<![CDATA[Energi merupakan sesuatu yang kekal, tidak dapat diciptakan atau dimusnahkan, energi hanya dapat berubah dari satu bentuk energi ke satu bentuk energi yang lain. Sebagai alternatif dari keterbatasan energi fosil, manusia mencoba menciptakan alat pemanen energi (energy harvesting). Salah satu contohnya dengan memanfaatkan energi kinetik dari gerakan kaki. Komponen yang mampu mengubah energi kinetik menjadi energi listrik adalah piezoelektrik. Oleh karena itu, penulis merancang keset kaki pemanen energi menggunakan piezoelektrik dengan memanfaatkan energi kinetik dari kaki. Karena energi listrik yang dihasilkan satu keping piezoelektrik sangat kecil, maka dibutuhkan banyak keping piezoelektrik agar hasil yang diinginkan bisa tercapai. Energi listrik hasil dari rangkaian piezoelektrik akan dipanen dan disimpan oleh baterai lithium ion 3,7 Vdc dengan kapasitas 3000 mAh. Pada penelitian kali ini didapatkan hasil melalui sepuluh kali percobaan yang dilakukan terhadap tiga orang dengan bobot berat badan yang berbeda, yaitu 59kg, 61kg dan 65kg. Pengujian terhadap orang dengan bobot berat badan 59kg menghasilkan tegangan sebesar 1,907 V, untuk orang dengan bobot berat badan 61kg menghasilkan tegangan sebesar 2,138 V dan untuk orang dengan bobot berat badan 65kg menghasilkan tegangan 2,238 V, dengan total rata-rata tegangan yang dihasilkan adalah 2,094 V. Dengan kata lain, hal ini menandakan bahwa semakin besar tekanan yang diberikan terhadap piezoelektrik, maka akan semakin besar juga tegangan yang dihasilkan. Dan dibutuhkan 82,840 x 106 kali tekanan terhadap keset kaki tersebut.]]>

<![CDATA[Gas Insulated Switchgear Extra High Voltage (GISTET) is a power system component that has a function as a distribution center (transmission) that connects the extra high voltage transmission system through distribution channels or substations. Based on the installation of GISTET equipment, relying on hexafluoride gas (SF_6) as an insulating medium on the equpment. Equipment at GISTET is not always in good condition, GISTET also often experiences problems. One of the distrubances that GISTET often experiences is the leakage of SF6 gas at the PMT (circuit breaker). This requires a treatment called a GISTET overhaul. So in this paper the author will analyze the SSF_6 gas leak as insulation on the PMT (circuir breaker) at GISTET Saguling. According to the results of the calculations in this final project, the gas pressure of SF_6 and the breakdown voltage of PMT are interrelated. At the pressure when the gas leak occurs is at a value below 5kgf/cm2it is able to with stand the voltage. Penetrating with a high value so it is very effective to reduce arc fire. In addition, the SF_6 gas pressure is also related to the arc speed because the lower the pressure value at the time of gas leakage, the arc speed decreases, so the arc will be slow to muffle.]]>

<![CDATA[Gedung Fakultas Psikologi Universitas Jenderal Achmad Yani (Unjani) merupakan gedung perkuliahan yang berada di lingkungan kampus Unjani dan belum memiliki instalasi sistem jaringan indoor. Kondisi tersebut menyebabkan level sinyal yang terukur di dalam gedung memiliki nilai RSRP lebih kecil dari -110 dBm. Level sinyal tersebut termasuk dalam kategori kualitas sinyal 4G yang kurang baik. Selain itu faktor lain yang menyebabkan pelemahan sinyal ialah material dan konstruksi bangunan tersebut. Oleh karena itu, agar user pada gedung tersebut dapat terlayani dengan baik, solusi yang dilakukan adalah melakukan perencanaan jaringan Indoor Building Coverage (IBC) 4G. Berdasarkan perhitungan coverage planning jumlah antena yang diperlukan dalam perencanaan sebanyak 14 antena yaitu lantai 1 dan 4 masing-masing sebanyak 3 antena, lantai 2 dan 3 masing-masing sebanyak 4 antena. Berdasarkan hasil simulasi pada software RPS diperoleh persentase nilai rata-rata nilai RSRP >-90 dBm sebesar 89,93 % dan persentase rata-rata nilai SINR >3 dB sebesar 87,95 %. Berdasarkan hasil simulasi tersebut didapatkan bahwa hasil perencanaan yang telah dibuat telah memenuhi standar operator dan dapat diterapkan untuk memperbaiki coverage dan meningkatkan level sinyal di Gedung Fakultas Psikologi Unjani.]]>

<![CDATA[The classification carried out by the Gaussian Naive Bayes Classifier algorithm can use continuous data such as the parameters that are considered when a tsunami occurs. The data collected for the classification process is some earthquake data that has occurred in Indonesia in the last 20 years. Data from the occurrence of earthquakes that are taken include the time of occurrence, the place where the earthquake occurred, the magnitude of the earthquake, the depth of the earthquake, and also the distance from the epicenter to the nearest city where the earthquake occurred. The parameters needed in implementing the prediction process are the average value of the magnitude, the depth of the epicenter, and the distance to the epicenter. Next, the values of each standard deviation of magnitude, depth of the epicenter, and distance of the epicenter are also required. The microcontroller can implement the Probabilistic Density Function equation to calculate the potential for a tsunami. the microcontroller-based Gaussian Naive Bayes Classifier algorithm with the classification "Tsunami Potential" and "No Tsunami Potential" has an accuracy of 96%.]]>

<![CDATA[In the distribution system, blackouts caused by excessive loads cause losses for both consumers and electricity providers. Based on this, it is necessary to analyze the addition of distribution substations using an accurate methodology so that when applied it can be a solution to the need for electrical energi. Several stages of the method are determining the specifications of each component, calculating the optimal capacity of each component, measuring the voltage value contained in the panel and the primary part of the transformer at the hook-up substation, and simulating using ETAP software. The cantol substation was chosen because field studies have been carried out according to load requirements. The results of the calculation analysis show that with the addition of insertion substations, the total power becomes 100 kVA. The measured load at night is 77.7 kVA and during the day is 67.5 kVA. This indicates that the loading is in the allowable standard range below 80%. The voltage increased to 0.9828 per unit from the previous condition where there was a voltage drop of 11%. So that the load needs are met on demand.]]>
