Penerangan Jalan Raya Umum Tenaga Surya / solar cell (PJUTS) adalah alternatif yang digunakan sebagai sumber energi listrik. Cahaya matahari adalah sumber energi yang sangat penting dimana panel surya menerima cahaya matahari dengan kemudian diubah menjadi energi listrik melalui proses photovoltaic. Lampu penerangan di kampung / di area jalan Tubanan Baru Surabaya masih terdapat ruas jalan yang masih kurang pencahayaan / penerangan terutama saat malam hari, oleh karena itu diperlukan rancangan PJUTS. Metode digunakan dengan cara kuantitatif dari sumber yang diperoleh. Penelitian dilakukan untuk mengetahui sudut kemiringan stang ornamen, menentukan jenis tiang, perhitungan daya lampu berbasis LED, intensitas cahaya sebesar 353,3 cd, efisien cahaya K=1,401 dan efikasi cahaya 104,65 lm/watt.

Penelitian ini menganalisis praktik akuntansi keberlanjutan pada Arif Barbershop, sebuah usaha mikro, kecil, dan menengah (UMKM) di Jombang, Jawa Timur, Indonesia. Dengan menggunakan pendekatan studi kasus kualitatif, penelitian ini mengeksplorasi bagaimana barbershop menerapkan prinsip Environmental, Social, dan Governance (ESG) dalam operasional sehari-hari. Data dikumpulkan melalui wawancara mendalam dengan pemilik usaha dan dianalisis menggunakan analisis tematik. Temuan menunjukkan bahwa Arif Barbershop telah menerapkan praktik lingkungan dasar seperti pengelolaan limbah rambut melalui kantong plastik ke tempat pembuangan sampah, serta efisiensi energi dengan mematikan peralatan listrik setelah jam operasional. Dari aspek sosial, barbershop menjaga kepuasan pelanggan melalui konsistensi kualitas layanan dan sistem bagi hasil (60:40) kepada karyawan. Praktik tata kelola, meskipun bersifat informal, mencakup pencatatan keuangan sederhana menggunakan buku biasa. Namun demikian, barbershop belum memiliki izin usaha formal dan belum menerapkan kerangka akuntansi keberlanjutan yang terstandar. Penelitian ini menyoroti bahwa UMKM dapat mempraktikkan akuntansi keberlanjutan secara intuitif, dan menyarankan perlunya program pelatihan serta alat pelaporan yang disederhanakan.

Electricity dependence is increasing as people have easier access to electronic devices. However, this ease of access is not always accompanied by adequate energy literacy. In its Community Service program, Universitas 17 Agustus 1945 Jakarta helped to educate the residents in RW06 Kalibaru, Jakarta, about the safe and efficient use of electricity. This community service program was conducted through participatory seminar with a qualitative approach for residents. The activity used informal visual presentations and discussions in an informal atmosphere. The outreach program demonstrated residents' high enthusiasm for the efficiency of electrical equipment usage such as air conditioners, refrigerators, and water pumps. Through the discussion session, residents realized that using air conditioners with too low a power consumption actually leads to higher energy consumption because the compressor runs continuously. Participants understood that investing in automation concepts, such as using water reservoirs, provides significant long-term electricity cost savings. This outreach successfully shifted residents' paradigm from just simply seeking low prices to selecting devices with optimal capacity according to their needs. This education program demonstrates the effectiveness of energy literacy in improving electricity consumption habits at the household level. Therefore, simple technical understanding can boost family economic financial advantages through sustainable effective energy consumptions.

The commercial sector, especially the hospitality industry, is one of the largest consumers of electrical energy, with energy costs often ranking as the second highest operational expense. This study aims to conduct a specific Electrical Energy Audit in the Office Engineering unit of Aston Denpasar Hotel & Convention Center to optimize electricity usage and improve energy efficiency. The research applies a detailed audit approach with a focus on lighting systems and air conditioning (AC), which are major contributors to energy consumption. The initial stage involves calculating the actual Energy Consumption Intensity (IKE) in kWh/m²/month and comparing the results with ASEAN and SNI standards to determine the efficiency classification of the building. Data collection is carried out through direct field measurements as primary data, using instruments such as a Clamp Meter and Lux Meter. The expected outcome of this study is the identification of detailed Energy Saving Opportunities (ESO), along with the estimation of potential monthly energy cost savings and the calculation of the investment Payback Period.
