Effect of the abiotic factor on Schleichera oleosa chlorophyll level

Chlorophyll in Schleichera oleosa is important to observe because S.oleosa is a tree plant that is often found on the road as a green plant. This role requires sufficient chlorophyll to maximize plant function for photosynthesis. Photosynthesis is supported by environmental factors. There are several environmental factors needed to maximize photosynthesis, namely altitude, humidity, ambient temperature, and light intensity. This study wanted to determine the effect of altitude, air humidity, ambient temperature, light intensity with chlorophyll content in S. oleose in several places. Altitude is measured using GPS. Measurement of air temperature and wind speed were measured using the Altimeter sights ler application version 2.0. Light intensity is measured using a lux meter. Soil moisture and soil pH were measured using a soil tester. Chlorophyll levels were measured using a spectrophotometer with a wavelength of 665 and 649, chlorophyll was calculated using the Wintermans and De Mots formula (1965). The results showed that chlorophyll content increased with increasing altitude. At the highest altitude of 833.6 m asl, the chlorophyll content is 53,770 with an ambient temperature of 270C which decreases at an altitude of 833.6 m asl.

Insilico Analysis of the Potential Phytoestrogens of Selected Alkaloid from ‎Soursop (Annona muricata) Leaves

Estrogen is an important hormone in the female reproductive system, as well as other systems in men and women. The decrease of estrogen levels mainly occurs in the menopause phase. The decrease of estrogen is one indication of the presence of various diseases such as cardiovascular disease. Decreased levels of estrogen can be treated by administering exogenous estrogen such as Estradiol-17β. However, long-term administration of estradiol plays an important role in tumor cell growth. Phytoestrogens are plant-basedpolyphenolic compounds that have a structure and biological activity similar to the estrogen. Phytoestrogens can be derived from alkaloid compounds, one of which is found in the soursop (Annona muricata) leaves. The purpose of this study was to analysis the potential phytoestrogens of selected alkaloid in the A. muricata leaves. The analysis was carried out using the insilico approach using molecular docking methods, pharmacokinetic analysis and druglikeness. The molecular docking results showed that the ligands could bind to the receptors on the specific binding site with the lowest binding affinity value approaching the control ligands, namely the Anonaine compound of -8.6 kcal / mol, followed by Xylopine compound of -7.8 kcal / mol and Annonamine of -7.0 kcal / mol. The results of pharmacokinetic and druglikeness showed that all ligand compounds have a good ability to be absorbed in the gastrointestine and have a good bioavalaibility as an oral drug.

Salicylic Acid from Gandapura Oil as an Inhibitor of Ethylene ‎Biosynthesis in Malus sylvestris L. Mill

Local apple production, especially Anna's apples, continues to decline. One of the Causes of the decline in local apple production is due to the disproportionate use of chemicals, which causes ethylene production in plants to increase. The purpose of this study was to examine the effect of salicylic acid on reducing levels of ethylene concentrations in Anna apple plants. This study used a completely randomized design (CRD) with a single factor, namely the treatment of various salicylic acid concentrations (25 ppm, 50 ppm, 100 ppm, 200 ppm). The results showed that salicylic acid was able to reduce the value of ethylene concentration in plants. Provision of salicylic acid concentrations starting at 25 ppm was able to inhibit ethylene biosynthesis by more than 90%. The best results were shown in samples treated with 200 ppm salicylic acid concentration. By using salicylic acid alternatives, farmers are able to save around Rp3,040,400 in costs in one harvest period. The percentage of costs for salicylic acid in one harvest period is 3.39% of the total production costs, while the cost of the import promoter is 7.92% of the total production costs
