Pendekatan Logika Fuzzy dan ON/OFF pada Pengontrolan Suhu dan Kelembapan Plant Factory terhadap Pertumbuhan Vegetatif dan Hasil Panen Tanaman Pak Choy (Brassica chinensis L.)
Fuzzy Logic and ON/OFF Approaches to Temperature and Humidity Control of Factory Plants on Vegetative Growth and Yields of Pak Choy (Brassica chinensis L.)
Main Article Content
Sayur pak choy (Brassica chinensis L.) dibudidayakan pertama kali di negara China dan lebih tepatnya sebelum abad ke-5. Kondisi lingkungan mikro yang ideal untuk budidaya tanaman pak choy adalah suhu di range 15°C - 32°C, kelembapan bernilai 60% - 80% dan kebutuhan cahaya matahari selama 8 jam/hari. Plant factory adalah teknologi budidaya tanaman dengan kondisi lingkungan mikro terkontrol sesuai dengan kebutuhan optimal pertumbuhan tanaman. Penelitian terkait plant factory di dunia mayoritas berasal dari negara-negara maju dunia. Dengan alasan di atas dan ditambah besarnya potensi pasar sayuran di Indonesia khususnya, peneliti bertujuan untuk melakukan penelitian terkait plant factory untuk budidaya tanaman sayur pak choy (Brassica chinensis L.). Parameter yang dianalisa antara lain: tinggi tanaman, lebar daun, jumlah daun, bobot segar tajuk, bobot segar akar, bobot total, bobot kering total, luas daun dan indeks luas daun, klorofil daun, penyekapan cahaya dan ketebalan daun serta indeks sampah. Data hasil pertumbuhan vegatatif dan panen pak choy adalah berbasis logika fuzzy adalah sebagai berikut: tinggi tanaman 20,25 cm; lebar daun tanaman 6,95 cm; jumlah daun tanaman 12,25 buah; bobot segar tajuk 93,62 g; bobot segar akar 11,4 g; bobot total 105,02 gr; bobot kering total 18,57 gr; luas daun 25,41; indeks luas daun 0,039; klorofil daun 59,94; penyekapan cahaya 43,2; ketebalan daun 0,47; dan indeks sampah 0,89.
