Abstract

As an agricultural country, agriculture in Indonesia is one of the most important economic sectors in the national economy, one of which is clove farming. The research was conducted in a clove tree plantation located in the Purwakarta area. Data collection was carried out by interviews and giving the Nordic Body Map questionnaire to clove farmers. This data collection was aimed at 5 respondents with the aim of finding out complaints and several suggestions from clove farmers. The results of the Nordic Body Map Questionnaire data, the highest rank results were obtained, namely pain in the soles of the left foot and right foot with 3 people answering very painful and 2 people answering painful, to the lowest namely pain in the back, upper waist and lower waist with a total of 4 people answered sick and 1 person answered a bit sick. After obtaining physical complaints with the Nordic Body Map, then carry out REBA analysis to determine the REBA score when farmers climb clove trees and harvest clove flowers. After obtaining the REBA score, the score obtained from climbing clove trees was 8, which means it has a high level of risk and requires investigation and implementation changes to reduce the risk of physical complaints in farmers, while the score from harvesting clove flowers is 12, which means it has a very high level of risk. high and implementation changes are needed to reduce the risk of physical complaints among farmers. For product dimensions, the product dimensions are obtained, namely that the clove tree climbing ladder product has a height of 500 cm. The distance per step is 35 cm. The length of the stair step is 50 cm.

Abstract

Dalam era industri saat ini, keberlanjutan menjadi aspek krusial dalam mengelola operasional perusahaan. Fokus penelitian ini adalah pada rantai pasok produk medis habis pakai yang didistribusikan oleh sebuah perusahaan distributor peralatan kesehatan. Produk medis habis pakai memiliki siklus pemakaian singkat, berpotensi memberikan dampak signifikan terhadap lingkungan. Produk ini sering menghadapi masalah seperti penuaan inventaris, yang meningkatkan risiko produk kedaluwarsa karena kurangnya penjualan, dan akhirnya dapat berujung pada penumpukan limbah. Selain itu, peningkatan emisi CO2 yang disebabkan oleh transportasi yang tidak ramah lingkungan memberikan dampak negatif tambahan pada lingkungan. Solusi untuk mengatasi permasalahan ini melibatkan implementasi pengukuran kinerja rantai pasok hijau. Penelitian ini bertujuan memberikan rekomendasi perbaikan pada setiap tahap rantai pasok menggunakan metode Green SCOR (Green Supply Chain Operation Reference) untuk mendekomposisi proses, dan AHP (Analytical Hierarchy Process) untuk memberikan bobot pada hierarki KPI. Hasil penilaian dengan Objective Matrix dan Traffic Light System menunjukkan bahwa hasil dari pengukuran kinerja GSCM secara keseluruhan adalah 5,482 yang berarti performa perusahaan dikatakan cukup dan membutuhkan perbaikan untuk mencapai target maksimum. Terdapat 10 indikator kinerja yang sudah baik, 4 indikator kinerja yang belum maksimal dan 4 indikator kinerja yang memerlukan perbaikan guna meningkatkan kinerja perusahaan. Perbaikan ini menjadi krusial untuk memastikan keselarasan rantai pasok dengan prinsip-prinsip lingkungan dan berkontribusi pada keberlanjutan usaha.

Abstract

Hospitals are health facilities that provide medical services and care for patients. Every hospital is always required to maintain and quality of service in order to achieve customer satisfaction and improve efficiency. Lean Management can be used as an approach to improve service quality and efficiency. The first step of improvement is to identify waste in the hospital. This article aims to discuss identification of waste in the outpatient unit of a hospital. Furthermore, determine the priority of waste that must be reduced (eliminated). The methods used are observation, interview and fuzzy. The results showed that the waste that is prioritized to be reduced (eliminated) are patients waiting for the next process (W2), the process of supplying repetitive drugs (OVP2), and patients waiting for registration (W1). The results of this study can be used by hospital management as a reference for making improvements, both in the outpatient unit and other service units.
