This study aimed to determine the quality of defective honey, bitter honey, and sweet honey produced by the Baduy community. The bitter honey was collected from locations where nectar was sourced from calliandra, mahogany, sengon, and kamboja trees. The sweet honey was collected from locations where nectar was sourced from fruit trees such as bananas, sugar palm, durian, jackfruit, and rambutan. The defective honey is sweet honey that produces gas and therefore it is bubbly and considered to be damaged by the Baduy community. The research applied the criteria of the Indonesian National Standard SNI 8664 (2018) to test the quality of honey. The results showed that defective honey fulfills five criteria, i.e.: HMF testing, ash content, insoluble solids in water, acidity, smell, and taste. Bitter honey fulfilled four criteria, i.e., testing of ash content, water-insoluble solids, acidity, and moisture content. Sweet honey fulfilled seven criteria, i.e., the testing of ash content, sucrose, water-insoluble solids, acidity, moisture content, odor, and taste. All types of honey did not meet the criteria of diastase enzyme activity and reducing sugar levels. This could be due to conditions and storage time of honey before testing.

This research aimed to assess the feasibility of herb agroforestry utilization in the community forest of Gerbosari Village, Kulon Progo. This research measured NPV (Net Present Value), Net B/C (Net Benefit-Cost Ratio), IRR (Internal Rate of Return), and AEV (Annual Equivalent Value) as the financial feasibility criteria. A stratified sampling method was employed in which sixty farmers were classified into three strata based on the size of their lands. Based on the financial feasibility analysis, in stratum I, the values of the criteria measured were NPV of IDR15,757,980.56/ha/25 years, Net B/C of 1.62, IRR of 22.12%, and AEV of IDR1,296,647.20/year. In stratum II, the values of criteria measured were NPV of IDR14,255,408.39/ha/25 years, Net B/C of 1.76, IRR of 23.78%, and AEV of IDR1,173,007.88/year. Finally, in stratum III, the criteria measured were NPV of IDR19,444,703.86/ha/25 years, Net B/C of 2.21, IRR of 32%, and AEV of IDR1,600,009.64/year. The results suggest that herb agroforestry plays an important role in farmers' livelihood particularly as a source of income in both the short and long terms. The herb agroforestry utilization contributes positively to the economy of Gerbosari Village, Kulon Progo District.

This research aimed to analyze the socio economic and its dynamics of the community in Sidomukti Village, Dendang District, and Pandan Sejahtera Village, Geragai District, Tanjung Jabung Timur Regency, Jambi Province. Respondents were selected purposively based on their farming practices on deep peatlands. Thematic and descriptive analyses were used in this research. The results showed that the majority of the communities of the two villages was Javanese who came to the villages through transmigration programs in the 1980s. Their had insufficient knowledge about peatland utilization because they used to manage mineral soil in their place of origins. Their main jobs were farmers, planters, and laborers with oil palm and areca nut as the main commodities. The average income in Pandan Sejahtera Village was IDR3,832,800/month, greater than in Sidomukti Village which was IDR3,661,850/month. Farmers tended to plant commodities that were currently favored in the market instead of their suitablility with the biophysical conditions of peatlands. Guidance is needed to improve farmers’ knowledge of land management and species selection that have high economic values and market captures as well as are suitable for biophysical properties of deep peatlands and agroforestry techniques.

Law enforcement plays a vital role to prevent the extinction of endangered species, including the Sumatran tiger. We investigated the roles of private sector involvement in Tambling Wildlife Nature Conservation (TWNC) for supporting law enforcement by Bukit Barisan Selatan National Park (BBSNP) agencies. We explored the relationship between law enforcement in the environment and forestry on illegal activities within the habitat of the Sumatran tiger in the TWNC area. We collected data on law enforcement and illegal activities during the period of 2000-2018 from BBSNP and TWNC management through secondary data and conducted semi-structured interviews with selected persons, including managers and staff. Additional data on illegal activities data was also obtained through the SMART programme. Our study showed that law and non-law enforcement approaches on environment and forestry during 2001-2018 reduced illegal activities within the TWNC area. However, the approach was not effective to reduce illegal activities if not implemented synergistically. This was evidenced by the guard posts burning case in the TNWC area. We highlighted that the law and non-law enforcement approach on environment and forestry must be implemented involving more synergy ways to reduce illegal activities in the habitat of Sumatran tiger in TWNC.

Community forest plays an equally important role in ecological aspects when compared to other types of forest, one of which is carbon storage that helps in mitigating global climate change. The existence of community forests that are part of urban areas is quite rare, so this research needs to be carried out considering its special location. This study aimed to estimate the carbon storage contained in urban community forests, Bandar Lampung City, Lampung Province. The methods used in this research were destructive and non-destructive. Carbon storage measurements were carried out in three carbon pools, namely aboveground biomass; necromasses; litter, and understorey. The measurements were carried out by a vegetation inventory on 15 plot clusters located in the study area. The results indicated that the average value of carbon storage was 54.59 tC/ha with a value interval of 48.93 tC/ha up to 60.26 tC/ha. Aboveground biomass held the largest percentage as a contributor to carbon storage 95.71%, followed by necromass 4.23%, litter and understory 0.05%.

Around 12.62% of watersheds in Indonesia are damaged and need restoration immediately to prevent floods, landslides, and other related disasters. This study aimed to evaluate the Wosi watershed and formulate conservation scenarios to improve its conditions. The data collection included hydrology (quantity, continuity, and water quality), land (critical land index, percentage of vegetation cover, and erosion index), socio-economic (population pressure, welfare level, existence, and regulations enforcement), building investment (city classification and water building value classification), and the use of space (protected areas and cultivation areas). The evaluation of carrying capacity used a scoring analysis. The scenarios formulation used the information on potential carrying capacity and conservation strategies. The results suggested that the carrying capacity of the Wosi watershed from 2016-2019 had fallen into "bad" and "very bad" categories. To improve these conditions, the government can assign the riparian areas as a government asset, build ponds and dikes in the flood-prone areas, apply small recharge pond (SRP) on the cacao plantations, and assign Wosi Rendani protected forest (HLWR) as an urban forest. The implementation of these conservation strategies will result in the improvement of (a) the carrying capacity of the Wosi watershed and (b) the status into the "good" category to support environmentally friendly development in Manokwari city.

The number of visitors to Kalibiru Nature Tourism Object in Kulon Progo Regency during weekends has exceeded its effective carrying capacity. Distributing the visitors on weekdays could become one of the solutions to prevent ecological damage. This research aimed at better understanding the relationship between visual landscape quality and the level of visitors’ experience in Kalibiru Nature Tourism Object, Kulon Progo Regency. Two independent surveys were conducted, one during the weekdays' dan another one during the weekends in which 100 respondents were randomly selected for each survey. This research employed descriptive analysis, t-test for independent samples, and simple linear regression. The results showed that there is no significant difference between the average score of landscape visual quality between weekdays (score 75.44) and weekends (score 78.01). Similarly, there is also no significant difference between the level of visitors’ experience during weekdays (score 78.09) and weekends (80.34). The simple linear regression analysis indicated that the landscape visual quality has a positive influence on the level of visitors’ experience in both categories.

Herpetofauna is poikilotherm and sensitive to temperature change in particular fires, understanding response of these taxa after fire could provide early evidence of ecosystem resilience. It seems very few scientific evidences have been reported for the response of herpetofauna communities after fire. We aim to explore the presence of herpetofauna in the ex-burnt areas of Tesso Nilo National Park in Riau Province and find possible environmental conditions which explain their presence. Field work was conducted during December 2015-February 2016 for collecting presence of diurnal herpetofauna species in burnt and un-burnt areas as well as collecting environmental conditions through transects. Numbers of individual sightings during observation were recorded and measurement of environmental conditions included habitat covers, vegetation density using protocol sampling and nested sampling plots. We also calculated vegetation mortality and composition of dead organic matter for each sites. Fires in 2015 have caused a clear difference on the habitat condition for herpetofauna between burnt and un-burnt, whereas the composition of herpetofauna species was higher in un-burnt areas (10 species) than burnt areas (5 species). Frogs were found in burnt area, confirms their ability to survive in disturbed areas.

Mangrove planting in Progo River Esturaine in Kulon Progo was hindered by its marginal conditions, where the land was dominated by very dynamic sandy substrat. This condition has caused the growth of various planted mangrove seedlings by Forestry UGM team (2015-2016) was very low. Nevertheless, it was found that Sonneratia can grow well in the location. It was expected that Sonneratia can improve site condition so it became suitable for the growth of other mangrove species. This research aimed to assess soil properties of Progo River estuarine after rehabilitation using Sonneratia. Characterisation of soil physical (texture) and chemical (salinity, pH, and soil organic matter) properties were conducted in the Laboratory of Tree Physiology and Forest Soil, Faculty of Forestry UGM. Soil samples were collected from Sonneratia plant area in various growing conditions. The results showed that growth of Sonneratia affected soil physical properties particularly increasing the proportion of clay and silt, but not soil texture class. In general, more proportion of clay and sand were detected in the bigger Sonneratia plants and in the outer section of root system. The growth of Sonneratia also affected soil chemical properties particularly soil organic matter but not soil pH and salinity.
