Abstract

Scheduling is an important area of production planning and control. Scheduling is required to produce an existing job by allocating existing resources in the proper execution order. Production schedules arranged effectively and efficiently to maximize resources utility, minimize waiting and idle time and increase productivity. The flowshop batch scheduling model for one machine that takes inventory and quality cost into account has been developed by Indrapriyatna et al (2007a). However, the model yet effective in converting the results of batch size into integers. This study tried to resolve this problem by using a modification of Branch and Bound Algorithm approach.

Abstract

Inventory is one of many factors of the business operation that need to be controlled by industries in order to improve efficiency, enhance productivity, and decrease the holding cost. The holding cost of inventories in supply chain contribute to 20% - 40% of the product value. It can be controlled by applying appropriate inventory model, such as EPQ/Economic Production Quantity and EOQ/Economic Order Quantity. EPQ is an inventory model that used to determine the optimum production lot size with balanced the production setup cost and holding cost. Even the classic EPQ has applied widely in industries, the assumption used by this model differed between the researchers whether it is continuous or discrete demand, because the multi delivery or discrete demand is mostly used by industries. Even so, there are industries that used both continuous and discrete demand simultaneously. Based on previous research, there was an advanced EPQ model that synchronizing both assumptions simultaneously, but it still addressed single item problem. Since almost the industries produced multi item, this model has lack of applicability. Therefore, this research proposed a multi item EPQ Model that synchronizing continuous and discrete demand simultaneously. The solution procedure that used in this proposed model are classical calculus method/differential calculus and simultaneous approach. A numerical example is given to show the effectiveness of the proposed approach based on the data from the literature.

Abstract

Revolution of industry 4.0 initiated by the German government, starting from the development of individual innovation behavior especially in the fields of robotics, digital technology, and information, has caused distortions to the future skills requirements. Some of the skills needed a lot in the past are now starting to experience a shift towards less needed. Some are even unnecessary because they are replaced by automation and robots. The emergence of several new skills (skills 4.0) that are more dominant is needed to make every interested party to prepare themselves to face the challenges of the revolution of industry 4.0. Students are one of the interested parties who will face the challenges of the revolution of industry 4.0 after they graduates from the formal higher education. This study determines the readiness of students in facing the revolution of industry 4.0, influenced by the mastery of skills 4.0 and individual innovation behavior with their innovation behavior as a mediating variable. Respondents in this study are 233 undergraduate students of the Andalas University. Using a cluster sampling technique, the data is collected using Likert scale based- questionnaire after which calculations are then performed using the Smart-PLS Program software 3.2.8. The results show that skills 4.0 and individual innovation behavior have a positive effect on students' readiness in facing the challenges of the revolution of industry 4.0. It implies that the students need to improve their mastery of skills 4.0 in order to prepare themselves to face the challenges of the revolution of industry 4.0.

Abstract

Mortar is a cementation material composed of sand and cement with added water. River and mountain sand are types of sand that are available in large quantities in Bengkulu City. This study aimed to determine the effect of grain fine modulus from river sand on the compressive strength of mortar compared to Curup Mountain Sand. The sand river used was Kembang Sri River Sand (MHB 2,91), Penanding (MHB 2,204), Lubuk Kebur (MHB 3,452), Talang Rasau (MHB 2,257) and Curup Mountain Sand (MHB 1,29). The ratio variation between cement and sand used was 1Pc : 4Ps, 1Pc : 5Ps and 1Pc : 6Ps. Each variation was made 6 cube samples with a side dimension of 50 mm. The test was done at the age of the sample 28 days. The initial flow of the mixture plan is 105-115%. The results obtained of the highest value of mortar compressive strength for the mixture of 1Pc : 4Ps and 1Pc : 6Ps was found in Curup Mountain Sand, which was 14,08 MPa and 7,77 MPa. The highest value of mortar compressive strength for 1Pc : 5Ps mixture was found in Talang Rasau River Sand, which was 11.43 MPa (120,44% compared to Mountain Sand). The 1Pc:4Ps and 1Pc:6Ps mixture of Talang Rasau River Sand has a strength of 87.64% and 93.17% compared to Mountain Sand. Kembang Sri River sand has the lowest mortar compressive strength value for each mixture of 1Pc : 4Ps, 1Pc : 5Ps and 1Pc : 6Ps, compared to the strength of mountain sand was 34,80%, 27,40% and 28,57%. On the average, river sand with the gradation in zone III can be used for mortar mixture, although its strength is still below that of mountain sand. Keyword : river sand, mountain sand, mortar, fine modulus compressive strength.
