ABSTRAKMeningkatnya kandungan karbondioksida (CO 2 ) serta berkurangnya luas hutan sebagai penyerap CO 2 di atmosfer merupakan penyebab pemanasan global. Salah satu solusi untuk menurunkan kandungan CO 2 di atmosfer adalah melalui pembangunan atau perbaikan vegetasi hutan. Hutan mangrove dianggap dapat menyerap karbon cukup baik melalui proses fotosintesis. Tujuan penelitian ini yaitumengestimasi simpanan karbon tegakan dan seresah hutan mangrove di Desa Margasari Kecamatan Labuhan Maringgai Kabupaten Lampung Timur. Penelitian ini dilakukan dengan metode jalur berpetak. Jalur dan petak awal ditentukan secara acak kemudian jalur dan petak diambil secara sistematis. Petak pengamatan pohon dibuat berukuran 20 m x 20 m dengan jarak antar petak pada jalur 20 m dengan jumlah 20 petak. Setiap petak dilakukan pengukuran diameter pohon≥ 5 cm. Masing-masing petak dibuat sub petak pengamatan serasah berukuran 0,5 m x 0,5 m. Perhitungan jumlah biomassa tersimpan pada pohon menggunakan persamaan allometrikB = 0,1848D 2.3624 dan pada seresah menggunakan total berat kering. Konsentrasi karbon dalam bahan organik biasanya sekitar 46% sehingga mengalikan biomassa masing-masing dengan46%. Hasil penelitian diperoleh rata-rata biomassa hutan mangrove sebesar 431,78 ton/ha. Estimasi karbon tegakan mangrove 197,36 ton/ha dan estimasi karbon serasah 1,25 ton/ha, sehingga berdasarkan hasil penelitian jumlah estimasi total karbon tersimpan hutan mangrove 198,61 ton/ha.

Community forestry adoption basedon multipurpose tree species diversity towards to sustainable forest management in ICEF of University of Lampung, Indonesia.Biodiversitas 19: 1102-1109. Integrated Conservation Education Forest (ICEF) of University of Lampung (Unila) at Wan AbdulRachman (WAR) Forest Park is a conservation forest which should be free from any kinds of human activities. In fact, more than 75%the area has been managed by community hence there is a need for management strategy through Community Forestry (CF). It is knownthat there are a lot of Multipurpose Tree Species (MPTS) that can be utilized for the community’s daily life. The research’s objectivesare to analyze the ability of the community to adopt CF scheme, to calculate the diversity index of MPTS and level of Skill KnowledgeAttitude (SKA) and to determine the correlation variables to sustainable CF. This study used Shannon-Wiener diversity index, analysisof SKA level and regression analysis for adoption level. The results of this study noted that at the research site has diversity index 0.115and 74.29% of plants are MPTS. Based on the data analysis, 168 respondents [89%] agree to adopt CF scheme and level of their SKA ismoderate therefore needs to increase this level towards to forest sustainability. There are three variables of community forestry adoptiontoward to sustainable forest management at ICEF: number of trees species, the volume of forest products that would be sold, and rolesof extension education.

The Integrated Conservation Education Forest (ICEF) of Tahura Wan Abdul Rahman (Tahura WAR) with the total area about 1.143 preserved  floras and faunas habitat hold the roles as a nature conservation area with main purposes as education, research, cultivation, culture, tourism, and  recreation activities. ICEF of Tahura WAR devided by many blocks preservation block which used as protect the plants and faunas, in addition the affect of exploitation activity and utilization or social forestry block which used as community forest models that managed by people which have the structure and composition of vegetation. The research was conducted from November to December 2015 in utilization block of Tahura WAR with the purpose to identified the composition, structure, and vegetation diversity. The method used  in the research was survey, and the methods of sampling was random sampling about 19 plots. The result of the study showed there were 728 species of plants consisted by 275 species of under plants, 97 species of seedlings, 137 species of saplings, 76 species of poles and 143 species of trees.Key words: composition, structure, great forest park Wan Abdul Rachman

ABSTRAKIndonesia memiliki areal lahan basah yang cukup luas, 21% dari luas daratannya adalah lahan basah dengan luasan lebih dari 38 juta hektar. Desa Kibang Pacing Kecamatan Menggala Timur merupakan salah satu lahan basah di Provinsi Lampung yang memiliki kekayaan jenis burung sejumlah 40 spesies dari 21 famili (Triyanah, 2014). Kekayaan jenis burung tersebut perlu dilakukan inventarisasi kembali dengan melakukan penelitian lanjutan untuk mengetahui jenis burung yang potensial dijadikan objek wisata pengamatan burung (birdwatching) dilihat dari status konservasi dan status ekologinya. Penelitian ini bertujuan untuk mengetahui jenis burung yang potensial dijadikan objek wisata birdwatching dan membandingkan dengan penelitian sebelumnya yang dilakukan oleh Triyanah pada tahun 2014, mengetahui pengaruh kondisi habitat dan tipe vegetasi terhadap keberadaan dan aktivitas burung, serta mengetahui persepsi masyarakat mengenai wisata birdwatching. Metode yang digunakan dalam penelitian ini adalah metode point count, rapid assessment, dan wawancara semiterstruktur. Analisis data dilakukan melalui analisis deskriptif. Hasil penelitian ditemukan 27 jenis burung yang masuk dalam kategori endemik dan hanya 13 jenis burung yang masuk dalam kategori dilindungi. Kondisi habitat dan tipe vegetasi sangat berpengaruh terhadap keberadaan dan aktivitas burung. Keberadaan burung paling banyak ditemukan pada tipe vegetasi gelam yang kondisi habitatnya baik dengan sumber pakan yang melimpah sehingga aktivitas burung ditemukan paling banyak mencari makan. Masyarakat mendukung sepenuhnya untuk pengembangan wisata birdwatching di Desa Kibang Pacing. Penelitian ini diharapkan dapat menjadi dasar pengembangan wisata birdwatching di Desa Kibang Pacing. (Triyanah, 2014). Further research was needed to determine the potential bird species that will be used as attraction bird (birdwatching) in terms of its conservation status

This article argues that the practice of agroforestry provides ecological contributions to the smallholder farmers cultivating in the watershed areas. Specifically, this farming system provides contribution to carbon sequestration potential of the woody perennials and the biodiversity conservation of the other components of the system. This argument is based on the research conducted in Molawin-Dampalit Sub-Watershed, Mt. Makiling Forest Reserve in the Philippines and Way Betung Watershed in Indonesia. The research involved an interview session of 106 and 261 smallholder farmers and an assessment of 27 and 14 agroforesty plots for carbon stock assessment and biodiversity assessment, respectively. Results indicated that the total carbon found among the crop components was 52.32 MgC/ha in Molawin-Dampalit Sub-Watershed and 244.26 MgC/ha in Way Betung Watershed, which suggested the high carbon sequestration potential of the woody perennials and understory crops in an agroforestry system. The farm lots being cultivated by the smallholder farmers were found to contribute to biodiversity conservation having a moderate biodiversity index of 2.59 and 2.53, respectively. With these findings, promotion of desired agroforestry systems in suitable portions of the watershed areas should be intensified and heightened to contribute to ecological balance across the landscape. Agroforestry should always be an integral part of all initiatives toward ecological restoration with the cultivators/smallholder farmers as potential partners. The agroforestry system should consider all the technical and socioeconomic considerations toward having diverse components and ensure food security among the smallholder farmers throughout the year.
