The Klandasan Parking Building (GPK) is an 8-story parking built in Balikpapan that serves as vehicle parking and uses a conventional structure system (columns, beams, plates) where the highest beam is about 800 mm. To maximize the clearance of each story, an alternative structure system is planned by removing beams called flat slabs. The new plan is conducted by modifying the structure into a dual system which consists of an Intermediate Moment Resisting Frame, a flat plate with drop panels used to withstand gravitational loads on buildings and a Structural Wall System (SWS) installed to resist lateral loads such as earthquake and wind. Structure’s plan refers to SNI 03-2847-2013 and SNI 03-1726-2012 which are Indonesia’s concrete and earthquake codes respectively. In addition, PPURG 1987 is also used to determine loads for the building. The analysis result shows that the building could be changed from 8 to 9 stories using the same total height of 8 stories. The depth of plates and drop panels which are supported by interior and exterior columns are 250 mm and 100 mm respectively. Turning to the shear wall, a thickness of 350 mm can be used to resist lateral loads.

The rapid development of technology causes humans to provide a large amount of energy, especially electrical energy. One of the new renewable energy sources that is still under development is a piezoelectric-based energy harvester. Piezoelectric itself is a material that has an electric polarizing effect that occurs in certain materials when the material is given a mechanical stress. The potential difference measured across the piezoelectric material is proportional to the applied pressure. This study aims to examine the prototype of a piezoelectric-based micro energy generator using different loadings on ceramics. This research was carried out by making a prototype on a 30x30 cm2 ceramic, and using a piezoelectric in the form of a PZT type. The method used in this research is measuring the voltage of each configuration variation in the piezoelectric circuit. Retrieval of stress data was done by dropping a load of 3 kg, 6 kg and 9 kg for each variation to be tested. The distance between the piezoelectric position and the center of mass affected the resulting voltage, each additional load would cause an increase in voltage, and a series circuit produces a greater voltage than a parallel circuit

The era of globalization requires humans to continue to innovate in developing technology. The comfort factors of a room are largely determined by the location, characteristics and activities in it. Determination of the amount of power in the Air Conditioner is carried out based on the amount of cooling load obtained. The method used is data the collection of the outside temperature, the measurement of the area of the component to be calculated, and the heat transfer coefficient for the components used. The results show that the cooling load in the 104F lecture room of 21,133 Watt of equivalent to 72,109 BTU/h. While the cooling load in the 105F lecture room, the results are 13,444 W or equivalent to 45,873 BTU/h. From that finding, it can be concluded that the power of the Air Conditioner used in the two rooms has not covered the amount of existing cooling, because the 104F lecture room has three Air Conditioners whereas one Air Conditioner has a power of 2 PK or equivalent to ±18,000 BTU/h, and 105F have two Air Conditioners with the same power. So that the cooling load of the two rooms is greater than the power of the Air Conditioner used.

Gangguan pada sistem tenaga listrik bisa menimbulkan bahaya bukan hanya untuk peralatan tetapi juga manusia yang bekerja didekatnya. Gangguan yang dapat muncul mulai dari konslet yang menyebabkan percikan api, hingga hubung singkat yang dapat menyebabkan busur api. Tingkat bahaya busur api dapat diperkirakan untuk menentukan Personal Protective Equipment (PPE) yang harus digunakan oleh manusia jika bekerja di daerah beraliran listrik. Selain level PPE, nilai arus busur api juga dapat digunakan untuk menentukan jarak aman antara peralatan dan manusia. Penelitian ini mengambil data pada sistem distribusi 65 bus yang menjadi penyalur utama dekat beban, sehingga kehandalannya harus tinggi. Pengaman sistem menggunakan over current relay (OCR) dan ground fault relay (GFR) untuk melindungi sistem dari gangguan hubung singkat 3 fasa dan 1 fasa. Hasil simulasi menunjukkan bahwa OCR dan GFR dapat melindungi sistem dari gangguan hubung singkat yang dekat dengan lokasi relay. Semakin tinggi dekat dengan sumber, semakin tinggi pula level PPE dan jarak aman antara manusia dan peralatan listrik.

Current technological developments generally use sophisticated equipment which is categorized as a non-linear load. The massive use of non-linear loads causes side effects on the quality of electric power. Electric power systems that are connected to non-linear loads will experience distortion in current and voltage by harmonics due to the engineering of voltage waveforms due to the installation of many converters operating at frequencies that do not match the utility frequency of 50 or 60 Hz. Taking into account the great benefits for humans, the use of non-linear loads cannot be reduced but can be applied by keeping non-linear loads operating with good quality electric power. Therefore, harmonic filter equipment is needed to reduce harmonics. Passive filters and active filters can be used where active filters have many advantages compared to passive filters because they can adjust to varying working frequencies. To obtain more optimal harmonic reduction results, an active filter Shunt Active Power Filter (SAPF) using a PI controller tuned with the Gray Wolf Optimizer (GWO) optimization method is designed. The SAPF PI-PSO method is used as a comparison. The SAPF experiment on the IEEE 14 bus test system, PSO obtained better ITAE error results and computation time than GWO. The ITAE value and PSO computing time were 108.5821 second and 4255.097192 second, respectively, while GWO obtained 109.0172 second and 4379.461 second. However, the GWO-tuned SAPF is more able to reduce the THD of the 12 bus current on the IEEE 14 bus system by 13%.

Internet technology has changed the face of world communication, which has long been dominated by non-computer digital devices, into global computer communications. This condition is considered to have good implications for the digital economy. However, the uneven distribution of the internet so that some districts are not covered by the internet network is a problem to support the existence of a Digital Village.. The research method used consists of several stages, including; define literature study, determine data, determine problems, data preparation, data warehouse, exploration of BI power, data visualization and implementation. The factor causing the lack of optimization of the use of the Digides Application is due to the lack of distribution of BTS and internet access in the city of West Java. The attitude and policies issued by the government towards the law governing the equitable distribution of quality village growth development in Law no. 6 of 2014 concerning Villages has provided Legal Standing and a strategic foundation for the development and empowerment of rural communities, towards independent and prosperous villages.
