Abstrak: Analisis proximat dua belas jenis buah-buahan yang biasa dimakan oleh kera ekor panjang seperti Arenga pinnata, Areca catechu, Terminalia catappa, Elaies guineensis, Lagerstroemia tomentosa, Mangifera indica, Cascabela thevetia, Muntingia calabura, Musa spp., Artocarpus heterophyllus, Ficus tinctonia ssp. gibbosa dan Ficus microcarpa telah dijalankan dengan objektif khusus untuk menentukan kandungan nutrien makanan kera ekor panjang. Hasil kajian menunjukkan susunan nutrien yang berikut; serat, protein, lemak dan abu. Berdasarkan keputusan daripada analisis kimia, peratusan tertinggi kandungan serat (52.7%), protein (9.9%), lemak (77.2%) dan abu (8.5%) terdapat dalam A. catechu, T. catappa, E. guineensis dan C. thevetia. Kandungan nutrient daripada dua belas jenis buah-buahan ini didapati berbeza antara satu sama lain (Analisis ANOVA: serat, F (11, 24) = 87.978, p < 0.05; fiber, F (11,24) = 28.886, p < 0.05; lemak, F (11,24) = 2081.396, p < 0.05 and abu, F (11,24) = 41.011, p < 0.05). Kandungan serat adalah yang paling tinggi di antara keempat-empat jenis nutrien yang dikaji. Maka, A. catechu mempunyai kandungan serat tertinggi di antara buah-buahan yang diuji, E. guineensis mempunyai kandungan lemak tertinggi, T. catappa mempunyai kandungan protein tertinggi dan kandungan mineral yang paling tinggi terdapat dalam C. thevetia.Kata kunci: Analisis proximat, Kera Ekor Panjang, Nutrisi, Buah-buahan Abstract: Proximate analysis of twelve species of fruits commonly consumed by longtailed macaques (Macaca fascicularis), i.e., Arenga pinnata, Areca catechu, Terminalia catappa, Elaeis guineensis, Lagerstroemia tomentosa, Mangifera indica, Cascabela thevetia, Muntingia calabura, Musa sp., Artocarpus heterophyllus, Ficus tinctoria ssp. gibbosa and Ficus microcarpa, was conducted with the specific objective to determine the nutritional composition of the foodstuffs of long-tailed macaques. The results showed the following order of nutrients: fibre, protein, fat and ash. Based on the results of the chemical analysis, the highest percentage of fibre content (52.7%), protein (9.9%), fat (77.2%) and ash (8.5%) were found in A. catechu, T. catappa, E. guineensis and C. thevetia, respectively. The nutrient composition of these twelve fruit species was found to differ (ANOVA test: crude protein, F (11,24) = 87.978, p < 0.05; crude fibre, F (11,24) = 28.886, p < 0.05; crude fat, F (11,24) = 2081.396, p < 0.05 and ash, F (11,24) = 41.011, p < 0.05). Fibre was found in the highest amount among the four types of nutrients studied. Here, A. catechu had the highest relative fibre content of all tested fruits, E. guineensis had the highest fat content, T. catappa had the highest protein content, and the total mineral content was highest in C. thevetia. *
In Malaysia rural area, the fixed-rate method is the waste charging approach adopted by the local authorities because of low administration cost, but it is ineffective and has caused many environmental issues. Therefore, this study was conducted to explore the public willingness to pay on better solid waste management services at rural area of Kelantan. A total of 911 respondents from three (3) districts (Jeli, Kuala Krai, Gua Musang) participated in this study. The results showed that most respondents (±75%) expressed their satisfaction on current solid waste management services provided. This study indicated that nearly 62% of respondents were willing to pay more for better solid waste management services. This study revealed that the estimated mean willingness to pay (WTP) for better solid waste management service is RM12.05 per household. Logistic regression model suggested that satisfaction on solid waste management services affected the WTP amount, apart from socio-economic factors such as educational level, type of houses, occupation and household income. The results can be useful for understanding the rural resident’s attitudes and WTP for solid waste management services.
Globally, rapid urban expansion has caused green spaces in urban areas to decline considerably. In this study, the rapid expansion of three Southeast Asia cities were considered, namely, Kuala Lumpur City, Malaysia; Jakarta, Indonesia; and Metro Manila, Philippines. This study evaluates the changes in spatial and temporal patterns of urban areas and green space structure in the three cities over the last two decades. Land use land cover (LULC) maps of the cities (1988/1989, 1999 and 2014) were developed based on 30-m resolution satellite images. The changes in the landscape and spatial structure were analysed using change detection, landscape metrics and statistical analysis. The percentage of green space in the three cities reduced in size from 45% to 20% with the rapid expansion of urban areas over the 25-year period. In Metro Manila and Jakarta, the proportion of green space converted to urban areas was higher in the initial 1989 to 1999 period than over the latter 1999 to 2014 period. Significant changes in green space structure were observed in Jakarta and Metro Manila. Green space gradually fragmented and became less connected and more unevenly distributed. These changes were not seen in Kuala Lumpur City. Overall, the impact of spatial structure of urban areas and population density on green space is higher in Jakarta and Metro Manila when this is compared to Kuala Lumpur. Thus, the results have the potential to clarify the relative contribution of green space structure especially for cities in Southeast Asia where only a few studies in urban areas have taken place.
Diabetes mellitus (DM) is a metabolic disorder characterized by hyperglycemia and is considered a major health problem in the world. It is associated with endothelial dysfunction which causes progressive vascular damage. DM is a known risk factor for atherosclerosis and cardiovascular complications such as peripheral artery disease, coronary artery disease, and stroke. Medicinal plants may act as an alternative resource or adjunctive treatment option in the treatment of diabetes and its cardiovascular complications. Parkia speciosa (Fabaceae) is a plant found abundantly in the Southeast Asian region. Its seeds, with or without pods, and roots have long been used as a traditional medicine in this region to treat hypertension and diabetes. Studies have shown its numerous beneficial pharmacological properties. Extracts of P. speciosa, particularly from its seeds and empty pods, show the presence of polyphenols. They also exhibit potent antioxidant, hypoglycemic, anti-inflammatory, and antihypertensive properties. Its hypoglycemic properties are reported to be associated with the presence of β-sitosterol, stigmasterol, and stigmat-4-en-3-one. The current review aimed to provide an overview of the current status of P. speciosa, its pharmacological potential, and its phytochemical content in attenuating diabetic vasculopathy. Glycemic status, oxidative stress, inflammation, and hyperlipidemia are known to play pivotal roles in the initiation and severity of diabetic cardiovascular diseases; thus, targeting these factors might be beneficial for preventing and/or treating diabetic vasculopathy.
This work investigates the metals concentration in the tissues of Asian swamp eel, Monopterus albus . Five selected tissues, including liver, gill, bone, skin, and muscle were examined for the concentration of Zn, Cu, Cd, Pb, and Ni. The concentrations of Cd and Pb were found high in the muscle tissues of the eels. Additionally, high amounts of Zn and Cu metals were observed in the liver, whereas the Cd, Pb, and Ni metals were highly detected in gill. The accumulation of Zn, Cu, Cd, Pb, and Ni in both skin and bone of the eel seems to vary between seasons. Low levels of Zn, Cu, and Ni were identified in the muscle tissues of the eels. This study revealed that the concentration of Cd and Pb in the muscle tissues of Asian swamp eels exceeded the permissible limits by the US EPA, suggesting the consumption of the muscle may be hazardous and can severely affect one’s health.
