The objective of this reseach are to: (1) analyze the factors affecting human development index and household expenditures for health, education and others, (2) predict the impacts of government expenditure policy in the field of education, health, and infrastructure on human development index in Central Java. The model was built using econometric approach in the form of a system of simultaneous equations, including five blocks i.e. government's revenue, expenditures, input, output, and performance. The system of simultaneous equations consisted of 26 equations (19 structural equations and 7 identity equations). The estimation method used Two Stage Least Squares with SYSLIN procedure. Prediction simulation used the stepwise Autoregressive method. The model simulation used Newton's method and SIMNLIN procedure. The results of policy simulation concludes that the combination of the increase in government expenditure for education and infrastructure lead to better performance in increasing income per capita, disposable income and HDI compared to the combination of the policy of the increase in government expenditure for education and in both municipalities and district, but municipalities receive greatest impact compared to the district.

The research aims to analyze the influence and impact of educational, health, and infrastructure expenses on the employment of workforce (from agricultural, industrial, services sectors) and poverty in Central Java. The model was built by using an econometric approach in the form of a system of simultaneous equation model consisting of six blocks (human capital, inputs, outputs, revenues, expenditures and social welfare) with 33 equations (24 structural equations and 9 identity equation). The method of estimation model uses Two Stage Least Squares (2SLS). The simulation results show that the policies of increasing expenses on education, health, and infrastructure with the same value result in the increased employment of workforce in all sectors and reduced poverty. Among these policies, the increased health expenses have the most significant influence on the increase of workforce employment in services sector and reduce poverty. While the policy of increasing expenses on infrastructure has the greatest effect on the increase of workforce employment in industrial and agricultural sectors.

The objectives of the research are: (1) to analyze the influence of increasing education (years of schooling) on labor productivity in agriculture, industry and service of districts and municipalities in Central Java, (2) to analyze the impact of increasing education expenditure policy on economic performance and people welfare. The result of the research shows that the increasing of education in agriculture sector is effective strategy to increase labor productivity in agriculture sector. In the long run, the increasing of education is effective to improve labor productivity in all sectors. The increasing of education expenditure policy could improve local economic performance and people welfare, which is indicated by increasing of human capital accumulation, sectoral labor productivity, sectoral labor demand, gross regional domestic product, government revenue, government expenditure, household expenditure, investment, household expenditure per capita, decreasing of unemployment, inequity and poverty.

The increase in the amount of waste is influenced by the consumption pattern of the people who always want everything practical and fast. On the other hand, the increase in the amount of waste has not been followed by changes in public awareness in its management. Heaps of waste that accumulate in the landfill and have not been managed properly will cause greenhouse gas emissions, one of which is methane (CH4). This gas is produced from solid waste and is more dangerous than CO2. Waste bank management is one of the logical and realistic solutions to be carried out in Indonesia, especially in urban areas such as Meruya Selatan Village, West Jakarta. Waste handling activities from upstream to downstream are mandated by Presidential Regulation number 97 of 2017 concerning National Policies and Strategies in Reducing and Handling Waste. Through good waste management, it is hoped that there will be a reduction in the amount of waste and greenhouse gas emissions that are targeted to be achieved by each City/Regency by 30% and waste management in a city system by 70% by 2025

Pengembangan produk bagi suatu usaha bukan merupakan pilihan, tetapi menjadi keharusan agar usahadapat terus hidup dan berkembang. Secara umum masalah yang dihadapi oleh UMKM(Usaha Mikro Kecildan Menengah), khususnya di Jakarta dan Lampung adalah: 1) kurangnya pengetahuan dan pemahamantentang pentingnya pengembangan produk, 2) kurangnya pengetahuan dan pemahaman tentang pentingnyakreatifitas dan pemanfaatan tehnologi dalam pengembangan produk, dan 3) kurangnya pengetahuan danpemahaman tentang pentingnya aspek pemasaran dalam pengembangan produk. Dalam kegiatanpengabdian masyarakat ini, Universitas Mercu Buana Jakarta bekerjasama dengan Universitas Lampung,Bandar Lampung melakukan kegiatan untuk mengatasi masalah di atas dengan: (1) memberikan ceramahsecara daring tentang pentingnya pengembangan produk, kreatifitas dan pemanfaatan tehnologi dalampengembangan produk, pemasaran dalam pengembangan produk, 2) memberikan pendampingan padasalah satu UMKM terpilih. Kegiatan ini diikuti oleh 32 UMKM di Jakarta dan Lampung. Ceramahdilakukan oleh 9 narasumber dari Universitas Mercu Buana dan Universitas Lampung. Pendampinganusaha dilakukan pada 1 UMKM yang bergerak dalam bidang kuliner. Berdasarkan hasil diskusi selamaceramah daring dan pendampingan UMKM dapat disimpulkan bahwa: 1) kesuksesan usaha/bisnisbergantung pada kemampuan untuk mengidentifikasi kebutuhan pelanggan, kemudian secara cepatmenciptakan produk yang dapat memenuhi kebutuhan tersebut dengan biaya yang efisien, 2) usahapengembangan produk dapat dikatakan sukses, jika produk dapat diproduksi dan dijual serta menghasilkanlaba, untuk itu perlu didukung oleh strategi pemasaran yang jitu dan branding yang baik, dan 3) teknologipenting dalam bisnis karena dapat mempengaruhi sistem kerja perusahaan serta mempermudah danmempercepat pekerjaan.
