Abstract

A designer needs to simplify the bamboo cross-section shape variation to the closest standard geometry so a structural analysisof bamboo construction can be carried out. Bamboo culm’s cross-sectional geometrics vary and may be similar to conic such as acircle, ellipse, or egg-shape ring. The best-fit conic section, which is the most similar to the actual geometric shape of the bambooculm’s cross-section, should be considered. This study formulates mathematical equations for calculating the bamboo culm’s crosssectional properties (including the area, the first moment of area, the centroid, and the moment of inertia), which are fitted by acircle, ellipse, and egg-shaped ring. The thickness, diameter, major axis, and minor axis of four bamboo species (i.e., Gigantochloaapus, Bambusa vulgaris, Gigantochloa pseudoarundinacea, and Gigantochloa robusta) were measured, and thosevalues were substituted into the equations to produce the range of cross-sectional properties of each species.

Abstract

Solar panels are the main component of a solar power generation system, converting sunlight into electrical energy. This study develops a solar cell monitoring method to collect output data in a specific text format and uses solar cell modules to maximize the efficiency of solar energy absorption that moves from east to west throughout the day. The solar panel tracking system uses the Raspberry Pi 4 as the central controller to follow the sun's movement. It is supported by LDR sensors to detect light intensity and move the panel according to the direction of light. In addition, the BH1750 and BME280 sensors are used to measure additional factors, such as temperature, wind pressure, humidity, light intensity, and light angle, that also affect the panels' power production. The collected data is processed using fuzzy logic to convert the exact values from the sensor into fuzzy data, allowing for more precise control in panel position optimization. The results showed that the system can improve the efficiency of solar energy absorption, with an optimal intensity level of 53,999.99 lux in very bright conditions and a fuzzy-lux difference of 1.1%, which is lower than previous research, indicating that the system is more efficient and supports accurate real-time monitoring.

Abstract

The determination of industrial estates in Kasemen District has a significant influence on the area around the industrial area, especially on agricultural land, public green open spaces (RTH), and river borders around the industrial area. The methodology used in this study is the industrial location theory analysis method, the spatial analysis method of overlaying land use maps with spatial pattern maps of RTRW Serang City using QGis media, the method of analyzing the impact of determining industrial locations using leopod matrix, and the AHP SWOT method to analyze the direction of control. The location of the determination of industrial estates has been in accordance with the industrial location theory, changes in land use before and after the establishment of the RTRW regional regulation show a reduction in agricultural and fishery land, but the built-up land and mangrove forest land have increased and new land use has emerged including industrial land, service trade land. The identification of land use change occurred from 2009, 2016 to 2023. The results of the study show that the largest change in agricultural land use occurred in 2009 - 2016 of 833 hectares, while in 2016 - 2023 it was 90 hectares of land area in Kasemen District. This shows that after the establishment of the Serang City RTRW Regional Regulation, land changes in agricultural areas can be reduced to 0.01%.
