Abstract

Pelabuhan petikemas tak lepas dari kesibukan proses bongkar muat barangnya, dengan selalu adanya kapal yang datang dan pergi membawa muatan. Proses bongkar muat tersebut menggunakan alat berat yang bahan bakarnya yang kurang ramah lingkungan. Saat ini pelabuhan petikemas di seluruh dunia tengah menerapkan prinsip konsep pelabuhan hijau ramah lingkungan (green port). Segala macam alat baik industri maupun produksi sebisa mungkin dicarikan solusi agar dapat mengurangi jumlah polusi dan limbah. Maka muncullah adanya konsep bahan bakar yang dapat diperbarui, seperti matahari, air, angin, dan sumber daya alam lain yang dapat menunjang terciptanya konsep pelabuhan petikemas yang ramah lingkungan. Alat berat seperti container crane di pelabuhan menjadi alat berat utama dalam proses distribusi muatan kapal. Crane yang beroperasi dengan suplai listrik dari PLN dan generator diesel pada umumnya, pada penelitian ini dicoba diteliti dengan percobaan suplai menggunakan energi sumber daya alam yang dapat diperbarui, seperti panel surya. Dengan mengamati dan memodelkan sistem kelistrikan container crane, khususnya skema one-line diagram-nya, pada penelitian ini dioperasikan menggunakan pemodelan berbasis simulasi ETAP. Kondisi dari suplai energi listrik panel surya yang memiliki karakteristik tegangan, frekuensi, dan daya yang berbeda dengan energi listrik dari PLN dan generator diesel, dicoba untuk dibandingkan dan dianalisa pada penelitian ini. Studi kasus kali ini hanya fokus pada aliran daya yang terdapat dalam sistem kelistrikan container crane. Baik itu efisiensi tiap motornya, rugi daya selama proses transmisi, hingga tegangan jatuh yang terjadi selama proses distribusi tegangan. Setelah proses pemodelan dan simulasi telah dilakukan, didapatkan hasil bahwa suplai panel surya (PV) cukup bisa untuk digunakan sebagai sumber daya untuk suplai sistem kelistrikan container crane. Pada suplai PV, disimulasikan menggunakan output tegangan hasil inverter sebesar 0,38 kV. Simulasi dengan suplai PV ini menghasilkan efisiensi daya yang lebih rendah dari suplai PLN dan generator, serta tegangan jatuh yang lebih tinggi dari suplai PLN dan generator. Namun, pada tiap skenario suplai PV, efisiensi daya dan tegangan jatuhnya masih dalam batas IEC dan IEEE. Contohnya pada saat skenario motor gantry, efisiensi daya sebesar 94,44%, dan tegangan jatuh 0,274%. Lalu pada skenario motor boom, efisiensi daya 94,43% dan tegangan jatuh 0,457%. Pada skenario motor trolley, efisiensi daya 94,44% dan tegangan jatuh 0,374%. Pada skenario motor hoist, efisiensi daya 94,76% dan tegangan jatuh 0,269%. ============================================================================================= Container ports can’t be separated from their loading-unloading process with container ships that never stops come and come again to load or unload their containers or cargos of goods. Those loading and unloading processes are still using heavy equipment that still consuming less eco-friendly fuels. Nowadays, container ports all around the word are still implementing the principle concept of “green port”. All the heavy equipments in port, like product equipment or industrial equipment, are expected to get some solutions to reducing its polution and waste of fuel. So, therefore came a new concept of using renewable fuels, its like solar energy with solar panel or wind energy, or any natural resources that can supports the realization concept of “green and eco-friendly container port”. Heavy equipment, like container crane, in port is becoming the main equipment that contributes and operates during the loading-unloading processes. Container cranes that usually operated with consuming fuel from State Electricity Company (PLN) and diesel generators, in this research, are getting studied with new renewable energy supply, solar panels. According to container crane’s one-line diagram of electricity scheme,the its one-line diagram is modeled into simulation application, its called ETAP. Solar panel’s condition and characteristics (such as voltage, frequency, and output load), that have any differences with supply electric energy from State Electricity Company(PLN) and diesel generators, are being compared and analyzed in this research. Research focus of study is only on its loadflow on this container crane electric system. Otherwise, such as its electric motor’s load efficiency, loss power, and voltage drop during its power and voltage distribution are being studied too. After doing process of modelling its one-line diagram into ETAP, then its simulated per scenario. Some results of this research are, solar panel supply is still works and recommended for supplying electricity demand of one container crane. Some notes required in this study are, the voltage output from inverter are 0,38 kV. Other results are, this type of supply is producing fewer load efficiency higher voltage drop if being compared into supply from State Electricity Company(PLN) and diesel generators. But, in all scenarios being simulated, solar panel supply has load efficiency and voltage drop that is still in between among the minimum standards from IEEE and IEC. The example is from gantry motors scenario, its load efficiency is 94,4% and voltage drop only 0,274%. Then, from boom motor scenario, its load efficiency is 94,43% and voltage drop only 0,457%. From trolley motor scenario, its load efficiency is 94,44% and voltage drop only 0,374%. Last, on hoist motor scenario, its load efficiency is 94,76% and only has 0,269% of voltage drops.
