Abstract

Currently, the changes in image quality resulting a low-resolution images, faded colors, and so on. This condition potentially attract irresponsible parties to take advantage of the situation for certain purposes. Nowadays, it is very easy for people to manipulate, change, or delete the original information from a digital image thus cause the authenticity and integrity of the image to be doubted. This study is conducted in a specific objective to prove the authenticity of a digital evidence for analysis by providing detailed illustrations of the role of Digital Forensics in accordance with applicable legal regulations in Indonesia using the NIST workflow. The research flow begins with uncovering the background of the problem, collecting data, making scenarios, applying the NIST method, and making conclusions. The illustration used in the scenario is a video inserted into a digital evidence. The video used in this research is the Cyanide Coffee Case with the suspect Wayan Mirna Salihin, happened in August 16, 2016 which was uploaded by Kompas TV channel on Youtube. The NIST analysis phases used several tools: Exiftools, Forevid, and Video Cleaner. The result indicates that all phases in the NIST method are correlated to each other. The result is specifically very clear in the collection phase. The discovery of hidden information causes the examination and analysis process to be more complex especially the extraction process of digital evidence in the form of images. Indeed, the use of various tools are more helpful in disclosing the existing information. This information can be seen from the results of metadata, hash value, and image sharpness from the analyzed digital evidence.

Abstract

Excessive use of electricity had some negative impacts. In this research, the Arduino ESP32 integrated with the WiFi module, the PZEM-004T V3.0 electric current sensor to detect the electric current used, DHT22 temperature sensor to measure the temperature and humidity of the room air, BH1750 light sensor to measure the intensity of light entering the room and SPDT Relay connected between the microcontroller and the lamp. Mamdani Fuzzy Logic Algorithm which was a cryptic system as part of the intelligent system methodology applied to control automation in fans with fuzzy input variables was temperature and humidity as well as the automation of lamp usage applied fuzzy logic mamdani with fuzzy input variables were the intensity of incoming light and the time zone. Defuzzy's calculation results based on rules and have been tested on fan and lamp automation obtained 100% accuracy. Aside from being automatic, this system were also applied manual control through the Blynk application only to the function (ON / OFF) and monitored real time electricity usage in the IDR value remotely with the Internet of Things method based on Microcontroller and IOS or Android. This research could help homeowners in saving electricity.

Abstract

Wireless Sensor Network is a wireless network technology that includes sensor nodes and embedded systems. WSN has several advantages: it is cheaper for large-scale applications, can withstand extreme environments, and data transmission is relatively more stable. One of the WSN devices is nRF24L01+. Within the specifications given, the maximum communication distance is 1.1 km. However, the most effective distance for transmitting data in line of sight and non-line of sight is still unknown. Therefore, testing and analysis are needed so that the nRF24L01+ device can be used optimally for communication and data transmission. Through testing analysis on nRF24L01+ line of sight, Kuta beach location in Bali and non-line of sight on the STMIK STIKOM Indonesia campus. The effective communication distance of the nRF24L01+ module in line of sight is between 1 and 1000 meters. The distance of 1000 meters is the limit of the effective distance for sending data, and the packet loss rate is less than 15% which is included in the medium category. Meanwhile, in the non-line of sight, the effective distance of the nRF24L01+ communication module is 20 meters, and the packet loss is close to 15%, which is a moderate level limit. With the analysis module, nRF24L01+ can be a reference in determining the effective distance on WSN nRF24L01+ in determining remote control equipment data communication.
