Abstract

This study evaluates the effectiveness of a Sodium Metabisulfite (SMBS) packaging machine at PT. DKJ using Overall Equipment Effectiveness (OEE) and Fault Tree Analysis (FTA). OEE was employed to assess machine performance through availability, performance, and quality indicators, while the Six Big Losses framework was used to identify major sources of productivity loss. Furthermore, FTA was applied to determine the root causes of dominant losses affecting machine effectiveness. The study utilized production data, direct observations, interviews, and company records collected from December 2024 to May 2025. The results indicate that the average OEE value of the packaging machine was 63.26%, significantly below the international benchmark of 85%, with low availability and performance as the primary contributors. Six Big Losses analysis revealed that breakdown losses and setup and adjustment losses were the most dominant factors. FTA identified component failure, inadequate preventive maintenance, operator-related errors, and complex setup procedures as the main root causes. This study proposes structured preventive maintenance, operator training, standardized operating procedures, and improved production–material coordination to enhance machine effectiveness and ensure sustainable production performance.

Abstract

This study aims to evaluate and improve the effectiveness of the granulator machine at the NPK Phonska I Plant of PT Petrokimia Gresik through an integrated Overall Equipment Effectiveness (OEE) and Fault Tree Analysis (FTA) approach. The granulator machine frequently fails to achieve the 2024 production target of 37,500 tons per month due to high downtime (89.24 hours/month) and defective products reaching 17,847 tons annually. The research applies OEE to calculate availability, performance efficiency, and quality rate, followed by Six Big Losses classification and FTA to determine the fundamental causes of machine underperformance. The findings show that the average OEE is 62.1%, significantly below the world-class benchmark of 85%, with the largest losses coming from equipment failure (49.00%) and reduced speed losses (37.75%). The novelty of this research lies in the integration of OEE–FTA with additional correlation analysis between downtime and defect ratios and the identification of heat-related and material-variability effects specific to fertilizer granulation. Scientifically, this study contributes a structured improvement framework tailored for the national fertilizer industry, offering evidence-based maintenance strategies and operational insights to support the company’s effort in achieving world-class machine effectiveness.

Abstract

Tata letak fasilitas berperan penting dalam menjaga kelancaran aliran material dan meningkatkan efisiensi proses produksi. Penataan fasilitas yang kurang tepat dapat menyebabkan jarak perpindahan material menjadi panjang serta terjadinya kepadatan lintasan, dan konflik pergerakan kendaraan yang berpotensi menyebabkan bottleneck. PT XYZ sebagai perusahaan yang bergerak di sektor logistic pupuk, menghadapi kendala pada area produksi dan pergudangan yang disebabkan oleh pengaturan jarak antar stasiun kerja serta alur material handling yang belum tertata secara optimal. Penelitian ini dilakukan untuk menyusun kembali tata letak fasilitas produksi dan gudang dengan menerapkan metode ARC dan FTC. Data diperoleh melalui observasi langsung dan data dari perusahaan, kemudian dianalisis dengan perhitungan koordinat titik tengah, evaluasi aliran forward dan backward, serta analisis jarak lintasan. Hasil penelitian menunjukkan peningkatan persentase aliran forward dari 58% menjadi 82,9% dan penurunan backward dari 22% menjadi 17,7%, disertai peningkatan efisiensi jarak lintasan sebesar 13,9%. Hasil ini menunjukkan bahwa penerapan ARC dan FTC mampu meningkatkan efisiensi tata letak fasilitas secara efektif.

Abstract

Proyek pembangunan perluasan gedung PT Sika Indonesia melibatkan serangkaian aktivitas berisiko tinggi seperti pekerjaan di ketinggian dan penggunaan alat berat, sehingga menuntut adanya evaluasi risiko yang sistematis. Penelitian ini bertujuan untuk mengevaluasi risiko kecelakaan kerja di proyek tersebut dengan mengintegrasikan metode Hazard Identification, Risk Assessment, and Risk Control (HIRARC) dan Job Safety Analysis (JSA), sebuah pendekatan yang belum banyak diterapkan pada proyek perluasan industri kimia untuk analisis yang lebih mendalam. Menggunakan metode deskriptif dengan pendekatan studi kasus, dimana data primer dikumpulkan melalui observasi lapangan dan diskusi, teridentifikasi 12 aktivitas kerja utama di dua area kritis. Dari hasil penelitian, analisis menunjukkan adanya lima aktivitas dengan tingkat risiko Ekstrem, dua aktivitas berisiko Tinggi, empat sedang, dan satu rendah. Risiko dominan yang teridentifikasi adalah jatuh dari ketinggian, tertimpa material berat, dan kegagalan fungsi alat angkat angkut. Integrasi metode HIRARC dan JSA dalam penelitian ini berhasil memetakan dan memprioritaskan risiko secara komprehensif, dari level makro hingga detail operasional. Rekomendasi pengendalian yang dihasilkan menekankan pentingnya pendekatan sistemik yang tidak hanya bergantung pada Alat Pelindung Diri (APD), tetapi mencakup perbaikan prosedur kerja, peningkatan kompetensi personel, dan pengawasan yang konsisten untuk menekan risiko ke tingkat yang dapat diterima serta membangun budaya keselamatan yang berkelanjutan.

Abstract

Mesin Mobile Bagging Unit (MBU) merupakan layanan utama PT. ABC yang berfungsi sebagai sarana pengantongan pupuk ZA Plus dalam mendukung kelancaran distribusi produk. Mesin ini berperan penting dalam rantai penyimpanan dan pengelolaan komoditas, baik dalam bentuk curah maupun kemasan. Namun, dalam beberapa bulan terakhir, operasional MBU mengalami peningkatan downtime akibat faktor internal seperti kerusakan komponen dan gangguan mesin pewarna, serta faktor eksternal berupa keterlambatan pasokan bahan baku. Usia operasional mesin yang telah mencapai lima tahun juga berkontribusi terhadap penurunan performa dan ketidakstabilan laju produksi. Penelitian ini bertujuan untuk mengevaluasi efektivitas operasional mesin MBU serta mengidentifikasi sumber utama ketidakefisienan yang ditandai oleh tingginya downtime dan fluktuasi kecepatan produksi. Data penelitian meliputi catatan operasi, perawatan, hasil produksi, dan produk cacat pada periode Mei–Oktober 2025. Metode Overall Equipment Effectiveness (OEE) digunakan untuk mengukur efektivitas mesin berdasarkan availability, performance, dan quality, sedangkan Failure Mode and Effect Analysis (FMEA) diterapkan untuk mengidentifikasi potensi kegagalan dan menentukan prioritas perbaikan. Hasil analisis menunjukkan nilai OEE rata-rata sebesar 47,12%, masih jauh di bawah standar kelas dunia 85%, dengan Performance Efficiency sebagai faktor terendah. Analisis Six Big Losses mengungkapkan bahwa kerugian terbesar berasal dari reduced speed losses dan breakdown losses. Sementara itu, FMEA mengidentifikasi jarum jahit, nepel pisau, dan looper sebagai komponen dengan risiko tertinggi. Berdasarkan temuan tersebut, disarankan penerapan perawatan preventif terencana, penggantian komponen kritis secara berkala, serta pemantauan kondisi mesin secara waktu nyata guna meningkatkan keandalan dan produktivitas mesin MBU secara berkelanjutan.

Abstract

Computer Numerical Control (CNC) turning is one of the most widely applied precision machining technologies in modern manufacturing, where surface quality is a key determinant of product performance and reliability. Surface roughness (Ra) is recognized as one of the most critical parameters for evaluating machining results. However, reliance on operator experience in selecting machining parameters often leads to inefficiencies and inconsistent surface quality, indicating the need for more accurate predictive approaches. This study proposes an Artificial Neural Network (ANN)-based model to predict surface roughness in CNC turning using two distinct experimental configurations. The first experiment (Exp1) employs three identical factor variations, whereas the second experiment (Exp2) incorporates different factorial combinations to introduce broader variability. The developed ANN architecture consists of four dense layers with ReLU and LeakyReLU activation functions, complemented by dropout layers to mitigate overfitting arising from the relatively small dataset. The results show that the ANN model effectively learns the nonlinear relationships between machining parameters and Ra values. Furthermore, the model achieves higher predictive accuracy in Exp2, likely due to its more structured parameter variations. Overall, the findings demonstrate that ANN-based prediction provides a promising and efficient approach for enhancing accuracy in surface quality assessment within CNC turning operations.   Keywords-  Artificial Neural Network (ANN); CNC Turning; Surface Roughness.

Abstract

The layout of facilities in the industrial world greatly affects the production process of a product. If the spatial layout used is good and appropriate, it will indirectly save distance, costs, time, and effort. Community service activities are carried out in partnership with SMK Manbaul Ulum. These activities aim to provide learning about facility layout to minimize production process time. The expected outcome of these activities is that students will be able to understand how to reduce excessively long production times and increase the number of products in a business unit, which impacts student productivity. The implementation methods include delivering material, simulating the production process layout, and conducting Q&A discussions. As a result, the activities are able to enhance students' understanding of the importance of layout in production facilities. Students can also simulate the production process to evaluate the existing layout in order to minimize production time. This activity has an impact on decision-making and problem-solving.

Abstract

This study aims to answer the question of why someone uses FDA by using independent variables, namely special benefits, time saving, delivery experience, reviews and price value for reusing applications mediated by customer satisfaction. Total of 179 Generation Z respondents participated in this study. The design in this study uses quantitative and analytical techniques using PLS tools. Interesting findings in this study were successfully identified. This study found that time saving that is considered to be able to make people satisfied and return to reuse the FDA proved unacceptable, which means that in Generation Z there is perceived dissatisfaction with the time given by the FDA, and Generation Z does not need to save time in ordering food online, time saving is not a reason for them to reuse the FDA. In this case, online application food delivery service providers  must consider other causes that make them satisfied and willing to use the FDA application again, for example,  the special benefits offered, and the experience in ordering food, reviews and price values that are highly regarded by consumers, especially in generation Z which has an effect on customer satisfaction which in the end satisfaction affects the reuse of the application.
