengan demikian, kegiatan PkM ini tidak hanya menyelesaikan permasalahan mendasar mitra, tetapi juga memberikan dampak berkelanjutan dalam penguatan kapasitas produksi, manajemen usaha, serta peningkatan daya saing produk berbasis limbah tempurung kelapa.

Abstract

Batik wastewater generated by micro-scale industries typically contains high organic loads, intense coloration, and fluctuating pH, exceeding national discharge limits. This study aims to design, install, and evaluate a simple pilot-scale wastewater treatment plant (WWTP) using a coagulation–filtration–adsorption process for UMKM Batik Ulur Wiji in Indonesia. Wastewater quality was analyzed before and after treatment for pH, BOD, COD, TSS, TDS, turbidity, and color referring to Indonesian Ministry of Environment Regulation No. 5/2014. The results show a substantial improvement in water quality, with COD reduced from 857 to 112 mg/L and BOD from 358 to 68 mg/L. Turbidity decreased from 218 to 14 NTU, and color removal was visually significant. The treated effluent met key parameters for non-potable reuse. A partner satisfaction survey revealed increased environmental awareness, full operational understanding of WWTP, and long-term commitment to system use. This study demonstrates that simple low-cost treatment units are effective for batik wastewater management in micro-industries and provide a replicable model for community-based environmental interventions.
