The growth of technology in the last 3 years has been very rapid, as is the growth of smartphone use. This growth is directly proportional to the crime cases that occur, especially in Indonesia. There were a total of 12,835 case complaints from 2018 to 2020, and the most cases were online fraud cases with 7,560 reports related to fraud on cyber patrol sites. One of the crimes that often occurs is online fraud cases using fictitious transfer receipts. This crime was committed using one of the short messaging applications, namely Whatsapp. After the crime was successfully carried out, the perpetrator then deleted the evidence in the form of the conversation along with a photo of the proof of the transfer using one of the features on WhatsApp. Therefore, this study aims to obtain or acquire evidence on the Whatsapp application using the NIST (National Institute of Standards and Technology) method and applying the ELA (Error Level Analysis) technique to analyze evidence in the form of images obtained to strengthen the evidence in court. In facilitating the investigation process, a forensic tool is needed. The forensic tools used in this research are Magnet Axiom and ForensicallyBeta. The final result obtained is that Magnet Axiom managed to find some evidence, including conversation messages, victim contacts, call history, profile photos of the perpetrators, and pictures. With the help of ForensicallyBeta tools, the obtained receipt image can be analyzed and identified that there has been a modification to the receipt.

Paud Hidayatul Burhan is an Early Childhood Education which is located in Pasirtanjung Village, Lemahabang District, Karawang Regency. Currently, teachers are demanded to be creative in providing education to their students with various methods such as the rationalization of plant themes for fruits and so on. Due to the lack of educational facilities for this use of media, it is necessary to use technology to attract children's interest and motivation to learn. In this case, the fruit learning media still uses conventional methods such as books to see its shape in 2D. The method used in the application of augmented reality in this study is markerless, so that the black and white square markers are replaced by pictorial markers presented in the Augmented Reality Book (AR Book) containing strawberries, lemons and cherries. From the results of alpha testing, the application made can function properly. From the results of the marker test, the application can display 3D objects at a marker distance of 5 cm - 60 cm, with a marker tilt angle of 30 ° - 60 ° and the marker is blocked by other objects up to 75%. From the results of the questionnaire calculation using the Likert's Sumated Rating (LSR) method, a score of 85 was obtained, so the assessment range was very positive, which means that the application can be implemented properly. And also the calculations carried out by the author in the evaluation of students showed that Ho was rejected because there was no significant effect on children's understanding, while H1 was accepted because of a significant influence on children's understanding.

As a result of the implementation of social distancing rules, the education sector is forced to implement the Distance Learning system or study from home which sometimes makes students feel bored in its implementation. Therefore, an alternative learning media is needed to overcome this boredom. One method that can be used is learning through applications with the addition of augmented reality technology. The purpose of this study was to design an interactive learning media for early childhood based on augmented reality technology and to determine the impact of its use. This type of research is action research, while the software development method used is the waterfall model. This app is designed using Unity 3D and Vuforia SDK. The results of the calculation of the questionnaire, obtained a value of 98.6% which means the application is included in the very effective criteria according to the Likert Scale. And from the results of the paired t-test of application users before and after using the application, it was concluded that there were differences in the assessment of learning outcomes before and after using augmented reality-based basic learning applications for early childhood.

Abstrak— Pemilihan metodologi pengembangan sistem informasi adalah suatu hal penting yang perlu dilakukan sebelum membangun sebuah sistem. Pemilihan metodologi ini seringkali disesuaikan dengan lingkungan proyek yang kita hadapi, namun terkadang kita masih kebingungan dalam memilih metodologi apa yang sebaiknya digunakan agar sistem yang dirancang dapat memiliki kinerja yang baik dan efisien. Hingga saat ini, metode Waterfall merupakan yang paling populer digunakan, namun metode pengembangan tersebut bersifat kaku dan kurang cocok digunakan bagi lingkungan proyek dengan jangka waktu yang singkat. Sehingga, penelitian ini bertujuan untuk membandingkan penggunaan metodologi pengembangan sistem informasi yakni Waterfall yang dikenal sistematis, Agile yang dikenal tangkas, dan Hybrid yang merupakan gabungan dari kedua metode tersebut dalam pengembangan suatu sistem informasi, serta mengkaji lingkungan seperti apa yang cocok digunakan untuk ketiga model tersebut. Penelitian ini berupa Systematic Literature Review dengan sumber data yang dipakai pada penelitian ini didapatkan dengan bantuan perangkat lunak Publish and Perish 8. Lalu, didapatkan hasil bahwa metode Waterfall cocok digunakan untuk lingkungan proyek dengan skala yang tidak terlalu besar, metode Agile cocok digunakan untuk lingkungan proyek yang memiliki jangka waktu singkat, dan metode Hybrid bisa digunakan apabila membutuhkan keunggulan dari kedua metode yakni Waterfall dan Agile. Kata Kunci— Systematic Literature Review, Waterfall, Agile, Hybrid, Software Development Life Cycle
