Abstract

Motor vehicle tax payments represent a substantial portion of regional income. However, recurrent delays in motorbike tax payments, notably in the Kandang Limun sub-district of Bengkulu City, pose a significant threat to regional development. This research aims to address these delays by predicting and implementing effective strategies. Using the RapidMiner application and the Artificial Neural Network (ANN) method, a delay rate of 36.14% was predicted. The study incorporates interviews to propose several strategies, including enhancing websites, improving offline and online services, implementing Drivethru services, and using SMS Blast notifications to combat delays. To evaluate the feasibility of these strategies, the research employs the Strategy Alignment Maturity Model (SAMM). The assessment at BPKD reveals a maturity level of 4, signifying an ability to improve and manage processes effectively.The maturity assessment suggests that the proposed strategies for overcoming delays are well-aligned with BPKD's capabilities. They have demonstrated a robust alignment between IT and business strategies, leveraging IT to enhance performance, and conducting thorough business and IT evaluations.In addition to the maturity assessment, the research offers suggestions and evaluation strategies. These encompass the adoption of biometrics for authentication, implementation of chatbots, Samsat self-service kiosks, real-time vehicle monitoring, and the introduction of automatic tax programs.

Abstract

Roguelike is a genre of role-playing video game in which the player explores dungeons through procedurally generated levels. If they lose, the player loses progress, and the character starts over again. Procedural Content Generation (PCG) is a computer program that can create game content automatically, randomly, and uniquely, either by itself or with human assistance. In this study, the 3D roguelike game was designed with players playing a character to explore dungeons. Players will enter at one point, explore the surrounding environment, defeat the enemies encountered, avoid traps, collect treasure, and finally exit at another point. Each time the player starts a new game session, the game will generate a dungeon with a mission structure that changes randomly to create a variety of gameplay. This mission generation is implemented using the Graph Grammar method. The game is built using the Unity game engine and is intended to run on Android devices. Based on the black box test results, all the game's features are running well according to their functions. The built games will be evaluated using the GUESS-18 to determine the level of player satisfaction. Based on the evaluation results, the game is included in the "GOOD" category, with an overall score of 49.07 out of 63 maximum scores. The game that has been built is superior in the aspect of personal gratification, while it is weak in the aspect of social connectivity.

Abstract

Forest fires are still one of the most common problems in Indonesia. In fact, many of these forest fires origin from human activities, namely fires that are intentionally raised for a purpose such as widening the land to prepare for the planting season in the Nusa Tenggara Island. Forest fire events can be identified by observing hotspot data which are monitored through remote sensing satellites. Hotspot is an area that has a relatively higher surface temperature than the surrounding area based on certain temperature thresholds monitored by remote sensing satellites. The objective of this research is to cluster hotspots in the Nusa Tenggara and Bali Islands from year 2013 to 2018 using the K-Means Clustering Method with 28,519 hot spot data. By knowing this result, the ministry can use this data for patrol priority management. This research successfully clustered three types of hotspot classes based on the risk of fire with details as follow; High Risk Class contains 12,212 data with ranges of mean values of confidence in the range of 49.3–100%, brightness in the range of 305.1–421.3o K and FRP in the range of 2.5–714.3; Medium Risk contains 12,250 data mean values of confidence with a range of 20.3–74.3%, brightness in the range of 301.06–341.86o K and FRP in the range of 3.6–141.4; and Low Risk contains 4,057 data with a range of mean values of confidence in the range of 0–39.8%, brightness in the range of 300–365.86oK and FRP in the range of 3.5–275.6.

Abstract

In 2007, Bengkulu city, Indonesia and its surrounding areas experienced a significant earthquake with a magnitude of 8.6 Mw, resulting in extensive damage. Between 2014 and 2022, Bengkulu Province encountered a total of 3469 earthquakes, signifying a heightened frequency of seismic activity in the region. This escalated seismic activity in Bengkulu elicits concerns regarding potential ground surface deformation. To address this, the study utilized DInSAR (Differential Interferometry SAR) technology, employing a blend of satellite images to quantify land surface deformation. Notably, the research made use of three pairs of satellite images for analysis. One pair of ALOS-PALSAR images dated between January 29 and September 16, 2007, was employed to investigate ground surface deformation following the September 12, 2007 earthquake. Additionally, observations were made using two pairs of Sentinel-1 satellite images covering periods from November 3 to 27, 2014, and from June 30 to July 24, 2022, to monitor land surface deformation resulting from earthquakes on November 10, 2014 and July 20, 2022. The study findings depicted uplift deformation reaching 53.4 mm and the highest subsidence measuring -12.8 mm in the ALOS-PALSAR image pair. In the Sentinel-1 image pair between November 3 and 27, 2014, the most notable observed uplift amounted to 38.9 mm, while the greatest subsidence was recorded at -34.8 mm. Lastly, the image pair dated between June 30 and July 24, 2022, exclusively exhibited uplift, with values peaking at 45.2 mm.

Abstract

Transkrip akademik merupakan dokumen yang sangat rahasia di lembaga pendidikan. Oleh karena itu, transkrip akademik harus memenuhi aspek keamanan informasi, yaitu autentikasi, keaslian pesan (integritas data), dan non-repudiasi. Banyak kasus telah dilaporkan terkait pemalsuan dan penyalahgunaan transkrip akademik. Hal ini disebabkan karena tidak adanya perlindungan terhadap integritas dan autentikasi transkrip akademik. Prosedur validasi diperlukan untuk menjamin integritas dan keaslian transkrip akademik. Untuk memberikan perlindungan terhadap integritas dan otentikasi, prosedur tanda tangan digital diperlukan pada transkrip akademik. Tanda tangan digital adalah skema yang terdiri dari dua komponen, yaitu penandatanganan dan verifikasi. Skema ini digunakan untuk menjamin integritas informasi dalam dokumen digital. Penelitian ini mengusulkan prosedur validasi transkrip akademik yang sangat otentik berdasarkan tanda tangan digital menggunakan algoritma Rivest Shamir Adleman (RSA) dan BLAKE3. Skema yang diusulkan memanfaatkan kombinasi algoritma RSA dan fungsi hash BLAKE3 dalam implementasi algoritma tanda tangan digital. Hasil eksperimen menunjukkan bahwa sistem dapat menjamin validitas dokumen transkrip digital dalam format PDF. Kecepatan proses penandatanganan rata-rata pada server localhost A adalah 55,0511 milidetik dan kecepatan verifikasi adalah 19,2658 milidetik. Pada server localhost B, kecepatan rata-rata proses penandatanganan adalah 41,8563 milidetik dan kecepatan verifikasi adalah 11,9715 milidetik.

Abstract

The Bengkulu City Public Housing and Settlement Agency is a government agency tasked with assisting the mayor in administering government affairs related to public housing, settlement areas, and land matters under regional jurisdiction. In addition, the Department of Public Housing and Settlement Areas also has an obligation to serve the community and always strives to provide the best service information to the community, especially in Bengkulu City. This is particularly true in terms of housing data collection processed by the Department of Public Housing and Settlement Areas in Bengkulu City. The housing data collection system used for office purposes in terms of monthly or annual reports and archives at the Public Housing and Settlement Agency is not yet computerized. However, to date, these main activities are still carried out manually. The storage of this data is also still piled up in cabinets, which requires a long time to create reports and search for the data itself. This need can be facilitated by the existence of computational products and algorithms in the Informatics program that synergize with Geophysics in addressing data collection and landscape analysis issues related to housing and settlements. The implementation of this integrated system improves the management process of plot pattern data, basic infrastructure, uninhabitable house, and developer.  This research showed that the total calculation, the average System Usability Testing score obtained was 62.5, which falls under the good category. This indicates that the developed system meets usability standards and is well accepted by its users.
