Gunung Agung is one of the most potent eruption volcanoes in Indonesia. Reflecting back to 1963 when Mount Agung erupted, the impact was so devastating. Even the impact for months. The lack of food supplies is becoming a central job for the government. The distribution of logistics plays an important role in this regard whether it is food, clothing or other necessities, but the current logistics distribution system is still manual so it is not very efficient and very likely there is a misstatement. The impact of difficulties in managing logistical assistance can be seen, eg uneven distribution of relief goods in terms of number of inter-regions (posts), types of relief items sent are not in accordance with the type desired by individual posts, and especially for fast food, then damaged and outdated because it was sent to the post at the wrong time and improper handling. Needed a solution to minimize the problems that arise in the process of disbursing logistics disaster management is by using the Logistics Management Information System. In this research, the method used using two methods, namely waterfall method for system development, and for decision support system using Topsis method Expected to be able to manage logistical support in a timely, timely, and precise location

The quality of electric power is influenced by harmonic factors that occur due to animbalance in the load on the power system. This load imbalance results in a current at theneutral point. This amount of current can cause equipment damage and loss of electrical power.Therefore, an earthing system is needed to parse the current flowing at the neutral point and asa safety for the electric power system in a building. The objective of this research was to specifythe impact of the grounding resistance value of the neutral point on the current THD on theMDP installed during peak load conditions at the Electrical Engineering Campus of UdayanaUniversity in Jimbaran. This research method uses simulation with Simulink Matlab software todetermine the effect of neutral point grounding resistance on current THD in areas withcalcareous soils. The simulation outputs indicate that the value of the earth resistance affectsthe THDi value in the electrical system. The simulation outcomes represent that when the earthresistance value is 5 , the THD of the R, S, and T phase currents is feasible at 17.55%, 19.42%, and 8.86%. Then when the resistance value is lowered by 0.5, the THD of the R, S, T phasecurrents is feasible 17.20%, 17.35%, and 8.79%. This shows that more slight the earthresistance number, the smaller the current THD value.

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.
