The rapid economic development in Bengkalis District has reported disrupted environmental balance. Such as mangrove forest damage, due to the intensification of wetland conversion, which is based on the emergence of industrialization. Implementing community-based mangrove forest management (CBMFM) with a carbon credit system is potential way to reduce the degradation. This management model also inline to support the achievement of sustainable development goals (SDGs). This study objective is aims to formulate a CBMFM strategy for CO2 emission reduction which registered as carbon offset project. The research design was descriptive qualitative, focusing to identify current and best management aspect of mangrove ecosystem which meet carbon project standard. The information used was secondary data that collected from relevant literatures. The formulation of sustainable CBMFM strategy was established based on the gap analysis between existing management versus expected sustainable ones. The analysis results showed that the current management was yet optimal, due to the lack of sustainable management dimensional practices, include: human, natural, and financial resources. The strategy to reduce current management gap as follows: (1) Increasing the capacity of human resources for managers and institutions; (2) Application of collaborative management; (3) Accountable budgeting; (4) Preparation of an integrated management plan; and (5) Technology management. The research result recommended as one of a reference for policymakers, in order to formulate sustainable mangrove forest management.

This research focuses on developing Building Information Modelling (BIM) libraries and guidelines for Islamic Architecture (IA). It aims to enhance design and reduce the time and cost for projects that utilize Islamic-styles of architecture. The main objective of Part 2 is to develop BIM-driven (BIM-IA) libraries and guidelines for Islamic Architecture components that are organized chronologically based on Islamic Architecture history. The resultant BIM-IA is intended to be an organized Islamic architecture database that includes the myriad of Islamic building characteristics and styles. The proposed BIM libraries will include most Islamic Architecture forms, styles, characters, construction methods, structural elements, and the various architectural components that can be used projects. Application of this library is demonstrated in an example that designs a mosque. This example shows how the BIM-IA will assist designers when making decisions about mosque design and function while also demonstrating how valuable time and resources can be conserved when searching for optimum design choices. The research strives to advance building informatics by developing parametric digital components and guidelines of Islamic Construction.

One of the ways to reduce CO 2 emissions in Pelalawan District is potentially by Indigenous-based Forest management (IBFM) focusing on ecosystem services. This study aims to develop a roadmap of sustainable forest management to support the achievement of sustainable development goals (SDGs), especially the 13th Goal: mitigation and adaptation to climate change. The research was conducted in Langgam Village, Pelalawan District, Riau Province, Indonesia. The research method used was qualitative descriptive interpretative. The relevant secondary data were collected from various sources. The results showed that the indigenous peoples in Langgam Village had maintained the natural forest both inside and outside the forest area. However, the current forest management has not been optimally supported by the stakeholders to be registered as a carbon offset project. The strategy to achieve CO 2 emissions reduction is by facilitating indigenous people to improve the dimensions of current forest management into a conservation business movement with ecosystem services products to support low carbon development that is integrated with regional development plans and in line with global carbon market standards. The study results are recommended as one input for policymakers to achieve the SDGs, especially on climate change mitigation and adaptation through community-based forest management.

Pelalawan District has several natural attractiveness and indigenous knowledge potentially to be developed as ecotourism. The community-based ecotourism management (CBEM) by utilize indigenous knowledge as a part of tourist attractions is one of ways to improve environmental ethics and achieve sustainable development goals (SDGs). This paper was prepared to examine the potential of indigenous CBEM in Pelalawan District. Secondary data was used compiled from relevant literatures of previous research or provided by authorized agency. The data analysis method carryout by comparative descriptive interpretative qualitative analysis. It identified the gaps between the existing condition of CBEM versus standards. A conceptual framework and CBEM strategy were arranged to eliminate current management gaps. The analysis result shows that current indigenous CBEM yet optimal. It shows by the lack of management dimension aspect, includes: tenurial license, local ecotourism norm, land use planning, marketing, supporting regulation, environmental education, management capacity, infrastructures development, and business incentives. The strategies to eliminates CBEM gaps, as follows: (1) Integrated planning; (2) Feasibility analysis of village own enterprise (BMUDes); (3) Capacity development of staffs and community; (4) Enhances marketing system; (5) Accountability of management; (6) Integrated environmental education curriculum; (7) Continuous improvement; and (8) Supporting regulation. The research result was recommended as one of references for policy makers to develop indigenous CBEM planning for strengthen environmental ethics and SDGs achievement as integrated manner. Authors recommend to future researchers would be expanded the scopes of the literatures and collect primary data for its accuracy improvements.
