<![CDATA[Housing development in Indonesia, especially in Sukabumi, in the last few years, many simple houses of type 30/60 have been built as a type of simple house that has received subsidized KPR facilities and is the type of house most sold in Indonesia. The problem studied in this study is that there is no incentive provided by the government to encourage the use of PV Rooftops. This study aims to see a comparison in the process of using PV rooftops with the installation of PLN electricity in the Home Ownership Credit (KPR) scheme, especially for subsidized KPR, which is the prima donna of housing in Indonesia today. So that it can provide input on what incentives should be done by the government. The method used is a comparison of the life cycle costs between the use of PLN electricity and PV Rooftop. From the results of the cost analysis carried out financially, this design has not been profitable from a financial point of view due to the high credit interest rate, namely 10%. Therefore, there needs to be a credit interest subsidy so that it can decrease to 5% -8% to obtain benefits compared to the use of electricity from PLN.]]>

<![CDATA[Indonesia is an archipelago with many small islands, which are in remote locations. Most of the inhabitants of these small islands earn a living as traditional fishermen. One of the obstacles faced by traditional fishermen is the availability of ice blocks as a fish cooling media. The availability of electricity is also a problem because it depends on the availability of diesel fuel as generator diesel power plant. This research aims to design a smart microgrid system based on renewable energy that is expected to function as an electricity supplier for local ice factories that can meet the needs of fishermen's ice on remote islands. This research takes place in Karimunjawa where is a small island which is majority of the population is work as a fisherman. The optimization of the design made is support by the use of HOMER software. From the simulation results obtained a system design consisting of: 5 kWp PV, 3 kW biobased diesel engine generator powered by coconut oil, 5 kW bi-directional inverter, and 16 pcs 100Ah / 12V batteries used to supply an ice machine load of 4 kW.Indonesia merupakan negara kepulauan dengan banyak pulau-pulau kecil yang sebagian besar penduduknya bermata pencaharian sebagai nelayan tradisional. Salah satu kendala yang dihadapi nelayan tradisional tersebut adalah ketersediaan es balok sebagai media pendingin ikan hasil tangkapan mereka. Selain itu ketersediaan listrik juga menjadi masalah tersendiri akibat masih sangat bergantung terhadap ketersediaan solar sebagai bahan bakar PLTD. Penelitian ini bertujuan untuk merancang sebuah sistem mikrogrid cerdas berbasis energi terbarukan yang diharapkan dapat berfungsi sebagai penyuplai listrik untuk pabrik es lokal yang dapat memenuhi kebutuhan es nelayan di pulau terpencil. Penelitian ini mengambil lokasi di Karimunjawa sebagai salah satu kepulauan terpencil dengan mayoritas penduduknya bekerja sebagai nelayan. Optimasi rancangan yang dibuat dibantu dengan penggunaan perangkat lunak HOMER. Dari hasil simulasi yang dilakukan diperoleh rancangan sistem yang terdiri atas: 5 kWp PV, 3 kW biobased diesel engine generator berbahan bakar minyak kelapa, 5 kW bi-directional inverter, dan 16 buah baterai 100Ah/12V yang digunakan untuk menyuplai beban mesin pembuat es sebesar 4 kW.]]>

<![CDATA[Application of solar adsorption refrigeration systems has developed significantly since 1980’s. Although it has some advantages like noiseless, non-corrosive and environment friendly operation (because solar energy is one of green and renewable energy), but until now the application still cannot compete with the traditional vapor compression refrigeration systems. Fortunately, due to the increasing of awareness about ozone depletion and global warming, green technology including solar adsorption refrigeration systems still becomes priority research is developed by some country. Recent research in application of solar adsorption refrigeration systems not only focus in how to increase the coefficient of performance (COP) like the use of various collectors or working pairs but also how to implement the systems so that suitable with the location that it will be applied. Nowadays, application of solar adsorption refrigeration systems mostly varies into 3 categories: ice maker, cool chamber and humanitarian aid. And the application’s usage usually implement in remote area that far from grid electricity.]]>

<![CDATA[Drinking water is a very basic basic need, and cannot be replaced by other elements. The needs of living things for drinking water are very many, not only needed by humans but also needed by animals and plants. To produce good and quality drinking water in accordance with health standards that have been set by the Regulation of the Minister of Health of the Republic of Indonesia No. 492 / MENKES / PER / IV2010, a proper water treatment process is needed. This research activity is aimed at designing a filtration device that is able to process dirty water into clean ready-to-drink water using reverse osmosis (RO) technology. The parameters tested are biological, physical, and chemical parameters in accordance with the requirements for good drinking water set by Permenkes No. 492 of 2010. This study used 3 water source samples to be tested, namely: the first sample was a relatively clear and odorless water sample but the bacteria content was above the standard, the second sample was turbid but odorless water, while the third sample was odorous water. After going through the filtration process with the tool made, ready-to-drink water is able to be produced with the condition that the bacterial level (total coliform) drops from 200/100ml to 0/100ml. In addition, the turbidity level also dropped from 8 NTU to 0 NTU, and the water condition also changed from smelly to odorless. So it can be concluded that the filtration device made and tested is able to produce readyto-drink water according to the standards of Permenkes No. 492 of 2010.]]>

<![CDATA[Double ring infiltrometer is a tool to measure the rate of infiltration into the soil. The design of the double ring infiltrometer has 3 stages, the first using 304 stainless steel material, the next stage is the rolling process using a rolling machine 6 × 1300 mm BB613RL, and the last stage is the welding process using TIG welding. The effect of adding sand on changes in the infiltration rate that occurs in the two rings, in this change the slowing of the infiltration rate does occur because the sand blocks the infiltration of water directly into the soil. However, the slowdown in the infiltration rate that occurs tends to be very small so that it can be said that it has no significant effect on the infiltration rate without sand. The results of the measurements showed that the initial and constant infiltration rates slowed down with a change in the average infiltration rate that occurred, namely 0.005 mm/s at the initial infiltration rate and 0.002 mm/s at a constant infiltration rate. Thus it can be concluded that the addition of sand as a ground cover does not have much impact on the rate of water infiltration into the soil, especially in the direction of water infiltration perpendicular to the soil. So that this sand can be said to be a safe material to use as a ground cover compared to concrete, castings, or asphalt.]]>

<![CDATA[In Indonesia, currently the problem of water infiltration into the ground has become a major problem in various areas, especially urban areas. One of these problems is influenced by changes in land use due to growth and increased population activity. In general, in Indonesia the transfer of land use from green open spaces to buildings. As a result of the lack of a good water absorption rate can cause many flood disasters. To prevent flooding, knowledge about the rate of water infiltration in an area is important. To measure the infiltration rate, infiltrometer technology is needed. The design of the double ring infiltrometer has 3 stages, namely first using 304 stainless steel material, the next stage is the rolling process using a 6 × 1300 mm BB613RL rolling machine, and the last stage is the welding process using TIG welding. The effect of adding a mixture of coconut coir and sand on changes in the infiltration rate that occurs in both rings, in this change the slowing of the infiltration rate does occur because the mixture of coconut coir and sand blocks water infiltration directly into the soil. Thus it can be concluded that the addition of a mixture of coconut coir and sand as a ground cover does not have much impact on the rate of water absorption into the soil, especially in the direction of water absorption perpendicular to the soil.]]>
