Preventive maintenance is considered as a method to avoid unexpected failure in production machines. Unfortunately, conducting such maintenance is limited by resources availability thus likely causes tardiness. This research aims to minimize total tardiness of preventive maintenance on production machines by developing a scheduling model. This scheduling model takes the availability of time and labor into account to get an optimal scheduling model that can minimize the tardiness. The model of preventive maintenance schedule is developed by using the Integer Linear Programming method. This method provides output in the form of preventive maintenance schedule through a purpose function which considers the specified constraints on the company. As the result, the developed model could propose a preventive maintenance schedule which reduces the total tardiness.

Organization goals could be achieved by translating vision and mission into strategy. The strategy should be carefully formulated to direct the operation plans to work in harmony to achieve the goal. This research aims to show how the strategy is formulated based on the performance measurement result. The performance indicators are generated using the Balanced Scorecard approach with its four perspectives; financial, customer, internal business process, and learning and growth. Once these indicators and their benchmarks are defined, performance measurement is carried out. The performance measurement result is then input into a Strength-Weakness-Opportunity-Threat (SWOT) matrix. This approach proved that it could help the company review its existing strategy achievements and competitive position. Furthermore, the SWOT analysis proposes some potential actions taken by the company, which fall on Offensive, Defensive, Adjust, and Survive strategies.

Cement is a construction material with a specific quality that must be meet standard requirements and customer requirements. Through a good and continuous quality control, it will produce cement with consistent quality as its Quality Planning. Cement quality is calculated after adding water by measuring its setting time, compressive strength developing, the heat of hydration, expansion/shrinkage, and its durability to environment effect. In cement application, the primary parameter to determine cement quality is its compressive strength. Some factors that affect compressive strength of cement are reactivity and amount of Tricalcium Silicate (C3S) of Clinker, Clinker free lime (free CaO), amount of SO3 in Cement, the amount of additional materials (insoluble residue/IR and loss on ignition/LOI), and sieve on 45 µm residue of cement. This research is intended to find how insoluble residue/IR, loss on ignition/LOI, and the amount of SO3 will affect compressive strength of cement. Various percentages of IR, LOI, and SO3 in cement will result in different compressive strength. Taguchi Method is applied to determine material proportion. With Orthogonal Array calculation for 3 factors and 4 levels, it will result in 16 calculation running times (L16 4**3). In laboratory scale, cement for this research has been being manufactured and then its compressive strength for 3 days, 7 days, and 28 days will be measured. Determination of optimal proportion will be calculated by statistic method for higher compressive strength and lower manufacturing cost.

The purpose of this article is to describe the results of research models firebrick requirements planning in PT Semen Padang with MRP method. Firebrick is one of the spare parts and essential in the production of operational PT Semen Padang as protective and insulating of shell kiln. This article describes the firebrick requirements planning at all kiln Indarung II / III, IV and V to meet the needs of 2017 up to 2018. One type of firebrick most widely used in PT Semen Padang is spinal firebrick. Spinal firebrick highly susceptible to hydration and moisture as the main component is MgO compound that is hygroscopic so susceptible to damage in the form of cracks firebrick. Based on the research that has been done, get MRP application design that can be used in planning the needs of firebrick PT Semen Padang to come. Plans need firebrick for compliance in 2017 to 2018 : (a) item 422 purchased through two phases in the 4th month of 12.711 pcs and in the 9th month of 24.909 pcs (b) item 622 purchased through two phases in the 4th month of 21.185 pcs and in the 9th month of 41.515 pcs (c) item P22 purchased through two phases in the 4th month of 446 pcs and in the 9th month of 874 pcs (d) item P + 22 purchased through two phases in the 4th month of 446 pcs and in the 9th month of 874 pcs (e) item 425 purchased in the 8th month of 14.626 pcs (f) item 825 purchased in the 8th month of 20.600 pcs (g) P25 item purchased in the 8th month of 412 pcs (h) P + 25 items purchased in the 8th month of 412 pcs.

PT. Semen Padang is one of the cement producers competing to meet the needs of the cement. To that end, PT. Semen Padang must ensure the availability of cement on time, quantity, location and at competitive rates. One way to achieve this by optimizing the distribution system because it will be able to maximize sales and increase corporate profits. In this research, the distribution network planning model of PT. Semen Padang considering the cost of transportation, facility capacity, time, and uncertain demand. This model aims to minimize the total cost of product distribution and cost of opening the buffer warehouse and Packing Plant and maximize responsiveness to customers considering the uncertain parameters by using Fuzzy Multi-Objective Programming method. Based on the results of the research, had obtained the product distribution network planning model by using the fuzzy multi-objective programming method with the output is the opening of Packing Plant and buffer warehouse and the amount of product delivery to the final consumer with minimum cost and time of distribution. Search solution or output model assisted with Software Lingo 17.0. The designed model is able to explain the change of output if there are any changes in parameters covering demand between marketing areas, transportation costs between marketing areas and vehicle speed in transporting products from the last distribution center to the marketing area. The model can be implemented in the distribution network planning of PT. Semen Padang by using data in accordance with the conditions in the field.

Food business is a very promising, but the products must be safe and worth buying. Good manufacturing practices (GMP) are production practices which considering various aspects, such as preventing food contamination during the production process, and production control as well. Small and Medium Enterprises (SME) fostered by Andalas University, which is engaged in the field of food manufacturing, wants to find its products better known and with a wide sales distribution. This can be realized if the business owner has the trust of many consumers. One effort that can be done is to implement the GMP For this reason, SMEs need to receive GMP Training.The method of this event is in the form of training to socialize the concept of GMP for food SMEs fostered by Andalas University, as well as self-assessment of the application of GMP that has been carried out by each SME. The training was held in the presence of 50 SMEs assisted by Andalas University, on Thursday / December 5, 2019 at Amaris Hotel, Padang. Participants were very enthusiastic in attending and actively participating during the training. Self assessment results showed most SMEs have not yet implemented a good GMP in their industry.
