Abstract

The intensity of electrical energy consumption at the Denpasar District Court in 2020 is 133.84 kWh/m2/year. Based on the Minister of Energy and Mineral Resources Regulation No. 13 of 2010 on an air-conditioned building, the building is included in the wasteful category. So the Denpasar District Court office must make efforts to save money by conducting energy audits on lamps, coolers (AC), and other equipment. The purpose of this research is to analyze electrical energy opportunities and provide recommendations for savings that can be made. The method used in this research is descriptive quantitative by calculating the IKE of the building. The results of this study obtained the total energy needed in existing conditions (before the LED lamp and AC inverter were replaced) with the assumption that the lamp and air conditioner operated for 8 working hours per day and 24 days per month, the total energy was 140,101,344 kWh/year. Meanwhile, the total energy consumed after replacing the LED lamps and AC inverter is 124,328,448 kWh/year. So that there is a saving of 15,772,896 kWh of electrical energy for one year with a saving of electrical energy costs of Rp. 22,787,102.85 / year. IKE before replacing the LED lamps and AC Inverter is 41.462 kWh / m2 per year in the wasteful category according to the Ministerial Regulation ESDM No. 13 of 2012. Meanwhile, after replacing the LED lamps and AC inverter, the IKE obtained is 36,794 kWh/m2 per year in the wasteful category, but there are savings in electricity consumption and electricity payment costs.

Abstract

The increase in demand for electrical energy in Indonesia causes a reduction in conventional fuel reserves. This situation forces people to look for alternative energy sources or commonly callednew and renewable energy (RE). Seeing the geographical condition of the environment in Indonesiawhich has the potential for the development of electrical energy by utilizing the flow of water, it iscalled a Micro Hydro Power Plant (PLTMH). In implementing MHP, one type of impulse turbine canbe used, namely the Turgo turbine. This study focused on knowing the effect of variations in thenumber of blades on a turgo turbine on rotational speed, torque, voltage, current and power producedby PLTMH using a Turgo turbine, with variations in the number of blades used, namely 18,16,14,9,8,and 7 blades. The method used in this research is quantitative experimental, all combinations ofparameters tested get the result that the highest output characteristic value occurs using a runnerwith a number of 18 blades, where the voltage, current, and output power are 8.30 Volts, 0, 88Ampere, and 7.27 Watt. The fastest turbine rotation results are 782.8 rpm before being connected toa generator and 565.4 rpm after being connected to a generator, while the generator rotation resultsare 1062.4 rpm. The highest torque produced is 0.1Nm, the maximum efficiency obtained at therunner blade variation is 18 blades, which is 1.1%.

Abstract

Nadi Utama merupakan salah satu produsen sekaligus distributor jajan tradisional berlokasi di Desa Temukus, Kecamatan Banjar, Kabupaten Buleleng yang berdiri sejak tahun 2021. UD Nadi Utama memasang listrik PLN dengan kapasitas 2.200 VA dengan rata – rata pembayaran listrik sebesar Rp 750.000 perbulan yang dianggap terlalu membebani biaya produksi. Berdasarkan hal tersebut, UD. Nadi Utama memohonkan sebuah produk inovasi yang dapat menghemat pembayaran listrik. Setelah melakukan observasi, tim capstone project menemukan bahwa UD, Nadi Utama menghasilkan sabut dan tempurung kelapa sebanyak 25 kg perhari. Sabut dan tempurung kelapa tersebut merupakan hasil dari buah kelapa yang digunakan sebagai bahan baku produksi. Biasanya sabut dan tempurung kelapa tersebut dimanfaatkan sebagai bahan bakar tungku, namun dikarenakan kapasitas tungku hanya dapat menampung kurang dari 2 kg untuk 1 kali pembakaran, masih banyak sabut dan juga tempurung kelapa yang belum termanfaatkan dan terus menumpuk setiap harinya. Dari permasalahan dan potensi yang ditemukan di UD Nadi Utama, tim capstone project memberikan solusi berupa sebuah incinerator pembakaran sabut dan tempurung kelapa di UD. Nadi Utama. Incinerator ini memiliki perangkat konverter yang dapat mengkonversi panas yang dihasilkan dari pembakaran tersebut menjadi energi listrik menggunakan efek seebeck melalui modul peltier TEG SP 1848 27145 SA. Penelitian ini dilakukan menggunakan metode kuantitatif deskriptif. Dengan adanya inovasi ini, pengeluaran untuk pembayaran listrik di UD. Nadi Utama yang dapat dihemat adalah sebesar Rp 25.080,00 atau sebesar 3,34% dari rata – rata pembayaran listrik perbulannya.

Abstract

The grounding of the equipment at the substation switchyard location is given a layer of coral about 10 cm above the ground surface to reduce the tension difference on the ground surface and increase the resistance of the human feet around it. The purpose of this study was to determine the thickness of the coral in the grounding system of switchyard equipment in clay. This research analysis method calculates the results of the coral thickness value to achieve the step voltage and touch voltage values ??according to the IEEE Std 80-2013 standard so that it can provide safety for the equipment and people around it. The results of this study are that the thickness of the coral 0.15 meters produces a touch voltage value = 150.3675 volts (dry conditions) and 148.63 volts (wet conditions) and the step voltage is the smallest and best with a value = 206.83 volts ( dry conditions) and 163.98 volts (wet conditions when compared to the thickness of the coral 0.08 meters to 0.14 meters, so it is concluded that the thickness of the coral is best to be installed at the substation on clay of 0.15 meters is good when the soil and coral are wet or dry, so that it has an impact on the function of the grounding system to function properly and safely for equipment and humans. Keywords— Coral, Earthing, Clay.

Abstract

The horizontal axis wind turbine in the smart microgrid system at DH Building, Faculty of Engineering, Udayana University, is not operating optimally due to blade damage. This study aims to evaluate the replacement of the horizontal wind turbine with a tulip-type wind turbine and to analyze its economic feasibility. Simulation and optimization were carried out using HOMER Pro software, considering the local wind and solar energy potential. The simulation results indicate an annual energy production of 103,205 kWh, with contributions from the PV system at 61.5% and the wind turbine at 38.5%. From an economic perspective, the project yields a Net Present Cost (NPC) of Rp 1,668,925,000, a Levelized Cost of Energy (LCoE) of Rp 4,368.36/kWh, and a Payback Period of 16 years and 8 months. The feasibility analysis results in a Net Present Value (NPV) of –Rp 308,312,810.02 and a Profitability Index (PI) of 0.7635. These findings demonstrate that the project is not financially feasible under the PLN tariff of Rp 1,699.53/kWh and a discount rate of 8.5%.
