Abstract

Land registration activities through the Larasita Program in Medan City began in 2009 with the aim that access related to legal certainty of land rights, especially for small communities or economically weak people, receive the same treatment and status as those with more economical communities. The problem in this research is the legal arrangement of Larasita in relation to legal certainty and legal protection of land rights. Implementation of the Larasita program by the Medan City Land Office. Constraints faced by the Medan City Land Office in implementing the Larasita program and the solutions made to overcome these obstacles. This research uses an empirical juridical approach. A juridical approach is used to analyze various laws and regulations related to the existence of the Larasita Program (People's Service for Land Certification). Meanwhile, the empirical approach is used to analyze the law which is seen as the behavior of landowners that is patterned in people's lives, who always interact and relate in social aspects. This research uses data collection tools in the form of literature study / document study and interviews. To obtain primary data, interviews were conducted with 2 (two) Medan City Land Office employees (informants), and 2 (two) land owners (respondents). Analyzed using qualitative analysis techniques. The results of the discussion that Larasita legal arrangements are related to legal certainty and legal protection of land rights as regulated in Perkaban No. 18 of 2009 concerning Larasita was built and developed to realize the mandate of Article 33 paragraph (3) of the 1945 Constitution, Law number 5 of 1960 concerning Basic Agrarian Principles, Government Regulation Number 24 concerning Land Registration, Regulation of the Minister of Agrarian Affairs Number 3 Years 1997 concerning Implementing Provisions Government regulation number 24 of 1997 concerning land registration. Legal certainty and legal protection of land rights through the Larasita program has been realized by carrying out land registration and has been achieved by the issuance of a valid proof letter as a strong evidence tool in the form of a certificate as regulated in Government Regulation Number 24 of 1997.The implementation of land registration activities through the Larasita program at the Medan City Land Office has been carried out according to procedures based on the provisions of the prevailing laws and regulations. The existence of the Larasita program after the emergence of the Complete Systematic Land Registration Program (PTSL). The obstacles faced by the Medan City Land Office in implementing the Larasita program, namely internal factors consisting of the lack of budget for Larasita activities. Use of Larasita Vehicles for other activities. Difficulties in Making Schedule for Larasita visits, and Difficulties in Site Selection. External obstacles, among others, the internet network which is often disconnected. Infrastructure conditions that are difficult to reach. Lack of public knowledge. Lack of socialization. Internal solutions are carried out such as increasing the Larasita Budget. external solutions do outreach. Bring files and input data at the Medan City Land Office

Abstract

Pengabdian kepada masyarakat ini bertujuan untuk meningkatkan efektivitas keadministrasian pada Pimpinan Cabang Muhammadiyah (PCM) Pulo Brayan Sekitarnya melalui penerapan sistem informasi berbasis web. Saat ini proses administrasi masih dilakukan secara manual sehingga menimbulkan permasalahan seperti risiko kehilangan data, rendahnya efisiensi, dan keterbatasan akses. Transformasi digital dilakukan dengan tahapan persiapan, pengembangan infrastruktur, pelatihan keterampilan teknologi, implementasi sistem digital, monitoring, dan pengembangan berkelanjutan. Hasil dari program ini diharapkan mampu meningkatkan efisiensi pengelolaan data, efektivitas komunikasi, transparansi organisasi, serta keterampilan teknologi anggota PCM. Program ini juga menjadi langkah strategis dalam mewujudkan organisasi Muhammadiyah yang modern dan adaptif terhadap perkembangan teknologi.

Abstract

Digital data security has become a critical issue in the digital transformation era, particularly in the exchange of digital images that are vulnerable to interception and manipulation by unauthorized parties. This study aims to implement a layered data security method by combining Advanced Encryption Standard (AES) 256-bit cryptography and Least Significant Bit (LSB) steganography on PNG-format digital images. The approach used is encrypt-then-embed, where the secret message is first encrypted using AES-256 in CBC mode, then the ciphertext is embedded into the cover image pixels through LSB bit substitution. Testing was conducted on five test images with varying resolutions (256×256 to 1024×768 pixels) using Peak Signal-to-Noise Ratio (PSNR), Mean Squared Error (MSE), entropy, avalanche effect, and computation time metrics. The test results show an average PSNR of 70,58 dB and MSE of 0.11, indicating excellent visual quality of the stego images. Security analysis shows an average avalanche effect of 50.29%, approaching the ideal value of 50%, and stego image entropy approaching 7.0545 bits/pixel. The computation time for encryption and embedding processes ranges from 0,005847 to 0,006078 seconds. The combination of AES-256 and LSB has proven effective in providing layered security: AES-256 ensures data confidentiality, while LSB conceals the message existence within the image without significant visual degradation.

Abstract

Informasi produk Sikologi Kopi disampaikan melalui media sosial dan daftar menu, tetapi belum menyediakan visualisasi interaktif. Penelitian ini bertujuan mengembangkan aplikasi augmented reality (AR) berbasis Android untuk memvisualisasikan 20 produk melalui satu marker. Pengembangan menggunakan model Waterfall, dengan Unity sebagai platform implementasi dan Vuforia Engine untuk Marker-Based Tracking. Evaluasi meliputi 15 skenario black box, pengujian deteksi berdasarkan jarak, sudut, dan pencahayaan, serta pengujian pada Samsung Galaxy A05s. Seluruh skenario fungsi berstatus berhasil, termasuk navigasi katalog, visualisasi, rotasi objek, detail, favorit, dan berbagi. Marker terdeteksi pada jarak 10, 20, dan 30 cm, tetapi tidak pada 40 dan 50 cm. Pada jarak sekitar 30 cm, deteksi berhasil pada sudut 0°, 30°, dan 45°, tetapi gagal pada 60°. Deteksi berjalan baik pada pencahayaan terang dan normal serta tidak stabil pada kondisi redup. APK berhasil dipasang dan dijalankan pada perangkat uji. Aplikasi dapat menjadi media alternatif penyampaian informasi dan visualisasi produk Sikologi Kopi, dengan kinerja deteksi yang dipengaruhi kondisi pemindaian.

Abstract

Gim turn-based membutuhkan Non-Player Character (NPC) yang mampu memilih aksi berdasarkan perubahan kondisi permainan. Keputusan berbasis aturan sederhana dapat menghasilkan perilaku yang mudah diprediksi, sedangkan Monte Carlo Tree Search (MCTS) mampu menghasilkan keputusan yang lebih terarah dengan konsekuensi kebutuhan komputasi dari proses pencarian berulang. Penelitian ini merancang sistem smart decision menggunakan MCTS sebagai generator keputusan dan Multi-Layer Perceptron (MLP) sebagai model yang mengaproksimasi distribusi keputusan tersebut. Penelitian meliputi perancangan gim turn-based, implementasi MCTS terbatas, pembentukan dataset melalui simulasi MCTS melawan MCTS, preprocessing dan embedding, serta pelatihan MLP menggunakan KL divergence. Evaluasi pertama menggunakan 6.894 sampel dan evaluasi kedua menggunakan 15.288 sampel. Hasil menunjukkan bahwa MLP mampu mempelajari sebagian pola keputusan MCTS. Rata-rata akurasi meningkat dari 57,57% menjadi 62,84% pada tiga fase pembelajaran evaluasi pertama. Namun, keterbacaan sinyal keputusan masih rendah dengan mean interpretability sebesar -46,31 dan win ratio MLP sebesar 0,45. Nilai evaluasi berbobot mencapai 27,29 dan belum memenuhi kriteria 60. Pada evaluasi kedua, akurasi terbaik sebesar 54,82%, sehingga penambahan perspektif hero dan data belum meningkatkan generalisasi secara langsung. Meskipun demikian, MLP memiliki mekanisme inferensi yang lebih sederhana karena keputusan dihasilkan melalui satu proses propagasi maju.
