Abstract

Websites used for tourism services process personal and transaction information, making security evaluation important to reduce the risk of misuse and data exposure. This study implements security improvements on the Alfarouq Tour Travel website based on vulnerability findings identified using OWASP Zed Attack Proxy (ZAP). The research uses an applied experimental approach consisting of an initial security scan, classification and analysis of findings, planning and implementation of remediation, re-scanning, and comparison of conditions before and after remediation. The initial scan using OWASP ZAP 2.16.1 on 25 April 2025 found no High-risk alerts, but identified three Medium-risk alert types with 57 instances: Absence of Anti-CSRF Tokens (1), Content Security Policy Header Not Set (30), and Missing Anti-clickjacking Header (26). Remediation was implemented through CSRF token protection and request-flow adjustment, Content Security Policy configuration, and X-Frame-Options together with the frame-ancestors directive. The re-scan on 30 December 2025 showed that all three Medium-risk alert types were no longer detected, reducing Medium instances from 57 to 0. Six Low-risk and six Informational alert types remained. The findings indicate that remediation based on ZAP results met the study’s success indicator for the three targeted Medium-risk findings within the tested scope, while further assessment is still required for residual findings and system areas not reached by the scan.

Abstract

Persaingan harga merupakan tantangan bagi UMKM jasa laundry yang menawarkan layanan relatif sama. Penelitian ini menganalisis strategi persaingan harga antara dua UMKM laundry di Martubung, Kota Medan, dengan pendekatan teori permainan. Data primer diperoleh melalui observasi dan wawancara: Laundry A menetapkan harga Rp25.000 per 8 kg dengan sekitar 20 pelanggan per hari, sedangkan Laundry B menetapkan Rp20.000 per 8 kg dengan sekitar 30 pelanggan per hari dan program gratis satu kali cuci setelah sepuluh kali pencucian. Model permainan dua pemain dengan tiga strategi harga (rendah, sedang, tinggi) disusun dan dikalibrasi pada data lapangan. Pada Model 1 (payoff jumlah pelanggan, jumlah pasar tetap 50 pelanggan per hari), nilai maximin dan minimax sama-sama 25 sehingga terdapat titik pelana pada kombinasi harga rendah–harga rendah. Namun, harga rendah dalam model ini mendominasi secara mekanis karena payoff tidak memuat harga; pada kondisi tersebut Laundry A hanya mempertahankan pendapatan kotor Rp500.000 per hari dengan beban pelanggan 25% lebih banyak. Uji sensitivitas Model 2 (payoff pendapatan) menghasilkan kesimpulan yang berbeda: kombinasi harga rendah–harga rendah bukan keseimbangan Nash. Hasil ini menunjukkan bahwa rekomendasi strategi harga bergantung pada definisi payoff, sehingga penetapan harga aktual perlu didukung data biaya, margin, kapasitas, dan elastisitas permintaan.
