Abstract

The brick making process has two very critical characteristics / Critical To Quality (CTQ) , namely compressive strength and water absorption. For the quality characteristics of the compressive strength the greater the value, the better (Higher The Better). As for the absorption of water the quality characteristics are getting smaller, the better (Smaller The Better). The quality of the brick used as building material must have good quality that can maintain the strength of existing buildings. The quality in question is the compressive strength and absorbency of water produced must be in accordance with the requirements of SNI (Indonesian National Standard). The WS companies produce concrete blocks which have not good quality. The bricks are brittle. The method used in this study is the Taguchi method. Optimal Level Factor setting is Factor A (duration of stirring), Factor B (Pressure), Factor C (Water), Factor D (Drying) and Factor E (Composition of Sand and Lime). Where the optimal factor setting level factor that is most influential and dominant in compressive strength and water absorption is factor E (composition of sand and lime). For compressive strength factor E (sand and lime composition) level 2, 1: 0.25 and for absorption factor E (composition of sand and lime) level 1, 1: 0.5. and to confirm the results of this experimental design study, a percentage of Quality Loss Function of compressive strength and water absorption was obtained after the optimal level setting had a quality increase of 51.91% and a decrease in the Loss function of 78.5%.

Abstract

PT. Anugrah Ditamas Lestari is an agent of 3 kg LPG Gas, to distribute to bases. PT. Anugrah Ditamas Lestari has a problem in distributing 3 kg of gas to the base, so it must have good planning so that the items to be distributed can reach the base in a timely manner. Traveling Salesman Problem (TSP) is a distribution problem in the form of transportation equipment (vehicle) from the agent to the base then back to PT. Anugrah Ditamas Lestari (agent). The research conducted aims to determine the minimum mileage for each route. The preparation of this Gas distribution route was completed using the Heuristic Algorithm. The initial stage is the formation of a sub route which is the process of grouping the base into the route. The next stage of the sub route development phase that has been formed is based on the existing travel time, the last stage minimizes the distance where the agent must first deliver the product until the last base and return to the agent. Sub route formation is still done manually while to compare the final results is done using WinQSB Software. Based on this distance determination study, the distance traveled was closer, and did not come to the base twice.

Abstract

Abstract— The supply chain management of the coconut industry in the Sula Islands district is still felt to be ineffective and inefficient. The advantage of effective supply chain management is to get maximum speed when goods and services move through the supply chain channel, lower costs, and increase added value for customers and product competitiveness in the market. The purpose of this study is to identify and analyze the management of the coconut industry supply chain. The method used is descriptive qualitative analysis. Those who play a role in the coconut supply chain in the Sula Islands district are farmers, collectors I, collectors II, owners of home industries, transport vehicle owners and marine vessels as modes of transportation. With this supply chain channel, there are only a few benefits for farmers and business operators. The added value of coconut and copra is very small, meaning that the economic value obtained is very small. To provide greater economic value for residents of the Sula Islands district, especially for coconut farmers and coconut entrepreneurs, so coconut fruit must be processed not only until copra, but made in industrial scale coconut oil.Keywords— Supply Chain; Coconut; Industry; Coconut oil; Sula Islands Regency. Abstrak— Manajemen rantai pasok industri kelapa di kabupaten Kepulauan Sula masih dirasakan belum efektif dan efisien.

Abstract

Fluctuating and uncertain demand is a problem faced by manufacturing firms. The problem can be mitigated by the availability of inventory systems. This inventory serves to ensure the availability of appropriate resources in the right quantity and at the right time, so as to minimize the costs incurred. PT. Transplants Indonesia is a company engaged in the business of chrysanthemum flower in Indonesia. PT. Transplants Indonesia is a subsidiary of Okinawa Flower Agricultural Cooperative Association (OKF) in Okinawa, Japan. The purpose of this company establishment is to meet the demand of farmers who are members of the OKF. In the case of backorder, on Q method with probabilistic request the size of the lottery (Q) is always fixed for every time the order is made and the order is made if the amount of inventory system has reached a certain level (r) called the reorder point. In method P with probabilistic order requests made according to a fixed interval of time (T) and the ordering does not exceed the maximum inventory limit (R). Total Inventory cost incurred by the company using the method used by the company amounted to Rp.74.995.360,84. The inventory model using the Q method generates a total inventory cost of Rp.70.253.291,46. Meanwhile, inventory model using P method resulted in total inventory cost of Rp.71.529.327,17. So economically, the selected inventory model is the inventory model with the Q method which has a lower total inventory cost value than using the P method. Keywords— Inventory system, Probabilistic, Backorder, Method Q, Method P, Reorder point.
