Abstract

XYZ is a company engaged in the processing of oil and gas, serving as a crude oil storage facility. The issue concerns the workload and work shifts of the employees. This study aims to determine whether there is an impact of workload and work shifts on operator employees. The method used in this study is quantitative. The research results show that the workload has a significant effect on employee work stress, as obtained from the t-test with a significant value of 0.022 < 0.05, which means that the workload has a significant partial effect on work stress. Meanwhile, work shifts do not have a significant effect on employee work stress, as obtained from the t-test with a significant value of 0.196 > 0.05, meaning work shifts do not have a significant partial effect on work stress. This is because the majority of operators in the company have worked for more than 1 year, which means that operators have already adapted to the shift changes. This study is expected to contribute to reducing the factors that can cause work stress among operator employees. Improvement recommendations are proposed to increase unit effectiveness, such as establishing a maintenance schedule, checking and replacing components, and operator training. It is hoped that this research can contribute to increasing the effectiveness of unit use and company productivity.

Abstract

The energy industry, including PT Pertamina Hulu Kalimantan Timur (PHKT), faces serious challenges in managing the fuel supply of Ship X, which is vital for worker mobility, due to the high frequency of deliveries (3-4 times a month) which increases operational costs. This study aims to forecast the  refueling of Ship X using  the Seasonal Autoregressive Integrated Moving Average (SARIMA) model and evaluate the accuracy. The accuracy evaluation was carried out by integrating the Mean Absolute Error (MAE), Mean Absolute Deviation (MAD), and Mean Absolute Percentage Error (MAPE) metrics. Secondary data on the weekly fuel consumption of Ship X from PT Pertamina Hulu Kalimantan Timur (PHKT) Penajam Supply Base (PSB) for the period January to September 2024 was used in this study. Based on the analysis, the SARIMA model (1,1,0)(0,1,1)6 was identified as a statistically significant model and suitable for forecasting. The forecast results for the next 13 weeks, starting from week 40, with an initial prediction of 1794.37 liters. The evaluation of the accuracy of the model resulted in an MAE of 143.66 liters, a MAD of 107 liters, and a MAPE of 8.33%. This accuracy evaluation  provides a deeper understanding of the model's performance, which contributes to more informed fuel inventory management and improved operational efficiency of Ship X.

Abstract

Peramalan kebutuhan HCl di PT. ABC sangat penting untuk menjaga kelangsungan unit operasional demineralisasi. Penelitian ini menganalisis data historis penggunaan HCl dari bulan April 2023 hingga November 2023, dengan menerapkan metode moving average untuk periode 2, 3, 4, dan 5. Analisis ini bertujuan untuk menentukan metode peramalan yang paling akurat dalam memprediksi kebutuhan HCl untuk bulan Desember 2023. Hasil Analisis menunjukkan bahwa metode moving average 4 periode memberikan nilai rata-rata deviasi absolut (MAD) terkecil sebesar 11.6875 dan rata-rata persentase kesalahan absolut (MAPE) sebesar 6%. Hal ini menunjukkan bahwa metode tersebut mampu memberikan prediksi yang lebih tepat dibandingkan dengan periode lainnya. Meskipun moving average 2 periode dan 4 periode menghasilkan nilai peramalan yang sama, perbedaan nilai MAD dan MAPE menunjukkan bahwa penggunaan periode yang lebih panjang dapat mengurangi penyiaran dalam peramalan. Temuan ini memberikan kontribusi penting bagi PT. ABC dalam mengoptimalkan penyediaan HCl dan meningkatkan efisiensi operasional. Rekomendasi untuk penelitian lebih lanjut meliputi penggunaan data historis yang lebih representatif, serta penyesuaian model peramalan sesuai dengan perubahan kondisi pasar dan faktor eksternal yang mempengaruhi proses produksi.

Abstract

Program "Tegur Jika Saya Tidak Aman (TEMAN)” bertujuan untuk meningkatkan keselamatan kerja dengan mendorong budaya saling menegur di antara pekerja ketika menghadapi potensi bahaya. Penelitian ini mengevaluasi implementasi program TEMAN di suatu perusahaan dan mengidentifikasi kendala-kendala yang dihadapi melalui metode USG (Urgency, Seriousness, Growth). Hasil evaluasi menunjukkan bahwa 87,5% pekerja telah mengimplementasikan program, namun terdapat enam kendala utama yang ditemukan termasuk pimpinan yang belum menjadi teladan, preferensi pekerja untuk tidak menerapkan program, serta sosialisasi yang kurang efektif. Ketidakmauan menerima teguran, rasa sungkan dalam menegur, dan kekhawatiran akan menyinggung rekan kerja juga menjadi masalah yang signifikan. Untuk mendapatkan pemahaman lebih mendalam, tiga kendala prioritas dianalisis menggunakan fishbone diagram yang mengidentifikasi faktor penyebab dari aspek manusia, metode, dan proses. Dalam aspek manusia, kurangnya kesadaran pimpinan dan pekerja menjadi sorotan utama. Dari sisi metode, sosialisasi yang kurang efektif diperhatikan, dan pada aspek proses, pelaksanaan program yang tidak teratur berkontribusi pada masalah ini. Berdasarkan hasil analisis, solusi yang diusulkan mencakup peningkatan sosialisasi kepada pimpinan agar dapat berfungsi sebagai teladan bagi pekerja, pemberian penghargaan kepada pekerja yang aktif menerapkan program, serta peningkatan variasi dan efektivitas dalam metode sosialisasi. Implementasi solusi ini diharapkan dapat meningkatkan keberhasilan program TEMAN dan menjaga budaya keselamatan kerja, serta mempertahankan zero LTI (lost time injury) di lingkungan kerja.

Abstract

HR plays a very important role in the success of an organization. To ensure that a job is achieved, the worker's workload should not exceed the worker's capacity to complete a job. Observations were carried out directly on 8 production worker sections carried out for three months at PT. Mulia Jaya Mandiri Balikpapan (PT. MJM) with 10 observations for 1 field of work in each type of production work. The results of the workload survey can be caused by the limited capacity of workers in processing their work or when processing information at PT. MJM, it was found that there were levels of workload experienced by workers, such as a worker who completed 2 jobs simultaneously with limited capacity. Based on the problems above, it is necessary to measure the workload of PT. MJM workers, where this can make the company's performance increase and reduce overtime working hours with the help of the Full Time Equivalent (FTE) method where the first step is to determine worker resources, determine cycle time, determine worker rating factor, determine allowance, calculate normal time and standard worker time, determine the FTE value and after that it is entered into the FTE assessment index the results obtained 2 jobs fall into the overload category, namely purchasing workers and casing rolling operator workers 1 with FTE values ​​​​of 1.29 and 1.39. It is known that the cause of the workload at PT. MJM, namely the lack of worker resources in the production section, due to the purchasing section, and the 2 Machine operator workers (Casing Threading) lacking worker resources coupled with the high consumer demand in November 2024 - January 2025. Recommendations for improvement by rearranging job descriptions for production workers and adding the number of competent and expert production worker resources in purchasing work and casing rolling machine operators, so that they can be more effective and efficient at PT. MJM
