Smartphone retail sales in Indonesia are currently growing very rapidly. Point of Sales Material (POSM) is used to provide information about products to consumers, using displays to stimulate impulsive buying behavior. This study designed a 3D planogram visual media, which can visualize real-time with text, images, and videos. Media that has been developed by researchers is in the very good category with a percentage of 78% for the promoter segment that is more than 1 year and 77% for the new promoter segment who has worked at Samsung retail for less than 1 year. From the results of experalidation and user validation, for the aspect of video visualization and the 3D planogram module that has been developed, the category average AB score is 81-85. The display arrangement process can be done more quickly and precisely because the understanding of the planogram increases.

The development of technology allows one to obtain other people's spatial position data. One mobile technology that utilizes spatial data as a supported factor is location-based services. The large number of employees at the PT.XYZ causes the presence of a controlled process to be under control, and even tends to be questioned. Because it takes a GPS-based presence system on android that is expected to be a solution of the problems that occur at this time. The system development method used is a six-step R&D method, consisting of: Research and information gathering, Planning, Development of initial product forms, initial field testing, major product revisions, main field testing. The final result is the prototype of the Ganesha Employee Presence System Operations. The test results on the system shows the employee attendance system can run on the android platform. The system only responds to presence based on the position of the employee's coordinates with office coordinates. Besides checking the presence process is also based on devices that have been approved in the system. 

The purpose of this study was to determine the effect of the forensic accounting and audit investigations in detecting fraud procurement of goods and services. The rise of fraud cases in Indonesia, one of which is fraud related to public needs, namely the procurement of goods and services. This is reminiscent of the real threat of fraud in the form of corruption in the procurement of goods and services that can cause poor quality of goods / services produced so that they cannot serve the public interest effectively and efficiently. In this context, the community is the most disadvantaged party. Collecting data in this study through the distribution of questionnaires with a total sample of 34 auditor respondents in the field of Investigation of the Badan Pemeriksa Keuangan dan Pembangunan DKI Jakarta. This research uses PLS (Partial Least Square) analysis technique, using SmartPLS software testing tool version 3.2.8. The results of this study indicate that the results of the analysis of the application of forensic accounting and investigative audits have a significant effect in detecting fraud procurement of goods / services.

Pembelajaran bahasa Inggris di taman kanak-kanak merupakan fenomena pendidikan. Poin yang paling menonjol adalah kemampuan untuk mempelajari bahasa baru dengan cepat. Anak-anak menggunakan berbagai jenis sumber daya mental untuk memasukkan kata dan makna. Mereka melakukan interpretasi terhadap yang didengarkan dan diamati di sekitar. Guru memainkan peran penting dalam membina perkembangan intelektual dan sosial anak. Pendidikan yang diperoleh siswa adalah kunci untuk menentukan masa depan siswa tersebut. Salah satu tugas guru ada membuat rancangan pembelajaran. . RPP adalah pedoman bagi guru untuk melaksanakan proses pembalajaran di kelas. Pengembangan dan perubahan kreatif dapat dilakukan untuk menyesuaikan kebutuhan siswa dalam proses pembelajaran Bahasa Inggris. Metode pelaksanaan merupakan landasan atau acuan agar proses dalam program pengabdian kepada masyarakat ini berjalan secara sistematis, terstruktur, dan terarah. Setelah proses observasi lapangan dan identifikasi permasalahan dilakukan, maka akan dilakukan perancangan solusi. Selanjutnya solusi yang menjadi yang telah direncanakan akan ditawarkan kepada mitra. Metode yang akan digunakan dalam program ini Survey, Implementasi, dan Evaluasi.Pelatihan ini diberikan kepada guru-guru di KB TK IT Alif Smart Kadipiro Surakarta. Hasil dari pelatihan ini adalah berkembangnya kemampuan guru dalam membuat rancangan pembelajaran bahasa Inggris untuk KB dan TK. Produk yang dihasilkan yaitu berupa RPP pembelajaran Bahasa Inggris untuk KB dan TK.

Augmented Reality (AR) and Virtual Reality (VR) which are one of the top ten strategic technology trends for 2019 and continue to be developed massively in this 2020, have been widely applied in various mobile applications by many companies in this industrial revolution era 4.0. AR can be applied to help the promotion for housing developers where users can see the 3-dimensional shape of the types of houses offered, while VR allows users to explore each part of the house in a virtual 3D. Pre-existing brochures are used as markers for this application to work, so that AR and VR applications can be a complement to promotional media. The design method used in this paper is Research and Development (RnD). Salespeople can offer types of houses to prospective customers without having to print multiple brochures, but with just one brochure and one android smartphone to present, so the promotion costs are more efficient.   Keywords: AR, VR, house.

In the daily use of technology, humans cannot be separated from the internet as a need to exchange information. People at this time spend more time in front of computer screens, laptops, even smartphones to find out information, send data to some of their friends. One of the information that is often sought or sent is a file. Apart from that, image files are files that are much searched for and sent, and many also contain important information in them. Image file security is of course very important so that unauthorized parties do not hack or manipulate information from the image. There is a way to secure information so that it does not leak to unauthorized parties, namely by using cryptography and steganography. By combining these two methods, you can maintain the confidentiality and security of a file, especially image files. In this study the algorithm and method used is the AES cryptographic algorithm (Advanced Encryption Standard) 256 and the LSB (Least Significant Bit) steganography method. Data integrity needs to be tested to ensure that the encryption and decryption processes are running properly. Data integrity testing uses the SHA-1 method. Likewise, the image quality after insertion will experience a decrease in quality. To evaluate this, it is necessary to test using the PSNR method. From the results of data integrity testing by comparing the hash value of the decrypted image file with the original image file, there is no difference. So this shows that the encryption and decryption process was successful. While in testing using the PSNR method, the average PSNR value is 44.14086 dB and with an average error value of 2.830403 dB, which means there is a small decrease in quality. From the implementation and testing results, it can be concluded that the AES 256 cryptographic algorithm and the steganography method LSB can be implemented in maintaining the confidentiality and security of secret messages.
