Abstract

This study aimed to determine the optimum concentration of the use of chitosan in dried anchovies to produce maximum preserved dried anchovies. The anchovies used were 300 grams of wet anchovies in each treatment sampel. The sampel is divided into thee parts, namely sampel 1 with the addition of chitosan each of 1%, 2% and 3%. The results showed that the water content were 33,6%, 33,4% and 32,8% respectively.  While the microbiological test showed that the use of chitosan 3% in dried anchovies has a TPC (Total Plate Count) value has an average value lower than dried anchovies with the use of chitosan as much as 1% and 2%. The preferred organoleptic test is dried anchovies which uses chitosan as much as 3% in the parameter of color, visual, aroma and taste. The Results of the study concluded that the most optimal use of chitosan as preservative in the production of dried anchovies was 3%.

Abstract

This research is propose the replacement schedule of a critical part of a critical machine in a the clove line of PT. Hanjaya Mandala Sampoerna Tbk. From the direct observation, the screw conditioning process is the critical process of the the tobacco production in clove line. One of the screw conditioner, Garbuio Dickinson screw conditioner, was observed as the machine with the most downtime in clove line. Further analysis using chart reveals that the motor screw conditioner is the main problem to the machine breakdown. Index of fit calculations were applied to find the time to failure and time to repair distribution by looking at the highest index of fit of each failure distribution. Maximum Likelihood Estimator step was undergone to find the MTTF and MTTR (in hours) for the chosen distribution. Finally, the best time interval to replace the critical part in order to increase the component reliability and machine availability was calculated. Result of this preventive replacement is increases the component reliability by 80% and the machine availability by 0.245%.

Abstract

Fish is one of the species that is in high demand by consumers, including in Aceh. Fish can be obtained by catching from abundant nature. Problems in processing fish catches in Aceh, especially Langkak Village, Kuala Pesisir District, Nagan Raya Regency is a conventional post-capture processing method, which is drying using the heat of sunlight. In this condition, fish drying has several disadvantages, which are related to dependence on sunlight heat, cleanliness, freshness of fish, and selling points. For this reason, there needs to be a way to implement simple technology that uses a fish fogging machine. The purpose of carrying out this community service program is to provide practical applications of the fish fogging technique by providing soft skills to members of the fishing group in the Village of Langkak Village, Kuala Pesisir District, Nagan Raya Regency. The results of community service activities have been going well, starting with socialization activities or theory to the practice or application of fish fogging. The achievement of community service activities is the transfer of knowledge about making fish fogging machines and the practice and application of fish fogging directly by the fishermen of Langkak Village. In addition, other results are a manual guide on fish fogging to get the optimal fish fogging results. This activity received a good response from the fishermen of Langkak Village who participated in the activity, because it was considered very useful and became a facility to empower fishermen and residents in general.

Abstract

result of viability of papaya seed (carica papaya L.) The experimental design used in this study is a complete randomized design (RAL) 4 x 2 factorial pattern with 3 replications consisting of two factors, with There were 8 treatment combinations and 24 experimental units. The materials used in this research are papaya seed, cotton cloth, ash, concentrated H2SO4, and sand. The parameters observed were potential to grow, germination, growth rate and time required 50% from total germination (T50). The results of this study indicate that the average value of viability and vigor is high in the show on the optimization of the way of extraction of cotton cloth (K1). Viability and vigor of sprouts which are better found in local varieties (V1) than with hybrid varieties (V2). Better interaction optimizing the way extraction of sarcotae is found in hybrid varieties (V2) seeds by extraction of cotton cloth (K1). So it can be concluded that the optimization of sarkotesta extraction method is very significant effect on seed viability include growth potential, germination, growth rate and T50% sprout total.Keywords: Sarkotesta extraction, viability, papaya seed (Carica papaya L.).

Abstract

Purchasing raw materials aims to obtain an item that is needed by the company so that we carry out transactions to get the goods needed to achieve a smooth production process at the company. In purchasing raw materials, companies usually have a capacity in purchasing to save costs in order to provide benefits for the company. PT Wirataco Mitra Mulia is a company that processes in the field of stockpiling and asphalting of the Trumon Singkil boundary road. The results of research at PT Wirataco Mitra Mulia use of raw materials every day as much as 300m3/day, while it the purchasing section the average is 600m3/day. As a result of purchasing too many raw materials, it causes purchasing costs to increase in the company and experience wasted costs in purchasing raw materials. The purpose of this study is to analyze the purcashe of raw materials that are the most economical, efficient, and at a lower cost by using the Ecenomic Order Quantity (EOQ) method. From the results of the calculation of the Ecenomic Order Quantity (EOQ) method, the total cost of purchasing raw materials (sirtu) is Rp 131.400.000, 657 treps, safety stock is 5400m3, reorder point is 27.200m3.
