Abstract

ABSTRACT In general, the good or bad of the distribution and distribution system of electric power is mainly in terms of the quality of the voltage received by consumers. One way to increase efficiency is to reduce power loss and minimize voltage drop on the network. The results showed that the voltage drop that occurred at the PJXS substation PT. PLN ULP Bogor Timur is caused by two main problems, the first is that the location is far from the distribution substation and around the location has high loads. Prior to the implementation of the load rupture, the magnitude of the voltage drop that occurred at the PJXS substation PT. PLN ULP Bogor Timur has passed the ideal service limit set by PT PLN Persero, which is a minimum of 10% or 198 volts from the nominal voltage of the low-voltage network, which is 220 volts. The results of this new department have a good voltage value that is not below the standard voltage drop set by PLN, namely the service voltage value has a maximum value of 5% and a minimum of 10% of the nominal voltage of 220 Volts.

Abstract

Abstract Hotspot analysis at PMS Substation 150 kV Rawadenok Depok using the thermovision method was initiated based on hotspot events on Contact Finger phase S and Disconnecting Switch phase S. This analysis uses the Thermovisi Flir 400 tool as a means of checking high current temperatures that occur in Contact Finger phase S and Disconnecting Switches. The function of this thermovision is to measure the value of the ratio of the energy radiated by an object to the energy radiated by a black body at the same temperature and wave. Then measure the accuracy of Thermovisi starting from the value when checking, testing emissivity values, precision test values, accuracy values and repairs at hotspot points. From the results of the calculation of thermovision accuracy at Bay Cimanggis 1 & 2, it can be concluded that the temperature of the clamps and conductors shows that the conditions are still good. Where the RSM value of 27 samples is 0.4751, and has a coefficient variation (CV) of 0.1% and is categorized as good with a reference of no more than 2%, and has an accuracy value of 97.51%. Prior to the improvement of the hotspot points on Contact Finger it reached 115 oC and the DS Line S phase reached 103 oC after the temperature improvement returned to normal with Contact Finger reaching 36oC and the DS Line S phase reaching 31.2 oC.

Abstract

Abstrak The mechanical properties of clay shale are very unique. When dry it will shrink and harden, but when it absorbs water, it swells and to some extent loses its shear strength so that falling forces can occur suddenly even with its own weight. Due to its swell-shrink nature which is strongly influenced by climate and weather, the durability of clay shale can decrease over time when it comes into direct contact with air and water. Clay shale research was carried out in Hambalang, Bogor - West Java, Indonesia in the Jatiluhur formation, using weather stabilization stabilized with portland cement and excess compaction energy. with dynamic slaking (slake durability test). The dynamic slacking test was carried out three times, namely after sampling, 10, 20, and 30 blows/layer compaction were performed. With a low plasticity index, the durability research in Hambalang is classified as moderate to medium-high durability. Then, a test of excess compaction energy was carried out on variations in the stabilization of portland cement by increasing additional pressure. To determine the effect of the stabilization of portland cement with a composition of 5%, 10%, and 15% on clay shale, it showed an increase in the slake durability index, with the highest value in a mixture of 10% PC. The sample with an additional 15% PC and with an energy of 30 blow + pressure shows the highest Slake Durability Index value of 93.52%. However, this behavior cannot return to the original condition of clay shale (fresh clay shale). Keywords: Clay shale, durability, Slaking index, portland cement

Abstract

ABSTRACT The provision of a hotspot network at Gita Kirtti 1 Jakarta Vocational School was made based on problems that often occur in the learning activity, namely unstable internet speed when accessed by many users at once. This of course can disrupt the teaching and learning process, such as when accessing learning materials in the form of videos that require a stable internet speed, so that it can allow some students to open websites that are not related to learning which of course are not related to knowledge. This research aims to provide hotspot facilities for teachers and students at schools by utilizing Mikrotik routers in schools. This.research is using Queue Tree method. The method used to limit bandwidth is more complex than using a simple queue. Queue tree serves to limit bandwidth]on]a]Mikrotik that has.more than one.internet.connections. The]results;of.this study are]the availability of]a hotspot network that can be accessed by teachers and students at several points in the school that can be used to find information related to the world of education. There are different levels of user rights restrictions between teachers and students connected to the network. It is hoped that the school can maintain the hotspot network that has been provided so;that;it;can be useful as.a support for learning at school.
