The operation strategies are key points that can influence the annual total energy efficiency, energy saving efficiency and economic benefits of BCHP systems. This paper mainly aims at establishing the model about how to realize several typical operation strategies of BCHP systems based on gas engines, such as operation following the power load and operation following the heating load. Also, in a specific project, operation strategies always depend on the load feature and the government policy and the price of power and etc. This paper includes methods about how to choose the operation strategies reasonably.

Cross-border migration between Timor Leste and Indonesia continuously occurs and becomes an important public problem, although the government of Indonesia firmly implements policy to restrain it. This research examined the influence of government policy on individual decision of Timor Leste people to migrate across the border to enter Indonesia. It used quantitative method to analyse causal correlation between government policy and individual decision to migrate across the border of the two countries. Research subjects amounted to 165 including Timor Leste migrants, immigration and security officials in the cross border points. Data obtained from questionnaire were analysed through descriptive statistic, Pearson correlation and simple linear regression techniques. This research found that passport/visa service is very expensive, the implementation of regulations on immigration services is very strict, while the providing of safe atmosphere, fair security and immigration service to migrants is at high level. Social, cultural and economic benefits being obtained in Indonesia are very important criteria, while clarity of objective, commitment to attain the objective, expenses of migration, security assurance, availability of transportation tools and infrastructures are important criteria that determine individual decision to migrate across the border of the two countries. This research also found that government policy has weak correlation, but have positive influence on individual decision to migrate across the border of the two countries, and its influence is 12.9%. The government of Indonesia needs to improve the quality of its public policy to manage the cross-border migration effectively and efficiently.

The article studies the system of pre-conditions that caused the onset of the uniat clergy’s movement towards Orthodoxy in the Russian Empire in the beginning of the 19th century. The author comes to the conclusion that the tendency of the uniat clergy going back to Orthodoxy was the result of certain historic conditions, such as: 1) constant changes in the government policy during the reign of Emperor Pavel I and Emperor Alexander I; 2) increasing latinization of the uniat church service after 1797 and Latin proselytism that were the result of the distrust of the uniats on the part of Roman curia and representatives of Polish Catholic Church of Latin church service; 3) ecclesiastical contradictions made at the Brest Church Union conclusion; 4) division of the uniat clergy into discordant groups and the increase of their opposition to each other on the issue of latinization in the first decades of the 19th century. The combination of those conditions was a unique phenomenon that never repeated itself anywhere.

Palm oil industry in Indonesia has been growing rapidly. But, unfortunately the growth is only effective on upstream industry with low value products, such that potential downstream value added are not explored proportionally. The government is therefore in the process of developing an appropriate policy to strengthen the national palm oil downstream industry. This paper proposes that an approriate policy for developing palm oil downstream industry could be derived from the maps of value chain and existing technology capability of the industry. The result recommends that government policy should emphasize on the supply of raw materials, infrastructure and utilities, as well as developing the missing value chain industry, especially ethoxylation and sulfonation.

Penelitian ini bertujuan untuk mengkaji daya saing komoditi kakao di Sulawesi Tengah dan melihat peran pemerintah dalam meningkatkan daya saing komoditi kakao. Data primer berasal dari observasi, wawancara dan kuesioner, sementara data sekunder berasal dari instansi terkait. Metode analisis menggunakan Policy Analysis Matrix (PAM) dan analisis sensitivitas. Penelitian ini menemukan bahwa nilai PCR Kabupaten Parigi Moutong 0,589 dan Kabupaten Sigi 0,396. Sedangkan nilai DRC Kabupaten Parigi Moutong 0,387 dan Kabupaten Sigi 0,319. Hal tersebut mengindikasikan bahwa usahatani komoditi kakao di Sulawesi Tengah memiliki daya saing, namun tidak menguntungkan secara ekonomi karena Sulawesi Tengah menghasilkan biji kakao yang tidak difermentasi akibatnya petani menerima harga rendah. Berdasarkan hasil analisis, pemerintah belum memberikan proteksi terhadap harga biji kakao dalam negeri melalui harga referensi biji kakao sehingga harga biji kakao didaerah penelitian masih tergolong rendah jika dibandingkan dengan harga di pasar internasional. Sementara terhadap input, pemerintah telah memberikan kebijakan subsidi kepada petani, namun implementasinya masih perlu perbaikan terutama terkait penyaluran dan pengelolaan bantuan agar merata. Kajian ini merekomendasikan masih diperlukan kebijakan pemerintah baik terhadap input maupun output untuk meningkatkan produktivitas, menurunkan biaya produksi dan menaikkan harga jual biji kakao, sehingga dapat meningkatkan daya saing biji kakao. The purpose of this study is to assess the competitiveness of cocoa in Central Sulawesi and to investigate the role of government in improving the competitiveness of cocoa. The primary data were generated through observation, interviews and some questionnaires. The secondary data were obtained from the agency or the institution related to the research. This study uses the Policy Analysis Matrix (PAM) and sensitivity analysis. The study found that the PCR value for Parigi Moutong district was 0.589 and Sigi district was 0.396. While, the DRC value for Parigi Moutong district was 0.387 and Sigi district was 0.319. This indicates that cocoa beans farming in Central Sulawesi has competitiveness, but not economically beneficial because Central Sulawesi produces unfermented cocoa beans consequently farmers receive low prices. Based on the results of the government's impact on output analysis, the government did not provide protection for domestic cocoa seed prices through the reference price of cocoa beans, consequently the price of domestic cocoa beans, particularly in the research area, was relatively low compared to the price of cocoa beans at the international market. Seen from the government policy on inputs, the government have provided subsidies to farmers but they need to improve the distribution and management of aid to be evenly distributed. It is necessary to set up good government policy on inputs and outputs in order to increase cocoa seed productivity, decrease production cost and increase the price which simultaneously can improve its competitiveness in the research location.

The aim of this study is to investigate the factors influencing the entrepreneurial success of rural women entrepreneurs in Bangladesh. Non-probability sampling specifically convenience sampling is used to draw the sample and data is collected using the self-administered survey. Regression analysis and descriptive statistics are used to analyze the data. The study discloses that motivational factors, government policy and financial support have significant influence on the rural women entrepreneurial success in Bangladesh. Due to lack of suitable training and proper development as well as ICT knowledge, the rural women of Bangladesh could not accomplish the achievement. Half of the total populations of Bangladesh are female and most of them live in rural areas. Therefore, the government and the policymakers in Bangladesh should develop the potential of rural women entrepreneurs by providing development facilities, proper training, and ICT knowledge.

Energy efficiency and renewable energy are the two main research topics for sustainable energy. In the past ten years, countries around the world have invested a lot of manpower into new energy research. However, in addition to new energy development, energy efficiency technologies need to be emphasized to promote production efficiency and reduce environmental pollution. In order to improve power production efficiency, an integrated solution regarding the issue of electric power load forecasting was proposed in this study. The solution proposed was to, in combination with persistence and search algorithms, establish a new integrated ultra-short-term electric power load forecasting method based on the adaptive-network-based fuzzy inference system (ANFIS) and back-propagation neural network (BPN), which can be applied in forecasting electric power load in Taiwan. The research methodology used in this paper was mainly to acquire and process the all-day electric power load data of Taiwan Power and execute preliminary forecasting values of the electric power load by applying ANFIS, BPN and persistence. The preliminary forecasting values of the electric power load obtained therefrom were called suboptimal solutions and finally the optimal weighted value was determined by applying a search algorithm through integrating the above three methods by weighting. In this paper, the optimal electric power load value was forecasted based on the weighted value obtained therefrom. It was proven through experimental results that the solution proposed in this paper can be used to accurately forecast electric power load, with a minimal error.
