    Studi ini mengeksplorasi cara meningkatkan produktivitas sayuran daun hidroponik dengan menyeimbangkan Total Padatan Terlarut (TDS) dan pH larutan nutrisi. Menggunakan pakcoy dalam sistem rakit apung, penelitian ini menerapkan desain eksperimental terkontrol untuk mengamati bagaimana parameter-parameter ini berinteraksi dalam mendukung pertumbuhan vegetatif dan hasil panen. Pemantauan harian dan penyesuaian tingkat nutrisi dan pH yang cermat ditekankan untuk memastikan penyerapan nutrisi yang optimal. Kondisi TDS dan pH yang seimbang meningkatkan pembentukan daun dan akumulasi biomassa, sementara ketidakseimbangan menyebabkan stres nutrisi dan penghambatan pertumbuhan. Studi ini menawarkan panduan praktis bagi petani untuk menyinkronkan TDS dan pH secara real-time guna meningkatkan pengelolaan nutrisi. Temuan ini berkontribusi pada hidroponik presisi yang selaras dengan pertanian berkelanjutan, khususnya mendukung tujuan pembangunan berkelanjutan (SDGs) untuk SDG 2 (Tanpa Kelaparan) melalui produksi pangan yang efisien dan SDG 12 (Konsumsi dan Produksi yang Bertanggung Jawab) dengan mendorong penggunaan input pertanian secara optimal. © 2026 Universitas Pendidikan Indonesia.

  • A Comparative Algorithm Study Using Titanic Dataset for Best Accurate Prediction

    Authors: Wahyudin; Dwi Fitria Al Husaeni; R. Rasim; Hanhan Maulana; Shah Nazir

    DOI: 10.1109/ICIC64337.2024.10956979

    Abstract

    The Titanic is a British cruise ship that is claimed to be the largest ship ever built in world history. The ship struck an iceberg on its maiden voyage across the Atlantic in 1912 from Southampton to New York. Of the more than 2.200 passengers, almost half died in this tragic accident. This famous incident prompted scientists to research more about the event. This research aims to analyze data and understand the factors that influence passenger survival. Using Machine Learning techniques and a data set consisting of 891 records, researchers tried to determine the relationship between factors such as age, gender, passenger class, and ticket price. This research uses various machine learning algorithms such as Random Forest, Optimize Selection, and Optimize Features to predict the accuracy of each algorithm. These factors may influence passenger survival rates. Specifically, this research aims to compare algorithms based on the percentage accuracy of test data. The research results show that the highest accuracy is achieved by the Random Forest algorithm with weight optimization using Particle Swarm Optimization (PSO). © 2024 IEEE.

  • Design of Interactive Learning Media to Pronunciation Characters and Words English for Blind Children

    Design of Interactive Learning Media to Pronunciation Characters and Words English for Blind Children

    Author: Syahrul ; Wicaksono M.F.; Hidayat

    DOI: 10.1088/1757-899X/407/1/012096

    Abstract

    This paper aims the study of designing an English learning system for blind children. Instrument designed is interactive learning media so hopefully blind child will be easy to be interested and active to learn. The processing hardware used is Raspberry Pi (as its main brain). Learning system mode is made of two kinds, namely learning mode (text to speech method) and question mode (speech to text method). The result of this research is a model for learning letters recognition and English pronunciation tool. The design of this tool using Raspberry Pi 3, because the Raspberry Pi 3 is a computer system that is integrated with the supporting components required in voice recognition processing and text to voice conversion. The design of this model does not cost much, because it only uses a Mini PC that is Raspberry Pi 3 as the main component. However, in previous research, interactive learning of braille for children using linguistics requires a lot of hardware and requires teachers in its use. the learning media is expected to help the blind child in learning the characters and English words and also expected this instrument can be used for use in the school blind. © Published under licence by IOP Publishing Ltd.

    Author: Kurniawan B.

    DOI: 10.1088/1757-899X/407/1/012097

    Abstract

    The purpose of the study was to integrated information system for radio frequency identification based adMinistration and academic activities on higher education. Technology based on Radio Frequency Identification (RFID) in the environment industry and in the environment of education has been widely applied. In, using the RFID system has penetrated many sectors, from manufacturing, distribution, retail goods storage, hospitals and education. RFID system in Environmental Education has been widely used for Student ID Card, library, attendance and for control of the room automatically. However in the application/usage of RFID system is still designed/designed separately which can lead to instability of the interbank data system built. To fix the issue, conducted a study on the use of RFID technology is integrated to academic and adMinistrative services that are required. System academic adMinistration and service that will enhance any RFID functions used in the transaction. With many RFID data from each service, an integrated RFID information systems needed to manage and monitor any data services. The data used in any transaction using the academic adMinistration and service system will increase every time the RFID is used in the transaction. The RFID data with quite a lot of any services, either for an absences, the student, library services and parking service system, integrated RFID information systems needed to manage and monitor each data service. This integrated information system serves to academic and adMinistrative services under the RFID platform. With this information system, data processing as well as academic and adMinistrative services into a more effective and efficient. In addition to the data management, integrated information system can help in making the report and provide the necessary information to other systems that need to support specific strategic decisions related to adMinistrative services and the academic. © Published under licence by IOP Publishing Ltd.

    Author: Hardiyana B. ; Yudistira R.

    Abstract

    The purpose of this study was to show the application of IPS learning about humans and geographical environment based on multimedia. Educational media in children with special character compared with children is needed, therefore the teachers in extraordinary schools (SLB) prohibit interesting, creative and positive methods, so that the participants can help the learning activities, the learners which is deaf people does have a shortage in hearing, hence the most effective way is with multimedia visual methods, especially in social science lessons (IPS) Geography is quite difficult to be implemented in a dialogue between teachers and students especially in SLB-B Prima Bhakti Mulia where they are in their learning using oral methods. They can help in learning. In designing the application using descriptive research method, object oriented approach method and prototype development method. So with the method can provide information about the object and the procedure studied. The result of this research is a multimedia-based learning application that is implemented using Adobe Flash CS6 Professional. Has an advantage in the more interesting lessons of human relationships with the economic environment and may be used as a method of therapy for children with special needs. © Published under licence by IOP Publishing Ltd.

    Authors: MeLian L. ; Nursikuwagus A.

    DOI: 10.1088/1757-899X/407/1/012140

    Abstract

    This research is proposed about decision in eligibility for accepting and rejecting student in vocational school. Prediction is one area in data Mining that discuss about classification. One method of algorithm in prediction is Naïve-Byes Decisions Algorithm. Variable will be counted by Naive-Byes Decisions algorithm that content of final exam, report, psychology, interview, and competency. Execution for the first step is transforMing each variable into ranging values. Step forward is continued to calculate possibility value for every variable. In 270 student, the research has been resulted the validation test is 199 same as actual condition. Precision is 96,1%, recall is 99,3%. The result is meaning that the algorithm has ability to get the decision in accepting manner with 74,87% accuracy. The value gives the reasoning that has not all submitting students are accepted by the school. Meanwhile, the algorithm has giving fair process for accepting the candidate. The impact of this research is the school can predict how many students is accepted and rejected. So, school will prepare for how many rooms should be available. © Published under licence by IOP Publishing Ltd.
