Abstract

Unconfined compression strength and CBR values of sandy clay are influenced by several factor such as sand and clay content, soil properties, density, moisture content, and gradation. This research tries to figure out the effect of sandy clay gradation on its unconfined compression strength and CBR values. Sandy clay mixtures were made from different percentage of sand and clay fractions. Sand fraction gradation varied from well to poor (gap). Clay was also stabilized with quick lime. The results of this research indicated that the addition of sand and lime into clay increased unconfined compression strength and CBR values, especially after 28 days curing time. The largest value of unconfined compression strength test occurred at mixture with 70% clay, due to the cohesiveness obtained from clay and lime stabilisation. The largest CBR values were found in the mixture with less contained clay.Keywords: unconfined compression strength,CBR, gradation, density, sand, clay

Abstract

Sand of Pulau Island Bungin is a natural sand that comes from Batang Kuantan River, Koto Taluk Kuantan Village, District Kuantan Tengah, Kuantan Singingi Regency, Riau Province. The availability of natural sand makes progress of Kuantan Singingi regency because it is easily obtained and more economical do not need to bring sand material from other area and do not have to go through stone breaking process by stone crusher. Based on the a general Specification Bina Marga 2010 Revision 3, the use of natural sand for asphalt concrete mixture (AC) should not exceed 15% of the total aggregate mixture weight. Therefore, we need to know the efficiency of natural sand usage in asphalt concrete mix (AC) for optimal utilization. This study aims to find out how optimum asphalt (KAO) and to know Marshall characteristics whether to meet the General Specification of Bina Marga 2010 Revision 3. The fine aggregate variation of natural sand used in this research is 0%, 5%, 10%, 15%, 20 % Of the total weight of the aggregate mixture. The addition of natural sand in the asphalt concrete wearing course (AC-WC) causes the value of optimum asphalt (KAO) to decrease. In the mixed asphalt concrete wearing course (AC-WC), the addition of 10% saturated sand obtained an optimum asphalt (KAO) value of 6,10% and the largest stability value of 1.343 kg. If without considering the limits of natural sand usage as set out in Specification of Bina Marga 2010 Revision 3 then the natural addition of sand may still be used in asphalt concrete wearing course (AC-WC) until 20%.Keywords: Natural sand, mixed asphalt concrete wearing course (AC-WC), characteristics of Marshall and a general Specification Bina Marga 2010 Revision 3.

Abstract

Asphalt concrete wearing course (AC-WC) is the top layer in flexible pavement. Asphalt concrete is a mixture of asphalt, coarse aggregate, fine aggregate and filler. Many types of filler have been used to improve asphalt concrete performance. In this research, a combined of brick ash and rice husk ash was used as filler. As wasted products, this mixed filler can be used as an alternative replacement of Portland cement due to their similar chemical compounds. The objective of this research is to analyze Marshall characteristics (stability, flow, volumetric properties and Marshall Quotient) of an ACWC mixture containing a combination of Portland cement and a mixed of 40% brick ash and 60% rice husk ash as filler. Ratios of cement and the mixed ash used were 100:0, 50:50, and 0:100. After obtaining the optimum asphalt content for each different filler variation, Marshall test were performed to obtain flow, stability and density values. The result of tests showed that the composition of filler 50:50 gives Marshall characteristics with stability value of 1250,5 kg and air void of 4,846%. The composition of filler 0:100 gives Marshall characteristics with the highest stability value of 1692,9 kg and the smallest air void of 4,533%, which satisfied the specifications of Bina Marga 2010 Revision 3. Keywords: rice husk ash, brick ash, AC-WC, filler

Abstract

Pendahuluan : Tuberkulosis (TB) adalah suatu penyakit infeksi menular yang disebabkan bakteri Mycobacterium tuberculosis, yang dapat menyerang berbagai organ, terutama paru-paru. Penyakit ini bila tidak diobati atau pengobatannya tidak tuntas dapat menimbulkan komplikasi berbahaya hingga kematian.Penemuan tersangka kasus tuberkulosis adalah salah satu indikator evaluasi upaya menanggulangi tuberkulosis paru. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pengetahuan keluarga tentang TB terhadap penemuan dini TB di wilayah kecamatan Jaten dan Puskesmas Jaten II dan sekitarnya. Metode : Penelitian ini menggunakan metode deskriptif observatif. Responden penelitian adalah anggota keluarga penderita TB atau penderita TB kecamatan Jaten Puskesmas Jaten II. Cara pengambilan sampel dengan menggunakan kuesioner pengetahuan mengenai TB dengan konsekutif sampling. Hasil : Hasil penelitian menunjukkan memiliki pengetahuan baik (58%) dan Kurang (42%) mengenai TB dan hasil deteksi penemuan TB didapatkan mayoritas BTA >+1 (Terlambat). Kesimpulan : Dari data dapat disimpulkan bahwa tingkat pengetahuan masyarakat tentang TB tidak berhubungan positif dengan keberhasilan penemuan dini kasus TB. Disarankan perlunya melakukan pendekatan edukatif dan psikologi pada masyarakat untuk meningkatkan kepedulian masyarakat dalam membantu penemuan kasus TB secara aktif dan melakukan upaya menghilangkan stigma TB pada masyarakat. Analisis yang digunakan yaitu analisis univariat untuk mengetahui distribusi tiap variabel yang diteliti dan analisis bivariat menggunakan uji chi-square dengan ? = 0,05. Didapatkan hasil p value = 0,214. Hasil menunjukkan tidak ditemukannya Pengaruh yang signifikan dari Pengetahuan Keluarga Tentang Tuberkulosis terhadap Penemuan Dini Tuberkulosis di Kecamatan Jaten.Kata Kunci : Early TB Detection,TB knowlodge, family members

Abstract

Maximum Power Point Tracking is a method to track power point of an energy source in order to generate maximum power. One of the MPPT method for photovoltaic system is fractional open voltage MPPT. In this paper the fractional open voltage MPPT is modified by using artificial neural network trained using genetic algorithm. Artificial neural networks are successfully trained by using genetic algorithm. The best mean squared error (MSE) value obtained is 0.000453. The network tested using test data, yielding average error = 0.00949509 and MSE = 0.00012814. The neural network-based MPPT can improve the fractional open voltage MPPT by 4.79%.Index Terms---Genetic Algorithm, MPPT, Neural Network, Photovoltaic

Abstract

Inflammatory mediators, such as prostaglandins and histamines can cause pain. Non steroid anti-inflammatory drugs (NSAIDs) have been indicated to reduce pain on inflammatory conditions. Pharmacologically, NSAIDs inhibit prostaglandins which are synthesized from arachidonic acid by blocking cyxlooxygenase-1 and 2 enzymes. Prostaglandins are known to be overexpressed on inflammatory, premalignant and malignant conditions. The prostaglandins promote tumour development bu enhancing tumour cells proliferation, tumour angiogenesis, and tumour cell metastatic opportunity, and by inducing antiapoptotic gene expression. Epidemiological and biomedically, there is significant evidence that NSAIDs could inhibit tumour development. NSAIDs inhibit expression transcription factors, angiogenic factors of tumour angiogenesis, tumour metastasis and depresse expression of antiapoptopic genes. This evidence suggest that potentially NSAIDs could prevent tumour development, besides being analgesic-antiinflammatory drugs.
