QUALITY CONTROL IN SUGAR AGROINDUSTRY USING FAILURE MODE AND EFFECT ANALYSIS (FMEA) METHOD IN BONDOWOSO REGENCY

Nidya Shara Mahardika — 2023-12-18

The sugar agroindustry in Bondowoso, particularly PG Pradjekan, is a part of the business unit of PTPN XI that focuses on sugarcane processing. Its main product is white crystalline sugar, which must adhere to the Indonesian National Standard (SNI), with quality characteristics measured through sugar solution color (ICUMSA) and Grain Size (BJB). The quality of the produced white crystalline sugar is maintained through a monitoring process to ensure compliance with government-established standards.Quality monitoring involves control over ICUMSA and BJB, with the understanding that a smaller BJB results in a whiter ICUMSA, indicating better quality. The efforts in quality control aim to assist the company in maintaining and enhancing product quality in accordance with government standards. The company's target is to achieve zero defects, with a tolerance of 0.5%.Data from the milling process in 2022 at PG Pradjekan recorded sugar production of 16,693 tons. However, there was a defect rate of 0.92% of the total production, equivalent to 155 tons. These defects incur losses for the company as rejected products undergo reprocessing, leading to increased costs and prolonged production time. Therefore, improving quality control is crucial to reducing defect rates and enhancing overall production efficiency.

Essa Tri Handayani — 2023-12-18

Red chili (Capsicum annum L.) is one type of horticultural commodity with a high level of consumption and production. Jember Regency is one of the regencies in East Java Province where the cultivation of large red chilies is quite high. The results of preliminary observations in the field indicate that several problems have occurred, such as an imbalance in the distribution of risk among supply chain actors. Farmers as the main actors in the supply chain have the highest risk of crop failure due to seasonal uncertainty. Supply chain analysis and evaluation will provide information about the problems contained in the supply chain, which will then identify the risks causing the supply chain to be less than optimal and determine the direction of continuous, effective, and efficient improvement in the supply chain of large red chilies. This study aims to minimize or eliminate the impact of risks that occur during large red chili supply chain activities in the Ambulu District. This research was conducted by applying the SCOR model for supply chain activity mapping and the House Of Risk (HOR) model for supply chain risk management. The identification results show that large red chili supply chain activities in Ambulu District have four activity patterns, then there are 28 risk events and 24 risk agents that occur in large red chili supply chain activities. Based on the calculation results, the results are in the form of seven risk management strategies in the large red chili supply chain which consist of conducting routine evaluations, choosing the right pesticides, collaborating with the local government, conducting routine treatment on plants, training workers, farming management, and counseling on the selection of the right seeds to farmers.

Dian Purbasari — 2023-12-18

Lemongrass (Cymbopogon citratus L.) can be known as an herbal plant that has many benefits. In addition, lemongrass can also be used to give a distinctive taste to a dish. The use of lemongrass in food can be done directly in a fresh form in the dish. The use of lemongrass in fresh form can be said to be less practical and cannot be stored for quite a long time. One of the things that can be done to extend the shelf life of lemongrass is to process fresh lemongrass into lemongrass powder. Therefore, one of the right handling to obtain good quality products and reduce lemongrass spoilage is by carrying out the drying process using a microwave. The purpose of this study was to determine the physical quality of lemongrass powder from microwave drying and study the relationship between microwave power and different bending durations to the physical quality of lemongrass powder. The results showed that the moisture content of fresh lemongrass ranged from 85,928 – 87.208% while the water content of lemongrass powder ranged from 5,876 – 9.728%. Lemongrass that has gone through the drying and scavenging process is then carried out the sifting process using a 60 mesh sieve. The lemongrass powder that passes the sieve is then measured for physical quality. The physical quality of the lemongrass powder produced is the physical quality of the lemongrass powder produced, which has a brightness level (L) ranging from 78.48-90.87; the degree of redness (a) ranges from -0.49 to - 1.45; yellowish level (b) ranges from 0.22 – 3.62; bulk density ranges from 0.41 – 0.48 g/cm3; water activity ranges from 0.33-0.40. Based on the results of statistical analysis, the physical quality of lemongrass powder with the best combination of treatments was obtained at microwave power difference treatment.

Hifdzil Adila — 2023-12-18

Peanuts are a horticultural product that has high nutritional content, but peanuts are semi-perishable so they have a short shelf life. The high water content of peanuts can be reduced by drying. The drying method using a horizontal rack type drying machine is able to optimize the drying process, especially for seeds, because it can be done at the desired time so that peanuts can have a longer shelf life. The aim of this research was to determine the effect of a horizontal rack type drying machine on the drying characteristics of peanut seeds in the form of water content, drying rate and differences in temperature, humidity and length of drying time. The research method used was using a rack type drying machine utilizing the working principle of the MSSD (Multi Seed Smart Drayer) machine and initial water content measurements were carried out using the gravimetric method. The data on changes in seed mass were then analyzed to obtain data on the decrease in water content and drying rate. Temperature and humidity data are obtained from data loggers. Based on the analysis that has been carried out, the values for drying characteristics of peanut seeds as well as changes in temperature and humidity show different values for each shelf. After drying for 6 hours, the initial water content of peanut seeds which was 23.80% was reduced to 17.20%.
