The economic value of Indonesia\u27s tropical rainforest park (TH2TI) in South Kalimantan
Full text linkUrban forest is a form of environmentally oriented development. One form of urban forest in South Kalimantan is the Indonesia’s Tropical Rain Forest Park (TH2TI). This study aims to calculate the total economic value and future value of TH2TI. The total economic value calculated in this study consists of direct use value (recreation, wood, carbon and oxygen), indirect use value (water absorption), and option value (existence and heritage). The method used in this research was quantitative research method to calculate the value of wood, carbon, oxygen, and water absorption and qualitative research method to calculate the value of recreation, existence, and heritage. Results indicated that the economic value of recreation was the highest amounted to IDR 1,568,514,750.00 and the total economic value of TH2TI amounted to IDR 3,085,373,964.75. In the next 5 years, the economic value of TH2TI could reach IDR 3,664,456,405.74. The knowledge of the economic values of TH2TI is expected to make people aware to the importance of the environment for life
Factors Behind Cessation of Illegal Logging by Local Communities for Valuable Timber-producing Endemic Species, Hopea celebica
Full text linkHopea celebica is a species of Dipterocarpaceae that produces strong and durable wood. This species is endemic to Sulawesi Island, where its spread is restricted to specific habitat types in the southern part of the island. The high quality of the wood has exposed this species to high levels of illegal logging and is endangered. However, in the last two decades, the threat of logging to this tree species has ceased to occur. Through field surveys and interviewing of respondents in 6 small FGDs, this study aims to determine the factors behind the cessation of illegal logging activities. We found that this species has good regeneration ability and identified 3 leading causes of stopping illegal logging of H. celebica: restricting its habitat to the Bantimurung Bulusaraung National Park, the change in cultural interest from building houses on stilts to concrete houses, and the shift in the lifestyle of young generation who are no longer interested in working as woodcutters. Thus, the cessation of illegal logging of H. celebica is not due to the correct public perception of the importance of conserving H. celebica to increase its population so that it can be used sustainably in the future. The Bantimurung Bulusaraung National Park still needs to make people aware of the importance of H. celebica conservation
Modeling suitable habitats of stingless bee klanceng (Tetragonula laeviceps) in Merbabu Mountain areas related to elevation, temperature, and humidity variables
Full text linkKlanceng is one of the stingless bee species in Indonesia with the scientific name Tetragonula laeviceps. This bee species has sustainable economic values since it has a role as a pollinator. This species is also common in mountainous areas, including Merbabu Mountain, Central Java. Despite this bee being very common, information about potential distributions of this bee is very limited, and this information is needed for its management. This study aimed to model the potential habitat for T. laeviceps using species distribution modeling (SDM) with elevation, temperature, and humidity as predictors. The model was built based on the T. laeviceps occurrence points gained through field surveys, with a total of 23 sampling points. According to the model, most of the west parts of Merbabu Mountain were considered not suitable for T. laeviceps. This suitability is also similar to the north and south parts. This condition is in contrast to the areas that bordered with the Merbabu Mountain directly. Most areas adjacent to the Merbabu Mountain were having high and very high suitability for T. laeviceps. Regarding altitudinal distribution, T. laeviceps was limited at elevations of 1000 m
Growth rate and carbon storage capacity of mangroves along the Tambakrejo Coastal Zone
Full text linkThe existence of mangroves is essential as a mitigation agent of the impacts of climate change. Mangroves serve as abrasion protection and a carbon storage agent, reducing greenhouse gas emissions. This study aimed to examine growth rate and carbon storage of mangroves as a determination of a rehabilitation potential for abrasion-exposed degraded mangroves. This study used a quantitative approach. Data was collected in November 2021 at the Tambakrejo coast, located in the north coast of Semarang. The results showed that the highest growth rate occurred in the 5–6-year period with the diameter of 0.11 cm (about 0.04 inch)/month and in the 4–5-year period with the height of 3.54 cm (about 1.39 inch)/month. The regression analysis showed moderate level of relationship between diameter and height values. This was used to determine both height and diameter values. Among different tree age classes, the age class of 72 showed the highest storage capacity, reaching 45.6 kg CO2eq, with average annual addition of 7.5 kgCO2eq/year. This indicates biomass addition is positively related to the storage capacity. Thus, anything that can alter the mangrove tree biomass will affect its carbon storage capacity
The perception of waste management of hikers at Bulusaraung mountain area of Bantimurung Bulusaraung National Park
Full text linkWaste management in tourist destinations is a serious problem because of its non-biodegradable nature and the volume of waste produced each year continues to increase along with the increasing number of visitors to the tourist area. The existence of climbing activities in the Bulusaraung Mountains area has an impact on the waste problem that arises due to hikers activities in the area. This study aims to examine the effectiveness of waste management in the Bulusaraung Mountains, Bantimurung-Bulusaraung National Park (South Sulawesi), Indonesia from the perspective of hikers, a survey was conducted on 100 hikers with a focus on their perceptions, attitudes and awareness using a set of questionnaires. Additionally, observations were made regarding the implementation of hiking procedures applied by the National Park on waste management in the area. A correlation analysis determined the relationship between socio-demographic factors and hikers\u27 perspectives on waste management in the Bulusaraung Mountains. The results, which underscore the importance of this study, indicated that hikers held positive perceptions, attitudes, and awareness regarding the waste management efforts implemented by Bantimurung Bulusaraung National Park. Age and education positively influenced hikersperception, attitude, and awareness towards waste management. In addition, a significant correlation was found between age and awareness (p = 0.05). Other variables, such as gender, occupation, and organization, were negative and insignificant in influencing hikers\u27 perception, attitude, and awareness (p > 0.05). Respondents‘ education is positively correlated with hikers’ perceptions, attitudes and awareness towards waste management in the Bulusaraung Mountains
Ethnoecology: The Community Adaptation Patterns of Forest Management in Grobogan Central Java
Full text linkThe aims of this research are to describe community adaptation patterns and determine community perceptions regarding forest environmental management. This qualitative research was studied using an ethnoecological approach with the research focus being the people of the Perhutani area of Grobogan Regency. This research carried out the data collection through interviews, observation and documentation, with the main informant being Pesanggem as a forest land manager. This research produced the first findings in the form of community adaptation patterns in managing the environment covering three aspects, namely ecological adaptation, economic adaptation and social adaptation in the Pesanggem community in Gedangan Village, Wirosari District under the auspices of BKPH Sambirejo. 1) Ecological adaptation in Pesanggem showed the availability of well water which previously only relied on rainwater, then adjustments to various types of plants, as well as an understanding of prohibitions and sanctions for illegal activities in forest areas; 2) economic adaptation showed an increase in income for Pesanggem from forest land management; 3) social adaptation showed the existence of cooperation between members and other farmer groups within the LMDH forum. The second finding is that the public\u27s perception in interpreting environmental management is that there are 5 values, namely the values of wisdom, independence, religion, creativity and healthy living. Based on the research results, the author recommends that forest area communities be involved in managing and guarding forests for generational sustainability, and Perum Perhutani should invite partners from surrounding school institutions as a means of educating generations in joint forest management
Social Ecological Resilience System of Ambon Island Protected Forest, Maluku Province, Indonesia
Full text linkHumans and nature cannot be separated because both have a close relationship as an ecosystem. The purpose of this study was to determine: 1) the level of social and ecological resilience; 2) Scenarios on ecological and social factors for the sustainability of protected forests. The research method uses survey methods and data analysis uses qualitative-verification analysis based on the results of the calculation of the resilience index and the phase of the socio-ecological system. The results showed that the level of social and economic resilience was partially or simultaneously at the level of resilience with their respective indexes: social: 0.6944); ecology: 0.8148 and socio-ecology 0.7460. The exploitation phase (growth) leads to the conservation phase. The results of the scene show that both of them are at a high level of resilience with a resilience index of 0.8889 (high resilience) and a reorganization phase. If this phase can be maintained with various management interventions according to its function, it will minimize the level of disturbance to the Mount Sirimau Protection Forest Group

Nickel acquisition affected by root density of mono- and mixed-cropping peanut and choy sum
Full text linkNickel (Ni) and associated minerals (Cr and Mn) are naturally occurring substances in ultramafic laterites soil. It may be found in our vegetables and grains when agriculture is grown in ultramafic laterites. This study aimed to assess the contamination of Ni in edible crops affected by soil volume in mono- and mixed cropping on limonitic laterite soil. The investigation was conducted on Peanut (Arachis hypogaea L.) and Choy Sum (Brassica rapa var. parachinensis) in three different pots sizes-representing soil volume to support root growth, which was filled with 0.5 kg (small), 1.0 kg (medium), and 1.5 kg (big) of limonitic laterite soil, respectively. The limonitic soil has a 7.884 mg kg-1 Ni concentration. The experiment shows that Ni concentration in peanut and Choy Sum shoots of mono-cropping in small, medium, and big pots achieve 20, 90, 120 mg kg-1 and 51, 67, and 95 mg kg-1, respectively. Meanwhile, in mixed cropping, Ni concentration in small, medium, and big pots of peanut and Choy Sum shoots are lower only by 33, 50, and 51 mg kg-1 and 15, 52, and 63 mg kg-1, respectively. Contamination of Ni in Peanut and Choy Sum shoots increases with the increasing soil volume, and mixed cropping is a potential strategy to reduce the acquisition of Ni
