Abstract

Kale memerlukan pencahayaan minimal 14-16 jam setiap hari untuk pertumbuhan yang optimal, sehingga cahaya dapat memengaruhi fase vegetatif dan kualitas keseluruhan tanaman kale. Tujuan penelitian ini adalah untuk mendapatkan spektrum cahaya dan lama penyinaran yang memberikan hasil optimal terhadap pertumbuhan dan hasil produksi dua varietas tanaman kale. Penelitian dilakukan di Greenhouse UG Technopark pada bulan April-Juni 2024 menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) Pola Tersarang (Nested Design) yang terdiri dari dua faktor yaitu faktor I (petak utama) adalah spektrum cahaya dan lama penyinaran (L) terdiri dari 10 taraf. Faktor II (anak Petak) yang tersarang pada spektrum cahaya dan lama penyinaran adalah jenis varietas kale (V) terdiri dari 2 taraf. Perlakuan diulang sebanyak 4 ulangan. Parameter yang diamati adalah tinggi tanaman (cm), lebar daun (cm), jumlah daun (helai), laju pertumbuhan tinggi tanaman (cm/hari), diameter batang (cm), bobot segar tanaman (g), dan bobot kering tanaman (g). Data yang diperoleh dianalisis menggunakan analisis sidik ragam (ANOVA) dan selanjutnya perlakuan yang pengaruhnya nyata akan dianalisis uji lanjut dengan uji Duncan’s Multiple Range Test (DMRT) pada taraf a = 5%. Hasil penelitian menunjukkan bahwa perlakuan spektrum cahaya dan lama penyinaran berpengaruh nyata terhadap tinggi tanaman, lebar daun, jumlah daun, bobot segar tanaman, dan bobot kering tanaman, sedangkan perbedaan varietas berpengaruh nyata terhadap tinggi tanaman, lebar daun, laju pertumbuhan tinggi tanaman, dan diameter batang.

Abstract

The high demand for water spinach demands increased production through more efficient cultivation techniques. One important factor that affects plant growth and production is lighting. This study aims to optimize the growth and production of two varieties of water spinach by adding LED lights with a certain light spectrum and duration. The study used a Nested Complete Randomized Block Design (RBD) consisting of two factors. The first factor is the light spectrum (L) with 3 levels, namely the red light spectrum of the 18/6 photoperiod (L1), the blue light spectrum of the 18/6 photoperiod (L2), and the red-blue light spectrum of the 18/6 photoperiod (L3). The second factor is the variety of water spinach (V) consisting of two levels, namely the curly water spinach variety (V1) and the lacinato water spinach variety (V2). Each treatment was repeated 4 times so that there were 24 experimental units. Data analysis used ANOVA with a 5% confidence level and further testing using the Duncan test. The results showed that the growth and production of the two varieties of water spinach were more optimal with the addition of the red-blue light spectrum.

Abstract

Vegetables are agricultural products that are perishable (easily damaged), so they are susceptible to a decrease in product quality. One of the efforts to improve the quality of vegetable products is to control the quality of these products. The purpose of this study was to determine the disabled group, the factors that cause the disability and alternative efforts that can be implemented in pakcoy vegetables. This study uses the Six Sigma method to improve the stage. This research was conducted from May to July 2023 at PT. Morning vegetables. The results showed that PT Sayuran Pagi was still in the 3-sigma range with a DPMO value of 35438.48. The defect groups of pak choi vegetables at PT. Sayuran Pagi consists of 3 (three) defect groups, namely broken stems of 77.56%, yellow leaves of 17.16% and white spots of 5.28%. Factors that cause defects in morning vegetables are human factors, methods, machines and the environment. Alternative efforts that can be implemented include: Monitoring and guiding during harvesting, making checklists for checking nutrition, calibrating TDS tools regularly, providing information on the importance of closing doors, making reminder boards in front of green house doors, implement personal hygiene SOPs, provide counseling about pests and diseases that have the potential to attack pakcoy vegetables, provide direction to partners regarding distribution, use sturdy containers, create SOPs on nutrition for pakcoy vegetables, change plant spacing between holes, carry out preventive pest and disease control with natural pesticides.
