Abstract

Energy is a major need in human life, but along with the population growth will be the availability of electrical energy especially that from fossil fuels are being reduced and insufficient for the needs of small-scale electric power listrik.Pembangkit potential as an alternative to fossil energy sources namely renewable micro hydro power plant availability of electricity in remote villages in the district of Bone Bolango is alarming, so it was done research on Analysis of Potential Development of micro hydro power plant (MHP) in Bone regency Bolango. This study aims to provide an overview and preliminary information on the potential of hydropower as a basis for planning and development of micro hydro power plant. In this research will be outlined potential sites for the development of MHP with power potential, specifications turbindan civilian buildings. Measurement of power was awakened by the amount of streamflow in Mongiilo Desa Ulu Subdistrict Bolango Bone Bolango District. Debit analyzed based on observation of the flow rate by using a current meter. From the analysis of the amount of power potential in getting aroused in the research area of 289,935Kw with ideal flow 12.14 m3 / sec, the average efficiency of 65% with the plan fell 3.75 m high. This power is sufficient magnitude elektrifitas needs of residents in the study area that is equal to 65kW.

Abstract

Hasil penelitian gradasii menunjukkan bahwa Campuran AC-BC yang di gunakan di lapangan dengan masing masing titik/Sta pengambilan sample nilainya masih di atas dan kurang dar isyarat spesifikasi dan JMF(Job Mix Formula)  yaitu 5.75%.Pada hasil gradasi Agregat material Klas B dan Klas A masing  masing titik/Sta tidak memenuhi atau melebihi syarat spesifikasi dan JMD  (Job Mix Design).Dimana telah di tunjukkan dari hasil penelitian masing titik/sta   Material KlasB 95.40 % - 92.67%  Dan pada  Material Klas A 60.79% - 50.70%..       Pada hasil pengujian core drill menunjukkan bahwa ketebalan aspal pada masing masing titik/Sta pengambilan sample  yang di lapangan tidak sesuai dengan spesifikasi yaitu nilainya masih  di atas dan kurang dari ketentuan spesifikasi.Dilihat dari masing  masing titik/Sta pengambilan sample pengujian yaitu 5.75 % .Maka dapat di lihat nilai tersebut tidak memenuhi syarat. The gradation result showed that the mixing of AC-BC which used in this research with each point/Sta of collecting sample is still above and less from the specification requirements and JMF (Job Mix Formula) 5,75%In gradation result aggregate of material class B and class A, each point/Sta is not fulfill or more than the specification requirements and JMD (Job Mix Design). It showed that from the research result each point/Sta material class B 95,40% - 92,67% and on Material class A 60,79% - 50,70%.From core drill test result showed that the asphalt thickness in each point/sta of collecting samples in the field is not appropriate with specification which the value is above and less from the specification requirements. It can be seen from each point/Sta which the test is 5,75%. So the value is not appropriate with the requirements
