Improving Machine Efficiency at PT PID Ongkowidjojo

Maria Immaculata Prameswari — 2024-12-31

This study aims to enhance equipment effectiveness in the primary cigarette manufacturing process at PT. PID Ongkowidjojo, focusing on Stage 3, a critical production phase with significant downtime due to equipment failures. Using Overall Equipment Effectiveness (OEE) and Failure Mode and Effects Analysis (FMEA), the research identified nine key failure modes affecting interconnected machines. Based on these findings, targeted improvements were implemented, including scheduled maintenance, real-time monitoring, periodic cleaning, and spare parts inventory management. As a result, the OEE value increased from 50.52% to 56.57%, driven by improvements in Availability (71.07% to 79.22%) and Quality Rate (92% to 93.36%), despite a slight decline in Performance Rate (77.20% to 76.25%). This study highlights the importance of integrating OEE and FMEA methodologies to reduce downtime and address equipment inefficiencies. By tackling the Six Big Losses, particularly equipment failures, this approach offers actionable insights for maintaining operational efficiency and fostering continuous improvement in manufacturing systems.

Optimization of Tobacco Warehouse Temperature to Reduce Defects in Hand-Rolled Kretek Cigarette Products at PT XYZ

Natasha Margaretha — 2024-12-31

The quality of tobacco is a critical component in cigarette production, with moisture content standards ranging from 18% to 19% to prevent production issues caused by tobacco being too dry or too moist. At PT XYZ, a cigarette manufacturing company, storage room temperature was identified as a key factor affecting tobacco moisture content. This study aimed to determine the optimal storage room temperature to maintain tobacco quality using quality control techniques and experimental design. A correlation test revealed a very strong negative relationship (91.812%) between storage room temperature and tobacco moisture content. Using a Completely Randomized Design (CRD) and a one-way ANOVA test, the analysis showed that the storage room temperature significantly impacted moisture content. The optimal temperature for maintaining tobacco quality was found to be 21˚C. These findings underscore the importance of precise temperature control in ensuring tobacco quality, contributing to improved production processes and product consistency in the cigarette industry.

Analisis Faktor Penentu dalam Pemilihan Indekos Mahasiswa di Surabaya

Prihono Prihono — 2024-12-31

This study examines the factors influencing students' decisions in selecting boarding houses in Surabaya, an increasingly critical issue as demand for student housing rises post-pandemic. A mixed-method approach was employed, beginning with open-ended questionnaires to identify broad preferences, followed by closed-ended questionnaires to rank key factors. Factor analysis using SPSS revealed three dominant factors: security and environment (33.79%), location and price (22.19%), and facilities (20.47%). Among these, security and environment emerged as the most influential, underscoring the importance of safety and a clean, comfortable setting. Location and price ranked second, with students favoring affordable boarding houses near campuses and essential services. Facilities, including high-speed internet and clean sanitation, also significantly impacted decisions. These findings offer practical insights for boarding house owners to prioritize safety measures, enhance cleanliness, and improve facilities to attract students. While the results align with existing literature on housing preferences, this study is limited by its sample size and focus on Surabaya, which may not generalize to other contexts. Future research could explore additional factors such as parking availability or shared amenities and extend the analysis to other cities for comparative insights. This research contributes to understanding student housing preferences and offers actionable recommendations for managing boarding houses in urban educational hubs.

Perancangan Website untuk Menangani Keluhan Pelanggan di Industri Sepeda

Tania Eka Wardani — 2024-12-31

Salah satu sektor yang memengaruhi perekonomian Indonesia adalah industri manufaktur, termasuk industri sepeda. PT Insera Sena, sebagai produsen sepeda, menghadapi tantangan dalam menangani data penjualan dan keluhan pelanggan yang tersebar dalam file terpisah, sehingga menyulitkan analisis komparatif. Untuk mengatasi hal ini, studi ini merancang sebuah website berbasis metode WebQual yang menganalisis kualitas situs melalui empat dimensi: usability, information quality, service interaction quality, dan overall impression. Data diperoleh melalui survei kuesioner kepada divisi International Business menggunakan skala harapan dan persepsi. Analisis dilakukan menggunakan Gap Analysis dan Importance Performance Analysis (IPA) untuk mengidentifikasi atribut yang perlu diperbaiki. Hasil menunjukkan bahwa dimensi usability memiliki gap sebesar -0,47 dan overall dimension sebesar -0,99, menunjukkan masih terdapat ketidaksesuaian antara harapan dan persepsi pengguna. Atribut yang menjadi prioritas perbaikan adalah Q1, Q2, Q3, Q4, dan Q23, yang berhubungan dengan kemudahan penggunaan dan tampilan situs. Studi ini memberikan panduan bagi perusahaan untuk meningkatkan kualitas website dan kepuasan pelanggan secara efektif.

Towards the X-shaped Person, the Next (Industrial) Leader in the Era of Industry 4.0 and Society 5.0

Gembong Baskoro — 2024-12-31

This paper examines the impact on the development of industry and society known as industry 4.0 and society 5.0. Caused by technological and business pressures influenced by the rapid development of digital technology. Industry 4.0 and society 5.0 require the type of person who has digital literacy as well as leadership abilities to lead the industry in an uncertain market situation that can have an impact on disruption. Therefore, to ensure the sustainability of the industry, the type of person who is able to lead the industry through increasing business pressures and strategic environment is needed. This paper evaluates and assesses three shaped of person called I, T, and X on factors related to industrial sustainability, especially in the future due to industry 4.0. The assessment results show that X-shaped person has the highest score of 3.75 compared to I with a score of 1.31 and T with a score of 2.66. This result is specifically influenced by the leadership factor because it has the highest weighting factor of 0.34 for this assessment. This paper proposes an X-shaped person development method both through internal and external programs such as the Leadership Development Program (LDP) or government leadership program held by the National Resilience Institute of the Republic of Indonesia (Lemhannas RI). It is concluded that the X-shaped person is important to be developed for the sustainability and competitiveness of industry today and in the future.
