Abstract

During operation, the evaporator of split-type air conditioner (A/C) produces condensate water due to lower evaporator temperature, as compared to dew point temperature of the indoor air. So far, the condensate is considered unimportant and therefore being wasted. The split-type A/C is widely used in high-rise buildings, hotels, shopping areas, and even residential. The study aims to investigate the potential feasibility of the condensate to be used as for drinking water. Of course, treatment of the condensate is required before it can be used as a drinking water. The experiments were carried out in two cities, namely Bandung and Cirebon. Bandung represents a city with a cool climate, while Cirebon represents a city with a hot climate. The capacities of the A/C utilized in Bandung and Cirebon are 0.5 HP and 1 HP, respectively. The quantities of the condensate from the A/C were collected for 24 for hours. The quality of the condensate was benchmarked with guidelines/standard from PERMENKES NO 492/MENKES/PER/IV/2010. The benchmarking process involved testing and evaluation of 22 significant parameters related to water quality for drinking purpose. By utilizing waste condensate water, it is predicted that it can be a vital alternative of potable water in the future

Abstract

SMK Manangga Pratama consists of several majors including Motorcycle Business Engineering (TBSM), Automotive Light Vehicle Engineering (TKRO), and Sofware Engineering (RPL). In major Automotive Light Vehicle Engineering (TKRO), some subjects discuss the Air Conditioning system (automotive AC and split room AC). The problem is the lack of equipment for vacuuming, and charging refrigerants for automotive AC units to be used and empowered as a learning resource. The main cause is the lack of affordable equipment for service, unit maintenance. This of course will be a problem when the students have graduated and need direct application to the Automotive AC system and the room. There are about 110 students from the Automotive Light Vehicle Engineering (TKRO) Department in each batch, with such a large number, it would be better if they were given an additional briefing on these skills. This PkM program has been equipped and provided with equipment and service equipment to be used by students as a training unit in improving their skills. The manufacture of tables and assembly of training units for automotive AC service completeness (charging, pumping, and other tools) will be carried out on the Polban Bandung campus. Instructor trainers in this PkM training program are several teaching staff in the Refrigeration and Air Conditioning Engineering Department, while the unit is a complete unit for automotive air conditioning units and rooms, namely (charging, pumping, and other tools). The implementation of community service activities majoring in refrigeration and air conditioning engineering POLBAN as a form of higher education tri dharma has been completed on October 28-29 at SMK Manangga Pratama. The activity consisted of making practicum tools for strengthening school laboratories, accompanied by providing training for the service and maintenance of air conditioning machines (AC).

Abstract

Minuman susu segar termasuk salah satu minuman favorit yang banyak dikonsumsi masyarakat, dan termasuk salah satu jenis minuman yang tidak dapat bertahan lama pada suhu lingkungan, akibat banyak sekali zat yang memicu bakteri untuk tumbuh dan berkembang biak dengan mudah di dalam susu. Pada penelitian ini dibahas tentang sistem pembunuh bakteri pada susu dengan menggunakan kombinasi sistem refrigerasi, heater dan listrik tegangan tinggi.Pada tahap awal susu segar dengan jumlah 4 liter dipanaskan oleh heater hingga mencapai suhu pasteurisasi (60oC – 70oC ), kemudian diberi tegangan tinggi listrik ( 25 kv) dan terakhir suhunya dipertahankan pada 4oC dengan sistem refrigerasi. Setelah proses-proses tersebut didapatkan hasil bahwa untuk mencapai suhu pasteurisasi dibutuhkan 844.800 Joule dalam waktu 40 menit. Tegangan listrik tinggi yang dikeluarkan flyback selama 5 menit mampu membunuh sebagian bakteri di dalam susu dan untuk mencapai suhu 4oC pada sistem refrigerasi butuh waktu 120 menit. Dengan proses-proses tersebut sistem berhasil menurunkan kuantitas bakteri di dalam susu.

Abstract

Air Handling Unit (AHU) merupakan komponen utama sistem tata udara yang berfungsi mengondisikan dan mensirkulasikan udara untuk menjaga kualitas lingkungan ruang operasi. Penelitian ini bertujuan merancang AHU berkapasitas 10 PK dengan cooling capacity 100.000 Btu/h menggunakan sistem Direct Expansion (DX) untuk ruang operasi RSUD Pagelaran Cianjur. Perancangan dilakukan menggunakan pemodelan tiga dimensi (3D) untuk menghasilkan desain yang akurat dan memudahkan proses fabrikasi. AHU dilengkapi casing double skin, cooling coil DX, electric heater, EC fan, sistem filtrasi (pre-filter, medium filter, dan HEPA filter), serta drain pan. Sistem dirancang untuk memenuhi temperatur 22 ± 2°C, kelembapan relatif 55 ± 5%, dan standar kebersihan udara ISO 14644-1:2015 Class 6. Hasil pengujian menunjukkan temperatur rata-rata 19,25°C dengan RH 59,96% pada pengujian pertama, serta 22,7°C dengan RH 57,1% pada pengujian kedua. Pengujian jumlah partikel pada enam titik menunjukkan seluruh konsentrasi partikel masih berada di bawah batas maksimum ISO 14644-1:2015 Class 6. Dengan demikian, AHU yang dirancang mampu memenuhi kebutuhan pengondisian udara ruang operasi sesuai standar rumah sakit.
