Development of energy especially alternative energy and renewables continue to be encouraged, one of which is becoming the trend of the world today is focused towards the development of solar energy. The optimum angle of tilt of the photovoltaic panel is one of the deciding factor against the acceptance of the amount of solar radiation in the amount of the maximum, so that will affect the power output of a photovoltaic panel. Method of calculation of the Altitude angle is a way to find out the optimum height of the positions of the Sun, and these factors influence the position of the slope of the surface of the panel sector in the region, so by knowing the position of the right angle of the Sun will be able to obtain the maximum amount of radiation against photovoltaic panels. Adjustment of the angle of the slope against the monthly solar panels in the region of Meulaboh is affected by the angle of altitude. January and March, the optimum angle value starts from 35,54 ? to 12,39 ? . April does not occur, because of the angle position of the panel surface horizontal is same. May to December, the orientation of the panel turned south-facing surface of the panel with face down which is characterized by a negative notation.Keywords ? the photovoltaic panels, the altitude angles, optimal angle, orientation

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%.

This study uses moving average and exponential smoothing methods to predict the demand for Raskin rice in Banda Aceh. The Logistics Agency (Bulog) is a food institution in Indonesia that organizes a rice trading system, which functions to provide rice distribution services to the public. The fluctuation in demand for Raskin rice in Banda Aceh makes it difficult for Bulog to predict future needs. In addition, the excess supply of Raskin rice will also be very detrimental because rice is a staple that is perishable. Therefore, it is necessary to conduct research to predict the demand for Raskin rice in Banda Aceh. The results of forecasting or prediction by comparing two methods and three errors in forecasting accuracy, it can be concluded that the exponential smoothing method with α = 0.90 can be used to predict the demand for Raskin rice in Banda Aceh City. The prediction result of the demand for raskin rice in Banda Aceh is 92,407 tons, with an MAD error rate of 4.92, MSE 34.58, and MAPE 0.006%, or having the smallest value compared to the 7-month moving average method.

After turning into a state university, Universitas Teuku Umar continues to improve a number of infrastructures including the addition of a number of buildings. Currently the only source of electricity used to run all facilities in the building only from PLN, so that in the face of obstacles such as blackouts, suspension of electricity supply, or other technical constraints will result in the cessation of all activities so that it has an impact on the decline in the performance of the Faculty of Engineering in general. Research on the application of solar panels installed on the roof of the building (rooftop) as Building Applied Photovoltaic (BAPV) was conducted. The purpose of the study is to find out the number of solar panels and other devices needed for the application of PLTS in the Faculty of Engineering Building. PVsyst V7.2 software It is used to obtain daily solar radiation values at the locations reviewed. The existing Total Energy (TE) value calculation method is used to determine the capacity of solar panels and other supporting equipment. Results show an existing TE value of 20,422 Wh/day or equivalent to 20,422 kWh/day. Based on te value the number of solar panels needed as much as 33 units of capacity 120 Wp, Solar Charge Controller (PWM) 12 V-250 A 1 unit, VRLA Gel Battery Brand VOS 12V - 150 Ah 41 units, Inverter Pure Sine Wave (PSW) Split Phase Inverter Charger Series power 1-6 KW 1 unit.

Angle tilt is an important factor that affects the amount of solar radiation received on the surface of solar panels. Fixed-mounted solar panels cannot receive the maximum amount of solar radiation. How to get the maximum solar radiation by positioning the surface of the solar panel at a certain slope to be directly facing the sun. This study aims at determining the optimum slope angle of solar panels in the city of Meulaboh (4,152 LU, 96,131 BT). The method of calculating the total value of solar radiation on a sloping surface simulated with Pvsyst Software is used to determine the annual optimum tilt angle. NASA SSE solar radiation data from 1983 – 2005 were used to support simulations in this study. The results showed that the tilt angle that can produce the maximum output energy in the city of Meulaboh (4,152 LU, 96,131 BT, Johan Pahlawan) is at an angle of 5° with the orientation directly facing south.

Ideally the increase in electrical energy needs is proportional to the supply, but these conditions often cannot be met by the energy provider. This condition can affect the quality of electrical energy supply to customers, such as system outages to power outages. Short-term solutions and concrete steps in an effort to overcome these problems is saving electricity usage. In accordance with presidential regulation no. 5 of 2006 concerning energy conversion and the decision of the Minister of National Education No. 13 of 2012 about Savings on the Use of Electric Energy in government and private institutions, it is necessary to make efficient use of electricity in the University Of Serambi Mekkah Faculty of Engineering. There is no data on energy consumption in the building. It is necessary to conduct an energy audit of the building to determine the level of energy use in the building. The initial IKE value is a guideline for decision making whether or not a detailed audit is needed for the building. The audit results are Energy Saving Opportunities (PHE) that can be obtained by applying the optimal Energy Consumption Intensity (IKE). The results obtained energy savings reached 45.65% from the initial data.
