Currently, the food ordering process is done with customers coming to the canteen cashier. However, this ordering method often encounters problems when there are many customers who want to order food, such as mixed-up orders due to the lack of order recording. The objective of this research is to create an Android-based food sales system that can transform the previously manual sales system into a computerized one. The food sales application at Citra Cafe's cafeteria is a system that provides convenience in ordering food and reduces errors such as mixed-up orders. For this research, a qualitative approach is implemented using the prototype method for system development. To gather data, this study utilizes interview techniques and observations to obtain processable data that can be used to design the system according to the requirements. Furthermore, this research also applies blackbox and whitebox testing methods to test the designed system. With the implementation of this food sales system, it will ease the cafeteria attendants' work in managing customer orders, eliminating mixed-up orders, and facilitating customers in ordering food as they no longer need to queue in front of the cashier to place their orders.</em></p> Wahyu Santoso, Fajar Agung Nugroho Copyright (c) 2024 Wahyu Santoso, Fajar Agung Nugroho https://journal.mediapublikasi.id/index.php/oktal/article/view/3076 Mon, 09 Sep 2024 00:00:00 +0000 Rancang Bangun Aplikasi Website Desa Untuk Pelayanan Publik (Studi Kasus Desa Kwasen) https://journal.mediapublikasi.id/index.php/oktal/article/view/3733 <p><em>Kwasen Village is one of the villages in Kesesi District, Pekalongan Regency which carries out public service activities in the form of administration every day.However, local village officials still use the manual method for the data collection process where residents come to the village hall after which their personaldata will be recorded and recorded by writing on paper notes. visit the village hall to carry out administrative activities which will take up their time.To overcome this problem, an information system is needed that can handle data storage and administrative activities in a timely manner that is effective enough.Making a web-based information system by relying on the JavaScript language and the nodeJs framework with the aim of providing convenience and a way out for residents and village officials so that data collection and administrative activities can be more efficient in terms of time and secure in filing.</em></p> Ahmad Ahsam Rozaq Copyright (c) 2024 Ahmad Ahsam Rozaq https://journal.mediapublikasi.id/index.php/oktal/article/view/3733 Mon, 09 Sep 2024 00:00:00 +0000 RANCANG APLIKASI TOKO JAHIT MAMA ABIL COLLECTION BERBASIS WEBSITE https://journal.mediapublikasi.id/index.php/oktal/article/view/3738 <p>Mama Abil<em> Collection sewing shop is a small business specializing in women's fashion garment tailoring services.

However, traditional agricultural systems face many challenges, including low productivity; traditional farming may not be as productive as modern methods. Additionally, dependence on weather conditions poses a significant barrier to production. To improve the quality and productivity of traditional agriculture, methodologies such as developing smart farming systems can be implemented. Smart farming applies technology in agriculture to enhance efficiency, productivity, and sustainability through sensors and IoT devices to manage and monitor agricultural activities more effectively. The smart farming system to be developed is based on the SCADA concept, where control of devices such as temperature sensors, soil moisture, light, and rainfall sensors, as well as actuators, is managed via the ModBus protocol based on the RS-485 RTU module. For controllers connected to the internet server, the ESP32 module will be used. Users can access the system using smartphones or laptops equipped with a wireless modem to establish remote connections via the internet. Thus, the application of this technology can significantly increase agricultural productivity and improve the efficiency of managing fields and crops.

Therefore, ELM presents a promising alternative for early CHD diagnosis.</em></p> Marwan Kosasih, Sahrul Ramadhani, Arni Susanti Ndruru, Reihan Renaldi, Muhamad Rahmat Fadila Copyright (c) 2024 https://journal.mediapublikasi.id/index.php/oktal/article/view/4682 Fri, 15 Nov 2024 00:00:00 +0000 ANALISIS STATISTIK DAN PROBABILITAS MASA DINAS KEPALA SEKOLAH DAN GURU DI WILAYAH KALIMANTAN MENGGUNAKAN METODE KAJIAN KEPUSTAKAAN https://journal.mediapublikasi.id/index.php/oktal/article/view/4643 <p><em>This research analyzes the service periods of school principals and teachers in four provinces in Kalimantan (Central Kalimantan, South Kalimantan, West Kalimantan, and North Kalimantan) to understand patterns and trends in the service periods of teaching staff. Years of service are an important indicator reflecting stability and continuity in the education system. Using a literature review and statistical analysis approach, this research examines the distribution of service periods through calculating frequency, mean value and cumulative frequency, and presents the results in the form of a histogram, polygon and ogive. The results show that the average length of service experience varies by province, from 7.7 to 12.8 years. The conclusions of this research suggest the importance of periodically evaluating service policy to ensure a balance between continuity and innovation in educational leadership, in order to support improving the quality of education in the Kalimantan region.</em></p> Faslih Fauji, Buna Rizal Nur Rohman, Daffa Tri Ananta, Muhamad Fazri Arizki Copyright (c) 2024 Faslih Fauji, Buna Rizal Nur Rohman, Daffa Tri Ananta, Muhamad Fazri Arizki https://journal.mediapublikasi.id/index.php/oktal/article/view/4643 Fri, 15 Nov 2024 00:00:00 +0000 Kondisi Tenaga Pendidik di Indonesia Timur: Keterkaitan Jumlah Guru Menurut Kelompok Umur di Maluku, Maluku Utara, Bengkulu, dan Papua https://journal.mediapublikasi.id/index.php/oktal/article/view/4658 <p><em>This journal focuses on the condition of the teaching workforce in Eastern Indonesia, particularly in </em><em>the provinces of Maluku, North Maluku, Bengkulu and Papua.

The results show an imbalance between the number of teachers and principals, with </em><em>the majority of teachers over 50 years old and less than 30% of teachers under 30 years old. In addition, remote </em><em>areas have difficulty in attracting qualified educators. To address these issues, we recommend providing </em><em>incentives for teachers who teach in remote areas, continuous training programs, collaboration between the </em><em>government and educational institutions, and improved access to educational resources. With these measures, </em><em>it is hoped that the quality of education in Eastern Indonesia can be significantly improved.</em></p> Muhammad Rifaldi Akbar, Gentra Ramadhan, Haykal Aiman Rayyan, Pandu Erlangga Copyright (c) 2024 Muhammad Rifaldi Akbar, Gentra Ramadhan, Haykal Aiman Rayyan, Pandu Erlangga https://journal.mediapublikasi.id/index.php/oktal/article/view/4658 Fri, 15 Nov 2024 00:00:00 +0000 IMPLIKASI STRUKTUR USIA TENAGA PENDIDIK TERHADAP KUALITAS PENDIDIKAN: STUDI KASUS DI PROVINSI BANTEN, DKI JAKARTA, JAWA TENGAH, DAN SUMATERA SELATAN https://journal.mediapublikasi.id/index.php/oktal/article/view/4687 <p><em>This study examines the effect of the age structure of the teaching force on education quality in four provinces in Indonesia. Quantitative data for 2023/2024 was analyzed to find the relationship between the age of the teaching force and education quality indicators, such as average national exam scores and graduation rates. The results show that a balance between young and senior educators contributes positively to improving education quality. Younger educators are usually quicker to adapt to technology while senior educators have more extensive teaching experience. This study recommends the need for policies that support the professional development of educators according to their age and current educational needs.</em></p> Humaidah, Rolen Hardi Irawan Zai, Bayu Samudra, Naufal Dhika Alriansyah, Julia Postelia Wea Buro Copyright (c) 2024 Humaidah, Rolen Hardi Irawan Zai, Bayu Samudra, Naufal Dhika Alriansyah, Julia Postelia Wea Buro https://journal.mediapublikasi.id/index.php/oktal/article/view/4687 Fri, 15 Nov 2024 00:00:00 +0000 Implikasi Divergensi Usia Pengajar terhadap Tingkat Penyelesaian pendidikan di Sulawesi Selatan, Utara, Tenggara, Selatan tahun 2023 https://journal.mediapublikasi.id/index.php/oktal/article/view/4691 <p><em>This research and journal aims to analyze the implications of teacher age divergence on education completion rates in South, North, Central, and Southeast Sulawesi Provinces using education completion data from 2023.
