Abstract

This study evaluates the effectiveness of an ergonomically redesigned office chair, tailored to meet the anthropometric needs of employees. It addresses common issues associated with prolonged sitting, such as musculoskeletal discomfort and fatigue, which are prevalent in sedentary work environments. Utilizing anthropometric data from prior studies, the redesign incorporates modifications in key chair dimensions—such as seat height, seat depth, and backrest height—to enhance user comfort and reduce physical strain. The ROSA (Rapid Office Strain Assessment) tool was employed to assess posture and ergonomic risk for both the old and redesigned chairs. Findings indicate a significant improvement in ergonomic support and comfort with the new design, supported by a statistically significant reduction in ROSA scores, as confirmed through a paired sample t-test. Although the redesign effectively enhances comfort, further improvements are recommended, including adjustable lumbar support and backrest flexibility. This study underscores the importance of ergonomic adaptations in office furniture to support diverse body types and reduce occupational health risks.

Abstract

This study aims to analyze the application of hygienic design to utilize the excess supply of cayenne pepper during the peak harvest season, where many harvests are not absorbed into the market. Meanwhile, during the harvest in the off-season, the amount of chili harvest is unable to meet market demand, resulting in a spike in the price of cayenne pepper. The spike in the price of cayenne pepper has quite high variability, where the lowest price is IDR 15,000.00 but the highest price can reach IDR 100,000.00. With the implementation of the use of the DrySter Eco House drying house, farmers can store excess harvest results when prices drop and process them as dried cayenne pepper supplies and then sell them when the supply of fresh cayenne pepper on the market is low and the selling price is high. The DrySter Eco House greenhouse system relies on solar energy as the main source. This approach utilizes a greenhouse structure equipped with temperature and humidity control technology, as well as air circulation assistance that utilizes energy from solar panels to maintain optimal conditions during the drying process. By using greenhouse technology, the water content of cayenne pepper can be reduced significantly in a shorter time compared to conventional open drying methods. The use of renewable energy not only reduces operational costs, but also supports environmental sustainability and is able to maintain the quality of dried cayenne pepper. This study includes trials and measurements of several variables, such as temperature and drying time, to compare the results of conventional drying with drying using the DrySter Eco House prototype. With the supply of cayenne pepper from prospective harvest waste, farmers can stabilize the supply of chili during the off-season while also obtaining additional income from the sale of dried chili.

Abstract

Bahan baku menjadi komponen penting dalam proses produksi perusahaan manufaktur yang bergantung pada supplier. Oleh karena itu diperlukan hubungan yang baik dengan supplier melalui Supplier Relationship Management (SRM) yang meliputi evaluasi kinerja supplier. PT. XYZ mengalami beberapa kendala pengadaan bahan baku sehingga perlu menerapkan SRM. Proses evaluasi pemasok menggunakan metode Analytical Hierarchy Process (AHP) yang melibatkan pemberian bobot pada berbagai kriteria dan alternatif pemasok. Bobot akhir dari setiap pemasok kemudian dihitung untuk menentukan klasifikasi pemasok ke dalam tiga kategori: bad, good, dan excellent supplier. Dari evaluasi yang dilakukan kepada keempat supplier yang ada diperoleh 2 kategori kelompok supplier yaitu PT. A dan PT. B yang termasuk dalam kategori Excellent Supplier, kemudian PT. C dan PT. D yang termasuk dalam kategori Bad Supplier. Output dari evaluasi supplier digunakan untuk mengelompokkan supplier sesuai kinerjanya dengan menggunakan supplier relationship assessment. Hasil pengelompokkan supplier dari keempat supplier, terdapat 2 kelompok strategi yaitu prime group dan improvement group. Framework SRM dibuat untuk meningkatkan hubungan pemasok-perusahaan melalui evaluasi dan seleksi pemasok.

Abstract

PT Pamapersada Nusantara KPCS menghadapi kendala dalam pencapaian target On Time In Full (OTIF) untuk distribusi sparepart lokal unit remanufacturing. Ketidaktercapaian ini berdampak pada efisiensi rantai pasok dan layanan terhadap user internal (departemen remanufacturing).Hasil yang diperoleh menunjukkan bahwa dengan adanya penurunan hampir 78%/110 range A item stock yang dipilih dari total stock awal ABC (496 item), maka berdampak pada penurunan efektifitas, efisiensi proses pengadaan, penghematan waktu. Berdasarkan perhitungan penentuan nilai ROP-ROQ, persediaan dapat dikatakan efektif karena hasil output status pergerakan tidak ada yang berstatus dalam kategori “Slow Moving” maupun “Dead Stock” dan dari segi prediksi lead time kategori pergerakan, nilai maksimal dalam waktu 3 bulan masih dikatakan efektif untuk dapat dimanfaatkan oleh user. Pemilihan metode VHS dan Centralized Local Stock merupakan metode kombinasi persediaan strategis yang berdampak pada proporsi distribusi yang seimbang terkait okupansi own stock dan VHS stock. Pada akhir proyek, nilai readiness tercapai di atas target KPI yaitu 99% dan kinerja OTIF tercapai di atas target KPI yaitu 90% dari tahap antar proyek hingga akhir proyek.Kata kunci: OTIF, Readyness Stock, ROP, ROQ, ABC, Moving Status
