Abstract

Green Supply Chain Management didefenisikan sebagai aktifitas manufaktur yang ramah lingkungan (Green Manufacturing), kegiatan pendistribusian yang juga ramah lingkungan (Green Distribution) serta reserve logistic. UKM Kain Jumputan merupakan salah satu UKM yang ada di Kota Palembang. Penelitian ini mengenai penilaian kinerja Green Supply Chain Management di UKM Kain Jumputan agar UKM ini dapat terus mengembangkan usahanya dengan baik serta memberikan rekomendasi perbaikan berdasarkan hasil pengukuran kinerja yang telah dilakukan. Penelitian ini menggunakan metode Green SCOR Untuk mengukur kinerja Green Supply Chain Management kemudian didukung dengan metode pembobotan AHP. Dari hasil perhitungan diperoleh nilai kinerja sebesar 79,4. Hal ini berarti UKM tersebut dalam kategori Good. Namun terdapat 6 KPI dari 24 KPI yang membutuhkan perbaikan. Perbaikan yang disarankan pada UKM diantaranya Percentage supplier with an EMS, Recycleable waste, Sewege treatment plant cost, Defective product recycleable, Percentage of solid waste recycling, Percentage of waterwaste recycling Green Supply Chain Management is defined as environmentally friendly manufacturing activities (Green Manufacturing), distribution activities that are also environmentally friendly (Green Distribution) and reserve logistics. JUmputan Cloth UKM is one of the UKM in Palembang City. This research is about evaluating the performance of Green Supply Chain Management in the Jumputan Fabric UKM so that these UKM can continue to develop their business well and provide recommendations for improvements based on the results of performance measurements that have been carried out. This study uses the Green SCOR method to measure the performance of Green Supply Chain Management and is supported by the AHP weighting method. From the calculation results obtained a performance value of 79.4. This means that the UKM is in the Good category. However, there are 6 out of 24 KPIs that need improvement. Suggested improvements for SMEs include Percentage supplier with an EMS, Recycleable waste, Sewege treatment plant costs, Recycleable Defective products, Percentage of solid waste recycling, Percentage of waterwaste recycling

Abstract

The amount of used cooking oil is increasing along with human activities. Used cooking oil that is disposed directly into the environment will give a negative impact on health and the quality of the environment, therefore it is necessary to purify the used cooking oil so that the used cooking oil can be reused. In this study, used cooking oil that has been used with heating time of 3 hrs, 5 hrs, and 7 hrs was used. The used cooking oil was purified using activated carbon made from 100 mesh bagasse with variations in weight of 2.5 g, 5 g, and 7 g, soaking time of activated carbon in used cooking oil were 24 hrs, 48 ​​hrs, and 72 hrs. The analysis used is the analysis of water content, free fatty acid content, and the amount of saponification. The results showed that the water content and saponification rate decreased with the length of contact time and the weight of activated carbon. The lowest free fatty acid content was produced when using activated carbon 7.5 g and contact time for 24 hrs.

Abstract

Eggshell is a part that protects egg components from various external threats, including chemical, physical, and biological factors. This study aimed to obtain an adsorbent from chicken eggshells using physical and chemical activation techniques. The quality of the eggshell-derived adsorbent was assessed and compared with the Indonesian National Standard (SNI) 1995, with a focus on parameters such as ash content, moisture content, and iodine absorption. The adsorbent obtained was applied to a solution of methyl orange, and Fourier transform infrared spectroscopy (FTIR) analysis was conducted before and after the adsorption process. Furthermore, the study stages include adsorbent preparation, activation, and adsorption. The adsorbent weight for this process was 17 grams, with time intervals of 15, 30, 45, 60, and 75 minutes. The results showed that both physically activated as well as physical and chemical activated adsorbents met the SNI 1995 standard, based on the parameters of water content (1.73% and 2.86%), ash content (8.18% and 6.745), and iodine absorption (761.40 mg/g and 774.09 mg/g). FTIR analysis confirmed the presence of a hydrocarbon and an OH group in the structure before and after adsorption. The optimum methyl orange adsorption capacity was achieved at an adsorbent mass of 17 grams and a contact time of 60 minutes, resulting in removal efficiencies of 20.38% for physical activation and 24.11% for physical and chemical activation.
