What is a Micro or Mini hydro

Micro hydro is a term used for the installation of power using the energy of water, while micro means small and hydro means water. Micro hydro energy, also known as white resources and classified in the zero emission energy for electricity, while those in the fossil fuel CO2 emission factors have as much as 0.719 kg / kWh. Terms of emphasis to more sustainable activities that are not harmful, harmonious with nature and the rule-abiding principle naturally, when the activities associated with the term Micro Hydro development is the effort to produce energy in harmony with the rule-principle of nature .As the real action is to maintain the ability of nature to provide energy to the water at any time to protect and maintain watershed or catchment area around the generator, so that the plants are expected to operate throughout the period.

Besides the term of Micro-Hydro above, we also often hear the term of Mini Hydro that distinguishes them is Micro hydro with a range of resources raised. According to the National Standards Indonesia (BSNI), Micro hydro power is raised from a maximum of 50 kW and Mini-hydro above 50 kW to 5000 kW. In the group of M.H.P(Micro Hydro Power) and academics rarely have they segregated the restrictions, to a maximum of 100 kW for Micro-hydro and above 100 kW to 500 kW for Mini-hydro.

Microhydro Power Electric Prospect in Indonesia

By Ahmad Suhendra

Now Indonesia has producers 3rd rating CO2 emission at the world with totaled emission 3.014 ton milliards 1st rating is U.S.A 6.005 ton milliards followed by China on 5.017 ton milliards. This condition of causes Indonesia to constitute one of state which will emission big cost to state any other in interchange carbon (5 USD / ton carbon). Now have while it for Indonesian to fix sector energy it and downs absolute emission via effort more energy clear and extended with renewable energy promotion.

Scheme "on grid" unattractive for Investor since resulting energy of micro hydro or mini hydro is valued cheaper by "PLN" States electric firm ( on Java island Rp 432 / kWh) appealed by energy that resulting other source, accordingly payback period becomes longer upon five years. Investment that is embedded also overrisk since environmental damage, one that high enough that is 1,08 million hectares / year, who can threaten water for continuity of micro hydro so designing age be not been reached. For scheme "off grid" opportunity for investor because shan't sell electricity goes to PLN, but direct goes to consumer, especially to remote area that has no PLN electricity network. Click here

KERJA KERAS ADALAH ENERGI KITA (Hard work is our energy)

Awalnya kaget melihat tayangan di google adsense diblog saya tentang Pertamina Blog Contest , sungguh sangat menggelitik hati dan akhirnya saya bergabung untuk mengikutinya.

"Kerja keras adalah energi kita", mengandung makna yang dalam tentang etos kerja dan dari kecil kita sudah terbiasa mendengar slogan tersebut lewat berbagai macam istilah yang memiliki nilai rasa hampir sepadan seperti ; “ sedikit-sedikit lama-lama menjadi bukit”, atau “tetesan air pun dapat melubangi batu”, masih banyak lagi slogan serupa yang bisa digali dari khasanah budaya bangsa kita dan ini pula mencerminkan bahwa bangsa kita adalah pekerja keras/pejuang.

Sepanjang hidup saya cukup banyak daerah di Indonesia yang dijelajahi, terutama daerah-daerah terpencil, baru-baru ini saya mengunjungi saudara sebangsa di dekat perbatasan dengan Malaysia , sekitar 3 km dari perbatasan tepatnya di Desa Sungai Antu ( N 0⁰ 58’ 53.7” dan E 111⁰ 36’ 28.2”) Kec.Puring Kencana, Kab.Putussibau, Kalimantan Barat. Selama berinteraksi dengan penduduk setempat, cukup membuat hati ini miris melihat kehidupan mereka yang sangat jauh berbeda dengan negeri tetangga, jika di ibaratkan bagai bumi dan langit.

Jangan heran bila masyarakat disana berjuang keras untuk mendapatkan akses ekonomi maupun pendidikan di negeri tetangga dengan cara-cara mereka. Sebagai contoh untuk mendapatkan gas LPG buat memasak mereka harus melintasi perbatasan dengan menghadapi banyak resiko karena produk LPG negeri sendiri masih sulit didapat dan harganya terlalu mahal dibandingkan buatan negeri tetangga. Masyarakat telah bekerja keras untuk memperbaiki kehidupannya, akankah Pertamina mau bekerja keras demi bangsa ini? Kerja keras memang adalah energi yang tak terbatas selama hayat masih dikandung badan dan mampu merubah keadaan yang kadang tidak pernah terbayangkan oleh kita sebelumnya. Tidak ada kata terlambat dalam memperbaiki diri, saya yakin Pertamina dapat segera meraih kejayaan dan mendapat tempat dihati rakyat, karena saat ini banyak rakyat Indonesia sedang menantimu dengan sabar dan penuh harap di tapal batas keputusasaan akan pemenuhan kebutuhan energi dan semoga mereka tak terlalu lama menanti.

Electronic Load Controller For Microhydro System ( ELC )

This article intended to help people, by presenting a simple, low cost ELC that can be built from easily available components.

Use of ELC in microhydro system can help manage the load change with fast response. it's very similiar to the old mechanical speed governor that acts on a mechanical brake, only that an ELC uses electrical braking : dump loads into which excess electric power can be put. Click here

Industrial Biodiesel Plant Design and Engineering ( Practical Experience )

By Dan Anderson , Derek Masterson, Bill McDonald and Larry Sullivan

The biodiesel process itself is more than just a chemical reaction. The practical aspects of how to run an ordinary reaction in to a large full- scale industrial plant are of utmost importance. It has been proven that bench top reactions and equipment often to not properly scale up to full processing plant size, and biodiesel is no exception.

Welded Stell Penstocks (Engineering Monograph)

United States Department Of The Interior Bureau Of Reclamation

THIS MONOGRAPH will assist designers in the solution of problems in design and construction of safe penstocks which may be fabricated in accordance with modern manufacturing procedures. Certain rules relative to materials, stresses, and tests might be considered unnecessarily conservative. Safety is of paramount importance, however, and penstocks designed and constructed according to these rules have given satisfactory service through years of operation.

Welded Steel Penstocks presents information concerning modern design and construction methods for pressure vessels applied to penstocks for hydroelectric power plants. The data are based on some 40 years experience in penstock construction by the Bureau of Reclamation. During this period many of the largest penstocks in service today were designed and constructed.

The Errors that often occur in the design M.H.P

The error often made in the design M.H.P (Micro Hydro Power Electric) is:

1. Take a careless flow design through without consideration / calculation of hydrological cycle (region wide catchment rainfall, rainfall, watershed conditions etc.) in the area to be built Micro Hydro Power of Labor (M.H.P), so that the generator does not work optimally or decrease the age (under age design).

2. Penstock pipes placed in the area of unstable slopes, especially with the level slope more than 35% (landslide), so that placement in the penstock / analysis to be performed on the anchor structure of the soil strength

3. Making buildings intake (dam) that does not take into account / downstream flow of attention to scrape the dam foundation, that can be suddenly forebay (vessel) of water shortages.
