Penelitian ini bertujuan untuk mengetahui karakteristik stomata pada beberapa jenis pohon disekitar area kampus Universitas Timor. Penelitian dilaksanakan di Laboratorium Pendidikan Biologi Universitas Timor. Data yang diperoleh dianalisis secara deskriptif yaitu dengan mengamati stomata yang ditemukan pada daun, dan melakukan dokumentasi berupa foto. Pada pengamatan di lapangan 13 jenis tumbuhan ditemukan 4 tipe stomata yaitu parasitik seperti pada Filicium decipiens pada luas pengamatan 0,1372 mm2, anomositik pada Cocos nucifera pada luas pengamatan 0,0633 mm2, anisositik pada Gliricidia sepium pada luas pengamatan 0,1372 mm2, stomata aktinositik Anacardium occidentale dan Citrus aurantiifolia pada luas pengamatan 0,1372 mm2. Santalum album menampakkan jumlah stomata yang paling banyak yaitu 105 stomata, Dracaena fragrans hanya menampakkan 4 stomata. Cocos nucifera  memiliki stomata dengan panjang (28.7 µm) dan lebar stomata (13.4 µm) yang lebih besar bila dibandingkan dengan stomata tumbuhan lainnya seperti Citrus aurantiifolia dengan Panjang (6.3 µm) dan lebar (5.05 µm).

Background: This research is a pilot project of plant diversity, especially the pitcher plant species (Nepenthes sp) at Palangka Raya University. The study aimed at identifying the pitcher plants (Nepenthes sp.) at Palangka Raya University. In August-November 2020 conducted this research.Methods: Data on the diversity of pitcher plants were collected using the exploring method. Data analysis used a literature study to identified using the identification book of pitcher plants. Results: The study results found three pitcher plant species in the forest on the campus of Palangka Raya University. The pitcher plants are Nepenthes mirabilis (Lour.) Druce, Nepenthes gracilis Korth., and Nepenthes rafflesiana Jack. Conclusions: The range of environmental parameter values ​​is air temperature 28-380C, medium-open coverage, 62-98% humidity, and soil pH of 5-7.5.

A large number of forests at Munggu Village, Ngabang District, Landak Regency have been converted into oil palm and rubber plantations. As consequences, natural habitats in the region have been fragmented and species diversity, including herpetofauna, has been decreased. This study aimed to assess herpetofauna diversity in four different habitats in Munggu Village: (1) forests, (2) Landak river, (3) tourist areas, and (4) rubber plantations. Data collection used Visual Encounter Survey (VES) for 8 days.[u1]  The results showed that the total of 24 herpetofauna species: 15 amphibians’ species (4 families) and 9 reptiles species (6 families) have been recorded from the four sampled areas. Of the four locations 11 species were found in river habitat in the forest, 4 species in the location of Landak river, 8 species in tourism sites and 9 species in rubber plantations. The Shannon-Wiener (H') diversity index in all four habitats was classified as moderate. In the river location in the forest, H' was 2.14, in the Landak river it was 1.28, in the tourism sites it was 1.71 and in the rubber plantation it was 1.87. However, the evenness index (E) for the herpetofauna community in all four locations was >0.80. Habitat loss and habitat destruction are among the causes of decline in amphibian and reptile populations. Knowing the diversity of herpetofauna, it is hoped that the community and stakeholders can collaborate to secure the herpetofauna in Munggu Village.

Kegiatan pengabdian ini bertujuan untuk meningkatkan pemahaman dan kemampuan guru-guru fisika di Kabupaten Hulu Sungai Tengah tentang penyusunan proposal Penelitian Tindakan Kelas (PTK). Peserta yang terlibat dalam kegiatan pengabdin ini merupakan anggota Musyawarah Guru Mata Pelajaran (MGMP) fisika Kabupaten Hulu Sungai Tengah. Tahapan yang dilakukan pada pengabdian ini terdiri atas dua tahap, yaitu penyampaian materi dan praktik penyusunan proposal PTK. Materi yang disampaikan adalah konsep dasar PTK dan analisis masalah pembelajaran, metodologi PTK, menganalisis data dan interpretasi hasil, dan merancang proposal PTK dengan metode ceramah. Hasil pengabdian ini adalah bertambahnya pemahaman dan kemampuan guru tentang penyusunan proposal PTK. Hasil kegiatan pengabdian ini dapat dijadkan sebagai bahan masukan guru untuk meningkatkan kompetensi profesionalisme guru dengan melakukan PTK. This service activity aims to improve the understanding and ability of physics teachers in the Hulu Sungai Tengah Regency regarding the preparation of Classroom Action Research (CAR) proposals. Participants involved in this community service activity were members of the Physics Teachers Meeting (MGMP) physics at Hulu Sungai Tengah Regency. The stages carried out in this service consist of two steps, namely the delivery of material and the practice of preparing a CAR proposal. The material presented is the basic concept of CAR and analysis of learning problems, CAR methodology, analyzing data and interpretation of results, and designing CAR proposals using the lecture method. The result of this dedication is the increasing understanding and ability of teachers regarding the preparation of PTK proposals. The results of these community service activities can be used as teacher input to improve teacher professional competence by conducting CAR.
