Abstract
The development of bamboo as a raw material for construction materials has drawbacks, including low physical properties. Therefore, this work aimed to determine the physical and mechanical properties of laminated boards modified with citric acid, boric acid, and polystyrene. In addition, the study analysed the optimum immersion time and the phenomenon of the modifications provided. Two-step conditions were designed for the immersion of bamboo lamina. The first

Abstract
Fibrovascular bundle (FVB) of Salacca sumatrana fronds is a natural fiber derived from palm plants. The fiber typically had long dimensions and the potential to be used as raw material for oriented boards. Therefore, this study aimed to evaluate the properties of oriented boards made from alkaline- modified FVB of Salacca sumatrana frond. FVB was modified with an alkali pre- treatment, comprising 1% NaOH, 1% NaOH + 0.2% Na2SO3, and 1% NaOH + 0.4% Na2SO3 to

Abstract
The Mediterranean Sea is a region characterized by high seismic activity, with at least 200 tsunami events recorded from the fourth century to the present twenty-first century. Numerous studies have been conducted to understand past tsunami events, earthquake–tsunami generation, tsunami recurrence periods, tsunami vulnerability zones, and tsunami hazard mitigation strategies. Therefore, gaining insights into future trends and opportunities in Mediterranean
Abstract
Numerous countries have deployed significant efforts to reduce the amount of CO2released intothe atmosphere. Carbon capture and storage is widely regarded as a mitigation technique that cansignificantly reduce CO2emissions. A crucial stage in carbon capture and storage is CO2adsorptionusing a membrane. Cellulose acetate has demonstrated excellent properties as a membranematerial. In this study, we examined the potential of cellulose acetate membrane (CAM) for

Swietenia mahagoni is one of the commercial timbers in Indonesia. Mahogany heartwood is an important characteristic as it relates to the natural durability and aesthetics of the wood. Lipophilic extractives are known to be involved in the heartwood formation process. Therefore, this study aims to determine the lipophilic compounds associated with heartwood formation. The n-hexane extract from sapwood and heartwood samples (1 to 5 years) was analyzed by gas chromatography-mass

Mount Merapi National Park (TNGM) is one of the active volcanos in Indonesia. It has past volcano eruption history since 1911 up to date. Specifically, Plawangan Hill, a part of the TNGM, has periodically experiencedvolcanic eruptions.This study aimedto examine the quantities of nutrients in the soil and the vegetation growthin affected areasandto estimate when it would be feasible to start planting on Plawangan Hill shortly after a volcanic eruption.A field
Abstract
Intensive silviculture plays a crucial role in selecting superior clones with high productivity. The use of superior clones needs to be accompanied by appropriate environmental conditions. The arrangement of growing space is one way for teak clones to grow optimally and produce quality wood products. It can choose initial spacing in the early growth phase and thinning intensity in the later growth phase. This study aims to assess and determine the growth of
Abstract
Reclaiming tropical coal mines is a formidable task. The symbiosis between AMF and plants like Nauclea orientalis is crucial for thriving in tough environments. This study aimed to assess the potential of native AMF and N. orientalis in overburden pit soil for post-mining reclamation. Fifteen AMFs isolated from post-coal mining were screened for nutrient uptake, plant growth, and colonization using Sorghum bicolor as hostplant. The top three AMFs were rDNA
