Less 81 million funds, currently 154 million have been collected.
Air, terang and books are three words that are uttered with confusion and longing by the residents of Kampung Katombu, Lenang Village, Umbu Ratung Nggay Subdistrict, Central Sumba.
Every day, most women and girls have to walk 2 km upholding water from a river. Only a small number are fortunate to use horses to transport water. When dry, the river is dry.
Generally, river water is not guaranteed cleanliness. Especially in this region, livestock also sometimes wallow in the river. Not all residents drink boiled water. It is conceivable, what are the consequences for residents who drink raw water from the river.
Dark Since Indonesian Independence
Since Indonesia gained its independence, in this village the light at night is only emitted by the moon and the lights. If there is a big event, then genzet is imported from outside the village. There are some houses that have SEHEN lights, but the quality is low, only last a few months.
Schools are expensive ideals for children in this village. Not only junior high and high school, the location of elementary and early childhood education was far from this village. Middle and high school children must leave their parents to go to school, and only return to the village on weekends. Schools and reading books become foreign goods which are far from the reach of children in this village.
If it continues, certainly the endless melancholy story will flow from the village which is home to 17 houses, 22 families and more than 100 inhabitants. On February 25, 2019, Alva Energi, the Harapan Sumba Foundation and the Central Sumba Volunteer visited the village to begin breaking this chain of sorrow.
The team surveyed the socio-economic conditions of local residents and the potential for renewable energy in this village. As a result, the immediate needs of this village are water, lighting and children’s learning houses.
Facilities and Fund Requirements
Considering the above conditions, Alva Energy as the technical team proposes the construction of ALVA Houses (Water, Electricity and Children’s Activities) which will accommodate batteries, inverters and charge controllers (PLTS system components), tank profiles for drinking water, and study rooms
To realize this plan, the funds needed are illustrated as follows:
Until now, Alva Energi has raised Rp. 154 million. This project still needs Rp. 81 million to meet all financing needs. The plan, construction will begin in July 2019.
On behalf of the children of Kampung Katombu (Lenang), who longingly await the arrival of water, light and learning house, with this the Harapan Sumba Foundation comes knocking on the hearts and good hearts of the benefactors.
All donations and their use will be delivered to Katombu villagers and published on the YHS website (www.projecthopesumba.or.id) as a form of transparency and accountability.

Technical Overview of Development
PLTS system that generates electricity for lighting and filters
Solar glass will be installed on the roof of the ALVA House and generate electricity from sunlight. The electricity generated will then be distributed to all villages for lighting and charging the mobile phones in each house. Batteries and electronic equipment located in the Clean Electricity Room, will ensure that electricity always flows in the village, even at night and rainy days for lighting citizens, and also to ensure the safety of the solar power system. Apart from lighting, PLTS will also provide power to the water filter.
Rainwater collection system to provide drinking water
Since there is no water source around the village, the most possible way to get water is from rain. The ALVA house will have a tin roof (which will not rust), like other houses in the village. This zinc roof allows water to flow down and be collected by bamboo pipes, and then stored into place
water storage, which is an underground water tank. To change rainwater into drinking water, there are several filtering mechanisms that will be applied.
1. The first water filter is a net located at the meeting point of bamboo pipes. This filter will filter out large particles or sedimentation.
2. The second water filter is a protrusion under the flow of the pipe to the reservoir, so that sediment will be filtered in the protrusion, and does not flow into the collection bank. This bulge will be easily accessed so that the collected sediment can be cleaned regularly.
3. Once a day the water will be pumped from the reservoir to the tank profile at a higher location. Tank profiles are equipped with taps for taking clean and safe drinking water. Between the tank and tap profiles is a two-stage filter that 1) filters finer sediments first, and in the second stage 2) removes material
chemistry with charcoal filters.
4. Right after the 2 stage filter there is the last filter, an ultraviolet (UV) filter to kill bacteria and ensure that water can be drunk. UV filters operate using power from a PV-VP system.
- Study room for children
One of the main concerns expressed by villagers and the Central Sumba survey team was the unavailability of books and spaces that children could use to learn.
Therefore, ALVA House will also have a learning room dedicated to children’s activities. Ideally, a teacher for PAUD will be trained or sent to the village so that young children do not need to be separated from their parents.
- Underground water reservoirs
Although drinking water can be obtained from rain water as described, Sumba has a very long dry season, sometimes lasting for 8 months, with 5 months without any rain at all.
Therefore, drinking water needs to be stored for 5 months. Assuming that each person needs to consume 3 L of water a day for 5 months, a 45 m3 water tank is needed for 100 villagers.
To ensure that no mosses or mosquitoes can live in a water reservoir, the tub must be completely exposed to light. And to prevent the breeding of bacteria, parasites, insects, or other organisms that might multiply in stagnant water, the water from the reservoir will be pumped into the tank profile every day. The profile size of the tank can be 3000 L, which is a lot of drinking water for the whole village for one day. There will be a switch to run the water pump from the underground reservoir to the tank profile, complete with instructions to only start the pump when the tank profile is empty, and to turn off the pump when the tank profile is full.
Apart from building ALVA houses and electricity distribution networks. Alva Energy also plans to:
1. Equipping residents’ houses that are roofed with zinc with a system
rainwater collection, but without water filters 2-4, for use of water not for drinking, such as for cooking, washing, etc. We also intend to provide these houses with tank profiles.
2. Look for other ways to cook salt more efficiently, get salt through other methods, or find other sources of income so that villagers no longer need to cook
salt by cutting down forests for fuel.
3. Experiment with more efficient stoves together with villagers. One candidate for the solution is Prime Cookstoves which are produced in Indonesia. Prime Cookstoves uses wood pellets, rice husks, or other solid biomass as fuel, without producing smoke, thereby reducing adverse health effects.
