Sistem pendinginan muatan (cooling down) pada kapal LPG berfungsi
untuk merubah muatan dalam tangki yang berbentuk uap (vapour) kembali
menjadi bentuk cair. Sistem ini bekerja menghisap uap (vapour) dari tangki untuk
kemudian ditekan (compress) hingga tekanan dan suhunya meningkat. Kemudian
vapour yang telah dimampatkan ini akan dikondensasikan, hasil kondensasi
berbentuk cairan ini atau yang disebut dengan kondensasi akan dialirkan kembali
ke dalam tangki dengan system spray sehingga dapat menurunkan temperatur dan
tekanan dalam tangki. Dengan ini maka kestabilan temperatur dan tekanan dalam
tangki dapat dijaga. Kemudian pada saat song loaded voyage akan sangat besar
kemungkinan timbulnya perubahan pada bentuk muatan, yang disebabkan oleh
tidak stabilnya temperatur dan tekanan dalam tangki muatan. Dalam hal
kestabilan temperatur dan tekanan tangki sangat erat kaitannya dengan proses tank
cooling down, dimana metode yang diterapkan pada sat proses berlangsung harus
efektif dan efisien. Hal inilah yang membuat penulis mengambil judul “Upaya
Penanganan Muatan Dengan Tank Cooling Down Guna Menghindari Berubahnya

Metode Penelitian yang digunakan oleh penulis dalam penyampaian
masalah adalah metode deskriptif, kualitatif untuk menggambarkan dan
menguraikan objek yang di teliti. Dalam penelitian skripsi ini, penulis,
menggunakan macam metode analisis data yang mana akan di bahas yaitu reduksi
data, penyajian data, dan menarik kesimpulan.
Dari pembahasan permasalahan diatas bahwa penyebab timbulnya
perubahan bentuk muatan disebabkan oleh tidak tercapainya kestabilan
temperature dan tekanan di dalam tanki muatan. Berdasarkan analisa dan
pembahasan diambil kesimpulan bahwa penyebab timbulnya masalah tersebut
disebabkan oleh kurang tepatnya perwira dalam mengambil metode tank cooling
down dan kurang berfungsinya beberapa spray nozzle yang ada pada tangki
karena faktor usia dan kurangnya perawatan pada spray nozzle. Di atas kapal
perwira bertanggung jawab penuh selama proses tank cooling down dikarenakan
dari keseluruhan proses pelaksanaan pendinginan muatan kegiatan akan tertumpu
pada ruang kompresor yang dalam hal ini operator di atas kapal dituntut agar
dapat mampu untuk menggunakannya semaksimal mungkin, sehingga menjadi
tanggung jawab tanggung jawab perwira di atas kapal

System cooling down on LPG ship serves to change the charge in the tank in
the form of steam (vapour) back into a liquid form. This system works with steam
inhalation (vapour) from the tank and then pressed to the pressures and
temperatures are rising. The vapour is then compressed, this would have been
condensation, the result of condensation liquids or condensation will be called
streamed back into the tank with spray system so that it can lower the temperature
and pressure in the tank . With the stability of the temperature and pressure in the
tank can be maintained. Then at the moment the song loaded voyage will very
likely change in the incidence of this form of charge, caused by not stable
temperature and pressure in the tank the charge. In terms of the stability of the
temperature and pressure of the tank is closely associated with the process of
cooling down the tank, where the method is applied to the sat process must be
efficient and effective. It's what makes the author took the title of "the efforts of the

Abstract
Drimys beccariana Gibbs, a plant species renowned for its pharmacological properties, has shown potential as an antimalarial agent. Understanding its mechanism of action against malaria parasites through interaction with key receptors and enzymes is crucial for drug development. This study seeks to elucidate the mechanism of Drimys beccariana Gibbs as an antimalarial agent by investigating its interactions with several target receptors and enzymes involved in the malaria parasite’s life cycle. Molecular docking, employing structure-based drug design principles, was utilized to simulate the binding interactions between compounds derived from Drimys beccariana Gibbs and specific target receptors/enzymes crucial for malaria parasite survival. The docking studies revealed promising interactions between the compounds derived from Drimys beccariana Gibbs and key receptors/enzymes associated with malaria, including Triose-phosphate isomerase, Plasmepsin II, lactate dehydrogenase, and enoyl-acyl-carrier protein. Compounds 5,3’-dihydroxy-7,4’-dimethoxyflavone and 5,7-dihydroxy-4’-methoxyflavone exhibited significant binding affinity and potential inhibitory effects across multiple targets, suggesting their candidacy for further investigation as antimalarial agents. 5,3’-dihydroxy-7,4’-dimethoxyflavone and 5,7-dihydroxy-4’-methoxyflavone have considerable potential inhibition of receptors/enzymes associated with malaria
Energy Management System for PV-Battery Integrated Module
No full textTransition from fossil fuels to renewable sources is desired by both developed and developing countries due to the environmental concern and rapid technological developments. Governments, consumers, and investors have seen the prospect of Photovoltaic (PV) as a prominent technology to fulfill the electricity demand. For the residential-scale PV system,costs of the PV module(s) and the BoS (Balance-of-System) are usually the issue that discourage the consumers from installing PV system in their households. To tackle this issue, the concept of PV-Battery Integrated Module (PBIM) is developed. The operations of the PBIM are similar with typical operations of PV-battery system, which are controlled by the energy management unit. Energy Management System (EMS) is responsible for ensuring the safety of the electrical components and controlling the system operations to make it efficient. Therefore,implementing the suitable EMS is an integral part of establishing the PBIM system.This research aims to implement a power flow management for the PBIM system to perform two energy management strategies, namely peak shaving and off-grid self-consumption. To achieve that goal, this research focus on selecting the PBIM system architecture, implementing control system and power flow management, and analyzing PBIM system performance on the applications of peak shaving and off-grid self-consumption strategies. Two case studies are introduced in this thesis, namely off-grid PBIM in Cambodia and grid-connected PBIM in the Netherlands.The chosen system architecture for the PBIM is the DC couple architecture. The PBIM system consists of one PV module, one unidirectional boost converter to perform MPPT and curtail operation, one bidirectional buck-boost converter to handle charging and discharging operation, an inverter to connect the PBIM with an AC load, and a battery bank. There are seven modes of operation in the PBIM system, which are utilized to perform peak shaving and off-grid self-consumption strategies.For the off-grid PBIM in Cambodia, a 265Wp module and 8 batteries are used. The PV curtail operation is performed mostly during dry season, due to high irradiance. The LLP during rainy season (4%-7%) is much larger than the LLP during dry season (1%-3%), due to big difference in the irradiance between those two seasons. The total LLP for one year operation is 2.6%.For the grid-connected PBIM in The Netherlands, a 265Wp module and 8 batteries are also used. The peak shaving is performed in this case, hence the battery is being charged during off-peak hours, and the load is supplied by the grid. During peak-hours, the load is supplied by the PV, battery, and the grid. For one PBIM, the system autarky can only a maximum of 16%, hence multiple PBIMs are required to increase the PBIM system autarky for the grid-connected PBIM in the Netherlands.Electrical Engineering | Sustainable Energy Technolog
