Abstract

Melon is one of the high value crops, so it needs to be empowered. Melon growth is closely related to the state of water, soil pH, and nutrients. A mismatch in water content causes stunted growth. Melon grow well in soil with a pH of 6-7, where nutrients are easily absorbed. Human has limitations in watering, fertilising and controlling the pH of the soil manually. Therefore, a system for automatic watering, fertilisation and pH control with drip irrigation is needed. This system uses Arduino Mega2560 as a microcontroller, RTC for scheduling watering and fertiliser, pH sensor for controlling soil pH, water level sensor to measure the contents of the container with notification to Telegram. In this research, the system succeeded in watering and fertilising on schedule with 100% time accuracy, and controlling soil pH with a pH measurement accuracy of 95.57%. The system also successfully detected the solution running out and sent the notification to Telegram. The melon plants grow faster using the system than manually, with a difference in plant height of 1.029 cm on day 7. Thus it can be concluded that the system for automatic watering, fertilising, and pH control of melon plants has been successfully built.

Abstract

Offering a seamless shopping experience is essential in today's cutthroat retail environment. This paper describes a system built to tell customers about product availability in offline stores, explicitly addressing the issues related to customer reluctance and the store's physical space restrictions. The system was designed, observed, and tested to evaluate its performance. According to the findings, the system can recognize various NFC tag types at reading distances of up to 3.5 cm, 1.5 cm, and 2 cm for a card, keychain, and sticker kinds, respectively. In an average of 3.39 seconds, the server and microcontroller can establish a connection to send and receive responses from the server. Additionally, the system has a 100% success record in displaying precise product stock data based on the chosen size and color. Furthermore, the system has a 100% success rate in telling registered from unregistered NFC tags. The internet network's speed also impacts updating database data, with quicker internet connections being processed first. In conclusion, the system's effectiveness demonstrates its potential to be used in retail settings to give customers real-time product availability tracking.

Abstract

Air bersih merupakan kebutuhan pokok dalam kehidupan manusia sehari-hari, Akan tetapi tidak semua orang dapat mendapatkan air bersih. Di Indonesia masih banyak terdapat daerah yang kesulitan mendapatkan air bersih. Menurut [1], terdapat sekitar 6% luas daerah di Indonesia yang mengalami krisis air bersih pada tahun 2000, dimana jumlah ini diprediksi akan terus meningkat menjadi 9,6% di tahun 2045. Berdasarkan data ini setidaknya terdapat peningkatan daerah kritis air bersih sebanyak 0,08% setiap tahunnya. syarat agar air memenuhi standar baku mutu kesehatan adalah memiliki tingkat kekeruhan dengan nilai skala kekeruhan maksimal 25 NTU (Nephelometric Turbidity Unit) serta tingkat pH air berada pada angka 6,5-8,5. Karena hal tersebut diperlukan sistem yang dapat menjernihkan air secara otomatis dengan memberikan tawas sesuai dengan takaran yang tepat, dan juga user dapat mendapatkan notifikasi terkait kondisi air pada jarak jauh. Pada sistem untuk meningkatkan kualitas air ini maka sensor turbidity akan digunakan untuk mengukur tingkat kekeruhan yang dimiliki air dan sensor pH akan digunakan unutk mengukur tingkat pH dari air. Berdasarkan hasil dari kedua sensor ini cairan tawas akan diberikan untuk menjernihkan air dan cairan pH up/pH down diberikan untuk mengatur tingkatan pH air agar sesuai dengan standar baku kesehatan.

Abstract

The problem that occurs in Sanjai Tourism Village is inadequate internet access. Internet access is fundamental nowadays, both in daily activities and in the context of promotional activities for Tourism Villages to attract visitors. One of the aspects of assessing the Indonesian Tourism Village Award is digital creativity. To make this happen, it is necessary to have internet access that everyone can enjoy, including the community, visitors, and the Tourism Village group (Pokdarwis) in the Sanjai Tourism Village. Therefore, in Community Service activities, a Wi-Fi Coin system was designed to improve internet access in the Sanjai Tourism Village. The Wi-Fi Coin System uses coins to access the internet. In addition, the Wi-Fi Coin system can be portable for use in the desired location. The method used consists of three stages: preparation consisting of a survey and needs analysis to obtain data on community needs, especially the Sanjai Tourism Village Pokdarwis. The implementation consists of system design, testing, and implementation. System design and testing were carried out at the Unand Computer Engineering Department. Meanwhile, the implementation was done directly before the Pokdarwis team and the Village Community. Trials and equipment handover to the Sanjai Tourism Village Pokdarwis marked the activity results.

Abstract

The use of technology is fundamental in the digital era. Adjustment and transformation are essential activities to keep up with technological developments. One of the uses of technology is product marketing and promotion. Sanjai Tourism Village, located in Bukittinggi City, is one of the villages where marketing and promotion of tourism products are still carried out using conventional promotional methods such as through newspapers, radio advertisements, posters, and distribution of brochures. This method is still limited and cannot reach a broader scope. Therefore, to compete in the digital era, there needs to be a transformation of promotion and marketing of tourism products through the internet media using a website. Information about promoting and marketing tourism products can be done digitally and online using a website. The results of advertising and marketing tourism village products by utilizing the website can be spread and known to the public with a broader reach. Therefore, in the community service activities of the Unand Computer Engineering Department, the Sanjai Tourism Village website was built with a method consisting of several stages, such as coordination, surveys, design, website implementation, improvement, and submission of the website to Sanjai Tourism Village. Each stage has been carried out, and a website has been produced with features such as a homepage, profile, tourism products of various fields, news and activities, and contacts.

Abstract

In this study, a monitoring system was generated to send data about temperature, humidity, and ammonia gas from a dairy cow cage. This system also provides notifications and recommendation to the owner to carry out certain actions based on data obtained from the dairy cow cage. This system consists of three main components, namely the web server monitoring devices and an application on mobile device. Furthermore, monitoring devices consist of a microcontroller, DHT22 sensor, MQ-135, and ESP266. The microcontroller sends data to the web server and the device moves continuously to notify the state of the dairy cage. From the test results, it is known that the system can send data correctly to mobile devices and web servers. Notification of abnormal conditions is given in an average of 39 seconds.

Abstract

In Indonesian the level of diabetes mellitus in the community is very high but public awareness is very low due to many of the people WHO are phobic about blood and needles. From the above problems obtained an alternative solution by using urine as a medium to detect diabetes mellitus in a person. The tool made consists of TCS3200 color sensor, MQ-135 gas sensor, Arduino Uno microcontroller, and 16x2 LCD. The system is made using the NaÏve Bayes algorithm to be able to classify urine that has been tested Benedict including into non-diabetes or diabetes, the system is also made using multiple linear regression algorithms to be able to predict the sugar content contained in urine. In this system, the TCS3200 color sensor as an RGB color code reader and the MQ-135 gas sensor as a reading of ammonia gas levels in urine. This system can provide information about the status of urine and how much sugar levels in the body.
