Usability Evaluation of the Mendeley Website Using System Usability Scale (SUS)
type: item
description: A scientific paper is a writing that follows scientific principles and research ethics, supported by reference citations. Mendeley facilitates reference management; however, many students are not yet accustomed to using it. This study aims to evaluate the use of Mendeley and identify areas for improvement. The research method employed usability testing with the System Usability Scale (SUS) instrument. Statistical testing was also conducted, involving 24 students from the Industrial Engineering Program at Udayana University. Participants completed five task scenarios related to Mendeley features. Data on system effectiveness and efficiency were collected during the trials. The results show that Mendeley achieved an SUS score of 72.1, indicating an acceptable usability level with a Grade C and a “good” adjective rating. System effectiveness reached 100%, with all participants completing all tasks. Efficiency evaluation showed a rate of 0.177 goals/second, meaning users could complete 0.177 tasks per second. Statistical analysis indicated no significant differences in SUS scores or system efficiency based on gender. Furthermore, there was no correlation between SUS scores and system efficiency. These findings suggest that usability ratings are not directly related to system efficiency.

Optimasi Peramalan Penjualan Perishable Product dengan Metode Time Series Menggunakan Software POM-QM
type: item
description: Perishable products are items with short shelf life. In this study, perishable product being analyzed has only one day shelf life. Therefore, an accurate forecast method is needed to avoid shortage and waste. Shortage occurs whend demand exceeds the company’s stock, resulting potential loss sales. Waste occurs when demand is lower than available stock, leading to overstock. Excexx inventory causing losses and reduces profit. This study is conducted using 2 scenarios, as shown in Table 1. Scenario 1 uses 60 days od data, while scenario 2 separates data between weekend and weekdays. Data abalysis was performed using time series method with POM-QM software. The best method is determined based on lower MAD, MSE, MAPE. The result of this study sho that separating the historical data between weekends and weekdays (scenario 2) leads to better forecasting accuracy, indicated by a lower MAPE compared to scenario 1. For weekend forecasting, the best method is exponential smoothing (Scenario 2A.2) with MAPE 10,05%. For weekday forecasting, the best method is moving average (Scenario 2B.1) with MAPE 15,40%. The research is expected to serve as a reference for company in selecting appropriate forecasting method. The goal is to help company anticipate shortage and waste in perishable products. The recommendation for company is automate the separation of weekend and weekday data to accelerate the forecasting prosess. Future research recommendation is use other forecast method and software, then consider factor consists of shelf life, promotion, national holidays, or national event.

Peningkatan Kapasitas Mesin Rubber Sheet Calendar Menggunakan Discrete Event Simulation: Studi Kasus di Industri Pengolahan Karet
type: item
description: Increasing production capacity is one of the key strategies to maintain the competitiveness of tire companies in an increasingly dynamic and competitive market. One of the critical machines in the tire production process is the Rubber Sheet Calender, which currently has a capacity of only 2700 Tires Per Day (TPD). However, based on the sales forecast for 2025, the required production capacity is expected to reach 3000 TPD. This study aims to analyze and enhance the capacity of the Rubber Sheet Calender machine using the Discrete Event Simulation (DES) approach. Data were collected through direct observation, time studies, and interviews with machine operators and production supervisors. A simulation model was developed to represent the actual condition (as-is), and improvement scenarios were tested, including adding labor, increasing buffer capacity, and reducing setup time. The simulation results show that a combination of improvements can significantly increase throughput by increasing machine speed from 4.65 to 6.31 (a 36% increase) and raising production capacity from 3360 to 4962 (a 59% increase). Thus, the improvement recommendations using DES have proven to be an effective decision-support tool for enhancing production capacity.

Quality Improvement and Defect Control in Food Packaging Industry with DMAIC Approach
type: item
description: Low product packaging quality in food products can negatively impact customer satisfaction and company performance. This research aims to improve the packaging quality of Shanghai Atom Peanut products using the Six Sigma method with the DMAIC approach, consisting of Define, Measure, Analyze, Improve, and Control phases. The research identified two main critical to quality factors: nonconforming product weight and poor sealing quality, which together contributed 84.3 % of total defects. Before improvement, several days showed out-of-control data, with 814 defective units out of 6480 inspected. Improvements were implemented using the FMEA method, including product standardization, sensor installation, and enhanced operator supervision. After improvement, defects were reduced to 299 units, and all data points were within control limits. The RPN decreased significantly, with D1 dropping from 336 to 175 and D2 from 294 to 100. A paired T-test confirmed the improvements were statistically significant with a P-Value of 0.001. This shows that the DMAIC approach effectively reduces defects and supports sustainable process control. For future research, evaluating the effectiveness of the Six Sigma approach across various packaging types, such as metallised packaging, carton boxes, and cans, may contribute to the development of a more efficient and market-orientated packaging process.

Perencanaan Dan Pengendalian Persediaan Bahan Baku Produksi Underframe Kereta Menggunakan Metode Material Requirement Planning(MRP)
type: item
description: Penelitian ini bertujuan untuk menganalisis sistem perencanaan dan pengendalian persediaan bahan baku underframe pada produksi Kereta 16TS KRL KCI di PT. ABC Permasalahan utama yang dihadapi perusahaan adalah ketidakteraturan pasokan bahan impor yang menyebabkan keterlambatan produksi dan peningkatan biaya persediaan. Untuk mengatasi hal tersebut, digunakan pendekatan Material Requirement Planning (MRP) sebagai metode perencanaan kebutuhan material yang mempertimbangkan data Bill of Material (BOM), jadwal produksi (Master Production Schedule), harga bahan baku, dan data inventori. Penelitian ini juga membandingkan tiga metode lot sizing, yaitu Lot for Lot (LFL), Economic Order Quantity (EOQ), dan Periodic Order Quantity (POQ), guna menentukan metode yang paling efisien dalam menekan biaya persediaan. Analisis dilakukan dengan menghitung total biaya pemesanan dan penyimpanan untuk masing-masing metode. Hasil perhitungan menunjukkan bahwa metode POQ memberikan total biaya persediaan terendah sebesar Rp21.461.454, sehingga dinilai paling optimal untuk diterapkan di PT ABC. Metode EOQ juga terbukti lebih efisien dibandingkan LFL, namun belum mampu mengungguli POQ. Penerapan MRP secara keseluruhan terbukti efektif dalam membantu pengambilan keputusan pengadaan bahan baku yang lebih terstruktur, tepat waktu, dan hemat biaya. Penelitian ini memberikan kontribusi dalam optimalisasi pengelolaan persediaan, terutama pada industri manufaktur yang bergantung pada pasokan bahan baku impor.

type: item
description: Penelitian ini bertujuan untuk menganalisis sifat material SB 171 C70600 dalam upaya meminimalisir risiko korosi pada komponen channel tube bundle E-3-05 A&C di kilang minyak. Pada awalnya, material SA 105 (carbon steel) direncanakan sebagai bahan fabrikasi, namun terbukti tidak cocok untuk lingkungan korosif, sehingga dipilih SB 171 C70600 sebagai pengganti. Metode yang digunakan meliputi observasi langsung, wawancara teknis, dan studi literatur terhadap spesifikasi ASME BPVC 2023. Hasil menunjukkan bahwa SB 171 C70600, yang mengandung tembaga dan nikel, memiliki ketahanan tinggi terhadap korosi, khususnya dalam lingkungan air laut, serta konduktivitas termal yang baik. Dibandingkan SA 105, SB 171 C70600 lebih unggul dari sisi ketahanan terhadap korosi, meskipun memiliki kekuatan mekanik yang lebih rendah. Pemilihan SB 171 C70600 pada bagian channel terbukti mampu menjaga efisiensi perpindahan panas, mengurangi risiko kebocoran, dan memperpanjang umur pakai komponen. Dengan demikian, penggunaan material ini sangat direkomendasikan untuk aplikasi heat exchanger yang bekerja dalam kondisi lingkungan korosif.

Analisis Pengaruh Perendaman Benda Uji Terhadap Mutu Beton Menggunakan Metode Statistical Quality Control di PT CAW
type: item
description: Among the various factors that can impact the strength of concrete, the curing method is a key factor. This treatment aims to maintain moisture on the concrete surface, allowing the hydration process to run optimally. Generally, hydration lasts for 28 days, allowing the concrete to reach a strength that meets the established quality standards. However, various conditions in the field are one of the factors that prevent curing from being carried out perfectly. In this study, the researcher wanted to show how the curing process affects the strength of the resulting concrete. The test used concrete samples with curing ages of 7, 14, and 28 days, along with cylindrical test objects. The test results showed that the compressive strength of the concrete increased with increasing curing age, namely 24.11 MPa (7 days), 28.42 MPa (14 days), and 32.56 MPa (28 days), meeting the design quality of 30 MPa. SQC analysis was carried out using the I diagram and MR diagram for each age group of test objects.

Analisis Perencanaan Penambahan Pembangkit Tegangan Menengah di PT XYZ
type: item
description: The availability of a reliable and sufficient electricity supply is a crucial factor in supporting economic growth and societal activities. PT XYZ, as the state-owned company responsible for electricity generation and distribution in Indonesia, faced challenges in maintaining the balance between electricity supply and demand, including in the Bali region. As electricity consumption continued to increase, proper planning was required for managing the power system, particularly in the medium-voltage subsystem. This study aimed to forecast the peak load for the year 2025 and analyze the need for additional generation capacity in the Bali Subsystem. The method employed was Double Exponential Smoothing (DES), with parameter optimization for α and β using the Solver feature in Microsoft Excel to enhance forecasting accuracy. The data used consisted of monthly peak load values from 2024. The forecasting results indicated that the Solver method produced a peak load estimate of 1,287 MW with a MAPE value of 1.50%, which was more accurate than the initial DES method that yielded a MAPE of 5.91%. Meanwhile, the current generation capacity of 1,388 MW leaves only a 101 MW reserve margin, which is below the minimum safety threshold of 130 MW. This condition highlighted the importance of adding medium-voltage generation capacity to maintain the reliability of the Bali power system in the face of potential disturbances and future demand increases.

Penerapan Metode Lean Six Sigma Dmaic Dalam Optimalisasi Overcapacity Gudang Chemical Plant Marunda PT Smart Tbk.
type: item
description: PT SMART Tbk is one of the largest palm oil processing companies in Indonesia. In its production process, the company uses various types of chemicals stored in a dedicated chemical warehouse. Data shows that the pallet capacity at the chemical warehouse in the Marunda Plant frequently reaches full capacity or even overcapacity, which poses a risk of disrupting production flow, such as delays in the movement of materials and accumulation of stock. This study aims to identify the types of waste that contribute to overcapacity and determine the root causes of the problem. The research is limited to the chemical warehouse at the Marunda Plant, focusing on inbound activities for flavor products (code VO16745) and outbound activities for ingredients (code Salt 300265). Based on the analysis using Process Activity Mapping and Value Stream Mapping, the waste level in warehouse operations was found to be 56%, with a total cycle time of 3,528 seconds and a value-added time of 1,536 seconds. This waste directly contributes to overcapacity and decreases warehouse efficiency. Using the Lean Six Sigma DMAIC approach, the root causes were identified through Fishbone Diagram and Root Cause Analysis. The main contributing factors include large vendor packing sizes and minimum order quantities (MOQ), increasing annual demand, limited manpower, narrow warehouse space, small unloading doors, narrow aisles, and a lack of pallets and shelves. As a solution, it is recommended to expand the warehouse area, add more operators, enlarge the unloading doors, and increase the number of pallets and shelves to optimize operations and reduce the risk of overcapacity.
