The energy transition toward Net Zero Emission by 2060 hinges on the renewable energy power plants in Indonesia. Good practices in several countries suggest a peer-to-peer (P2P) energy trading system using blockchain technology, supported by renewable energy (solar panels), an innovation to provide equal access to sustainable electricity while reducing the impact of climate change. The P2P energy trading concept has a higher social potential than the conventional electricity buying and selling approach, such as that of PLN (the state-owned electricity company in Indonesia), which applies the network management concept but does not have a sharing element. This model implements a solar-powered mini-grid system and produces a smart contract that facilitates electricity network users to buy, sell, and trade electricity in rural areas via smartphones. This study aims to measure the stakeholders’ perceptions of the peer-to-peer (P2P) energy trading model using blockchain technology in the Gumelar District, Banyumas Regency, Central Java Province, Indonesia. The stakeholders in question are representatives of Households (producers and consumers), Government, State Electricity Company (PLN), Non-Governmental Organizations, Private Sector and Academician. Measurement of perception in this study used a questionnaire approach with a Likert scale. The results of filling out the questionnaire were analyzed using four methods: IFE/EFE matrix; IE matrix; SWOT matrix; and SPACE matrix to assess the results and their suitability to each other. The results of the stakeholder perception assessment show that there are 44 internal factors and 33 external factors that can influence this model. We obtained an IFE and EFE score of 2.92 and 2.83 for the internal and external results using the IE matrix. These place the model in quadrant V, meaning the P2P model can survive in the long term to generate profits. Based on the SWOT analysis results, this model is located at the coordinate point −0.40, 0.31, placing it in quadrant II. This means that the P2P model is in a competitive situation and faces threats but still has internal strengths. Based on the SPACE matrix, stakeholder perception states that the P2P model is at coordinate point 1, −0.3. This shows that the P2P model has the potential to be a competitive advantage in its type of activity that continues to grow. In conclusion, our findings show that stakeholders’ perceptions of P2P models using blockchain technology can be implemented effectively and provide social, economic, and environmental incentives.

Disasters have direct consequences that affect human life and the environment. Vulnerability to disasters happens due to a lack of proper disaster management, various environmental impacts, or people’s negligence. The amount of losses in every catastrophe depends on the resilience capacity of the community against disasters. The Indonesian National Military (TNI) as the nation’s guardian and defense component has two main tasks, namely (1) Military Operations for War (Operasi Militer Perang/OMP) and Military Operations Other Than War (Operasi Militer Selain Perang/OMSP). In this case, TNI is carrying out the MOOTW duties, based on RI Law Number 34 of 2002 which states that the TNI is a force that helps the government in handling disasters. TNI plays a significant role in Military Operation Other Than War (MOOTW) that includes leading in disaster management, increasing organizational capacity and operational management in supporting disaster management, boosting cooperation, education and training on disaster management, providing facilities and infrastructure including budget planning and support from the top command of the central and regional governments. This paper is using the Analytic Hierarchy Process (AHP) by determining the goals, criteria, and the overall sub-criteria for each of the MOOTW criteria/factors and considering options for increasing the budget or cooperation. The results are then used as a reference for decision-making in handling the disasters.

The success of a research is highly dependent on the method adopted, especially research related to dangerous and expensive matters which will certainly require special handling in the development or maintenance steps. One of them is research related to space technology such as aviation and rocketry technology, which is very dependent on the design model of the flying vehicle and, in general, will always use simulation to ensure that the entire system being built is carried out safely and can be implemented properly according to plan. In the development of the prototype flying vehicle, especially the development of the avionics and flight control system, the vehicle will go through sequential simulation steps from Software in the Loop Simulation (SILS), Hardware in the Loop Simulation (HILS), and Ready-to-Fly System (RTFS). In this paper, the simulation steps will be described with the intention of facilitating integration and testing of each sub-system being developed, testing the control strategy applied or eliminating bugs if something goes wrong. In the end, with a series of flying vehicle simulations, it can be developed quickly and cost-effectively, including saving human resources.

Globalization has produced a complex strategic environment, posting a dynamic threat to national security. In this case, a strategic form of leadership becomes important in running a country, especially in the context of national defense. The purpose of this article is to reveal the bureaucratic leadership style that can function as a form of strategic leadership in national defense policy. Based on the literature study method, it was found that a transformational bureaucratic leadership model can be a form of strategic leadership in National Defense Policy in Indonesia. Leadership transformation is carried out through competency development in the form of superior leadership abilities and attitudes that are in accordance with the needs of the times. With this competence, bureaucratic leaders are expected to perform their leadership duties proportionately and handle any problems that may arise in their organization. The guardian leadership that can motivate, encourage, and serve as an example for their subordinates will be crucial in the realization of the bureaucratic leadership style to support national defense policy. Characteristics of a leader with honor, creativity, discipline, motivation, anticipation, guardianship, spirit of nationalism and patriotism, and integrity will have a positive impact on the National Defense Policy. By combining breakthroughs with a type of continuous control, the division of specific tasks at specific organizational level, and Millennial HR’s involvement, a leadership approach will be able to explore the potential to produce organizational performance far above what has been achieved so far, in particular in Indonesian National Defense policy management.

Since the end of World War II, the use of nuclear power as a weapon of war has been criticized for causing the deaths of up to 55 million people. Then there was a shift in the use of nuclear power from military to peaceful purposes, such as economic goals, and many countries built nuclear reactors as an alternative to conventional fuels. In addition, nuclear power can also serve as a very strong deterrent factor to prevent open war. Indonesia's geographical position is currently surrounded by countries that own nuclear reactors, such as North Korea, Iran, Russia, China, and India, followed by the formation of the AUKUS alliance of Australia, the United Kingdom (U.K.), and the United States (U.S.). With the geopolitical conditions and escalation in the region, Indonesia should take precautionary measures to avoid a nuclear war in the region. This study aims to identify the best anticipatory steps that can be taken by conducting in-depth Focus Group Discussions (FGD) and extracting data using questionnaires from ten academics, diplomats, nuclear experts, military personnel, and professionals, which results in several alternative options. The option is then analyzed to identify which is the best by using Analytical Hierarchy Process (AHP) method and confirmed with Strengths, Weaknesses, Opportunities, and Threats (SWOT ) Analysis. Based on the findings of the analysis, the sequence of anticipatory steps that must be taken is as follows: 1) through diplomacy; 2) through the strengthening of defense equipment; 3) participation in certain alliances, either temporarily or permanently, and 4) building a national nuclear capability as a deterrent. As a result, diplomacy remains the primary option for resolving the region's escalation

Kaltim presumably experiences an energy paradox, where the energy system is unreliable and unsustainable, despite energy-rich. This study presumes that the paradox is caused by the ‘ill-advised energy policy’ shown by ‘energy-area incompatibility’ that is exacerbated by the ‘energy-rich syndrome’ (a mindset of feeling secure due to energy-abundance leading to a wasteful behavior). This study investigates the indication of the syndrome in Kaltim energy policy by first investigating ‘the incompatibility’ and its impacts by examining Kaltim’s geographical characteristics, energy potential, population-distribution, electricity system, and infrastructure. Also, the impacts of retaining the syndrome through cost analyses. This study finds the incompatibility between energy-sources utilization and geographical characteristics, by conducting a descriptive method with data collection and analyses. Kaltim is forest-dominated with scattered-population, suitable with an off-grid system. However, the electricity development is mostly on-grid, fossil-based designed, explaining the difficulties of electrifying the entire Kaltim, although electricity is surplus. While off-grid should be applied to NRE, the massive use of diesel-gen-sets shows wasteful behavior. By conducting a linear-regression method, this study finds that Kaltim’s electricity consumption (indicating the infrastructure sufficiency) is lower than it should be, given its incredible economic performance. The incompatibility causes infrastructure insufficiency. The cost analysis finds that the massively-used fuel oil is the most expensive. The subsidy would be around 0.003%-0.275% of Kaltim GDRP or 17 billion-1.55 trillion IDR. As the new Capital location, NRE is a must for Kaltim. To conclude, NRE utilization is very low, although its potential is huge, and Kaltim’s forested characteristics suit it. NRE only covers 3% of Kaltim’s electricity, while the potential (hydro alone) is more than 6,900MW. The incompatibility causes an unreliable electricity system, although electricity is surplus. Following Kaltim’s geographical characteristics, NRE should be optimized. This study intends to aware the policy-makers of the syndrome, thereby develop a ‘proper energy policy’.

The energy security principle demands the fulfillment of availability, acceptability, affordability, accessibility, and sustainability. Under the financial constraints, it is very challenging to achieve. As a result, immediate decisions, often only based on the lowest cost neglecting the overall impacts, are taken. This study aims to reveal the energy provision dilemma through a literature review method and simple calculation analysis. This study intends to exemplify how to conduct an equitable analysis by comparing wind and coal power plants’ impacts from the economic, environmental, and social perspectives. This study finds that the mutually complement characteristics of NRE (New and Renewable Energy) and non-NRE (fossil energy sources) raise a dilemma in selecting the energy source, where the financial constraints exaggerate the dilemma. The study also finds that the electricity generating cost of coal is cheaper than wind, but the external costs turn over the result. Coal damages the environment more than wind, but the impacts are often neglected, and society bears the cost. A simple adsorption method could minimize the impacts, but it depends on the producers’ willingness to conduct, which eventually by the consumers’ willingness to pay the higher price. In the social aspect, both power plants have relatively more equal indirect impacts, but coal’s direct impacts are more detrimental than wind. While an energy source may excel the other, considering the specific circumstances is a must. Financial constraints aggravate the developing countries’ dilemma between achieving energy security or fulfilling the basic needs and pursuing economic growth.

There are currently two fiscal regimes designated for resource allocation in Indonesia’s upstream oil and gas industry, the Production Sharing Contract Cost Recovery (PSC) and Gross Split. The Gross Split in the form of additional percentage split is designed to encourage contractors to implement Enhanced Oil Recovery (EOR) in mature fields. Low Salinity Water Injection (LSWI) is an emerging EOR technique in which the salinity of the injected water is controlled. It has been proven to be relatively cheaper and has simpler implementations than other EOR options in several countries. This study evaluates the LSWI project’s economy using PSC and Gross Split and then to be compared to conventional waterflooding (WF) project’s economy. There are four cases on Field X that are simulated using a commercial simulator for 5 years. The cases are evaluated under PSC and Gross Split to calculate the project’s economy. The economic indicators that will be evaluated are the Net Present Value (NPV) and sensitivity analysis is also conducted to observe the change of NPV. The parameters for sensitivity analysis are Capital Expenditure (CAPEX), Operating Expenditure (OPEX), Oil Production, and Oil Price. It is found that LSWI implementation using Gross Split is more profitable than PSC. The parameters that affects NPV the most in all PSC cases are the oil production and oil price. On the other hand, in Gross Split cases, the oil production is the parameter that affects NPV the most, followed by oil price. The novelty of this study is in the comparison of project’s economy between WF and LSWI using two different fiscal regimes to see whether Gross Split is more profitable than PSC on EOR implementation, specifically the LSWI at Field X.

This study aims to reveal the challenging sustainability within Indonesia’s energy provision by studying the electricity generating cost (GC) formation, externalities’ effect, and current Indonesia’s electricity and budget condition. In studying GC formation, two variables thought to have remarkable influence are fuel price (represented by Fuel Cost/FC) and operating time, which indicates the power plant’s type (represented by Capacity Factor/CF). The regression results indicate that CF has a greater impact on GC than FC; GC increases as FC increases but decreases as CF increases. FC contributes by 10%-86% of GC, subject to fuel prices and CF. Since coal is the cheapest, GCCoal < GCGas < GCDiesel, but internalizing the externalities triples the GCCoal and doubles the GCDiesel. However, its internalization is challenging as it affects the producers’ and consumers’ welfare. Sustainable energy provision is challenging due to two factors. First, there is a dilemma between applying sustainability principles and providing energy immediately. The fastest route, which is the lowest price orientation, is preferable, indicated by coal domination in the electricity mix. Second, sustainability is not the priority yet, indicated by the environment programs is outside the top ten priority development programs.

This study aims to prove the truth of national resilence concept by using deductive phenomenological interpretive qualitative methods with epistemology of geostrategy as a main objective. Popper’s falsification test is intended to gather evidence on which the geostrategic peripheral is applied to the national resilience concept, rather than reject the conception. The required data includes the national resilience concept and an epistemology of geostrategy to explain geostrategic realities in a sistematic hierarchy, using historical documents, scientific publications and also interviews. This study has shown that the national resilience concept sits outside the geostrategic periphery, despite some evidence of geostrategic validity. The evidence indicating the applicability of geostrategy includes (1) Formulation of national objectives and; (2) Consideration of geography and geopolitical conditions

This article utilizes the Analytical Hierarchy Process (AHP) method to decide how to choose an effective weapon system for the A2/AD (anti-access/area denial) strategy at the Sunda Strait, Indonesia's strategic choke point. The main discussion is limited to selecting the types of weapon systems considered effective in implementing A2/AD at Indonesia's strategic choke points. The next step is to decide which primary, secondary, and alternative criteria are the most important. Each of these will then be put together mathematically by measuring consistency using the Consistency Index (CI), the Consistency Ratio (CR), and the Consistency Hierarchy, which is the ranking as the result of the analysis. This method resulting in a weight for the navigation criteria of 66%, projection of 19%, and operability of 16%. Furthermore, in conclusion, the order of the best weapon systems is RBS15 MK4 with a weight of 66%, Brahmos II at 18%, and Neptune 360ST at 16%. [ABSTRACT FROM AUTHOR]

One of the main issues facing the Government in Malacca Strait is the security and safety issue, which threatens the users of sea transportation service and potentially interferes with the business operation. In fact, most of the international distribution lines pass through the Malacca Strait, making it the busiest strait in the world. On the other hand, the high cost of maintaining security and safety in the area burdens the government. Hence, this research aims to develop a strategy in handling the sea transportation system to achieve the equilibrium between economic efficiency and the government's effectiveness in maintaining the security and safety of the shipping traffic in Malacca Strait. This study is a problem solving-based research using Soft System Methodology. As a result, the integrated piloting strategy has been developed as a recommendation to be implemented. With this strategy, the ships that pass through the Malacca Strait are advised to adopt integrated piloting. The pilots and the security guards would be on board and safely and securely help the ship pass through the Malacca Strait. By that, safety and security would be guaranteed, and the business objectives would be achieved. Keywords: malacca strait, maritime study, sea transportation, soft system methodology

This article analyzes the advancement of defense capabilities in the future. In carrying out this analysis, first, a mapping of national defense threats is conducted. Nowadays, there is a change in the way of looking at future defense threats which no longer see conventional wars but the defenses needed tend to adapt to technological developments and globalization which is growing rapidly. Qualitative methods are used as an approach in this study by strengthening the literature review as a reference and collecting research data. The results showed that the national defense threat was formed into military, non-military and hybrid threat groups. To deal with these threats, traditional defense is not enough. A total people's defense and security system that involves the main components, reserve components and supporting components is needed to form a superior system capable of dealing with all kinds of threats. In addition to the defense system, the innovation of war weapons technology is also very much needed which is supported by superior human resource competencies. [ABSTRACT FROM AUTHOR]
