Abstract

Abstrak: Kegiatan ini dilakukan pasca Pandemi COVID-19 di Indonesia. Dampak Pandemi COVID-19 di Indonesia secara signifikan sangat mengganggu ekonomi di Indonesia, pusat belanja banyak ditinggalkan konsumen dalam hal ini penyewa toko. Saat ini, gedung mulai beroperasi secara normal. Tentunya terjadi perubahan profile energi sebelum dan pasca terjadi pandemi. Profile energi diperlukan untuk melihat indeks konsumsi energi (IKE). Kegiatan pendampingan pengukuran beban listrik ini bertujuan untuk melihat profile konsumsi energi dan analisisnya menghasilkan nilai IKE. Hasil pendampingan berjalan dengan lancar atas 15 orang teknisi secara bergilir. Metode pendampingan dalam kegiatan ini berupa arahan teknis dan klasifikasi pengukuran beban listrik bangunan berdasarkan kelompok profile konsumsi energi. Hasil pendampingan berupa profile konsumsi energi. Hasilnya terjadi anomali dimana konsumsi energi untuk sistem AC yang digunakan hanya 48 %, sedangkan nilai rata-rata di pusat perbelanjaan di Indonesia adalah 62,9 %. Besarnya listrik yang dijual kembali kepada tenant mencapai 37 %, selebihnya digunakan untuk mendukung fasilitas gedung lainnya. Kegiatan ini juga menghasilkan analisis IKE sebesar 17,46 kWh/bulan/m2 atau setara dengan 209,47 kWh/m2/tahun untuk nilai GFA (Gross Floor Area).Abstract: This activity was carried out after the COVID-19 Pandemic in Indonesia. The impact of the COVID-19 Pandemic in Indonesia has significantly disrupted the economy in Indonesia; many shopping centers have been abandoned by consumers, in this case, shop tenants. Currently, the building is starting to operate normally. Of course, there was a change in the energy profile before and after the pandemic. The energy profile is needed to see the energy consumption index (IKE). This assistance activity aims to see the energy consumption profile and its analysis to produce an IKE value. The results of the assistance went smoothly for 15 engineer. The assistance method in this activity is in the form of technical directives and classification of building electrical load measurements based on load group profiles. The assistance results in the form of an energy consumption profile. The result is an anomaly where the energy consumption for the AC system used is only 48 %, while the average value in shopping centers in Indonesia is 62.9 %. The amount of electricity resold to tenants reaches 37 %, and the rest is used to support other building facilities. This activity also resulted in an IKE analysis of 17.46 kWh/month/m2, or the equivalent of 209.47 kWh/m2/year, for the GFA (Gross Floor Area) value.

Abstract

The current development of the cellular communication system has ushered in the 5G telecommunications era. The government has provided a 2.3 GHz frequency spectrum for 5G implementation in Indonesia. The frequency value used in the implementation of 5G technology in Indonesia which has just started can be said to have a high impact with a high attenuation value, so an antenna with the right dimensions and parameters is needed to be used in the application of 5G technology. In this study, a microstrip antenna was designed and manufactured with a 2x8 patch circular array shape working at a frequency of 2,350 MHz for application to 5G technology using the microstrip line feed feeder method. The design and manufacture of the antenna design utilize the Ansys HFSS application and uses the FR-4 Epoxy substrate with a dielectric constant value of 4.4, a substrate thickness of 1.6 mm, and a patch made of copper. The results of the design based on the simulation results obtained the working frequency value at 2,350 MHz with a return loss value of -21.9711 dB and a wide bandwidth of 109 MHz. The VSWR value obtained is 1.0849 with a gain value of 10.06 dB and a directional radiation pattern. Based on the results of the analysis, the microstrip antenna design test has good parameter values from previous studies at the same working frequency and the microstrip antenna is suitable for use to support the development of 5G technology.

Abstract

Abstrak: Ancaman nyata dampak ekplorasi air bersih di Indonesia adalah menurunnya permukaan tanah utamanya di sekitar Pantai. Kota Jakarta, Semarang dan kota-kota besar di pesisir utara pulau Jawa sudah merasakan dampaknya. Untuk mengatasi permasalahan ini perlu dilakukan upaya konservasi lingkungan melalui pengendalian penggunaan air tanah. Gedung Inalum memiliki fasilitas pengolahan air limbah tetapi belum difungsikan. Kegiatan ini bertujuan untuk pendampingan para teknisi Gedung Inalum yang jumlahnya 14 orang dalam pemanfaatan air limbah sebagai air non-potabel untuk menyiram tanaman dan toilet Dengan adanya pendampingan, para teknisi yang ada mampu untuk melaksanakan kegiatan secara mandiri dan mampu meningkatkan hard skill mereka. Metode pendampingan yang dipakai adalah dengan pengawasan proses pengolahan air limbah dan perawatan peralatan pengolahan air limbah mulai dari sewage treatment plant, proses pemfilteran air, pompa transfer dan utilitas pemipaan.Kegiatan ini berhasil menurunkan konsumsi air bersih yang semula 728 m3 per bulan menjadi 270 m3 per bulan atau turun sebesar 62,91%. Sedangkan air yang dibuang ke saluran kota menurun yang 565 m3 turun menjadi 107 m3 atau turun 81,06%.Abstract: The real threat from water exploration in Indonesia is land subsidence, especially around the coast. Jakarta, Semarang and other major cities on the north coast of Java have already felt the impact. To overcome this problem, it is necessary to conserve the environment through controlling the use of groundwater. The Inalum building has a wastewater treatment facility but it has not been utilised. This activity aims to assist 14 Inalum Building technicians in the utilisation of wastewater as non-potable water for watering plants and toilets. With the assistance, the existing technicians are able to carry out activities independently and are able to improve their hard skills. The mentoring method used is to supervise the wastewater treatment process and maintenance of wastewater treatment equipment starting from the sewage treatment plant, water filtering process, transfer pump and piping utilities. This activity succeeded in reducing clean water consumption from 728 m3 per month to 270 m3 per month or a decrease of 62.91%. While water discharged into city drains decreased from 565 m3 down to 107 m3 or down 81.06%.

Solar panels utilize photovoltaics and are a renewable source of electricity generation. The efficiency of solar panels depends on the surface condition of the panels. Objects that block sunlight can interfere with the efficiency of the electricity produced. One of the buildings with a solar power plant is the Inalum building. The problem is that technicians need to understand the maintenance of solar power plants. For this reason, training is proposed in this building to provide additional knowledge. Eleven technicians and two supervisors attended the training. The training process received an assessment of 4.23 on a scale of 5. Meanwhile, this training increased the training participants' abilities by 60.77% to 95.38% or an increase of 34.16%. With this training, the solar power plant in the Inalum building will have good efficiency through regular maintenance.
