Abstract

Conventional cooling systems used in office buildings are one of the causes of ozone layer depletion and greenhouse effects. It requires the advancement of new technologies that are safe for the environment to be used in cooling systems in office buildings. Absorption cooling systems using solar thermal energy have many advantages by using non-destructive working fluids such as water, or in the form of saline solutions. This is a form of energy saving and safe for the environment. In order to obtain real and objective measurement data, testing is performed in two stages, namely the test equipment testing stage and the second stage is data collection when the test equipment is fully operational. The test equipment can be used in stand-alone systems or conventional air conditioners. In the test, it is known that the average percentage of solar thermal energy consumption per day is 40% of total energy so due to solar thermal energy consumption, the average COP value of this system per day is 2 and this value is greater than similar absorption cooling systems. conventional, then by knowing the value of solar energy consumption, can be seen the value of CO2 emissions reduction of 143.8 kg CO2 per day.

Abstract

Tersedianya air bersih bagi masyarakat khususnya wilayah pedesaan mampu mendorong masyarakat lebih kreatif, produktif, serta meningkatkan perekonomian desa. Prasarana air bersih belum sepenuhnya dimanfaatkan dengan baik oleh masyarakat yang tinggal di Desa Tejamari, Kabupaten Serang. Akses penyediaan air bersih yang berpihak dan terjangkau khususnya bagi masyarakat dengan ekonomi rendah yang masih terbatas menggerakkan tim untuk melakukan kegiatan pengabdian kepada masyarakat untuk bersama-sama mencari solusi permasalahan. Kegiatan ini merupakan studi awal program perwujudan infrastruktur desa dengan menemukan alternatif sumber air bersih. Berdasarkan aset serta potensi yang dimiliki desa setempat dan metode pendekatan asset-based community development, survei potensi dilakukan dengan objeknya yaitu Mata Air Cibojong. Berdasarkan hasil survei awal, diperoleh data debit sebesar 0,34 liter/detik. Data tersebut digunakan sebagai dasar dalam merencanakan sistem jaringan air bersih berupa bangunan penangkap mata air (PMA) dengan kapasitas tampung 5 m3 dan dua unit hidran umum (HU) komunal yang mampu menyuplai kebutuhan air bersih secara kontinu berkapasitas 60 liter/orang/hari untuk kebutuhan 30-60 kepala keluarga dengan teknik gravitasi. The availability of clean water for the community, especially in rural areas, can encourage people to be more creative and productive and improve the village economy. Clean water infrastructure has yet to be fully utilized by the people living in Tejamari Village, Serang Regency. Access to an impartial and affordable clean water supply, especially for people with a low economy, which is still limited, motivates the team to carry out community service activities to find solutions to problems together. This activity is an initial study of the village infrastructure embodiment program by finding alternative clean water sources. Based on the assets and potential of the local village and the asset-based community development approach, a potential survey was conducted with the object, namely the Cibojong Springs. Based on the initial survey results, discharge data of 0.34 liters/second was obtained. This data is used as the basis for planning a clean water network system in the form of a spring catchment building (SCB) with a capacity of 5 m3 and two communal public hydrant units (HU) that are capable of supplying clean water continuously with a capacity of 60 liters/person/day. 30-60 heads of families with gravity technique.
