VANET (Vehicular Ad-Hoc Network) adalah bentuk khusus dari MANET (Mobile Ad-Hoc Network). VANET (Vehicular Ad-Hoc Network) adalah jaringan yang terdiri dari kumpulan node mobile nirkabel yang berkomunikasi satu sama lain tanpa infrastruktur yang tetap. Pergerakan MN (Mobile Node) pada VANET sangat tinggi dan menyebabkan IP Address pada MN sering berubah. Berdasarkan kondisi jaringan yang berubah, koneksi yang terjadi antara MN menjadi terganggu dan terputus selama beberapa detik. Selain itu, menyebabkan delay yang besar dan throughput yang lebih kecil dengan paket loss tinggi jika di suatu daerah jumlah MN meningkat secara signifikan. Dalam simulasi ini diukur kinerja antara jaringan Mobile IPv6 (MIPv6) dan Hierarchical Mobile IPv6 (HMIPv6) menggunakan agen transport UDP dengan beberapa ukuran paket data CBR. Berdasarkan parameter utama dalam menentukan kualitas jaringan, akan dibandingkan dan diperoleh nilai dari handover latensi, dengan mengukur packet loss, throughput, dan delay. Berdasarkan hasil studi literatur, dapat disimpulkan bahwa kinerja jaringan HMIPv6 lebih baik daripada MIPv6 karena HMIPv6 memiliki paket loss dan delay yang lebih kecil dan throughput yang lebih besar dibandingkan dengan MIPv6.

Phishing and identity theft are common threats of online shopping. Phishing is an attempt to steal personal data from legitimate user. In this paper we propose a secure e-payment method using a credit card based on visual cryptography. This method adopts the existing 3D-Secure technology. Visual cryptography is applied in: user-merchant authentication, user-card provider authentication, user-card issuer authorization. It is applied to captcha image generated by merchant during registration using (2, 2) scheme with 2-subpixel expansion, to a text file containing credit card information sent by merchant to the card provider using (2, 2) scheme with pixel replacement, and to quick response code containing one-time-password that is used to authorize the payment transaction using (2, 2) scheme with 4-subpixel expansion. The test results show that out of 100 trials, all of them give 100% true positive. This indicates that the method is able to prevent phishing and identity theft, in sense of authentication, authorization, confidentiality, and integrity are gained. Phishing can be prevented because only legitimate participant who has an image share. Identity theft can be prevented because credit card details are not stored in the merchant’s database. Authorization is more guaranteed because only authenticated user can authorize the payments.

The high number of deaths due to traffic accidents is still a problem for every country where Indonesia ranks third in Asia with 38,279 deaths according to the 2015 Global Status Report on Road Safety. Blackspots scattered in Indonesia has a role in contributing to the death rate, however not all blackspots are equipped with warning signs. Based on these problems then developed a prototype in the form of a device for detecting and website as the central information system of blackspots based Internet of Things. The prototype is designed using an Arduino Uno Rev 3 microcontroller equipped with a GPS module to measure vehicle speed and distance from the setpoint before arriving on blackspots, a GSM module to download blackspots data and upload speed and distance data to the database, and LED components, speakers/buzzer, OLED display to provide notification every time crossing the setpoint of blackspots. The usability testing performance measurement method is used to measure the performance of the device prototype and the black box testing method is used to validate each function of the website system. The results of this research obtained the success rate of the prototype device was 60% with the highest error rate of 19.09% at the 1500m setpoint for speed and 57.98% at 10m setpoint for the distance.

Indonesia merupakan negara kepulauan yang memiliki banyak wilayah yang sulit dijangkau, terutama di daerah perbatasan atau rural. Selain itu ketidaksetaraan distribusi penduduk dan ekonomi membuat pembangunan infrastruktur Teknologi Infomasi dan Komunikasi (TIK) secara keseluruhan di Indonesia tidak merata. Provider penyedia Telekomunikasi dan layanan internet di Indonesia belum dapat memenuhi kebutuhan infrastruktur di daerah terpencil. Solusi komunikasi yang berkembang cepat dan tanpa infrastruktur adalah MANET. MANET adalah sekumpulan node nirkabel yang bekerja sama membentuk jaringan. MANET terbentuk dari sekian banyak host yang terkoneksi melewati router tanpa inftrastruktur yang tetap dan berubah–ubah. Pada pengujian dengan 5 node, kemudian dilakukan analisis QoS dengan standarisasi TIPHON, didapatkan nilai Sangat Bagus Ketika diuji dengan paket 1500 dan 2000 byte mendapatkan nilai indeks lebih dari 3 di Delay, sedangkan Jitter mendapkan nilai Sangat Bagus disemua pengujian dengan nilai indeks diatas 3. Sedangkan Packet Loss mendapatkan nilai Sangat Bagus pada pengujian paket 1000 dengan nilai dibawah 3, pada pengujian throughput mendapatkan nilai TIPHON Sangat Jelek. Performa MANET dengan routing Babel layak digunakan model komunikasi alternatif karena masih mendapatkan nilai Sangat Bagus pada beberapa pengujian.

Currently, Madrasah Aliyah Negeri 2, Tangerang Regency, has problems memorizing chapter 30 as a mandatory requirement for school graduation. The system used today uses a manual and simple method by using a memorization card provided by the school. This makes students find it difficult in terms of managing the memorization track record that students take. Not only students, but teachers find it difficult because they do not have a clear track record related to memorizing juz al-Quran where the memorization card can be torn, wet and even lost. Based on these problems, technology is needed that can assist students and teachers in managing the track record of memorizing al-quran juz 30. The technology uses the Lean UX to solve problems in the User Interface My School Application Lean UX. Using the Lean UX will make it easier for the school to get faster feedback from students and develop systems that do not yet exist in the school. From the evaluation obtained, that the prototype of my school application using the lean ux method can be accepted by users because it produces a percentage of the average value of usability testing of 81% to 100%, it can be said that the category is very feasible , which is worth 82%. Then in the validity test average value is above 0.220, which means that the data is valid. Furthermore, the reliability test produces a Cronbach Alpha of 0.928, where the magnitude of the reliability factor ranges from 0 to 1, and the higher the reliability factor, the more consistent the measurement results.

The number of speakers of regional languages who are able to read and to write traditional scripts in Indonesia is decreasing. If left unaddressed, this will lead to the extinction of Nusantara scripts and it is not impossible that their reading methods will be forgotten in the future. To anticipate this, this study aims to preserve the knowledge of reading ancient scripts by developing a Deep Learning model that can read document images written using one of the 10 Nusantara scripts we have collected: Bali, Batak, Bugis, Javanese, Kawi, Kerinci, Lampung, Pallava, Rejang, and Sundanese. While previous studies have made efforts to read traditional Nusantara scripts using various Machine Learning and Convolutional Neural Network algorithms, they have primarily focused on specific scripts and lacked an integrated approach from script type recognition to character recognition. This study is the first to comprehensively address the entire range of Nusantara scripts, encompassing script type detection and character recognition. Convolutional Neural Network, ConvMixer, and Visual Transformer models were utilized and their respective performances were compared.Â The results demonstrate that our models achieved 96% accuracy in classifying Nusantara script types, with character recognition accuracy ranging from 93% to approximately 100% across the ten scripts.

Indonesia boasts a diverse range of indigenous scripts, called Nusantara scripts, which encompass Bali, Batak, Bugis, Javanese, Kawi, Kerinci, Lampung, Pallava, Rejang, and Sundanese scripts. However, prevailing character detection techniques predominantly cater to Latin or Chinese scripts. In an extension of our prior work, which concentrated on the classification of script types and character recognition within Nusantara script systems, this study advances our research by integrating object detection techniques, employing the YOLOv5 model, and enhancing performance through the incorporation of the U-Net model to facilitate the pinpointing of fundamental Nusantara script's character locations within input document images. Subsequently, our investigation delves into rearranging these character positions in alignment with the distinctive styles of Nusantara scripts. Experimental results reveal YOLOv5's performance, yielding a loss rate of approximately 0.05 in character location detection. Concurrently, the U-Net model exhibits an accuracy ranging from 75% to 90% for predicting character regions. While YOLOv5 may not achieve flawless detection of all Nusantara scripts, integrating the U-Net model significantly enhances the detection rate by 1.2%.

Sarang walet merupakan ekspor dengan nilai ekonomis yang tinggi. Tetapi, bentuk sarang walet yang dihasilkan juga mempengaruhi harga pembelian, seperti sarang yang terlalu kering maupun bentuk yang dinilai tidak sempurna oleh pembeli. Umumnya di dalam rumah walet terdapat kriteria pemeliharaan yang harus dipenuhi oleh pembudidaya sarang walet salah satunya adalah optimal nya sebuah sirkulasi udara. Suhu yang ideal atau stabil harus berkisar antara 26-29°C dengan kelembapan 80-90%. Kriteria lainnya ialah cahaya, umumnya walet tinggal di gua sehingga walet menyukai suasana tempat denga cahaya mendekati gelap atau nilai 0 lux. Kriteria selanjutnya adalah pH air, dalam rumah walet terdapat kolam yang digunakan untuk menekan kelembapan, selain itu kolam air ini bisa digunakan oleh burung walet mandi ataupun minum, dari hal ini tentu pH air yang normal sangat dibutuhkan. Dari permasalahan yang ada maka, penelitian ini bertujuan untuk memudahkan pembudidaya sarang walet dalam melakukan pemantauan suhu, kelembapan, cahaya, dan pH air di rumah walet menggunakan metode prototype, yang mana hasil monitoring dapat dipantau melalui website. Apabila suhu, kelembapan, cahaya, dan pH air tidak pada keadaan normal maka sistem akan memberikan notifikasi ke website pembudidaya sarang walet. Sistem ini menggunakan Internet of Things atau dikenal dengan IoT menggunakan NodeMCU ESP8266 agar dapat terhubung ke internet,selain itu penelitian ini juga menggunakan sensor DHT11 sebagai sensor yang digunakan untuk mengetahui besarnya suhu dan kelembapan pada rumah walet, sensor Light Dependent Resistor (LDR) untuk mengukur intensitas cahaya, dan modul pH air untuk mengukur tingkat asam atau basa dari air kolam di rumah walet, data dari sensor tersebut akan diteruskan ke web agar dapat dipantau oleh pembudidaya sarang walet. Berdasarkan penelitian yang sudah dilakukan, hasil pengujian selama 5 hari berturut-turut dengan jumlah sampel 1000 yang dilakukan pada siang hari dalam waktu 90 menit menghasilkan rata-rata 29,16 untuk suhu (normal), 78,6% untuk kelembaban (tidak normal), 0 atau gelap untuk cahaya (normal), dan ph 4,41(asam).
