Abstract

Dengan berkembang pesatnya teknologi, memiliki televisi sangatlah mudah, namun perawatannya yang sulit. Akan sangat membantu jika memiliki pengetahuan tentang elektronika. Oleh karena itu dikembangkan sistem pakar untuk mendiagnosa kerusakan televisi. Sistem pakar adalah sistem berbasis komputer yang menggunakan pengetahuan, fakta, dan teknik penalaran dalam memecahkan masalah yang biasanya hanya dapat dipecahkan oleh seorang pakar dalam bidangnya. Sistem pakar mencoba mencari solusi sebagaimana yang dilakukan seorang pakar. Sistem pakar juga dapat memberikan penjelasan terhadap langkah yang diambil dan memberikan saran atau kesimpulan yang ditemukannya. Mendeteksi kerusakan sejak dini dapat mencegah kerusakan lebih parah dan menangani kerusakan tersebut dengan benar. Sistem pakar dapat membantu untuk mendiagnosa kerusakan dan memberikan solusi atas kerusakan tersebut. Pembangunan sistem ini bertujuan untuk membantu pengguna mengatasi kerusakan televisi. Sistem ini dibangun menggunakan metode forward chaining. Forward chaining digunakan untuk menguji faktor-faktor yang dimasukkan dengan aturan yang disimpan dalam sistem hingga dapat diambil kesimpulan.  Sistem pakar ini memiliki fungsi khusus bagi pakar untuk menambah, mengubah dan menghapus pengetahuan atau aturan tanpa harus membuka database. Sistem pakar ini dibuat dengan menggunakan PHP dan MySQL sebagai basis datanya. Due to advancement in technology getting a television is easy, but maintaining it is very difficult. It will be helpful if we have some knowledge on electronics. Here we develop an expert system for television troubleshooting. Expert system is computer-based system that uses knowledge, facts, and reasoning techniques in solving problems that typically can only be solved by an expert in their field. Expert system try to find a solution as did an expert. Expert system can also provide an explanation of the steps taken and give suggestions or conclusions discovery. Detecting damage at early stage can enable to overcome and treat them appropriately. This expert system can help a great deal in identifying those damage and describing methods of treatment to be carried out. Development of an expert system aimed at helping users to resolve the problem or damage to television. This system is built using forward chaining method. Forward chaining is used to examine the factors that put the rules stored in the system until it is concluded. This expert system has features for the expert to add, modify, and delete knowledge or rules without open the database. In order to built this expert system using PHP and MySQL for the database.

Abstract

Penelitian ini merancang jaringan 4G menggunakan frekuensi 700 Mhz dengan bandwidth 20 Mhz di kawasan Kroya, Cilacap seluas 31,636 km2. Model propagasi yang digunakan adalah Okumura-Hatta. Simulasi prediksi coverage menggunakan Software Atoll 3,4 yang menggunakan frekuensi 700 Mhz. didapatkan jumlah Base Tranceiver Station (BTS) sebanyak 25. Berdasarkan jumlah Base Tranceiver Station (BTS) tersebut, maka dilanjutkan dengan mensimulasikan dengan parameter-parameter penelitian yang telah ditentukan. Rata-rata tingkat sinyal (Coverage by Signal) pada SU-MIMO dan MU-MIMO didapatkan nilai sebesar -91,35 dBm dan -91,62 dBm. Rata-rata tingkat sinyal dan rata-rata kekuatan sinyal efektif pada Single-User Multiple Input Multiple Output (SU-MIMO) -123,8 dBm sedangkan pada Multiple Input Multiple Output (MU-MIMO) sebesar -120,71 dBm, rata-rata rasio C/(I+N) pada SU-MIMO sebesar 3,79 dB sedangkan pada MU-MIMO 3,28 dB tidak menunjukkan perbedaan yang signifikan. SU-MIMO mendukung throughput tinggi untuk satu pengguna yaitu sebesar 15,082 Kbps, sedangkan MU-MIMO menunjukkan stabilitas yang lebih baik dengan throughput yang lebih konsisten yaitu sebesar 13,638 Kbps.

Abstract

Technological advances in this era can support public services to serve the public more quickly and responsively. One of the electronic public services used by citizens in Indonesia is the application for a passport. After launching to the public in early 2022, the mobile app M-Paspor is still experiencing some obstacles. This study aims to get recommendations for government consideration based on public experience as users of the M-Paspor application. This study integrates the e-Govqual model initiated by Papadomichelaki & Mentzas and End User Computing Satisfaction by Doll & Tork Zadeh. Six dimensions are used: ease of use, trust, functionality of the interaction environment, reliability, content and appearance of information, and citizen support. With the questionnaire distributed through social media, we analyzed data from 111 respondents. We conducted an analysis using SmartPLS to validate the survey. The result implied that Citizen Support, Functionality of the Interaction Environment, and Reliability significantly influence End User Computing Satisfaction of M-Paspor users

Abstract

This study aims to obtain empirical evidence regarding the influence of audit findings and audit follow-up on corruption levels in provincial governments in Indonesia. Audit findings are analyzed into two categories: internal control weaknesses and non-compliance with laws and regulations. The method applied in this study is a quantitative, purposive sampling approach across 34 provinces in Indonesia during the 2021–2023 period, yielding 102 observations. The secondary data sources were obtained from ICW reports, IHPS BPK, and BPS publications. The data analysis used in this study was multiple regression with a random effects model. The results show that internal control weaknesses has a significant positive effect on corruption levels, and audit follow-up has a significant negative effect on corruption levels. Meanwhile, non-compliance with laws and regulations does not have a significant effect on corruption levels. These findings indicate that weaknesses in internal control systems can create opportunities for corruption, and effective follow-up on audit results can suppress such practices. In contrast, non-compliance with laws and regulations makes it difficult to verify corruption due to information asymmetry.
