Simple Project Management Software

My husband just recently used Trello, one of simple project management sofware, to manage tasks between his project members. For your information, he is programmer with mechanical engineering background. On the other day, I saw him downloading project management e-book. This is quite interesting behavior.

Two years ago, when I was working in Senoro Gas Development Project, one of my colleague, who are planning and schedule, usually used Primavera as project management tools. It was a quite professional and advance tools.

I was wondering, if maybe there are several simple project management software that I and my team can use. The software should be simple enough, easy to use, and easy to customize.

In this post, I want to share you several simple project management software and my experience trying them. Read More

My Little Trip to Yogyakarta Related to Project of The Year and Culinary Experience

Last week, I had a little trip to Yogyakarta related to this post. It was quite nice experience, despite of my role in this trip. Me and my team were supporting members of this meeting. If supplementary explanation is required, then we help.

This meeting was nice because I can witness how Plan of Development is prepared from A to Z and what was each topic about. Read More

Visiting Drinking Water Treatment Plant in Tirtawening

On December 2017, I got an opportunity to visit drinking water treatment plant in Tirtawening, Bandung, which is near my college. It was a very amazing experience, because this is my first experience visiting water treatment plant. And also, experience like this is very rare after I entered working environment.

This site visit is actually a part of water treatment plant training. I will share you about this training in different post.

Drinking water treatment facility in Tirtawening is actually the biggest one in Indonesia. It processed 2000 liter/second water, from two trains (rate of each trains is 1000 liter/second). 1900 liter/second water is sent to customers and 100 liter/second water is own used. Read More

LPG vs Natural Gas

In Indonesia, people use LPG or natural gas to cook foods or to produce hot water for bath. In my city, natural gas is less popular than LPG. However, in other area, people are starting to switch from LPG to natural gas. It is because the government program to utilize it as city gas.

Let’s take a closer look at which one is better from a cost, usability, and safety point of view. Read More

Pre-FEED is My Second Project of The Year

Pre-FEED (Preliminary Front End Engineering Design) is my second project of the year. This is not the first time for me, especially Pre-FEED of oil and gas surface facility. However, the complexity is completely different from the previous one. I can say, this one is much more challenging.

The Pre-FEED I worked on is for Plan of Development (POD). Through POD, SKK Migas (Indonesia Special Task Force for Oil and Gas) along with KKKS (Cooperative Contract Contractor) are able to produce hydrocarbon reserve (which is national asset) very well, by considering both technical and commercial aspect, so that it will give benefit for Indonesia and fair benefit for KKKS.

How can Pre-FEED has something to do with POD? Read More

Small Scale Geothermal Power Plant is My Project of the Year

It’s been a while since the last post I wrote in this blog. I always, always want to have a fresh start and be consistent in this way. So, here I am, updating this blog! Yeay!

I’ve learnt many things during this year. In this very first post of the year, I want to share you what projects I have done and on-going at the moment. Hopefully you can enjoy it.

At the beginning of the year, I had a small scale geothermal power plant. It was my very first geothermal power plant project. So, I was very excited and of course… worried. Read More

Pneumatic Control and Electric Control Comparison

As you may already know, control is one of the most important part in plant. To ensure that every operating condition is controllable, we install many control valves that connected to a kind of process parameters, such as pressure, temperature, level, or phase interface. Control of parameter can be done by pneumatic control or electric control.

The availability of pneumatic control has declined, except in one area: gas pipeline industry. The main reason is pressurized gas is available to run the controller. It is essentially free and it does not introduce any additional hazard. Read More

Design of Shell and Tube Heat Exchanger – Tube Side Construction

In my previous post, design of shell and tube heat exchanger – layout design, I shared how to select fluid allocation, which one should be in tube side and which one should be shell side, general rule for allowable fluid velocity, pressure drop, and temperature approach. This post will be the continuation of design of shell and tube heat exchanger series, which specifically explain about construction detail in tube side.

Want to learn from the beginning?
Read my first post about step-by-step design of shell and tube heat exchanger. Still curious? Read my second about about layout design of shell and tube heat exchanger.


This is mind map of this topic.

My First Javascript Online Calculator – Instrument Air and Compressor Sizing

For a long time, I want to post something more advance in this blog. I always want this blog like or I want to make online calculator just like did.

Due to my limitations, at this point I cannot create online calculator. To compensate that, I tried to make useful spreadsheet.

But, today I did it! I made my first online calculator, which is instrument air sizing calculator. Please click this link to access to instrument air and air compressor online calculator. I hope you find it useful.

It is better for you to check two of previous post related with the calculator. Calculation basis used in this calculator is based on those two post.

Read Sizing of Compressor and Instrument Air Capacity

Read Spreadsheet of Air Compressor and Air Dryer Calculation


I already replaced spreadsheet attached in this post : Spreadsheet of Air Compressor and Air Dryer Calculation. So you can trace how the calculation works.
