Abstract

Electrical system in the Central Java Province is managed by PT PLN (Persero). The Electrical energy distribution is carried by the APJ (Service Area Network). One of APJ operating in the Central Java Province is APJ Cilacap, APJ Cilacap which is responsible to fulfill the electricity needs in the District of Cilacap and Kebumen. It makes APJ Cilacap as manager of the utility company should be able to provide the energy needs of electricity in both area. In addition of electrical energy demand’s problem, the problems belong to SAIDI, SAIFI and line losses also becomes a problem of electrical energy distribution. Therefore, it needs to have the electrical energy planning so that energy needs, SAIDI, SAIFI and line losses can be known for the following years. In Preparation of Planning estimates that the software used are LEAP (Long Range Energy Planning System) version 2008.0.0.96. In Planning Making using two scenarios namely BAU (Base As Usual) is the result of scenario planning is still the same trend with the growth of base year or there is no policy affected and RPTL PLN which is based on RUPTL PLN (General Planning of Electricity Supply) in period 2012-2016. From the results of planning using LEAP, projected electricity supply, BAU scenario growth in electrical energy consumption, has the average value of customers equal to the Household sector in UPJ Cilacap, Majenang, Sidareja, and Kroya that is 0.41% per year, while the commercial sector, Industrial, and General are 5.39%, 2.33%, 4.60% per year, while UPJ Kebumen and Kroya for each sector 0, 51%, 4.27%, 7.40%, 4.48% per year. While the projections for electricity supply, outage rate index (SAIDI SAIFI), and losses, RPTL PLN scenario of electricity energy consumption growth follows a policy document RUPTL PLN year 2009-2019. Policy scenarios in RPTL PLN where the electrical energy consumption projections estimates the population growth of 0.3% per year, PDRB growth of 4.5% -5.83% per year, Electrification Ratio in 2019 is targeted at 97.5%, and 4.99% growth in connected power per year. For Policy in making electric energy losses in 2019 is targeted at 5.65%. While in making target of outage Index (SAIDI SAIFI) predicted value of SAIDI in the year 2019 at 77,44 minute/consument/years and the value of SAIFI in 2019 by 4,4 times /consument/years.

Abstract

Abstrak     Kebijakan energi nasional adalah mengarahkan upaya-upaya dalam mewujudkan keamanan pasokan energi.  Penyediaan tenaga listrik yang bersumber dari energi terbarukan di Indonesia merupakan keharusan.  Beberapa alasan adalah adanya keterbatasan energi listrik  yang berasal dari fosil untuk memenuhi kebutuhan listrik seluruh rakyat, dan kebutuhan listrik yang terus mengalami peningkatan seiring dengan peningkatan ekonomi rakyat, serta adanya ekspansi industri nasional. Propinsi Jawa Tengah bermaksud meningkatkan pengelolaan energi baru terbarukan (EBT), antara lain pengelolaan sumber daya air.  Sungai Damar Kabupaten Kendal secara fisik potensial sebagai lokasi pengembangan PLTM.  Pengolahan potensi sungai Damar adalah dengan penentuan kapasitas pembangkit listrik tenaga mini hidro sesuai dengan kondisi sungai Damar.  Mengacu penelitian, elevasi ketinggian antara calon bendung penenang dengan calon power house 144 m, dan tinggi efektif 135 m.            Debit aliran sungai Damar maximum 4,9 m3/dt, rerata 2,2 m3/dt, dan  minimum 300 lt/dt.  Daya yang mampu dibangkitkan pada debit maksimum 5184,83 KW, pada debit air 60% 2073,93 KW, dan pada debit air minimum 518,5 KW.  Kapasitas generator yang sesuai spesifikasi pabrik untuk PLTM sungai Damar sebesar 2454 KVA.   Kata kunci : pembangkit, debit, daya Abstract National energy policy has  to be  efforts to achieve security of energy supply. Electricity  supply from the renewable energy in Indonesia is very important.  Some of the reasons are the limitations of electrical energy  from fossil and increasing of the electricity for  the all the people,  the demand for electricity continues to increase along with the increase in people's economy, as well as the expansion of the national industry. Central Java Province intends to improve the management of renewable energy (EBT) as well as  the management of water resources. Damar River at  Kendal has   potential for the development of micro power plants. Processing potential is by determining the capacity of a mini hydro power plant in accordance with the conditions of the river Damar Referring to the study, the elevation height between the prospective weir  with potential power house is 144 m  and the effective height of 135 m. Damar maximum river flow is 4.9 m3/sec with average flow is 2.2 m3/sec. The minimum flow  is 300 liters / second. The Power that can be produced electricity around  5184.83 KW with maximum flow and will be produced 2073.93 KW at maximum flow  60%  . The minimum  flow can be produced electricity 518.5 KW. The capacity of the generator according to the manufacturer's specifications for micro power plants Damar is 2454 KVA . Keywords: power, flow, power
