Abstract

Regarding the problems faced by managers of the transportation business, namely cases of vehicle theft which still often occur, therefore an idea emerged on how owners can monitor their vehicles effectively, then accidents that usually occur due to reckless public transportation drivers due to influence of liquor. Based on the background described above, the authors aim to conduct research by creating a GPS tracking tool that is integrated with Arduino, which is able to monitor the location of the driver/vehicle and is able to reduce vehicle embezzlement, and the system to be designed is able to detect whether the driver of the vehicle is in a state of drink alcohol or not. Research has been carried out on 2 people, namely for the first person, the lowest sensor data reading was obtained, namely 22 ppm with a delay of 2 seconds for GPS readings for a distance of 3.5 km and the condition of the relay was off indicating that alcohol was not detected, and for the highest sensor data readings it was at 109 ppm with a delay of 3 seconds GPS reading for a distance of 4.2 km and the condition of the relay is on which indicates alcohol is detected. In the second person test, the lowest sensor data reading was obtained, namely 23 ppm with a 4 second GPS reading delay for a distance of 11 km and the condition of the relay was off indicating no alcohol was detected, and the highest sensor data reading was 121 ppm with a 2 second GPS reading delay for a distance 10 km and the condition of the relay is on which indicates alcohol is detected. GPS testing was carried out 10 times for each person where the longest distance tested on the first person was 42 km, and the shortest distance was 3.3 km. And for the test, the fastest delay in reading the driver's location is 2 seconds, and the longest is 5 seconds. In testing the second person, the longest distance was 12 km, and the shortest distance was 10 km. And in the test, the fastest delay in reading the driver's location point is 2 seconds, and the longest delay in reading the location point is 4 seconds.

Abstract

Due to high consumer demand, some traders use the high price of meat to make a profit by mixing pork and buffalo meat. Some consumers are not aware of this, because in plain view buffalo meat with pork meat is difficult to distinguish, especially for some ordinary people. This action is very detrimental and disturbing the local community, especially Muslims. At present, technological advances in the field of digital image processing are increasing rapidly, especially in food products. In general, this research was conducted in 2 (three) stages. The first stage, namely the stage of image data collection of pork and buffalo meat. The second stage, namely the classification of pork and buffalo meat images using image histogram analysis and the Gray Level Co-occurrence Matrix (GLCM) method based on the color and texture of the meat. In this study using the Red Green Blue (RGB) color image method and GLCM texture extraction, namely contrast, homogeneity, energy, and correlation. The study was conducted using 20 samples of meat images (10 images of pork and 10 images of buffalo meat, respectively). Based on the results of the research that has been done, it was found that the image of buffalo meat has a higher percentage value of the Red (R) color component when compared to the pork image, whereas the percentage value of the Green (G) and Blue (B) color components is lower when compared to the image pork. Then, if the value between pixels is not homogeneous (small homogeneity value), then the contrast value is large, and vice versa if the value between pixels is homogeneous (large homogeneity value) then the contrast value is small. The image of buffalo meat has a small homogeneity value compared to the image of pork, so the variation in intensity (contrast) in the image of buffalo meat is high.

Abstract

Banyak masyarakat kalangan menengah yang tidak mampu memberikan biaya pendidikan anaknya mencapai 9 tahun. Di sekolah terdapat program pemberian beasiswa PIP, namun sistemnya masih dijalankan secara manual yang menyebakan penyaluran beasiswa kurang tepat. Hal tersebut dikarenakan pihak yang diberi kepercayaan untuk menentukan beasiswa melihat kriteria-kriteria masih terpisah dan juga dipengaruhi calon penerima beasiswaa yang jumlahnya cukup banyak. maka dibutuhkan sistem yag bisa membantu sekolah dalam mengambil keputusan berdasarkan kriteria. Graph database sendiri bisa diartikan sebagai suatu model basis data yang didalamnya berisi node, relasi dan property. IMetode iAHP imerupakan isalah isatu imodel ipendukung ikeputusan, instrumen iutamanya iadalah hirarki ifungsional, dan iinput iutamanya iadalah ipersepsi imanusia. Dalam hal ini, mereka adalah ahli dalam menangani bab Beasiswa. Dalam AHP, prioritas terdiri dari berbagai pilihan yang berbeda dan berupa kriteria yang telah terstruktur sebelumnya, sehingga metode AHP dapat diandalkan. Jadi penentuan priioritas didasarkan pada proses yang hierarkis dan masuk akal. Pada penelitian ini penentuan bobot pada setiap kriteria seleksi beasiswa diambil dari yang paling tinggi nilainya yang akan diprioritaskan menjadi penerima beasiswa.

Abstract

Lighting is a vital requirement for elements of human activity, especially during productive hours of human activity. The important role of electricity in supporting the progress of lighting process technology, mechanical and other automation cannot be missed. Light is an electromagnetic wave consisting of a magnetic field and an electric field that are perpendicular to each other and light can also experience reflection, diffraction, refraction, polarization and interference. Light in its design is a lumen with flux units emitted in solid angle units by a source with a light intensity of one Candela. Lux is a metric unit of measurement for light on a surface. Efficacy is the average illumination / brightness achieved in a flat work area per watt in general lighting in the room expressed in lux/Watt/m2. Field studies, namely by observing and collecting data directly in the field for research objects on 40 watt LED lights installed in Solar Public Street Lighting on the Krisnadwipayana University Campus, as a reference for the design and installation and location of Solar Public Street Lighting placement. Testing the lighting data collection point (lux) is carried out to determine the angle of emitted lighting (lux) and the level of lighting radius obtained based on field data. As a result to find out according to standardization (SNI 7391; 2008). The street lighting for theenormous Solar Street in the parking lot of the Krisnadwipayana University Laboratory uses LED lamps with a flux of 5778 lumens and a power of 40 watts. The average lumen from the results of observations of data collection corresponds to the height distance between the LED 6 meters and the lux meter, and the angle of 5o is 53 lux.

Abstract

As the complexity of cloud infrastructure increases, one of the main challenges faced is how to optimize throughput in cloud networks. Optimal throughput is crucial to guarantee the performance of applications and services hosted in the cloud. Using load balancing techniques can optimize throughput, but careful analysis and testing is needed regarding the appropriate load balancing approach to improve throughput performance. This research aims to analyze the effectiveness of load balancing strategies with Round Robin and Least Connection in increasing throughput in cloud networks. Through empirical testing, this study compares the two methods based on the resulting throughput at various connection levels, ranging from 1000/600 to 5000/1000. Test results show that both strategies provide similar performance at low connection rates, with Round Robin recording slightly higher throughput at 1000/600. However, the difference becomes almost imperceptible as the number of connections increases. At 2000/700 to 5000/1000, the throughput generated by both strategies shows marginal differences, with Least Connection slightly superior at the highest connection level. These findings indicate that both Round Robin and Least Connection can be applied effectively to increase throughput in cloud environments, with the selection of specific strategies depending on workload characteristics and service requests. This research provides valuable insights for academics and IT practitioners who want to optimize cloud networks to achieve maximum performance

Abstract

BERT (Bidirectional Encoder Representations from Transformers) adalah model bahasa yang revolusioner dalam pemrosesan bahasa alami, mengandalkan encoder untuk menghasilkan representasi kontekstual dari teks input. Melalui pendekatan tokenisasi, embedding, dan attention mechanisms pada setiap layer transformer, BERT memungkinkan pemahaman hubungan antar kata secara mendalam dan bidireksional. Keunikan BERT terletak pada kemampuannya untuk memproses konteks dari kedua arah, menciptakan representasi vektor yang kaya makna. Model ini telah menjadi pionir dalam transfer learning di NLP, memungkinkan pemanfaatan representasi umum pada tugas-tugas khusus setelah proses pelatihan. Dengan demikian, BERT mengubah paradigma pemrosesan bahasa alami, membuka pintu untuk aplikasi yang lebih canggih seperti klasifikasi teks, analisis sentimen, dan pemahaman bahasa yang lebih kontekstual.
