Comparison between the Use of LMA™ and SLIPA™ in Patients Undergoing Minor Surgeries.

Supraglottic airway devices have been used as safe alternatives to endotracheal intubation in appropriate types of surgery. This was a prospective, randomised, single blind study comparing the use of LMA™ and SLIPA™ in terms of ease of insertion, haemodynamic changes and occurrence of adverse effects (e.g. blood stains on the device upon removal and sore throat). A total of 62 ASA I or II patients, aged between 18 to 70 years were recruited for this study. Patients were randomised into two groups; LMA™ and SLIPA™ group. Following induction of anaesthesia, an appropriate sized LMA™ or SLIPA™ was inserted after ensuring adequate depth of anaesthesia. Anaesthesia was maintained with oxygen, nitrous oxide and sevoflurane. The ease of insertion was graded and haemodynamic changes were recorded at 2 minute intervals up to 10 minutes after insertion of the airway devices. The presence of blood stains upon airway device removal at the end of surgery and incidence of sore throat was also recorded. No difficult insertion was experienced in either of these devices. Insertion was either easy [LMA™ 87.1% versus SLIPA™ 80.6% (p = 0.49)] or moderate [LMA™ 12.9% versus SLIPA™ 19.4% (p = 0.16)]. Throughout the study period, the haemodynamic changes that occurred in both groups were not statistically different. Traces of blood were noted on the surface of the device in 9.7% of patients in the SLIPA™ group versus 6.5% of patients in the LMA™ group. The incidence of sore throat was recorded in 12.9% versus 19.4% of patients in the SLIPA™ and the LMA™ groups respectively. These findings were not statistically significant. In conclusion, this study showed no significant differences between the use of LMA™ and SLIPA™ in terms of ease of insertion, haemodynamic changes and adverse effects in patients undergoing minor surgical procedures

AL-QUR’AN DAN PLURALITAS: Membangun Kehidupan Masyarakat yang Majemuk

Abstrak: Tulisan ini mengkaji konsep pluralisme agama sebagaimana terdapat dalam ayat-ayat al-Qur’an. Semua agama-agama di dunia pada waktu tertentu telah takluk kepada tekanan sekuler dan menundukkan pesan moral-spiritual utama di bawah ambisi politis dan interest komunitas khusus mereka. Al-Qur’an menginfor- masikan bahwa pluralisme agama merupakan sesuatu yang alami (sunnah Allâh), dan manusia diciptakan dalam pluralitas, bahkan jika Tuhan menghendaki, tentu Dia menjadikan manusia umat yang satu, sekalipun secara faktual tidak demikian. Penulis menemukan bahwa pluralisme agama dalam al-Qur’an, bukan saja untuk memberikan kahidupan yang layak intern umat Islam, tetapi lebih dari itu memberikan semangat hidup berdampingan dengan umat lainnya, baik dalam kehidupan keagamaan, kebangsaan, dan kehidupan antar bangsa.Abstract: Al-Qur’an and Plurality: Building Heterogeneous Social Lives. This article studies the pluralism related concepts according to the verses of the Qur’an. All the world religions at a certain time had overruled by secular pressure and had controlled the fundamentals of moral-spiritual message for the sake of the political ambition and interest of their certain communities. The Qur’an informs that religious pluralism is something natural, and humankind is created in plurality, and even if God so Will, He should have created man in a single community, although this is contrary to the fact. The author finds that pluralism according to the Qur’an, does not only cater the proper Muslim lives internally, but, above all, also provide for the spirit of living together with other community both in matters of religious, national and international lives.Kata Kunci: pluralitas, al-Qur’an, masyarakat majemu

An experimental study of welded bar sleeve wall panel connection under tensile, shear, and flexural loads

This paper presents an experimental study of a new grouted splice connection for wall panels, called Welded Bar Sleeve (WBS). The connections were made from steel pipes and tested with incremental tensile, shear and flexural loads until failure. The aim is to determine the behaviour of the connection under the three load cases. For this, the connections are evaluated in terms of the load–displacement responses, ultimate capacities, ductility responses and some feasibility assessment criteria. WBS was found to provide sufficient strength at the bar embedded length of 8, 8 and 11 times the bar diameter under tensile, shear and flexural loads, respectively. It is effective under tension, but could only service up to 1/3 of its ultimate shear capacity. Flexural load is the most critical load case for the connection. For this, further enhancements are required when subjected to shear and flexural loads

REGENERASI ALAMI SEMAIAN MANGROVE DI KAWASAN TELUK BENOA, BALI

Mangrove ecosystems have an important role in coastal areas either directly or indirectly. The preservation of the mangrove ecosystem can be described from the seedlings' abundance. Mangrove natural regeneration status was carried out in the Benoa Bay, Bali. The study was aimed to analyze the current natural mangrove regeneration based on the seedling abundance and its correlation with ecological characters. The study area was divided into three zones consist of 30 sampling quadratic plots in total. Seedling and mature stands community structure and environmental parameters data were collected from each plot. Based on the result, the mangrove regeneration state was categorized as fairly good condition. It was implied by seedling abundance compared with tree and sapling density. The highest seedling density was found in zone 2 which was dominated by Rhizophora mucronata with an average of 4800 ± 5610 stands/ha. It was significantly different from the other two zones. Variations of the community structure in the three zones had no significant influence on seedlings distribution. Only two environmental factors i.e. pH and redox potential, had a positive correlation and significant correlation with the abundance of mangrove seedlings. The result indicated that the mangrove regeneration state in this area was maintained even though it had faced variable threats.Ekosistem mangrove memiliki peran penting dalam kawasan pesisir baik secara langsung maupun tidak langsung. Kelestarian ekosistem mangrove dapat digambarkan dari kelimpahan semaian. Penelitian tentang status regenerasi alami mangrove telah dilakukan di kawasan Teluk Benoa, Bali. Tujuan penelitian ini adalah untuk menganalisis tingkat regenerasi mangrove berdasarkan kelimpahan semai, serta hubungannya dengan karakter ekologi mangrove dalam kawasan. Area penelitian dibagi menjadi tiga zona dengan total 30 titik pengambilan sampel dengan distribusi yang proporsional. Pada setiap titik dilakukan pengambilan data struktur komunitas semai, tegakan dewasa (pohon, pancang) dan parameter lingkungan. Hasil penelitian menunjukkan status regenerasi mangrove di kawasan ini termasuk dalam kategori cukup baik, berdasarkan perbandingan dari kelimpahan semaian dengan tegakan kategori pancang dan pohon. Kerapatan semai tertinggi ditemukan pada zona 2 yang didominasi oleh Rhizophora mucronata dengan rata-rata sebesar 4800 ± 5610 tegakan/ha yang berbeda signifikan dengan dua zona lainnya. Variasi kondisi struktur komunitas mangrove pada tiga zona tidak memberikan pengaruh yang signifikan terhadap kelimpahan semai. Sementara itu, dua faktor lingkungan yaitu pH dan potensial redoks memiliki korelasi yang positif dan signifikan memengaruhi jumlah sebaran semai mangrove di dalam kawasan. Hasil penelitian mengindikasikan bahwa tingkat regenerasi mangrove masih mampu bertahan dalam tekanan habitat yang cukup tinggi

APLIKASI SISTEM INFORMASI GEOGRAFI BERBASIS DATA RASTER UNTUK PENGKELASAN KEMAMPUAN LAHAN DI PROVINSI BALI DENGAN METODE NILAI PIKSEL PEMBEDA (Application of Geographic Information System (GIS) Based Raster Data to Classify Land Capability in Bali)

ASBTRAKPenggunaan teknologi seperti SIG sangat baik untuk mengelompokkan data keruangan lahan berdasarkan faktor potensi dan penghambat penggunaannya. Dengan mengimprovisasi metode tumpang susun diharapkan mampu mempercepat proses studi tentang pengkelasan kemampuan lahan. Tujuan penelitian ini adalah pengaplikasian SIG berbasis data raster untuk memetakan kelas kemampuan lahan di Provinsi Bali dengan menggunakan metode ”nilai piksel pembeda”. Hasil penelitian menunjukkan bahwa penggunaan SIG dapat memperlihatkan sebaran kelas kemampuan lahan yang heterogen dan kompleks sehingga memperjelas informasi lahan pada satuan unit lahan yang sempit. Selain itu penggunaan metode ini juga membantu mempercepat proses tumpang susun dan query data. Kelas kemampuan lahan di Provinsi Bali dapat dikelompokkan menjadi 8 kelas, dari kelas I sampai kelas VIII. Sebaran kelas kemampuan lahannya didominasi oleh lahan dengan kelas VI, VII dan VIII yaitu seluas 50,7% dari luas Provinsi Bali. Kabupaten Buleleng, Jembrana, dan Karangasem berturut-turut merupakan daerah-daerah terluas yang memiliki kemampuan lahan kelas VIII. Daerah-daerah tersebut harus lebih instensif dalam menjaga lahan-lahan berkelas VIII agar tidak beralih fungsi dari lahan hutan menjadi lahan non hutan.ABSTRACTThe use of technologies such as GIS  are very good for spatial data classifying based on potential and inhibiting use factors. With improvise an overlay method expected to accelerate study process about land capability classifying. The purpose of this research is the application of GIS based raster data to mapping land capability class in Bali Province by using "differentiator pixel value". The results showed that the use of GIS can show the heterogeneous and complex distribution of land capability classes and can clarify the land information on a narrow land unit. Furthermore, the uses of this method also help to accelerate the overlay and query data process. The distribution of land capability class is dominated by land with class VI, VII and VIII, which is covering 50.7% of the Bali Province. Districts that have a biggest land capability class VII is Buleleng, Jembrana, and Karangasem, respectively. Therefore, these districts should be more intensive to keeping the lands class VIII for not switching function from forest into non-forest land

Effect of Nano-Silica on The Thermo-Physical Properties of the Thermal Eutectic (Na0.6K0.4)NO3 System

Here, we investigate the effect of adding nano-silica particles on the thermo-physical properties of the (Na0.6K0.4)NO3 based thermal energy storage systems. Five different systems tagged as M00, M01, M02, M03 and M04, with different nano-silica percentage of 0, 1, 2, 3, and 4 wt%, respectively, were prepared. Various experimental techniques were employed to study the thermo-physical properties of the systems during (solid-solid) phase P1, (solid-liquid) phase P2 and (liquid-solid) phase P3, and to clarify the effect of nano-silica on the thermal energy storage efficiency during both charging and discharging processes. According to the Differential Scanning Calorimeter (DSC) thermal analysis, it was found that the system M02 whose nano-silica addition rate of 2 wt%, has the most favorable thermal characteristics (i.e., highest specific heat and lowest enthalpy change). Moreover, the addition of 2 wt% represents the optimum distribution of nano-silica inside the principal base system M00. This leads to an improvement in the porosity of the system due to the degree of homogeneity caused by the thermophoresis effect distribution, the high surface area of the nano-silica with the activity of the M00 matrix alongside the degree of the alkalinity of nano-silica. Besides, the electric conductivity measurements showed that the 2wt% percentage is the optimum one for thermal energy storage systems
