The global Electricity Sector and its customers are faced with a number of challenges that are unparalleled since the advent of widespread electrification. Challenges including climate change, escalating energy prices, energy security and energy efficiency are converging to drive fundamental change in the way energy is produced, delivered and utilized. The electricity system of the future must produce and distribute electricity that is reliable, affordable and clean. To accomplish these goals, both the electricity grid and the existing regulatory system must be smarter. This paper explores smart grid technologies, distributed generation systems, R & D efforts across Europe and the United States, and technical, economical and regulatory barriers facing modern utilities

In the 21st century Smart Grid and Renewable Energy technologies are an important issue with regards to global climate change problem and energy security. The evolution of current conventional or centralized generation in form of distributed generation and Smart Power Grid (SPG) has great opportunity and potentially can eradicate several issues associated with energy efficiency, energy security and the drawback of aging power system infrastructures. In order to meet the rising electrical power demand and increasing service quality as well as reducing pollution, the existing power grid infrastructure should be developed into Smart Grid (SG) that is flexible for interconnectivity with the distributed generation. However, integrating distributed generation to power system causes several technical issues especially system stability. To make the power grid become “smarter”, particularly in terms of stability, Flexible AC Transmission System (FACTS) device especially Static VAR Compensator (SVC) is used. This paper explores Smart Grid technologies and distributed generation systems. Furthermore, it discusses the impact of distributed generation on Smart Grid, particularly its system stability after installing distributed generation in the Smart Grid. This was done by examining the system stability during interconnection and faults on the system and validated with Dig-SILENT Power Factory Software V 13.2

Stemming Javanese affix words using Nazief & Adriani modifications still has problems that cannot be solved such as overstemming, understemming, and unchange. Then there needs to be improvements to improve the performance of Nazief & Adriani modifications. This study aims to improve the performance of Nazief & Adriani modifications using the Enahnced Confix Stripping (ECS) modification method. The results of this study indicate that Enhanced Confix Stripping can improve performance that previously had an accuracy of only 78.2% to 97.9% with an error rate of 2.1%. And fixing errors that originally numbered 98 to 9 errors. But Enhanced Confix Stripping still has problems with the words "ngetan, kumanggah, kumarut, kumasis, kumareg, kumadul, kumaras, katawakake, and pangenan". The next research is expected to be able to solve this problem.

Untuk memenuhi kebutuhan energi listrik yang terus meningkat serta tuntutan energi yang ramah lingkungan, efisien dan berkelanjutan, maka pemanfaatan energi terbarukan harus terus ditingkatkan. Metode yang digunakan adalah dengan membangun pembangkit listrik tenaga angin turbin sumbu horizontal. Teknologi ini mempunyai kelebihan bisa menangkap angin dengan kuat, karena posisinya yang tinggi, efisiensi rotor yang lebih tinggi di banding tipe vertikal, bisa diarahkan  ke arah angin, dan mempunyai mekanisme perlindungan terhadap angin yang merusak.Keunggulan teknologi ini sangat cocok dengan topografi negara Indonesia yang memiliki kecepatan angin relatif rendah.Pembangkit listrik tenaga anginturbin sumbu horizontal mempunyai rasio daya yang rendah. Rasio daya keluaran   pembangkit   listrik   tenaga   angin   dengan   turbin   tipe horizontal hanya sekitar 30% dari daya angin yang melewati turbin. Pada penelitian ini, untuk meningkatkan daya keluaran pembangkit listrik tenaga angin maka digunakan metode Maximum Power Point Tracker.   Dari hasil percobaan dengan berbagai kecepatan angin di dapati bahwa rata-rata daya tanpa MPPT hanya sekitar 44,33% saja sedangkan yang dengan MPPT rasio daya rata-rata mengalami kenaikan yaitu sebesar 49,51%.
