Tenurial Conflicts Within Protected Forest Management Unit (PFMU) of Tarakan, North Kalimantan Rositah, Erna; Sardjono, Mustofa; Aipassa, Marlon; Suyadi, Suyadi; Obeth, Ernita This research aims to discuss the forms, actors involved, causes, and alternative solutions in regards to tenurial conflicts occurring within the protected forest management unit of Tarakan. We used a qualitative approach using in depth interviews, observation, and taking field notes. Participants of the study were selected using purposive and snowball sampling. The conflicts are aroused when indigenous communities claim that the forests belong to them. Others include local entrepreneurs who encroach and occupy forestland for settlement, agriculture, and farming. Many cases showed that members of local communities buy and sell forest land. The leading causes of conflicts include unclear boundaries of forests, poor law enforcement, the dualism of forest authority, and ego sectoral of government agencies. To resolve the conflicts, we empowerment of communities through forestry partnership, law enforcement, strengthening of agencies both for the Protected Forest Management Unit (PFMU) of Tarakan and the Community to support the implementation of forestry partnership

LAJU RESAPAN AIR PADA FORMASI TANAH BERBEDA DI SUB DAS KARANG ASAM BESAR KOTA SAMARINDA Sarminah, Sri Resapan air merupakan proses masuknya air hujan ke dalam tanah sebagai akibat adanya gaya kapiler dan gaya gravitasi dengan cara infiltrasi dan permeabilitas ke lapisan tanah yang lebih dalam. Sub-DAS Karangasam Besar memiliki empat formasi tanah dominan yaitu (Endoaquaepts), (Eutrudepts), (Hapludults) (Pemukiman). Penelitian dilakukan ini untuk menduga besaran laju infiltrasi dan permeabilitas pada keempat formasi tanah tersebut. Pada penelitian ini dilakukan pengamatan model infiltrasi menggunakan alat double ring infitrometer serta analisis permeabilitas pada masing-masing formasi tanah. Laju infiltrasi tertinggi pertama adalah pada formasi tanah pemukiman sampel 1 sebesar 3, 251 tertinggi kedua pada formasi tanah pemukiman sampel 2 sebesar 2, 614 laju infiltrasi tertinggi ketiga pada formasi tanah PH-KD sampel 2 sebesar 2, 395 hingga laju infiltrasi paling rendah terdapat pada formasi tanah KD-PH sampel 2 sebesar 1, 281 tergolong dalam kelas lambat. Permeabilitas tertinggi pertama pada formasi tanah PH-PK sampel 1 sebesar 5,65 cm/jam masuk kedalam kelas sedang sampai lambat, permeabilitas tertinggi kedua pada formasi tanah PH-KD sampel 1 sebesar 5, 34 cm/jam masuk kedalam kelas sedang sampai lambat, permeabilitas tertinggi ketiga pada formasi tanah PH-KD sampel 2 sebesar 3,66 cm/jam masuk kedalam kelas sedang sampai lambat, hingga permeabilitas paling rendah pada formasi tanah PH-KE sampel 2 0,46 cm/jam masuk kedalam kelas sedang sampai lambat. Hasil perbandingan hubungan karakteristik fisik tanah dengan laju infiltrasi dan permeabilitas tanah yaitu rata-rata setiap satuan jenis tanah memiliki tekstur halus dengan kandungan liat yang tinggi memiliki pengaruh signifikan terhadap laju infiltrasi dan permeabilitas.; Resapan air merupakan proses masuknya air hujan ke dalam tanah sebagai akibat adanya gaya kapiler dan gaya gravitasi dengan cara infiltrasi dan permeabilitas ke lapisan tanah yang lebih dalam.

PENDUGAAN EROSI TANAH PADA TIGA TUTUPAN VEGETETASI BERBEDA DI KELURAHAN LEMPAKE KOTA SAMARINDA Sarminah, Sri; Karyati, Karyati The rapid growth of the population resulted in an increase in the needs of life both in quantity and quality, while the availability of land resources decreased and was very limited. Conflicting situations increase pressure on land resources that are forced to produce as high as possible causing land damage including erosion. This study aims to estimate the erosion rate and establish erosion hazard level (TBE) status on three land covers (secondary forest, shrubland, open land). The time of this study was carried out for seven months effective, starting from December 2021 to June 2022. The method used in this study is the stick method with a length of 1 m and a plot measuring 20 m × 15 m as many as 3 plots, namely a measurement plot in a secondary forest, shrubs and open land as well as soil sampling for soil physical and chemical properties. The results showed that the highest erosion rate value in Lempake Village, Samarinda City occurred in open land, which was 1862,60 tons ha -1 year -1 , and shrubs of 765,040 tons Ha -1 year -1 , included in class V (very heavy), while the lowest erosion rate value occurred in secondary forests, namely 74,80 tons ha -1 year, including in class III (currently). In connection with controlling the erosion rate, it is recommended to apply vegetative methods such as planting legume cover crop soil cover vegetation and enrichment of fast growing species.

Water infiltration rate of illegal mining sites in Bukit Soeharto Forest Park, East Kalimantan Province Sarminah, Sri; Rafi, Muhammad Infiltration is a component of the hydrological cycle which functions as a source of groundwater, minimizing flooding and distributing water evenly throughout the rainy and dry seasons. This study aims to determine the rate of water infiltration or infiltration and permeability values in 2 (two) land conditions for ex-illegal mining sites, namely at KM 68 and KM 48, and the location of undisturbed land in KM 54 secondary forest area of the Bukit Soeharto Forest Park (BSFP). The research method used a double ring infiltrometer, then tested at the Kalimantan Bioresources Laboratory. Infiltration rate shows that secondary forest area of the KM 54 location was 275.2 mm/hour which was included in the very fast class, while in the former mining sites KM 68 and KM 48 respectively it was 244.6 mm/hour, and 145.7 mm/hour which is included in the fast class. Laboratory analysis shows that the soil permeability value in the secondary forest area of KM 54 location was 6.41 cm/hour which was included in the rather fast class, while the permeability value in the ex-mining land area of KM 68 and KM 48 respectively was 6. 26 cm/hour and 3.66 cm/hour which are included in the medium class. This is due to the physical soil properties such as soil texture, soil structure, bulk density, and soil porosity which are the factors that cause differences in infiltration rates in several land conditions.
