Abstract

Due to the climate change and global warming, the biodiversity database has gained the attention of the government. In line with the Indonesian Biodiversity Strategy and Action Plan (IBSAP), we have collected plants with insecticidal activity based on the local wisdom. This program aimed to protect Indonesian biodiversity from deforestation along with the loss of the number of species. This research?s goal was to evaluate termiticidal and antifungal properties from some plant extracts collected from the Turgo forest area, Mt. Merapi National park, Java. Three potential plants were evaluated. Based on specimen identification, the three plant samples were Kina (Cinchona sp.), Kamadoh (Dendrocnide stimulans (L.f.) Chew), and Keremi (Homalanthus populneus (Geiseler) Pax). The phytochemical test showed that Kina contained alkoloid, falvonoid, saponin, and tannin, whereas Kamadoh and Keremi contained saponin and tanin, respectively. Overall, all plant extracts have the termiticidal activities and able to inhibit wood- decay fungi with the inhibition percentage around 60% - 100%. Leaf extracts of Kina (Cinchona sp) and Keremi (Homalanthus populneus (Geiseler) showed the highest activity as wood-decay fungi inhibitor. The disclosure of the potential of bioinsecticides from some plants originating from Mount Merapi is very important before being lost due to deforestation and the Mount Merapi disaster. Thus, the potential bioinsecticide in these plants can increase its economic value as a substitute for synthetic insecticides that are friendly to the environment.

Abstract

Mosquitoes are well known as vectors of hazardous diseases for human. Plant extracts can be used as an alternative for larval control due to they are a rich source of bioactive chemicals and safe for the environment. The present study investigated the larvicidal activity of crude extracts derived from leaf and flower of Brugmansia candida against the second larval instar of Aedes aegypti and Culex quinquefasciatus. The larval mortality was observed at 24 and 48 h exposure of both leaf and flower extracts, at the concentration of 100, 250, 500, and 1000 ppm. The 24 h exposure of both extracts at the concentration of 500 and 1000 ppm resulted in larval mortality rates were significantly lower than those of 48 h exposure. However, the mortality rate was not significantly different at the lower concentrations of crude extracts. The results also suggested that there was no significant difference in the larvicidal effect between leaf and flower extracts at 24 and 48 h exposure for all concentrations. The LC50 values at 48 h exposure for leaf extract were 789 and 791 ppm for Ae. aegypti and C. quinquefasciatus, respectively, whereas for flower extract were 772 and 780 ppm for Ae. aegypti and C. quinquefasciatus, respectively. Overall, B. candida showed larvicidal activity against Ae. aegypti and C. quinquefasciatus. This research contributes to new finding regarding the larvicidal activity of B. candida. This finding also supports the next study to develop B. candida as an alternative source for larval control agent.

Abstract

The Tau Taa Vana people live in the Bulang Highlands, Tojo Una-Una, in Central Sulawesi Province. The region's development has shaped the marginalization of forest-dwelling and forest-adjacent communities. From the 1980s to the 1990s, illegal logging networks served as the power holders, backed by Indonesia’s authoritarian regime of that time. Illegal logging destroyed a large part of the Tau Taa Vana's sacred forest (pengale kapali). As part of the massive logging agenda, the government launched many legal programs that further isolated the Tau Taa Vana people from their land. The first program was transmigration in 1995-1998, which converted sacred forests into plantation areas and worker camps. Meanwhile, the Tau Taa Vana people were forced to relocate from their forest livelihoods (pengale lipu). In 2014, development shifted towards government-supported gold and nickel extraction identified in the Tau Taa Vana people's traditional regions. The government's planned material extraction of the region has forced the Tau Taa Vana people to adapt traditional environmental management systems. In the past, the forest had three main functions, as the source of food, medicine, and livelihoods. Nowadays, those functions are reduced drastically and the sacred forest with the Kaju Marangka'a region as the center has lost its cultural importance. Tau Taa Vana people today use the remaining forests as the center of their resistance movements and consider it as their last bastion for cultural preservation. In this regard, the role of traditional healers (tau valia) has become even more critical amidst the lack of traditional elders.

Abstract

Lignocellulose materials, such as bamboo, rattan, and wood, have been largely used for furniture and crafts. On the other hand, the utilization of lignocellulose-like materials, which have a similar texture and appearance to those from nature, has been increasing recently due to their superior durability. This research aimed to identify the lignocellulose-like material using spectroscopy analysis, such as Raman and Near Infrared (NIR) which is well-known as a non-destructive, quick, and accurate approach for material identification. We investigated 4 types of lignocellulose-like materials that were provided by Dewan Serat Indonesia (The Indonesian Fiber Council) from an industry that produces them. The NIR analysis was performed at wavenumbers 10,000-4,000 cm-1. The natural lignocellulose (bamboo and wood) and the polymers (polyethylene and polyproline) were used as standards. Raman analysis was further employed to identify the composition of selected lignocellulose-like materials by comparing their spectra with the library software. The results showed that the original NIR spectra of lignocellulose-like and those natural materials were different, indicating that the NIR analysis can differentiate those materials. The NIR spectra of lignocellulose-like materials were similar to those of polyethylene spectra. Those lignocellulose-like were also identified as polyethylene due to the similarity of the Raman spectra and their library spectra.

Abstract

The study uncovers the promising anti-termite properties of Eucalyptus pellita bark extract, a resource often discarded as industrial waste in the pulp and paper manufacturing industry. It investigates the anti-termite efficacy of various extracts from E. pellita bark and identifies the extract with the highest activity, followed by a comprehensive phytochemical analysis. Samples of E. pellita inner bark, outer bark, and mixed bark were ground into 40–60 mesh powder and subjected to extraction using soxhletation techniques with successive extraction in increasingly polar solvents (n-hexane, ethyl acetate, and methanol solvents). The anti-termite activity of these extracts was evaluated using no-choice bioassays to determine the termite antifeedant activity through the weight loss percentage of test samples and the mortality rate of Coptotermes sp. Furthermore, Py-GCMS analysis was conducted on extracts exhibiting the highest anti-termite activity to elucidate their chemical composition. The findings revealed that methanol extracts from all three parts of E. pellita bark exhibited the most potent anti-termite activity against Coptotermes sp., as evidenced by the highest mortality rate (100%) and cellulose paper weight loss of 9.57 ± 6.66 mg. These methanol extracts were predominantly composed of phenolic compounds, particularly condensed tannins, suggesting a potential breakthrough in termite control. The findings indicate that E. pellita bark may be a sustainable and eco-friendly alternative to chemical pesticides for termite control. Furthermore, its utilization may facilitate waste valorization in the pulp and paper industry, thereby supporting environmental sustainability and economic efficiency.
