Abstract

The increase in demand for mustard greens requires an increase in production by using superior varieties and improving cultivation techniques, one of which is using an aeroponic system. Aeroponics is a hydroponic technique where the plants are suspended in the air. Aeroponic systems can now be combined with IoT (Internet of Things) devices called smart aeropoics systems. The purpose of this research is to find out the effect of different varieties of mustard greens and nutrient concentrations on the growth and yield of mustard greens with a smart aeroponics system. The research was conducted in the UG Technopark Smart Farming Greenhouse from May to July 2023 using a Randomized Complete Group Design Nested Design consisting of two factors, namely factor I (main plot) is the concentration of AB Mix nutrients consisting of two levels, namely 1000 ppm and 1500 ppm. Factor II (subplots) is the type of mustard green variety consisting of four levels, namely Shinta F1, SA 764 (Princess), Tosakan and CS1443 (Serena). The results showed that different varieties had a significant effect on the growth of mustard green plants in the parameters of plant height, number of leaves, root length and leaf area. Different nutrient concentrations significantly affect the growth and yield of mustard greens in the parameters of number of leaves, root length, crown wet weight, root wet weight, crown dry weight and root dry weight.Keywords: cultivation, internet of things, sensors, smart farming, nutrients

Abstract

The miana plant is an ornamental plant that has potential as a medicinal ingredient. The part of the miana plant that is used as an ornamental or medicinal plant is the leaves. Efforts to increase the growth and yield of miana plants include fertilization. This research aims to analyze the effect of different organic fertilizers on the growth and yield of miana through the application of automated drip irrigation technology. The design used in this research was a single-factor Randomized Complete Group Design, namely organic fertilizer with five levels and five replications each. The treatment levels in this study were without fertilizer (P0), cow manure (P1), goat manure (P2), chicken manure (P3), guano fertilizer (P4), and quail manure (P5). The results of the research show that differences in organic fertilizer affect miana growth through the application of automated drip irrigation technology which can be seen in the parameters of plant height, number of leaves, and number of branches. Cow manure gave the highest average value and was able to increase miana growth most dominantly at the start to the end of the observation week compared to other treatments. Meanwhile, the parameters include leaf area, stem dry weight, leaf dry weight, total biomass, and total flavonoids. Goat manure gave the highest average value and increased miana yield in the leaf area, stem dry weight, and total biomass parameters, while cow manure gave the highest average value and increased miana yield in the leaf dry weight parameter. Apart from that, quail manure gave the highest average value and increased the yield of miana on the total flavonoid parameter.

Abstract

Selada merupakan dalam komoditi hortikultura unggul yang mengandung gizi dan mineral yang tinggi. Tujuan studi ini adalah untuk mengevaluasi pemberian pupuk organik cair (POC) dan pupuk NPK terhadap parameter pertumbuhan dan produksi selada keriting. Percobaan ini menggunakan rancangan kelompok lengkap teracak (RKLT) faktorialmenggunakan dua faktor, yaitu konsentrasi POC (0, 2, 4, dan 6 ml L-1) dan dosis NPK (0, 3, 6, serta 9 g L-1). Percobaan ini direplikasi sebanyak tiga kali, dengan empat sampel tanaman diambil dari setiap petak percobaan. Analisis statistik menunjukkan tidak ada interaksi signifikan antara aplikasi POC dan pupuk NPK terhadap pertumbuhan selada. Namun, secara terpisah, baik POC maupun pupuk NPK memberikan pengaruh nyata pada beberapa parameter pertumbuhan. Secara spesifik, pupuk NPK secara signifikan memengaruhi jumlah daun dan tinggi tanaman, sedangkan POC memberikan pengaruh secara signifikan pada parameter diameter batang dan jumlah daun. Berdasarkan hasil ini, dosis terbaik adalah 9 g L-1 untuk pupuk NPK dan 6 mL L-1 untuk POC.

Abstract

Unsur hara mikro essensial dalam tanah sangat penting untuk pertumbuhan tanaman. Unsur hara mikro dibutuhkan dalam jumlah sedikit sehingga harus terukur secara presisi di dalam tanah agar tidak terjadi defisiensi ataupun toksisitas pada tanaman. Dalam perkembangan dunia pertanian yang cerdas dan presisi maka sistem deteksi hara menjadi salah satu teknologi yang tepat guna untuk mengatasi permasalahan analisis di laboratorium yang mahal, lama dan tidak spesifik lokasi. Tujuan dari penelitian yang dilakukan yaitu mendapatkan model optimasi untuk sistem deteksi unsur hara mikro essensial dalam tanah berbasis potensial redoks. Tahapan penelitian yang dilakukan yaitu merancang hardware berupa prototipe alat deteksi unsur hara mikro dan perancangan software. Selanjutnya uji kalibrasi dan validasi alat dilakukan dalam beberapa tahap, yaitu uji kalibrasi dan validasi alat menggunakan alat ukur portabel pH dan EC meter. Aproksimasi dari uji kalibrasi dan validasi digunakan untuk source code pada sistem deteksi hara. Model aproksimasi yang digunakan pada prototipe ini adalah persamaan regresi kubik. Dari model aproksimasi yang digunakan maka dapat menghasilkan prototipe sistem deteksi unsur hara mikro essensial dengan persentase akurasi yang tinggi pada indikator pH yaitu sebesar 95.63% sedangkan pada indikator EC memiliki akurasi sebesar 79.64%. Berdasarkan pendekatan nilai Eh–pH maka didapatkan bahwa pada 7 lokasi pengamatan menunjukkan terdapat 4 titik lokasi yang unsur Fe berada dalam bentuk Fe2+ dan terdapat 3 titik lokasi pengamatan yang unsur Fe berada dalam bentuk Fe(OH)3. Pada diagram pH-Eh untuk unsur hara mikro Mn menunjukkan bahwa unsur Mn tersedia berada dalam bentuk Mn2+.
