RFP Rumah Energi : Consultant for Biogas User Survey

1.      Background

The Indonesia Domestic Biogas Program (IDBP), or the BIRU (Domestic Biogas) program, is a development program managed and implemented by Hivos in partnership with Yayasan Rumah Energi (YRE) and national support from the Directorate General of New Renewable Energy and Energy Conservation. The overall development objective of the IDBP is to disseminate domestic biodigesters as a local, sustainable energy source through the development of a commercial, market oriented sector in selected Indonesian provinces.

By 21 September 2020, a total of 24.960 units bio-digester have been built in eleven provinces (Lampung, Banten, West Java, Central Java, DI. Yogyakarta, East Java, Bali, West Nusa Tenggara, East Nusa Tenggara, South Sulawesi, Central Sulawesi).  Plant construction and maintenance is the responsibility of Construction Partner Organizations (CPO) which are new or existing locally organizations.  Currently around 30 CPOs are working under a partnership agreement with IDBP. 

The Biogas User Survey (BUS) is an important instrument to measure the satisfaction rates of users towards biogas, to check the technical performance of the digesters and to use the result as the source of carbon monitoring of IDBP. The BUS also gives the programme management and stakeholders, including the users, good insights in the reliability and success of the biogas sector development approach as it is aimed on sustainable use of the biogas technology as introduced by the programme.

The functioning of the installed plants is an important aspect of the Programme, apart from the quantitative construction figures.  In addition, various direct and indirect but important benefits enjoyed by the users of biogas technology may be taken into consideration. It is imperative to know in what degree the users of biogas, who are the ultimate beneficiary of the programme, have derived benefits from their plants and the program as a whole and to what extent they are satisfied with the technology. It is equally important to assess the socio-economic impact brought about by this technology. Thus, in order to obtain necessary feedbacks about the technology, it is essential to monitor both the technology and its impact on user satisfaction by conducting appropriate and detailed surveys at regular intervals.

IDBP has been registered as a Voluntary Gold Standard Program of Activities in 2013. Biogas User Survey 2020 must be done where all parameters that refer to indicators which are related to the SDG Impact monitoring under the Gold Standard for the Global Goals (GS4GG). The User Survey will therefore also be used a Carbon Monitoring Survey in line with the monitoring requirements set forth under the Gold Standard.

For this purpose, IDBP will engage a suitable consultant to conduct the Users Survey for the current year 2020. For that reason the company will be engaged to undertake this 9th user survey after provided agreement is reached on price and contract conditions.

2. Objectives

2.1   General Objective

The main objective of the 9th Biogas Users Survey is to make a comprehensive assessment of the impacts of the biogas plants installed so far on energy, health & sanitation, and agricultural systems as well as technical, socio-economic, environmental and gender concerns. In addition to local impacts, the survey also should provide information to evaluate the global environmental impacts of biogas plants and include the additional parameters needed to measure the carbon emission reductions and other SDG impacts by the programme.

e.    Effect on productivity and cultivation of new crops


G. Energy, emission reduction and environmental Impacts


Biogas reduces the pressure on forests and alleviates deforestation as an average family size of biogas plant is considered to save more than 2.0 tons of fuel wood per annum. The digested slurry is an excellent source of bio- fertilizer that can significantly improve soil fertility and crop productivity. Besides, biogas can significantly reduce the level of Green House Gases emission in the environment. While assessing the energy and environmental benefit, major focus will be given on the following issues:

1.      Fuel usage before implementation of bio-digester: Household daily utilization of fire wood, agriculture residues, animal dung, kerosene, LPG for cooking expressed in kg/day/household.

a.      Fuel usage after implementation of bio-digester: Household daily utilization of fire wood, agriculture residues, animal dung, kerosene, LPG for cooking expressed in kg/day/household;

b.      Type of stove used.

c.      Daily gas production and consumption.

2.      Local (household) environmental condition before and after the installation of biogas and its impact on global environment.

3.      The number of animals kept by the household, per type.

4.      The manure storage methods, as per the definitions of the methodology.

5.      The animal housing methods.

6.      The usage rate, weighted based on drop off rates that are representative of the age distribution for project technologies in the total sales record*.

7.      Fraction of manure produced per animal type that is fed into the bio-digester.

8.      Fraction of manure produced per animal type that is not fed into the bio-digester.
