Abstract

Petromax lamps have many disadvantages such as kerosene which is increasingly expensive and limited. Petromax lamps also produce pollution in the form of smoke produced which can cause disease. The danger of the petromax lamp is that it can cause a fire if there is negligence. But it is undeniable, people really need lighting from lights, especially at night. Therefore, an alternative plan is needed that can replace the petromax lamp by using other available energy sources. A lamp design using renewable energy that can be used throughout the day without the slightest cost in its use. One of the renewable energies available on earth that can be used to replace petromax lamps is energy that comes from the gravitational force of the earth. Due to the lack of knowledge about the use of gravity as renewable energy, a learning tool is needed that can be used especially by electrical engineering students to better understand the concept of gravity which is applied to a visual aid in the form of a gravity lamp.

Abstract

Public Street Lighting (PJU) is part of the utilities needed by the community. Public road lighting is needed to improve traffic safety, environmental safety and public comfort when driving, especially at night. This study aims to determine the light intensity and level of public street lighting (PJU) in Pematang Siantar City, especially Jalan Sutomo. The condition of Jalan Sutomo, Pematang Siantar City is a one-way street. In calculating the luminance intensity ( lux ) of public street lighting, a digital lux meter is used. The type and power of the lamp used for PJU on Jl. Sutomo Pematang Siantar City is a 60 W LED lamp. The height of the PJU pole on Jl. Sutomo in Pematang Siantar City is 9 meters in average with an arm length of 2 meters. The distance between a row of PJU poles is approximately 50 meters, with a road width of approximately 10 meters. The laying of the PJU on Jalan Sutomo, Pematang Siantar City, is by facing each other on each side of the road using a 1 arm lamp post.

Abstract

Grounding refers to the connection of an electrical equipment or installation to the ground so that it can protect humans from electric shock , and secure installation components from the danger of abnormal current voltages . This grounding system has low resistance properties, so that the overcurrent in the installation network can be flowed quickly to the ground to minimize damage to equipment in the building and protect the people inside. This study reviews the measurement of grounding around the earth at the efarina university. To find out the condition of the grounding resistance at each grounding, it is necessary to measure each grounding by measuring directly on the grounding installation network using an earth tester using an electrode pin. The calculation of grounding resistance is based on the type of soil, the depth of the electrode rod. The results show that the earth around the campus lobby has met the General Electrical Installation Requirements (PUIL) standard, which is smaller than 5 ohms. However, for earthing around the health faculty, it does not meet the PUIL standard, which is less than 5 ohms.

Abstract

In designing the backbone network for the province of West Kalimantan using Dense Wavelength Division Multiplexing (DWDM) and Optical Transport Network (OTN) devices which cover 14 districts and cities consisting of 30 segments, of which 30 segments consist of 14 DWDM OTN sites and 8 Optical Land Amplifier sites ( OLA). From the results of the design and simulation of the backbone network, it was found that the value of the Optical Link Power Budget (OLPB) < 50 dBm where this value is the ideal value in deploying a DWDM OTN backbone network, and the range of the Optical Signal Noise Ratio (OSNR) is between 20 dBm < OSNR < 40 dBm, which is the ideal value for OSNR, and has an Optical Rise Time Budget (ORTB) < 60 ps, and also has a segment margin system of > 7 dB.
