Morphological Identification and Evaluation of Phytochemical Content and Antioxidant Activity of Gembili Tuber (Dioscorea esculenta L.) in Malaysia
Get PDFGembili tuber (Dioscorea esculenta L.) is a tuberous plant known for its high nutritional value and richness in bioactive compounds. These bioactive compounds, including diosgenin, β-sitosterol, and saponins, offer various health benefits, such as antimicrobial, anticancer, and antioxidant properties, crucial in preventing degenerative diseases. This study aims to investigate the differences in phytochemical and antioxidant content of Gembili tubers from different locations. The research was conducted at the Phytochemical Laboratory, MARDI, in Selangor, Malaysia, where the total phenolic content (TPC) was analyzed using the Folin-Ciocalteu method, and the antioxidant capacity was assessed through the DPPH (2,2-diphenyl-1-picrylhydrazyl) assay using a UV spectrophotometer (Eon Biotek) at 517 nm. The results indicated that the total phenolic content and antioxidant values of yam bean tubers from the Serdang location in Selangor were higher than those from the Port Dickson location in Negeri Sembilan, measuring 1.6940 mg GAE/100g and 0.366 mg/ml in the DPPH test, respectively. Consequently, yam tubers cultivated in Serdang, Selangor, demonstrate greater potential as a source of natural antioxidants beneficial for health than those grown in Port Dickson
The Effect of Organic PGR Application from Mung Bean Sprouts Extract on the Growth of Stem Cuttings of Honey Water Apple Plants (Syzygium aqueum) in Danau Balai Village
Get PDFHoney water guava (Syzygium aqueum) is one of the newest high-quality commodities and is increasingly being cultivated by farmers in various regions. This study aimed to evaluate the effects of applying organic plant growth regulators (PGRs) derived from sprout extracts at different doses on the growth of water apple (Syzygium aqueum) plants. A completely randomized design (CRD) with a single treatment factor was employed. The results demonstrated that the 60 mL treatment of ZPT Organic Benefits Extract was the most effective in promoting plant growth, achieving an average height of 10.8 cm and five shoots at 4 weeks after planting (WAP), compared to the control treatment, which reached only 8 cm in height and two shoots. These findings indicate that the 60 mL dose of organic PGR extract from sprouts significantly enhanced growth and stimulated shoot development relative to the other treatments
The Effect of Kasgot Fertilizer Application on the Chemical Properties of Soil Planted with Cucumbers (Cucumis sativus L.)
Get PDFSustainable agriculture requires the prudent management of natural resources, including the judicious use of fertilizers and other inputs. One of the primary challenges faced by farmers is the decline in soil fertility resulting from the prolonged use of chemical fertilizers. This study aims to evaluate the effect of Kasgot fertilizer on soil chemical properties, specifically soil pH, organic carbon content, total nitrogen (N), available phosphorus (P), and available potassium (K), in cucumber cultivation. Soil sampling was conducted using a proportional sampling method, where sample points were selected based on soil availability and were representative of the cucumber cultivation area. The results indicated that, based on the analysis of phosphorus (P) and potassium (K) nutrient content, the treatment with 5 grams per planting hole was most effective in increasing phosphorus availability to 0.2907%, classified as high. Meanwhile, the treatments with 10 grams and 20 grams per planting hole were more effective in increasing soil potassium content to 0.0724% and 0.0708%, respectively, both of which were classified as moderate to high
Secondary Metabolite Content and Antioxidant Activity of Ethanol Extract of Tali Putri (Cuscuta australis) at Different Heights Places
Get PDFCuscuta australis (commonly known as Tali Putri) is a parasitic weed that extracts water, minerals, and nutrients from its host plants to sustain its life cycle. Among its shared hosts, Asystasia gangetica (Israel grass) is highly susceptible due to its soft stem structure, which facilitates haustorial penetration and efficient nutrient transfer. Although generally regarded as a harmful weed, C. australis has demonstrated pharmacological potential owing to its secondary metabolites and antioxidant properties, both of which are relevant in disease treatment. This study investigated the effect of altitude on the phytochemical profile, antioxidant activity, moisture content, and ash content of C. australis and its host plant. A survey method was applied across three altitudinal zones (lowland, midland, and highland) with seven replications per site. Laboratory analyses were performed at the Plant Physiology Laboratory, Faculty of Agriculture, Andalas University, and the Higher Education Service Institution (LLDIKTI) Laboratory. Data were analyzed using analysis of variance (ANOVA) with the F-test, and significant differences (p < 0.05) were further evaluated using Duncan's New Multiple Range Test (DNMRT). The results showed that C. australis grown at high altitude exhibited the highest antioxidant activity (173.35 µg/ml), moisture content (9.06%), and ash content (5.16%). Similarly, A. gangetica collected from highland sites demonstrated superior antioxidant activity (64.39 µg/ml), moisture content (8.82%), and ash content (7.07%). By contrast, altitude had no detectable effect on the phytochemical composition of either species, both of which consistently contained flavonoids, alkaloids, phenolics, terpenoids, and triterpenoids. These findings indicate that highland populations of C. australis and A. gangetica possess enhanced bioactive properties, suggesting that high-altitude habitats may provide the most suitable raw material sources for pharmaceutical applications
Optimizing Oil Palm (Elais guinensis L.) Carbon Management in Tidal Lands to Support Sustainable Plantations
Get PDFOil palm plantations in tidal areas face complex challenges in optimizing carbon management to achieve sustainable production. This study aims to analyze the dynamics of carbon stocks across various management systems of oil palm plantations in tidal zones and to develop optimization strategies for sustainable production. The research was conducted in Menten Village, Rambutan District, Musi Banyuasin Regency, South Sumatra, employing a factorial Randomized Complete Block Design with factors including water management systems (conventional, semi-intensive, conservation, optimization) and plant age categories (3–5, 6–10, 11–15, 16–20, and 21–25 years). CO₂ emissions and sequestration were measured using the LI-COR LI-8100A system; biomass was assessed through allometric equations and destructive sampling methods, while soil and water parameters were analyzed using standard procedures. The results demonstrated that the optimized system incorporating smart drainage achieved the best performance, exhibiting the lowest CO₂ emissions (6.2 Mg C/ha/year), the highest carbon absorption (21.5 Mg C/ha/year), and a positive net carbon balance (+15.3 Mg C/ha/year) with an efficiency of 346.8%. This system also increased fresh fruit bunch (FFB) productivity from 18.5 tons/ha/year under conventional management to 26.4 tons/ha/year, with superior quality metrics (oil content: 27.2%, acid value: 1.4%, crude palm oil yield: 25.2%). Total carbon stock progressively increased from 23.7 Mg C/ha in young plants to 147.9 Mg C/ha in mature plants, with an optimal sequestration rate of 17.8 Mg C/ha/year. The implementation of smart drainage, combined with IoT technology and biochar application, effectively optimized edaphic conditions by increasing soil pH to 4.8, raising organic carbon content to 4.2%, reducing bulk density to 0.68 g/cm³, and controlling salinity at 1.2 dS/m. This study confirms that oil palm plantations on tidal lands can achieve sustainability through precision agriculture practices that integrate precision water management, biochar application, and real-time monitoring to optimize the balance between productivity and carbon conservation
