Plant anatomy can play vital role in plant taxonomy for successfully resolve taxonomic problems among different plant species. The anatomical studies of plant species living in coastal area of Kuantan, Pahang are scarce. Thus, the aim of this study was to identify the common, variation and diagnostic characteristics of leaf anatomy and micromorphology of selected plant species collected from Balok and Sepat beach area which can give additional information for identification of species. Four species studied namely Ipomoea pes-caprae (L.) R. Br., Calophyllum inophyllum L., Hibiscus tiliaceus L. and Stachytarpheta jamaicensis (L.) Vahl. Methods used were sectioning using sliding microtome, epidermal peeling and leaf micromorphology method using scanning electron microscope (SEM). The findings from this study showed that only three characteristics are similar among them which include the presence of collenchyma, sclerenchyma and mucilage cells or canals in either petiole or midrib of the leaves. Meanwhile, there are eight differences were observed which are types of stomata and trichomes, pattern of anticlinal wall and vascular bundles, type of epicuticular wax structures, cuticle ornamentations, size of epidermal cells and the presence of cell inclusions. The diagnostic characteristics identified in this study are closed-system of vascular bundle, presence of multicellular capitate glandular, 2-4 armed trichomes and 5-8 armed stellate trichomes and also flakes type of wax layers that can only be found in H. tiliaceus while 1:1 ratio size of epidermal cells can only be found in I. pes-caprae. The study reveals that leaf anatomy and micromorphology characteristics could be beneficial as an additional data for identification of species along the coastal area of Kuantan, Pahang.

Kaduk (Piper sarmentosum) is popular due to its culinary and medicinal properties and has been used traditionally in different parts of the world to cure many diseases and ailments. One of the studies which was conducted by Forest Research Institute of Malaysia (FRIM) shows that the extract from P. sarmentosum leaves contains antioxidant properties. However, a scientific study of its antioxidant level based on leaf maturity has not yet been conducted. Thus, this study aims to screen the antioxidant activity of P. sarmentosum based on the leaf maturity, from young, middle-age and matured leaves. The leaves were extracted by maceration using methanol and the antioxidant activity was determined by 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assay. Results showed that the middle-age leaves contain the highest antioxidant activity followed by the young and matured leaves. Hence, if P. sarmentosum’s leaves are to be collected for its antioxidant properties, it is best to harvest the middle-age leaves to gain the optimized yield of antioxidant properties.

Curcuma mangga and Bosenbergia rotunda which belongs to Zingiberaceae family are largely distributed in South East Asian countries including Malaysia. These plants have been traditionally used for treatment of various diseases. In this research we focused on determining the antioxidant and cytotoxic activity of C. mangga and B. rotunda ethanolic extracts. Initially, in this study, ethanolic extracts from rhizomes of C. mangga and B. rotunda were obtained through Soxhlet extraction method. 12.6% and 3.5% of crude extract were obtained from C. mangga and B. rotunda respectively. For MTT assay, the IC50 values are 207µg/ml and 31.96µg/ml for C. mangga and B. rotunda respectively. Meanwhile for the antioxidant activity using DPPH assay, C. mangga showed higher antioxidant activity with IC50 values of 1073µg/ml compared to B. rotunda with IC50 values of 578µg/ml. It can be concluded both extracts showed low inhibitory effect on MCF-7 cancer cells growth and DPPH free radical activity.

Ficus deltoidea or commonly known as ‘mas cotek’ is a herbal plant indigenous to Southeast Asia including Malaysia and Indonesia. This plant is popular for its medicinal values such as improve blood circulation, regain energy and enhance fertility naturally for both men and women. The main objective of this study is to develop in vitro clonal propagation method for rapid production of F. deltoidea using different concentrations of benzyl aminopurine (BAP) through shoot induction and multiplication, rooting and subsequent establishment in soil following acclimatization. Surface sterilization of the leaf explants was done using mercury chloride and ethanol as the disinfectants. Pre-treatment of the explants with carbendazim successfully reduced the occurrence of fungal contamination. At the end of the experiment, no shoot and root induction were observed but calli were successfully induced on MS medium containing 1.0, 1.5, 2.0, 2.5 and 3.0 mg/l BAP, with calli induced from 3.0 mg/l BAP were bigger and healthier. In short, the higher the concentration of BAP used, the higher tendency for the explant to induce callus.

In Buenos Aires, Argentina there are many architectonic heritage objects that represent the history of the population of different places with different degree of deterioration and conservation, so their study and survey were necessary to avoid the complete loss of it. During the study of heritage assets in towns, villages, and cities of Buenos Aires that the LEMIT makes more than 20 years ago, numerous architectonic heritage assets were found with different degree of deterioration and conservation. As result of some surveys, important restoration and conservation interventions were done preserving province heritage. Thus, the aim of this paper was the study of the materials deterioration state from the first ranch built by the settlement of the Jewish settlers in 1891, in Algarrobos city, Carlos Casares, Buenos Aires. This ranch was the first houses of Jews when they arrived from Russia. The material analysis here presented allowed to recognize its state of deterioration and conservation through discerning if these materials were from the mentioned age and consequently, providing fundamental information to know part of settlement history formation. On the other hand, its study allowed generating a plan of interventions and conservation in short – and medium- term.

This study examined the mangrove degradation in Pahang River Estuary, Pekan sub-district, Pahang between 1990 and 2017 using supervised classification. Landsat 8 OLI and Landsat 5 TM images of Pahang River Estuary have been analyzed using supervised classification and field survey. Based on the accuracy assessment, the confusion matrix for supervised classifications ranged from 77% to 81%. Kappa coefficient (K) for supervised classification ranged between the value of 0.67 and 0.72. The total mangrove covers in 2017 was 1,535.40 ha, decreased by 43.7% or 670.80 ha from its total area of 2,206.20 ha in 1990. The expansion of development area was observed in the past 27 years. Several other causes of mangrove degradation were identified during field survey, including sand mining activities along riverbank, mangrove clearing for aquaculture and agriculture. The rapid development within the coastal area and estuary had suppressed the mangroves propagation over the years. Long term monitoring of mangrove distribution is crucial to ensure the sustainability of the mangrove ecosystem.

Herb Phyllanthus niruri (P. niruri) is known to have various pharmacological functions including anti-diabetic properties. In this research, protein extracts from different plant parts (leave, fruit and stem) of P. niruri were investigated for their anti-diabetic potential through α-amylase and α-glucosidase enzyme inhibition assays. For the enzyme inhibition assay, fruit was found to have the highest inhibition percentage (90.0%) against α-glucosidase followed by leave (62.6%) and stem (38.4%). The similar patterns were also recorded for the α-amylase enzyme inhibition assay, in which, fruit showed the highest inhibition percentage (64.1%) followed by leave (33.3%) and stem (18.2%). The findings of this research suggest that fruit of P. niruri is a potential plant part with regards to anti-diabetic properties since it exhibits the highest inhibition activity against both α-amylase and α-glucosidase enzyme compared to leave and stem.
