Abstract

Kadar H2S pada amine contactor 135-V-06 PT. XYZ Ujung Pangkah meningkat melewati rentang operasional sebesar 4–5 ppm pada beberapa waktu tertentu. Kondisi ini memerlukan sistem diagnosa yang dapat mendiagnosa kondisi riil dan memberikan informasi keputusan aksi yang perlu dilakukan. Penelitian ini mengusulkan sebuah rancangan sistem diagnosa menggunakan rule-based ta berbasis data riil yang direkam. Data input dan output disusun dalam bentuk lookup table berukuran 12 x 10 x 6 yang berisi data record dengan variabel flowrate sour gas, temperature lean amine, flowrate lean amine, dan kadar H2S. Analisa data terhadap kondisi riil diketahui variabel yang paling berpengaruh adalah temperature lean amine. Upaya selanjutnya dalam menjaga kestabilan kadar H2S diajukan desain sistem pendingin sepanjang jalur pipa inlet lean amine. Sistem pendingin bersifat on/off yang hanya akan melakukan pendinginan ketika kadar H2S diatas rentang operasional. Sistem pendingin merupakan double pipe cooler dengan air pendingin yang menyelimuti jalur pipa inlet lean amine dengan rise time pendinginan sebesar 131,83 s. Sistem hasil rancangan divalidasi dan ditunjukkan bahwa sistem diagnosa mampu menjalankan sistem pengendalian temperatur dan menjaga kadar H2S didalam range operasional.

Electrical energy is one of the most important and vital human needs that cannot be separated from daily needs. Batteries are electrical energy storage devices obtained from chemical reactions. In general, the batteries found in portable electronic equipment are lithium ion batteries. This type of battery is rechargeable for continuous use. The process of recharging the battery in this study uses a constant current-constant voltage (cc-cv) charging system which is useful for controlling the charging voltage and current so that it does not overcharge, where the initial charging condition uses a constant current charging method. The components of this battery charger consist of two stages, namely constant current using a buck converter circuit, and at constant voltage stages using a voltage regulator circuit. In this study using a control system based on fuzzy logic algorithms, so with this implementation it is expected that the battery charger can work well in controlling battery charging. The system design and testing carried out include buck converter, fuzzy logic algorithm, voltage sensor, current sensor, and charger system as a whole. The results of testing and designing the system, charging this battery produce a voltage of 12.6V and a current of 2.5A. Charging will be full and stop when the current flowing decreases and cut off at the flow of 100 mA.
