Abstract

Rapid industrial growth worldwide, especially in Indonesia, has posed threats to the environment and public health. Environmental pollution is mainly caused by domestic wastewater generated from households, businesses, and residential areas. Types of domestic wastewater that need attention include human feces or waste, urine, detergents, soaps, and food scraps. Wastewater pollution from households has become increasingly critical due to the rise in household activities and urbanization in Indonesia. To address the issue of household wastewater pollution, efficient wastewater management systems and increased public awareness are necessary. The implementation of filtration technology is a crucial solution to maintain water quality. Filtration is a process of separating solid particles from liquids using filtering media or screens. The results of filtration can produce cleaner and safer water, and this technology continues to be developed to meet the demand for high-quality and safe water. This experiment aims to create a simple filtration bottle using recycled materials and demonstrate its effectiveness in reducing the content of household wastewater. The filtration process resulted in a 79.32% reduction in COD content, an 85% reduction in TSS content, and a 91.3% reduction in turbidity. By utilizing recycled materials and efficient filtration technology, it can help mitigate the negative impact of domestic wastewater on the environment. In conclusion, the utilization of recycled materials as a simple filtering tool can reduce the content of household wastewater and contribute to maintaining a clean and healthy environment. The awareness and participation of the community in using this filtering tool can have a greater positive impact on the environment.

Abstract

The prospect of success of a manufacturing project is determined by the results of feasibility tests such as investment and operations. In its implementation, the feasibility test is often constrained by several things such as data entry errors, calculation errors, and a long calculation time. The ideal solution that can be used to solve these three obstacles is to design an offline and stand-alone desktop-based feasibility calculation application. This research uses the SDLC Waterfall method and User Acceptance Test (UAT) based on questionnaires and scenario tests. In the design and coding completion phase, the SDLC waterfall approach is combined with generative AI to speed up the application design time. As a result, a calculation application named Manufurrt has been created with an interactive executable file format and is able to provide the same calculation results between the expected spreadsheet and the real calculation results from the application.

Abstract

Distribusi gas LPG 3 Kg memerlukan perencanaan rute yang efisien untuk menekan biaya operasional, menghemat waktu, dan meningkatkan keamanan pengiriman. Penelitian ini bertujuan untuk mengoptimalkan pemilihan rute terpendek distribusi gas LPG 3 Kg dengan menerapkan Algoritma Sweep berbasis Python pada kasus Capacitated Vehicle Routing Problem (CVRP). Data yang digunakan meliputi lokasi pelanggan, jarak antar titik, dan kapasitas angkut truk. Algoritma Sweep digunakan untuk mengelompokkan pelanggan berdasarkan sudut polar relatif terhadap depot, dilanjutkan dengan penentuan urutan kunjungan yang meminimalkan jarak tempuh sambil memenuhi batas kapasitas kendaraan. Hasil optimasi menunjukkan bahwa metode ini mampu menghasilkan tiga rute distribusi dengan total jarak tempuh 98,7 km, mengalami pengurangan sebesar 26,18 km atau sekitar 21% dibandingkan kondisi awal yang mencapai 124,88 km. Selain itu, jumlah armada dapat ditekan menjadi tiga truk tanpa melanggar batas kapasitas angkut. Implementasi berbasis Python memungkinkan proses penghitungan dan pemodelan rute dilakukan secara cepat, akurat, dan dapat diulang untuk berbagai skenario distribusi.

Abstract

The nglowongi process is one part of the batik process, which is making patterns on mori. As technology develops, this process is replaced by machines that apply CNC technology, namely the CNC rotary bed. In its implementation, obstacles were found such as failure to form motifs that have perfect angles on the fabric. There are many possible factors that cause the failure, but the authors focus on the limiting factors on the speed and acceleration of the stepper motor movement and the design angle of the motif. The purpose of this research is to optimize the input setup (speed and acceleration) on GRBL during the process of making angular motifs on batik cloth. The method used is the Taguchi method and two way-ANOVA. The results of this study indicate that the optimal combination of motif design angle, speed and acceleration is 91°-180°, 833.33 mm/s or 500 mm/min respectively and the input acceleration is 4000 mm/s2

Abstract

Perkembangan zaman yang cepat menuntut efisiensi dalam segala aktivitas, termasuk dalam penggunaan kendaraan bermotor. Tingginya kepadatan penduduk telah meningkatkan penggunaan kendaraan, yang pada gilirannya meningkatkan emisi karbon monoksida (CO) dan mengancam kualitas udara. Gas CO yang dihasilkan oleh kendaraan bermotor merupakan pencemar udara berbahaya, dengan dampak langsung dan tidak langsung pada kesehatan manusia serta kualitas udara. Emisi CO, terutama dari kendaraan bermotor, telah menjadi penyebab utama penurunan kualitas udara di berbagai daerah. Standar emisi gas CO pada knalpot adalah 249.24 ppm. Oleh karena itu, diperlukan solusi untuk mengurangi dampak emisi gas kendaraan bermotor pada lingkungan.Salah satu solusi adalah penggunaan tembaga sebagai katalisator, yang dapat mengurangi kadar CO dalam gas buang kendaraan. Metode ini melibatkan penambahan lapisan sekat tembaga di dalam knalpot, serta plat tembaga di ujung masukan gas kendaraan ke knalpot. Saat gas kendaraan melewati knalpot, reaksi katalisis tembaga mengurangi kadar CO dalam gas buang. Penggunaan teknologi ini diharapkan dapat mengubah emisi menjadi gas yang lebih ramah lingkungan, mengendalikan polusi udara yang berasal dari kendaraan, dan meningkatkan kualitas udara. Dengan demikian, penggunaan katalisator tembaga di dalam knalpot menjadi solusi yang efektif untuk mengurangi emisi CO dari kendaraan bermotor, memenuhi standar emisi, dan mendukung upaya menjaga lingkungan dan kesehatan manusia.
