Abstract

The development of vapor compression refrigeration systems currently depends on the issue of environmental problems related to ozone layer depletion (ODP) and global warming potential (GWP). In addition to environmental issues, low energy use is also in the spotlight of researchers. To solve the problem of refrigeration development, natural refrigeration, especially hydrocarbons, is the focus of attention. Hydrocarbons are refrigerants that have excellent properties to be natural refrigerants. This study aims to compare the performance of refrigerant R-134a with R-290. The research used a standard vapor compression refrigeration system with a TEV-type expansion valve. The system performance is seen through compression, refrigeration effect, and COP with variations in compressor rotational speed of 1000 rpm, 1500 rpm, and 2000 rpm. The results showed that the compression work, refrigeration effect, and coefficient of performance (COP) of R-290 had a more excellent value. R-290 produces the highest compression work at a 2000 rpm compressor speed of 33.34 kJ/kg for the refrigeration effect at 1000 rpm of 353.33 kJ/kg and COP at 1500 rpm 12.32.

Area jangkauan, skup pengguna teknologi maupun minat pengguna teknologi informasi dari waktu ke waktu terus mengalami peningkatan. Disisi lain perkembangan industri 4 yang terus bergulir diberbagai bidang. Teknologi informasi sangat berperan dalam kemajuan industri 4 dimasa mendatang. Bengkel Unimma Autocare sebagai unit usaha pengembangan kampus sedang mengembangkan kapabilitasnya. Melihat kondisi ini, Bengkel Unimma Autocare sangat perlu menggunakan teknologi informasi sebagai media pengembangan kapabilitas bisnisnya. Metode yang ditempuh dengan membangun website yang dipergunakan untuk pengelolaan manajerial bengkel, media promosi maupun laporan kepada pengguna bengkel. Pembuatan account di media sosial yang digunakan sebagai promosi kepada pengguna bengkel terus digalakkan. Hasil yang diperoleh dari sistem teknologi informasi yang telah dikembangkan diperolehnya sistem teknologi informasi yang terintegrasi dengan unit usaha bengkel. Kemudahan pengelolaan manajerial bengkel dan perluasan promosi bengkel kampus.

Abstract

Gula semut merupakan salah satu produk unggulan daerah Kabupaten Magelang. Kecamatan candimulyo merupakan daerah penghasil gula semut yang cukup banyak. Nira pohon kelapa merupakan bahan baku dalam pembuatan gula semut. Produk ini memiliki kelebihan jika dibanding dengan gula cetak pada umumnya. Produk dapat disimpan dalam jangka waktu satu sampai dua tahun tanpa mengalami perubahan warna dan rasa. Tempat penyimpanan produk memerlukan tempat yang rapat dan kedap udara. Aroma khas karamel palma gula semut sangat sesuai untuk menambah citarasa pada makanan dan minuman. Namun demikian, gula semut yang menjadi komoditi ekspor ini masih kurang dikenal oleh masyarakat magelang dan sekitarnya. Metode yang ditempuh dalam menyelesaikan permasalahan yang dihadapi mitra dengan membantu pengusaha gula semut untuk dapat memasarkan produknya secara sederhana dan tepat sasaran. Kegiatan pemasaran yang dilakukan bertujuan untuk memperluas pemasaran serta mengenalkan gula semut ke masyarakat magelang dan sekitarnya. Kegiatan dilakukan dengan memasarkan gula semut di beberapa pusat oleh-oleh dan toko-toko terdekat. Pemasaran juga dilakukan melalui car free day di kota magelang. Harapan dari kegiatan ini dapat membantu pengusaha gula semut untuk dapat memasarkan produknya dalam jangkauan lebih luas.

Abstract

The emergence of Corona Virus Disease 19 (Covid-19) required a new method to control its spread. During this time, controlling COVID-19 was carried out by implementation of a sterilization chamber using a liquid-based disinfectant. However, the use of liquid-based disinfectants has been evaluated to be less effective because it allows disrupting the respiratory tract. Therefore, this work presents a negative pressure sterilization chamber using Ozone and UV-C lamp. Ozone has been recommended by the Indonesian Institute of Sciences (LIPI) as a substitute for liquid-based disinfectants. In addition, to maximize performance, the chambers are added with UV-C lamps. The negative pressure sterilization chamber with Ozone and ultraviolet lamps was successfully created with the main parts of the cubicle chamber, an Ozone generator, at least one ultraviolet lamp, exhaust fan, switch, and a timer. The negative pressure sterilization chamber with Ozone and ultraviolet lamps according to this work, where the Ozone supply from the Ozone generator is made automatically to the door opening and closing. The duration of the Ozone supply was regulated by a timer. Then, the ultraviolet lamp can be activated together with Ozone or independently. With the implementation of this sterilization chamber, the spread of the Covid-19 virus is expected to be suppressed in a safer way than using liquid-based disinfectants.
