Analisis Komparatif Teknik Peramalan Double Exponential Smoothing, Moving Average, dan Linear Regression Pada Permintaan Item Outer Generic Uli
No full textPT EPK is a company engaged in the printing and packaging industry, producing cardboard, paper pallets, and polyfoam. One of its products, Outer Generic Uli, experiences unstable demand, making it difficult for the company to accurately forecast market needs. Inaccurate forecasting can lead to stock overages or shortages and increased storage costs. Moreover, selecting the most appropriate forecasting method remains a challenge. This study aims to compare three forecasting methods—moving average, double exponential smoothing, and linear regression—to determine the most accurate model. Forecast accuracy is evaluated using tracking signal and mean square error (MSE). The results show that linear regression yields the most accurate forecast with the lowest MSE of 642,460.32. In comparison, double exponential smoothing has an MSE of 991,250, while moving average results in an MSE of 2,832,031.25. The significant difference in MSE indicates that linear regression outperforms the other methods. Implementing this method is expected to optimize inventory management, reduce the risk of stock imbalance, and enhance both supply chain efficiency and decision-making accuracy..

Penerapan Ergonomi pada Penjual Jamu Gendong dengan Metode RULA dan REBA di Kaliawi Persada
No full textA risk of musculoskeletal disorders (MSDs) due to non-ergonomic work postures was found in herbal medicine sellers. This study aims to analyze the posture and ergonomic risk levels using RULA, REBA, and Nordic Body Map (NBM) through observation and interviews with three respondents (aged 21, 33, and 63 years) who work an average of 2–3 hours per day with a load of 7 kg. The results of the study using Rula and Reba showed that the work posture was not fully ergonomic, with Rula values of 4 and Reba values of 9. RULA and REBA values indicate a moderate to high risk level, especially in elderly respondents. Although there have been no significant musculoskeletal complaints, the potential for musculoskeletal disorders can increase if work habits are not immediately corrected. It is necessary to apply ergonomic principles such as using a more ergonomic carrier (wide and soft straps), adjusting the load balance, taking active breaks and stretching, using alternative pushing aids (trolleys) on flat areas. Overall, the workload is still considered safe according to metabolic energy, but body efficiency decreases with age.

No full textPerjanjian kerja merupakan bagian penting dari hubungan industrial antara pekerja dan pemberi kerja (pengusaha). Oleh karena itu perjanjian kerja dalam hubungan industrial diatur dalam berbagai undang-undang, dimaksudkan sebagai upaya memberi perlindungan secara adil dan seimbang atas hak-hak pekerja maupun pengusaha, agar tidak terjadi konflik berkepanjangan. Namun secara faktual perjanjian tidak selalu dipatuhi oleh para pihak yang mengadakan perjanjian. Penelitian ini berusaha mengungkap berbagai implikasi perjanjian kerja antara pekerja dengan pemilik usaha. Penelitian dilakukan di lembaga bisnis Senyum BRILink sebuah usaha Payment Points Online Bank (PPOB) yang berlokasi di Bandar Lampung. Penelitian difokuskan pada tiga hal, yaitu factor penyebab terjadinya wanprestasi, pola penyelesaian wanprestasi, dan efektivitas pola yang dipilih untuk menyelesaikan wanprestasi. Penelitian didesain sebagai jenis penelitian kualitatif dengan pendekatan yuridis empiris. Pengambilan data dilakukan menggunakan metode survey dengan memanfaatkan teknik observasi, wawancara, dan studi literatur. Analisis dilakukan secara deskriptif kualitatif. Hasil penelitian menemukan fakta bahwa telah terjadi tiga kali wanprestasi pada unit usaha Senyum BRILink, yaitu berhenti sebelum berakhir masa kontrak, penyelewengan dana, dan pelanggaran SOP. Dua kasus pertama dilakukan dengan sengaja, sedangkan kasus pelanggaran SOP disebabkan factor kelalaian. Ketiga kasus wanprestasi diselesaikan pemilik melalui pola alternatif penyelesaian sengketa (APS) dengan menempuh musyawarah bibartit. Penyelesaian APS ternyata cukup efektif, semua pihak dapat menerima penyelesian tersebut dan penyelesaian ini memberi dampak peningkatan kedisiplinan karwayan.
