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

Perajangan merupakan proses paling penting dalam menentukan kualitas produk keripik buah apel yang akan dihasilkan. Sejalan dengan hal tersebut, hasil rajangan sangat bergantung pada kondisi alat perajang maupun keahlian dari penggunanya. Para produsen keripik buah apel di Desa Tulungrejo Kecamatan Bumiaji Kota Batu masih menggunakan alat perajang manual yang mempunyai beberapa kekurangan. Sehingga perlu adanya pengembangan untuk menghasilkan performa mesin perajang yang sesuai dengan kebutuhan produsen tersebut. Penelitian ini bertujuan untuk mengembangkan mesin perajang buah apel sesuai dengan Voice of Customer (VoC) atau kebutuhan dan keinginan produsen keripik buah apel. Metode pengembangan yang digunakan adalah Quality Function Deployment (QFD) dengan alat bantu representatif   berupa matriks House of Quality (HoQ). Di dalam HoQ, customer berharap mesin yang dikembangkan dapat menghasilkan tebal rajangan sesuai standar (3-5 mm) serta memiliki kemampuan yang lebih baik dari alat yang sudah ada disana. Dari hasil concept screening, terpilih konsep dengan kombinasi putaran rpm diatur menggunakan dimmer, ketebalan rajangan diatur dengan baut tekan, tuas pengarah menggunakan pegas tarik dan model mesin tipe horizontal. Mesin ini dirancang mempunyai dimensi minimalis yaitu sebesar 616 x 430 x 430 mm serta dengan komponen yang sederhana sesuai customer requirements pada HoQ. Kapasitas dari mesin ini sebesar 80 kg/jam dengan konsumsi daya listrik sebanyak 150 watt.

Abstract

Tourism development is an effort to create added value in all aspects of the tourism sector, starting from facilities and infrastructure, tourist objects and attractions, and other aspects. One of the tourism developments is the Lembung Mangrove Ecotourism in Lembung Village, Galis District, Pamekasan Regency. The problem with developing Lembung Mangrove Ecotourism in Lembung Village is that it has not properly accommodated visitor needs, such as the existence of good tourist facilities. Based on this, it is necessary to develop sustainable ecotourism. The aim of this community service (CS) is to develop Lembung Mangrove Ecotourism facilities in Lembung Village so that the local economy and community empowerment increase. The types of facilities and infrastructure developed by the CS Polinema team for the community partnership scheme at CS locations are in the form of science and technology diffusion of appropriate technological equipment, namely: deep fat frying machine. The PPM results are then awarded to Tourism Awareness Group (Pokdarwis) “Sabuk Hijau”.

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

The problem lies in the lack of empowerment of residents in making Charcoal Ash Briquette Machine and their trials. This community service activity aims to guide residents of Saptorenggo, Pakis, Malang in making and testing effective Charcoal Ash Briquette Machine. The method applied is a discussion with residents in the design of the Charcoal Ash Briquette Machine with the working principle of pressing with a rolling roller on a mold plate, making the machine using available and affordable technology, assembly, and testing. The results of community service are in the form of a Charcoal Ash Briquette Machine with a capacity of 45 kg / hour with cylindrical briquette products with a diameter of 8 mm or 12 mm through collaboration between residents of Saptorenggo, Pakis, Malang and the State Polytechnic of Malang (Polinema), so that synergy is established between Polinema and residents of Saptorenggo, Pakis, Malang in producing briquettes from effective wood charcoal ash.

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.

Abstract

Berdasarkan analisis kebutuhan dan potensi pasar, Program Pengabdian Kepada Masyarakat ini mengusulkan solusi strategis bagi UKM Mie Mahkota di Pasuruan. Tingginya permintaan mie di Malang, baik sebagai daerah dingin maupun kawasan pendidikan, belum dapat dipenuhi akibat kendala jarak yang membatasi daya tahan produk (<24 jam). Solusi yang ditawarkan adalah pemberian mesin Vacuum Sealer DZ 500 2SA. Alat ini terbukti efektif, teruji pada UKM Mie Pangestu yang produknya (mie bumbu dan mie gulung) mampu bertahan hingga 9 hari di suhu ruang tanpa bahan pengawet, dengan rasa dan bau tetap standar. Dengan teknologi ini, produk Mie Mahkota dapat bertahan lebih lama, memungkinkan ekspansi pemasaran ke Malang. Program dilaksanakan bertahap: pengadaan alat, pelatihan penggunaan, dan pembenahan manajemen pemasaran. Dampak yang diharapkan meliputi peningkatan volume produksi, perluasan pasar, peningkatan keuntungan, serta penyerapan tenaga kerja baru di Pasuruan dan Malang.
