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
This study aims to know: (1) learning resources used in the learning of terrestrial ecosystem biology material in SMAN Insana Barat School, and (2) learning resources used in the learning of terrestrial ecosystem biology material at St. Augustine School Kefamenanu. This research is a type of survey research. The study population was biology teachers at SMAN Insana Barat School and St. Augustine School Kefamenanu. This research was conducted in January-March 2019. Data collection techniques used questionnaires on land ecosystem learning resources. Data analysis techniques used qualitative descriptive statistics. The results of the study show that: (1) the learning resources used in learning Biology on terrestrial ecosystems in SMAN Insana Barat School consist of direct objects, most of which are artificial ecosystems while indirect objects are mostly presented in textbooks, textbooks, and print modules. For learning resources in the form of E-modules and the internet and other learning resources, they have not been used by SMAN Insana Barat. This is because the availability of wifi in schools is inadequate. (2) Learning resources used in learning biology of terrestrial ecosystems at St. Augustine School Kefamenanu.consists of direct objects which are mostly in the form of artificial ecosystems while indirect objects are mostly presented in textbooks, textbooks, and printed modules. For learning resources in the form of E-modules and internet as well as other learning resources, it has not been used by the teachers and student from SMAN Insana Barat School and St. Augustine School Kefamenanu East Nusa Tenggara. This is because the availability of wifi in schools is inadequate.
This research aims to determine the effect of the learning model cooperative type group investigation on students' learning motivation on ecosystem material at SMPN Kiupunu. This study is an experimental study and the design in this study is Non-Randomized Post-Test Only Control Group Design. The population in this study was all students of class VII SMPN Kiupunu totaling 36 students and the samples were taken from class VII A and class VII B, each each class is 18. The sampling technique is purposive sampling. The data collection method used is a motivational questionnaire. Based on data from research conducted at SMPN Kiupunu, it shows that there is an effect of applying the group investigation model on the learning motivation of class VII students. This is evidenced by the value of the significance level on the T-test of 0.000. This is where Ho is rejected and Ha is accepted or there is an effect of the application of the group investigation cooperative learning model on the learning motivation of class VII students.
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).
