"Sejalan dengan meningkatnya popularitas kapal pesiar dalam beberapa waktu terakhir, beberapa rute baru telah dikembangkan demi menggaet ceruk pasar yang lebih luas dan lebih masif. Walaupun dalam 3 tahun ke belakang industri tersebut terdampak pandemi, namun menurut data, di seluruh dunia, industri kapal pesiar memiliki tingkat pertumbuhan tahunan penumpang sebesar 6,6% dari 1990-2019. Menyikapi hal ini, beberapa perusahaan pelayaran kapal pesiar gencar membuat dan melakukan kajian untuk membuat rute baru. Kebijakan ini juga merupakan salah satu cara perusahaan memanfaatkan kondisi pasar yang mulai berangsur membaik pasca pandemi. Sampai saat ini sudah ada total 8 armada kapal pesiar baru dari MSC Cruises yang akan dibangun dan siap berlayar di tahun 2023-2028. Namun nyatanya beberapa rute baru hanya menggunakan diversifikasi pelabuhan singgah dan destinasi di berbagai pelabuhan sebagai variabel. Maka dari itu, pemilihan rute merupakan hal yang krusial untuk dapat mengurangi biaya operasional yang tinggi, meminimalisir jarak tempuh serta konsumsi bahan bakar demi mengurangi jejak karbon dan polusi udara. Penelitian ini mengimplementasikan metode optimasi dengan menggunakan Travelling Salesman Problem, dengan algoritma Hamiltonian cycle. Dengan algoritma tersebut, harapannya dapat ditemukan jalur antar pelabuhan dari setiap trayek round-trip dari kapal MSC Cruises yang paling pendek dalam segi jarak. Penelitian ini bertujuan untuk menguji apakah trayek yang sudah ditentukan merupakan jalur paling pendek. Pada penelitian dengan judul Optimasi Pemilihan Rute Pelayaran round-trip Kapal Pesiar MSC Cruises menggunakan Hamiltonian Cycle, ditemukan adanya perbedaan jarak yang lebih dekat sehingga menghasilkan rute pelayaran round-trip yang efisien dan lebih hemat biaya.

With the increasing popularity of cruise ships in recent times, several new routes have been developed to capture a wider and more massive market niche. Even though in the past 2 years the industry has been affected by a pandemic, according to data, worldwide, the cruise ship industry has had an annual passenger growth rate of 6.6% from 1990-2019. In response to this, several cruise ship shipping companies are intensively making and carrying out studies to create a new route. This policy is also one way for the company to take advantage of market conditions which are starting to improve gradually after the pandemic. Until now, there are a total of 8 new cruise ships from MSC Cruises that will be built and ready to sail in 2023-2028. However, in fact, several new routes only use the diversification of transit ports and destinations at various ports as variables. Therefore, route selection is crucial to reduce high operational costs and minimize mileage and fuel consumption to reduce carbon footprint and air pollution. This study implements the optimisation method using the Traveling Salesman Problem, with the Hamiltonian cycle algorithm. With this algorithm, the hope is to find the shortest route between ports from each round-trip route for MSC Cruises in terms of distance. This study aims to test whether the route that has been determined is the shortest path. In a study entitled Optimizing the Selection of Round-trip Cruise Routes for MSC Cruises using the Hamiltonian Cycle to find a difference in closer distances resulting in an efficient and more cost-effective round-trip shipping route."

"Kronecker products are used to define the underlying Markov chain (MC) in various modeling formalisms, including compositional Markovian models, hierarchical Markovian models, and stochastic process algebras. The motivation behind using a Kronecker structured representation rather than a flat one is to alleviate the storage requirements associated with the MC. With this approach, systems that are an order of magnitude larger can be analyzed on the same platform. The developments in the solution of such MCs are reviewed from an algebraic point of view and possible areas for further research are indicated with an emphasis on preprocessing using reordering, grouping, and lumping and numerical analysis using block iterative, preconditioned projection, multilevel, decompositional, and matrix analytic methods. Case studies from closed queueing networks and stochastic chemical kinetics are provided to motivate decompositional and matrix analytic methods, respectively."

Informasi mengenai penggunaan energi listrik merupakan salah satu elemen penting dalam hal pengaturan distribusi jaringan listrik pada jaringan pintar skala kecil (smart micro grid). Selain itu informasi pemakaian energi listrik dapat membantu konsumen melakukan proses evaluasi pemakaian energi listrik untuk menekan biaya tagihan pembayaran listrik yang secara tidak langsung berpengaruh pada efisensi energi keseluruhan. Salah satu metode dalam proses pemantauan pemakaian energi listrik adalah Non-Intrusive Load Monitoring (NILM). Permasalahan utama dalam NILM adalah mengetahui peralatan-peralatan elektronik yang ada dan mengetahui konsumsi energi listrik masing-masing peralatan dengan hanya melakukan proses pengambilan data hanya dari satu titik yang terhubung dengan semua peralatan elektronik pada jaringan listrik. Berdasarkan hasil pengujian menggunakan dataset AMPds dan REDD, nilai akurasi terendah yang didapatkan adalah sebesar 96,69% pada semua pengujian yang dilakukan.

 


Information on electricity consumption is one of the essential elements in terms of regulating the distribution of electricity in smart micro grid. Besides, information on electricity consumption can help consumers carry out an evaluation process to reduce electricity bill costs, which indirectly affect overall energy efficiency. One method in the process of monitoring electricity consumption is Non-Intrusive Load Monitoring (NILM). The main problem in NILM is electronic disaggregation equipment that exists and determines the electrical energy consumption of each appliance by merely performing the retrieval of data from only one point connected with all the electronic devices on the electrical grid. Based on the results of tests conducted using the REDD and AMPds dataset, the lowest accuracy was 96.69% for all tests performed.
