Abstract

Penelitian ini membahas permasalahan Multiple Traveling Salesman Problem (mTSP) dengan pendekatan single depot berbasis penugasan, dengan biaya perjalanan antar node dinyatakan sebagai bilangan fuzzy trapezoid. Tujuan utama penelitian ini adalah meminimalkan biaya perjalanan dalam pengambilan deposit (Deposit Carrying) dari kantor pusat ke cabang-cabang Bank Mandiri di Pekanbaru. Formulasi yang disusun mencakup penyesuaian bobot biaya menjadi bilangan fuzzy trapezoid, yang kemudian dikonversi menjadi nilai crisp menggunakan Ranking Score Method (RSM). Kasus ini melibatkan 21 node (1 kantor pusat dan 20 cabang), dengan batas atas dan bawah kunjungan per node untuk memastikan efisiensi penjadwalan kru. Hasil optimasi menunjukkan bahwa biaya minimum yang diperlukan untuk menjangkau seluruh cabang adalah sebesar Rp192.943,5 menggunakan kendaraan operasional berbahan bakar pertamax. Penelitian ini menunjukkan efektivitas model mTSP berbasis fuzzy dalam meminimalkan biaya perjalanan dan memberikan solusi yang relevan bagi industri perbankan, khususnya dalam pengelolaan operasional yang melibatkan ketidakpastian biaya

Abstract

Incidents of violence among students, particularly those involving groups operating beyond the reach of law enforcement, continue to occur frequently. The police must implement proactive preventive measures to avoid such incidents, as these behaviors contradict the norms that students are expected to uphold. The importance of appropriate handling of students involved in crime and violence, particularly from a law enforcement perspective, is highly emphasized. This study addresses the following problems: what are the factors that cause group violence committed by students within the jurisdiction of the Pancur Batu Police Sector; how is the legal regulation regarding criminal acts of violence committed by minors; and what efforts are being undertaken by the police in addressing the issue. This research is an empirical legal study. The data analysis applied in this research follows a qualitative approach. The results conclude that the occurrence of student brawls is not only driven by personal desire but is also heavily influenced by peer pressure, which significantly affects one's social interactions and behavior. Legal provisions governing violent crimes committed by students can be found in the Indonesian Criminal Code, particularly Articles 170, 351, and 406, as well as in Law Number 35 of 2014 on Child Protection. The efforts made by the Pancur Batu Police in addressing group violence among students include both preventive and repressive approaches.
