The beta cell
protein synthetic machinery is dedicated to the production of mature insulin,
which requires the proper folding and trafficking of its precursor, proinsulin.
The complete network of proteins that mediate proinsulin folding and
advancement through the secretory pathway,
however, remains poorly defined. Here we used affinity purification and mass
spectrometry to identify for the first time, the proinsulin biosynthetic
interaction network in human islets. Stringent
analysis established a central node of proinsulin interactions with ER folding
factors, including chaperones and oxidoreductases, that is remarkably
conserved in both sexes and across three ethnicities. The
ER-localized peroxiredoxin PRDX4 was
identified as a prominent proinsulin interacting protein. In beta cells, gene
silencing of PRDX4 rendered proinsulin susceptible to misfolding, particularly
in response to oxidative stress, while exogenous PRDX4 improved proinsulin
folding. Moreover, proinsulin misfolding
induced by oxidative stress or high glucose was accompanied by sulfonylation of
PRDX4, a modification known to inactivate peroxiredoxins. Notably, islets from
patients with Type II diabetes (T2D) exhibited significantly higher levels of
sulfonylated PRDX4 than islets from healthy individuals. In conclusion, we have
generated the first reference map of the human
proinsulin interactome to identify critical factors
controlling insulin biosynthesis, beta cell function, and T2D.

Functional and Antioxidant Properties of Angelwing Clam (Phplas orientalis) Hydrolysate Produced using Alcalase
Authors: Ismail Nonnah , Mahmod Juliana , Mustafa Kamal Awatif Khairul Fatihin
Published: May 2020

In this study, Hydrolysate from angelwing clam (Pholas orientalis) was produced at 0, 1, 2 and 3 hrs and E/S ratio of0.5 and 3%using alcalase where the pH and temperature were kept constant at pH 8.5 and 60°C, respectively. The hydrolysates were analysed for antioxidant and functional properties such as solubility, emulsifying properties and water and oil holding capacity. Degree of hydrolysis (DH), yield, functional and antioxidant properties were influenced by the hydrolysis time and E/S ratio. Higher enzyme concentration (E/S 3%) and longer hydrolysis time increased the DH. Yield was higher at E/S 3% but reduced with hydrolysis time. Longer hydrolysis time produced more soluble hydrolysate and higher metal chelating activity but lower in emulsifying properties and DPPH activity. Higher enzyme concentration resulted in increase only in solubility and metal chelating activity. This study revealed that enzymatic hydrolysis using alcalase should be performed at shorter hydrolysis time using intermediate concentration of enzyme (E/S between 0.5 to 3%) in order to produce angelwing clam hydrolysate with collectively good functional and antioxidant properties.

Authors: Wan Din Wan Isni Sofiah , Yahya Saadiah , Taib Mohd Nasir , Mohd Yassin Ahmad Ihsan , Razali Razulaimi
Published: May 2020

Clustering in Wireless Sensor Network (WSN) is one of the methods to minimize the energy usage of sensor network. The design of sensor network itself can prolong the lifetime of network. Cluster head in each cluster is an important part in clustering to ensure the lifetime of each sensor node can be preserved as it acts as an intermediary node between the other sensors. Sensor nodes have the limitation of its battery where the battery is impossible to be replaced once it has been deployed. Thus, this paper presents an improvement of clustering algorithm for two-tier network as we named it as Multi-Tier Algorithm (MAP). For the cluster head selection, fuzzy logic approach has been used which it can minimize the energy usage of sensor nodes hence maximize the network lifetime. MAP clustering approach used in this paper covers the average of 100Mx100M network and involves three parameters that worked together in order to select the cluster head which are residual energy, communication cost and centrality. It is concluded that, MAP dominant the lifetime of WSN compared to LEACH and SEP protocols. For the future work, the stability of this algorithm can be verified in detailed via different data and energy.

Published: May 2020

An investigation on the properties of Tenun Pahang fabric performances using alternative yarns was conducted. The studies were made in order to evaluate whether the Tenun Pahang fabric could be produced economically and at the same time maintain the fabric quality. Traditional Tenun Pahang fabric uses silk for both warp and weft. For this project, two alternative yarns were used which were bamboo and modal, which were a little lower in cost compared to silk. These yarns were woven with two variations, one with the yarns as weft only while maintaining the silk warp and the other with both warp and weft using the alternative yarns. Four (4) physical testings and three (3) mechanical testings conducted on the fabric samples. The fabric samples were evaluated including weight, thickness, thread density, crease recovery angle, stiffness and drapability. The results show that modal/silk and bamboo silk fabrics are comparable in terms of stiffness and drapability, hence they have the potential to replace 100% silk Tenun Pahang.

Published: May 2020

Nowadays, development of cable-stayed bridges is increasing around the world. The mitigation of seismic forces to these bridges are obligatory to prevent damages or failure of its structural members. Herein, this paper aimed to determine the near-fault ground motion effect on an existing cable-stayed bridge equipped with lead-rubber bearing. In this context, Shipshaw cable-stayed bridge is selected as the case study. The selected bridge has a span of 183.2 m composite deck and 43 m height of steel tower. 2D finite element models of the non-isolated and base isolated bridges are modelled by using SAP2000. Three different near-fault ground motions which are Tabas 1978, Cape Mendocino 1992 and Kobe 1995 were subjected to the 2D FEM models in order to determine the seismic behaviour of the bridge. The near-fault ground motions were applied to the bridge in the longitudinal direction. Nonlinear dynamic analysis was performed to determine the dynamic responses of the bridge. Comparison of dynamic response of non-isolated and base isolated bridge under three different near-fault ground motions were conducted. The results obtained from numerical analyses of the bridge showed that the isolation system lengthened the period of bridge and minimised deck displacement, base shear and base moment of the bridge. It is concluded that the isolation system significantly reduced the destructive effects of near-fault ground motions on the bridge.

Published: May 2020

Sewage sludge is a by-product generated within the wastewater treatment process. Severe concern arised as the sludge are massively been dumped to the landfill and it may affect the environment. Many studies had been conducted in reusing the sewage sludge as construction material, where it is one of the optional ways to solve the issue. In this study, dried sewage sludge was incinerated with two different temperatures in order to produce sewage sludge ash (SSA), which are 800°C and 1000°C. After few processes, this SSA then reused in mortar as cement replacement with the replacement percentage of 5%, 10%, 15% and 20% by weight. The strength performance of mortar specimens was investigated after 7, 28, 60 and 90 days of curing. From the results, it is clearly showed that the compressive strength of all mortar specimens increased when the period of curing was prolonged. Moreover, almost all compressive strength of SSA mortars was higher than the control mortar. Therefore, there is potential to reuse this waste material as part of construction materials and hence, its plays an important role for future researches in minimisation of waste.

Authors: Mohamad Rosman Mohamad Rahimi , Abdul Aziz Mohammad Azhan
Published: May 2020

Content management is an organisational effort of managing content, particularly in digital format. Although it has been over 25 years since content management was introduced, this field of study is still considered an emerging topic with unresolved issues-in particular, the subject of benefit achievement. Therefore, grounded on an extensive review of 135 articles, the purpose of this study is to investigate the benefits that organisations can gain through the proper use of an Enterprise Content Management System (ECMS). Subsequently, this paper identifies a list of ECMS benefits and proposes an ECMS benefit framework for further exploration into this field. Our result shows that although ECMS does bring benefits to organisations, these benefits are diverse; indicating that there are certain determinants or factors influencing the achievement of such benefits. Moreover, it is also found that in the context of the benefit framework of Shang and Seddon [10], three categories were found relevant to the field of content management: operational benefit, managerial benefit, and strategic benefit.

The purpose of this study was to investigate the effect of papaya leaves crude extract on the physicochemical properties of marinated chicken meat. Papaya leaves was extracted with sodium acetate (CH3COONa) buffer (pH 7.2) at room temperature. Protein concentration and activity of enzyme in the crude extract were determined by using UV-Spectrophotometer. The crude extract was mixed with marinated ingredients and then coated onto chicken meat which was subsequently kept for overnight in refrigerator at chill temperature. Protein concentration of the enzyme was identified as 166.36 μg/μl and enzyme activity was 1.28 CDU/ml. Results also showed that lightness (L*), cooking loss and shrinkage of the marinated chicken were higher than control. Redness (a*), yellowness (b*), protein content, water-holding capacity, shear force, and texture profile analysis were lower than control. Microstructure analysis showed that the chicken meat muscle was destructed in the presence of papaya crude extract. Sensory acceptability evaluation of marinated chicken which was carried out by using 9 point hedonic scale suggested that chicken meat treated with papaya crude extract gave significant effect on texture, juiciness, flavour and overall acceptability compared to commercial bromelain. Additionally, the use of papaya crude extract gave a significant effect on the physicochemical properties of marinated chicken.

Authors: Mohd Ridzuan Ahmad Ruslan , Ibrahim Azmi , Mohd Ismail Abdul Manaff
Published: May 2020

The effects of using crushed waste concrete as course aggregates upon compressive strength and carbonation were investigated. Waste concrete cubes, which had been tested for compressive strength in compliance with construction specification, were crushed and utilized as coarse recycled aggregates in new concrete. It is important to mention that, in order to simulate the real life conditions, waste concrete with very minimal information about its originality was used in its natural moisture condition. Tests on the aggregates showed that the recycled concrete aggregates have lower specific gravity and bulk density but have higher water absorption capacity than the natural aggregates. The resistance to mechanical actions such as impact and crushing for recycled concrete aggregates is also lower. Concrete mixes with design strength of 30 N/mm2, 35 N/mm2 and 40 N/mm2 were prepared using this recycled aggregates as coarse aggregates and tested. From the strength point of view the recycled aggregate concrete compared well with natural aggregate concrete. Therefore, it could be considered for various potential applications. With respect to resistance to carbonation the recycled aggregate concrete shows comparable performance.

Authors: Alwadood Zuraida , Ayub Hamidah , Razali Muhamad Ariff Izuddin
Published: May 2020

This paper analyzes the problem faced by a cleaning service company, which records and pays out a large amount of overtime each month. With only one shift per day, the labor force is required to work overtime in order to satisfy the daily work demand The objective of this paper is to determine the optimum schedule to satisfy the labor requirements at a minimum cost. Tiberwala et al. s (1972) single-shift integer programming model for scheduling workers with two consecutive days off per week has been used as the starting point for this research. This paper modifies the model to incorporate two and three shift schedules with one day off per week. Three alternative workforce schedules are then compared and evaluated. The first alternative maintains the traditional one-shift schedule, currently being practiced by the company. The second and third alternatives switch to a two-shift schedule and three-shift schedule, respectively, with overlapping working hours linking the shifts. In comparison to the existing one-shift schedule, the three-shift schedule is expected to produce savings of 21.4 per cent equivalent to RM 23,592 annually.

Authors: Raja Yahya Mohd Fakharul Zaman , Mohd Sidek Hasidah
Published: May 2020

Malaria parasites, Plasmodium can infect a wide range of hosts including humans and rodents. There are two copies of mitogen activated protein kinases (MAPKs) in Plasmodium, namely MAPK1 and MAPK2. The MAPKs have been studied extensively in the human Plasmodium, P. falciparum. However, the MAPKs from other Plasmodium species have not been characterized and it is therefore the premise of presented study to characterize the MAPKs from other Plasmodium species-P. vivax, P. knowlesi, P. berghei, P. chabaudi and P.yoelli using a series of publicly available bioinformatic tools. In silico data indicates that all Plasmodium MAPKs are nuclear-localized and contain both a nuclear localization signal (NLS) and a Leucine-rich nuclear export signal (NES). The activation motifs of TDY and TSH were found to be fully conserved in Plasmodium MAPK1 and MAPK2, respectively. The detailed manual inspection of a multiple sequence alignment (MSA) construct revealed a total of 17 amino acid stack patterns comprising of different amino acids present in MAPKJ and MAPK2 respectively, with respect to rodent and human Plasmodia. It is proposed that these amino acid stack patterns may be useful in explaining the disparity between rodent and human Plasmodium MAPKs.

Published: May 2020

Cyclic guanosine monophosphate (cGMP) is a second messenger molecule involved in the intracellular signalling mechanism which is important in a wide range of cellular process including metabolism, gene expression, cell proliferation and cell death. This study was conducted to determine the effect of fresh carotino oil (FCO) and thermoxidized carotino oil (TCO) on erythrocyte cGMP levels .fi·om Sprague Dawley rats. A total of 30 Sprague dawley rats were randomly segregated into three groups: the first o.f which was placed on a Fresh Carotino Oil (FCO) diet, the second on a Thermoxidized Carotino Oil (TCO) diet and the control group on commercial rat chow on(v for a period of 6 and 9 weeks. The two oil diets comprised o.f 20% (w:w) of each oil mixed with commercial rat.feed. The enzyme immunoassays, performed in week 6, revealed that the erythrocytes cG MP levels for the FCO and TCO groups were 66.198±3.193 pmol/ml and 61.990±6.318 pmol/ml respectively, and were significant (p<0.05) lower than the value .for the control group, 77.978±10.479 pmol/ml. The assays performed in week 9 revealed the erythrocytes cG MP levels for the FCO and TCO groups to be 66.522±8.194 pmol/ml and 56.842±8.546 pmol/ml respectively which were also significantly (p<0.05) lower than that for the control group, 82.817±6.677 pmol/mL. The results indicate that the presence o.l antioxidants, such as beta-carotene and tocols in carotino oil may modulate cG MP levels in rats.
Electrical Resistivity, Thermal Stability and Tensile Strength of Rice Husk Flour-Plastic Waste Composites
Authors: Bahari Shahril Anuar , Kamlon Kamrie , Abu Kassim Masitah
Published: May 2020

In this study, the rice husk flour-plastic waste composites (RPC) was produced from polypropylene (PP) and high density polyethylene (HDPE) wastes with 30 and 50% rice husk flour (RHF) contents. RPC was made by melt compounding and compression moulding processes. The electrical resistivity, thermal stability and tensile strength of RPC were determined. The RPC was tested in electrical resistivity and tensile strength according to the ASTM D-257 and ASTM D-638 respectively, while thermal stability was tested using thermogravimetric analysis (TGA) method. From the results, high content of RHF reduces all properties, except for tensile modulus of elasticity (TMOE) in tensile strength test. The ability of moisture absorption and the presence of hemicelluloses, cellulose and silica in RHF reduce the electrical resistivity and thermal stability behaviour of RPC from 50% RHF. The good binding elements and filler agglomeration in RPC from 50% RHF improve only TMOE. Insufficient stress transfer and rigid interphase occurred between RHF and plastics during tensile maximum load and elongation at break (Eb) in tensile strength test. In general, RPC from HOPE indicates better thermal stability, tensile modulus of rupture and E (in tensile strength test) compared to PP, based on the good behaviour of thermal conductivity, low water absorption, high molecular weight and good elongation properties of HDPE. However, RPC from PP shows good electrical resistance due to the low thermal expansion coefficient of PP.

Indonesia adalah salah satu negara yang masyarakatnya banyak mempelajari bahasa Mandarin, tetapi kajian tentang bahasa Mandarin maupun pengajaran Mandarin masih sedikit. Untuk itu peneliti merasa perlu melakukan beberapa kajian dalam bidang kebahasaan dan pembelajaran bahasa Mandarin dengan jenis studi eksploratif dan deskriptif. Penelitian ini secara umum dirumuskan berdasarkan masalah atau kesulitan huruf konsonan (z, c, s, zh, ch, sh, r) bahasa Mandarin yang muncul pada mahasiswa angkatan 2017 prodi D4 Bahasa dan Budaya Tiongkok FIB Unpad. Penelitian ini menggunakan metode deskriptif kualitatif dan analisis, dilakukan dengan tujuan untuk mengetahui kesalahan atau kesulitan bunyi pelafalan apa saja yang muncul saat mahasiswa melafalkan bunyi konsonan (z, c, s, zh, ch, sh, r), kemudian menganalisa dan menyimpulkan penyebab atau hal yang melatarbelakangi munculnya kesalahan pelafalan tersebut. Dari hasil rekaman 19 mahasiswa angkatan 2017 yang ditranskripkan dan dari hasil analisis secara umum, sebagian besar mahasiswa melakukan kesalahan pada bunyi konsonan (z), (c), (zh), dan (ch). Kesalahan dalam melafalkan bunyi ini, selain disebabkan karena faktor interferensi, perbedaan bentuk grafem/tulisan juga menjadi penyebab kesalahan dalam pelafalannya dan termasuk kesalahan intralingual pula.
Rekonstruksi Font Aksara Sunda Unicode: sebuah Alternatif Perbaikan Font Aksara Sunda

Published: May 2020

Kreativitas dalam pengembangan berbagai hal berbasis komputer tidak hanya berlaku pada wilayah-wilayah kehidupan primer (utama) tetapi merambah juga ke wilayah-wilayah sekunder seperti bidang bahasa daerah. Bahasa daerah yang saat ini keberadaannya terus tersisihkan oleh para pencintanya terus dikembangkan salah satunya dengan memanfaatkan Information and Comunication Technology (ICT). Wujud nyata dari usaha tersebut di antaranya dengan dibuatnya beberapa font aksara daerah, seperti font aksara Sunda. Kemunculan font aksara Sunda ini sangat penting bagi perkembangan bahasa Sunda karena pada dasarnya aksara daerah merupakan alat rekam yang tepat  bagi bahasa daerah tersebut (Baidilah dkk., 2008). Hampir di setiap wilayah di Jawa Barat aksara Sunda dapat ditemui pada nama-nama jalan, instansi, ataupun produk-produk kreatif. Kemunculan aksara Sunda di berbagai media tersebut tentunya tidak lepas dari peran font aksara Sunda Unicode (IB80-IBBF) yang mempermudah masyarakat dalam menulis aksara Sunda. Dengan font aksara Sunda, menulis aksara Sunda yang sebelumnya hanya digunakan pada naskah-naskah kuno kini bisa diterapkan pada berbagai media yang berbasis komputer. Font aksara Sunda yang dirintis sejak 2005 saat ini teridentifikasi mengalami beberapa masalah. Salah satu masalah yang ditemukan adalah adanya kesalahan ejaan pada hasil pengetikan yang menggunakan font aksara Sunda. Kesalahan tersebut terindentifikasi karena adanya perbedaan sifat aksara Sunda (bersifat silabik) dengan aksara Latin (bersifat fonetis) yang menjadi basis dalam font komputer.
