“…The lignin content before being treated was in the high category, which was more than 33%, but after being immersed in KMnO4 2% and NaOH 5%, the lignin level was changed to the low category which is less than 18% [23]. Research using Borassus fruit fiber treated with NaOH also showed a reduction in lignin levels [16].…”

The choice of natural fibers as a composite reinforcing material is related to the advantages of being cheap, abundant, renewable, and environmentally friendly. This research was conducted to study the effect of de-lignification treatment on the properties of purun tikus (Eleocharis Dulcis) fiber. Purun tikus fiber has been modified with the alkaline treatment of KMnO4 2% and NaOH 5%. This treatment was mainly applied to improve the physical and chemical properties of purun tikus fiber. Changes in chemical characteristics (water, lignin, cellulose, and hemicellulose), physical (density), mechanical (tensile strength), morphology, and elemental content of purun tikus before and after treated with alkaline were studied. The measurements showed an increase in water content and density while lignin, cellulose, and hemicellulose were decreased. Thus the alkaline treatment of KMnO4 2% and NaOH 5% reduced lignin, cellulose, and hemicellulose of the purun tikus fiber to reduce the size of the fibers, as shown in SEM measurements. There was a change in elemental content after being treated with KMnO4 2% and NaOH 5%. NaOH treatment was better than KMnO4 treatment in terms of removing lignin and hemicellulose in purun tikus fiber. Although the tensile strength of the purun fibers treated with KMnO4 2% and NaOH 5% were lower than untreated, with less lignin, cellulose, and hemicellulose, it is expected that these fibers will blend better in the composite and improved its mechanical properties.

Termites are one of the social insects that play a significant role in the decomposition process in tropical forests. This arthropod not only attacks dead plants but also live plants. Information on termite attacks on plants in tropical forests is still very scarce in Indonesia, especially in regenerating forests. This study aims to reveal the role of termites in infesting plants in Soraya Research Station Forest, Leuser Ecosystem. Plant data collection using sampling plots and termites. Data collection using a standardized sampling protocol will be analyzed by descriptive analysis. We found 37 families, 59 genera, and 90 species of plants. Dipterocarpaceae, Meliaceae, Anacardiaceae, Ebenaceae, Euphorbiaceae, Moraceae, and Myristicaceae are dominant plant families in the forest. Plant strata attacked by termites include trees, poles, and saplings. Shorea multiflora (Burck) and Streblus elongatus (Miq.) are the most dominant living plant-attacked species. This study also describes the preferences of termite attacks on different plant species in the Soraya Regeneration Forest.

Abstract. Septiasari A, Balgis M, Lathifah MN, Hanugroho PD, Setyawan AD. 2021. Identification and potential of vascular plants in the karst ecosystem of Somopuro Cave, Pacitan, East Java, Indonesia. Intl J Trop Drylands 5: 75-83. Karst areas are composed of limestone hills or mountains formed over hundreds or even millions of years. Karst landforms vary according to the formation process. With a unique formation, karst land is a place to live for unique organisms. The karst area is like a natural laboratory that contains various phenomena of living organisms and plays an important role in the progress of science. One of the plants that live in the karst environment is a vascular plant and is rarely discussed among researchers. No one has ever investigated the vascular plants around Somopuro Cave, so this research became interesting to discuss. This paper aims to know the diversity of vascular plants in the Somopuro Karst Cave, Pacitan, East Java, Indonesia area, and the potential species. The research was conducted in November 2021, using a survey method. Based on observations around Somopuro Cave, vascular plants are grouped based on their habitus; there are 5 groups, namely trees, shrubs, herbs, vines, and epiphytes. The collection of plants in the karst area of the Somopuro Cave contains 103 species from 51 families. Results revealed that the most common vascular plants are Asteraceae, Araceae, Fabaceae, and Euphorbiaceae family. Six potentials can be utilized from vascular plants in the Somopuro Cave Area: medicinal plants, ornamental plants, foodstuffs, wood-producing plants, animal feed, and energy sources.
