Abstract

PT. XYZ is one of the companies that has a machine shop department which is an environment where machinery and a form of subtractive manufacturing are carried out. Machine operator workers do their work for 8 hours per day with 2 breaks and less muscle stretching during their work activities. These activities cause operators to experience complaints of fatigue, discomfort, aches and pains in several parts of the body which can cause the risk of musculoskeletal disorders (MSDs). Based on these problems, an analysis of work posture was carried out using the Rapid Entire Body Assessment (REBA) method because it can assess the risk to all parts of the body. This study was conducted on the activities of grinding and inspection operators. Based on the results of the study with the calculation of the REBA score, it is known that the activities of the grinding operator got a score of 10, and the inspection operator got a score of 9, each of which has a high risk level and requires improvement. Proposals for improving the work posture of operators with recommendations for chair and table aids.

Abstract

PT. Pertamina is a company engaged in the Oil and Gas (MIGAS) industry engaged in drilling. This study analyzes how the existing conditions of B3 waste management resulting from drilling activities are carried out. The research uses the Guttman Scale Scoring method. The results of the study using the guttman scale scoring method show that the existing condition of B3 waste management at PT. Pertamina received a total percentage recapitulation of 45% in the "Adequate" category. The recommendation for improving B3 waste reduction activities is to process B3 waste such as used lubricants (used oil) into diesel as fuel through the B3 waste recycling process.

Abstract

Sampah merupakan salah satu permasalahan yang cukup menyita perhatian di Indonesia. Penanganan dan pengelolaan sampah semakin kompleks dan rumit seiring dengan semakin kompleksnya volume, jenis, dan komposisinya. Sampah yang terus menerus di tumpuk menyebabkan banyak masalah, oleh karena itu perlu pengelolaan sampah berbasis 3R Reduce, Reuse, dan Recycle (3R). Perilaku masyarakat yang tadinya “membuang” limbah, harus diubah menjadi “mengelola” limbah. Gerakan Mahasiswa Sadar Limbah (MASALIM) yang bertujuan untuk mengedukasi, memotivasi, dan menginisiasi masyarakat dalam melaksanakan 3R. Gerakan ini akan diawali dengan sosialisasi dan edukasi kepada mahasiswa STT Migas Balikpapan untuk menjadi kader MASALIM yang nantinya akan di implementasikan di masyarakat. Gerakan MASALIM dilanjutkan dengan sosialisasi dan edukasi kepada masyarakat dan pembersihan limbah di area pantai Dusit Balikpapan. Dari hasil pembersihan sampah, jenis sampah yang berhasil dikumpulkan di dominasi dengan plastik yaitu sebanyak 129,7 Kg dan jenis limbah lain yang terkumpulkan yaitu kayu, ranting dan daun, pakaian bekas dan pampers, kaca (botol dan serpihan), kaleng dan metal, dan Styrofoam. Gerakan pembersihan dan Pengelolaan limbah berbasis masyarakat dengan konsep 3R diharapkan untuk mengurangi limbah dari sumbernya, mengurangi pencemaran lingkungan, memberikan kontribusi kepada masyarakat dalam bidang kesehatan dan ekonomi, serta mengubah perilaku masyarakat terhadap limbah.

Abstract

Dalam berbagai sektor industri seperti industri minyak dan gas pengambilan sampel merupakan komponen penting dalam pengawasan kualitas produk. Pengambilan sampel yang tepat dapat membantu dalam memantau proses produksi. Pengambilan sampel manual memiliki sejumlah masalah potensial, seperti kelalaian operator, teknik pengambilan sampel, dan seringkali lebih memakan waktu. Seiring perkembangan zaman dan kemajuan teknologi di era globalisasi yang makin meningkat, salah satu teknologi yang digunakan pada industri minyak dan gas bumi dalam pengambilan sampel crude oil adalah automatic inline sampler (AIS). Tentu perubahan ini sangatlah berpengaruh dari segi meningkatnya efisiensi waktu, tenaga dan lain – lain dalam pengambilan sampel. AIS (Automatic Inline Sampler) merupakan salah satu alat yang perannya sangat vital dalam membantu atau mendukug operator dalam pengambilan sampel minyak mentah (crude oil). Karena dengan adanya AIS ini operator dapat memonitoring dari kejauhan dan pengambilannya juga dilakukan secara representatif. Dalam pengoperasian AIS ini nantinya akan dilakukan perhitungan menggunakan standar API 8.2. Pada penelitian ini, hasil perhitungan berdasarkan API 8.2 adalah pada Cargo E diperoleh batch size 14308 m3 dan volume sampling can 1,43 liter selanjutnya untuk Cargo B1 sebesar 15.898 m3 dan 1,64 liter dan B2 sebesar 14.944 m3 dan 1,55 liter. Secara keseluruhan, pengambilan sampel crude oil pada PT XYZ dengan automatic inline sampling lebih unggul dalam hal efisiensi, keamanan, akurasi, dan konsistensi data dibandingkan dengan pengambilan sampel secara manual.

Abstract

This study aims to analyze the working posture of operators using chairs and computers in the demineralization unit (demin plant) at PT. XYZ by applying the Rapid Office Strain Assessment (ROSA) method. Prolonged computer use with non-ergonomic postures can cause musculoskeletal disorders. The research method used direct observation of two operators with Nordic Body Map (NBM) questionnaires for initial complaint identification, followed by ROSA analysis. The results show that two operators scored 8 on the ROSA scale, which falls into the very high-risk category. This score indicates that the working posture is not ergonomically appropriate and has the potential to cause musculoskeletal disorders. Contributing factors include improper sitting posture not meeting ergonomic standards, absence of adjustable armrests, monitor position too low with viewing angles of 4.38° and 9.43°, monitor viewing distance of 40-45 cm (less than the 50-70 cm standard), and work equipment that does not fully support optimal comfort. Improvement recommendations include using ergonomic chairs with adjustable features, height-adjustable monitor stands, ergonomic workstations, and providing mousepads and portable keyboards. This study contributes to the application of office ergonomics to prevent musculoskeletal disorders in oil and gas industry workers.

Abstract

The quality of a product produced is a top priority for the company. The need for the use of chemicals for product quality in the company must also be taken into account so that it can be used efficiently, therefore in planning raw material requirements, a forecasting analysis of the needs of these secondary raw materials can be carried out. Based on the planning of the need for the use of these chemicals, the author conducted a study discussing the Forecasting of Aluminum Sulfate Al2(SO4)3 Needs in the company to improve production quality using the single moving average method. The study used qualitative and quantitative research methods, the study was aimed at seeing the application of the use of forecasting methods in companies and as a reference for learning the application of these methods for students. The author uses historical data on the use of Alum or Aluminum Sulfate in 2022 to May 2023 at one of the water treatment installations as a water purifier, with a movement value of n = 5,6,7,8,9. The results of the forecasting calculation obtained the lowest error rate in MSE and MAPE, namely at movement 5.
