Cathodoluminescence (CL) is generated by visible light of minerals when they are bombarded with a beam of high energy electrons by a cathode gun. There are two types of chatodoluminescence, i.e., cold CL and hot CL. In the cold cathode microscopic equipment, the electrons are generated by an electric discharge between two electrodes under a low gas pressure, whereas in the hot CL microscope, the electrons are generated by heating a filament (2000-3000Â°C). This research to propose determine the growth of oolitic limestoneâ€™s cement by cathodoluminescence analysis and itâ€™s implication to the engineering properties. Sectoral zoning and chevron-shape growth zoning exist in some coarse-grained calcite aggregates. The sectorial zoning of calcite as reflected by dull to bright CL color indicated as a water level fluctuation during cementation of the carbonate rocks, where the bright color of calcite indicating a shallower depth of water (oxidation) and dull to nonluminescence indicating a deeper level of the water (reduction). The results of this research, oolitic limestone (sample NS-1) showing sectorial zoning (chevron-shape) with at least 6 zonations, and have better engineering properties of other samples, according to SNI. 13-0089-87. Cathodoluminescence analysis is commonly used in the petroleum study, as evidenced in this research can be applied to determine the engineering properties of oolitic limestones in the study area.

Abstract Exploitation of natural resources through unlicensed gold mining (PETI) is not in accordance with mining operational standards occurring along the Noeltoko River, West Miomaffo Subdistrict, Timor Tengah Utara Regency, East Nusa Tenggara Province resulting in damage and environmental degradation. Changes and environmental damage include the formation of dug holes around the river flow, turbidity of water, changes in river flow. Other problems that arise are conflicts between these PETI workers and with other communities. This community service activity aims to provide an understanding to the community about the importance of maintaining and caring for rivers from excavation in the river walls that can cause debris / landslides explaining the impact of the use of hazardous materials such as mercury / mercury and cyanide, socialization of regulations regarding the formation of People's Mining Areas (WPR) ), introducing "sluice box" equipment to help the process of separating gold sand from sand. This activity was supported by the UPT ESDM Atambua Branch and was followed by 40 people who used to mine on the Noeltoko river. It is expected that the guidance and assistance can raise public awareness to be able to mine but still preserve the environment Keyword: PETI, Noeltoko, WPR, sluicebox, Abstrak Eksploitasi sumber daya alam melalui Penambangan Emas Tanpa Izin (PETI) tidak sesuai dengan standar operasional penambangan terjadi di sepanjang sungai Noeltoko-Kecamatan Miomaffo Barat, Kabupaten Timor Tengah Utara Propinsi Nusa Tenggara Timur yang mengakibatkan kerusakan dan penurunan kualitas lingkungan. Perubahan dan kerusakan lingkungan tersebut diantaranya terbentuk lubang-lubang galian di sekitar aliran sungai, kekeruhan air, berubahnya aliran sungai..

Landslides in many regions constitute serious hazards that cause substantial life and financial losses. To overcome and reduce the damages, efforts to monitor landslides are developed. One such technology utilizes a wireless sensor network (WSN). Results obtained from studies conducted in the Ikanfoti village, Kupang District, Nusa Tenggara Timur (NTT) Province (S 10o16’ 21.9” and E 123o40’59.8”) as pilot project, give result that the application of WSN can be applied properly. We detect and measure vibrations caused by landslides by vibration sensor (accelerometer) on Micaz devices. The results of this study indicate that changes in accelerometer values ranging from 0.2 g (gravity) to 0.49 g of either the X or Y of accelerometer indicate that soil begins to move but not significantly. Value above 0.5 g is a value that indicating a significant change of ground motion. The value of 1 g and above of ground motion indicates a very strong activity and should be alarmed. It is expected that this research provides the foundation for the application of WSN in various areas in NTT Province and Indonesia in general, for establishing thorough and reliable early warning system (EWS).

Abstract: This study using an interview for survey, respondents were asked a series of questions about their willingness to pay for environmental services as hypothetical research, which would assist in the conservation of water resources. Willingness to pay (WTP) for the owners who commercialized the well water using bidding game methods with offers of different starting points was asked to the respondents for the Groundwater Basin (CAT) Tabun-Bakunase-Haukoto-Sikumana, CAT Kupang-Oesapa-Tarus, CAT Penfui and Baumata, CAT Bolok-Tenau-Alak-Namosain. The results of the study showed that the value of Willingnes To Pay of the well owner was commercialized from 17 respondents who were willing to pay in the amount of Rp. 518.209 or Rp.6,100/m3. The average cost of production around Rp. 146.650/day, with the amount of discharged water that taken is 4.175 m3, with a cost per 5 m3 is Rp. 3.482, resulting in Rp.30.997 surplus for the producer. Consumer Respondent surplus towards payment of environmental services for commercialized wells water resources is Rp. 496.000,. The consumption of commercialized well water resources in Kupang on CAT Bolok-Tenau-Alak-Namosain is 150 m3/day or 54.750 m3/year, CAT Tabun-Bakunase-Haukoto-Sikumana is 2.600 m3/day or 949.000 m3/year, CAT Kupang- Oesapa-Tarus is 1.125 m3/day or 410.625 m3/year, CAT Penfui is 300 m3/day or 109.500 m3/year, and the amount of water withdrawal is less than the potential of groundwater in each CAT, so there is a surplus of water discharge that taken on CAT in the city of Kupang. The factors that influence the agreed response based on the test results indicate that the risk factors that have a low level of risk are Age (X1), Education (X2), Occupation (X3), Cost (X5), while risk factors that have a strong level of risk are Acceptance (X4) and Environmental Services Knowledge (X6). For Age risk factors (X1), Education (X2), Employment (X3), Costs (X5) have a low level risk level, this means that these factors are not risk factors that can pose a high risk on the willingness of the respondents to pay (WTP). While Acceptance (X4) and Environmental Services Knowledge (X6) have strong risk factors which means that these factors pose a strong risk to the willingness of respondents to pay (WTP), so that a significant effect is partially between acceptance and knowledge of environmental services to willingness of well owners in paying for groundwater environmental services that are used as economic goods. Acceptance and knowledge of environmental services have a significant effect because the greater the acceptance and knowledge of environmental services, the greater the willingness to pay for environmental services.

Penduduk Dusun Fatululat sangat kesulitan air bersih pada saat musim kemarau, sehingga harus berjalan mendaki sepanjang 2 km untuk mencapai embung penampungan yang airnya berwarna kecoklatan. Desa Fatumonas sendiri memiliki beberapa sumber mata air yang memiliki debit kecil namun tetap stabil mengalir. Mata air ini dapat diturap dan kemudian dialirkan ke penduduk desa termasuk Dusun Fatululat. Sebelum air ini sampai ke pemukiman dan dimanfaatkan, maka terlebih dahulu diuji kebersihannya. Air yang didistribusikan dapat memenuhi kebutuhan 45 KK di Dusun Fatululat. Tranfer ipteks dapat diterima oleh masyarakat yang tampak dari kemampuan masyarakat dalam melakukan perawatan pipa, menyambung pipa. Diharapkan ke depan masyarakat dapat membangun turap sendiri dari beberapa mata air yang belum dimanfaatkan karena jauh dari pemukiman.

Masyarakat di Desa Ekateta Kecamatan Fatuleu Kabupaten Kupang. Ada yang memiliki pekerjaan sebagai pemilah batuan yang mengandung logam mmangan (Mn). Para pekerja merupakan penduduk desa yang dilibatkan oleh suatu perusahaan yang memiliki Ijin Usaha Tambang (IUP) untuk memisahkan mangan dari batuan pengikutnya dengan cara “hand sorting”. Para pekerja ini tidak dilengkapi peralatan K3 maupun fasilitas dalam memilah mangan. Jumlah pekerja tidak menentu tergantung banyaknya tumpukan mangan yang digali oleh alat berat perusahaan. Permasalahan utama dari para pekerja adalah mereka tidak dapat memilah batuan mangan yang berukuran kurang dari 2 cm karena selain lebih mudah mengumpulkan batuan mangan yang berukuran lebih besar dari 5 cm. Metode kegiatan berupa penyampaian materi mengenai teknis penambangan mangan, K3 dalam usaha pertambangan, perhitungan ekonomis yang didapatkan jika bisa mengambil mangan yang berukuran kurang dari 2 cm menggunakan alat bantu mekanis berupa trommel screen dan log washer. Dampak dari kegiatan pengabdian ini adalah menimbulkan motivasi para pemilah untuk bermitra dengan kampus dalam menghasilkan prototipe alat yang bisa digunakan sebagai pemilah mekanis untuk mendapatkan batuanpembawa mangan yang berukuran kurang dari 2 cm.
