Indonesia is a country that has quite abundant coal reserves. Coal reserves are most widely spread in Kalimantan and Sumatra and several other areas. When the production of other fossil energy such as petroleum decreases, the use of coal energy sources actually increases. However, coal is also known as a dirty fossil fuel because its use has a negative impact on the environment. This needs to be paid attention to in order to develop innovations in using coal that are more environmentally friendly, so that they can also support the energy transition to achieve the Net Zero Emission (NZE) target. The energy transition is a process that must be carried out by countries in the world to reduce carbon emissions which can cause climate change and global warming. The agreement on the energy transition aims to increase the use of clean energy. The energy transition does not have to eliminate coal. However, coal requires innovation for more environmentally friendly use. One of the environmentally friendly coal utilization technologies is coal gasification. In the road map for the development and utilization of coal by applying environmentally friendly technology through coal gasification, one of which is the coal development program to produce methanol and DME.

In the realm of national security and sovereignty, Indonesia’s defense industry serves as a cornerstone, with its investment dynamics playing a significant role. This study offers a detailed analysis of these dynamics over the past decade, employing a comprehensive literature review methodology. It synthesizes information from a range of primary and secondary sources to unveil complex investment patterns, challenges faced by the industry, and the potential for growth and advancement. Scrutinizing the multifaceted factors that drive investment decisions, this study uncovers how geopolitical, economic, and security considerations, both globally and regionally, have influenced the industry. A notable finding is the strong correlation between an uptick in investments and advancements in technological innovation and industry autonomy. Despite positive developments, the study highlights ongoing challenges like stringent regulatory frameworks, a need for greater transparency, and the urgency of improving sector efficiency. A shift towards a more independent and technologically advanced defense industry in Indonesia is discernible, spurred by strategic investments. The study also sheds light on the pivotal role of foreign direct investment (FDI) in enhancing technological capabilities and catalyzing the growth of local industries via collaborative ventures. In terms of policy, the paper advocates for reformative strategies that reconcile national interests with the necessity of global economic integration. It suggests a suite of policy recommendations designed to promote a conducive investment environment, encouraging private sector involvement and international cooperation in alignment with Indonesia’s defense objectives. The conclusion asserts the feasibility of a sustainable and burgeoning defense industry through strategic and informed investment approaches. It calls for continued research and open dialogue among policymakers, industry players, and academics to effectively navigate the investment landscape of Indonesia’s defense sector, ensuring its alignment with broader economic goals.

Restorative Justice (RJ) involves the victim, perpetrator, victim/perpetrator's family and other parties that are resolved out of court. The parties, namely the perpetrator's family and the victim's family, agreed to resolve the problem by providing compensation. The crime of drug abuse has no victims or a victimless crime. Handling drug abuse, there is a common view and perception of law enforcers from the BNN, Police, Attorney General's Office and District Court, as victims and not criminals. In fact, there are still many law enforcement officials who treat drug users and abusers as criminals and not as victims. The existence of these differences in perception, makes the existence of confusion in handling using the RJ approach. The research uses normative juridical methods. The results of the research concluded that: There needs to be a guarantee of legal certainty in the handling of narcotics abusers, in the form of guidelines in the form of cooperation between the Supreme Court, the Attorney General's Office and the Police as law enforcers so that there is a common perception. The guidelines for handling narcotics abuse in handling RJ are expected to be a solution to the situation of prisons in Indonesia which are over capacity, with the rehabilitation of addicts expected to be free from dependence and for the community not to be restless.

This article discusses the phenomenon of religious intolerance in Indonesia through Cak Nur's perspective of pluralism. Pluralism, which is the main framework of this article, is the basis for revealing the complexity of the challenges faced by Indonesian society in understanding and appreciating religious pluralism. Cak Nur, a contemporary Islamic thinker and intellectual, provides a rich perspective on religious diversity and the importance of tolerance in religious dialogue. This article aims to highlight a number of factors that influence the emergence of intolerance in Indonesia. In this article the author uses a qualitative method, namely exploring and studying themes that are relevant to the theme of this article. Even though this country is rich in religious diversity, some groups still experience inequality and there are still tensions between religions. Within the framework of Cak Nur's pluralism, this article presents solutions based on dialogue and education from the perspective of Islamic teachings to overcome misunderstandings about the nature of religious diversity. This analysis also includes the role of social media, especially the Instagram account @jaringangusdurian in shaping public opinion regarding religious tolerance. By understanding Cak Nur's views, this article invites readers to understand and reflect on how Indonesian society can form a shared awareness of the values of pluralism, so that acts of intolerance in the name of religion no longer occur in the archipelago. This article uses Cak Nur's inclusive approach as a key step to reduce tensions and build a solid foundation for religious discourse.

Electrical energy is the most critical need in the defense sector to maintain state sovereignty. The floating PLTS in Cengklik Reservoir can be used as the main electricity source in the Adi Soemarmo Air Base building to support energy security and avoid black outs. Cengklik Reservoir has a total surface area of 253 ha. This research aims to find out what opportunities and challenges there are in developing a floating solar power plant project at Adi Soemarmo Air Base so that it can reduce dependence on fossil energy as a primary energy source. The research method used is descriptive qualitative. The research results show that if the utilization of floating PLTS is assumed to be 5% by the Minister of PUPR's regulations, the area of the Cengklik Reservoir where PLTS is installed is 12.65 ha, then a potential for floating PLTS of 14.80 MWp can be identified. This potential can support more reliable military operations. The challenge in building the floating PLTS project in Adi Soemarmo is that the distance between Cengklik Reservoir and Adi Soemarmo Air Base is 2.6 km, and regulations still need to be perfected in terms of permits.
电力是国防部门维护国家主权的最关键需求。Cengklik 水库中的浮动 PLTS 可用作 Adi Soemarmo 空军基地大楼的主要电力来源，以支持能源安全和避免停电。Cengklik 水库总面积为 253 公顷。本研究旨在找出在 Adi Soemarmo 空军基地开发浮动太阳能发电站项目的机遇和挑战，从而减少对化石能源作为主要能源的依赖。采用的研究方法是描述性定性研究。研究结果表明，如果按照 PUPR 部长的规定，浮动式 PLTS 的利用率假设为 5%，安装 PLTS 的 Cengklik 水库面积为 12.65 公顷，那么可以确定浮动式 PLTS 的潜力为 14.80 MWp。这一潜力可为更可靠的军事行动提供支持。在 Adi Soemarmo 建设浮动式 PLTS 项目面临的挑战是，Cengklik 水库与 Adi Soemarmo 空军基地之间的距离为 2.6 公里，在许可证方面仍需完善相关法规。

Biomass energy is recognized as having strategic potential in overcoming energy security challenges and its participation to reduce the impact of environmental problems. The research-purpose is to evaluate how implementing a biomass energy policy can support national defense and sustainability. Through the framework of the literature, this study describes the concept of biomass energy and examines its relation to national defense. Energy policy analysis and reversed with energy security in Indonesia are also obtained from the reflection of the literature. The results show that biomass energy can strengthen the security of a country's energy supply by diversifying energy sources and reducing dependence on imported fossil fuels. This will support the operational defense system in dealing with fluctuations in energy prices and supplies. The implementation of biomass energy also has the potential to increase national energy independence, reduce the risk of energy supply disruptions, and strengthen national resilience. Utilization of biomass energy also contributes to improving climate change and negative environmental impacts. With the right technology, reductions in greenhouse gas emissions can be achieved, supporting environmental sustainability goals and securing the future of national defense

The research explores advancements in muzzle brake designs for lightweight rifle firearms, aiming to control recoil during firing. The SL Rifle 41 from World War II serves as a historical example, highlighting challenges such as gas escaping near the muzzle, rapid cooling, and piston fouling. The gas expansion difference between the barrel and piston poses operational issues. The firearm shooting process involves high-temperature, high-pressure propellant gas released through the muzzle brake, creating a complex 3D instability problem. The shockwave from the muzzle blast significantly impacts the muzzle brake surface. Modern SL Rifle designers seek to enhance projectile muzzle velocity and After-Action Gas Powder (AAPG) simultaneously, addressing recoil energy through opposing impulses. The research employs a literature review method, analyzing concepts, theories, and findings. The SL Rifle's operational mechanism uses a direct gas impingement system, offering simplicity but accumulating carbon particles. Muzzle brake models feature a primary body and baffles strategically designed for gas dispersion and recoil reduction. Detailed examination of brake muzzle/barrel material objects and established muzzle brake models illustrates engineering considerations, enhancing understanding of design and characteristics. The comprehensive design aims to optimize performance, durability, and shooting stability while minimizing wear associated with carbon buildup. In conclusion, the evolution of muzzle brake design contributes to enhanced firearm performance, ensuring smoother firing, reduced recoil, increased accuracy, and control. Ongoing advancements cater to diverse user needs in military, law enforcement, and civilian contexts, reflecting a commitment to improving firearm technology.
