Venu Island Wildlife areas, Kaimana-West Papua is one of the places for nesting of Chelonia mydas, Linn. 1758/Green Turtles/Jelepi. Thus, This study was conducted to identify the physical characteristics of Jelepi nesting in the Venu Island Wildlife areas, Kaimana-West Papua. Based on the analysis of the main components bi-plot of the physical characteristics of the main factors were found nesting and landing Jelepi, among others: Temperature sand at depth ≤30 cm (X ̅=27.42 C ± stdev 0,47 C), lighting at 11.0013.00 (X ̅=229.25lux ± stdev 326.50lux), building areas (X ̅=3.18 m2 ± stdev 16,74 m2), medium sand fraction in depth ≤30 cm (X ̅=39.86 ± stdev 16.11), and the number of holes nesting Jelepi (X ̅=1.52 nest ± stdev 1.12 nest).

Most of the urban pollution is the result of carbon dioxide (CO2) emission from human activities. This research identified CO2 emission and absorption in Bogor, and also the alternatives to solve the emission problem by system model and simulation. CO2 emission and absorption system model was created using software Stella 9.0.2 based on loss-gain emission concept for 30 years prediction. Human activities that contribute to CO2 emission are transportation, industries, energy consumption such as fuel or electricity, house hold waste, and farms, while the decrease factor is green open spaces as CO2 sequester. The alternatives to solve emission problem in Bogor is created based on green city concept by including the environmental aspects in every urban activity. The result of this research, the CO2 emission of Bogor reached 20.027.878 tons and the absorption reached 93.843 tons in 2042. Combined mitigation alternatives in several sectors could reduce CO2 emission by 2.797.667 tons in 2042 and CO2 emission could be neutralized by reforestation in 2036.

Protected Forest Management Unit (PFMU) of Solok is one of 120 FMU Model that has been set by the government through Ministry of Environment and Forestry (MoEF). Community settlements (Nagari) were around and inside the FMU. Additionally, the existence of the FMU as a new institution in forest management cause different interpretation of the various stakeholders. The objective of this research was to identifying stakeholders and their interest and analyzing the patterns of relationship of stakeholders involved in the management of PFMU Solok. This research was conducted based on stakeholder analysis and social network analysis. Stakeholders involved in management of PFMU Solok have diverse interests and power. There were 22 stakeholders identified, in which 2 were classified as key players, 10 as subject, 4 as context setter, and 6 as crowd. Interaction pattern of stakeholders in the form of information flow was not spread evenly. The result shows that there were many stakeholder in the management of PFMU Solok. Multistakeholder forest management can be an alternative management model to integrate interests of stakeholders and equally distribute information.

The management of a protection forest often faces a dilemma between the importance of conservation and the importance of the needs of the local people in the area. Managing the area will on’t be so effective and disturbed if there is only minimal participation and insufficient support in interaction from the local people. Various factors of heterogeneous people will influence the form of interaction that occurs between the people and the area. The aim of this study is to know and measure the participation of the local people in managing the protection forest and to analyse the characteristics (both individual and organizational) that influence the level of participation collectively in preserving the protected forest area. This research is designed as a survey research having the character of a descriptive co-relationship between the variable dependent i.e. Community participation and the variable of individual and organizational characters as a heterogeneous factor in protection forest area. This research population is the active community who manage the land (dusung) around the protection forest area in Gunung Nona (HLGN) in Ambon. Data analyses used tests the technical Chi square and its participation level test the co-efficient of the contingency. Results show that the characteristics (both individual and organizational) that have a close connection and influenced the level of participation in preserving the HLGN area are their knowledge about the protection forest, the scope of the authority of dusung land, the status of ownership of the dusung, the period of involvement in the organization and the relationship between the organizer and the public members in the organization. People’s participation in managing the HLGN is based on the perceived benefits and how they manage the dusung depends on their own character or morale. Key words: Participation, Heterogeneous, Dusung.

Glass fiber/epoxy composite was developed and used widely in manyapplications. Development on fiber and matrix of composite material was done to improve itsproperties. Improvement of the composite’s matrix can be done/by adding a modifier. Silicone resinis one kind of modifier that can be added to epoxy to improve its properties. Silicone resin willimprove the thermal stability of epoxy, but the effect on mechanical properties, especially whencombined with glass fiber, has not been done. In this study, a composite of glass fiber/epoxy with 0,10, 20, and 30 weight-% silicone resin addition was tested by compressive and flexural loadingmethods. Compressive strength and maximum strain tend to decrease with the increase of siliconeresin added. The highest compressive strength and strain were reached by a glass fiber and epoxycomposite without any modification at the value 240.63 MPa and 0.5%. Flexural strength willdecrease, but maximum strain will increase when more silicone resin is added to the matrix on theflexural test. The biggest flexural strength at 293.73 MPa was possessed by the composite withoutfurther modification, and a maximum strain of 5% was owned by the composite with 20% and 30%silicone resin addition.

Company value is important because it influences the company's survival in the future. Many variables can influence company value, such as disclosure and capital structure management. Disclosure is carried out to provide information to stakeholders about the company, one of which is disclosure of Corporate Social Responsibility (CSR) which is a responsibility in terms of economic, environmental and social aspects. Capital structure management is carried out to achieve a balance between liabilities and equity so as to maximize company value. This research aims to determine the influence of Corporate Social Responsibility, Profitability and Capital Structure on Company Value in the current Covid 19 pandemic era. This research uses quantitative descriptive research. The population and sample in this study are pharmaceutical companies listed on the Indonesia Stock Exchange for the period 2018 - 2022. The data used is secondary data from annual financial reports on the Indonesia Stock Exchange. This research uses data analysis techniques such as multiple regression analysis and SPSS as tools to process and test data. The results of this research show that partially CSR has no significant effect, ROE has a significant effect and DER has no significant effect on company value. Meanwhile, simultaneously CSR, ROE, and DER have a significant effect on company value.
