The potential for coffee development in Indonesia has great opportunities, supported by high market demand. The purpose of the study was to determine the characteristics of coffee agroforestry and its contribution to the income of farmers in Tulungrejo Village, Ngantang District, Malang Regency. Types of data consist of primary data and secondary data. Primary data were obtained from interviews with 90 respondents of coffee agroforestry farmers who are members of the Forest Farmers Village Partnership Institute (LKDPH). Data processing used quantitative descriptive analysis by calculating production costs, revenues, and income, as well as the contribution of coffee agroforestry to the total income of farmers. The results showed that farmers applied agrisilviculture with a simple system, namely planting robusta coffee (Coffea canephora) under forest tree stands. The value of the R/C ratio is 2.98 where the value is >1, meaning that coffee agroforestry farming provides benefits. The application of coffee agroforestry contributes significantly to the total income of farmers, which is 58.47%. The development of coffee agroforestry is directed at increasing productivity and quality without damaging the shade plants. The policy implications of coffee agroforestry development must involve all relevant parties including the government, entrepreneurs, farmer groups, banks, and cooperatives.

Jabon putih (Neolamarckia cadamba (Roxb.) Bosser) is a species of forest plant that is widely grown for pulp raw material of paper and carpentry wood, in plantation forests, village forests, and community lands, so it is necessary to prepare good quality seedlings. This research was conducted for the propagation of jabon putih seedlings by stimulating their growth using various media compositions and compost doses. This research was carried out in the nursery area of the Environmental and Forestry Research and Development Center of Makassar for three months, from October 2019 to January 2020. This study used a completely randomized design with a factorial pattern with four replications. The treatment used various media compositions consisting of soil, sand, husks as the first factor, and compost dose as the second factor. The variables observed were the growth of seedlings including height, stem diameter, and number of leaves. The interaction of media composition and compost dose had a significant effect on the growth of jabon putih seedlings in the nursery. The best media composition was a mixture of soil, husks, and sand with a ratio of 2:1:1 and the provision of 40 g of compost per polybag, which could increase the growth of seedling height by 68.62%.

Benuang laki (Duabanga moluccana) is a potential fast-growing tree species to be developed in plantation forests, community forests, and land rehabilitation. This species has a very fine seed size that requires special treatment in germination, both in testing activities in the laboratory and operational activities in the nursery. The purpose of this study was to determine the optimum germination technique for benuang laki seeds in the laboratory and greenhouse. A completely randomized design arranged with a factorial pattern was used to determine the effect of the test method and lighting period in the laboratory, and the effect of sowing media and germination conditions in the greenhouse. To obtain a reliable and reproducible germination method, the tests were carried out involving 3 seed lots. The results showed that the top-of-paper test method with a lighting period of 24 hours resulted in the highest germination capacity and germination rate, i.e., Semboja (415 seedlings/0.05 g and 30.17 seedlings/day), Cianjur (253 seedlings/0.05 g and 19.47 seedlings/day), and Rarung (158 seedlings/0.05 g and 12.34 seedlings/day), respectively. The highest germination in the greenhouse was produced by the treatment of sand + topsoil (1:1, v/v) media covered with transparent plastic, with a germination capacity of 870 seedlings/0.1 g of seed and a germination rate of 28.13 seedlings/day.

Changes in the area of mangroves in the coastal area of Maros Regency have been degraded from year to year. Various problems that often occur cause a decrease in the distribution and quality of mangrove community health. This happens because there is still pollution and external disturbances which make the quality of the mangroves decrease. Therefore, it is important to know the condition of mangrove distribution to find the latest information and baseline data for area managers. The purpose of this study was to obtain information on the extent and type of mangrove health, as well as identify the types of mangrove damage in the coastal area of Maros Regency in 2021. This research method used (1) supervised classification, to obtain mangrove distribution, (2) analysis of mangrove health using the normalized difference algorithm vegetation Index, (3) map overlay, mangrove distribution map, administrative map, and mangrove health index map, (4) validation of mangrove health data through an assessment of mangrove conditions based on the distribution of observational plots in a proportionate stratified with random sampling. Mangrove areas are found in the coastal areas of Maros Regency and are scattered in Marusu District, Maros Baru District, Lau District, Bontoa District with an area of 131.87 ha, 95.59 ha, 85.37 ha, and 60.01 ha, respectively. Mangrove health is divided into 5 categories, namely excellent, good, normal, bad, and awful with an area of 100.73 ha, 240.43 ha, 1.99 ha, 9.5 ha, and 20.2 ha, respectively. While mangrove damage based on 30 sample points, 6 types of damage were identified, namely changed leaves, damaged shoot leaves and shoots, broken/dead branches, open wounds, resinosis, and broken stems with percentages of 29.91%, 19.63%, 17.76%, 16.82%, 12.15%, and 3.74% respectively.

Indonesia is a biodiversity-rich country with the second-largest tropical forest in the world. One East KalimantanForest area in focus is the Hemaq Beniung Customary Forest. The Hemaq Beniung Customary Forest is the first customary forest with its license granted in East Kalimantan by the Ministry of Environment and Forestryof the Republic of Indonesia. Information on vegetation diversity is essential to ensure sustainable management of this forest area. This research provides such information through a survey with purposively chosen samples representing HemaqBeniung Customary Forest. The study reveals that the Importance Value Index of vegetation in different habitus (i.e., seedling, sapling, pole, and tree) are low, except for Elateriospermum taposBlume, which has a moderate value for the vegetation at the pole and tree habitus. The research also shows a high Richness Index (R), high Diversity Index’(H'), an almost evenly distributed Evenness Index (e), and a low Dominance Index (C). Syzygium borneensis(Miq.) Miq. and Knema elmeriiMerr. have the highest Importance Value Index for seedling and sapling habitus, respectively, while Elateriospermum taposBlume has the highest Species Significance Index for both pole and tree habitus. This study also found two dipterocarp tree species categorized as Critically Endangered (CR), namely Shorea johorensisFoxw. and Shorea lamellataFoxw. The presence of these CR species calls serious attention to managing the Hemaq Beniung Customary Forest mainly for hydrological function and conservation purposes while improving local communities' economy.

The tree species preferred by forest farmers are not always the same, so that in each farmers cultivated block it is possible to form forest stands with a certain composition. The research aimed to analyze the composition of tree species, dominant tree species, and similarity level of species composition among the farmer’s cultivated block. The research was conducted from August until December 2020. Data collection was carried out with a vegetation survey using nested rectangular plots with a sampling intensity of 1%. The data collected includes tree species, tree height, basal area, and individual number of each species. Data were analyzed by calculating density, frequency, important value index (IVI), similarity index (IS), and dissimilarity index (ID). The results showed that the composition of forest garden stands in the farmer’s cultivated block was categorized as heterogeneous (mixed stand) with the number of trees species varying from 12 to 18 species. The total number of tree species were 43, consisting of 17 jungle wood species, 18 jungle MPTS species, and 8 agricultural MPTS species. The forest garden stands were dominated by 4 tree species, namely Gnetum gnemon, Durio zibethinus, Aleurites moluccana, and Myristica fragrans, each of which had an IVI>19.91%. The similarity level of forest garden stands composition was very low with an average IS of 0.27 and an average ID of 0.73. Thus, it can be stated that the forest garden stands among the farmer’s cultivated blocks had different compositions with a difference of 73%. The heterogeneity of forest garden stands needs to be maintained and even developed so that the ecological function of the forest is maintained and the non-timber produced is sufficiently diverse to meet the needs of communities living around the forest.

Sangalaki Island Nature Tourism Park (NTP) is one of the tourist destinations in Derawan. As a conservation area, tourism development in Sangalaki Island NTP must pay attention to the carrying capacity of the area. The purpose of this research is to calculate the carrying capacity in the NTP area of Sangalaki Island. The research was conducted in October 2021 through literature studies, field observations, and interviews. The calculation of the carrying capacity is carried out with the concept of Physical Carrying Capacity (PCC). The PCC of the area in Sangalaki Island NTP is 259 people/day with details of beach tourism 77 people, snorkeling 69 people, diving 44 people, tracking 13 people, and animal watching 57 people. The PCC data can be the basis for the manager to determine the maximum number of visits that can carry out tourism activities at Sangalaki Island NTP. Carrying capacity is intended to reduce the impact of tourism development on the ecological aspects of the area. In addition, the application of environmental carrying capacity is a manager's step to apply the concept of sustainable tourism at Sangalaki Island.

Indonesia is one of the countries in the world that has experienced a negative economic impact due to the Covid-19 pandemic since early 2020. In overcoming this impact, the government has taken strategic steps by implementing the National Economic Recovery (PEN) program. One of the PEN programs implemented by the Ministry of Environment and Forestry is community economic development for peat farmer groups through the development of agroforestry food in 35 Social Forestry Business Groups (KUPS) in Pulang Pisau Regency, Central Kalimantan Province. It is one of the regencies known to have quite a large peatland area in Indonesia. This study aimed to analyze the risk management of the 35 KUPS PEN program in peatland. A qualitative desk study methodology was used along with the fishbone model analysis. The results showed that various types of business activities had been developed by KUPS. In the management of social forestry businesses, various riskswere identified starting from regional governance, institutional governance,and business governance. The PEN program implemented in 2020 showed a positive impact in improving the community's economy with a positive impact on ecology and socio-culture. This PEN activity has absorbed around 9,110 HOK (Working People'sDay) local workers with 565 KUPS members. The implementation of this program can be replicated, especially forsocial forestry business groups in other areas.

The objective of the research is to identify the impact of Intensive Indonesian Selective Cutting and Replanting System (TPTII/SILIN) at dipterocarp production forest on understory birds community. Two forest blocks were compared, one with TPTII/SILIN and the other with Indonesian Selective Cutting and Replanting System (TPTI). At each forest block, 10 of 4 x 10 m mist nets were installed for three days and then they were moved to other spot for other three days. Mist nets were opened from 06:00 to 17:00 and monitored every 15 minutes. The trapped bird was identified and body size measured, then subsequently released. Data was analyzed by using Important Value Index, Shannon-Weinner Diversity Index, Margalef Species Richness Index, Simpson Dominance Index, and Sorensen Similarity Index. Number of individu, number of species, Shanon-Wiener Diversity Index were compared statistically using student t-test. The result showed that Ceyx erithacus and Arcahnotera longirostra hold the highest important value index in TPTI and TPTII/SILIN respectively. Bird abundance, Shannon-Weinner Diversity Index and Margalef Species Richness Index were lower in TPTI than TPTII/SILIN. Meanwhile Simpson Dominance Index was higher at TPTI than TPTII/SILIN. Statistical analysis for the data of the two forest blocks showed significant differences on number of individual, number of species and Shannon-Weiner Diversity Index. TPTII/SILIN was better in supporting understory birds community than those of TPTI.
