Abstract

Transportasi adalah salah satu permasalahan dalam riset operasi yang berfungsi mengelola distribusi secara optimal dari sumber penyedia barang menuju tempat tujuan yang memerlukan barang (Simbolon dkk., 2014). Masalah transportasi yang memiliki beberapa fungsi tujuan disebut Multi-Objective Transportation Problem. Fuzzy Programming menerapkan teori himpunan fuzzy untuk masalah multikriteria dalam membuat keputusan. Fungsi keanggotaan berperan memetakan data ke dalam nilai keanggotaan fuzzy di [0,1] dalam fungsi tujuan. Tujuan penelitian ini mengembangkan model optimasi distribusi air bersih di PDAM Surabaya menggunakan Multi-Objective Transportation Problem untuk mencari waktu dan biaya optimal. Hasil penelitian menunjukkan bahwa fungsi objektif waktu ( ) yaitu Minimumkan: , menghasilkan waktu optimal sebesar 8 jam 23 menit 6 detik dan fungsi objektif biaya ( ) yaitu Minimumkan: , menghasilkan biaya optimal sebesar Rp3.627.443,876. Kata Kunci: Metode Transportasi, Multi-Objective, dan Distribusi.

Abstract

The aim of the community service to provide training and mentoring in educational data processing using Microsoft Excel. The community service activity involves teachers as participant from Sekolah Indonesia Bangkok, Thailand. The activities are carried out in phases which include planning, coordination with partner school, obtaining necessary permits, developing training module, conducting the training, and evaluating the outcomes. The training consisted of four stages which are a pre-test, training material presentation, a question-and-answer session, and a post-test. The output of the community service was a Microsoft Excel training module that cover both the technical aspects of the software and simple practical application. The effectiveness of the training was evaluated based on the results of the pre-test and post-test. The result showed a significant improvement regarding to participants’ understanding, as evidenced by the increase in the number of correct answers and the average percentage between the pre-test and post-test. The average percentage of correct answers of the participants before the training was around 34% and after the training about 52%. Meanwhile, the average percentage of the pre-test is 62,27% and post-test is 87,91%.
