Abstract

Lake Toba has been designated as one of Indonesia's Super Priority Tourism Destinations (DPSP). The Kaldera Toba Nomadic Escape is a tourist attraction within the Lake Toba DPSP area, managed by the Lake Toba Authority (BPODT). Visitors to the Toba Caldera tourist area often face challenges, particularly those from outside the region who cannot book tickets online. Additionally, ticket sales data at Caldera is still managed manually using traditional bookkeeping methods, which prevents immediate compilation and accurate reporting of sold tickets. There are two categories of ticket bookings available at the Toba Caldera: entry tickets for general tourist access and event tickets, which are only available when events are organized at the Kaldera Toba Nomadic Escape. To facilitate easier management of ticket bookings at the Kaldera Toba Nomadic Escape, a web-based system has been developed, enabling visitors to book tickets online. This system includes a dashboard that allows for real-time transaction recapitulation. The system development follows the Waterfall model, which consists of several stages: Communication, Planning, Modeling, Construction, and Deployment. In developing the ticket sales dashboard, a comparative analysis of several previous studies was also conducted to enhance the visual details and functionality of the ticket sales dashboard. As a result of this research, a web-based ticket booking system and sales dashboard were developed. The ticket booking system allows visitors to easily purchase tickets, while the sales dashboard enables the Kaldera Toba Nomadic Escape management to monitor important statistics, such as the number of visitors, ticket sales, and the availability of tickets in real-time.

Abstract

The implementation of e-Learning at ITB STIKOM Bali represents a significant support for online learning. The Learning Management System (LMS) called e-Learning ITB STIKOM Bali, based on Moodle LMS, is used to conduct lectures online. e-Learning is integrated with SINAK (Academic Information System), SID (Lecturer Information System), and SION (Online Information System) for both students and lecturers, including course registration and enrollment of students and lecturers. This system is used for both fully online lectures (Asynchronous Learning) and blended learning lectures in all study programs. However, proper maintenance and management of this system are necessary. Therefore, evaluation and analysis in IT governance related to the used LMS are required. In order to measure the maturity level of the e-Learning LMS implementation, measurement based on mapping and measuring the level of capability or gaps is needed. This measurement is conducted using the Process Assessment Model (PAM) within the COBIT 5 framework. Measurement activities will be based on several domains within COBIT 5, with process mapping based on business goals and institutional objectives. Based on the process mapping using PAM, domains strongly related to institutional IT goals focusing on customers and internal aspects are identified: MEA01 (Monitor and Evaluate Performance and Conformance), DSS 03 (Manage Security Services), APO13 (Manage Security), EDM 03 (Ensure Risk Optimization), BAI 07 (Manage Change Acceptance and Transitioning).

Abstract

Microalgae are unicellular microscopic organisms that live in various water. Microalgae such as Spirulina platensis and Chlorella vulgaris are grown due to their potential as bioenergy source. During cultivation, typically, hemocytometers are used to manually count the cells and that is time-consuming and prone to human error. This research aims to develop microalgae detection model based on microscopic images and Convolutional Neural Network using YOLOv8 architecture. The methodology includes sample preparation (dilution and optical density measurement), best density determination, image acquisition, annotation, creation of datasets, YOLOv8 model training, and model performance evaluation. Best density determines good microscopic images. Image acquisition was done using binocular microscope and acquired 560 images which were then annotated. The YOLOv8n, YOLOv8s, and YOLOv8m models were trained using default hyperparameters on Google Collaboratory to determine the augmentation effect on model accuracy. Model performance evaluation was done on selected YOLOv8 models. The results showed the augmentation (crop, brightness, blur) get the highest mAP train and test on YOLOv8m model, which are 0.945 and 0.913. The YOLOv8m model was retrained with various hyperparameters and it was found that the best configuration was SGD optimizer, epoch 50, and learning rate 0.01 with mAP train and test are 0.934 and 0.925. However, 29 epochs yielding a better model with accuracy of 0.8535, minimising overfitting and resource wastage. This research can facilitate the more efficient and automatic counting for microalgae-related research and industry.
