Abstract

Salah satu tindakan yang dilakukan setelah panen jagung adalah pengeringan, yang dilakukan untuk mempertahankan kualitas jagung dan memperpanjang masa penyimpanan. Karena jagung tidak terpengaruh oleh cuaca, pengering mekanis vertikal adalah cara terbaik untuk mengeringkannya. Untuk memperbaiki kekurangan dari rancangan alat sebelumnya, modifikasi dilakukan. Kekurangan ini termasuk kehilangan energi yang signifikan karena bahan yang digunakan memiliki rongga dan kurang praktis karena tidak ada tempat untuk mengeluarkan jagung. Tujuan dari penelitian ini adalah untuk menciptakan dan mengubah perangkat pengering vertikal untuk proses pengerigan. Selain itu, untuk mengetahui seberapa efektif dan efisien pengeringan jagung menggunakan pengering mekanis dan pengering konvensional. Metode yang digunakan termasuk perubahan pada rancangan fungsional dan struktural unit kerangka, ruang pengering, ruang pemanas, alat kontrol suhu, dan sistem blower. Pada ruang pengering, material yang digunakan diubah untuk mengurangi kehilangan energi, dan ruang pengeluaran jagung ditambahkan untuk kinerja alat yang lebih efisien. Parameter yang diuji termasuk waktu pengeringan, kadar air awal dan akhir, kualitas jagung pipil setelah pengeringan, dan analisis efisiensi. Hasil penelitian menunjukkan bahwa penggunaan pengering mekanis vertical dryer mampu mengurangi waktu pengeringan dibandingkan dengan metode konvensional, dengan kadar air akhir mencapai 14%+ 1%bb yang memenuhi standar penyimpanan. Selain itu, kualitas jagung pipil yang dikeringkan menggunakan vertical dryer memiliki kualitas yang lebih bagus karena terhindar dari kontaminasi debu dan factor external. Alat pengering mekanis vertical dryer merupakan alternatif yang lebih efektif dan efisien untuk pengeringan jagung pipil dibandingkan dengan metode konvensional, terutama dalam hal waktu dan kualitas hasil pengeringan.

Abstract

Research had been carried out to modify polystyrene box as fresh cabbage delivery box using dry ice as a cooling medium. The research aims were to find out the most suitable model box to maintain the freshness of the vegetables. Modified polystyrene box was made by separating the box into two compartments, one compartment for placing dry ice, and another compartment for storing the fresh cabbage. The box was modified into five types which consisted of two types of the box where the cooling medium was placed below the fresh vegetable, while for the rest, the cooling medium was placed above the vegetable. The tests were performed for 7 hours with the hourly observation that consisted of the temperature surrounding the model box, temperature inside the box, and temperature of the center of the fresh cabbage. Other conducted measurements were the weight of dry ice used during cold storage, weight loss of fresh cabbage, visual observation on the deterioration of the fresh cabbage, and energy equilibrium calculation. Placing dry ice below the fresh cabbage caused the center temperature of the fresh cabbage to far above the recommended storing temperature, 0oC, while placing the cooling medium above the vegetable gave a negative impact on the vegetable where the center temperature of the fresh cabbage was below 0oC for the two types of model boxes, except for the fifth type box where dry ice was placed in a basin made of zink plate. Based on energy calculation it was revealed that almost more than 75% of cooling energy was used to overcome the surrounding cooling load. It was found that the most suitable model box for storing the fresh cabbage was the fifth type.

Abstract

Control systems are widely applied in agriculture, such as using microcontrollers to control humidity in greenhouses. Lack of accuracy in conditioning the humidity in indoor farming affects plant growth and productivity, especially in microgreens. The humidity of the planting media indirectly affects the air humidity through evaporation. Therefore, a system is required to control and monitor air and planting media humidity. The purpose of this study was to design and build an air humidity control system using PWM (Pulse Width Modulation) in a greenhouse equipped with a monitoring and automatic irrigation system. The system control employed Arduino UNO ATmega328P as a microcontroller connected to the DHT22 sensor as an air humidity sensor, a capacitive soil moisture sensor as a humidity sensor for the planting media, relay to control misting and irrigation pump. The microcontroller was also connected to a driver as a DC fan control with PWM control, four DC fan as airflow suppliers and dehumidifiers, and LCD 16x2 as a monitoring system. The system used the air humidity setting points for microgreens which were entered manually through coding. The result of this research was a lean-to greenhouse prototype with a DHT22 sensor with air humidity error values of DHT22(1) 3.09% and DHT22(2) 3.34%. The system successfully read and displayed data and provided output with a response time of irrigation and misting systems of 78mS and 145mS, using a delay of 2 seconds. The PWM control of the DC fan was able to reduce and maintain the air humidity within the optimum range for microgreen growth by increasing as well as decreasing the DC fans’ RPM, which was based on its duty cycle value

Abstract

Lettuce is a widely consumed vegetable in Indonesia. One method of cultivating lettuce is using hydroponics with a floating raft system, and further improvement can be achieved by applying an electromagnetic field. This study aims to determine the effect of electromagnetic field variations on lettuce growth, measured by the number of leaves, root length, fresh weight, and dry weight. A solenoid was used as the source of the electromagnetic field, with three treatments: T0 without an electromagnetic field, T1 with 0.00027 Tesla, and T2 with 0.00047 Tesla. The research employed a completely randomized design with three treatments and five replications. Data were analyzed using ANOVA and LSD 5% test. The results showed that the application of an electromagnetic field significantly affected all observed variables, with the T2 treatment producing the best results: an average of 11.7 leaves, root length of 35.8 cm, fresh weight of 114.53 grams, and dry weight of 12.56 grams.
