Abstract

Buah maja (Aegle marmelos) masih diangap oleh masyarakat sebagai tanaman yang tidak memiliki manfaat. Padahal, buah yang memiliki nama lain “Bernuk” ini memiliki kandungan kimia diantaranya : saponin, flavonoid, dan tanin. Kandungan flovonoid inilah yang dapat menyebabkan kelayuan pada saraf serta kerusakan pada spirakel yang menyebabkan kematian pada serangga.Para Petani di Kabupaten Pringsewu banyak yang mengeluh karena lahan persawahannya diserang oleh Organisme Pengganggu Tanaman (OPT), salah satunya yaitu hama wereng. Penelitian ini bertujuan membuat eksktrak buah maja dengan konsentrasi 10%, 20%, dan 30% untuk diuji efektivitasnya sebagai insektisida nabati hama wereng dan mengetahui efek samping yang ditimbulkan pada tanaman padi. Insektisida nabati merupakan salah satu alternatif yang dapat digunakan untuk mengendalikan OPT, karena insektisida ini mudah terurai dan tidak merusak lingkungan. Proses pembuatan ekstrak buah maja menggunakan bahan berupa 1 kg daging buah maja, 100 gram gula merah kemudian difermentasi selama 3 hari. Penelitian ini menggunakan rancangan acak lengkap (RAL) faktorial yang terdiri dari tiga perlakuan konsentrasi (10%, 20%, 30%), tiga metode semprot, dan tiga waktu pengamatan (12 jam, 24 jam, 48 jam).Hasil penelitian menunjukkan bahwa ekstrak buah maja mempunyai efektifivitas sebagai insektisida nabati terhadap hama wereng. Konsentrasi ekstrak buah maja 30% dengan metode semprot serangga dalam waktu 24 jam adalah metodepaling efektif mematikan 53,3% hama wereng. Efek samping yang ditimbulkan terhadap tanaman padi tersebut ternyata tanaman padi menjadi lebih subur dan diharapkan dapat meningkatkan hasil panen padi.

Abstract

Sunlight plays an important role in the photosynthesis process of orchid plants for optimal growth. Cymbidium orchid plants, for example, require a range of sunlight intensity between 3500 lux to 4000 lux (B.V., 2023). When sunlight intensity is low, the photosynthesis process will inhibit orchid plant growth and flower formation (Sudarso et al., 2020). Therefore, it is important to ensure proper light intensity so that orchid plants can grow well. Based on these problems, researchers created a monitoring system and light intensity control system in the smart garden for orchid plants. The device used is an IoT-based ESP32 microcontroller, allowing users to monitor conditions anytime and anywhere via an internet connection. The light sensor used is BH1750 to monitor the intensity of sunlight in the orchid plant area. Blynk is used as an interface to connect the smartphone and the installed hardware. Through Blynk, IoT system developer can control ESP32 in real-time through internet connection. This automation system will work automatically to control the roof and lights based on the input parameters. This research successfully developed the BH1750 sensor application to automate light intensity on orchid plants using ESP32, with monitoring through the Blynk application. Based on the test results, the average accuracy is 99.11%, the average precision is 99.26%, and the average error is 0.15%. Keywords : Blynk, Sunlight, ESP32, IoT, BH1750 Sensor

Abstract

Pada proses pertumbuhan dan perkembangan tanaman dibutuhkan kelembaban tanah yang optimal. Jika tanah kelebihan kadar air akan menyebabkan pembusukan akar, sedangkan jika kekurangan kadar air tanaman tidak dapat berbunga mengalami dehidrasi. Salah satu tanaman yang memerlukan kelembaban tanah yang optimal yaitu tanaman anggrek Cymbidium. Menurut balai penelitian tanaman hias, anggrek dapat tumbuh dengan baik, jika kelembaban tanah berkisar antara 60%-80%. Oleh karena itu, penelitian ini dilakukan untuk merancang bangun otomasi kelembaban tanah untuk tanaman anggrek Cymbidium menggunakan sensor capacitive soil moisture SKU:SEN0193 untuk mendeteksi kelembaban tanah, nodeMCU ESP32 sebagai mikrokontroler berbasis IoT, pompa air mini dc 12 volt sebagai aktuator penyiraman tanaman dan aplikasi blynk untuk memonitoring kelembaban tanah dari jarak jauh. Metode perancangan perangkat keras dan perangkat lunak berhasil dilakukan berjalan sesuai dengan program yang telah dibuat, dibuktikan pada pengujian kinerja alat pompa hidup jika kelembaban tanah <60% dan mati jika kelembaban tanah >80%. Penelitian ini berhasil mengembangkan rancang bangun otomasi kelembaban tanah dengan memperoleh hasil pengujian alat menggunakan sensor capacitive soil moisture SKU:SEN0193 yang memenuhi standar validitas instrument dengan nilai rata-rata akurasi 98,76%, presisi 99,22%, dan error sebesar 0,45 % serta aplikasi blynk dapat menampilkan nlai output secara realtime.

Abstract

Air humidity is one of the important indicators in supporting the growth and development of plants. Mismatched humidity levels with plant needs can hinder their growth and cause root and stem rot. One type of plant that requires a certain humidity level is the Cymbidium orchid, which ideally needs air humidity between 60% and 80%. However, the fulfillment of this humidity requirement is generally still done manually, requiring time and human labor. To address this issue, an air humidity automation system is needed that can be monitored remotely to ensure the needs of the plants are met optimally. This study aims to design an Internet of Things (IoT) based air humidity automation system using the NodeMCU ESP32 microcontroller as the main control unit programmed through Arduino IDE software. This system has a BME280 sensor as a humidity detector and a mist maker as an actuator that produces cool mist to maintain humidity in the Cymbidium orchid planting space. The system monitoring is done remotely via the Blynk IoT application on smartphones. The research results show that this system successfully implemented the BME280 sensor in air humidity automation, with an average precision value of 98.91%, an accuracy of 98.98%, and an error rate of 0.076%.

Abstract

The growth and development process of cymbidium orchids requires a soil pH of around 5.5–6.5. Otherwise, it will cause low nutrient absorption, resulting in yellow leaves and slow growth, while too high a pH can cause the plant's roots to die. Therefore, this study developed an IoT-based ESP32 soil pH automation design to maintain soil pH stability and reduce orchid growth and development failures due to unstable soil pH. The IoT-based ESP32 soil pH automation design allows remote monitoring of soil pH conditions via a smartphone that has downloaded the Blynk application. The soil pH automation design consists of an SKJ-001 soil pH sensor to measure soil pH, an HC-SR04 ultrasonic sensor to measure solution height, and a 5 VDC pump to circulate NaOH and HCl solutions to stabilize pH. This soil pH automation system has been tested on ten soil samples with an average accuracy of 98.606%, an average precision of 99.192%, and an average error of 0.581%. Based on these results, it can be concluded that the IoT-based ESP32 soil pH automation system is effective and reliable in maintaining soil pH stability, thereby supporting optimal growth and development of cymbidium orchids.
