Desa Fatunisuan terletak dalam wilayah Kecamatan Miomafo Barat, Kabupaten Timor Tengah Utara, Provinsi Nusa Tenggara Timur yang identik dengan topografi berbukit-bukit dan terletak di dataran tinggi. Berdasarkan hasil riset, di Kecamatan Miomaffo Barat secara menyeluruh terdapat jenis tanaman jeruk keprok dan umbi-umbian. Riset khusus untuk mengidentifikasi dan menginventarisasi jenis tumbuhan endemik dan bemanfaat di Desa Fatunisuan belum pernah dilakukan hingga saat ini. Tujuan penelitian ini adalah untuk mengidentifikasi jenis tumbuhan endemik dan bermanfaat dari kelompok tumbuhan tingkat tinggi (phanerogamae) dan karakterisasi senyawa metabolit sekunder yang terkandung dalam ekstrak daun tumbuhan tersebut. Metode penelitian yang digunakan merupakan mix method antara eksplorasi dan eksperimen. Metode eksplorasi untuk mengidentifikasi jenis tumbuhan, dan metode eksperimen dengan uji skrining fitokimia untuk karakterisasi jenis senyawa metabolit sekunder. Hasil penelitian ini menunjukan bahwa di desa Fatunisuan terdapat tujuh jenis tumbuhan yang endemik dan bermanfaat bagi masyarakat desa setempat yakni Santalum album var. largifolium Rudjiman et Adrie, Santalum album L. var. album ziphus mauritiana, Pinus merkusii, Piper majusculum Blume, Coffea arabica, Arenga pinnata, dan Aleurites moluccana. Hasil karakterisasi jenis senyawa metabolit dari ke tujuh ekstrak daun tumbuhan tersebut dapat diketahui bahwa ekstrak daun Santalum album var. largifolium Rudjiman et Adrie maupun Santalum album L. var. album ziphus mauritiana dan ekstrak daun Coffea arabica memiliki kandungan lima jenis senyawa metabolit sekunder yaitu Alkaloid, Fenolik, Saponin, Flavanoid, dan Triterpenoid. Ekstrak pelepah daun Arenga pinnata maupun daun Aleurites moluccana memiliki kandungan lima jenis senyawa metabolit sekunder yaitu Alkaloid, Fenolik, Steroid, Saponin, dan Flavanoid. Sementara itu ekstrak daun Pinus merkusii memiliki kandungan enam jenis senyawa metabolit sekunder yang terdiri dari Alkaloid, Fenolik, Saponin, Flavanoid, Triterpenoid, dan Tanin. Sedangkan ekstrak daun Piper majusculum Blume memiliki kandungan lima jenis senyawa metabolit sekunder yaitu Alkaloid, Fenolik, Steroid, Saponin, dan Tanin
The community carries out bathing and washing activities directly in the retention basin which can cause polluted water. Water quality checks need to be carried out before treatment. The purpose of this study was to determine the quality of water in the retention basin. Determination of the sampling location by purposive sampling. Sampling was carried out once in August 2021. Parameter measurements were carried out in the field and in the laboratory. The measurement results are compared with the quality standards listed in the Regulation of the Minister of Health of the Republic of Indonesia Number 32 of 2017 concerning Environmental Health Quality standards and Water Health Requirements for Sanitary Hygiene, Swimming Pools, Solus Per Aqua and Public Baths. A parameter that passed the quality standard was E-Coli while pH, hardness, nitrate, temperature, and TDS still met the quality standards. Retention basin water in Tubuhue Village seen from the parameters of temperature, pH, TDS, hardness, and nitrate can be used for sanitation hygiene purposes, but judging from the parameter E-Coli cannot be used for sanitary hygiene purposes.
East Teba Village has limited water availability due to the relatively long duration of the dry season, so the villagers use rainwater puddles for various activities, including consumption (source of drinking water) for livestock. This study aims to determine the quality of water in puddles of rainwater for consumption (source of drinking water) livestock. This research is quantitative descriptive. The sampling point of the test is the point where livestock drink water. Sampling test based on SNI 6989.57:2008 regarding the method of sampling surface water. The test result data is compared with the quality standard and the quality status is calculated using the pollution index method. The results showed that the TSS value had exceeded the class 2 and class 3 quality standards, while the BOD value had exceeded the class 2 quality standard and still met the class 3 quality standard. The parameter index value obtained was 2.20 which was classified as lightly polluted. The water in the puddle cannot be consumed by livestock, because the water does not meet the quality standard based on the calculation of the quality status using the pollution index method.
ABSTRAKSalah satu dampak negatif dari kegiatan pembangunan adalah permasalahan lingkungan. Permasalahan lingkungan yang selalu ditemukan di sekitar kita adalah sampah. Sampah dapat dikelola dengan pendekatan 3R (reduce, reuse, recycle). Pengelolaan sampah dengan pendekatan 3R perlu disosialisasikan kepada semua pihak terutama peserta didik. Sosialisasi pengelolaan sampah dengan pendekatan 3R dilaksanakan dalam bentuk kegiatan pengabdian pada masyarakat ini berlokasi di SMPN Neonbat Kefamenanu. Tujuan pengabdian ini adalah memberi pemahaman pada peserta didik mengenai pentingnya pengelolaan sampah di lingkungan serta untuk meningkatkan pemahaman peserta didik mengenai jenis sampah organik dan anorganik. Metode kegiatan pengabdian yang digunakan adalah permainan dan pembuatan produk kreasi dari sampah. Hasil tes akhir menunjukkan bahwa terdapat peningkatan pemahaman peserta didik tentang pengelompokkan sampah organik dan anorganik. Sosialisasi pengelolaan sampah dengan pendekatan 3R pada peserta didik SMPN Neonbat telah memberi dampak positif dengan meningkatnya pemahaman mengenai pengelompokan sampah organik dan anorganik serta memberikan pemahaman kepada peserta didik bahwa sampah yang dihasilkan bisa dimanfaatkan kembali dan dapat bernilai ekonomis apabila dikembangkan menjadi sebuah produk bermanfaat. Kata kunci: sampah organik; sampah anorganik; 3R (reduce, reuse, recycle). ABSTRACTOne of the negative impacts of development activities is environmental problems. Environmental problems that are always found around us are garbage. Waste can be managed with a 3R approach (reduce, reuse, recycle). Waste management with the 3R approach needs to be socialized to all parties, especially students. The socialization of waste management with the 3R approach was carried out in the form of community service activities located at SMPN Neonbat Kefamenanu. The purpose of this service is to provide students with an understanding of the importance of waste management in the environment and to increase students' understanding of the types of organic and inorganic waste. The method of service activities used are games and the manufacture of creative products from waste. The final test results show that there is an increase in students' understanding of the grouping of organic and inorganic waste. Socialization of waste management with the 3R approach to students of SMPN Neonbat has had a positive impact by increasing understanding of the grouping of organic and inorganic waste and providing understanding to students that the waste produced can be reused and can be of economic value if it is developed into a useful product. Keywords: organic waste; inorganic waste; 3R (reduce, reuse, recycle).
Noemuti River is a river located in North Central Timor District. The river is used by local people for daily needs such as washing motorbikes and clothes. In addition, at some point it is also used to mine sand. Seeing this phenomenon, it is estimated that there has been a change in the plankton community in the river, so it is necessary to conduct research on the plankton community in the river. This research was conducted by purposive random sampling to take existing plankton samples to see their abundance, diversity, dominance and evenness using index calculations. Based on research that has been done, the Noemuti River has an abundance of plankton 11400, 8716 and 7241 cells/L. The diversity index is 2.362; 2,627; and 2,880. Dominance index 0.173; 0.121 and 0.071 and the evenness index is 0.753; 0.838 and 0.918 this shows that the Noemuti River has a moderate and relatively even distribution of plankton diversity. So it can be concluded, that activities around the Noemuti river do not really affect the existing plankton community.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
