. Sudan is a hot spot for deforestation, despite the increasing awareness of deforestation and its consequences. Consequences are related to increased emissions of greenhouse gases, water pollution, and loss of biodiversity. However, precise information on its forests' current state is very limited. Therefore, to intervene support of existing resources effectively, it is important to have a better understanding of the process to take place in the country and impact those resources. The objective of this study is assess and map Land use Land cover (LULC) change and analyze the anthropogenic factors causing it in Um Hataba forest, South Kordofan State. The study utilized two-free cloud images (TM 2000 and Sentinel-2 in 2018), field surveys, and questionnaires to analyze the decrease in forest cover. The results indicated there were a decrease in vegetation cover on wadis (clay soil) from 20.98% in 2000 to 15.85% in 2018 and vegetation on sandy soil decreased from 30.29% in 2000 to 30.13% in 2018. While mixed shrubs and grassland increased from 28.60% in 2000 to 33.20% in 2018 of the total area under study and the rainfed agricultural area increased from 20.13% in 2000 to 20.82% in 2018. The main factors of degradation and fragmentation as the expansion of mechanized are rain-fed agriculture, felling of trees and woodcutting, worse grazing activities, and construction of infrastructure. Information garnered from this study can provide a good basis for forest rehabilitation programs and can also be used for developing proper management plans that consider the needs of the communities utilizing the forest.

Utilization of non-timber forest products, especially cajuput plants in Indonesia needs to be optimalized. The management of cajuput plantations should be supported with data and information toward sustainable management. The sampling approach to estimate the potential of cajuput leaves has no standard on plot size. The objective of this research is to determine the optimal plot size that can be used in inventory of cajuput plantation. Equipements used in this research are GPS, rope, bamboo, compass, digital scales, and quadcopter drones. The research material is cajuput stand which has good degree of normality. The method used in this research is making of nested sample plot of 20 x 20 m, 30 x 30 m, 40 x 40 m, 50 x 50 m, 60 x 60 m, 70 x 70 m, 80 x 80 m, 90 x 90 m, and standard plot (control) 100 x 100 m. Parameters measured were number of tree (n / ha) and the biomass of cajuput leaves-twig (Kg / ha). Data were analyzed by using t-student test to determine the difference of mean value between sample sample plot and control plot. The analysis is also done by calculating the precision of each sample plot. The result showed that the estimated value of number of tree (n / ha) of the 20 m x 20 m plot size was not significantly different with the control plot size of 100 m x 100 m. Estimation of leaves-twigs biomass of cajuput with plot size of 20 m x 20 m plot is also not significantly different with the result of measurement of leaves-twigs biomass of cajuput in control plot 100 m x 100 m. Thus, the optimum plot size that can be used in the study site is 20 m x 20 m.

A special-purpose forest area (KHDTK) is the forest area which the purposes are for teaching and research activities. One of the research conducted in KHDTK Wanagama was examining the planting of superior Teak from breeding (jati Mega). The growth of clonal teak data can also be assessed for its carbon stock. Hence, the purpose of this research was to determine the potential of biomass and carbon stock in the Jati Mega stands at KHDTK Wanagama, Yogyakarta. The research was carried out using a non-destructive method which used the allometric equation Bt = 0.0149(D2.H)1.0855. Carbon value was calculated as 50% of the total biomass. The results showed that after 17 years of planting Jati Mega, the stand density was 665 trees/ha, carbon storage was 59.98 Mg C/ha, and carbon uptake was 220.11 Mg/ha (CO2-eq). The total value of biomass, carbon stock, and carbon dioxide removal by Jati Mega stands at KHDTK Wanagama was in the medium category. The advantage of this research is for understanding the environmental services of jati Mega as a forest carbon stock. Information on forest carbon stock can be used as basic data for forest management as climate change mitigation.Keywords: superior teak, climate change mitigation, carbon accounting, environmental services

The mangrove ecosystem in Pangarengan Village, Cirebon District, provides benefits for environmental services, including as carbon sinks and stores. In estimating the carbon storage of mangrove forests, in general, allometric equations are used. Unfortunately, the allometric equations currently available are still composed of the stages of growth of saplings, poles, and trees. Thus, the purpose of this study was to develop an allometric model for seedlings in mangrove forests. The research was conducted in June 2021 in the mangrove forest of Pangarengan Village, Cirebon District. The equipment that used in the study were calipers, measuring tape, digital scales, and crop shears. Research materials were mangrove seedlings of Rhizophora mucronata, Avicennia marina, and Sonneratia caseolaris. The best allometric model in estimating dried weight biomass with base diameter predictor is Y = 35,013 Dp1,860 (R2adj = 0,873; SEE = 0,472) using tip diameter predictor is Y = 249.573 Du2,276 (R2adj = 0,524; SEE = 0,710). While the allometrics for estimating the carbon content of seedlings were Y = 5,835 Dp1,804 (R2adj = 0,831; SEE = 0,528) and Y = 35,750 Du2,107 (R2adj = 0,607; SEE = 0,805). Thus, the power allometric model with base diameter predictor was quite good in estimating dried weight biomass and seedling carbon content in the mangrove forest of Pangarengan Village.

Sleman Regency has determined bamboo as a superior non-timber forest product. Yellow bamboo (Bambusa vulgaris var. striata) is usually used for construction and craft materials. Hence, it is necessary to understand the characteristics of the culm. The study aimed to determine the predictor variables for the total internodes, and the distribution pattern of the length and bamboo wall thickness of the internodes on the yellow bamboo culms. The method used in this research was the method of destructive sampling for 30 bamboo culm samples. The samples were measured using a caliper for diameter at breast height and wall thickness, and measurement tape for the total length of the bamboo culm. For detail measurement, each sample was cut for each internode to be measured the length, diameter, and wall thickness of the internodes. The results showed that the predictor of diameter at breast height (dbh) is a predictor in estimating the total number of internodes on the culm resulting in an R2 of 0.631. While the total culm height as a predictor was able to explain the total number of internodes with an R2 value of 0.692. The length of the internodes pattern on the yellow bamboo culm from the bottom to the top side formed a bell curve. In the middle area of the culm, the length of the internode increased, but then it shrank back to the top side. The diameter and wall thickness patterns of the internode were non-linear. In addition, the predictors of diameter at breast height and total height are less accurate to explain the total number of internodes in yellow bamboo culms.

Introduction: Acute Coronary Syndrome (ACS) is a contributor to morbidity and mortality rates every year. The cause of death in ACS is a complication known as a MACE. However, it has not been known what can trigger the occurrence of MACE after post-ACS treatment. Objective: This study aimed to review and assess conditions that could predict the occurrence of MACE after treatment of ACS patients. Method: We conducted literature on articles between 2016-2021 with four databases: PubMed, Science Direct, CINAHL, and the search engine, namely Google Scholar. The design used is a scoping review. Five independent reviewers analyzed the inclusion and exclusion criteria. The researchers drew data from each article: author, year, region, purpose, design, related factors, and results. Furthermore, the researchers used PRISMA to compile the manuscript. There were 30 articles included in the analysis. One thousand articles were obtained through a basic data search based on the PRISMA flowchart, and after finding the manual, 30 studies were identified. Researchers selected relevant articles, namely predictors associated with MACE after treatment of ACS patients. Result: The results found that the predictors associated with MACE in ACS were comorbidities, adherence to hemodynamics medication, clinical parameters, the severity of atherosclerosis, increased cardiac disease assessment scores, and psychosocial disorder.

Melaleuca leucadendron Linn is one of Indonesia's most important non-timber forest products as a commercial essential oil. The aim of this research was to identify the variation of compounds in the essential oils of M. leucadendron when leaves were collected at different time from August 2017 to April 2018 at the Yogyakarta Forest Management Unit (FMU). The essential oils were isolated by steam distillation and analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 13 constituents were identified with major compounds, i.e. 1.8-cineole (57.8 to 76.0%), D(+)-limonene (4.40 to 12.1%), p-cymene (1.53 to 12.9%) and α-terpineol (4.98 to 9.98%). The results showed that the weather conditions in the early rainy season, with higher rainfall and flowering, were favorable for the production of essential oil (March) and increased the major compounds, especially from November to January (with the exception of α-terpineol, which was found to be higher in September). In contrast to these main compounds, α-pinene, β-pinene, and humulene are used as marker compounds to distinguish between dry and rainy seasons. In addition, it is also noted that the flowering stage affects the monthly variation of the major compounds.
