Jeneberang watershed is one of the watersheds in the MAMMINASATA area (Maros, Makassar, Sungguminasa and Takalar). The watershed, upstream, is now in a critical condition. This study aims to identify and map land use patterns, carbon stock emissions, both in the present condition and after rehabilitation condition. The data and information used in this research are Landsat 7 ETM+ in 2006 and 2010, the Jeneberang watershed boundary map, critical land map, forest area map, rainfall data, population data, and land capability class map. The method used is the interpretation of land use or land cover, biomass calculation, and analysis with REDD ABACUS. The results showed that land use was dominated by plantations and then followed by low density forest, agricultural dry land, rice fields, water bodies, plantation forests, vacant land, shrubs, settlements, high density forests, and savannas. The direction of land cover/land use that can increase carbon sequestration is the conversion of barren land, shrubs and savannas into plantation forests and agroforestry. Potential carbon stocks for plantations, dry land agriculture and rice fields will increase to 2.295.626,32 tons in 2026.

Tanaman porang di beberapa wilayah di Kalimantan Timur memiliki potensi besar untuk dibudidayakan dengan kondisi lahan dan iklim yang mendukung. Salah satu masalah yang dihadapi petani di kota Samarinda yaitu kurangnya informasi mengenai sistem pemasaran yang efektif. Tidak semua pabrik mau menerima hasil panen karena ada standar kualitas yang diterapkan. Selain itu harga jual umbi porang yang fluktuatif, memberikan ketidakpastian dalam pemasarannya. Oleh karena itu perlu adanya rumusan mengenai strategi pemasaran porang, sehingga mampu meningkatkan kesejahteraan petani dan mengembangkan budidaya porang secara berkelanjutan yang dapat memenuhi kebutuhan manusia secara lebih baik dan berkesinambungan dengan tetap menjaga kelestarian lingkungan hidup. Penelitian ini bertujuan untuk merumuskan strategi pengembangan pemasaran porang di Kota Samarinda. Data primer dan sekunder diperoleh melalui observasi, wawancara, kuesioner, dan studi pustaka yang kemudian dianalisis menggunakan metode dan matriks IFAS, EFAS dan SWOT. Hasil penelitian menunjukkan bahwa strategi pemasaran yang ditawarkan dengan menggunakan kombinasi S-O, yakni mendukung kebijakan pertumbuhan yang strategis dimana faktor kekuatan tetap dipertahankan dengan memanfaatkan peluang yang dimiliki, meliputi: pemanfaatan lahan dalam skala kecil untuk meningkatkan produksi guna memenuhi pangsa pasar dalam dan luar negeri, bentuk komoditas yang dipasarkan bukan hanya dalam bentuk umbi tetapi juga dalam bentuk chip atau bahkan produk olahan berupa tepung glukomanan, penjalinan kerjasama dengan instansi lain seperti dengan pihak akademisi yang akan memberikan ilmu dan pengetahuan cara mengolah porang menjadi produk olahan seperti tepung dengan menggunakan alat yang ada di laboratorium.
