Judul: Economic Behavior and Community’s Efforts in Saving Electrical Energy in Bogor Regency (Case Study: Household Electric Energy Consumers at Pondok Kencana Permai Housing)
Abstrak: Kabupaten Bogor memiliki jumlah pelanggan rumah tangga tersambung energi listrik yang sangat banyak. Adanya perubahan gaya hidup di masyarakat dan perilaku penggunaan energi yang masih tidak efisien menyebabkan tingginya permintaan energi listrik. Sementara, dari sisi penawaran kapasitas pembangkit listrik dan kemampuan membeli energi masih terbatas sehingga menyebabkan tingginya frekuensi pemadaman energi listrik. Dengan adanya Sustainable Development Goals (SDGs) tujuan ketujuh, Peraturan Menteri Energi dan Sumber Daya Mineral Nomor 13 Tahun 2012, dan upaya Gerakan Hemat Energi “Potong 10%”, upaya penghematan energi listrik menjadi hal yang penting dilakukan. Penelitian ini bertujuan untuk (1) Menganalisis pola konsumsi dan biaya konsumsi energi listrik di Perumahan Pondok Kencana Permai pada sebelum dan saat pandemi Covid-19, (2) Menganalisis persepsi dan upaya masyarakat dalam penghematan energi listrik di Perumahan Pondok Kencana Permai, (3) Menganalisis korelasi antara pola konsumsi energi listrik dengan karakteristik sosial ekonomi masyarakat di Perumahan Pondok Kencana Permai. Metode analisis yang digunakan adalah analisis deskriptif, skala likert, dan analisis korelasi Pearson. Hasil analisis menunjukkan bahwa pola konsumsi energi listrik selama pandemi Covid-19 meningkat dibandingkan sebelumnya dan menyebabkan sebanyak 57% responden mengalami peningkatan terhadap biaya tagihan energi listrik. Sebagian besar masyarakat setuju dan sudah melakukan upaya-upaya penghematan energi listrik. Hasil penelitian juga menunjukkan bahwa aktivitas memakai laptop, daya listrik, pendapatan, dan lama penggunaan AC berkorelasi signifikan dan positif terhadap biaya tagihan listrik, Bogor Regency has a very large number of household customers connected to electrical energy. Changes in lifestyle in society and inefficient use of energy have resulted in high demand for electrical energy. Meanwhile, from the power supply’s side generation capacity and the ability to buy energy are still limited, resulting in high frequency of power blackouts. The existence of the seventh goal of Sustainable Development Goals (SDGs), Regulation of the Minister of Energy and Mineral Resources Number 13 of 2012, and efforts to Save Energy Movement "Cut 10%", efforts to save electrical energy are important things to do. This study aims to (1) analyze consumption patterns and costs of electricity consumption in Pondok Kencana Permai Housing before and during the Covid-19 pandemic, (2) Analyze public perceptions and efforts in saving electrical energy at Pondok Kencana Permai Housing, (3) Analyzing the correlation between the patterns of electricity consumption and the socio-economic characteristics of the community in Pondok Kencana Permai Housing. The analytical method used is descriptive analysis, Likert scale, and Pearson correlation analysis. The results of the analysis show that the pattern of electrical energy consumption during the Covid-19 pandemic has increased compared to the previous one and caused 57% of respondents to experience an increase in the cost of electric energy bills. Most of the people agree and have made efforts to save electrical energy. Other than that, activities using a laptop, electric power, income, and length of time using AC have a significant and positive correlation to the cost of electricity bills.

Judul: Analisis pembentukan perilaku hemat listrik dengan pendekatan norm activation model (kasus pelanggan listrik rumahtangga di Kota Bogor)
Abstrak: The use of electrical energy is an important factor to support some activities in daily life, industries, households, educational activities, transportations, lightings, and communications. Indonesian people are still doing inefficient utilization of energies, including electrical energy. Saving the energy is an important part of efficiency. The study was aimed to analyze: 1) characteristics of household at differnt electricity power class; 2) the correlations between awareness, responsibility, personal norms, behavior intention and electrical energy saving behavior in household; 3) factors that influence norm activation model in household; 4) some factors which influence the electrical energy saving behavior, electrical cost and the use of electrical tools in household. This study design was cross sectional study. This study was conducted in Taman Cimanggu region which is a location where KDK (Kedung Waringin Komplek) electrical substation exists, with the subject was household in Taman Cimanggu. The results found that respondent get the information about electrical energy saving from many medias and reference groups. The awareness, resposibility, personal norms, and behavior intention variable were not correlated with electrical energy saving behavior. Respondents were still to intend to save the energy, however they were not doing some actions. Althought respondents want to do some actions to save the electrical energy, but it is still on average level. The multiple linear regression result showed that some factors which have significant effect on electrical energy saving behavior, that were: electrical power class, knowledge, number of information and responsibility.

Judul: Penyusunan Overlap Graph menggunakan Suffix Tree pada DNA Sequence
Abstrak: The DNA sequence assembly is very important in genome analysis. This step aims to reconstruct contigous DNA fragment (contigs) from short fragment by concatenating fragments based on the overlap region among them. This method employs overlap graph for solving the problems. In this graph, nodes represent fragments and edges represent overlap. This research developed a software for constructing overlap graph using suffix tree. The evaluation was conducted by measuring the number of nodes, number of edges, and the execution time in many values of minimum overlap. The minimum overlap is defined as the minimum length of substring which is considered as the overlap region between two fragments. The evaluation results showed that the number of nodes, the number of edges, and the execution time were increased with the decreasing of the minimum overlap value.
