Konsumsi energi diyakini akan berdampak pada pertumbuhan ekonomi Indonesia. Sebagian besar energi yang dikonsumsi di Indonesia berasal dari energi fosil dan sejumlah kecil energi terbarukan. Studi ini akan menguji hubungan antara konsumsi energi terhadap pertumbuhan ekonomi di Indonesia, dengan variabel kapital dan tenaga kerja sebagai variabel lain yang dapat mempengaruhi produk domestik bruto (PDB). Untuk melihat hubungan antar variabel dilakukan Uji Kausalitas Granger. Hasil pengujian menunjukkan bahwa terdapat hubungan dua arah antara konsumsi minyak, gas alam dan energi tak terbarukan dengan pertumbuhan ekonomi atau memenuhi hipotesis umpan balik. Terdapat hubungan satu arah antara konsumsi batubara dan pertumbuhan ekonomi atau memenuhi asumsi pertumbuhan. Selain itu, dilakukan pemodelan dengan menggunakan metode autoregressive distributed lag (ARDL), sehingga dapat diketahui hubungan jangka panjang dan jangka pendeknya. Berdasarkan hasil penelitian terdapat hubungan jangka panjang.
Pasokan energi menjadi salah satu landasan ketahan suatu negara untuk dapat melangsungkan kedaulatan negara. Kebutuhan energi di Indonesia masih didominasi oleh sumber energi yang berasal dari bahan dasar fosil, baik itu minyak bumi, gas bumi, maupun batu bara. Konsumsi energi di Indonesia semakin meningkat seiring dengan bertambahnya waktu, peningkatan kebutuhan terhadap pasokan energi baik pada sektor usaha maupun sektor rumah tangga sekalipun. Perbandingan konsumsi terhadap pasokan energi yang di dominasi oleh sumber energi fosil masih mengalamai defisit, dimana konsumsi energi masih lebih besar dibandingkan dengan pasokan energi dalam negeri sehingga perlu dilakukan impor sumber daya fosil dari negara lain. Mengantisipasi hal tersebut perlu dilakukan upaya dalam menghadapi devisit yang ada, dengan mendorong masyarakat untuk sadar dan mandiri dalam menciptakan sumber energi dengan menggunakan sumber daya alam yang ada di sekitar masyarakat dan mengubahnya menjadi energi baru terbarukan. Pelatihan perakitan panel surya sebagai energi baru dan terbarukan yang dilakukan pada daerah RT 016 RW 003 Lagoan menadapatkan respon positif dari warga. Antusiasme warga dalam mengetahui kebutuhan energi dan kemendarian energi sangatlah besar dan bagus hingga kebanyakan warga meminta untuk dapat melanjutkan pelatihan lainnya untuk membuat energi baru terbarukan.
<p>In this pandemic period, people are required to be more creative and able to see the slightest opportunity. Although these opportunities come from waste that is usually discarded or not reused, such as waste cooking oil. Waste cooking oil is usually thrown into the sewer. Therefore, proper handling is needed so that waste cooking oil is beneficial and does not cause harm from aspects of human health and the environment. Various efforts have been made, one of them by making candles from used cooking oil.</p>The location of this community service activity is in RW 07, Duri Pulo Village, Central Jakarta. The main purpose of community service activity at this location is to provide training and knowledge to housewives of RW 07 Kelurahan Duri Pulo, Central Jakarta regarding the importance of processing the waste cooking oil waste in order to provide added value that can improve their life economy. Candles are an object that has a fairly important role in human daily life, especially when there is no electricity. Socialization and training are the methods chosen in this community service activity. This is because direct learning is easier to remember than just counseling. This activity went smoothly and received good enthusiasm from the housewives of RW 07 Duri Pulo Village, Central Jakarta. These housewives asked our team to regularly held this community service activity and even suggested to conduct further research on the purification of the waste cooking oil so that it is safe to reuse like a new cooking oil
Shovel production can be affected by several factors, such as shovel working time and working conditions. The shovel production for the inter-burden removal target did not achieve at mining operations in Melak, East Kalimantan. This study’s main objective is to find the causes of the inadequate production and the efforts to improve. In this case study, the high delay due to the waiting for truck maneuvering caused the lack of shovel production. Some corrections were needed on the width of the loading point, and the loading method required to be replaced with double-side loading. Changes in the width of the loading point and loading method have an impact on increasing shovel productivity. In addition, a digger working time simulation is performed based on secondary data. Calculation of total production achievement is based on the simulation of time categories with working, standby, and repair time variables.
