Abstract

Amorphophallus has 176 species spread throughout the world, 25 of which are found in Indonesia. Of the 25 species found in Indonesia, 8 of them are endemic to Sumatra. One type of Amorphophallus found on the island of Sumatra is Amorphophallus titanum, whose survival in its natural habitat is threatened by deforestation and forest degradation. As an endemic plant, A. titanum is also more vulnerable to anthropogenic threats and environmental change, and therefore faces a greater risk of extinction than more widespread species. To prevent species extinction and as a form of biodiversity conservation, information is needed that presents the population status of A. titanum in its natural habitat. This article aims to provide information about the population of corpse flowers (Amorphophallus titanum Becc) in Sumatra. The research method used is a literature review. Data was obtained from journals and articles published from 2005 to 2023. Based on research conducted, it is known that A. titanum is often found in Bengkulu, Lampung, Jambi, North Sumatra and West Sumatra. The highest population of A. titanum is in Muara Hemat Village, South Kerinci Resort, Kerinci Seblat National Park, Jambi, with a total of 83 individuals. In Bengkulu, A. titanum is found in several locations; in KHDTK (Forest Areas with Special Purposes) as many as 64 individuals. At Ketapang Water, Jufi Hill and Datar Lebar Waterfall there were 56 individuals. In the Mount IV Kepahiang Nature Reserve there are 56 individuals. In Tebat Monok, Air Selimang and Palak Siring the number is 52 individuals. Meanwhile in North Sumatra, specifically in the Sibolangit Nature Reserve, Sibolangit Nature Reserve, Dolok Sipirok Nature Reserve, and Namo Suro Baru Village, 32 individuals were found. In Palupuah, Agam Regency, and South Solok, West Sumatra, there are 24 individuals, and also in the Liwa Botanical Gardens, Lampung, there are 4 individuals.

Abstract

Pakcoy (Brassica rapa L.) is a widely cultivated leafy vegetable with high economic value. Limited agricultural land and the need for more efficient cultivation systems encourage the use of hydroponic technology, particularly through the use of pH and TDS sensors to optimize nutrient management. This study aims to compare the growth of pakcoy plants using the Deep Flow Technique (DFT) hydroponic system with pH and TDS sensors and without sensors. The study used a Completely Randomized Design (CRD) with two treatments: 50% AB mix + 50% POC with sensors, and 50% AB mix + 50% POC without sensors, with nine replications. The parameters observed included plant height, number of leaves, leaf area, fresh weight, and dry weight. Data were analyzed using an unpaired t-test at a significance level of 5%. The results showed that the use of pH and TDS sensors significantly affected all growth parameters. The treatment with sensors resulted in higher average values, namely plant height of 25.1 cm, number of leaves of 17.3, leaf area of 514.6 cm², fresh weight of 236.28 g, and dry weight of 30.7 g compared to the treatment without sensors. Automatic nutrient monitoring creates stable solution conditions, thereby increasing nutrient absorption efficiency and plant biomass accumulation. This study concluded that the use of pH and TDS sensors is effective in optimizing and increasing the productivity of bok choy plants in hydroponic systems. It is recommended that IoT-based monitoring technology be applied more widely to improve cultivation efficiency, reduce costs, and support sustainable agriculture.
