Clinacanthus nutans is a well recognized medicinal herb for its high phytochemical contents. Several aspects may contribute to the phytochemical contents, and thus determine the quality and efficacy of an herb. An experiment was conducted using a completely randomized design (CRD) with five replications, in a factorial arrangement of treatments. including two plant parts harvested at two different stages such as young leaves, young stems, matured leaves and matured stems, and four different storage durations such as 1, 2, 3 and 4 days. The study was aimed at determining how storage duration affects selected phytochemical contents of different plant parts of C. nutans at different harvesting stages. Total phytochemical content, total flavonoids content and DPPH radical scavenging activities are higher in young plants than in old plants, moreover, all those compounds are higher in leaves than in stems, and decrease gradually due to storage. Phytochemical, ascorbic acid and chlorophyll content of C. nutans differ among different plant parts and change due to storage. In general, young plant parts contain higher amount of phytochemicals, ascorbic acid and chlorophyll compared with matured parts confirming that phytochemicals content of C. nutans decreases when plants tend to maturity. Prolonged storage reduces phytochemical, ascorbic acid and chlorophyll content of C. nutans,which demands fresh use of this medicinal herb to avoid phytochemical losses. Further research focusing on the proper storage is necessary to minimize phytochemicals losses of C. nutans.

Gambir (Uncaria gambir Roxb.) is an important Indonesian export commodity used in the pharmaceutical, food, and leather tanning industries. The Cubadak variety is one of the superior varieties with high flavonoid and tannin content and resistance to pests and diseases. One of the obstacles in gambir propagation is uneven seedling growth, which affects plant productivity and quality. One approach to address this issue is by regulating light intensity through shading during the gambir seedling phase. This study aims to investigate the effect of shading intensity on the growth of Cubadak gambir seedlings. The study was conducted at the Experimental Garden of the Faculty of Agriculture, Andalas University, using a Completely Randomized Design (CRD) with four levels of shading intensity (40%, 50%, 60%, and 70%) and three replications. Data were analyzed using an F-test at the 5% level, followed by Duncan’s New Multiple Range Test (DNMRT) at the 5% significance level. The results of the study indicated that 60% shading provided the best effect on gambir seedling growth, as evidenced by increased plant height, number of leaves, leaf area, and other morphological and physiological parameters. A shading intensity of 60% is recommended as the optimal condition for the growth of Cubadak gambir seedlings.

In principle, shallot can adapt to all altitudes. But in West Sumatera, it is generally cultivated in the highland. The problem is the area in the highland is very limited while the area in lowland land is dominated by Ultisol soils. The type of soil in Agricultural Faculty experimental field at Andalas University is Ultisol (250 asl) but the chemical properties slightly change, such as nitrogen, phosphor and potassium higher than usual otherwise SO42- and Ca-dd is still very low. This study aimed to obtain the best organic fertilizer and ZA fertilizer on the growth, yield and quality of shallot bulb on recovered Ultisols. The research was a-two factorial experiment with 3 replications in Completely Randomized Design. The first factor is the application of various types of organic fertilizer, which include three levels which are guano, chicken manure, and oil palm empty bunches (OPEB). The second factor is ZA fertilizer dosage (0, 100, and 200 kg/ha). Data were analyzed using the F test with a 5% level, and if there were significant differences, the analysis continued with the Duncan’s New Multiple Range Test (DNMRT) at a 5% level. The result showed that the development of shallots on recovered Ultisols brings hope. The yield of chicken manure and guano are higher than oil palm empty bunches and in accordance with the description of Bima Brebes varieties around 9 t/ha. Even guano could produce dry bulbs around10,54 t/ha without giving ZA. Moreover, guano fertilizer gave the best Sulphur content on every dose of ZA.

Cocoa seeds are classified as recalcitrant and have a pulp layer containing corrosive substances such as abscisic acid; if not properly cleaned, this layer can inhibit the germination process. To date, manual pulp cleaning using scouring ash remains ineffective and time-consuming. An alternative method is chemical treatment, such as using hydrochloric acid (HCl). The application of HCl at specific concentrations has been shown to effectively dissolve and break down the pulp layer attached to the seeds without damaging the seed tissue. This study aims to evaluate the effectiveness of various HCl concentrations for pulp extraction and their impact on the viability and vigor of cocoa seeds of the TSH 858 variety. The research was conducted at the Seed Technology Laboratory of the Faculty of Agriculture, Andalas University, employing a Completely Randomized Design (CRD) with five treatments: 0% HCl (control), 1% HCl, 3% HCl, 5% HCl, and 7% HCl. Each treatment was replicated four times. Data were analyzed using the F-test at a 5% significance level, followed by Duncan's New Multiple Range Test (DNMRT) at the same level if a significant effect was detected. The parameters measured included seed moisture content, germination rate, seedling height, root length, and vigor index. The results indicated that treatment with 5% HCl yielded the best outcomes for seed vigor, particularly in enhancing root length, but had no significant effect on seed viability. Therefore, 5% HCl is effective for extracting cocoa seed pulp without compromising viability and can improve seed vigour by promoting root growth.
