Abstract

Teknologi informasi telah banyak diterapkan di berbagai perusahaan, salah satunya PT XYZ yang telah menerapkan sistem informasi penjualan atau BEI sebagai otomatisasi proses bisnis perusahaan. Namun pada praktiknya manajemen risiko sistem informasi BEI belum diterapkan dengan baik, masih terdapat kendala dan insiden pengelolaan. Penelitian ini bertujuan untuk menganalisis manajemen risiko sistem informasi ISX dengan menggunakan framework FMEA (Failure Mode Effects and Analysis). FMEA dapat mengidentifikasi risiko berdasarkan tingkat keparahan suatu kejadian, seberapa sering kejadian tersebut terjadi, dan seberapa tinggi tingkat deteksinya. Dari variabel-variabel tersebut akan dihasilkan Risk Priority Number (RPN) yang dapat menentukan prioritas risiko atau permasalahan yang paling kritis. Hasil penelitian ini menunjukkan bahwa sistem ISX mempunyai 2 risiko dengan tingkat sangat tinggi, 1 risiko dengan tingkat tinggi, 1 risiko dengan tingkat menengah, 21 risiko dengan tingkat rendah, dan 5 risiko dengan tingkat sangat rendah. Risiko yang berada pada tingkat yang sangat tinggi dan tinggi merupakan risiko yang diprioritaskan dan perlu mendapatkan tindakan dan pengendalian risiko.

Abstract

The development of personal potential, understanding the urgency of science, and values of loyalty to the roles and responsibilities of students are important components in shaping character and individual competencies in higher education. This study aims to examine the effectiveness of a student leadership development training programme integrated with an approach that strengthens personal potential, mastery of science, and values of loyalty in improving the cognitive and affective competencies of participants. The research method employs a quantitative approach with a one-group pre-test and post-test design involving 90 students as respondents. Evaluation instruments consisting of pre-tests and post-tests were analysed using the Kolmogorov-Smirnov normality test, paired sample t-test, and one-sample t-test. The analysis results indicate that the data is normally distributed (p = 0.200), there was a significant difference between pre-test and post-test scores (t = -9.401, p = 0.000), and post-test scores were also significantly higher than the reference value (t = 3.933, p = 0.000), with an average increase of 19.83 points. These findings indicate that training that integrates aspects of self-potential, knowledge, and student loyalty values is proven to be effective in significantly improving understanding and skills.

Abstract

Online motorcycle taxis are a widely favored mode of public transportation in Indonesia. There are several companies providing online motorcycle taxi services in Indonesia, with Gojek and Grab dominating the market. In this rapidly digitizing era, social media has become a platform for Indonesian citizens to express their evaluations and opinions. One common platform used by users to express their evaluations is the Google Play Store, where users can provide ratings and opinions on the applications they use, including users of Gojek and Grab applications.This research aims to understand and analyze the sentiments of the public towards the two dominant giants in the online motorcycle taxi market in Indonesia based on review data from the Google Play Store using the Naive Bayes algorithm. The data used consists of user reviews from May 14, 2023, to July 26, 2023, totaling 300 data points for each application. This data will undergo pre-processing to remove irrelevant elements. The Naive Bayes algorithm is used to classify the existing sentiments into two classes: positive and negative.The results of this research conclude that Gojek users give positive reviews at 49% and negative reviews at 51%, which include praises for the drivers and services provided by the company, complaints about the heaviness of the application, and some disruptions in the Gopay payment method. Meanwhile, Grab users give positive reviews at 67% and negative reviews at 33%, which include customer satisfaction with attractive promos, complaints about the heaviness of the application after the latest update, and the high cost of Grabexpress and Grabfood services.
