"If you’re an iOS app developer, chances are you’ll be using table views in your development projects. Table views are the bread and butter of iOS apps. With them, you can create everything from the simplest of lists to fully tricked-out user interfaces. Table views are also one of the most complex components found in UIKit. While using them for boring standard user interfaces is quite simple, customizing them can become really challenging.Pro iOS Table Views takes a task-oriented focus to assist you when implementing customized table views. Although it delves deeply into the Table View API, you can always decide in which level of detail you want to dive in. It’s aimed to be a great reference and customization cookbook at the same time, useful for beginners as well as intermediate developers. Fitur, covers the entire Table View API in depth, covers customization and performance topics in depth, and task-oriented reference with multiple levels of detail."

"Metodologi inversi simultan telah dilakukan untuk mendelineasi dan menkarakterisasi reservoir utama pada lapangan “R”, Cekungan Kutei, Indonesia, hasil dari inversi simultan adalah attribute karakter batuan (Vsh,Porositas dan Saturasi air). Namun, hasil yang kita dapatkan pada target sekunder banyak ambigu dan tidak bisa digunakan oleh Interpreter untuk memperbarui moldel bumi. Oleh karena itu, Proses inversi simultan Akan kembali dilakukan menggunakan kontrol sumur yang tersedia untuk reservoir tersebut tetapi dengan wavelet yang berbeda dengan inversi yang pretama. Wavelet yang diekstrak dikontrol oleh jendela waktu antara tiap horizon. Inversi simultan kedua dilakukan dengan menggunakan wavelet yang difokuskan pada Horizon atas dan bawah dari reservoir sekunder. Tujuan dari proyek ini adalah untuk membangun volum karakteristik batuan (Vsh, Porositas dan Saturasi) untuk reservoir sekunder yang dapat digunakan oleh interpreter untuk memperbarui model statis bumi saat ini . Sifat batuan akan diperkirakan dari produk inversi simultan (P-Impedance, S-Impedansi dan rasio VpVs).

Simultaneous inversion methodology has been done to delineate and characterize the primary reservoir at R field, Kutei Basin, Indonesia, resulting rock properties attributes (Vsh, Porosity and Saturation) derived from seismic inversion result. However, the result on the secondary target was ambiguous and can’t be used by interpreter to update the earth model. This study focuses on characterizing the reservoir at the secondary target. Therefore, simultaneous inversion process will be re-run using wells control that was available for this particular reservoir but with a different wavelet that was extracted. Wavelets that are extracted are controlled by the time window between the horizons. The second simultaneous done was using a wavelet that was focused on the top and bottom horizon of the secondary reservoir.

The objectives of this project are to build rock properties volume ( Vsh, Porosity and Saturation) for secondary reservoirs only that can be used by interpreter to update current static earth model. Those rock properties volumes will be estimated from simultaneous inversion products (P-Impedance, S-Impedance and VpVs ratio)."

"Secara global, perangkat Apple terutama iOS memiliki 24.7% smartphone market share. Hal ini reputasi perangkat iOS menjadi perangkat paling aman dibandingkan Android. Hal ini seiring dengan barang bukti yang dominan dalam kasus forensik digital. Tantangan yang dihadapi oleh pemeriksa forensik pada perangkat iOS adalah bagaimana mendapatkan akses kedalam perangkat tersebut. Perangkat iOS yang terkunci memiliki dua kondisi yang berbeda, yaitu After First Unlock (AFU) dan Before First Unlock (BFU). Oleh karena itu diperlukan suatu penelitian untuk mengetahui informasi apa saja yang dapat diperoleh pada perangkat iOS yang terkunci. Penelitian ini bertujuan untuk melakukan akusisi dan analisa terhadap kondisi perangkat terkunci tersebut. Perangkat yang digunakan pada penelitian ini menggunakan iPhone 11 dengan iOS versi 17.4.1 dan menggunakan tools Cellebrite UFED Premium untuk melakukan akuisisi. Hasil akuisisi dari perangkat tersebut didapatkan informasi bahwa pada kondisi BFU jumlah data yang dapat dipulihkan sekitar 61.31% dan pada kondisi AFU sekitar 97.45% dibandingkan dengan akuisisi Full File System (FFS). Pemeriksaan nilai hash menunjukkan integritas data yang sangat baik, yaitu pada BFU 98.57% dan AFU 89.84% memiliki nilai hash yang sama terhadap akuisisi FFS. Hasil dari tahapan pengujian dan analisis dibuatkan alur instruksi kerja yang diharapkan menjadi referensi.

Globally, Apple devices, particularly iOS with a 24.7% smartphone market share, are increasingly encountered as digital forensic evidence. The rank is probably affected by iOS reputation that is the most secure mobile device. This aligns with the dominance of such devices as evidence. A key challenge for forensic examiners with iOS devices is gaining access to them. Locked iOS devices come in two distinct states: After First Unlock (AFU) and Before First Unlock (BFU). Therefore, research is needed to determine the information recoverable from locked iOS devices. This study aims to acquire and analyze data from such locked devices in both AFU and BFU states. An iPhone 11 running iOS 17.4.1 was used for the study, and Cellebrite UFED Premium was employed for data acquisition. The data acquisition process yielded 61.31% files from the BFU device and 97.45% files from the AFU device compared to Full File System (FFS) acquisition result. Hash value verification indicated excellent data integrity, with 98.57% and 89.84% of files in BFU and AFU devices, respectively, matching the hash values obtained from the FFS acquisition. A work instruction flow was made from the examination and analysis results that is expected to be a reference."

"Media dua dimensi merupakan media konvensional yang marak digunakan secara umum. Namun begitu, media dua dimensi yang dalam hal ini berbentuk fisik, secara pelan mulai ditinggalkan dengan masifnya digitalisasi. Hal tersebut disayangkan karena banyak sumber ilmu dan informasi yang bisa saja hanya berada pada media dua dimensi. Untuk bisa membuat penggunaan media dua dimensi menjadi lebih menarik, teknologi augmented reality bisa menjadi jawaban. Dalam hal ini dikembangkan aplikasi iOS bernama readAR dengan penerapan teknologi visual inertial odometry menggunakan ARKit yang dapat melakukan pendeteksian gambar dan analisis visual dalam melakukan penempatan objek untuk bisa menghadirkan interaksi yang diinginkan pada teknologi augmented reality. Pada readAR dapat dihadirkan interaksi dalam bentuk objek tiga dimensi menggunakan SceneKit serta video menggunakan SpriteKit. Berdasarkan hasil analisis perhitungan, didapatkan nilai interaksi pada media koran untuk objek tiga dimensi memakan nilai senilai 1.45 lebih lama  dibandingkan video pada media koran dan 2.7 kali pada media majalah. Dari pengujian performa terhadap CPU, didapatkan kesimpulan interaksi video menggunakan CPU lebih besar dengan selisih 3% pada media koran dan 5.1% pada media majalah. Hal yang sama juga terjadi pada pengujian memory, dengan selisih 23.01 MB untuk media koran dan 21.17 MB untuk media majalah.

Two-dimensional media is a conventional medium that is widely used in general. However, two-dimensional media, which in this case is in physical form, is slowly being abandoned due to massive digitization. This is unfortunate because there are many sources of knowledge and information that can only exist in two-dimensional media. To make the use of two-dimensional media more interesting, augmented reality technology can be the answer. In this case, an iOS application called readAR was developed with the application of visual inertial odometry technology using ARKit, which can perform image detection and visual analysis to place objects and provide the desired interaction with augmented reality technology. In readAR, interactions can be presented in the form of three-dimensional objects using SceneKit and videos using SpriteKit. Based on the results of the calculation analysis, it was found that the interaction value for three-dimensional objects on newspaper media takes 1.45 times longer than videos on newspaper media and 2.7 times longer for magazine media. Testing the performance of the CPU showed that video interaction uses a larger CPU, with a difference of 3% for newspapers and 5.1% for magazines. The same trend was observed in the memory test, with a difference of 23.01 MB for newspapers and 21.17 MB for magazines."
