Abstract

ABSTRAK   Penelitian ini bertujuan untuk mengaplikasikan pemrosesan citra digital dan jaringan syaraf metode LVQ guna menghasilkan sebuah perangkat lunak deteksi uang palsu. Citra masukan berupa citra penari yang muncul dari uang kertas limapuluh ribuan rupiah akibat pendaran cahaya lampu ultraviolet. Metode penelitian meliputi studi literatur yang berkompeten, metode pengumpulan data citra uang palsu dari bank-bank konvensional, dan implementasi pengkodean menggunakan bahasa pemrograman Visual. Citra ciri bergambar penari berukuran 90x114 piksel dilekstraks nilai RGB-nya. Nilai RGB ini menjadi variabel masukan bagi LVQ. Hasil yang diperoleh dari penelitian berupa perangkat lunak deteksi uang palsu berbasis LVQ, dengan keberhasilan pendeteksian hingga 100% baik pada 20 buah data citra uji iluminasi maupun 14 buah simulasi data citra uji kecerahan. Data citra uji iluminasi terdiri dari 10 citra uang palsu dan 10 citra uang asli. Data citra uji kecerahan terdiri dari 3 citra uang asli dan 11 citra uang palsu. ABSTRACT This research is aimed to colaborate digital image processing and neural network using Linear Vector Quantization (LVQ) method to make a money counterfeit system detection. The input image of the system is the dancer object image of Rp. 50.000,- money fluorescend by ultraviolet light. The acquisition data was taken from conventional banks. The LVQ method was used to recognize whether the money being recognized is conterfeit or not. The coding was carried out using visual programme language. The size of the dancer recognized object  was in  90x114 px, and its RGB was extracted. The experimental results show that the system has an accuracy 100% of detecting 20 real test case data, as well as detecting 14 simulated test case data. The simulated case data was generated by varying the brightness of the data image. The real test case data contains of 10 counterfeit money and 10 original money. The simulated case data contains of 3 original money and 11 counterfeit money. Keywords:      detection system, counterfeit money, neural network, LVQ, digital image processing

Abstract

This research is aimed to test a paper currency counterfeit detection system based on Linear Vector Quantization (LVQ) Neural Network. The input image of the system is the dancer object image of? paper currency Rp. 50.000,-? fluorescent by ultraviolet light. The image of paper currency data was taken from conventional banks. The LVQ method is used to recognize whether the paper currency being tested is counterfeit or not. The coding was carried out using visual programming language. The? feature size of the dancer tested object is 114x90 px and the RGBHSI was extracted as the input for LVQ. The experimental results show that the system has an accuracy 100% of detecting 20 real test case data, and 96% of detecting 22 simulated test case data. The simulated case data was generated by varying the brightness of the? image data. The real test case data contains of 10 counterfeit paper currency and 10 original paper currency. The simulated case data contains of 11 original paper currency and 11 counterfeit paper currency. The best setting for the system is? Learning Rate = 0.01 and MaxEpoh = 10.

Abstract

Parasitic diseases usually attack cattle or sheep, which can cause a decrease in livestock productivity. One of the parasitic diseases that arise is caused by the cage's cleanliness and poor management of faecal waste. This community engagement activity aims to increase farmers' knowledge about ruminants' parasitic diseases and train them to produce organic fertilizer from cow faeces. The activity was carried out at the Putra Rahayu Cattle Group Farmers in Tawangrejo Village, Jatipurno District, Wonogiri Regency. Activities included conveying information about parasitic diseases and training on making organic fertilizer from cow faeces. This livestock group has 25 members. All participants participated in the activity enthusiastically. As many as 28.6% of respondents already know how to make organic fertilizer. All participants did not know about parasitic diseases. After counselling and training, farmers' knowledge increased by 72.4% about how to make organic fertilizers and increased 100% of their knowledge about parasitic diseases in livestock. The results of the cow faeces test found that Toxocara sp., strongyle and trematode parasite eggs were then given a grant in the form of parasitic drugs for ruminants. This activity concludes that farmers' knowledge of parasitic diseases and organic fertilizers increases.

Abstract

Abstract The world is currently undergoing a transition process from Industrial Revolution 4.0 to Industrial Revolution 5.0. Preparation is needed, especially in the field of education to provide learning programs related to automation technology. The training was conducted at MA Al Madinah Boyolali. Data collection methods through questionnaires were used to analyze the effect of providing this training program in improving students' understanding of the basics of automation. The training was incorporated into the school's extracurricular which were held once a week. There were 3 basics automation projects: automatic light based on PIR sensor, automatic parking sensor based on ultrasonic sensor, and automatic clothesline. The training stages began with pre-test, introduction to Arduino, projects, trials, final exam, and post-test. The training provided 89.22% understanding to students, with a great predicate. Training on the basics of automation is needed for students as a preparation for global challenges and the Industrial Revolution 5.0. Keywords: Arduino, automation, training Abstrak Dunia saat ini sedang mengalami proses transisi dari Revolusi Industri 4.0 ke Revolusi Industri 5.0.

Abstract

Public places that provide a secure, welcoming, and beautiful environment are becoming increasingly important to enhance community welfare. The government is attempting to enhance public services in Salatiga's Tingkir sub-district by creating an integrated public space design for the neighbourhood. Presenting this integrated public space is difficult as it must allow for various community activities in a typical community area, including sports, education, recreation, and events. In response to this problem, a passive design strategy that optimises building operations and conserves resources by considering context and microclimate elements is given in the design of a public space. These include modifications to the traditional Javanese stilt house form, skylights for daylighting, and roof protection against predicted excessive rains and sunshine. Integrated public space planning aims to fulfil many communities' requirements and provide a visually stunning and sustainable environment for everyone via these strategies. This study's most effective passive design techniques are adapting the traditional stilt house model to increase natural ventilation on artificial cooling systems and roof protection as shading, which can effectively regulate temperature. These methods are anticipated to enhance public spaces' overall sustainability and livability, transforming them into ecologically conscious and neighbourhood-focused hubs of activity and engagement.
