Analisis Tingkat Pengangguran Di Jawa Tengah Tahun 1997-2010

The unemployment rate in Central Java have fluctuated from year to year from 1997 to 2010. The unemployment rate is highest in 2007, reaching 7.70%. While the unemployment rate is the lowest in 2001, amounting to 3.70%. This study aims to analyze the relationship between population, inflation, average - minimum wage districts / cities, and the GDP growth rate with the unemployment rate. The test results showed a correlation coefficient of independent variables that have a positive and significant relationship with the dependent variable is the number of inhabitants and the minimum wage regencies / municipalities in Central Java. Variable numbers of the population has correlation coefficient of 0.755 while the minimum wage variable districts / cities have numbers correlation coefficient of 0.878 so it can be concluded that the higher the population, the greater the minimum wage and district / city positively and significantly associated with the level of unemployment in Central Java. Variable rate of inflation has correlation coefficient of -0.173 points while the variable rate of GDP growth has a correlation coefficient of -0.179 so it can be concluded that the variable inflation rate and GDP growth rate variable has a negative and significant relationship with the level of unemployment in Central Java. Correlation coefficient of inflation rate and GDP growth rate indicated by the negative sign means the rate of inflation and GDP growth rate has no significant relationship with unemployment

Pengembangan Ular Tangga Modifikasi (Ultamod) Untuk Mengoptimalkan Perkembangan Anak

Penelitian ini bertujuan untuk mengembangkan permainan dan media Ular Tangga Modifikasi (Ultamod) guna mengoptimalkan perkembangan anak usia dini. Penelitian ini mengacu pada model pengembangan Borg & Gall namun hanya sampai pada tahapan nomor 3 yaitu pengembangan prototipe dengan penilaian validator. Teknik pengumpulan data menggunakan skala dengan instrumen lembar skala dan analisis data menggunakan analisis data kuantitatif. Data kuantitatif kemudian dikonversikan ke data kualitatif dengan rumus persentase untuk mengetahui kualitas produk. Target penelitian ini adalah terciptanya Ultamod dan panduan penggunaannya, yang dapat digunakan sebagai alternatif media pembelajaran di PAUD yang dapat mengembangkan keenam aspek perkembangan anak usia dini, yaitu nilai agama moral, fisik motorik, bahasa, kognitif, sosial emosional dan seni. Berdasarkan hasil uji validator, maka media ular tangga modifikasi dan buku petunjuk penggunaan yang telah dibuat peneliti dinyatakan layak diuji coba lapangan dengan revisi. Hal ini dapat dilihat dari pengujian instrumen oleh validator yang secara keseluruhan uji materi diperoleh hasil 78,57 % (baik) dan uji media diperoleh hasil 80 % (baik)

Computation of Neutron Star Structure Using Modern Equation of State

Using the modern equations of state derived from microscopic calculations, we have calculated the neutron star structure. For the neutron star, we have obtained a minimum mass about $0.1 {\rm M_{\odot}}$ which is nearly independent of the equation of state, and a maximum mass between $1.47 {\rm M_{\odot}}$ and $1.98 {\rm M_{\odot}}$ which is strongly dependent on the equation of state. It is shown that among the equations of state of neutron star matter which we have used, the stiffest one leads to higher maximum mass and radius and lower central density. It is seen that the given maximum mass for the Reid-93 equation of state shows a good consistency with the accurate observations of radio pulsars. We have indicated that the thickness of neutron star crust is very small compared to the predicted neutron star radius.Comment: 16 pages, 6 figure

Peramalan Harga Saham Jakarta Islamic Index Menggunakan Metode Vector Autoregressive

Saham merupakan instrumen investasi yang banyak dipilih para investor, karena saham mampu memberikan tingkat keuntungan yang menarik. Sejak 12 Mei 2011, Bursa Efek Indonesia (BEI) mempunyai dua indeks harga saham Syariah, yaitu Indeks Saham Syariah Indonesia (ISSI) dan Jakarta Islamic Index (JII). Saham-saham dalam indeks ini mempunyai keistimewaan yaitu memiliki tingkat hutang yang rendah, sehingga risiko dalam berinvestasi semakin terkendali [1]. Terdapat 8 sektor di dalam indeks JII salah satunya adalah sektor properti. Perkembangan industri properti dan real estate menunjukkan pertumbuhan yang sangat pesat. Hal ini ditandai dengan maraknya pembangunan Perumahan, apertemen, perkantoran dan perhotelan di kota-kota besar. fluktuasi harga saham sektor properti merupakan salah satu masalah bagi investor dalam menjual atau membeli saham sehingga diperlukan analisis untuk meramalkan harga saham guna meminimalkan risiko yang diperoleh. Metode VAR adalah metode yang digunakan untuk meramalkan data dua variabel atau lebih yang memiliki hubungan timbal Balik. Berdasarkan analisis peramalan harga saham sub sektor properti dan real estate dengan metode VAR maka dapat diketahui model akhir yang terbentuk adalah VARX (1,1) dengan RMSE 3 periode ke depan variabel ASRI sebesar 6,2, BSDE sebesar 22,4, LPKR sebesar 22,7, PWON sebesar 12,8, dan SMRA sebesar 14,

Fraksi Etanol 96% Biji Koro Benguk (Mucuna Pruriens L.) Sebagai Peningkat Kualitas Spermatozoa Mencit (Mus Musculus)

Background: The examination of sperm quality is the main priority for infertility diagnosis. Based on previous study with mice, active ingredient of Mucuna pruriens L. or koro benguk (Papilionaceae), the L-dopa, may affect the quality of spermatozoa.Objective: Research was to study the effect of 96% ethanol fraction Mucuna pruriens seed on spermatozoaquality of mice exposed to 2-Methoxy ethanol. L-dopa in 96% ethanol fraction of M. pruriens seed was 14.7%.Methode: This was an experimental study using complete randomized design. Subjects were BALB/C mice (Mus musculus). Five groups served as control, 3 groups received subcutaneos injection of 2-ME as muchas 100 mg/kg.bw/day for 12 days, followed with 96% ethanol fraction Mucuna pruriens seed starting from14 mg/kg.bw/day, 28 mg/kg.bw/day, and 56 mg/kg.bw/day for 51 days.Result: The 96% ethanol fraction of Mucuna pruriens seeds are significant increase motility (p<0,01) andthe percentage of normal spermatozoa morphology (p= 0,042).Conclusion: 96% ethanol fraction of Mucuna pruriens seeds are able to increase motility and the percentage of normal spermatozoa morphology in mice exposed to 2-ME

Aplikasi Sistem Pakar Diagnosis Penyakit Ispa Berbasis Speech Recognition Menggunakan Metode Naive Bayes Classifier

ISPA (Acute Respiratory Tract Infection) is a respiratory disorder disease that can lead to a wide spectrum of diseases ranging from asymptomatic disease, mild infection to severe and deadly disease due to environmental factors. So if someone complains of respiratory disorders not necessarily just have regular respiratory problems because it could be the person has ARI disease. The role of expert systems provided in the form of an application is needed to help a person in the diagnosis of ARI disease easily and quickly. By trying to adopt human knowledge into a computer, an expert system is capable of solving problems like that of an expert. Therefore, the Application of Expert System Diagnosis of ISPA Disease Based Speech Recognition Using the Naive Bayes Classifier Method can be used to diagnose ARI disease against a person based on the conversion of the user's voice detection result. With this application the user seemed to consult a doctor / expert who treats ARI disease. The application is built based on android using Java programming language and MySQL database
