NURSESâ€™ PERCEPTIONS ABOUT THE IMPLEMENTATION OF FOCUSED ANTE- NATAL CARE SERVICES IN DAR ES SALAAM, TANZANIA
Authors: Yengo M L , Monareng Lydia , Monama E N 
Published: January 2018

A number of countries in Africa, including Tanzania, introduced focused antenatal care (FANC) as an approach to improve the maternal and child health care services and decrease the high rate of maternal deaths. The purpose of this study was to determine the perceptions of nurses with regard to the implementation of FANC in practice. Â A quantitative descriptive design was used to determine how the implementation of FANC guidelines was perceived by nurses who provided midwifery services in Tanzania. Â A questionnaire was used to collect data. Â Stratified random sampling was used to recruit 143 nurses, comprising nursing officers (n=50), midwives (n=53), and public health nurses (n=40). Â The SAS/Basic and SAS/STAT version 11.1 statistical analysis programs were used to analyse data and compile descriptive statistics. Cronbachâ€™s co-efficient reliability was 0.86. Â The results revealed that the greatest area of concern (73.8%; n=104) was the shortage of human and material resources for the successful implementation of FANC. However, there was a positive perception about the implementation and the outcome of FANC services by 98.6% (n=141) of the respondents. Â Authorities and management of these services should attend to and review the human and non-human resource allocation budgets.

Berbagai macam neoplasia telah dilaporkan di prosimian tetapi masih sedikit sekali kasus tumor kulit pada kukang yang dilaporkan. Tulisan ini bertujuan untuk membahas kasus multiple trichoepithelioma pada kukang sumatra (N. coucang). Seekor kukang sumatera berjenis kelamin jantan, dewasa, memiliki berat 670 gram, telah diterima oleh Pusat Rehabilitasi Primata Yayasan Inisiasi Alam Rehabilitasi Indonesia (PRP-YIARI), Bogor pada Mei 2014. Pada pemeriksaan fisik ditemukan sebanyak 18 buah bentukan masa di kulitnya dengan diameter yang bervariasi 5-25 mm dan tersebar di seluruh tubuh mulai dari kaki, tangan, punggung, perut dan dahi. Hasil biopsi jaringan menunjukkan adenoma kelenjar sebaseous dan pemeriksaan histopatologi lanjutan menunjukkan trichoepithelioma. Merujuk dari hasil histopatologi dan keberadaan jumlah tumor yang banyak, maka diagnosa dari kasus ini adalah multiple trichoepithelioma dengan prognosa fausta. Terapi berupa eksisi tumor dengan pembedahan telah dilakukan dan cukup efektif. Masih belum diketahui apakah penyakit ini telah ada pada kukang sejak hidup liar di alam atau terjadi ketika dipelihara dalam lingkungan captive.Kata kunci: kukang, IAR Indonesia, multipel trichoepithelioma, neoplasia (Multiple Trichoepithelioma pada Kukang (Nycticebus coucang) Jantan di Yayasan Inisiasi Alam Rehabilitasi Indonesia: Studi Kasus)A variety of neoplasia have been reported in prosimians, but only a few skin neoplasia were reported in slow lorises. The objective of this case study is to report a case of multiple trichoepithelioma on sumatran slow loris (N. coucang). On May 2014, Pusat Rehabilitasi Primata Yayasan Inisiasi Alam Rehabilitasi Indonesia (PRP-YIARI), Bogor, has been rescued an adult male Sumatran slow loris with 670 gram of body weight. During the physical examination, he was found with 18 masses in his skin, in varies diameter (5-25 mm) and spread in his whole body from hand, foot, back, stomach and forehead. The result of tissues biopsy shown that the masses were sebaceous gland adenoma, but further histopathological examination shown that it was trichoepithelioma. Due regard of the histopathological result and the amount of the tumour, we diagnosed this case study as multiple trichoepithelioma with good prognosis. Treatment by surgical tumour excision has already done and had quite effective result. It still remind unclear whether this case happen since the slow loris live in the wild or during in captivity.Keywords: slow loris, IAR Indonesia, multiple trichoepithelioma, neoplasia

Numerous complex methods have been developed for the preparation of carbon nanotubes (CNT) such as laser vaporization, arc discharge, pyrolysis, and chemical vapour deposition (CVD). In this study, an environmentally friendly and convenient method called one-step water assisted (quenching) synthesis method was conducted from graphite flakes, which were taken from coconut shell wastes to produce carbon nanotubes. Chemical and physical structure of the carbon nanotubes were characterized by FTIR (Fourier Transform Infrared), Scanning Electron Microscope (SEM), and Transmission Electron Microscopy (TEM). Adsorption performance of heavy metals Pb(II) ions by CNTs has been evaluated using the stirring method, and the concentration of Pb(II) ions has been determined using Atomic Absorption Spectroscopy (AAS). The adsorption conditions such as pH and contact time have been obtained. The results showed that carbon nanotubes were a bit successfully formed, in which the tubes distribution are scattered irregularly. The average tube diameter was 123 nm. During the adsorption test, it was found that the adsorption was proportional to the contact time, in which the optimum contact time was 20 minutes. The optimum pH of Pb(II) ions absorption was 5 where the potential for Pb(II) ions absorption was 120 %. The results indicate the true potential of this green chemistry based method, and it opens the chance for possibility to produce carbon nanotubes at a larger scale.

However, the potential resources are not yet fully developed, and only 1.4 GW electrical energy has been generating in the Indonesia region. Most of the wind energy generating equipment is designed to the European wind speed which is 10 - 30 knot. So, it is very important to modify the such equipment to be able to implement in Indonesia area which is have a lower wind speed.The purpose of this research is to know the influence of number of blades and wind speed to electricity generated by horizontal axis wind turbine with blade taper inversed linear.The result showed that the highest electrical output power was 2,02 watt produced by 5 blades and 3,5 m/s wind speed.

Energy crisis in the world especially from fossil fuels which caused by the depletion of non-renewable petroleum reserves. It is therefore necessary to find sources of alternative fuels that are renewable. Biomass is a solid waste that can be used as a fuels source. Peanuts shell and cobs are biomass from agricultural waste which is quite abundant so it is potential to be used as a source of alternative fuels.In this study, peanuts shell biomass combined with charcoal cobs to be made into briquettes by varying the percentage composition of peanuts shell biomass and charcoal cobs as follows 75 : 25, 50 : 50, and 25 : 75. Briquettes that have been printed and then tested its characteristic include heating value, moisture content and ash content.The results show that as the increasing percentage of the charcoal cobs have a significant influence on the characteristic of the briquettes. Briquettes with mix KKT 25 : ATJ 75 has an higher heating value (HHV) and lower heating value (LHV) the highest is equal to 28.718 kJ/kg and 28.279 kJ/kg, and the lowest percentage of moisture content is equal to 5.854%, but the highest result percentage of ash content is equal to 9.326%. Based on the test of these characteristic, biomass briquettes peanuts shell - charcoal cobs meet quality standards that have been established and eligible to became a source of alternative fuels.

Human dependence on fossil fuels cause the reserves of energy resources is increasingly reduced. To overcome these problems is urgently needed alternative fuels which are cheap and readily available, one alternative fuel is biogas. However, the use of biogas not yet maximized because of low heating value of the biogas produced from the process without purification. Premium fueled vehicle proved to be turned on using biogas. Tests conducted on the variation of the engine rotation of 1500, 2500, 3500, and 4500 rpm and variations of biogas that has been purified using the paste pumice stone with a variation of the flow rate of purification of 2 liters / minute, 6 liter / minute, and 10 liters / minute. In this test should be able to get the best performance in terms of fineness engine rotation (force braking and fuel consumption). From the test results with the variation of rotation and flow rate variations purification of biogas obtained performance of the motor fuel of the best on rotation 4500 rpm with a flow rate of fuel biogas purification of 2 liters / minute produces a torque value of 6.98 Nm and an effective power of 3288.09 Watt while the value SFCE by 0.33 Liter / Jam.Watt. This proves that, biogas purification using paste pumice stone is able to improve quality of biogas.
