Abstract

The rapid development of digital broadcasting technology and the implementation of the Analog Switch-Off (ASO) policy have intensified competition among television brands and increased the occurrence of brand switching behavior among consumers. This condition requires business owners to understand consumer switching patterns in order to anticipate market share changes and develop more effective marketing strategies. This study aims to analyze consumer switching patterns among television brands, predict future market share, and determine the long-term equilibrium condition (steady state) using the Markov Chain method. The research was conducted at UMKM XYZ using a quantitative approach with data collected from questionnaires distributed to 50 respondents over a 90-day observation period. The analysis involved constructing a transition probability matrix, determining the initial market share vector, forecasting market share across several periods, and identifying the steady-state condition. The results indicate that the initial market shares were 18% for Aqua, 32% for LG, 24% for Polytron, and 26% for Sharp. The forecast shows that Polytron experienced the highest market share growth and became the dominant brand, while LG experienced a significant decline. The steady-state condition was reached in the fifth period, with long-term market shares of 24% for Aqua, 17% for LG, 37% for Polytron, and 23% for Sharp. These findings demonstrate that the Markov Chain method is effective for predicting brand switching behavior and market share distribution, providing valuable support for marketing decisions and inventory management in UMKM XYZ.

Abstract

Penelitian ini bertujuan menganalisis dan mengevaluasi sistem antrean pelayanan farmasi pada Puskesmas Bojonegoro menggunakan pendekatan simulasi Monte Carlo dan discrete event simulation berbasis Arena. Permasalahan utama berupa ketidakseimbangan antara laju kedatangan pasien dan kapasitas pelayanan yang menyebabkan antrean serta peningkatan waktu tunggu pasien. Data penelitian diperoleh melalui observasi langsung terhadap waktu kedatangan pasien, waktu pelayanan, jumlah resep, dan kapasitas tenaga farmasi. Analisis dilakukan menggunakan model antrean M/M/2 dengan indikator kinerja berupa waktu tunggu rata-rata, panjang antrean, dan utilisasi petugas. Hasil penelitian menunjukkan bahwa rata-rata waktu tunggu aktual sebesar 2,64 menit dengan utilisasi sistem sebesar 33%. Simulasi skenario penambahan satu petugas pelayanan mampu menurunkan waktu tunggu menjadi 1,59 menit. Hasil simulasi menunjukkan bahwa metode Monte Carlo dan Arena efektif digunakan sebagai dasar pengambilan keputusan dalam meningkatkan efisiensi pelayanan farmasi.

Abstract

Perawatan mesin memiliki peranan penting dalam menjaga keandalan dan efisiensi operasional industri. Penelitian ini bertujuan untuk menganalisis penerapan metode Total Productive Maintenance (TPM) dalam kegiatan perawatan mesin Caterpillar 3508 DITA yang digunakan di PT. Tiga Musim Mas Jaya serta mengevaluasi efektivitasnya terhadap peningkatan kinerja mesin. Metode penelitian yang digunakan adalah observasi lapangan, wawancara, serta analisis data perawatan mesin yang kemudian diolah menggunakan pendekatan Overall Equipment Effectiveness (OEE) sebagai indikator kinerja. Hasil analisis menunjukkan bahwa penerapan TPM mampu meningkatkan keandalan mesin dengan menurunkan downtime serta meningkatkan nilai availability, performance, dan quality. Nilai OEE yang diperoleh menunjukkan bahwa kinerja mesin berada pada kategori baik dan mendekati standar yang ditetapkan, meskipun masih terdapat potensi peningkatan melalui pengawasan dan inspeksi berkala yang lebih optimal. Dengan demikian, penerapan TPM terbukti efektif dalam mendukung peningkatan kinerja dan efisiensi operasional mesin Caterpillar 3508 DITA serta dapat dijadikan sebagai acuan dalam pengelolaan sistem perawatan mesin di lingkungan industri.

Abstract

Inkatama Wancheng Indonesia merupakan perusahaan manufaktur yang memproduksi komponen plastik dengan mengandalkan mesin moulding sebagai sarana produksi utama. Efisiensi operasional pada lini produksi sangat bergantung pada keseimbangan beban kerja yang diterima oleh operator. Penelitian ini bertujuan untuk menganalisis beban kerja fisik operator mesin moulding dan menentukan jumlah tenaga kerja yang optimal guna menghindari kondisi beban kerja berlebih (overload) atau kurang (underload). Metode yang digunakan adalah Workload Analysis (WLA) dengan pendekatan indeks Full Time Equivalent (FTE). Data dikumpulkan melalui observasi langsung terhadap aktivitas produktif dan nonproduktif, serta pengukuran waktu siklus kerja menggunakan stopwatch. Hasil penelitian menunjukan bahwa rata-rata waktu kerja efektif operator adalah 420 menit perhari dengan mempertimbangkan faktor kelonggaran (allowance). Berdasarkan perhitungan, diperoleh nilai indeks FTE rata-rata operator mesin moulding berkisar antara 1,05 hingga 1,20. Hasil ini menunjukan bahwa beban kerja operator saat ini berada dalam kategori optimal (in-load). Meskipun demikian, fluktuasi beban kerja tetap terjadi akibat adanya waktu tunggu (waiting time) dan kendala teknis mesin secara mendadak. Perusahaan disarankan untuk melakukan monitoring berkala dan optimalisasi waktu tunggu mesin guna menjaga stabilitas produktivitas kerja.

Abstract

This research aims to analyze the implementation of Total Productive Maintenance (TPM) method on Caterpillar 3406 machine at PT. Tiga Musim Mas Jaya to improve the effectiveness and reliability of production machines. The research methods used include field observation, interviews, and analysis of machine operational data such as operation time, downtime, production quantity, and product quality. Machine effectiveness is measured using Overall Equipment Effectiveness (OEE indicator which consists of availability, performance, and quality. The results showed availability value of 96.15%, performance of 95.00%, and quality of 98.58%, thus obtained OEE value of 90.04% which is categorized as very good according to Japan Institute of Plant Maintenance standard (?85%). The implementation of TPM is proven to reduce downtime, increase machine reliability, and support the achievement of production targets. Therefore, TPM is recommended as a sustainable maintenance strategy to improve company productivity.

Abstract

This study was conducted at PT. Tiga Musim Mas Jaya, an oil and gas drilling service company, aiming to evaluate the implementation of Periodic Inspection (PI) in the preventive maintenance system of Unit C15. Data were collected through field observations, interviews with field supervisors, and analysis of scheduled and unscheduled breakdown records over a six-month observation period. The results show that the implementation of Periodic Inspection significantly improved maintenance performance, with a Physical Availability value of 98.75%, Mean Time Between Failure (MTBF) of 144 hours, and Mean Time To Repair (MTTR) of 1.07 hours. In addition, PI Achievement and PI Accuracy both reached 100%, indicating consistent and timely inspection execution. These findings demonstrate that Periodic Inspection as part of preventive maintenance effectively enhances equipment reliability, operational readiness, and maintenance efficiency in the oil and gas sector
