Hylocereus undatus foliage is believed to contain antioxidants similar its peel. Numerous studies have been conducted determine the total phenolic content (TPC) and antioxidant activity on pulps peels; however, yet be investigated. In this study, peels were extracted using two different solvents namely; chloroform methanol through Folin-Ciocalteu method Diphenyl-1-Ipicrylhydrazyl (DPPH) free radical scavenging assay for TPC activity, respectively. As TPC, results revealed that gave higher in...

The effectiveness of dragon fruit foliage as a natural coagulant for treatment concentrated latex effluent was investigated and compared with ferric sulfate, chemical coagulant. Dragon is round often red‐colored scales‐like texture native to south American countries which also cultivated heavily marketed in southeast Asian countries. Its represents part its overall plant system. Latex one the main byproduct from rubber processing factories Malaysia. Three parameters were oxygen demand (COD),...

Abundant oil palm empty fruit bunches (OPEFB) generated from the mill industry create huge problems for environment and itself. Despite importance of determining amount left in OPEFB, little research that nature has been reported. This study describes content physicochemical characteristics OPEFB fibers, detection attachment on fiber’s surface using sudan red dye, contact angle values, also quality residual oil. The which are normally used as mulch mill, have found to be a rich source...

Background People with type 1 diabetes (T1D) depend on external insulin to regulate their blood glucose level (BGL) within the normoglycemic range between 4.0 7.0 mmol/L. Patients T1D routinely conduct self-monitoring of through finger pricks before injections. An artificial pancreas is an innovative device that mimics function a healthy pancreas. Despite its recent advancement, control algorithms used in are still lagging delivering proper dosage patients T1D. Previous researchers attempted...

Most vegetable oils have high content of unsaturated bond and can be converted into epoxidized fatty acids. These days, are great concern as they obtained from sustainable, renewable natural resources environmental friendly. The epoxidation palm oleic acid was carried out by using in situ generated performic (HCOOOH) to produce acid. degree temperature, the molar ratio formic or hydrogen peroxide types catalyst considered. Epoxidation results were based on complete conversion oxirane, rate...

A characterization study on oil palm decanter cakes (OPDC) was performed to gain an in-depth understanding of the material's characteristics aid in potential residual recovery.The OPDC characterized by a high moisture content, biodegradability, organic and nutrient-rich composition.Microscopic observation showed that attachments OPDC, vast majority droplets, were less than 50 μm size.Furthermore, contact angle measurement revealed hydrophilic oleophilic OPDC.Specifically, angles water crude...

This study focused on the performance of dragon fruit foliage as a natural, plant-based coagulant to replace chemical coagulants for treatment three-phase decanter palm oil mill effluent (POME). Palm is high strength wastewater with oxygen demand (COD), suspended solids (SS), and turbidity compared other sources POME in mills. The first objective this was determine optimum operating conditions coagulation-flocculation process using terms pH dosage. second measure percentage removal COD, SS,...

The discharge of Palm Oil Mill Effluent (POME) to river or sewage has caused serious environmental problems for the past several decades. This prompted many researchers find alternative technologies such as use an ultrasonic-assisted membrane anaerobic system, also known UMAS. However, further UMAS in treating POME tends create blockage on surface, which is commonly fouling. In this study, kinetic parameters samples contributed fouling were investigated, namely; biomass growth rate, μmax and...

Recently, in silico testing which is managed via computer simulation, preferably performed on Diabetes patients rather than to be evaluated directly their body due the benefit of patient safety and accelerated progress obtained from convenient testing. However, it still difficult have an accurate efficient therapy through this simulation method. Therefore, continuous investigation research are necessary so as enhance a reliable treatment future. In work, we propose improved Diabetic model...

Palm oil industry produces huge amount of palm decanter cake (OPDC). Currently it is not yet commercialized however due to its characteristics, can be used produce natural polymer composite (OPDC-NPC). NPC a type material made by combining fiber with polymer. Therefore the objective this paper from OPDC and then determine mechanical physical properties such as elasticity, stiffness, tensile strength water absorption rate. The samples were collected Felda Trolak Oil Mill. Prior development,...

Keeping pace with emerging technologies, artificial pancreas is highly recommended to be used as an alternate way solve blood glucose level problem for Type 1 diabetes patients. It aimed develop embedded nanochip controller in order regulate the within safety range. However, due lack of effectiveness algorithm, patients body still not achieving optimum level. The function which heart device, needs analyzed ensure device can fully utilized. Therefore, system identification technique applied...

The development of palm oil industry in Malaysia has turned into a phenomenum which the area plantation expanded from year to year. In meantime, rapid growth industries additionally caused detrimental effect environment due its downstream and upstream processing activities. early ages, residue production process was burned effluent discharged untreated waterways serious problem environment. Therefore, new technology is sought reduce impact on at same time biogas recovered as an alternative...

Although Malaysia is a model for economic success amongst Southeast Asian countries with its impressive development over the last 36 years, it has not been without detrimental effects on natural environment. The most apparent effect drastic increase in generation of hazardous wastes. This paper highlights Malaysia's current status waste management and potential major difficulties. principles, objectives remedial plans control are also explained detail have stipulated environmental policies...

Artificial pancreas (AP) device consists of continuous subcutaneous insulin infusion (CSII)pump, glucose monitoring (CGM) sensor, CGM receiver amd control algorithm which measure and regulate current blood level (BGL) type 1 diabetes (T1D) patients in automated manner. All components the AP are now well-established readily avaialble market; however, its is still at infant stage. This sometimes leads to insufficient or excessive amounts injected into their body causing hyperglycaemia...

Recently, diabetes is known as one of non-communicable diseases that can lead to fatal if there no further cure be taken especially in South-East Asia regions. An artificial pancreas introduced help patient controls their blood glucose level but the current device not functioning fully automated yet. In order have pancreas, a controller needs improved 33% less accuracy than required. This improvement will Type 1 managing at recommended range. Besides, presence live normally non-diabetes...
