Abstract

Oyster mushroom is one of the favorite horticultural commodities consumed by Indonesian people. In the cultivation of oyster mushrooms, there are many obstacles faced by farmers, including the difficulty in maintaining the temperature and humidity of the kumbung room so that to maintain the stability of temperature and humidity, farmers must always check and do regular watering. With these problems, a temperature and humidity monitoring and control system is needed to maintain the stability of temperature and humidity in oyster mushroom cultivation by automatically watering and heating the room temperature of the kumbung. The design of the system was designed based on the results of interviews with oyster mushroom farmers regarding the constraints faced, then proceed with the design and manufacture of hardware and software for an IoT-based oyster mushroom kumbung watering and heating system. The result of this research is that the system can respond to changes in temperature and humidity conditions in the kumbung room by automatically watering and heating the kumbung room. To return to the setpoint temperature value (25oC-28oC), it is necessary to heat the kumbung room with an average duration of heating of 383 seconds, and to return to the setpoint humidity value (75%-90%), it is necessary to water the kumbung room with an average watering time of 115 seconds.

Abstract

The church is a place of worship for Christians. Its presence is expected to provide both physical and spiritual tranquility. To achieve this, church facilities must strive to offer comfort to their users, such as the congregation's prayer benches. However, some of these prayer benches fail to provide sufficient comfort because, historically, church bench designs are relics from the past, dating back to when the church was first established, and did not take comfort into account during their design. This is also the case at the Catholic Church of St. John the Evangelist in Kudus, where the congregation's prayer benches are still the original design from when the church was founded. As a result, there have been several complaints about the discomfort from users. The method used in this study employs an ergonomic approach to redesign the congregation's prayer benches at the Catholic Church of St. John the Evangelist in Kudus. Anthropometric data used to design the prayer benches were gathered from Javanese and Chinese ethnic groups, both male and female. The results of the study yielded a design for the prayer benches at the Catholic Church of St. John the Evangelist in Kudus, with the following dimensions: prayer bench length = 334.96 cm; bench width = 43.80 cm; bench height = 39.2 cm; shoulder rest height = 47.53 cm; and prayer handrest height = 60.17 cm. Another outcome of this study is the implication for the church congregation, which is an increased perception of comfort in the design of the prayer benches through the ergonomic approach.

Abstract

Banjir merupakan permasalahan yang terjadi akibat dari volume air yang berlebih pada sungai yang dipengaruhi oleh aktifitas manusia yang tidak ramah terhadap lingkungan. Desa Setrokalangan merupakan salah satu desa di kecamatan kaliwungu kabupaten Kudus. Desa ini menjadi langganan banjir disetiap musim penghujan datang. menurut informasi dari beberapa sumber pada akhir tahun 2022, desa Setrokalanganini terendam banjir hampir satu meter yang disebabkan tingginya intensitas hujan yang mengguyur wilayah kabupaten Kudus dan meluapnya sungai wulan. Sebagai wilayah rawan bencana banjir perlu kiranya dilakukan mitigasi bencana sebagai upaya untuk meminimalisir dampak dari banjir yang dialami. Adapun metode yang digunakan adalah dengan menerapkan sistem peringatan dini banjir menggunakan teknologi Internet Of Things pada daerah aliran sungai untuk meningkatkan kesiagaan masyarakat dalam menanggulangi banjir disamping meningkatkan kesadaran masyarakat akan pentingnya menjaga kebersihan lingkungan sungai. Dari hasil penerapan teknologi peringatan dini banjir ini warga masyarakat disekitar daerah aliran sungai atau daerah terdampak lainnya menjadi lebih waspada dan meningkatkan kesiagaan dalam menanggulangi banjir, sehingga meminimalisir tingkat kerugian materi yang diakibatkan banjir.

Abstract

Anak ayam membutuhkan perhatian ekstra, terutama untuk suhu kandang, ketersediaan makanan, dan air minum. Suhu ideal untuk mereka adalah antara 30°C hingga 35°C, walaupun suhu luar bisa mempengaruhi suhu di dalam kandang. Kenyamanan anak ayam ditentukan oleh panas, aliran udara, dan tingkat kelembaban di kandang, yang harus disesuaikan dengan kemampuannya beradaptasi. Suhu yang terlalu panas sangat berbahaya karena dapat mengganggu kondisi tubuh, kesehatan, dan pertumbuhan anak ayam, bahkan bisa berakibat fatal hingga menyebabkan kematian. Berdasarkan kondisi ini maka diperlukan sistem monitoring untuk memantau suhu dan memastikan ketersediaan pakan anak ayam. Metode penelitian yang digunakan adalah Research and Development (R&D), dengan tujuan membuat sistem monitoring suhu dan ketersediaan pakan anak ayam berbasis Internet of Things (IoT). Tahapan pembuatan alat diawali dengan studi literatur, merancang dan membuat desain monitoring suhu dan pakan ayam dan terakhir adalah tahap uji coba alat. Sistem pengontrol suhu bekerja dengan baik menggunakan sensor DHT22, yang mampu menjaga suhu kandang pada kisaran 30°C hingga 33°C, dengan tingkat akurasi pengukuran mencapai 96,47%. Sedangkan untuk deteksi ketersediaan pakan ayam menggunakan sensor ultrasonic. Sistem pemberi pakan dan air minum dapat dimonitor secara real-time melalui aplikasi Blynk, yang responsif dalam memberikan notifikasi terkait ketersediaan pakan dan air.

Abstract

Kalibrasi sensor merupakan langkah penting dalam proses pengukuran besaran fisis untuk memastikan hasil yang diberikan oleh alat ukur atau sensor akurat dan memenuhi standar. Keakuratan dan ketepatan dalam penelitian ini bergantung pada peralatan dan metode yang digunakan untuk mengkalibrasi sensor ultrasonik JSN-SR04T, yang berperan sebagai pengukur jarak pada sistem peringatan dini banjir. Metode yang diterapkan dalam penelitian ini adalah pendekatan regresi linier yang diprogramkan pada Arduino Uno, sehingga data pengukuran dari sensor JSN-SR04T dapat dibaca melalui serial monitor Arduino IDE. Data yang dihasilkan sensor ultrasonik JSN-SR04T awalnya belum cukup akurat dan presisi; sebelum dikalibrasi, tingkat akurasinya mencapai 96,6% dengan error 3,40%, namun setelah kalibrasi menggunakan regresi linier, akurasinya meningkat menjadi 99,7% dengan error yang turun menjadi 0,3%.

Abstract

Manual recording of water meters in the Community-Based Drinking Water and Sanitation Program (PAMSIMAS) is still vulnerable to human error, reporting delays, and operational inefficiencies. This study proposes a smartphone-based Automated Meter Reader (AMR) system that utilizes Optical Character Recognition (OCR) as a low-cost digital solution for rural environments. The system uses a smartphone camera to capture an analog water meter image and processes it through a computer vision pipeline that includes grayscale conversion, bilateral filtering, Canny edge detection, contour-based segmentation, and a full-image OCR fallback mechanism. An experimental evaluation was conducted on 120 analog water meter images with variations in lighting, capture angle, blur level, and meter surface conditions. Digit extraction was performed using Google Vision OCR (online) and Tesseract OCR (offline). The OCR accuracy was calculated based on the compatibility of the digit value of the recognition result with the ground truth value and complemented by confidence score analysis. The test results showed an average OCR accuracy of 91%, a confidence score of 0.87, and an average processing time of 1.27 s per image. Although the system showed stable performance in most test scenarios, the accuracy declined in strong glare conditions and with faulty meters, indicating the limitations of the contour-based segmentation approach. Overall, this smartphone-based AMR system has proven to be feasible and practical for supporting the digitization of community-based water management, with the potential for further development through deep learning-based segmentation.
