Colol is the centre of high-quality coffee production in Manggarai, NTT. Colol's arabica and robusta coffee won the title of best coffee in the 2015 coffee contest, organised by the Indonesian Coffee Exporters and Industry Association in collaboration with coffee research and Akao Jember. From 2017 until now, Robusta coffee exports to the Netherlands have continued, with a grand total of 94 tonnes. However, Colol Coffee is not widely known by people outside NTT, so this study aims to determine the marketing area of colol coffee outside NTT with the criteria of Accessibility, Market Potential, Logistics, Environmental Conditions, and Security, by considering 9 alternative regions. Multi-criteria decision making (MCDM) involves evaluating decision alternatives with multiple criteria that have different weights according to their importance. The research method uses Analytical Hierarchy Process (AHP) to determine the criteria weights and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) to analyse and rank the region alternatives based on their closeness to the ideal solution. The data collection technique uses the interview method with related parties, namely ASNIKOM managers who are decision makers and literature studies as a source of in-depth data that provides a theoretical basis to support the decisions taken. The results showed the highest priority value in the regions of Bali (0.7068), DKI Jakarta (0.5930), West Nusa Tenggara (0.5877), Central Java (0.5762), West Sumatra (0.5651), East Java (0.5298), North Sumatra (0.4284), West Java (0.4003), South Sumatra (0.3095).

Abstract

The use of the internet during the pandemic has increased significantly, one of the risks is cyber attacks. Where in the field of online marketing and sales they can sabotage logins. Collect story shop is one of the providers of photography services in the city of Makassar. Currently the process of ordering customer services comes to the office or orders via social media Instagram or WhatsApp so that it has several problems and has not been able to maintain the security and confidentiality of customer data. This study aims to keep the content of the message secret by changing the message to be difficult to understand when sent and unknown to people who have no interest. In this study, fingerprints are implemented for login security. Fingerprint is a technology that uses biometric verification, namely fingerprints, but when the smartphone does not have a fingerprint feature, the data will be secured using the Riverst Shamir Adleman (RSA) algorithm. The RSA algorithm is one of the public key algorithms that has the advantage of a high level of accuracy due to the difficulty of factoring prime numbers. Every data entered into the ordering application is encrypted using the RSA algorithm in the form of numbers stored in the database and will be decrypted again on the application's user interface display. The results show that fingerprints and RSA algorithms can help the process of securing customer data from the results of accuracy testing, so that the contents of secret messages are difficult to understand when sent and are not known by people who are not interested
