 Halooo Sobat Engineer. Bagi para engineer utility di industry manufactur atau pabrik maupun facility di Highrise building mungkin sering mendengar ataupun bahkan sering mendapatkan komplain berkaitan dengan Air Handling Unit atau sering disebut dengan AHU. Berikut sedikit sharing saya bagaimana sih AHU itu dibuat, parameter apa saja yang dipakai pada saat membuat AHU. Berdasarkan pengetahuan yang saya dapat, berikut adalah beberpa referensi jika kita membuat sebuah AHU : 1. BS EN 1886: 2007 – Ventilation for Building. Air Handling Unit. Mechanical Performance 2. BS EN 13053: 2006 – Ventilation for Building. Air Handling Unit. Rating and Performance for unit’s components and sections 3. ANSI/AHRI 1350: 2014 – Mechanical Performance Rating of Central Station Air Handling Unit Casings Dengan parameter yang biasa dilakukan testing sebagai berikut : 1. Mechanical Strengh 2. Air Leakage 3. Thermal Transmittance 4. Thermal Bridging 5. Acoustic Insulation 6. Air filter bypass leakage Untuk le

 Sekarang saya akan akan berbagi sedikit tentang Dasar Dasar penggunaan alat listrik seperti : 1. Tang Ampere / Ampere Clamp 2. Multitester / Digital Multitester / Avometer 3. Digital Earth Tester / Grounding Tester 4. Insulation Tester / Test Megger Dalam Alat ukur tersebut kita bisa melakukan beberapa pengukuran seperti : 1. Pengukuran tegangan 2. Pengukuran Kuat Arus/Ampere 3. Pengukuran Resistan/Tahanan 4. Pengukuran Kapasitor / Kapasitansi Dengan kita bisa menggunakan alat alat tersebut, terutama temen temen yang baru lulus atau fresh graduate, maka siap untuk bekerja/bergabung dengan perusahaan-perusahaan saat ini. Apalagi kalau kita bisa melakukannya menggunakan nilai standar lalu dibandingkan dengan hasil aktual. Dimana kita dituntut untuk menganalisa suatu pengukuran apakah normal ataupun tidak.  Untuk lebih detailnya bisa lihat di youtube kami Dasar Dasar Kelistrikan 2 Lalu download materi detail nya di  Google Drive BASIC ELECTRIC 2 If you like these article, please like, sh

 Now i would like to share about Oxygen generator basic system using PSA Method. Do you ever heard about Oxygen Generator or Oxygen Concentrator? Which this machine we can use for produce oxygen in order medical treatment or for other matter in industrial process. Now, i would like to share the Oxygen Generator at industrial process. Picture at above only for installation sample, the user can impelement the installation depend of their budget or other consideration. If we have plan to install oxygen generator at our company, we have to consider : 1. Budget/Cost 2. Gas Purity 3. Machine Placement 4. Maintenance  5. Long term plan after we consider the things at above, we have to prepare for design of Oxygen generator will use : 1. Destilation Method, Or 2. PSA method If we consider about Purity and that things is very essential. We have to choose Destilation method. If we choose PSA method, the purity will be lower than destilation method. For more detail about PSA method, you can dowlo

 Now, i would like to share about Boiler or Steam Devices. Did you ever heard about it? or Did you curious with Boiler? Based on our experience with Boiler, Currently the Boiler Package was High technology Used especially related with Safety Device. So, the Boiler Operator can operate the machines without worries or affraid. Picture at above is Boiler Package which is common use on Manufacturing process. If your industry such as Glass Industry, Power Plant or Refinery Plant it will be use Site Boiler.  See at below So, what kind of main component in the Boiler : 1. Furnace/Burner 2. Safety Valve 3. Steam Drum 4. Control Panel 5. Water Pump 6. Sight Glass 7. Superheat ( Site Boiler ) 8. Economizer ( Site Boiler ) Commonly the Boiler have 2 type based on the Tube Fluids, such are : 1. Fire Tube ( Inside the Tube is Fire  - Mostly at Package Boiler ) 2. Water Tube ( Inside the Tube is Water - Mostly at Site Boiler ) Which Commont industry use it : 1. Fire Tube ( Food & Beverage, Autom

Do you ever heard about Pharmaceutical HVAC is different with other industries? Actually for HVAC system at Pharmaceutical industry not too much different with others industry, just need additional several device have to install and also for pharmaceutical industry have to comply with Drug regulation either Company regulation or Government regulation and depend of product will be sell it.   So, what kind of system/device/equipment have to install at Pharmaceutical Industry : 1. Dehumidifier 2. Humidifier 3. Heating Coil 4. Dust Collector 5. Exhaust Fan Not only device/equipment have to install, but we also have to do several activities related with Pharmaceutical HVAC such as : 1. Verification & Qualification 2. Calibration We will explain, what we have to do about Verification & Qualification. A. Verification & Qualification Is Activities for ensuring the HVAC system suitable with user requirement and hvac system performance is stable and confirmity. During verification &a

  Do you ever hear Split AC ? mostly all of the people just know only Split Wall AC. Now, i will share about what kind of Split AC type. If you Never saw the others split AC or you had saw split ac but never knew the name, please read this article more getting more the knowledge. Type of Split AC : 1. Split Wall AC 2. Split Duct 3. Split Ceilling Cassette 4. Split Standing Floor Please see at the picture below  So, what the different from each type ? please see at the Picture below : then, now i will share what the common trouble if we using Split AC for operational or Residential. if you are wanna learn to getting new knowledge about AC Split Wall, Duct, Ceiling Cassette or Standing Floor.  You can download our material by Google Drive  AC Split  ( Free of charge ) If you like these article, please like, share and comment. also please follow & connect our social media in linkedin : Arifin Hidayat _ Linkedin Youtube Channel  Sharing Knowledge Also please visit to our article : Read

Now i will sharing about Python.  I here i will sharing python for Data Scientist which is Python capable for create statistic data.  Please look at the picture below : The Statistic data not only using Excel, Minitab or SPSS application, but you can use Python for statistic data. Before we would to use Python, we have to prepare the software and libraries : 1. We have to install application anaconda navigator.    You can download in  Anaconda.com   ( Open Source and Free ) 2. After download and Install, you can running Anaconda Navigator 3. Then please check at tab environment, then colomn installed, Pandas and Seaborn was installed or not?  if Libraries displayed such as the picture above. your application has libraries installed. If not displayed, you have to install libraries. Running command prompt Anaconda Powershell Prompt                                   1. Write " conda install seaborn" then press enter button                                   2. if have question fo
