This study was conducted to determine mercury contamination contained in soils in Kalirejo sub-district, Kulon Progo, Indonesia. This contamination occurred as a result of traditional gold mining activities that used the amalgamation method of mercury. Soil samples were collected from 6 sites; one site was located in an uncontaminated location, and 5 sites in contaminated soil were taken from 10 meters distance from the tailing ponds. Samples were collected from each site at 30, 60, and 90 cm depths. Mercury concentrations in each sample were measured according to the US EPA method, using Mercury analyzer type VM-3000. Mercury concentrations in uncontaminated area at 30, 60, 90 depths were 0.19 mg/kg, 0.02 mg/kg, and <0.0001 mg/kg respectively. These values did not exceed the quality standard according to Government Regulation No 101 The Year 2014 concerning Hazardous Waste Management of 0.3 mg/kg. Meanwhile, mercury concentrations around the tailing ponds were 0.30 to 22.51 mg/kg, which exceeded the quality standard.

Kabupaten Muna Sulawesi Tenggara adalah salah satu daerah di Sulawesi Tenggara yang memiliki daerah tambang batu kapur yang berada di desa Meleura dan Labaha. Pemanfaatan batu kapur masih terbatas untuk memenuhi kebutuhan kapur bagi lahan pertanian. Pemanfaatan batu kapur dibidang konstruksi belum menjadi perhatian karena sifat mekanis batu kapur masih belum diketahui. Penelitian ini bertujuan untuk mengetahui sifat mekanis batu kapur muna sebagai agregat konstruksi melalui uji mekanis di laboratorium. Batu kapur diperoleh dari lokasi penambangan di desa Meleura dan Labaha. Batu kapur dipecah dan disaring menggunakan susunan saringan 11/2”, 1”, ¾”, ½”, dan 3/8”. Uji mekanis terhadap kedua batu kapur dilakukan dengan uji abrasi (SNI 03-2417-1991) dan impact (BS 812:part 3:1975). Selanjutnya hasil pengujian dibandingkan terhadap spesifikasi yang berlaku untuk agregat konstruksi. Hasil uji mekanis menunjukan bahwa batu kapur asal Desa Meleura Kabupaten Muna lebih keras dibanding dari Desa Labaha dengan nilai abrasi masing-masing sebesar 41,66% dan 79,51%. Batu kapur Meleura memiliki nilai Aggregate Impact Factor (AIV) sebesar 23,06% sehingga layak digunakan sebagai agregat untuk mutu beton kelas II (K125–K275). Penggunaan batu kapur Meleura sebagai agregat konstruksi jalan raya, masih dimungkinkan jika nilai abrasi batu kapur dapat diturunkan dari batas maksimal 40%.

Aggregate materials used in asphalt mixture is based on assumption which is materials came from the same sources, quality, and heaving the same specific gravity or almost same. There for the used of alternative filler in HRS mixture need to examinated to find filler content that produce the optimum asphalt content as reference of mix performance. This research conducted to HRS-Wearing Course type. Kind of alternative fillers in this research are hydrated lime filler and slag nickel filler. Material testing based on AASHTO/ASTM standard while filler content variation of hydrated lime filler and slag nickel filler are 1%; 3%; 5%; 7% and 9%. At each variation of comparison filler was made sample by asphalt content : 6,0%; 6,5%; 7,0%; 7,5% and 8,0%. Each specimen conducted the examination through the Marshall Test apparatus. Determination of the optimum asphalt content based on the narrow range method, conformed to the 2002 specifications of Kimpraswil Department. Result researched found that using filler content of 7% of hydrated lime can produce the optimum asphalt content (7.63%) and using filler content of 1% of slag nickel can produce the optimum asphalt content (6,75%). Stability value compare to dust filler is higher (1910.41 kg) than hydrated lime (1489.20 kg) and slag nickel filler (1525.40 kg) The value that is obtained from both fillers substitution is still fulfill the 2002 specifications of Kimpraswil Department for HRS-WC that is stability value recommended more than 800 kg.

This research aimed to utilize Anadara Granosa (Blood clam shell) clamshell waste as a new innovation in concrete technology and to investigate the effect of Anadara Granosa clamshell powder utilization as an aggregate substitution on the concrete compressive strength. The sample size was made of cylinders with a size of 10 cm x 20 cm with variations of clamshell powder 10%, 20% and 30% from the fine aggregate volume then soaked for 28 days as per the method of the Indonesian National Standard. The evaluation results exhibited that the slump value exceeded the slump value of normal concrete with a slump value of 0% = 160 mm, 10% = 165 mm, 20% = 180 mm and 30% = 180 mm. Additionally, it was found that the concrete compressive strength obtained post 28 days were 20.78 Mpa, 21.95 Mpa, 21.17 Mpa and 24.28 Mpa for normal concrete (0%), substitution concrete (10%), substitution concrete (20%) and substitution concrete (30%), respectively. Leading on from these results, it was concluded that the increment of Anadara Granosa clamshell powder substitution led to the increase of concrete compressive strength test.

Lalouesamba Village is one of the youngest villages in the South Konawe Regency, with a non-coastal slope topography of 82 meters above sea level and an area of about 4.1 km2. The majority are farming/gardening, coolies, and construction workers are the main occupations. Potential water resources include rivers with a width of 3-5 meters around the village. Each 1 artesian spot, boiling water spot, murky water borehole, and 5 units of wells with a depth of 15 meters. The problem with this village partner is that there is still a lack of access to clean water, so the solution offered to lift/pump the potential for river flow is to use a hydraulic ram pump without electricity & fuel. Therefore, this community service activity aims to provide an understanding of hydraulic ram pump knowledge and open insight into the potential for welfare due to the pump. The results of the transfer of knowledge of hydraulic ram pumps show a good indication with the achievement of the main material up to 80% based on the results of the feedback questionnaire and it can be stated that the villagers of Lalouesamba are ready to advance to the next stage, namely practical training on assembling/making hydraulic ram pumps. Requests for additional discussion from residents and village heads are evidence of the enthusiastic response, which is a sign of the opening of insight into the potential of hydram pumps for the welfare of villagers after receiving enlightenment about hydram knowledge
