Abstract

The aim of this research is to conduct a study of the ELECTRE method as a support in decision making to obtain the best decision alternative from a number of decision alternatives. This research also aims to determine which bank alternative is the best alternative for stock investment using the ELECTRE method. The data used is secondary data obtained from bank financial reports for 2023 which is an alternative. The alternative banks used consist of 4 large banks in Indonesia. Meanwhile, the criteria used consist of 5 financial ratios, namely Return on Assets, Return on Equity, Price to Book Value, Price to Earning Ratio, and Debt to Equity Ratio. The results of this research show that BBNI shares are the best alternative bank for stock investment. The conclusion that can be obtained is that the ELECTRE method is effective for use as a support in decision making because the decision alternative that will be obtained is the best decision alternative that has a level of suitability above the suitability threshold and also at the same time has a level of nonconformity below the nonconformity threshold.

Abstract

Sibolangit Village is known as a tourist village because it has a lot of natural potential that can be developed into a tourist destination in Deli Serdang Regency. Some of the tourism potential in Sibolangit Village includes the Taman Wisata Alam Sibolangit, Tangga Seribu, Uruk Sikuda-kuda, Taman Pekabar Injil Pertama GBKP, Goa Sejarah, Pemandian Alam Sibolangit. However, the management of tourist attractions in Sibolangit Village is not yet optimal because human resources in terms of expertise and skills in the field of tourism are still minimal, causing the tourist attraction to be unattractive and ultimately the number of visitors does not experience a significant increase. Carry out community service activities by holding training to improve skills in managing tourism businesses, marketing and customer service in Sibolangit Village. This training also covers aspects of sustainability, making the community the guardian and custodian of local heritage. Apart from that, a Tourism Awareness Group (Pokdarwis) will be formed as a representative of the Sibolangit Village community in developing tourism.

Abstract

Seiring semakin mudahnya masyarakat untuk bepergian dan pesatnya perkembangan teknologi digital, masyarakat lebih memilih untuk memesan tiket secara online. Hal ini mendorong banyak e-commerce penjualan tiket online bermunculan dengan caranya masing-masing untuk menarik pelanggan dan menjaga loyalitas pelanggan. Diperlukan strategi optimal untuk mencegah perpindahan pelanggan. Menurut survei, Traveloka dan Tiket.com adalah e-commerce yang paling banyak digunakan. Kedua e-commerce tersebut saling bersaing untuk mencari dan mempertahankan pelanggannya. Tujuan dari penelitian ini adalah untuk mengetahui strategi pelanggan optimal dalam persaingan e-commerce penjualan tiket pesawat yaitu Traveloka dan Tiket.com menggunakan teori permainan serta untuk mengetahui probabilitas perpindahan pelanggan di antara kedua e-commerce tersebut dengan metode rantai markov. Dalam permainan dua pemain jumlah nol terdapat dua strategi yaitu strategi murni dan strategi campuran, namun apabila kedua strategi itu tidak menghasilkan titik pelana maka akan digunakan metode alternatif. Pada penelitian ini, akan digunakan metode dual simpleks. Penelitian ini menghasilkan solusi optimal dengan menggunakan metode dual simpleks dimana bagi kedua e-commerce strategi optimalnya adalah strategi harga termurah dan strategi banyaknya metode pembayaran, dengan probabilitas perpindahan Traveloka sebesar 0,4817 dan Tiket.com sebesar 0,5183.
