The rate of new saloons in Rivers State is alarming and the conditions with which the operators carryout their activities, calls for public health concern. Hence, the prevalence and antibiogram of bacterial isolates from barbing saloon equipment in barber shops located in Bori, Omoku, and Port Harcourt in Rivers State was investigated using standard microbiological techniques. Samples for analysis were collected by swabbing the surfaces of clippers, brushes, and combs using moist swab sticks. The total heterotrophic bacteria and Staphylococci were evaluated using nutrient and mannitol salt agar respectively. The Kirby Bauer disc diffusion method was used to determine the susceptibility pattern of the isolates. The mean heterotrophic bacterial counts ranged from 17.62±2.75x103 to 40.95±14.49x103CFU/cm2, the total Staphylococcal count ranged from 11.67±1.29x102 to 39.69±20.61 x102CFU/cm2. A total number of 77 isolates belonging to six genera were isolated and they include; Acinetobacter baumannii (2.59%), Arthrobacter mysorens (16.88%), Bacillus cereus (20.78%), Micrococcus luteus (12.99%), Serratia marcescens (9.1%), Staphylococcus aureus (37.66%). The prevalence of these organisms was more on the brush with a mean of 2.68 compared to clipper and comb with means of 1.63 and 0.5, respectively. Statistical analysis showed no significant difference among the Port Harcourt isolates but showed a significant difference for Bori and Omoku isolates at p≤0.05. The susceptibility pattern showed Staphylococcus aureus was resistant to Ofloxacin, Levofloxacin, Cephaflash and Cotrimoxazole while Bacillus cereus and Arthrobacter mysorens were susceptible to all eight antibiotics. The pattern of occurrence on different equipment suggests that less attention is usually given to brush in these establishments. Regulatory policies to check the activities of these saloons to prevent an outbreak of disease is advocated

The distribution and susceptibility pattern of fungal isolates from barbing equipment to Fluconazlole in barber shops distributed in three major cities; Bori, Omoku, and Port Harcourt in Rivers State, Nigeria were investigated. The fungal load including dermatophytes on the equipment (brush, clipper and comb) were determined using swab plate technique in which Sabouraud dextrose agar and dermatophyte test medium were used as the culture medium. Inoculated plates were incubated at 25°C. Antifungal Susceptibility testing was carried in which fluconazole was used as the antifungal agent at concentrations of 100mg/ml, 50mg/ml, 25mg/ml, and 12.5mg/ml concentration using two-fold dilution. The mean range of the fungal counts for clipper, brush and comb were: 34.34x102 to 49.0x102 CFU/cm2, 66.95 to 93.26 CFU/cm2 and 40.09 to 74.61 x102 CFU/cm2, respectively. Brush had the highest fungal counts followed by the comb while the clipper had the least fungal counts. The fungal counts recorded in brushes were significantly higher (p≥0.05) than those recorded for the clippers. Total of forty-four fungal isolates belonging to six genera and their percentage occurrence include; Aspergillus flavus (11.36%) Aspergillus terrus (11.36%), Fusarium solani (22.72%), Mucor indicus (15.91%), Rhizopus nigricans (15.91%), Trichophyton rubrum (4.54%) and Penicillium italicum (18.2%). The susceptibility pattern showed that except for Trichophyton rubrum, all fungal isolates were completely inhibited at 100mg/ml concentration of fluconazole. Also, except for Mucor indicus, the Minimal inhibitory Concentration of fluconazole was recorded at 12.5mg/ml. The occurrence of these organisms in barbing equipment calls for concern and the need for regulation of the barbing industry to prevent disease outbreaks is recommended.

Published: July 2022

Inflation is the most common fact of our time, the single greatest peril to our economic health. Prices of various goods and services have been rising at a very high rate. In the past few years companies have reported very high profits on the one hand but on the other hand, they have faced real financial difficulties. This is so because in reality dividends and taxes have been paid out of capital due to overstated figures of profits arrived at by adopting historical cost concept. This has led to the collapse of many businesses. Money is a measure of value and value changes from time to time so money is a function of value change. The value of a business is its earnings per share (share price). Changing value of' money has resulted in a chaos and distortion while reporting results of economic activities of business enterprises in the manufacturing firms in Nigeria. This study aimed at reviewing the accounting for inflation and current price financial reporting of manufacturing firms in Nigeria. Extant literature was reviewed and analyzed. Findings suggested that changing price level, otherwise called inflation, has a significant effect on current price financial reports of listed manufacturing firms in Nigeria. Thus, recommends that manufacturing firms should report financial statements on the basis of current prices in order to give a more realistic information of their performances.

The study examined the impact of taxation on the performance of manufacturing company in Nigeria from 2005-2021. The study sought to determine if taxation has any impact on the return on asset (ROA) and earnings per share (EPS) using flour mills plc as a case study. The Ex-post research design was adopted and time series data were collected for the study. The ordinary least square regression analysis was used in the analysis. The findings revealed that there is no significant relationship between taxation and the performance of manufacturing company in Nigeria. From the result of the analysis, independent variable of tax showed a weak and negative relationship with ROA and weak and positive relationship with EPS. The study recommends that there should be improvement in the effectiveness of tax administration by ensuring proper assessment. Also, all Relevant Tax Authorities (ROA) should endeavour to have good relationship with the Professional Associations like Chartered Institute of Taxation of Nigeria (CITN) and Institute of Chartered Accountants of Nigeria (ICAN) involved in tax matters so as to increase their support in reducing tax malpractices perpetrated by tax payers with the connivance and often active support of external auditors and tax consultants. Also, the entire tax system as well as the taxes that affect the performance of manufacturing sectors should urgently be overhauled for more effectiveness to achieve the desired results.

The study examined the influence of firm complexity on tax aggressiveness of Listed Deposit Money Banks in Nigeria and South Africa. The study employed the longitudinal research design in a cross-country comparative analysis approach. The sample size consists of an equal sample of the 13 listed deposit money banks quoted on the Nigerian Exchange Group (NGX) and 13 listed deposit money banks quoted on the Johannesburg Stock Exchange, South Africa. Secondary data was used for the study as extracted from the annual reports and financial statements of the selected banks for a nine-year period of 2012-2020. The panel data were analyzed using a descriptive statistic, correlation and panel data regression technique which was dually estimated to capture the samples of both countries. The outcome of the Nigerian model showed that firm complexity asserted significant negative impacts on tax aggressiveness in Nigeria, and in model ii, it showed that firm complexity has an insignificant negative impact on tax aggressiveness in South Africa. The study recommends, among others, that the notion that highly diversified banks engaged in less tax aggression was upheld in the Nigerian sample. Since most diversified Nigerian companies had subsidiaries and cross-border affiliations with South Africa, there is a need for both governments to simplify the tax laws and focus more on creating a tax culture in order to foster voluntary compliance among multinationals.

Citizen journalism has transformed the face of journalism practice in Nigeria and the rest of the world. The Internet has basically restructured the mode of news and information gathering and distribution. Unfortunately, not complying by the ethics of the profession has become its main challenge, a circumstance that is put down on some identified factors. Today, there is no distinct difference between the function of conventional journalism and citizen journalism. Conventional journalism, which is the established career of journalism, calls for different kinds of trainings, which could be through education or apprenticeship, for them to carry out their social responsibility function. This is a contrast in the case of citizen journalism, which is currently assuming the role of conventional journalism. This situation foretells undesirable effects to the journalism profession and has equally contributed to the rise of security challenges around the country. Situated within the framework of Source Credibility Theory, this study was designed as a survey. The population of study were residents of Awka metropolis from which a sample size was selected. Finding shows that major issues associated with the credibility of citizen journalism are issues of ethics, professionalism, and training which pose a security threat to the stability of the country. The study recommends that these challenges require to be crucially addressed before they cause mayhem and chaos in the country

Published: July 2022

Bioeconomic modelling is an important issue in sustainable fisheries management of commercial marine fisheries in Kelantan, Malaysia. Previous studies focus on the impact of trawling on fisheries, tourism and the socio-environment, which overfishing is a direct threat to local fishing communities. In addition, bottom trawl fishing may affect fishing, environment and socio-economic management objectives. Moreover, fishing activities lead to changes in the structure of marine habitats and affect the diversity, composition, biomass and productivity of related biota. Finally, the previous research discussed on challenges of the fisheries industry in peninsular Malaysia. Studies focused on bioeconomic modelling in sustainable management of commercial marine fisheries in terms of fishing gear, climate changes, and anthropogenic disturbances are still limited. This study aims to investigate the sustainability of marine fish production and analyse the potential effect of climate changes and anthropogenic disturbances that affect fisheries activities. The theory and practice of the bioeconomic surplus production model by Gordon - Schafer (GS) are used to calculate the total biology and economic value. The result of the study indicated that trawl nets, anchovy purse seinses, climate changes and anthropogenic disturbances affect the sustainable management of commercial marine fisheries in Kelantan, Malaysia.

Authors: Wisittipanich Warisa , Boonmee Chawis , Khwanngern Krit , Chattinnawat Wichai
Published: July 2022

This research proposes a mathematical model for multi-period surgical scheduling problem with capacity constraint over a particular time horizon. The goal is to schedule a list of patients who must undergo various kinds of operations by different eligible hospitals. In particular, each operation must be performed in a particular time period and different operations of one patient can be performed by different eligible hospitals. In addition, each hospital has limited surgery capacity for each time period. The problem is formulated with a multi-objective model using the weighted sum approach of two objectives: minimization of makespan and minimization of total least preference assignment score. The experiment is executed using the simulated data according to the real treatments of cleft lip and palate patients. The results show that the model yield the correct assignment and operation sequence respected to all constraints. Thus, this proposed mathematical model can be further used as smart decision tool in surgical scheduling in hospital network.

Kalsium karbonat (CaCO3) merupakan mineral yang melimpah dari alam dan penting bagi dunia industri, seperti kertas, plastik, dan cat. CaCO3 memiliki tiga fase yaitu: kalsit, aragonite, dan vaterite [1]. Karakteristik dari tiga jenis fase kristal CaCO3, yaitu: kalsit dengan morfologi rombik (kotak miring), aragonite dengan morfologi jarum, dan vaterit dengan morfologi speroid berpori[3]. Dalam penelitian ini dilakukan eksperimen tentang pertumbuhan kristal CaCO3 dengan mereaksikan CaCl2 dan Na2CO3 dengan variasi laju alir 5 ml/menit, 10 ml/menit, dan 17 ml/menit dengan penambahan zat aditif berupa asam malonat (C3H4O4) 20 ppm, dan asam sitrat (C6H8O7) 20 ppm ke dalam larutan berpengaduk. Hasil yang didapat yaitu semakin cepat penambahan Na2CO3 tanpa maupun dengan asam malonat dan asam sitrat maka semakin banyak pula massa kristal CaCO3 yang diperoleh. Dari hasil mikroskop dengan penambahan zat aditif berpengaruh terhadap bentuk kristal CaCO3, asam malonat menyebabkan sedikit perubahan bentuk dari calcite ke bentuk vaterite, sedangkan dengan penambahan asam sitrat menghambat pertumbuhn kristal CaCO3

Mesin penggoreng hampa (Vacuum Fryer) adalah mesin produksi untuk menggoreng berbagai macam buah dan sayuran dengan cara penggorengan hampa. Pada daging dan kulit buah semangka ditemukan zat citrulline. Zat citrulline lebih banyak ditemukan pada kulit semangka yaitu sekitar 60% dibanding di dalam daging semangka yang hanya sekitar 40% saja. Zat citrulline akan bereaksi dengan enzim tubuh ketika dikonsumsi dalam jumlah yang cukup lalu diubah menjadi arginin, asam amino non essensial yang berkhasiat bagi jantung, sistem peredaran darah, dan kekebalan tubuh. Dari sembilan kali percobaan yang telah dilakukan dengan perlakuan suhu berbeda, yaitu 75˚ celcius, 80˚ celcius, dan 85˚ celcius serta waktu penggorengan 40 menit,50 menit,dan 60 menit didapatkan hasil keripik nangka yang memiliki kadar rendemen berbeda- beda. Temperatur paling optimal pada saat melakukan proses penggorengan dengan alat penggorengan vakum adalah 75˚ celcius dengan waktu penggorengan selama 40 menit dengan kadar senyawa Citrulline yang didapatkan sebanyak 3,1 gram per 100 gram kulit buah semangka.

Abstrak

Bioplastik merupakan teknologi kemasan yang terus dikembangkan untuk mengganti plastik sintesis yang  bersifat non – biodegradable. Polivinil alkohol (PVA) adalah salah satu bahan baku yang biasa digunakan dalam pembuatan bioplastik, sebab PVA memiliki sifat dapat membentuk film yang baik, tidak beracun, biodegradable, dan biokompatibel. Akan tetapi PVA memiliki kelemahan bersifat hidrofilik sehingga ketahanan terhadap air rendah. Oleh karena itu pada penelitian ini dikaji penggunaan PVA dalam pembuatan bioplastik pati jagung terhadap ketahanan air, biodegradasi serta morfologi bioplastik pati jagung. Penelitian ini menggunakan Rancangan Acak Lengkap dengan variabel berat PVA yang ditambahkan (0; 1; 1,5; 2; 2,5; 3 gram) dan suhu pelarutan PVA (60oC; 70oC; 80oC). Dari hasil penelitian didapatkan bahwa jumlah penambahan PVA dan suhu pelarutan PVA mempengaruhi ketahanan bioplastik. Berdasarkan hasil penelitian, diperoleh ketahanan air terbaik yaitu 50% pada penambahan 2 gram PVA dan suhu pelarutan 70oC, biodegradasi terbaik selama 5 hari pada penambahan ≤2 gram PVA dengan suhu pelarutan 70oC dan morfologi terbaik pada penambahan ≥ 2,5 gram PVA dengan suhu pelarutan 70oC . Sehingga dari penelitian ini dapat disarankan untuk penggunaan PVA dalam pembuatan bioplastik yang memiliki kandungan amilopektin tinggi maksimal 2 gram dengan suhu pelarutan 70oC

Limbah kulih jeruk bali belum dimanfaatkan dengan baik, sehingga hal ini menjadi fokus untuk dilakukan pengolahan selanjutnya. Kulit jeruk bali mengandung pektin dalam konsentrasi tinggi. Dalam penelitian ini pektin diambil dengan cara ekstraksi agar terjadi perubahan senyawa pektin yang disebabkan oleh proses hidrolisis protopektin menggunakan pelarut/solven asam, solven yang dipilih adalah HCl. Dalam melakukan penetapan variabel, ada variabel tetap dan variabel berubah yang bertujuan untuk mengetahui variabel yang paling berpengaruh dan kondisi optimum pengambilan pektin dari kulit jeruk bali dengan cara ekstraksi. Pektin yang dihasilkan dari ekstraksi ini diharapkan dapat memenuhi standar IPPA (International Pectin Producers Association). Percobaan dilakukan dengan menggunakan kulit jeruk bali yang sudah kering dan berbentuk serbuk berukuran 50 mesh, kemudian menambahkan solven HCl sesuai rancangan percobaan. Larutan hasil ekstraksi kemudian disaring untuk memisahkan ampas dan filtrat. Filtrat kemudian ditambahkan ethanol. Setelah tercampur merata, filtrat didiamkan hingga terbentuk endapan, kemudian disaring dan dikeringkan dalam oven. Pektin kering ditimbang beratnya dan dianalisis kadar metoksil dan galakturonatnya. Hasil penelitian ini menunjukan bahwa variabel yang paling berpengaruh adalah suhu, dengan kondisi optimum pada suhu 80oC, konsentrasi solven HCl 0,2 N dan waktu ekstraksi adalah 120 menit menghasilkan presentase yield sebesar 96,88%. Hasil analisa pektin dari penelitian ini yaitu kadar metoksilnya 4,39% dan kadar galakturonatnya 44% sehingga pektin yang dihasilkan dari penelitian ini sesuai dengan standar mutu IPPA.

Biodiesel merupakan bahan bakar alternative pengganti minyak diesel berbasis fosil. Salah satu tumbuhan yang dapat dijadikan bahan baku pembuatan biodiesel adalah ampas kelapa. Kandungan minyak di dalam ampas kelapa berkisar 12,2-15,9% sehingga merupakan potensi yang besar untuk digunakan sebagai bahan baku pembuatan biodiesel.  Pemanfaatan ampas kelapa selama ini sebagian besar untuk pakan ternak. Pemanfaatan limbah kelapa untuk pembuatan biodiesel diharapkan dapat meningkatkan nilai ekonomisnya. Proses produksi biodiesel dilakukan dengan transesterifikasi in-situ menggunakan methanol sebagai pelarut dan kalium hidroksida sebagai katalis. Dalam penelitian ini bertujuan untuk menentukan variabel yang paling berpengaruh dan kondisi maksimal. Hasil penelitian menunjukkan bahwa rendemen biodiesel tertinggi adalah sebesar 97,03% dengan variabel yang paling berpengaruh adalah konsentrasi katalis dan hasil kondisi terbaik pada konsentrasi katalis 2%,waktu transesterifikasi in-situ 7 jam dan suhu transesterifikasi in-situ 600C. hasil pengujian mutu bodiesel dari hasil penelitian ini adalah densitas874 kg/m3, angka asam 1,9 mg-KOH/gr dan viskositas kinematic 2,9 mm2/s. Hasil tersebut belum memenuhi standar mutu nasional yang ditetapkan untuk bahan bakar biodiesel.
