Bioetanol memiliki banyak fungsi dan kegunaan, diantaranya sebagai pelarut. Bioetanol belakangan ini dikenal sebagai salah satu bahan bakar alternatif yangcukup potensial, selain dapat dibuat dengan mudah dan dengan biaya murah,bioetanol juga dapat dibuat dari berbagai bahan baku yang ada di alam. Pada penelitian ini dibuat bioetanol dari kulit pepaya, tujuannya adalah untuk mengkaji pengaruh jumlah ragi dan waktu fermentasi terhadap jumlah bioetanol yang diperoleh. Hasil penelitian didapatkan bahwa volume bioetanol tertinggi 31,17 ml didapatkan pada perlakuan waktu fermentasi selama 4 hari dan penambahan ragi Saccaromyces cereviceae sebanyak 15 gram, densitas bioetanol tertinggi diperoleh pada jumlah ragi 15 gram dengan waktu fermentasi 4 hari yaitu 0,883 gr/ml, pH media tertinggi selama fermentasi yaitu 5 yang terdapat pada jumlah ragi 20 gram dengan waktu fermentasi 3, 4, dan 5 hari. Rendemen bioetanol yang paling tinggi diperoleh pada jumlah ragi 15 gram dengan waktu fermentasi 4 hari yaitu sebesar 6,23%.

Measles is a contagious infections disease that attacks children caused by a virus. Transmission of measles from people through coughing and sneezing. Measles causes disability and death, so further threatment is needed. Measles immunization program that can inhibit the development of measles is one of the efforts in eradicating the disease. In this study the data used were sourced from the Central Statistics Agency National in 2013-2017. This study uses datamining techniques in data processing with K-Medoids algorithm. The K-Medoids method is a clustering method that functions to break datasets into groups. The advantages of this method are the ability to overcome the weaknesses of the K-Means method which is sensitive to outliers. Another advantage of this algorithm is that the results of the clustering process do not depend on the entry sequence of the dataset. The k-medoids clustering method can be applied to the data on the percentage of measles immunization can be identified based on province, so that the grouping of provinces based on these data. From the data grouping three clusters are obtained: low cluster (2 provinces), medium cluster (30 provinces) and high cluster (2 provinces) with the percentage of measles immunization in each of these provinces from data grouping in percentage. It is expected this research can provide information to the govermant about the data on grouping measles immunization for toddlers in Indonesia which has an impact on the distribution of immunization against measles toddlers in Indonesia.

Abundant potential of renewable energy (RE) in Indonesia is predicted to replace conventional energy which continues to experience depletion year by year. However, until now, the use of RE has only reached 2% of the existing potential of 441.7 GW. The main overview of this work is to investigate the availability of RE that can be utilized for electricity generation in Indonesia. National energy demand and targets in the long run during the 2017–2050 period are also discussed. Besides, government policies in supporting RE development are considered in this work. The results show that the potential of RE in Indonesia can be utilized and might replace conventional energy for decades. The use of RE for electricity generation can be achieved by employing a government policy that supports the investor as the executor of RE development. The selling price of electricity generated from RE is cheaper than electricity generated from fossils; this makes economy is more affordable for people. Finally, the target set by the government for utilizing RE as the main energy in Indonesia can be done by implementing several policies for the RE development. Thus, greenhouse gas emissions and the use of petroleum fuels can be reduced.

Mining age and technology have led to the emergence of an innovation that can help facilitate human activities, especially for parents in controlling and looking after babies. By implementing a sound monitoring system in the baby room based on the Arduino Atmega 328 microcontroller which functions to detect noise. Data from the voice sensor is processed by Arduino via a pin. So Arduino will give instructions to Buzzer to send alarm notifications

Objective – This study aims to analyze the performance of village governments in managing financial resources of the budget year 2016 in Lut Tawar District, Central Aceh Regency, according to the Indonesian Minister of Home Affairs Regulation (or PERMENDAGRI) No. 113, 2014. Design/methodology – This research is a descriptive research with a qualitative approach is a type of research where the researcher describes or deeply analyzes the result of a research about an object and then adds it with sources which already existed in the research object. The data was gathered through number of interviews and document analysis.  Results – The result of the research shows that the performance of the village government in managing fund allocation in Lut Tawar Sub-district at the planning stage has been running well. The implementation stage has been completed where all the programs and activities are executed in accordance with the plan. The administrative stage has been done well by the treasurers and every month the treasurers have accounted for every acceptance and expenditure to the village headmen. In the reporting stage, the delay in submitting accountability report is caused by some negligence by the party from the village government. At the accountability stage, the accountability reports were reported as well as evaluated with the village government community and transparent to the community for every use of village funds in the form of information posted on the information boards in the office of the village headmen and billboards installed in front of the village headman office.

Salah satu sumber daya alam yang berpotensi untuk zat warna alam adalah tumbuhan jamblang. Bagian tanaman jamblang yang dapat digunakan sebagai zat warna alami adalah bagian kulit batangnya karena mengandung tanin. Tanin merupakan pigmen pada kulit batang jamblang (Syzygium cumini) yang menghasilkan warna coklat yang dapat dijadikan sebagai pewarna tekstil. Penelitian ini bertujuan untuk mencari kondisi operasi yang sesuai dari ekstraksi serbuk kulit batang jamblang terhadap pengaruh suhu dan waktu ekstraksi terhadap kadar zat warna yang dihasilkan serta menganalisa mekanisme penyerapan zat warna pada kain. Penelitian ini dilakukan dengan mengekstrak kulit batang jamblang 100 gram, volume etanol 1000 ml pada suhu 60, 65, 70, 75 dan 800C selama 2, 3, 4, 5 dan 6 jam. Hasil serbuk zat warna diamati Intensitas warna dengan alat colorimeter yang menghasilkan warna terbaik yaitu 5,0 pada suhu 700C dengan waktu ekstraksi 6 jam menghasilkan kadar air sebanyak 0,071%, kadar abu 0,068%.

Illiteracy is the state of being unable to read and to write for communication. A large number of people still experiencing illiteracy in a country is one indicator showing that the country is still not developed. As many as 3.4 million people or around 2.07% of the population in Indonesia are still illiterate. This study aims to create a grouping model using the k-medoids algorithm. The k-medoids method is a clustering method that serves to break down datasets into groups. The data used is sourced from the Central Statistics Agency. Entered data are percentage of illiterate population in 2009-2017. The number of records used is 34 provinces which are divided into 3 clusters namely high cluser, medium cluster and low cluster. From the results of k-medoids calculation, one (1) province was categorited as a high cluster, twelve (12) provinces as a medium cluster and twenty-one (21) provinces as a low cluster. The implementation process using the RapidMiner 5.3 application is used to help find accurate values. It is hoped that this research can be used as one of the bases for decision making for the government in an effort to equalize the level of illiteracy according to the province which has an impact on reducing of illiteracy rates in Indonesia.
