Indonesia and Philippines are homes of biodiversity in Southeast Asia. In recent years, however, there has been a decline in biodiversity brought about by land use change. This condition poses threat on the food security of communities around the watersheds. The type and volume of main food items depend on the ecological and physiological conditions of the watersheds, in this case, Way Betung and Molawin Dampalit. When edible food is sufficient and available in an area, there is higher livelihood that the communities are food secured. This paper argues based on research which has been conducted in May to November 2015 that the food security of communities in the selected agroforestry landscapes in Way Betung and Molawin Dampalit have moderate. Levels of its food security based on four dimensions, namely: food availability, food accessibility, food stability and food utilization. Amounted 261 Indonesia farmer’s respondents and 106 Philippine’s respondents mentioned that the farm households generally practice agroforestry where the production of short-term and medium-term agricultural crops, woody perennials and livestock are deliberately combined. The type of crops grown by the farm households contribute to the level of food security.

Biomass waste that has not been utilized properly is wood waste from Sengon (Falcataria moluccana). There is a high potential for these wastes to be used as solid fuel. The quality can be further improved by converting them into charcoal briquettes. This study aimed to determine the effects of adhesive content on the bioenergetic properties of charcoal briquette from sengon wood wastes. Sengon wood waste charcoal was produced with a pyrolysis method at a temperature of > 500 ℃. The charcoal briquettes were produced by mixing charcoal powders with tapioca starch with 5%, 10%, and 15%. The mixed charcoal powders and adhesives were then put into a metal cast and pressed using a Universal Testing Machine (UTM) Testometric M500-50AT under compression of 2,59-5,17 N/mm2 and a target density of 0,5 g/cm3. Biomass briquettes from sengon wood particles were also produced for comparison. The results showed oven-dry density of 0,23-0,25 g/cm3 and 0,18-0,20 g/cm3, for charcoal briquettes and biomass briquettes, respectively. Higher adhesive content increased the density of briquettes. Charcoal briquettes were more hydrophobic than biomass briquettes (control), showing a lower moisture content than control samples. The results of proximate analysis of charcoal briquettes showed volatile matter of 24,96–31,80%; ash content of 3,16–3,24%; and fixed carbon of 58,68–66.40%. Higher adhesive content increased the volatile matter, moisture content, and ash content of the charcoal briquettes and decreased the fixed carbon. The charcoal briquettes have a calorific value of 25,68-27,35 MJ/kg (6.137,67- 6.536,80 cal/g), which is remarkably higher than the control. Higher adhesive content tended to decrease the calorific value of the charcoal briquettes. Lower adhesive content will produce briquettes with good bioenergy characteristics. Sengon wood waste charcoal briquettes with 5% adhesive content have great potential to be developed as an alternative energy source.

Forests had an important role in carbon reserve and uptake: where this was one of efforts of global warming’s impacts mitigation. The aim of this research was to know the effect of density in potential of carbon reserve and uptake in the private forest. Data collection was carried out by survey; then the collected data were analyzed for tree biomass, necromass, litter and ground plants, total of carbon stock in one area, suitability of carbon stock, CO2 absorbtion, and the differences in carbon stock and carbon uptake in each of density class. The result showed that, forests with low density were significantly lower in stored carbon and CO2 absorption, respectively 54.57 tons/ha and 200.27 tons/ha. In medium and high density forests, both the amount of stored carbon and CO2 uptake were no different. At medium density, stored carbon was 79.78 tons/ha, and CO2 absorption was 292.79 tons/ha. In high density, stored carbon was 92.94 tons/ha and CO2 absorption was 341.09 tons/ha.

Forestry partnership is a social forestry scheme as an attempt resolution of conflict society and permit holders. The objective of the research to explain the forestry partnership program conducted by PT REKI and the people of Dusun Kunangan Jaya I. This research used a qualitative research approach. The methods of data collection include in-depth interviews, participant observation, and document studies. The results of the research showed a forestry partnership carried out by PT REKI and KTH Berkah Jaya, KTH Bungin Mandiri and indigenous people of Batin Sembilan. The agroforestry pattern is applied to partnership lands. The percentage of forestry partnership outcomes, 85% for the community and 15% for PT REKI. The rights and obligations that have not been achieved have an impact on hampering agroforestry management. The limited funding of PT REKI, which depends on donors as a source of income causing the forestry partnership program has not been maximized. PT REKI in supporting forestry partnership provides various facilities including the provision of forestry plant seeds, cattle, education, and health services community empowerment. The rejection of forestry partnership cooperation carried out by most of the community because of mismatch between the expectation of community and PT REKI. The performance of the government in forest monitoring needs to be improved to support forestry partnerships to cut down land conflicts while improving community welfare.Forestry partnership is a social forestry scheme as an attempt resolution of conflict society and permit holders.

Hunting for wildlife in Way Kambas National Park (WKNP) is one of the leading causes of humans and animal conflict. So far, patrol activities are still considered less than optimal because of the decline in animal populations due to frequent hunting. This study aimed to analyze the findings of forest ranger patrols in protecting wild animals from hunting in WKNP. Data collection was carried out by observation, interviews and literature study. The data collected from the literature were then analyzed descriptively qualitatively. The results showed that during patrol activities, the finding of snares was still very much used by hunters and also found elephants that died due to hunting, although the range of forest rangers every year had increased but the number of personnel who did not match the size of the forest area made some areas not can be protected.

Pola tanam agroforestri merupakan sistem pengelolaan lahan yang banyak diterapkan dalam pemanfaatan lahan hutan melalui penggabungan antara tanaman kehutanan dan tanaman pertanian. Dalam pengelolaanya, petani memiliki cara tersendiri yang dipengaruhi oleh budaya dan kearifan lokal yang diwarisi orang tuanya. Untuk itu penelitian ini bertujuan untuk mengidentifikasi budaya dan kearifan lokal petani dalam pengelolaan lahan dengan pola agroforestri. Pengambilan data telah dilaksanakan pada bulan Februari-Maret 2021 dengan studi kasus di 3 Gabungan kelompok tani (Gapoktan) yaitu Gapoktan Hijau Makmur, Gapoktan Mahardika, dan Gapoktan Cempaka yang berada dalam wilayah Kesatuan Pengelolaan Hutan Lindung (KPHL) Batutegi, Provinsi Lampung. Penentuan besarnya responden menggunakan teknik purposive sampling yang difokuskan pada petani agroforestri. Pengumpulan data dilakukan dengan wawancara terstruktur menggunakan kuisioner dan wawancara mendalam. Pada penelitian ini teridentifikasi bahwa cara pengelolaan lahan petani dipengaruhi oleh budaya berupa kegiatan ngoret, angin-anginan, nunas, perantingan dan setek pada pemeliharaan tanaman, mutil dan ngunduh pada kegiatan pemanenan dan pembibitan. Selain itu budaya ini juga mengandung kearifan dalam kegiatan babat belukar pada penyiapan lahan dan nandur pada penanaman. Kearifan lokal ini masih diterapkan secara terbatas sehingga perlu dikembangkan agar dapat diterapkan secara luas untuk mendukung kelestarian hutan di KPHL Batutegi.

The growth rate of Paraserianthes moluccana is effected by the planting medium quality. Biochar is a soil-improving agent that could improve soil quality. This study aimed to determine the effect of biochar made from meranti wood (Shorea spp.) by pyrolysis temperature at 400°C and 600°C and dose at 0 ton/ha, 25 ton/ha and 50 ton/ha factors through the growth rate of P. moluccana. The P. moluccana was planted within 2x2 m in the field. The size of planting holes was 100 x 60 cm, the biochar was placed at a depth of 100 cm to 20 cm, then it was covered with soil so that the root did not interact directly to the biochar. This research used 6 months old P. moluccana seedling, and was planted in field demplot for 8 months. The research used the Split Plot experimental design with 5 treatments and 7 repetitions. Data analysis used Analysis of Variance (ANOVA) and Least Significance Different (LSD). The effect of biochar could be seen since the 4th month of plantation. The results showed that biochar with a dose of 25 ton/ha and pyrolysis temperature of 600°C had a very significant effect on the increment of height and significant on diameter steam increment of P. moluccana; increased the rate of stem height 22.6% and stem diameter 23.6% faster than the control. Further research related to the dynamics of P. moluccana growth with a longer time is needed because the physical properties of biochar change over time.
