Project-based learning (PjBL) is a student-centred approach focusing on experiential learning. The approach has been widely used in the field of sciences and mathematics but not in social sciences, particularly in English writing skills. As PjBL gains popularity as one of the 21st century teaching and learning approaches, there is a need to identify the trends, key authors, significant countries, and findings related to PjBL in writing. This paper presents a systematic literature review (SLR) conducted on 17 articles from the year 2018 to 2023 from the Scopus database following the PRISMA guideline. The study focused on PjBL and English writing, employing a systematic literature review to analyse trends, countries, authors, and journals. The analysis reveals dynamic trends of PjBL in the writing field. While the publication output fluctuated over the years, Indonesia emerged as a major contributor, signifying a global interest. A diverse distribution of articles across journals and countries underscores the global impact of PjBL, with notable contributions from Malaysia, China, and Russia. This paper synthesises the key themes from the literature review, emphasising the improvement in writing skills through PjBL and its challenges. The findings underscore PjBL's potential in transforming English writing education, emphasising the importance of addressing challenges for effective integration. The study contributes to the literature through a systematic analysis, providing insights into the trends and recommendations in PjBL in English writing research. Further research should delve into refining PjBL methodologies to maximize its innovative potential in English writing instruction. [ABSTRACT FROM AUTHOR]

Conventional bitumen pavement is no longer suitable for handling increasing loads and weather variations, which cause road deterioration, Thus, the modification of bitumen has been suggested to counter this issue. This study provides a detailed assessment of various additives for modifying natural rubber-modified bitumen used in road construction. This work will focus on the use of additives with cup lump natural rubber (CLNR), which has recently started to gain attention among researchers, especially in rubber-producing countries such as Malaysia, Thailand and Indonesia. Furthermore, this paper aims to briefly review how the addition of additives or modifiers helps elevate the performance of bitumen by highlighting the significant properties of modified bitumen after the addition of modifiers. Moreover, the amount and method of application of each additive are discussed further to obtain the optimum value for future implementation. On the basis of past studies, this paper will review the utilisation of several types of additives, including polyphosphoric acid, Evotherm, mangosteen powder, trimethyl-quinoline and sulphur, and the application of xylene and toluene to ensure the homogeneity of the rubberised bitumen. Numerous studies were conducted to verify the performance of various types and compositions of additives, particularly in terms of physical and rheological properties. In general, additives enhance the properties of conventional bitumen. Future research should investigate CLNR because studies on its utilisation are limited. [ABSTRACT FROM AUTHOR]

Strobilanthes crispa (L.) Blume (S. crispa) is a folklore medicinal plant of the genus Strobilanthes (Acanthaceae), traditionally used in Malaysia and Indonesia to treat various diseases such as breast and uterine cancers, diabetes mellitus, hypertension, gastrointestinal and kidney diseases, typhoid, jaundice, piles, high cholesterol, and ulcers. Several studies have shown that S. crispa contains a variety of phytochemicals, including terpenoids, flavonoids, phenolic compounds, sulfur-containing, steroids, chlorophylls, benzofuran, fatty acids, and other simple metabolites. Furthermore, based on its traditional uses, S. crispa has demonstrated a wide range of in vitro and in vivo pharmacological activities. These activities include antihyperglycemic, antioxidant, antimicrobial, wound healing, anticancer, anti-trypanosomal, anti-inflammatory, anti-obesity, anti-urolithiatic, anti-angiogenic, and vasorelaxant activity. The paper aims to provide a comprehensive review of the current understanding of traditional use, toxicity, phytochemicals, and pharmacological studies of S. crispa, thereby validating its ethnopharmacological applications and exploring possible research opportunities.

In the era of globalisation, decreasing synthetic resources, especially petroleum, have encouraged global communities to apply biomass waste as a substitute material for green technology development. The development of plastic products from lignocellulosic fibre-reinforced composites has been a hot topic among material scientists and engineers due to their abundance, sustainable in nature, and less toxic towards health. For the Malaysian scenario, sugar palm is a plant found in the wild and locally planted in certain areas in Malaysia and Indonesia. Generally, sugar palm can be harvested for traditional foods, fruits, starch sugar (gula kabung), and alcohol, whereas sugar palm fibre (SPF) is used in conventional products (brushes and brooms). Various researchers are working on the characterisation of fibre and its composites for engineering and packaging products. The main drawback of SPF is its hydrophilic behaviour, which leads to high moisture uptake and inhibits a good bond between the fibre and the matrix. Thus, a solution for this problem is by implementing chemical treatments on the fibre. From the literature review, no comprehensive review paper has been published on the influence of chemical treatment on the mechanical behaviour of SPF-reinforced polymer composites. Thus, the present review examines recent studies on the mechanical properties of sugar palm lignocellulosic fibres with various chemical treatments to evaluate their potential in structural applications.

Background: This study aims to explore the Indonesian tourists' demand for medical tourism services in Malaysia. The study also investigates the Indonesian medical tourists' profiles and their preference for Malaysia for medical treatment services. Methods: This study conducted interviews with 49 potential patients from Indonesia who received cardiac treatment at the National Heart Institute (IJN) in Kuala Lumpur, Malaysia. Results: The findings indicate that the key motives of Indonesian tourists travelling to Malaysia for medical treatment are their disappointment with medical practices and inadequate expertise in Indonesia. Besides, they are motivated by peer recommendations, medical expertise, transparency, administration and hospitality in Malaysia. The study findings show that Indonesian medical tourists can be acknowledged as an elite group with stable and above-average income. Conclusion: Results from the study enable medical tourism marketers to better target and segments their potential medical tourists and develop a strategic medical tourism marketing roadmap. This study shows that the high demand for medical tourism is related to Malaysia's availability of niche medical services. Besides, this paper expands the understanding of medical tourists' decision-making and argues its implications for Malaysian health policy and healthcare delivery for the medical tourism industry sustainability.

It is common for ethnic Malay in Indonesia and Malaysia to use Nepenthes ampullaria as food containers. However, the use of Nepenthes as part of a cultural tradition has been found only in Kerinci Regency, Jambi. This study explores the local wisdom in utilizing and maintaining the presence of N. ampullaria in Kerinci. Data collection through open-ended and deep interviews through participatory observation methods. Data analysis and presentation are delivered descriptively. Lemang is a compulsory item to be served in traditional ceremonies of kenduri sko. There are two types of lemang in Kerinci, lemang bamboo and lemang kancung beruk. The latter is found only during the kenduri sko tradition in Kecamatan Gunung Raya and Bukit Kerman. Therefore, the existence of lemang kancung beruk in these two sub-districts has become obligatory and has no other comparable substitute. In Gunung Raya and Bukit Kerman, the Kenduri sko is held four times a year. The need for N. ampullaria for kenduri sko in these two sub-districts is enormous. For the event, each household needs at least 500 to 2000 pitchers of N. ampullaria. The people of Kerinci harvest N. ampullaria directly from the wild to fulfill the need. The population of N. ampullaria that still survives in its natural habitat is evidence of the success of the local community in maintaining the existence of N. ampullaria in Kerinci. Method and schedule arrangements can allow the population of N. ampullaria to recover. [ABSTRACT FROM AUTHOR]

Oil palm plantations have expanded rapidly in Southeast Asia, particularly in Indonesia and Malaysia. A lot of products, including food and other edible products, oleo-chemicals, cosmetics, personal and household care, pharmaceutical products, and biodiesels are derived from palm oil, thus making them one of the most economically important plants. After 25–30 years of age, the palms are felled and replaced due to declining oil production. Oil palm trunks (OPT) are considered significant waste products. The trunks remain on the plantation site for nutrient recycling or burning. This increases insect and fungi populations causing environmental problems for the new palm generation or air pollution due to the fire. Up till now, OPT has received less attention in research studies. Therefore, this review summarizes the utilization of OPT into products made of oil palm fibers mainly derived from OPT and its application as the substitution of wood panel products. Some research works have been carried out on oil palm fibers that are derived from OPT for exploiting their potential as raw material of composite panel products, which is the objective of this review. Areas of development are processed into various conventional composite panel products such as plywood and laminated board which are usually predominantly made of wood and bonded by synthetic resins, particleboard with binder, or binderless and cement board which is arranged with wood as a minor component. All of the products have been presented and described technically according to best knowledge of the authors and literature review. [ABSTRACT FROM AUTHOR]
