The IT governance audit aims to determine the level of importance (maturity level) of a company or government agency. IT governance audit is essential because if governance is not implemented correctly, the harmony between IT is beneficial to support business processes, and standard procedures will not be achieved. One of the agencies that require the implementation of good IT governance is Office X in Badung Regency. Office X in Badung Regency has a function in developing ICT infrastructure through application development, public service content, and ICT networks to improve public services. Conditions that occur in the field are frequent errors caused by internal and external parties that negatively impact the data management of Office X. The audit process begins with observations in the agency environment related to activity data and implementation, then mapping with business goals according to COBIT 5, followed by mapping business goals with IT Goals to obtain IT processes. The obtained IT processes are then selected to obtain critical IT processes according to the Executive Office. The audit results show that four IT processes need to be given recommendations for improvement, namely MEA 01, EDM 01, APO 07, DSS02.

Tingkat usability dapat mempengaruhi kemudahan penggunaan suatu aplikasi termasuk aplikasi mobile, sehingga penting untuk dilakukanya evaluasi. Aplikasi Simalu merupakan sebuah aplikasi lokal Bali yang bergerak dalam bidang kebersihan lingkungan. Simalu tergolong aplikasi baru karena dirilis pada awal bulan Januari tahun 2018 dan belum pernah dilakukan evaluasi usability sebelumnya. Evaluasi usability dilakukan untuk meningkatkan User Experience pengguna, sehingga aplikasi dapat diterima dan digunakan lebih mudah oleh pengguna. Metode yang digunakan untuk melakukan evaluasi yaitu usability testing dengan teknik Retrospective Think Aloud dan Performance Measurement. Hasil yang didapatkan adalah aplikasi Simalu memiliki kualitas yang belum dapat dikatakan efektif, efisien dan memenuhi kepuasan pengguna, sehingga perbaikan desain juga dilakukan agar aplikasi lebih baik lagi untuk memenuhi harapan pengguna. Kata kunci: Aplikasi Simalu, Evaluasi Usability, User Experience, Usability Testing, Retrospective Think Aloud, Performance Measurement.

DKI Jakarta merupakan daerah yang terkenal dengan bencana banjir pada musim hujan setiap tahun. Salah satu informasi mendasar yang dibutuhkan terkait bencana banjir adalah daerah tergenang banjir. Informasi genangan banjir digunakan untuk melakukan pemetaan dan perhitungan luas genangan, sehingga dapat diketahui daerah yang memiliki potensi banjir. Perhitungan informasi genangan banjir menjadi ide dasar dibentuknya penginderaan jauh pemrosesan data satelit Landsat 8 untuk deteksi genangan. Landsat 8 dimanfaatkan sebagai parameter utama dalam melakukan identifikasi genangan pada penelitian ini. Metode GSWIR (Green-Short Wave Infrared) diaplikasikan pada citra Landsat 8 menggunakan Band 3 (Green) dan Band 6 (SWIR). Metode GSWIR merupakan filter edge detection yang digunakan untuk memisahkan antara air dan non air. Hasil perhitungan metode GSWIR menunjukkan obyek permukaan mempunyai respon spektral dan luas yang bervariasi saat banjir (tergenang air) dan tidak banjir (tidak tergenang air). Metode GSWIR yang diaplikasikan membuktikan metode ini dapat digunakan untuk mendeteksi genangan dengan memisahkan antara air (genangan) dan non air (tidak tergenang air) dikarenakan Band Green memiliki kegunaan untuk memperbesar nilai reflektan dari air, dan badan air memiliki daya serap lebih kuat pada band SWIR. Kata kunci: DKI Jakarta, Genangan, Landsat 8 , GSWIR.

Pneumonia is an inflammatory lung disease that causes the second largest number of deaths in Indonesia after Dengue Hemorrhagic Fever (DHF). In 2021, there was an increase in cases of 7.8% compared to the previous year, and was exacerbated by the Covid-19 pandemic. Predictive methods were needed to predict and compare the ARIMA and MLP methods, where the results of the best methods were selected for long-term forecasting. The research data used was from January 2014 – December 2021, with a total of 96 data. In choosing the best method, the basic error calculations used were Mean Absolute Deviation, Mean Squared Error, and Mean Absolute Percentage Error. This study aims to build a predictive model for the next period of pneumonia under-five mortality. These results can be used for government policy-making related to mortality prevention for the next period. The results showed that the MLP method was superior to ARIMA. Testing 28 mortality rate data using the final test result showed that the best method was MLP, with a hidden layer value of 2.2, a learning rate of 0.3, and an error percentage of 1.27%. The prediction results of the overall mortality rate of pneumonia under five in 2022 was predicted to be 136 people.

Kecanduan terhadap smartphone dapat berakibat buruk bagi pelajar. Penelitian ini bertujuan memprediksi kecanduan smartphone di kalangan siswa-siswi SMA dengan menggunakan metode terbaik dari klasifikasi. Klasifikasi dilakukan untuk dapat mendukung pengambilan keputusan terkait masalah kecanduan smartphone. Algoritma C4.5, Naive Bayes (NB), dan K-Nearest Neighbor (KNN) merupakan metode klasifikasi machine learning yang digunakan pada penelitian ini. Metode ini merupakan metode klasifikasi machine learning yang termasuk dalam kategori top 10 dalam menyelesaikan kasus prediksi. Untuk dapat meningkatkan kinerja metode-metode machine learning tersebut, maka dilakukan seleksi atribut sebelum proses klasifikasi menggunakan Forward Selection, Backward Elimination, dan dengan pendekatan korelasi Linear Regression. Hasil penelitian menunjukkan bahwa metode terbaik untuk klasifikasi kecanduan smartphone adalah KNN dengan seleksi atribut menggunakan Linear Regression berdasarkan korelasi weight, yang mana atribut inputan yang berpengaruh secara signifikan terhadap output kecanduan smartphone (Y) adalah umur (X1), durasi penggunaan smartphone (X5), aktifitas (X6), dan kualitas tidur (X7) dengan model K = 44 dan numerical measure = Chebychev, menghasilkan accuracy = 79.03%, precision = 78.79%, recall = 81.25%, AUC = 0.828, dan running times = 1 detik. Output dari penelitian ini menunjukan prediksi dengan menggunakan metode terbaik yaitu presentase tingkat kecanduan siswa dengan tidak kecanduan serta presentase kecanduan smartphone dengan variabel lainnya.

Website is a medium that cannot be separated from technological developments, websites are needed because of their practical and easy use, especially a landing page website that is used by business and non-profit people to convey information. The website is developed using a custom-built architecture so that the development and maintenance process runs well. The world is developing faster and faster so that the old website development architecture over time is increasingly difficult to adapt, so there is a new website development architecture, one of which is Jamstack, the Jamstack architecture is said to have advantages over the old architectures that are widely used until now, one of which is LAMP Stack, to ensure the correctness of these arguments, a detailed analysis is needed so as to get results that match the facts.
