A Correlation Between Students' Mastery of Simple Past Tense and Their Ability in Writing Recount Text

The result of the research showed that the mean for the mastery of simple past tense was 30.76 mean for writing ability of recount text was 59.06. From those data, 0.9201 was gotten for the coefficient rxy. Because the coefficient rxy was not equal with 0, the null hypothesis (HO) was rejected and the alternative hypothesis (Ha) was confirmed. Therefore, there was a significance correlation between student's mastery of simple past tense and their ability in writing recount text at the evaluate grade students of SMAN 16 MAKASSAR in the academic year 2015/2016. Due to the result of this research, the student should study more about simple past tense specifically and grammar generally. They should also study text types completely include their generic structures and lexicon grammatical features. Then teacher as the facilitator should be able to facilitate the need of the students in any materials

Penggunaan Jerk Untuk Deteksi Dini Kerusakan Bantalan Gelinding Dan Pemantauan Kondisi Pelumasan

This paper describes the use of jerk signal, a signal obtained from differentiation of the acceleration signal with respect to time, for detecting the early damage of a bearing and bad lubrication conditions. The use of jerk signal is expected to result more sensitive detection than that obtain using acceleration signal. To prove this hypothesis, this paper shows the results of vibration measurement for needle bearings and taper roller bearings with variation of load level, types of bearing damage, and lubrication condition. Comparisons of acceleration and jerk signals are performed in both time domain, by comparing their RMS values, as well as in frequency domain, by comparing their spectrums. The results of the experiment show that the use of jerk signal can give a more sensitive result in detecting bearing damage than that produced using acceleration signal. Moreover, the use of jerk signal can lead to better results in detecting bad lubrication of rolling bearing than that obtain using Crest Factor (CF) value

Effect Of Nutrient Deficient Media & Environmental Stressors On Microalgal Growth

Research on microalgae has been greatly developed as microalgae are one of the new fast solution‟s to many of world‟s problems such biofuel, environmental remediation, aquaculture and hunger. Microalgae are great factory because of their components that can be extracted and converted into many kinds of product. Every single cell of microalgae is a tiny factory which produces certain useful products. A few of the important extracted product are lipid, carbohydrate and protein, and different species of algae produce different composition of this amount. In order to produce valuable products, it is very important to view algae culture under different environmental stressors to maximize algae production. The studies in this project are based on four different species, which are Isochrysis galbana spp., Tetraselmis batan spp., Nannochloropsis spp. and Pavlouva lutheri spp. The optimum number of cells and kinetic growth of 250C, pH 7, and 24 hours normal light intensity are determined. The extractions of lipid from both fresh and dried algae are done. Different environmental stressors are given to Pavlouva lutheri spp (salinity and photoperiod) and the optical density and amount of lipid content are verified

Total phenolic content, antioxidant and cytotoxic activity of cocoa (Theobroma cacao L.) polyphenols extracts on cancer cell lines

Introduction: Cancer chemopreventive agents from natural sources have been actively investigated over the years to seek prevention against cancer. In this study, cocoa polyphenols extract (CPE) was examined to explore its antioxidant and cytotoxicity activities. Methods: CPE was analysed for total phenolic content (TPC) and antioxidant activity (DPPH radical scavenging activity and FRAP ferric-reducing antioxidant power assays). In vitro cytotoxicity effect of CPE against HepG2, HT-29, HeLa, MCF-7, MDA-MB-231 and WRL-68 cell lines after 48 h exposure was measured by MTT assay. Results: The study showed that CPE had higher total phenolic content (13560.0±420.1 mg GAE/100g dry weight of sample) than vitamin E (p<0.05). CPE exhibited strong antioxidant activity comparable with ascorbic acid in both DPPH (IC50 = 14.73±1.47 μg/ml) and FRAP (2130.33±2.33 μM of FE/1 mg of dry weight of sample). The cytotoxicity study showed that CPE exhibited the highest cytotoxicity effect against MCF-7 with lowest IC50 value (3.00±0.29 mg/ml) compared to other cancer cell lines after 48 h treatment (p<0.05). Conclusion: Our results indicate that CPE demonstrated high total phenolic content, free radical scavenging activity, ferric reducing ability and cytotoxicity activity towards HepG2, HT-29, HeLa, A549, MDA-MB- 231 and MCF-7 cancer cell lines. Further isolation of bioactive constituents from CPE should be done to characterise its potential chemopreventive activity as well as to elucidate the mechanism of cancer cell death induced by CPE

Manajemen Montir Dalam Perbaikan Mesin Berdasarkan Simulasi Discrete-Event (Studi Kasus: PT. ISTW Semarang)

Untuk meningkatkan performansi sistem produksi, diperlukan adanya sistem perawatan mesin-mesin produksi yang baik. Perawatan dikelompokkan menjadi preventive maintenance dan corrctive maintenance. Perawatan preventive dilakukan secara berkala untuk memperpanjang umur mesin dan juga untuk mencegah terjadinya kerusakan mesin produksi ketika digunakan. Sedangkan perawatan korektif dilakukan hanya pada saat mesin produksi mengalami kerusakan. Dalam Kenyataan, mesin produksi mengalami kerusakan pada saat proses produksi berlangsung meski telah dilakukan perawatan preventive pada mesin tersebut. Untuk kerusakan seperti itu diperlukan corrective maintenance agar proses produksi tidak terhenti terlalu lama. Peran montir sangat penting untuk menangani kerusakan mesin dalam corretive maintenance. Penelitian ini menyajikan suatu model simulasi yang menggambarkan beberapa cara mengelola montir, yatu dalam penugasan montir. Cara yang pertama adalah penugasan montir tanpa memperhatikan prioritas kerusakan dan banyaknya montir yang dialokasikan sama untuk setiap kerusakan. Cara kedua adalah penugasan montir dengan memperhatikan prioritas kerusakan dan banyaknya montir sama untuk setiap kerusakan. Cara ketiga adalah penugasan montir dengan memperhatikan prioritas kerusakan dan alokasi montir yang disesuaikan dengan tingkat kerusakan yang akan diperbaiki. Dari analisa output, cara pertama penugasan montir memberikan hasil banyaknya pipa baja yang dihasilkan adalah 343.308 batang pipa. Cara penugasan kedua memberikan hasil sebanyak 345.614 batang pipa. Cara penugasan ketiga hasil memberikan hasil sebanyak 353.263 batang pipa baja

Model Simulasi Pengalokasian Jumlah Montir Perawatan Mesin Di PT. Istw Semarang

Untuk meningkatkan performansi sistem produksi maka diperlukan adanya sistem perawatan yang baik untuk mesin-mesin produksi. Sehingga kemungkinan terjadinya kerusakan mesin pada saat proses produksi berlangsung dapat ditekan seminimal mungkin. Perawatan dapat dibagi menjadi 2 macam, yaitu perawatan jenis preventive dan perawatan korektif. Perawatan preventive dilakukan secara berkala untuk memperpanjang umur mesin dan juga untuk mencegah terjadinya breakdown pada mesin produksi pada saat sedang digunakan. Sedangkan perawatan korektif dilakukan hanya pada saat mesin produksi mengalami kerusakan. Dalam Kenyataannya, terkadang mesin produksi tetap akan mengalami breakdown pada saat proses produksi berlangsung meskipun telah dilakukan perawatan preventive pada mesin tersebut. Untuk kerusakan seperti itu diperlukan penanganan secepatnya agar proses produksi tidak terhenti terlalu. Peran montir sangat penting untuk menangani breakdown mesin. Dengan adanya sistem perbaikan yang baik maka mesin produksi dapat segera diperbaiki dan kerugian karena kerusakan mesin dapat dikurangi. Penelitian ini menyajikan suatu model simulasi yang menggambarkan beberapa sistem penugasan montir. Cara yang pertama adalah penugasan montir tanpa memperhatikan prioritas kerusakan dan jumlah yang dialokasikan sama untuk setiap kerusakan. cara kedua adalah,penugasan montir dengan memperhatikan prioritas kerusakan dan jumlah alokasi montir sama untuk setiap kerusakan. Cara ketiga adalah penugasan montir dengan memperhatikan prioritas kerusakan dan alokasi montir yang disesuaikan dengan tingkat kerusakan yang akan diperbaiki.Dari analisa output didapatkan hasil bahwa dengan menggunakan cara penugasan montir yang pertama didapatkan hasil jumlah pipa baja yang dihasilkan adalah 343.308 batang pipa. Dengan cara penugasan yang kedua didapatkan hasil sebanyak 345.614 batang pipa. Dan dengan cara penugasan yang ketiga hasil yang didapatkan adalah 353.263 batang pipa baja
