Abstract

Lighting is one of the most important requirements of a building. This is because inadequate lighting of a space can affect the health and comfort of activities in that space. In addition to less important lighting, room temperature adjustments, room temperature adjustments have a significant impact on comfort during activities in the room. This magazine describes the lighting and room temperature control design of the CilacapState Polytechnic Welder Shop. The method used in this study is a quantitative method. This method calculates the required lighting and room temperature control and compares it with the standards. 2 rooms increase the number of light points and 3 rooms change the type of lamp with a higher lumen. There are 8 rooms that are recommended to use air conditioners with SNI 91714189. According to the SNI, the number of air conditioners and the capacity of air conditioners adjusts to the size of the room.

Abstract

Telecommunication Network Tower is a tower made of a series of iron profiles or rectangular or rectangular pipes, or rectangular long pipes intended to accommodate antennas and radio transmitters and receivers of telecommunications and information waves. In principle, BTS towers have the function of connecting network user communication devices to other networks. To support the smooth operation of the network, the building will remain solid and secure for a certain period. Investigation of the feasibility condition of the tower structure is very important to determine the overall condition of the tower structure. The methods used are hammer test, check bolt tightness (torque), measure slope (vertical), grounding, and visual observation. From the results of the test data obtained the average bolt tightness is 432.86 Nm. The tower slope test of 1.90 cm on leg A smaller than 3.6 cm is considered good because it is still within the tolerance limit of the bat slope, the average soil resistance measure smaller than1 ohm used is very good, and the visual physical conditions are very similar, so it can be done Tower in safe and working condition

Abstract

The Indonesian wood industry is diverse, with wood carving being one of its most popular products. However, the manual wood carving process is not suitable for large-scale production. To address this challenge, a new tool has been developed to increase the production of wood crafts, especially calligraphy carving. This tool is a 3-axis wood carving CNC router machine controlled by a computer and smartphone. The CNC router machine was designed using the CNC Shield V3 and the Arduino Uno R3 motor driver, A4988 as a stepper motor controller. The mechanism applied includes creating vector images programmed with gcode, controlling and engraving calligraphy through software on computers and applications on smartphones with Bluetooth HC – 05 communication with a maximum distance of smaller than 10 meters. Based on control data by computer testing geometry testing circle dimensions of 58 mm x 56 mm and feed rates of 5 mm/sec, 8 mm/sec and 10 mm/sec with engraving times of 01:12, 00:48 and 00:42. Testing Muhammad's carving with dimensions of 100 mm x 100 mm and feed rates of 5 mm/sec, 8 mm/sec and 10 mm/sec with engraving times of 05:22, 03:45 and 03:24. Tests for cutting 12 mm thick MDF wood with a depth 1.5 mm and a feed rate of 5 mm/sec cuts 8 rounds for 13:12 min/sec. The control data by smartphone testing the geometry of the circle with dimensions of 50 mm x 50 mm and a feed rate of 500mm/min with a carving time of 58:43 minutes. Testing Muhammad's engraving dimensions of 70mm x 60mm and feed rates of 500 mm/min, 800 mm/min, and 1000 mm/min with engraving times of 54:34, 39:25, and 35:28. The test for cutting 12 mm thick MDF wood with a depth of 1.5 mm and a feed rate of 500 mm/min-cut 8x rounds for 10:21 minutes/second.

Abstract

Land requirements are one of the obstacles to developing solar power plants . One solution is to utilize the surface of the reservoir for the construction of floating solar power plants. Excessive heat from sunlight received by photovolataics reduces the effectiveness of floating solar power plants output. Excessive heat in photovoltaics can be reduced by cooling methods. In this research, a photovoltaic cooling system using water was developed. A water pump is installed to channel reservoir water to the photovoltaic surface. The cooling system uses two methods, namely the sensor and timer method. In the sensor method, a sensor is installed on the solar power plants to detect the photovoltaic surface temperature. If the temperature detected by the sensor exceeds the photovoltaic effectiveness limit, the water pump is started. In the timer method, the pump is run based on a preset time. Based on the test results, the cooling system is able to increase the photovoltaic voltage output. The average value of the timer mode cooled photovoltaic voltage is 3.79% higher compared to the photovoltaic voltage without cooling and the average value of the sensor mode cooled photovoltaic voltage is 1.02% higher than the photovoltaic voltage without cooling.
