Computer Vision is one of the branches of Image processing science that allows a combination of human beings, such as identifying an object like an eye and taking a decision. Many of the face detection systems use the Viola Jones method as an object detection method. The method of Viola Jones is known by having high speed and accuracy because it is useful to combine several concepts such as (Haar Features, Integral Image, AdaBoost, and Cascade Classifier) into a major method for detecting objects. The programming language used in this study uses the MATLAB programming language to facilitate the process of creating the system. The research aims to implement Viola Jones into a simple eye-sensing drowsiness system by utilizing the existing libraries in the MATLAB programming language. Once the system is completed, a system test is performed against the detected drowsiness detection characteristics. This eye drowsiness detection system aims to determine if the car rider is sleepy or not when driving with an input in the form of eye detection taken using a digital camera and then inserted into a language Programming GUI Matlab where the value is taken binary eyes, sleepy eyes and not sleepy that will be a reference that will be processed later so that it can produce the output of a warning sound to the rider of the sleepy car vehicle or not The sleepy automatically. The testing of the program gained an amount detected 7 eyes of 10 eyes by using BW 0255 level which is useful to accelerate a program to detect sleepy eyes.

Kampung Selamat is one of the villages in Tenggulun Sub-district, Aceh Tamiang Regency, which is 45 kilometers from the capital city of Aceh Tamiang. Most of the villagers work as farmers and breeders. Kampung Selamat has high natural resource potential in the livestock sector, but has not been managed optimally. The Dunia Ternak Unggas group is one of the productive livestock business groups in Selamat village that was established in 2019 with the main focus of developing chicken farming. The problems faced by the World Group of Poultry in business development include; (1) The process of hatching chicken eggs is still conventional, which still requires mother chickens; (2) It takes a long time to hatch eggs; (3) The risk of eggs not successfully hatching is still very large; (4) The process of checking chicken eggs is still manual, namely looking directly at the location; and (5) limited land so that the layout of hatching chickens is uncontrollable. To face these challenges, it is necessary to develop hybrid smart eggs incubator technology that can significantly help livestock business groups in increasing chicken productivity and simplifying the breeding process. The steps of implementing the activity include the socialization stage, design and manufacture of tools, as well as training, mentoring, and application of these devices. The results of the implementation of this activity indicate that the level of user satisfaction with the IoT-based hybrid Egg Hatching Machine Incubator reached an average of 87.93%. This fact illustrates that this tool is a solution that is worth adopting to increase efficiency in the hatching process of chicken eggs and has the potential to produce a positive impact on chicken farming and provide solutions to the obstacles faced by livestock business groups.

Hydrological analysis in urban areas often suffers from inaccuracies in Digital Elevation Model (DEM) interpretation, especially in detecting micro-depressions and small-scale surface flow patterns. Previous studies typically relied solely on the automatic D8 algorithm in GIS without manual verification, resulting in flow directions that do not fully represent actual surface conditions. This study aims to compare manual D8-based flow direction calculations with automatic ArcGIS processing using DEMNAS data for Langsa City. The DEM (8.1 m resolution) underwent sink filling, hydrological conditioning, slope and aspect processing, followed by field validation using GPS measurements. The results show that the manual method identified 23 flow paths, whereas ArcGIS detected only 11. The differences stem mainly from micro-topographic variations that the automatic algorithm failed to capture in flat areas or anthropogenically modified surfaces. Field validation confirmed that 8 of the 11 ArcGIS-derived paths matched the actual drainage patterns, while the additional manual paths better represented subtle elevation gradients.This research contributes by offering a systematic comparison between manual and automatic D8 approaches, highlighting the importance of manual verification in low-slope urban terrains. The findings are valuable for micro-scale flood mitigation planning and urban surface hydrology analysis.
