Abstract

Abstrak: Pandemi COVID-19 berdampak pada diberlakukannya Pembatasan Sosial Berskala Besar atau PSBB. Salah satu implementasi dari PSBB adalah dengan dilaksanakannya proses belajar mengajar secara Online atau daring. Sekolah secara daring memang cukup efektif dalam masa pandemi ini. Permasalahan yang timbul adalah dibutuhkan sarana trafik data untuk melaksanakan kegiatan pembelajaran Online. Tujuan kegiatan Pengabdian kepada Masyarakat ini adalah menyediakan layanan Wi-Fi gratis di wilayah Kecamatan Jonggol, Kabupaten Bogor untuk mendukung kegiatan pembelajaran secara Online. Jaringan Wi-Fi ini dibangun dipemukiman padat di salah satu rumah penduduk. Hasilnya Wi-Fi tersebut dimanfaatkan oleh murid-murid pelajar sekolah dasar, sampai perguruan tinggi dengan peserta rata-rata 4 sampai 5 orang dalam satu sesi. Rata-rata pengguna harian 10 orang. Kecepatan data maksimal mendekati 252 Kbps. Pada kondisi 10 pengguna kecepatan rata-rata pada 150 Kbps. Kendala yang didapati adalah terbatasnya area jangkauan sinyal Wi-Fi dan adanya larangan berkumpul di satu titik oleh aparat setempat. Disarankan untuk kegiatan berikutnya untuk dikembangkan dengan berbagi Wi-Fi, sehingga pengguna bisa mengakses dari rumah masing-masing.Abstract: The COVID-19 pandemic has resulted in the enactment of Large-Scale Social Restrictions or PSBB. One of the implementations of PSBB is the implementation of Online or Online teaching and learning processes. Online schooling is indeed quite effective during this pandemic. The problem that arises is that data traffic facilities are needed to carry out Online learning activities. The purpose of this Community Service activity is to provide free Wi-Fi services in the Jonggol District, Bogor Regency to support Online learning activities. This Wi-Fi network was built in a dense settlement in one of the residents' houses. The result is that Wi-Fi is used by students from elementary school to college with an average of 4 to 5 participants in one session. The average daily users are 10 people. The maximum data rate is close to 255 Kbps. In the condition of 10 users, the average speed is 150 Kbps. The obstacles found are the limited coverage area of the Wi-Fi signal and the prohibition of gathering at one point by local officials.

Abstract

This Community Service activity was carried out at the PT Indonesia Asahan Aluminum (Persero) Head Office Building, Batubara Regency, North Sumatra. This building has a green building concept. The green building concept requires workers to come from residents around the building. The building, which the Minister of SOEs inaugurated on January 6, 2021, is managed by local sons. The problem is that Inalum building management workers have no experience using LFE (Light Fire Extinguishers). To overcome these problems, training in the use of APAR is needed. This activity aims to provide training to Inalum building management employees. Participants The exercise was attended by 53 participants from the technicians, security guards, housekeeping, receptionists, gardeners, and gondola officers. Based on gender, the activity was attended by nine women and 44 men. Before the training, the level of understanding of officers about APAR was only 42%, while after the training, it increased to 70.75% or an increase of 28.68%.

Abstract

Energy conservation in Indonesia is the primary choice made by the government of the Republic of Indonesia. It is undeniable that the highest consumption of a building is air conditioning energy, especially in a tropical environment like Indonesia. Air conditioning consumes between 40% and 80% of power in a high-rise building. The problem is how to find out the electricity usage profile and energy consumption index in a building that has been in operation for more than 20 years. This research aims to find the energy profile and calculate the energy consumption of a shopping center building. The method used is an Energy Audit according to SNI 6196. The energy consumption profile is an anomaly where the energy consumption for the air conditioning system is only 48%, while the average value in shopping centers in Indonesia is 62.9%. Meanwhile, the GFA energy consumption index is 23.11 kWh/m2/month or 277.3 kWh/m2/year. According to SNI 03-0196, the result is classified as an energy-intensive building. This value is close to the SNI 03-0196 standard for very energy-intensive building levels, which has values between 23.75 and 37.5 kWh/m2/month. Energy-saving opportunities are calculated by calculating the difference in the ECI value with the target ECI value. To increase the efficiency of energy consumption, this can be done by replacing the chiller unit which still uses a step type compressor. Apart from that, improving air conditioning insulation is very significant to overcome energy consumption problems. Adding green plants around buildings can also increase electrical efficiency.
