Abstract

Vegetation is one factor that can decrease carbon accumulation in the atmosphere. The diversity of plant species in each land use has different abilities to absorb carbon in the atmosphere. This research was conducted in Pesisir Barat Regency of Lampung Province on 4 (four) types of land use, namely: (1) natural forest in Balai Kencana Resort, Bukit Barisan National Park (2) oil palm plantation in Pekon Marang, (3) coffee plantation in Pekon Suka Mulya, and (4) agroforestry of repong damar in Pekon Pahmungan. This reserach aims to analyze the diversity of plant species and to calculate the potential of plant carbon stock and carbon sequestration (above ground biomass) using alometric equations in various types of land use in Pesisir Barat Regency. The research method was vegetation analysis to learn about the diversity of plant species and calculation of carbon stock using alometric equations. The results showed that the composition of plant species in Bukit Barisan NP found 83 plant species belonging to 37 families, in the palm plantation found 9 plant species belonging to 8 families, in the coffee garden found 17 plant species belonging to 11 families, and in agroforestry of repong damar found 73 plant species belonging to 33 families. The total carbon stock potential was 376.16 ton/ha and carbon sequestrated. 1 257.20 ton/ha with the highest carbon uptake available at repong damar agroforestry site of 901.11 ton/ha.Keywords: aboveground biomass, carbon, diversity, pesisir barat regency

Abstract

Penelitian ini mengkaji kelayakan finansial dan dampak dari model pengelolaan ternak yang ditemukan di sekitar hutan Gunung Mutis di Pulau Timor. Data dikumpulkan melalui wawancara terhadap 40 masyarakat sekitar hutan. Terdapat dua model pengelolaan ternak yang ditemukan di sekitar hutan. Model pertama adalah model pemeliharaan ternak di dalam kandang dan model kedua adalah model penggembalaan ternak di hutan. Hasil penelitian menunjukkan bahwa kedua model layak secara finansial. Namun demikian, jika menggunakan biaya tenaga kerja komersial, model pemeliharaan ternak di dalam kandang secara finansial tidak layak untuk dilakukan, sedangkan model penggembalaan di hutan layak secara finansial. Model pengelolaan ternak di dalam hutan berdampak negatif terhadap regenerasi pohon sedangkan model pemeliharaan ternak di dalam kandang tidak berdampak negatif terhadap kelestarian hutan. Dari hasil penelitian disarankan agar pemerintah membatasi areal untuk penggembalaan ternak di hutan.Kata kunci: kelayakan finansial; model silvopasture; Mutis; penggembalaan ternak hutan; Timor Livestock Management Models Around Mt. Mutis Forest and Its Impact on Forest SustainabilityAbstractThe study examined the financial feasibility and impacts of livestock management models found around Mt. Mutis forest in Timor Island of Indonesia. Data was collected through interviewing 40 communities around the forest. There were two livestock management models around the forest, the first model was livestock management which raise livestock in the cattle pen, and the second model was livestock management which graze livestock in the forest. This study found that both livestock management models were financially feasible. However, if commercial cost of workers was counted, the livestock management model which raise livestock in the cattle pen was financially not feasible while livestock management model which graze livestock in the forest was financially feasible. Livestock management model which graze livestock in the forest however had negative impacts on the regeneration of trees. On the basis of this study, it is suggested that the government should limit the forest area that could be used for forest grazing.

Abstract

Development of protected forest is often considered to be a way to preserve biodiversity and ecosystem service.  To keep protected area, Indonesia government excludinged local people from protected forest by making a policy which prohibits grazing on protected forest. However, the success of protected forest management often depends on the perception of local people because the policy has affected livestock owners who have an interest in forest use. Exclusion of local people from protected forest leads loss of people income and unemployment. This study applied a socioeconomic approach to examine and analyze the livestock owner perception on forest grazing prohibition in Timor Island of Indonesia by conducting a household survey of 36 livestock owners. The study results showed that 30.6%, 50.0%, 19.4%, 0%, and 0% of livestock owners are totally disagree, disagree, neutral, agree, and totally agree, with grazing prohibition, respectively. In addition, people perception was significantly affected by the number of livestock owned by people. It means that livestock owners mostly reject the policy on grazing prohibition. Indeed policy which prohibits grazing on the protected forest is not effective to be implemented. Government and policy maker should review the policy and consider the refusal of livestock owner toward exclusion policy. The interest of local people should be considered in developing a policy on protected forest.

Abstract

Tujuan penelitian adalah menganalisis respon para pemangku kepentingan di daerah terhadap kebijakan Hutan Tanaman Rakyat. Penelitian menggunakan metode pendekatan kuantifikasi data kualitatif. Lokasi penelitian ditentukan secara sengaja dengan pertimbangan tingginya potensi pengembangan kegiatan HTR, yaitu di Provinsi Kalimantan Selatan dan Riau. Hasil penelitian menunjukkan bahwa masyarakat di Kalimantan Selatan, khususnya mereka yang telah terlibat dalam pengembangan tanaman kehutanan memiliki minat yang tinggi untuk menjadi peserta program HTR. Sedangkan masyarakat di Riau kurang berminat terhadap program penanaman tanaman kehutanan, disebabkan adanya pengalaman buruk di masa sebelumnya. Para pemangku kepentingan di tingkat kabupaten yang terdiri dari pihak pemerintah daerah dan swasta menyambut baik program tersebut, dan mendukung terselenggaranya program sebagai upaya peningkatan kesejahteraan masyarakat sekitar hutan. Berdasarkan hasil analisis stakeholder diketahui bahwa terdapat sejumlah pemangku kepentingan di daerah yang memiliki posisi dan pengaruh penting untuk keberhasilan program. Hal ini berimplikasi bahwa para pengambil kebijakan di tingkat pusat harus mempertimbangkan aspirasi mereka untuk mewujudkan keberhasilan program HTR.

Abstract

Hutan Tanaman Rakyat (HTR) merupakan kebijakan Pemerintah Indonesia yang membutuhkan partisipasi dan tanggungjawab dari masyarakat lokal untuk mengelola hutan produksi secara berkelanjutan. Penelitian terhadap kapasitas masyarakat sebagai pemeran utama dalam kebijakan ini sangat dibutuhkan. Tujuan dari penelitian adalah: (1) mengukur modal fisik, modal manusia dan modal sosial yang dimiliki oleh masyarakat dan mengidentifikasi tingkat partisipasi masyarakat dalam program HTR; (2) menganalisis hubungan antara modal fisik dan modal manusia terhadap elemen dari modal sosial dan antara modal sosial dengan tingkat partisipasi masyarakat; dan (3) membangun strategi implementasi kebijakan HTR. Data akan dianalisis dengan menggunakan analisis deskriptif, korelasi peringkat Spearman, SWOT dan QSPM. Informasi yang digunakan dalam penelitian ini berasal dari hasil survey terhadap 81 kepala keluarga dari Desa Taman Bandung, Seko Besar dan Lamban Sigatal di Kabupaten Sarolangun. Hasil penelitian menunjukkan bahwa modal fisik, modal manusia dan modal sosial dalam katagori sedang. Tidak ada korelasi antara modal fisik dan modal sosial, namun terdapat korelasi antara modal sosial dengan modal manusia. Strategi terpilih dalam mengimplementasikan kebijakan HTR adalah: (1) Mengakomodir pola pemanfaatan kawasan hutan yang ada saat ini sebagai motivasi masyarakat untuk berpatisipasi dalam kebijakan HTR; (2) Mengotimalkan dukungan pemerintah daerah dalam percepatan implementasi melalui pendampingan dan sosialisasi secara intensif; dan (3) Menggunakan isu kelangkaan kayu dan peluang pemasaran ke PT Samhutani sebagai rangsangan bagi masyarakat untuk menanam tanaman berkayu.

Abstract

Ministry of Environment and Forestry launched a flood prevention program in Garut regency with 3 rehabilitation programs namely conventional tree planting (Conventional Crops), Air Nurseries, and agroforestry forests. Choice of type is the key to success of agroforestry. The most widely planted species in the Cimanuk watershed are cultivars combined with vegetable crops. This study aims to analyze the soil chemical fertility status on eucalyptus-based vegetable agroforestry patterns in some age classes and to analyze changes in soil fertility status after harvest. The soil fertility status is chemically classified in all plots either monoculture or under eucalyptus age 2, 4, and 6 years.. Agroforestry planting patterns can improve the soil fertility status chemically into high categories. Prior to cultivation the mean value of CEC was 24.72 me / 100gr (moderate), Saturation Base 64.19% (high), P2O5 35.57 me / 100gr (very high), K2O 213.48 me / 100gr (very high), and C-org 3.54 % (high). After harvest the average value of CEC is 25.36 me/100g (high), Saturation Base 66.04 % (high), P2O5 77.05 me/100g (very high), K2O 652.83 me/100g (very high), and C-org 3.84 % (high).Key words: agroforestry, Cimanuk watershed, vegetable

Abstract

Candlenut tree is one of the multipurpose tree   species because almost all parts of the plant can be utilized. The candlenut trees grow and are distributed  in all provinces of Indonesia. Tanah Pinem in Dairi Regency is one of the candlenut-producer area. The objectives of this study were to learn and describe the management of candlenut  tree in Tanah Pinem Subdistrict. The research was conducted with survey method by collecting data in the field. Primary data  were   obtained through structured interviews, while secondary data were obtained from relevant institutions and previous researches. The data were analyzed and described to learn how the community manage the candlenut tree and the condition at that time. The results showed that the candlenut tree is one of the plants that are beneficial because it can be a source of income for the community and play a role in safeguarding the environmental conditions of Tanah Pinem subdistrict. However, the management of candlenut tree was not intensive. Area size and production of candlenut tree tended to decrease each year. About 90% of Tanah Pinem subdistrict topography are steep and very steep, and it is necessary to replant the land with trees such as candlenut to protect the land from erosion and landslide hazards.
