Based on the Round Table Conference between Indonesia and the Netherlands' representatives in 1949, West Papua will be delivered to Indonesia a year later. Nevertheless, the Dutch broke their promise to return West Papua to Indonesian sovereignty. The Dutch continued to insist on West Papua as their land and then increased their military presence in West Papua to prepare for defending the territory. Responding to this, initially, Indonesia made peaceful efforts, namely bilateral diplomacy within the Indonesian-Dutch Union ties, continued with trilateral diplomacy and diplomacy efforts using the Asian African Conference and United Nations organizations. However, Indonesian diplomatic efforts met with deadlock. Hence, another form of diplomacy, the military effort, has been displayed. This study's main aim is to review the 1962 military confrontation on salvaging West Papua in the analysis on war theory. Also, to prove that with sufficient military strength, the country will confidently step up to be the negotiating table winner. The Indonesian military strength at that time was playing a significant role as a deterrent effect. The research uses a qualitative descriptive phenomenology method, using data sources from several books and journals available. The result of the research shows that Indonesia absolutely needs a modern and more rigid military force to maintain its sovereignty, protect our Island and its natural resources. Without the deterrent effect of military power, Indonesia will be underestimated in international politics.

Coal mining business is now faced with various challenges such as export restrictions policy, an increase in value added products, and the decline in market prices of products. To be able to compete, mining companies are expected to increase productivity and efficiency and make continuous improvements in the production process. In the mining process, the availability of equipment and dump truck unloading tool will determine the sustainability of production that have an impact on productivity and efficiency. The purpose of this study was to optimize the production of coal mining in the context of the efficient use of equipment using the match factor, queues, and linear programming. The research location is in the area of the mining concession contractor KTD Corp is in the village of Embalut, District Tenggarong Seberang, Kertanegara Kutai Regency, East Kalimantan in October-November 2015. Unloading equipment used backhoe excavator is 5 units and 32 units of dump trucks. The simulation results match factor generated by the method optimal dump truck needs 26 units, while the queuing method and linear programming as much as 25 units of dump truck. The results of production optimization with linear programming method produced mining productivity of 1,208 BCM of overburden per hour with the optimum cost of $ 0,909/BCM.

Small war became popularly used in irregular warfare when a more considerable force dominated the opponent. Small wars but troublesome opposing forces are known as guerrillas. Since war architects popularized the guerrilla theory, it has also been frequently used in wars between forces. The psychological impact of most of the war's success can influence both state and group leaders to apply this model. It has been practiced and applied for a long time in various parts of the world until today. The very popularity of this model of warfare has prompted the author to produce an article that aims to compare the three guerrilla architects' frameworks from the point of view of a comprehensive strategy, tactics, and social aspects using the method of collecting data through document study. The results show that the framework of Mao Tse Tung, Vo Nguyen Giap, and Che Guevara about guerrilla warfare has its characteristics and perspectives.

Rural education is a short board of China’s education. It is of great significance to strengthen the construction of the teacher team in rural middle schools for Rural Revitalization in the new era. The problem of structural shortage of teachers, reflected by the phenomenon of “what biology teachers teach is not what they learned” in rural middle schools, is a key issue that has been existing for a long time in the development of rural middle school education in our country. It is also a key problem that must be paid attention to and urgently solved in the face of the new situation, new tasks and new requirements. In response to this phenomenon that caused by the decline of students and the loss of biological teachers in rural middle schools, the government needs to play a supporting role and the school leaders of rural middle schools should innovate their systems and concepts. What’s more, biological teachers should reflect on their hearts and have the educational feelings of being willing to develop the countryside. Only when the government, middle school leaders and biology teachers have formed an educational synergy, can we better solve that harmful phenomenon and promote the healthy and rapid development of rural middle school education.

In conventional economics, two types of macroeconomic policy i.e. fiscal policy and monetary policy are used to streamline the business cycle. This paper has examined the cyclical behavior of these variables over the business cycle of Bangladesh. The objective of this examination is to show whether policies (fiscal policy and monetary policy) in Bangladesh are taken with a motive to stabilize the economy or only to promote economic growth. In other words, it has examined whether the policies in Bangladesh are procyclical or countercyclical or acyclical. Hodrick Prescott (HP) filter has been used to separate the cyclical component of considered variables. Both correlation and regression-based analysis have provided that in Bangladesh government expenditure and interest rates behave procyclically, but money supply behaves acyclically over the business cycle. Besides, this paper has tried to identify the long-term as well as the short-term relationship between real GDP and the macroeconomic policy variables with the help of the Johansen cointegration test, vector error correction model (VECM), and block exogeneity Wald test. Through these analyses, this study has found that fiscal policy has a significant impact on GDP growth both in the short-run and long-run. In the case of monetary policy, although the interest rate has an impact on real output both in the short-run and long-run, the money supply has neither a short-run nor long-run effect on output growth.
