Abstract

Along with the rapid development of technology, various types of transportation have experienced increased innovation in shapes, colours,models, and even engines. However, one thing that needs special attention is the number of pollutants or emissions released by vehicles. One effort to reduce emissions is increasing the production of Battery-Based Electric Motorized Vehicles. Battery-based electric vehicles developed in Indonesia include electric cars and electric motorcycles. Among these types of electric vehicles, Indonesian society widely adopts electric motorcycles. However, sales of electric motorbikes were only 15 thousand units, lower than sales of petrol motorbikes which reached 5 million units. This study contributes to understanding further how the community responds to electric motorcycles in detail through sentiment analysis on social media data. Consumer acceptance of electric motorcycles can be seen from the numerous active Twitter users in Indonesia who provide positive and negative comments on the presence of electric motorcycles. Text information based on public comments in Indonesia via Twitter is collected using Sentiment Analysis in R Studio. Twitter comments will be classified into positive, negative, and neutral groups. The results show 63% positive, 21% unfavourable, and 14% neutral opinions. This condition means that Indonesian society accepts and has a supportive opinion of the presence of electric motorcycles. The government and entrepreneurs can use this information to create electric motorcycles that align with the community's preferences.

Abstract

Kualitas layanan kantin kampus merupakan aspek penting dalam mendukung kenyamanan dan kepuasan sivitas akademika. Permasalahan yang diangkat dalam penelitian ini adalah belum optimalnya pemenuhan ekspektasi pelanggan terhadap layanan kantin di beberapa perguruan tinggi di Surabaya. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang memengaruhi kepuasan pelanggan kantin kampus, serta menentukan atribut layanan yang paling berkontribusi terhadap peningkatan kualitas. Metode yang digunakan adalah regresi linear berganda dengan pendekatan kuantitatif melalui penyebaran kuesioner online. Terdapat 86 kuesioner yang berhasil diisi oleh para responden yang terdiri dari mahasiswa, dosen, dan staf kampus. Analisis dilakukan menggunakan perangkat lunak SPSS untuk menguji validitas, reliabilitas, normalitas, multikolinearitas, heteroskedastisitas, dan linieritas data. Hasil penelitian menunjukkan bahwa model regresi mampu menjelaskan 75% variasi kepuasan pelanggan, dengan variabel “Rasa makanan”, “Keramahan pelayan”, dan “variasi menu” yang memiliki pengaruh signifikan secara parsial. Temuan ini memberikan solusi strategis bagi pengelola kantin kampus untuk memprioritaskan pengembangan menu sebagai upaya peningkatan kualitas layanan. Penelitian ini diharapkan dapat menjadi referensi praktis bagi institusi pendidikan tinggi dalam merancang layanan kantin yang lebih responsif terhadap kebutuhan pelanggan.

Abstract

UMKM often face challenges in improving production efficiency and competitiveness, especially in selecting locations and designing optimal production facility layouts. This study aims to design an optimal production facility plan for a fish skin cracker UMKM in Kenjeran Fisherman Village, Surabaya. The focus includes selecting a strategic location for a new branch, designing an efficient facility layout, and streamlining the production process to improve efficiency and market competitiveness. The research methods involve field surveys, interviews, and qualitative analysis to determine a strategic location. The analysis identifies Sukolilo as the optimal site based on proximity to consumers, infrastructure availability, operational cost, and market competition. The facility layout was designed using SketchUp software with a straight-line material flow approach to minimize material movement and reduce production time. This study is expected to provide practical benefits for UMKM in optimizing production processes and enhancing operational efficiency, as well as serving as a reference for future research.

Abstract: Ngulan Wetan Village in Pogalan Sub-district, Trenggalek, has significant potential from organic waste such as rice husks, sawdust, dry leaves, and corn husks. Unfortunately, this waste is often burned and not utilized properly, causing environmental pollution. Meanwhile, fuel prices like LPG and charcoal continue to rise. To address this issue, a team from the Industrial Engineering Department at Universitas Katolik Darma Cendika conducted training on making briquettes from organic waste. The training covered all production steps, from raw material collection to briquette molding and drying. The technology used is simple and based on local resources. As a result, participants were able to produce an average of 12 kg of briquettes per month, exceeding the initial target, with part of the production sold, increasing household income by 10–15%. The program also encouraged behavioral changes in waste management and raised awareness about renewable energy and environmental sustainability. Keywords​: ​​Soap,Waste Cooking Oil, Environment
