Abstract

Kopi adalah salah satu minuman paling umum dan favorit yang dikonsumsi banyak orang di seluruh dunia. Proses roasting kopi memegang peranan penting dalam menentukan rasa kopi. Tahapan dalam proses roasting kopi terdiri dari pengeringan, penguningan, pecahan pertama, roast development, dan pecahan kedua. Dari kelima tahapan tersebut, proses pecahan pertama kopi merupakan awal mula terbentuknya karakteristik biji kopi. Pada tahap ini, seorang penyangrai biji kopi profesional harus memastikan suhu dan waktu yang sesuai agar biji kopi tidak hangus/gosong. Pada alat roasting kopi manual, hal ini menimbulkan ketidakonsistenan hasil roasting biji kopi karena sangat bergantung dari kemampuan dan pengalaman sang penyangrai biji kopi sedangkan pada smart coffee roaster menggunakan sensor dan control cerdas untuk mengoperasikan roaster dan mendapatkan kopi dengan konsistensi terbaik dan akurat. Makalah kali ini membahas tentang peluang dan tantangan yang diperlukan untuk membuat versi terbaik dari smart coffee roaster dari sisi system elektronik, desain, dan Artificial Intelligence (AI). Sistem elektronik terdiri dari sensor, control, dan aktuator. Desain yang Ergonomis, estetis, serta kenyamanan pengguna menjadi kunci utama yang diperlukan untuk membuat desain terbaik. Aplikasi AI mendeteksi kematangan biji kopi dan deteksi suara “retak” dengan memanfaatkan teknologi machine learning. Studi awal dilakukan dengan format audio hasil roasting dan dipisahkan antara audio yang mengandung suara retakan biji kopi dan audio yang tidak mengandung suara retakan biji kopi. Dataset audio tersebut kemudian diubah ke dalam format gambar menggunakan metode Mel-frequency cepstral coefficients (MFCC), untuk kemudian dilakukan pemodelan dengan menggunakan supervised learning convolutional neural network (CNN).

Abstract

Teknologi akan menjadi pilihan yang diandalkan pada pertanian modern untuk meningkatkan efisiensi dan produktivitas, salah satu contoh adalah penggunaan rumah tanaman (planthouse), yang digunakan untuk kegiatan budidaya tanaman, dengan tujuan untuk melindungi tanaman dari hujan, angin dan hama, serta dapat mengontrol lingkungan secara optimal [1]. Peralatan yang dipakai untuk mengatur tingkat kelembapan udara yang merupakan salah satu parameter penting selain temperatur adalah humidifier [2]. Namun ternyata humidifier konvensional yang masih banyak dipakai seringkali menghadapi kendala seperti konsumsi energi yang tinggi, distribusi uap air yang tidak merata, serta perawatan yang komplek [3][4]. Kemudian teknologi humidifier ultrasonic vibration system muncul sebagai alternatif yang lebih efisien dan efektif dalam mengontrol kelembapan [5]. Teknologi ini menggunakan prinsip getaran ultrasonik untuk menghasilkan partikel uap air yang sangat halus, sehingga distribusi kelembapan menjadi lebih merata dan hemat energi [6]. Selain itu, humidifier jenis ini memiliki keunggulan dalam hal kebisingan dan minimnya pembentukan kerak mineral. Karena penerapan teknologi ini khususnya dalam konteks pengontrol kelembapan rumah tanaman masih relatif terbatas, maka dalam penelitian ini akan dibuat sebuah purwarupa humidifier ultrasonic vibration system dengan daya sembur yang dapat diatur, sehingga dapat mengontrol kelembapan yang lebih presisi, efisiensi energi yang lebih baik, serta peningkatan produktivitas tanaman dalam lingkungan rumah tanaman.

Abstract

The greenhouse plays a pivotal role in creating an ideal environment for hydroponic cultivation. The greenhouse has utilized rainwater and basin water as a source of raw water for hydroponic farming. Presently, the water quality of Leuwi Padjadjaran basin fails to meet the standards required for hydroponics due to its turbidity, sediment content, discoloration, pH levels exceeding 7, and low dissolved oxygen (DO) concentration of 2.2 mg/l. The micro/nanobubbles (MNBs) technology stands as a viable method for water treatment owing to its capacity to bind impurities via radical OH. The application of MNBs for the treatment of basin water involves the use of a hydrodynamic cavitation MNBs generator with a dual-chamber rotating flow nozzle. The parameters evaluated in this research encompass DO concentration, MNBs stability, microbubble size, and the visual response to MNBs application. MNBs treatment was conducted with three different gases: air, oxygen, and ozone. Microbubbles were measured using the particle image velocimetry (PIV) method. The DO concentration reaches 21.6 mg/l when employing oxygen-based MNBs. On the third day post-generation, MNBs stability still maintains DO concentrations above the initial levels. Thus it can be used as hydroponic raw water.  Keywords:  DO concentration, Greenhouse, Micro/nanobubbles, Water treatment.

Abstract

Hydroponic model SWU-01 is a new hydroponic system innovation that regulates watering automatically and independently by utilizing gravity and Archimedes' law. Dissolved oxygen concentration in SWU-01 is only around 3-4.2 mg/L. DO values can be increased by applying nanobubble technology. Ultrafine bubble or nanobubble is a gas bubble in a liquid that has a diameter of <200 nm. The purpose of this study was to determine the effect of nanobubble on dissolved oxygen concentration and growth of lettuce plants cultivated with SWU-01 hydroponics. The experiment used a one-factor randomized complete block design, namely intermittent administration of nanobubble for 15 min every 3 day (P1) and 7 days (P2), and without nanobubble (P0l). The results obtained based on the ANOVA test at the 5% level with the Least Significant Difference (LSD) follow-up test, namely the parameters of fresh weight and number of leaves of lettuce P1 significantly different from P0 and P2, and no significant differences were found in root length, canopy width, and plant height. The P1 treatment is more effective in increasing dissolved oxygen concentration, leaf count, and fresh weight of lettuce produced in lettuce cultivation using the SWU-01 hydroponic system. Keywords: Dissolved oxygen, Hydroponics, Lettuce, Nanobubbles, Plant growth.

Abstract

The three priority issues faced by the Cikandang Agro Farmers Group are 1) the flow of nutrient solution is not smooth due to clogged nozzle holes and the insoluble nutrient solids; 2) the misting flow of the nutrient solution is uneven due to leaks at several points in the nutrient solution distribution pipes; and 3) not all root zones of the plants are reached by the nutrient spray due to the nutrient solution spray not being in the form of fog. The objectives of the activity are 1) to design and to construct a system device for preparing and atomizing nutrient solutions for the production of potato seeds in an aeroponics system; and 2) improve the performance of nutrient solution preparation and atomization system devices for potato seed production aeroponics system. The implementation of activities consists of program socialization, training/technical guidance, application of technology, as well as monitoring and evaluation. The substance of the activity consists of problem and need analysis, design and assembly, as well as operation and performance tests. Success indicators were observed through pre-test and post-test which included domains of the cognitive and psychomotor of participants in mastering the technology of preparation and atomization of nutrient solutions for the production of potato seeds in the aeroponics system. Based on the evaluation through pre-test and post-test, there was an increase in the cognitive domain by 80% and psychomotor domain by 70% of participants in mastering the technological aspects of preparation and atomization of nutrient solutions for the production of potato seeds of the aeroponics system. Technical improvements to the equipment of the nutrient solution preparation and fog system produce a smooth flow of nutrient solution, and the nutrient solution spray is no longer in the form of mist but in the form of a uniform fog and is able to reach the plant root zone.
