This study examines the implementation of information system at RSUD Palembang BARI with the aim of enhancing information system security. In this context, a security audit is conducted using the COBIT 2019 framework. The COBIT 2019 domains and processes utilizing include EDM03, APO12, APO13, APO14, and DSS05. The research involves the identification and evaluation of information security risks, determination of necessary security controls, and ensuring compliance with the information security standards established by COBIT 2019. The findings indicate that the level of information system security at RSUD Palembang BARI is at level 3 (Defined), with a gap analysis difference of 1 level below the expected target. Based on the above results, efforts to improve and enhance the information system security at RSUD Palembang BARI are still needed. The use of information system security techniques such as vulnerability scanning, penetration testing, WAF, IDS and IPS, and data encryption, as well as improving security in terms of server physical aspects such as installing CCTV and restricting user access with access cards or fingerprints, can be implemented to ensure compliance with relevant information security standards. Consideration for obtaining security certifications, like ISO 27001, should also be taken. Additionally, the quality of human resources in terms of policy-making and the ability of employees to address threats and attacks on information system security should be improved through training and strengthening coordination among employees.

The process of ordering food and beverage menus at the Meatzilla restaurant still uses paper and stationery. Constraints that are often encountered are when restaurant visitors are crowded, but waiters are limited, often mistaken of orders and loss and order of paper orders and various other obstacles. This can cause feelings of disappointment and negative impressions which will certainly result in reduced customer satisfaction. This study aims to produce mobile device software that can support the running of food and beverage ordering systems at Meatzilla Restaurant self-service so that orders arrive quickly and right desires. This system is made using XML and java programming language with android studio tools version 3.5.3. Research in the form of case studies, software design methods using extreme programming models and system modeling tools using Unified Modeling Language (UML). This system is connected to the internet network where the admin, cashier, kitchen and customers are integrated with a restful web service. The final result of this study is a food and beverage ordering system consisting of 4 (four) parts, namely customer and admin software that is accessed by using a smartphone and the cashier and kitchen which is accessed by a PC / laptop. this system is very helpful in facilitating the management of customer orders.

The Ministry of XYZ's Data and Information Center is a supporting element that is under and responsible to the Minister through the Secretary General with the task of preparing governance and information technology management infrastructure, developing, and implementing information system innovations and data management and information presentation. Information technology management is carried out to facilitate the management, monitoring and evaluation of every business process and information technology to achieve organizational goals. COBIT 2019 is used to assist organizations in managing and optimizing existing information technology by examining the 10 existing design factors and then analyzing the level of capability in each of the top three domains. The result of this research is the capability level of the domains BAI02, BAI03, and BAI07, which is then made recommendations from the domains that have gaps.

Today, the millennial generation is increasingly inseparable from gadgets. Most of their time is spent interacting using these gadgets. So that even during lectures, they can be sure that they will continue to interact using these gadgets. When this millennial generation is undergoing lectures in the classroom, usually attendance will be circulated using a paper attendance list and students must sign the paper as proof of class attendance. This often creates problems when there are students who leave their presence through classmates. The solution to this problem is to develop a mobile-based online presence system. The urgent need for an online presence system causes the system to be developed quickly. The suitable method for rapid system development is Rapid Application Development (RAD). This QRCode-based online attendance system has succeeded in overcoming the problem of entrusting presence through classmates.

Digitalisasi dan otomasi dalam pelayanan mahasiswa di Perguruan Tinggi dapat menghasilkan big data. Amanat pemerintah dalam Peraturan Mentri Riset Teknologi dan Pendidikan Tinggi agar besaran Uang Kuliah Tunggal (UKT) di Perguruan Tinggi Negeri dibagi ke dalam 5 kelompok berdasarkan tingkatan kondisi sosial ekonomi orang tua. Dalam proses menetapkan UKT begitu banyak indikator sosial ekonomi orang tua yang harus dijadikan acuan sehingga menyulitkan dalam mengidentifiksi dan mencari formula yang tepat. Untuk mengelompokkan data mahasiswa ini dilakukan dengan teknik data mining menggunakan metode K-Means Clustering. Metode ini mengelompokkan besaran UKT mahasiswa berdasarkan pola atau kemiripan data sosial ekonomi orang tua. Data yang digunakan dalam penelitian ini adalah data calon mahasiswa baru Unversitas Negeri Padang. Pengelompokan ini bertujuan untuk membantu menetapkan besaran UKT calon mahasiswa baru pada Perguruan Tinggi Negeri. Hasil dari penelitian diperoleh 5 kelompok besaran UKT, terdiri dari UKT kategori 1 Rp. 500.000, UKT kategori 2 Rp. 1.000.000, UKT kategori 3 Rp. 2.000.000, UKT kategori 4 Rp. 3.000.000 dan UKT kategori 5 Rp. 4.000.000.

Di kota besar seperti Surabaya yang mempunyai kepadatan lalu lintas yang cukup tinggi, merupakan permasalahan yang rumit untuk diselesaikan. Peningkatan jumlah pengguna jalan menyebabkan kepadatan yang semakin tinggi. Pada sistem lalu lintas yang bersifat dinamis, pencarian jalur berdasarkan jarak terpendek harus memperhitungkan kondisi kepadatan lalu lintas pada suatu waktu. Pengguna jalan lebih efektif dan efisien dalam menentukan jalur yang dilewati, apabila mempertimbangkan faktor kepadatan. Pada penelitian ini dilakukan pengembangan pencarian jalur menggunakan algoritma koloni semut (ant colony algorithm). Algoritma koloni semut diaplikasikan pada peta untuk menemukan jalur optimal berdasarkan jarak tempuh dengan mempertimbangkan kondisi kepadatan lalu lintas pada suatu waktu. Sistem yang dibangun dapat menjadi alat bantu bagi pengguna jalan untuk memilih jalan yang dilakukan berdasarkan informasi kondisi kepadatan, arah jalan dan serta jalur yang dapat dilalui oleh jenis kendaraan tertentu. Algoritma koloni semut dapat melakukan pencarian jalur dengan baik dengan sesuai dengan bobot jumlah lajur jalan dan jenis kendaraan.

As beginners, many first-year students have difficulty understanding object-oriented programming material. To help students learn algorithmic and object-oriented programming material researchers have developed visual programming (PV). Visual programming is a tool to facilitate learning programming. The concept of learning to use PV visualizes the work processes of algorithms and programming. This research aims to compare three dynamic PV tools for object-oriented learning programming that are the most studied. To determine the PV to be compared, a survey was conducted in an online journal database, such as IEEE explore, ACM, and several well-known online publishers. From the survey results, three dynamic PVs were chosen, most widely discussed, namely Jeliot 3, Ville and Jive. All three tools are installed and studied. Comparison results show that each dynamic PV has advantages on certain characteristics. The instructor can choose visual programming by considering the advantages of each PV.
