Abstract

The background of this research is the demand for raw materials and the number of sales targets in UMKM Kerupuk Nasi Pak Tatang which have not been fulfilled and the level of product defects which is still high. The research purpose is to determine the performance measurement of supply chain management (SCM) and evaluate the performance measurement based on the lowest score. The method used is the Green SCOR method for determining performance measurements. Data in the form of filling out questionnaires by business owners, the amount of raw materials, the amount of production per month, and the number of defective products. The results showed that the final total value of the Green SCOR performance was 47,066 (marginal level category). Indicators that have a low score are source reliability (number of suppliers according to criteria), deliver responsiveness (length of time for ordering until goods arrive), deliver flexibility (time needed to place additional orders), and return responsiveness (number of complaints received by companies about products). The evaluation given for the number of suppliers is that the company must be able to evaluate each supplier by providing an assessment of the performance results with the AHP method. Evaluation of the length of time for orders to arrive and time for reorders to forecast raw material requirements to optimize order time. The final evaluation for the number of complaints is to provide complaint submission facilities that can be evaluated periodically using the PDCA approach (plan, do, check, action).

Abstract

Indonesia is a country located along the equator and has a tropical and subtropical climate. This condition supports the growth of various plant species with high diversity. Bintaro, or Cebera manghas, belongs to the Apocynaceae family and is believed to have potential as a vegetable insecticide. The purpose of this study was to determine the secondary metabolite compounds contained in methanol extract of bintaro plant stems and to determine the toxicity level of methanol extract of bintaro plant stems. This research method consists of 3 stages, namely extraction, phytochemical test (color test) and toxicity test. Extraction is done by maceration method using methanol solvent. Phytochemical test was done by color test. Toxicity test was conducted using BSLT method. The results of the toxicity test of methanol extracts of bintaro plant stems have an LC50 value of 100.697 and obtained the results of phytochemical tests of bintaro plant stems containing alkaloid and flavanoid compounds. Based on the LC50 value, it can be concluded that the methanol extract of bintaro plant stems falls into the medium category and contains alkaloid and flavanoid compounds.

Abstract

Chemistry laboratory experiments often use hazardous chemicals that can pose health risks and cause environmental damage. Green chemistry-based chemistry experiments are important because they use materials that are safe for students and the environment. Unlike previous laboratory manuals, this manual integrates green chemistry principles and digital features to enhance student independence. The purpose of this study was to examine the practicality and effectiveness of the green chemistry-based chemistry practicum guide on acid-base indicator material. This study was a Research and Development (R&D) study using the Borg and Gall model. This study focused only on the limited trial stage, initial product revision, and field trials to test the practicality and effectiveness of the Practicum Guide. Data collection techniques used questionnaires to determine practicality scores and N-Gain tests for effectiveness. The results of the practicality score analysis of the green chemistry-based chemistry practicum guide for teachers were in the very practical category, while students were in the practical category, reinforced by the results of observations of teacher and student activities in the very good category. The results of the analysis of the effectiveness of the green chemistry-based chemistry Practicum Guide using N-Gain were in the moderate category. Thus, this chemistry Practicum Guide is practical and effective for use in simple acid-base indicator practicums.
