Indonesia Power as one of subsidiaries of PLN that is focused on generating using geothermal resource. One of the important components in the system of PLTP is a generator. PLTP Kamojang had been operating for about ±30 years, where there are still some problems that will reduce the efficiency of generator. The generator at PLTP Kamojang unit 2 must be operated more than 90% so that it will be able to supply electric power for 150kV. If the generator operated with the efficiency under 80%, so the supply of energy will not be maximum, because there are so much energy of electric lost caused by the losses in the generator. That is why needs to be analyzed toward the efficiency of the generator, whether the generator still works optimum or not. The result of analyses from the month of February 2019 as long as 1 month, found that the efficiency of generator unit 2 is about 92,888%. If comparing by the efficiency of generator as design as much as 98,4%. The efficiency value of the generator unit 2 Kamojang is decreased for about 5,51%. This condition showed that the generator still reliable one in supllying electric power.</p> 2019-10-06T00:00:00+00:00 ##submission.copyrightStatement## Penerapan Metode Triple Exponential Smoothing Pada Sistem Prediksi Keuntungan Bisnis Ayam Broiler Guna Meningkatkan Pengelolaan Keuangan Peternak 2019-10-10T09:10:47+00:00 Dine Tiara Kusuma Muhammad Farid Rifai M Yoga Sudirman <p style="margin: 0px 0px 10.66px;"><em><span lang="EN-ID" style="margin: 0px;"><span style="font-family: Calibri;">Profitable business predictions are used to help chicken breeder in anticipating profit earned in the next harvest.

In this case the 200 WP solar module is used as an experiment to see the symptoms produced during a certain time. The material of the solar module is silicon oxide crystal (SiO2). The process of converting solar energy into electricity can be affected by the angle between the rays that come with the solar module field. If the position of the solar module does not change throughout the day, this angle depends on the position of the sun or time. In this case, it is necessary to study how the angle that produces the most electricity is adjusted to the change in time in one day. The energy produced by solar tracking systems is more optimal than that of solar modules in an immovable state. Changes in the position of the solar module should be done once every half hour with a slope angle of </em>+5<sup>0</sup><em> from the initial position of the clock change. At the position of the solar module is not moving, the maximum power is at 12:30 a.m. which is 5.129 watts</em></p> 2019-10-06T00:00:00+00:00 ##submission.copyrightStatement## Kajian Harmonisa Pada Pemakaian Tenaga Listrik Gedung STT-PLN Jakarta 2019-10-10T09:06:41+00:00 Tony Koerniawan Aas Wasri Hasanah <p><em>Harmonic is produced by non-linear loads in electrical system.
