Abstract

Introduction: Free radical formation in the cochlea plays a key role in the development of noiseinduced hearing loss(NIHL). The aims of this study is to assess combination the effect of beta carotene, vitamin C, and vitamin E on levels of malondialdehyde (MDA) and Transient Otoacuistik Emission (TEOAE) post noise exposure.Method: Three groups of rabbits used in this study, each consisting of 5 rabbits. The first groupcontrol received no treatment. The second group is exposed to 100 dB noise at a frequency of 1000 Hz 4 hours daily for seven day, and the third group are exposed to noise exposure and with beta carotene (2.1 mg/kg), vitamin C (71.4 mg/kg and vitamin E 26 mg/ kg) orally for 7 days. MDA levels and signal to noise ratio (SN) value as parameter of TEOAE in all three groups were measured before and after treatment.Result: In the second and third group MDA levels increased significantly at the end of treatmentcompared to control group (p<0.05). The value of SN also decreased significantly compared the control group (p<0.05). Increased levels of MDA after treatment in the third group is smaller than the second group (p<0.05). The difference in change SN value at the end of treatment in the third group are significantly different than the second group (p<0.05).Conclussion: Exposure to noise can increase the levels of MDA and decrease the value of SN in rabbits and providing a combination of beta carotene, vitamin C and vitamin E can reduceelevated levels of MDA and decrease in the value of SN post noise exposure.

Abstract

The objective of this quantitative study is to investigate whether there any influence of using a picture in teaching degree of comparison or not and to know the students’ responses at the second year students of SMP Negeri 9 Mataram in academic year 2014/2015. The population of this study was taken from all the second year students. The writer chose two classes to compare by using the technique of taken sample “cluster random sampling.” The first class as the experimental class (A class) was taught by the degree of comparison through pictures. The second class as a control class ( B class) was taught without pictures. While 34 students of the experimental group and 34 students of the control group. This study used an experimental study with a quantitative method — the data collected procedure by test and questionnaire. The writer gave the pre_test, the treatment, the post_test, and the questionnaire. After collecting and calculating the data, the writer found out that the experimental class gains a high score than the control class. Based on the result, the means scores of A class was 25 while the B class was 16. Moreover it was found that the value of t_test was higher than t_table, where t_test 2, 5 ≤ t_table = 2, 0 (0, 5% or 95%). The finding showed that there any influence of using the picture in teaching comparison degrees. The picture increases students’ responses to learning degree of comparison the class and also given good influence concerning students’ skill in mastering the subject of comparison degrees. It showed by students’ responses of the data from the questionnaire that more than half of students answer yes with percentage was 73%.

Abstract

ABSTRAKPenelitian ini bertujuan untuk Membuat dan mengimplementasikan aplikasi pengolahcitrauntukmenentukanjenistanahpadalahanpertaniandengan menggunakan metode Gray Level Co-occurence Matrices diimplementasikan menggunakan bahasa pemrograman Visual Basic 6.Pemilihan lahan pertanian di Indonesia, secara umum, dilakukan sendiri oleh petani tanpa memperhitungkan kesesuaian lahan tersebut dengan tanaman yang akan diaplikasikan. Hal ini dapat berakibat pada berkurangnya hasil panen. Klasifikasi jenis tanah juga dapat dilakukan dengan menganalisis hasil pengukuran dari Cone Penetration Test (CPT). Namun, CPT menggunakan peralatan khusus yang akan sulit diadakan oleh para petani. Selain menggunakan peralatan khusus, terdapat tata cara yang harus ditaati oleh pihak yang akan melakukan CPT. Berdasarkan permasalahan yang telah diuraikan, akan dirancang sebuah aplikasi yang dapat menentukan jenis tanah pada lahan pertanian. Citra tanah pada lahan pertanian akan diolah menggunakan Gray Level Co-occurrence Matrix (GLCM). Dengan GLCM, ekstraksi ciri dapat dilakukan pada citra tanah, sehingga dapat ditentukan jenis tanah dari citra tersebut. Hasil yang diperoleh adalah berupa perancangan aplikasi yang dapat melakukan ekstraksi ciri pada citra tanah menggunakan metode GLCM.Kata Kunci: Klasifikasi jenis tanah, ekstraksi ciri, GLCM.

KRITIK EKONOMI ISLAM MODERN

Abstract

Kebangkitan ekonomi negara-negara Islam telah menunjukkan hasil yang menggembirakan  terutama  pada variabel-variabel makro dan mikro ekonomi. Hal tersebut didasarkan pada asumsi bahwa reformasi sosial ekonomi telah diimplementasikan dengan berhasil, model mudharabah dan musyararakah telah dijalankan, dan sejumlah lembaga tambahan yang dibutuhkan untuk memfasilitasi berjalannya fungsi dari model-model ini juga telah ada. Namun kendala yang dihadapi beberapa negara Islam sesungguhnya cukup besar mengingat dalam prakteknya sejumlah nilai-nilai Islam banyak yang terlupakan dan sangat susah untuk diimpelementasikan secara seragam  yang pada gilirannya menyebabkan banyak lembaga-lembaga keuangan Islam  terperangkap dalam jebakan lembaga keuangan konvensional.  Suatu perekonomian yang bebas bunga merupakan sebuah visi dari kaum muslimin dan ini merupakan tugas dari pemerintah untuk menentukan cara terbaik untuk memenuhi permintaan ini. Bunga dapat dengan berhasil dihilangkan hanya apabila dilakukan secara simultan terhadap seluruh aktifitas ekonomi. Strategi ini  dapat dilakukan dengan memasukkan pelarangan bunga pada sektor ekonomi dengan memperkuat lembaga-lembaga keuangan secara demokratis, menghilangkan korupsi dari pemerintah dan sistem perbankan, meminimalisir ketidakseimbangan makroekonomi dan memulai sejumlah reformasi sosial ekonomi, hukum dan kelembagaan yang diperlukan

Abstract

This study was conducted to see the trend of diseases caused by unhealthy lifestyles on disadvantaged communities and coastal villages around Gresik and Tuban using hybrid algorithms through the construction of the structure of Bayesian Network. The problem to be solved in this study is no system that can detect a relationship between unhealthy behavior that caused the disease. Model of this structure has never been applied directly in the field to detect a causal events for example, if a behavior is unhealthy will arise disease. Application of this model needs to be done with a field study to determine and prove the actual benefits of the concept of a hybrid construction of Bayesian network structure. The purpose of this research is to produce a software model capable of early detection of disease risk propensity underdeveloped rural and coastal communities who have unhealthy lifestyles in the form of construction of the structure and generates a probability value with a tendency disease. The comparison between the structure of the origin of the structure of the trial results indicate the level of suitability for complete test data difference of 10% to the original structure, and suitability for the test data is incomplete for more than 20% depending on the amount of his missing value. The validity of that smoke will have the tendency has tuberculosis disease, bronchitis or Lung Cancer through the test system is 80% to 90%.

Abstract

Dalam penelitian ini dikembangkan metode pengaturan kecepatan motor induksi 3 phasa menggunakan kendali LQR dan DTC. Dengan menggunakan metode LQR dan DTC memungkinkan untuk mengontrol torka dan fluks stator secara langsung. Estimasi putaran rotor, torka dan fluks dilakukan oleh DTC yang diberi input tegangan dan arus stator.estimsi kecepatan motor akan dibandingkan dengan kecepatan referensi untuk menghasilkan error. Error dan delta error kecepatan putar sebagai masukan pada kendali LQR.Hasil yang diperoleh melalui simulasi menunjukkan respon kecepatan putar yang cepat dalam kondisi start, perubahan beban dan perubahan set point. Pada kondisi perubahan beban, respon kecepatan hampir tidak mengalami perubahan kecepatan atau bisa dikatakan respon kecepatan kokoh bila ada gangguan, maksimum overshoot sebesar 4,6735 % untuk torsi beban 30 N.m dengan peak time 0,007 detik dan settingtime sebsar 0,111 detik. Untuk kecepatan referensi 1450 rpm errornya sebesar 0,03 % kecepatan referensi 725 rpm errornya sebesar 0.03 % kecepatan 725 rpm errornya 0,08 dan untuk kecepatan referensi 362,5 rpm errornya 0,027 % terhadap kecepatan aktual motor.
