Solar energy is often known by other terms solar energy is a form of renewable energy source. The potential of solar energy certainly affects the power generated in solar modules, there are several influences that cause solar energy not to be obtained optimally. In this study will be made mathematical modeling using multiple regression methods exposed to the angle of tilt and intensity of the sun with the research object of the polycristalline type solar module. The results obtained by calculating mathematically obtained the accuracy of the model with MAPE, as well as the adjusted value of R square of 0.960363563 which states that the percentage of the influence of irradiation-free variables and temperature simultaneously on the current obtained is very strong. While the results of calculations with double linear regression, the value of the regression coefficient on the irradiation variable (x_1) by 0.0000316, it means that if other variables remain and irradiation variables increase by 100 W/m2, then the current increases by 0.00316 A. Then the regression coefficient on the temperature variable (x_2) by 0.010573, this means if other variables remain and temperature variables increase by 1oC, then the current increases by 0.010573 A. From these results, it should be known the level of accuracy of the model which in this case uses MAPE. MAPE obtained on this model is 7.046%, this corresponds to the error standard of 0.007650294 with an average current measurement scale of Â±0.1 A. Thus, the MAPE results show that the model has an accuracy of 92.954%, which means that the modeling obtained is very good.

DKI Jakarta merupakan salah satu daerah perkotaan yang padat penduduk dan memiliki bangunan yang padat sehingga pemanfaatan atap bangunan dapat digunakan sebagai sumber energi. Salah satu gedung yang dapat menerapkan pemanfaatan energi terbarukan yaitu gedung administrasi di PT. PJB Unit Pembangkit Muara Karang. Pada gedung tersebut telah dibangun, namun pemasangannya belum optimal dikarenakan luasan pemasangan modul surya kecil sehingga kapasitas yang dihasilkan kecil pula, sementara potensi lokasi yang ada sangat luas. Oleh karena itu, perlu dikaji sejauh mana optimalisasi kapasitas pembangkit listrik tenaga surya pada atap gedung. Dari penelitian yang sudah dilakukan didapat hasil perlu dipasang modul surya sejumlah 143 modul panel surya, dengan kapasitas yang dihasilkan saat terpasang sebesar 42.900 wp dan didapatkan pula potensi energi yang dihasilkan sebesar 93.951 kWh/tahun atau sama dengan mampu menyuplai kebutuhan energi pada di gedung tersebut sebesar 75,11% dan rata-rata produksi harian sebesar 36,27 kWh. Agar potensi energi yang dihasilkan maksimal, perlu optimalisasi potensi dan besarnya luas atap pada gedung. Energi yang dihasilkan dapat semaksimal mungkin di manfaatkan sebagai energi listrik yang pada akhirnya dapat mengurangi beban biaya pemakaian energi listrik.Optimization of solar power plant capacity on the roof of the buildingDKI Jakarta is one of the densely populated urban areas and has dense buildings so that the use of building roofs can be used as a source of energy.

Solar cell panel technology is an alternative renewable energy source that utilizes energy from solar radiation to produce electrical energy, where one aspect that must be fulfilled is the determination of the placement location and the determination of the slope angle of the solar cell panel itself. The slope angle of the solar cell panel has a major influence on sun radiation exposure and where in each region the optimum radiation exposure of angle varies. At STT-PLN a solar power plant with a different slope angle has been installed. So it is necessary to evaluate the slope angle of irradiance in Monocristalline Type Photovoltaic Array, to observe the optimum angle of exposure to sunlight radiation field observations were carried out by taking several parameters which is angles varying from 0º to 65º with a gap per 5º, the value of the amount of radiation exposure, and the value current. Where the results of this observation found that the optimum angle in the STT-PLN environment from 0º to 65º is 25º angle with an average radiation exposure of 517 W / M² and the average current produced is 1.58 A. Keywords: Solar Power Plant, Slope Angle, Irradiance, Solar Cell Panel

The electric power system network must be maintained in its operation. The stability of the frequency in the balance between the power supply and the load is the main thing. In the event of a major disturbance, where many generating units are out of operation so that the system's generation capability is much lower than the load requirement, it can cause blackouts in the system. If this happens, the power system must immediately restore its generating capacity so that it can immediately serve the load or electricity users. In the simulation using DIgSILENT, it was found that the amount of load that must be sent by the Saguling PLTA to the Suralaya PLTU for the start-up process is 52.22 MW. And after the Suralaya PLTU is ready to operate, a recovery process is carried out on the 500 kV network by restoring GITET on the western system by paying attention to the frequency so that it returns to normal frequency. By using the software DIgSILENT 15.1.7. From the simulation results, the results showed that the Suralaya GITET recovered at a frequency of 50.072 Hz, 49.825 Hz at the Cilegon Baru GITET, 49.825 Hz at the Cibinong GITET, 49.953 Hz at the Bekasi GITET, and 50.064 Hz GITET in Cawang. While GITET Gandul at 49.866 Hz and GITET Kembangan at 50.078.

Sejak integral diperkenalkan oleh Newton dan Leibniz pada abad ke-17, alat ukur ini terus dilakukan kajian dan perumuman hingga saat ini. Terdapat tiga integral yang dikenal secara luas yaitu integral Riemann, integral Lebesgue dan integral HK. Pada masanya integral Riemann diterapkan untuk menyelesaikan berbagai persoalan tetapi kemudian diketahui memiliki keterbatasan. Integral Lebesgue muncul untuk mengatasi keterbatasan ini. Integral Lebesgue pun kemudian diketahui memiliki keterbatasannya tersendiri sehingga muncul integral Henstock-Kurzweil (integral HK) untuk mengatasi keterbatasan integral Lebesgue. Dalam banyak literatur seringkali untuk menyelesaikan soal integral tidak menggunakan definisi/ kerangka acuan yang sama sehingga sangat sulit memahami substansi maupun keterkaitan ketiga integral ini. Oleh karena itu, pada penelitian ini dilakukan perbandingan penyelesaian persoalan integral menggunakan definisi. Adapun dari empat persoalan integral yang dibahas, integral Riemann dapat menyelesaikan satu persoalan, integral Lebesgue dapat menyelesaikan dua persoalan dan integral HK dapat menyelesaikan seluruh persoalan yang dibahas.

Renewable energy sources have both renewable and sustainable properties and the utilization of renewable energy sources is a continuously developed alternative. One of the technologies that can utilize renewable energy is polycrystalline solar cells. Solar cells are technology that converts sunlight energy into electrical energy. This technology is very potentially applied in Indonesia that has a tropical climate, but the main problem of this system is the power instability generated. The power produced relies heavily on the intensity of the sun received by the solar panels. The intensity of the solar radiation received by the solar panels can be maximised by installing solar panels, with a precise tilt angle. In research acquired the relationship between irradiation and current correlates of R = 0.7251. From the correlation value above indicates that there is a strong link and is directly proportional between irradiation and the current obtained. The acquired Model needs to be seen its accuracy, in which case it will be used Mean Absolute Percent Error So it is obtained by 26.5%. This indicates that the model is good enough.
