Abstract

Conventional crop cultivation systems experience several limitations, including the season, the length of day that does not match the needs of the plant, the availability of water and the narrowing of agricultural land due to population growth. Indoor farming can be a solution to overcome limitations in conventional cultivation. Indoor farming is an indoor farming system with a controllable climate, including light, temperature, evaporation and air circulation. Sunlight is the main light source in nature. Light is an electromagnetic wave that carries a form of energy. Sunlight has many functions for life on earth, one of which is as a source of energy for plants to carry out photosynthesis. Photosynthesis is a biochemical process for the formation of food substances such as carbohydrates carried out by plants. Photosynthesis takes place using chlorophyll, carbon dioxide and water and the help of sunlight energy. Sunlight consists of UV rays, visible rays and infrared rays. Visible light has a wavelength between 400 - 700 nm. Visible light is the light that plants use for photosynthesis. Chlorophyll can absorb red (600-700 nm) to blue (400-500 nm) wavelengths. The quality of sunlight is good for plant growth because it has the entire spectrum needed for photosynthesis. Artificial light from lamps that are used as a substitute for sunlight in order to support plant growth must have the quality according to plant needs. The quality of light from each source is not the same. This is the basis for conducting the study, namely comparing the quality of sunlight and artificial light sources such as lamps. Based on the studies that have been done, the color spectrum of artificial light that approaches the spectrum of sunlight is the white color spectrum. A more efficient substitute for the white color spectrum for plant photosynthesis with the pigment chlorophyll is the blue and red or growlight color combination.

Abstract

Background:The basil plant (Ocimum basilicum L.) is characterized by its mint-like aroma and fresh taste, but its cultivation is still small and agricultural land is increasingly limited. This problem can be overcome by indoor hydroponic cultivation using artificial lights. The research was carried out in Ngagel Rejo Utara No. 24, Surabaya City, East Java from October-November 2022 using artificial LED light installations in closed rooms.Method: This research is a factorial experiment which was prepared using a Split Plot Design (RPT) which consisted of two factors and was repeated three times. The first factor is the intensity of LED light (C) as the main plot which consists of 4 treatment levels, namely 1,500 lux (C1), 1,700 lux (C2), 2,000 lux (C3), 2,200 lux (C4) and the second factor is the type of planting medium ( M) as a subplot consists of 3 treatment levels, namely charcoal husk (M1), cocopeat (M2), rockwool (M3).Results: The results of the research showed that the combined treatment of light intensity of 2,200 lux and rockwool planting media was able to increase the parameters of plant height, number of leaves, wet stover weight, dry stover weight and the volume of nutrient absorption by the plants.Conclusion: The combination of 2,200 lux light intensity treatment and rockwool planting media is the best combination for the parameters of plant height, number of leaves, wet stover weight, dry stover weight and the volume of nutrient uptake of basil plants (Ocimum basilicum L.) indoor hydroponic wick system.
