Abstract

Binuang bini (Octomeles sumatrana Miq) is a fast-growing tree with numerous economic benefits, such as the provision of wood for carpentry purposes, building boards, water management, and absorption of carbon dioxide (CO2). Therefore, this tree species has great potential and needs to be included in Reducing Emission from Deforestation and Forest Degradation (REDD)+'s mitigation program to tackle climate change. In its development, REDD+ has made it possible to carry out carbon trading in the world. Therefore, countries capable of performing protective functions and carry out reforestation, afforestation, and restoration, have the opportunity to be involved in world carbon trading. This study aims to determine the moisture content and carbon absorption rate of Binuang bini trees as a first step to regulate the allometric equation using destructive and laboratory analysis. The results show that the water content in the roots, leaves, as well as the base, middle, and tip of the stem were: 73.69%, 68.39%, 65.59%, 61.22%, and 66.26%, respectively. Furthermore, the sample test results indicate a very close relationship between carbon concentration and absorbance in the O. sumatrana tree with a simple linear regression equation: Y = 0.002X + 0.0593 with R2 = 0.9896. Therefore, this regression equation can be used to calculate the carbon concentration sample for the O. sumatrana tree fraction. The carbon content in 3 tree samples with a breast height diameter of 9.24 cm, 10.08 cm, and 11.68 cm was 2,585 kg. 2,913 kg, and 4,654 kg, respectively. In addition, the carbon sequestration for each tree diameter per year is 1.581 kg year-1, 1,782 kg year-1and 2,847 kg year-1, respectively.

Abstract

Mount Hamiding Protected Forest (HLGH) is administratively located in North Halmahera Regency and has a role in supporting living systems, regulating water management, preventing floods and seawater intrusion and increasing soil nutrients. The current condition of HLGH is experiencing damage due to human activities, namely forest encroachment, shifting cultivation and illegal logging. The research aims to determine community perceptions and attitudes in managing protected forests. This research was conducted in the HLGH area, taking place from July – November 2022. This research used a quantitative and descriptive qualitative approach. The parameters measured are community perceptions and attitudes in managing protected forests using a Likert scale. The results of the research show the perceptions and attitudes of the community in the six research locations, namely Roko village, perception value 26.95, attitude 11.97, Soakonora perception 27.36, attitude 11.87, Togawa perception 24.68, attitude 12.51, Mamuya Perception value is 26.78, attitude 11.47, Efi perception -Efi 27.18, attitude 12.17 and Wangongira perception 24.77, attitude 12.68. These findings illustrate that the perceived value in four villages is at a medium level, and two other villages are at a low level. The attitude of the six villages is in the medium category. This illustrates that people's perceptions and attitudes towards the existence, function and benefits of protected forests are still below standard. Thus, there is a need for outreach activities about the existence of protected forests and their functions and benefits to improve community perceptions and attitudes.

Abstract

The Mount Hamiding protected forest is located in North Halmahera district, North Maluku Province, Indonesia, which has high biodiversity but has not been managed optimally. In general, the study shows that communities around forest areas have low incomes. However, actual data regarding community welfare at the location level is unavailable. This research aims to assess the level of community welfare and income distribution in protected forest management. The methods used in this research are descriptive qualitative, quantitative. Data collection was carried out through observation, interviews, and literature study. Analysis of the level of community welfare refers to Sayogjo and inequality is measured using the Lorenz curve. The welfare level variable is determined using non-parametric chi-square statistical analysis. The research results show that people still live below the poverty line, and the average per capita income is IDR 3,913,255/year, the Gini Ratio is 0.3 in the low category. Community characteristics: education, number of dependents, distance from house to forest, income, and length of residence have a significant effect on welfare. Meanwhile, age, occupation, and land area do not have a significant effect. To improve community welfare, multi-party collaboration is needed for training and community empowerment activities.

Abstract

Protecting the nesting habitat of the Moluccan Scrubfowl (Eulipoa wallacei) is important to conserve the population of this endemic species in North Maluku. The success rate of semi-natural hatching nests of Moluccan Scrubfowl varies in each hatchery conservation location. This study aims to determine the nest success of semi-natural hatching program of Moluccan Scrubfowl in Mamuya Village, North Halmahera Regency. A field experiment approach was used to estimate nest success in semi-natural (in-situ) incubation treatments. Eggs used for the semi-natural hatching treatment were collected from landowner egg collecting activities at four Moluccan Scrubfowl nesting sites. In semi-natural hatching, each bird egg was placed in 60 cm of sand with a minimum distance of 10 cm between eggs (egg density adjusted to the number of eggs planted). A total of 116 Moluccan Scrubfowl eggs were planted over four planting periods and during the natural incubation period the eggs hatched producing 96 chicks. The nest success of the semi-natural hatching program for Moluccan Scrubfowl in Mamuya Village has a high success value of 0,835 (83,52%). This optimal success indicates that incubation in the chick embryo formation process is stable on the sand substrate. The mean incubation time interval for hatching eggs lasted 74 days (interval 72 - 76 days)
