Phenolic is well known as a secondary metabolite that plays an important role in plant defense system. Information about the fungi-impeded role of secondary metabolite is important in achieving success of artificial agarwood production, in that fungi induction imparted to the selected potential trees will be more effective and efficient. This research was aimed to investigate the correlation of agarwood tree phenolics in relation with the susceptibility of corresponding trees to Fusarium solani attack in the formation of agarwood and observing total phenolics content of Aquilaria crassna and Aquilaria microcarpa trees prior to inoculation. Twenty trees of A. microcarpa at Carita, a Forest Area for Special Function (FASF) and ten of A. crassna at Dramaga Research Forest were inoculated with isolate of F. solani in spiral pattern around their stem from ground level to about 1.5 m in height. Prior to inoculation, wood strips were taken off from the stem for total phenolics content. The result revealed that total phenolics content and infection area tended to have a negative correlation. Since the quantity of agarwood is highly related with the infection area, then trees with lower phenolics content should be selected for the more effective and efficient artificial agarwood production.

This paper provided information regarding artificial agar wood production. Fungi are considered as biological agent for agarwood formation and agarwood is assumed as tree defense mechanism product. This research was aimed at investigating the anti fungal activity (AFA) of Aquilaria crassna, one of the agar wood-producing trees, against Fusarium solani in vitro. Aquilaria crassna wood mill was extracted by 70% ethanol to investigate the anti fungal activity. The result are Aquilariacrassnaexhibited low extractives content, which was only 2.0% (w/w) and a low anti fungal activity in vitro, especially for ethanol extract. However, further fractionation and bioassay showed that the most active component was likely in the ethyl-acetate soluble fraction that exhibited strong anti fungal activity (52.5%) at 4.0% of concentration.

One environmental service provided by A. crassicarpa plantation is extrafloral nectar which has been widely used for beekeeping since 2019. Nevertheless, nowadays between apiaries practiced unfair competition since there were price fall led by oversupply and low demand after covid pandemic ended. Thus, evaluating the cost structure, profitability, and its feasibility value are critically required. The study's objectives were to 1) evaluate cost structure, revenue and profitability and 2) to conduct a feasibility analysis of each apiary type. This study was conducted from in 2019 to 2022 at the Siak Regency, Riau, Indonesia. Structure interviews combined with desk studies were carried out to collect the data. Data were analyzed based on cost structure, revenue, profitability, and feasibility analysis. All types of apiaries were feasible since they could cover variable and fixed costs. However, it revealed that all types of apiaries experienced minus in profitability in the fourth of financial year. In general, variable cost relatively increased to the level of 50% of total cost in the fourth year. In contrast, fixed cost was relatively declined to less than 50%. Apiaries managed two rits had a better performance in cost structure to face the competitive market followed by apiaries managed three rit. Meanwhile, apiaries managed rit one experienced such a difficult challenge to survive.

Gatiga Snack MSMEs, a chip producer in South Lampung, faces tough competition and requires effective marketing strategies to grow. This study aims to develop and select strategies that can be implemented by Gatiga Snack using SWOT analysis and QSPM. Based on the SWOT analysis results, 18 recommended strategies were obtained. These strategies are then prioritized using QSPM analysis. There are three recommended strategy implementation periods. In the first period, six strategies were recommended that could be implemented. The highest TAS score among the strategies in the first period was forming a special marketing team for managing the Gatiga Snack MSME business (WO4), amounting to 7.296. In the second period, six strategies were also recommended that could be implemented. An intensive promotional strategy by creating a schedule of online and offline routine promotional activities (WO2) resulted in the highest TAS score of 7.141 in the second period. The third-period strategy consisted of six strategies with the highest TAS score of 7.031, namely building a brand image by making reviews or testimonials about the quality of Pangas Catfish Skin Chips’s Gatiga Snack so that new consumers would trust and be interested in buying (ST3).
