ABSTRACTThe aimed of this research is to know of mammals composition in dipterocarpa lowland forest, Batu Berok Protection Forest (BBPF), Long Pahangai, East Kalimantan. Combination method was done in this research, there is camera trapping survey, captured, direct and un-direct inventory by line transects and interview with local people. I have used 10 set of camera trapping, 50 cage traps, and 3.5 km line transect.Total 32 species of mammals were detected in this area, comprising 8 ordo (Scandentia, Dermoptera, Chiroptera, Primates, Pholidota, Rodentia, Carnivora and Artiodactyla) and 19 family (Tupaiidae, Cynocephalidae, Pteropedidae, Tarsiidae, Cercopithecidae, Hylobatidae, Manidae, Sciuridae-Sciurinae, Sciuridae-Petauristinae, Muridae, Hystricidae, Ursidae, Mustilidae, Viverridae, Felidae, Suidae, Tragulidae, Cervidae, and Bovidae) including Sun bear Helarctos malayanus, Sambar deer Rusa unicolor, Banded Palm Civet Hemigalus derbyanus, Clouded Leopard Neofelis diardi, and Tarsius Tarsius bancanus. The composition of mammals illustrates a pyramid pattern in the food chain which mean is very feasible for the habitat of mammals. Genus and Family Index illustrate the diversity of mammal in the study area 54% of mammals’ species in East Kalimantan and 56% of mammals’ species in Borneo. By IUCN redlist, 4 species included as endangered species and 8 species as vulnerable, 16 species included in appendix of CITES and 10 species included in the Indonesian government regulation (PP. 7/1999) as protected species.The diversity of mammal in BBPF by quick survey was relatively hight, but as a protected forest this area was not good managed whereas located in the central of heart of Borneo. Intervention by government program is deeply needed.Key word: camera trapping, cage trap, food chain, IUCN ABSTRAKTujuan penelitian ini adalah untuk mengetahui komposisi mamalia di hutan dipterokarpa dataran rendah, Hutan Lindung Batu Berok (HLBB), Long Pahangai, Kalimantan Timur. Kombinasi metoda telah dilakukan pada penelitian ini, yaitu kamera otomatis, penangkapan, pengamatan langsung dan tidak langsung dengan transek, serta wawancara dengan masyarakat lokal. Digunakan 10 kamera otomatis, 50 perangkap mamalia kecil dan 3.5 km transek.Total 32 species mamalia telah terdeteksi di kawasan ini termasuk ke dalam 8 ordo (Scandentia, Dermoptera, Chiroptera, Primates, Pholidota, Rodentia, Carnivora and Artiodactyla) dan 19 famili (Tupaiidae, Cynocephalidae, Pteropedidae, Tarsiidae, Cercopithecidae, Hylobatidae, Manidae, Sciuridae-Sciurinae, Sciuridae-Petauristinae, Muridae, Hystricidae, Ursidae, Mustilidae, Viverridae, Felidae, Suidae, Tragulidae, Cervidae, and Bovidae), termasuk Beruang Madu (Helarctos malayanus), Rusa (Rusa unicolor), Musang Belang (Hemigalus derbyanus), Macan Dahan (Neofelis diardi), and Krabuku Ingkat (Tarsius bancanus) mamalia yang ditemukan menggambarkan pola piramida dalam rantai makanan, yang berarti bahwa kawasan ini sangat layak untuk habitat mamalia.

Salah satu komponen dari ekosistem hutan hujan tropis adalah tumbuhan bawah. Tumbuhnya secara alami tumbuhan bawah di lahan pasca tambang batubara akan membantu dalam proses memulihkan lahan hutan yang terganggu. Penelitian ini bertujuan untuk mengetahui kondisi tumbuhan bawah dan jenis pionir alami di lahan pasca tambang batubara dalam hal kekayaan jenis, keragaman jenis. Pengumpulan data dilakukan dengan menggunakan metode garis berpetak di lahan revegetasi. Hasil inventarisasi diluar lahan revegetasi dijumpai 71 jenis tumbuhan bawah, sedangkan di lahan revegetasi dijumpai 43 jenis tumbuhan bawah. Dari kedua lokasi penelitian, jenis tumbuhan bawah di lahan sekeliling lokasi penelitian dijumpai lebih banyak. Jika dibandingkan dengan data rona awal, jenis tumbuhan bawah lebih beragam pada saat penelitian dilakukan. Kondisi tersebut diduga karena tempat penelitian sebelum dilakukan penambangan merupakan hutan sekunder bekas hutan produksi yaitu Hutan Produksi Terbatas (HPT) dan Hutan Tanaman Industri (HTI). Di lahan revegetasi terdapat 4 jenis tumbuhan pionir yaitu Homalanthus populneus (Geiseler) Pax., Macaranga gigantea (Rchb.f. & Zoll.) Muell.Arg.,Macaranga tanarius (L.) Muell.Arg., dan Trema orientalis L. (Blume). Lahan pasca tambang batubara merupakan lahan yang mengalami gangguan berat, serta merupakan komunitas yang terkendali oleh manusia, sehingga memiliki keragaman jenis yang rendah.

Ketepeng (Cassia alata L.) was a group of plants included in the Magnoliophyta division which can be found in tropical or subtropical areas. The purpose of this study was to determine the potential of Ketepeng leaves to inhibit the growth of R. solanacearum and S. sobrinus bacteria. The method used in this study is agar well diffusion with 3 replications. The sample used was Ketepeng leaf extract with several concentrations of 0.5%, 1%, 2%. Positive controls in this study were Chloramphenicol and negative control of 40% ethanol. The variables calculated are the calculation of water content, percentage of yield and percentage of area diameter barriers (DDH). In addition, the DDH results show the ethanol extract of Ketepeng leaves at concentrations of 0.5% and 1% not able to inhibit the growth of R. solanacearum, but at a concentration of 2% able to inhibit R.solanacearum with a diameter of 11,7 mm and the ethanol extract of Ketepeng leaves at concentrations was able to inhibit the growth of S. sobrinus bacteria with the highest diameter of 16 mm at a concentration of 2%.

Universitas Mulawarman dengan pola ilmiah pokoknya hutan tropis lembab dan lingkungannya, memiliki salah satu laboratorium alam berupa Hutan Pendidikan Fakultas Kehutanan Unmul (HPFU). Areal ini menjadi menarik karena HPFU disamping representasi hutan alam tropis yang relatif cukup bagus juga posisinya yang sangat strategis . HPFU mengalami dinamika baik kondisi biogeofisik karena faktor alam khususnya kebakaran hutan tahun 1982/1983, 1992/1993, dan 1997/1998, maupun akibat aktivitas manusia.Hasil penafsiran citra Landsat liputan 2016 seluas 299,03 Ha, penutupan lahannya didominasi hutan sekunder seluas 204,13 Ha (68,99%) dan belukar 67,97 Ha (22,97%). Hasil inventarisasi hutan tahun 2016 dijumpai sebanyak 73 jenis pohon. Potensi rata-rata strata belukar 127,81 m3/Ha dengan 130 batang/Ha dan hutan sekunder 135,46 m3/Ha dengan 111 batang/Ha. Pendugaan cadangan karbon pada areal HPFU sebesar 32.937,79 ton. Sementara itu keberadaan satwa diantaranya Orang Utan (Pongo pigmaeus), Owa-Owa (Hylobates muelleri), berbagai jenis burung seperti Rajawali (Thearaetus pennatus), Elang bondol, Ular Phyton, Kura-kura, dan lain-lain.Selain dinamika biogeofisik dan sosial budaya masyarakat sekitar HPFU, status penetapan kawasan hutan juga mengalami perubahan seiring berjalannya waktu mulai dari ex areal HPH CV Kayu Mahakam, berturut-turut menjadi Hutan Koleksi Universitas Mulawarman, Hutan Pendidikan Fakultas Kehutanan Unmul, Kebun Raya Unmul, Kebun Raya Unmul Samarinda, dan kini berdasarkan SK Menhut No.674/Menhut-II/2011 menjadi KPHP Samarinda yang penamaannya akan diusulkan menjadi KPHP Hutan Pendidikan Fakultas Kehutanan Universitas Mulawarman (HPFU) bersamaan dengan pembuatan dokumen tata hutan dan RPHJP pada tahun 2017 ini.Dengan ditetapkannya HPFU sebagai KPHP, maka potensi biogeofisik dan sosial budaya masyarakat sekitar hutan akan menjadi potensi harapan yang besar meskipun di sisi lain ada beberapa kendala dan permasalahan yang dihadapi yaitu : struktur kelembagaan yang ada (perlu adanya sinkroniosasi antara Fahutan Unmul, Badan Pengelola Hutan Pendidikan Fahutan Unmul, dan Dishut Propinsi Kaltim tentang KPHP Samarinda ; aktivitas tambang batubara yang berbatasan langsung dengan kawasan KPHP Samarinda; kerawanan terhadap kebakaran hutan; keterbatasan investasi dan kondisi sarana dan prasarana yang sudah mulai rusak. Adapun peluang dan pengembangan KPHP Samarinda adalah diupayakan sebagai KPH center khususnya di Kaltim dan Kalimantan umumnya, pembangunan model-model pengelolaan hutan serta pembangunan ekowisata modern.

High economic value encourages the hunt for agarwood in nature to increase and not be controlled so that the existence of agarwood becomes threatened and rare. Gyrinops versteegii (Gilg.) Domke is one example of agarwood-producing plants that are native to Indonesia and have different characteristics from other types so that it is preferred by consumers. Exploration and study of Gyrinops is very necessary, because information about Gyrinops is still very limited, especially to find out the population and its presence in nature and which has been cultivated by the community. The study of G. versteegii population was conducted in 7 locations in four districts namely West Lombok, North Lombok, East Lombok and Central Lombok conducted on 16-29 April 2018. There were 210 G. versteegii individuals found with 20 individual seedling growth stages, 54 individual saplings 98 individual poles and 38 individual trees. The location of the meeting is marked by its geographical location with the Global Positioning System (GPS). G. versteegii can be found in various environmental parameters, namely altitude 99 - 925 masl; slope 0 - 36.6 °; soil pH 5.5 - 6.6; soil moisture 50 - 95%; Light intensity 212 -> 20,000 Lux; air temperature 26.4 - 32.5 ° C and relative humidity 66.5 - 90%. G. versteegii that grows naturally can only be found at the Aikmel Resort in the Mount Rinjani National Park (TNGR) and there are only two individuals. Further exploration needs to be carried out in the area to determine the amount and conservation steps of G. versteegii remaining on the Island of Lombok.
