System Methodology

Currently, many coal-fired powers plants are built to supply electrical energy needs in Indonesia due to relatively inexpensive raw materials and abundant in Indonesia. Handling of coal is mostly done at the power plant using coal handling facilities consisting of ship unloaders, conveyor belts, stock piles, silos or bunkers. The problem that arises in the coal handling facility is dust from coal that fells or hovers in the air so that it can interfere with the environment and health both for workers in the Coal Power and residents around the Coal Power. The purpose of writing this paper is to eliminate the spread of coal dust that arises due to coal handling equipment that is not precise and imperfect. The method used is the Soft System Methodology (SSM), which is a systematic approach used to analyze and solve problems in complex and messy situations. This paper examines the benefits of applying SSM to knowledge management issues in handling coal dust at a power plant. Improvement is done by upgrading coal handling equipment (ship unloader, conveyor belt, stock pile) with the addition of dust suppression, proper sealing system, dust bag, and training to operators on the impact and handling of coal dust and coal handling equipment maintenance, so resulting in a significant decrease in the spread of coal dust, creating a working environment and the environment becomes clean, healthy and safe.

Nowadays, Indonesian government is focusing on build up infrastructures, especially power plant infrastructures to fulfil electrical energy needs. One of the power plants that will be built up is Waai power plant which located on Waai village, Maluku Province. Waai power plant had been postponed since 2014. In order to build this power plant, the advisability of the building needed to be checked from its verticality level. This level was determined by Terrestrial Laser Scanner (TLS). The TLS’s point clouds were registered using two methods, there are target to target and cloud to cloud methods. There are 65 beams on the power plant boiler building, but only 31 beams that used as the samples to assign the verticality of the boiler construction. The verticality level was set on the X-axis, Y-axis, and the resultant of the X and Y axis by using Pythagoras theorem after the bottom and top coordinates from each beam was determined. The Queensland Building and Construction Admission Standards and Tolerances Guide 2016 was used as tolerance of verticality level. The result of the verticality calculation presented on the X-axis consisted from -0ᵒ 1’ 26,678” to 0ᵒ 4’ 11,778” with the average was 0ᵒ 1’ 40,820” and major direction pointed the positive axis. On the Y-axis, the average was -0ᵒ 0’ 45,772” with -0ᵒ 3’ 33,345” as minimum and 0ᵒ 1’ 25,319” as the maximum and the major direction went to the negative axis. The verticality on the resultant of X and Y axis was from 0ᵒ 0’ 45,225” until 0ᵒ 4’ 15,674” with the average was 0ᵒ 2’ 27,057” and the direction was to the southeast. After the verticality number was compared with the tolerance, the verticality level was smaller than the standard on each beam. From the result, we can conclude that the boiler building on the Waai power plant can be categorized safe to reconstruct.

Hybrid Power Plant

Electrical energy is a basic human need and its use continues to increase, it is necessary to seek and utilize alternative to meet these energy needs, among others, by combining wind energy and solar energy. In its application, this hybrid power plant requires a battery as a storage medium and a controller as a regulator. There is a controller designed for the direct control type, where the electrical energy from the power plant to the hybrid source will not be directly channeled to the battery but through the MOSFET first, so that charging and disbursement of power consumption on the battery can be regulated. When the battery is fully charged, the system voltage controller will read the parameters to be adjusted and will disconnect the hybrid power source to the battery to prevent overcharge. The controller switches and regulates battery power usage to the load. The battery charging control system uses the PWM method using a MOSFET as the driving circuit and the ATMega 32 microcontroller as the system controller.

ABSTRACTElectrical energy needs are very important for villagers' activities in improving work productivity and education. For people who live in remote areas, such as Sepok Keladi, Sungai Kakap sub-district, Kubu Raya district, fulfilling electricity is a big problem. Because the PLN electricity network has not reached the area. Therefore, the most appropriate solution to overcome the absence of electrical energy in this area is to convert sunlight into electrical energy using photovoltaic technology (Solar Cells). The system for supplying electricity with this system is called the Solar Power Plant (PLTS). Currently,  PLTS is still classified as a power plant with an expensive initial investment. Therefore, installing PLTS is preferred for lighting. For these purposes, the use of lamps that require low power is very important. Energy-saving light Emitting Diode (LED) DC lights are one solution that can be applied to overcome lighting problems in remote areas that receive energy supplies from PLTS. With lighting, it can support social, economic and community education activities, especially at night. Keywords: PLTS, remote areas, LED lights, energy-saving. ABSTRAKKebutuhan energi listrik sangat penting bagi aktivitas warga desa dalam meningkatkan produktivitas kerja dan pendidikan. Bagi masyarakat yang tinggal di daerah terpencil, seperti dusun Sepok Keladi, kecamatan Sungai Kakap kabupaten Kubu Raya, pemenuhan akan energi listrik merupakan masalah besar. Oleh karena jaringan listrik PLN belum menjangkau daerah tersebut. sehingga solusi yang paling tepat untuk mengatasi ketiadaan energi listrik di daerah tersebut adalah dengan mengubah cahaya matahari menjadi energi listrik menggunakan teknologi photovoltaic (Sel Surya). Sistem penyediaan energi listrik dengan sistem ini disebut Pembangkit Listrik Tenaga Surya (PLTS). Saat ini PLTS masih digolongkan sebagai pembangkit listrik dengan investasi awal yang mahal,  Oleh karena itu, pemasangan PLTS lebih diutamakan untuk penerangan. Untuk keperluan tersebut penggunaan lampu yang memerlukan daya rendah sangatlah penting. Lampu light Emitting Diode (LED) DC hemat energi merupakan salah satu solusi yang dapat diterapkan untuk mengatasai masalah penerangan di daerah terpencil yang mendapat suplay energi dari PLTS. Dengan adanya penerangan dapat menunjang aktivitas sosial, ekonomi dan pendidikan masyarakat terutama pada malam hari. Kata Kunci: PLTS, daerah terpencil, Lampu LED, hemat energi
