Security is a condition that is free from denger, every individual has the right to feel safe in daily life or activities. As time goes by, the security level can be disrupted or dangerous things can happen beyond prediction, in other words, it can happen suddenly, therefore of course there must be a system development as a medium for anticipating this. With the aim of develop the system, it is necessary to design a system that can reduce crimes that are beyond human expectations. This system is called the Smart Security System which is a development of CCTV in general, this system uses cameras and smartphones as information media that will provide notifications to each individual to get notifications regarding real-time conditions in areas under camera surveillance via telegram. This system is assisted by Machine Learning in the form of OpenCV which is programmed on a Raspberry pi4 device which is connected directly to the camera to detect people ormovement in areas under CCTV monitoring so that it can immediately provide information to users which is sent via telegram in the form of video. It is hoped that with this system the level of security can be more effective so as to reduce the risk of theft in a room. From the results of the tests that have been carried out, it is found that to determine the effectiveness of the work of this study, an optimal distance is needed with a minimum distance range of 2 meters - 10 meters from the front of the camera and bright lighting

Proses manufaktur PCB melibatkan banyak proses salah satunya yaitu Surface finishes. Salah satu jenis Surface finishes yang biasa digunakan yaitu Immersion tin. Immersion tin adalah salah satu proses Surface finishes yang menggunakan timah murni pada prosesnya. Immersion tin berfungsi melindungi tembaga dari oksidasi dan membuat permukaan tembaga atau pad mudah disolder. Kebersihan pad dan ketebalan hasil Immersion tin mempengaruhi kualitas PCB yang dihasilkan. Oleh karena itu peneliti melakukan evaluasi kualitas hasil proses Immersion tin dengan menggunakan metode DOE (Design of Experiment). Dimana metode ini dapat membantu dalam menentukan parameter yang optimal. Untuk Variabel yang digunakan yaitu Storage Time After Microetch dan Immersion in tin Bath. Dalam proses penelitian didapatkan PCB mengalami perubahan morfologi pada 23 jam setelah disimpan di storage. Hal tersebut disebabkan oleh adanya kelembapan yang masih terdapat pada PCB akibat dari kurang maksimal pada saat proses pengeringan (drying). Pada penelitian ini Solder Coating Thickness yang optimal pada sampel ke-14 dengan hasil sebesar 4.59 µm dan dengan parameter Storage Time After Microetch selama 50 menit dan Immersion in tin Bath selama 120 menit. Untuk kebersihan pad yang paling optimal terdapat pada sampel ke-5 dan ke-12 dengan parameter Storage Time After Microetch selama 30 menit dan 60 menit dan ditandai dengan tidak adanya kontaminan pada pad tersebut. Selain itu juga, Pada penelitian ini terdapat hasil mapping yang kurang optimal ditandai dengan hanya terdapat 1 bagian dari 1 sampel yang terkandung timah dari 16 sampel pengujian. Sampel tersebut yaitu sampel ke-3 dengan parameter Storage Time After Microetch selama 10 menit dan Immersion in tin Bath selama 55 menit dengan kandungan tin yaitu 91.9 %.

The increasing demand for parking spaces in various facilities, such as shopping centers, ports, and airports, poses a significant challenge for parking managers. Drivers waste time and fuel searching for available parking slots, resulting in increased air pollution and negative environmental and health impacts. Therefore, a new solution is needed to address these issues and improve parking management efficiency. A parking management system that utilizes RFID technology and allows for the RFID Tag on each car to display user data, user ID, and parking space reservations is needed to improve the efficiency and convenience of parking at various facilities. The proposed system design incorporates various components, including a Camera Sensor, Raspberry PI, ESP8266, UHF RFID reader, and RFID Tag. The RFID technology captures radio waves emitted by the RFID Tag, enabling individual identification through unique codes. Testing revealed high accuracy at close range but decreased effectiveness at longer distances. Internet speed and network latency affected system performance, with faster speeds enabling faster data transmission. The system, developed using Thunkable and Firebase, provides real-time parking space availability information and streamlines vehicle entry and exit processes through RFID technology. This system has the potential to greatly improve the parking experience at busy public facilities by facilitating efficient parking spot finding and enhancing overall convenience for drivers.

Kode label pada sebuah proses produksi memiliki fungsi penting untuk pengidentifikasi (identifier). Pembuatan kode label pada leadframe dapat dilakukan dengan metode laser engraving ataupun painting. Chip RFID dipindahkan pada media leadframe untuk membawa sinyal dari level die menuju rangkaian diluar. Uji fungsi konduktifitas dilakukan untuk memastikan bekerjanya rangkaian setelah proses die attach dan wire bond dari chip RFID. Berdasarkan studi kasus pada TFME, hasil uji fungsi ini disimpan dengan pemberian label yang masih manual. Metode template matching diterapkan untuk membaca kode label leadframe yang kemudian akan dipindai dalam bentuk laporan teknis pengujian. Sistem identifikasi label ini dengan Raspberry Pi 3 dan dilengkapi kamera Sony IMX219V2 dengan resolusi 8 MP. Dua karakter yang mirip yakni angka 2 dan Z dieliminasi dari sample. Selain itu kode label dibuat dalam karakter dengan garis vertikal dan horizontal. Hasil pengujian menunjukkan tingkat keberhasilan pembacaan sebesar 100%. Kode label yang telah teridentifikasi ini selanjutnya menjadi nomer identifikasi leadframe dalam bentuk report file yang disimpan dalam format dokumen.

The study presents the investigation of the elastic behavior of the soil in the optimal design of continuous foundations according to the rigid solid case. For the investigation, the optimization algorithm that can find optimal section and reinforcement details of continuous foundations has been developed. The developed algorithm uses one of the well-known meta-heuristic methods named the artificial Bee Colony method to find the optimal design. The Winkler spring hypothesis (analytic solution) is used to calculate internal forces and stresses in elastic continuous foundations. We used the real-size design example previously used in the literature to test the elastic soil effect and algorithm performance. The obtained results show that the current algorithm performs well, and lower cost values are obtained in the elastic design.

Attenuation, time lag, outflow peak and storage are very essential factors required in flood risk prediction and flood pattern. However, the accurate prediction strongly depends on appropriate calibration of routine parameters of the model, such as weighting factor (x) and storage time constant (K). The weighting factor being used to determine storage time constant has not been given consideration in the previous studies and this could have led to inaccurate prediction in the past. In this work, a set of data obtained from an ungauged Awara river in Ondo State, Nigeria were used to test the effects of a weighting factor, x at levels ranging from 0.1-0.5 at interval of 0.1. The Muskingum model was used to obtain the storage and weighted discharge storage. It was observed that the correlation coefficient (R2) decreases with an increase in the weighting factor (x). This implies that there is a strong relationship between storage and weighted discharge storage at 0.1-0.3 levels of x while, the relationship is fair at 0.4-0.5 levels. It is therefore appropriate to choose a value of x ranging between 0.1 and 0.3 for attenuation prediction, while values of x ranging between 0.4 and 0.5 would be appropriate for accurate prediction of both outflow peak and storage.

In this first study, the rectangular reinforced concrete beam’s costs and cross-section sizes are found by using Harmony Search (HS), Differential Evolution Algorithm (DE), Jaya Algorithm, Teaching- Learning Based Algorithm (TLBO), Hybrid algorithm (Jaya-TLBO) and Flower Pollination Algorithm (FPA) separately by using ACI 318 building code. In addition, in order to better see how successful the algorithms are, the standard deviation of the algorithms used in the project in a certain number of iterations, price changes and in which iteration the minimum cost is compared. As a result of running different algorithms 5, 10, 15 and 20 times, separate values are recorded, and the average number of iterations of the algorithms for each is shown by finding the standard deviation values. Furthermore, Hybrid Algorithm reached the objective function in fewer iterations and their standard deviations reached 0 earlier. In the second study, the beam design is made according to the ACI 318, TS500 and Eurocode 2 regulations under certain loads by using a Hybrid Algorithm with different concrete classes. Optimization of this design is made using the Matlab program, and comparisons are made between regulations. Eurocode and TS500 design costs are roughly the same; however, ACI 318’s design is the cheapest.

As a result of running different algorithms 5, 10, 15 and 20 times, separate values are recorded, and the average number of iterations of the algorithms for each is shown by finding the standard deviation values. Furthermore, Hybrid Algorithm reached the objective function in fewer iterations and their standard deviations reached 0 earlier. In the second study, the beam design is made according to the ACI 318, TS500 and Eurocode 2 regulations under certain loads by using a Hybrid Algorithm with different concrete classes. Optimization of this design is made using the Matlab program, and comparisons are made between regulations. Eurocode and TS500 design costs are roughly the same; however, ACI 318’s design is the cheapest.","PeriodicalId":34399,"journal":{"name":"International Journal of Electrical Engineering and Applied Sciences","volume":"124 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83516986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
