Abstract

Polyurethane is polymer synthetic which is formed by reaction between polyols and polyisocyanates. Polyols are compounds which contain two or more hydroxyl groups. Polyurethane can be applied in various forms, such as foam, elastomeric, coating and adhesive. In this work, we developed polyurethane foams by using polyols based on palm oil. Palm oil based polyols as soft segments in the polyurethane backbone accelerate biodegradable process of the polyurethane. Biodegradability is the ability of material to be utilized as a carbon source by microorganisms and converted safely into carbon dioxide, biomass and water. Commercially available polyurethane foams are usually produced from petrochemical based polyols that they are not biodegradable. The biodegradability study was conducted by using Aspergillus niger (fungi) and Pseudomonas aeruginosa (bacteria), with variation of method and media for biodegradation. Rigid polyurethane foam was synthesized by using one shoot process method, which is reaction between palm-based polyol mixture and methylene diphenyl diisocyanate (MDI) at room temperature. The effect of variation of ratio of polyisocyanates (NCO) as hard segment and polyols (OH) as soft segment to the properties of polyurethane foams were studied in detail. Study of the effect NCO/OH ratio was conducted with variation ratio of 0.8, 1.0 and 1.2. Increasing hard segment (NCO) ratio to the soft segment (OH) affected in the decreasing of hydrophilicity of foam. Thus, the penetration of water into bulk of polymer decreased. The biodegradability of foam was also affected by the soft segment ratio on the polymer backbone.

Abstract

Environmental changes caused by oil palm plantation activities can affect the diversity of nocturnal insects that play important roles in the ecosystem as pollinators, decomposers, predators, and food sources for other insects as well as bioindicators. This study aimed to determine the levels of diversity, evenness, and dominance of nocturnal insects at two stations with different oil palm planting ages in Seruyan Regency. This study used a descriptive quantitative approach with an exploratory survey method. Nocturnal insects were collected from replanting and non-replanting oil palm areas using light traps equipped with UV lamps. The insects were identified to the species level, and data were analyzed using the Shannon–Wiener diversity index (H′), Pielou’s evenness index (E), and Simpson’s dominance index (C) with the PAST software. The results showed that from a total of 454 individuals, 15 species of nocturnal insects were successfully identified, originating from 6 orders, namely, Coleoptera (Laccophilus gentilis, Protaetia acuminata, Pangaeus bilineatus, Adoretus versutus, Denticollis linearis, Eumorphus bulbosus, Sirthenea flavipes, Cicindela gallica), Hymenoptera (Vespa affinis, Tetraponera rufonigra), Hemiptera (Pangaeus bilineatus), Odonata (Agriocnemis pygmaea), Lepidoptera (Hypochrosis subrufa, Chytolita morbidalis), and Orthoptera (Gryllus assimilis). The most dominant species was Pangaeus bilineatus with 143 individuals, while the species with the lowest number of individuals was Cicindela gallica with 3 individuals. The Shannon‒Wiener diversity index (H') value of 1.558 (Station I) and 2.129 (Station II) indicates moderate diversity, the Pielou evenness index (E) value of 0.59 (Station I) and 0.65 (Station II) indicates a fairly even distribution, and the Simpson dominance index (C) value of 0.72 (Station I) and 0.85 (Station II) indicates no extreme species dominance. The study revealed moderate nocturnal insect diversity with balanced species distribution, indicating a stable oil palm ecosystem and supporting their role as bioindicators of ecological health.

Abstract

Green water in fish ponds, caused by algal blooms, harbors a diverse array of microalgae species and is commonly observed in aquaculture settings. This resource-rich water source holds promise for research focused on microalgae cultivation at a laboratory scale, serving as a valuable starter sample for such investigations. Preliminary observations suggested that the predominant species in such green water habitat belonged to the genus Micractinium Fresenius 1858. An effective isolation technique of this microalgae species is necessary, not only to reduce the contamination of the rotifers but also to purify the starter cultures. Although automated microalgae isolation techniques have been developed recently, such as using Flow Cytometry via Cell Sorting, traditional isolation techniques are still relevant. One of the traditional microalgae isolation techniques that has been widely used for many years is the dilution technique. This study aims to isolate Micractinium pusillum Fresenius from fish ponds using the modified dilution technique: SDE (sedimentation, dilution, and enrichment). The dilution results showed that rotifer contamination was reduced at a dilution of 10─3 and the density of microalgae was also reduced. At this dilution level, only one type of microalgae was observed, i.e., Micractinium pusillum Fresenius. which was then cultured for enrichment using a simple photobioreactor. This 10-3 culture was observed to grow well during the enrichment stage for 10 days. These results indicate that the SDE isolation technique can be effectively used to isolate microalgae from green water, especially for Micractinium pusillum which is the most abundant microalgae species in green water in this study.

Abstract

Tropical peat forests of Kalimantan harbor diverse wood-decaying fungi with strong ligninolytic potential, yet their functional enzymatic characteristics remain poorly documented. This study prospectively examined the physiological expression of laccase production in native fungi isolated from the Universitas Palangka Raya peat swamp forest, Central Kalimantan. Three stable pure cultures were obtained: MIPA 2 (Ganoderma sp.), MIPA 4 (Trametes sp. 1), and MIPA 8 (Trametes sp. 3). All isolates produced extracellular laccase but showed clear differences in growth and enzyme productivity. Growth analysis revealed distinct radial expansion rates, with MIPA 2 exhibiting the fastest mycelial growth (13.64 mm/day). The faster radial growth of MIPA 2 suggests higher metabolic activity and biomass formation, which may contribute to its superior laccase production compared to the other isolates. Qualitative screening on syringaldazine-amended PDA also confirmed extracellular laccase activity in all isolates, with activity levels ranging from weak (+) to strong (+++). Quantitative assays in potato dextrose broth and modified glucose–peptone medium revealed strong nutrient-dependent regulation of laccase biosynthesis, with MIPA 2 reaching 93.71 U/L on day 21. The pronounced stimulation by organic nitrogen indicates ecological adaptation to acidic, nutrient-limited peat environments and distinguishes these isolates from many previously reported Ganoderma and Trametes strains that typically require external inducers for high activity. These findings demonstrate that peat swamp ecosystems represent not only a geographic source but also a reservoir of fungi with distinct ligninolytic expression profiles and potential biotechnological relevance.
