Published: August 2019

Rhythm, melody, and high frequencies in Mozart’s music are capable to stimulate creativity and motivation regions of the brain and activate brain’s areas, especially the prefrontal area of the brain, which contributes to short-term memory. Listening to Mozart ‘s music can enhance concentration because it stimulates alpha brain waves which induce relaxation and peaceful mood. The objectives of this study were to determine the Mozart’s effect towards short-term memory and concentration. This is a quasi-experimental study using pre- and post-test design, performed to 30 adult women aged between 19-24 years old. The measured data were memorized words from recall memory test and duration to finish traffic jam puzzle, before and after listening to Mozart Sonata K448 for Two Pianos in D-major 2nd Movement. Data were analyzed using paired t-test with ? = 0.05.The results showed that there is a significant difference of words remembered before and after listening to music (35,43±6,70444 vs 73±4,727; p<0,01) and duration to finish traffic jam puzzle (125,60±149,939vs 53,67±69,652 seconds ; p<0,01). We concluded that Mozart’s music improves short-term memory and concentration.

Published: August 2019

Hyperuricemia is condition which blood uric acid levels increase, in men are greater than 7 mg/dL and in women over 6 mg/dL. In Indonesia the prevalence of hyperuricemia was 32% in people under 34 years and increases every year. Beside an emping from melinjo seed there is Indonesian meals made from mixture of seed, peel and leaves of melinjo, namely as sayur asem. Consumption a lot of emping can induced hyperuricemia. This study aims to assess the effect of melinjo leaves and peel extracts to reduce uric acid levels on melinjo seed hyperuricemia male rats model. Methods: Induction was performed by giving high purine diet, melinjo seed crude drug (emping) 4.5 g/kg bw. Ethanol extracts of melinjo leaves and melinjo peel were administered in 3 doses. Results: Ethanol leaves extract of melinjo (Gnetum gnemon L.) 36 mg/kg bw could decrease uric acid levels up to 61.04%, while ethanol peel extract of melinjo 13 mg/kg bw can decrease uric acid levels up to 31.25%. Conclusions: Melinjo seed crude drug (emping) could increase the bloods uric acid level in rats up to 4.65 mg/dL. Ethanol leaves and peel extracts of melinjo could decrease uric acid blood levels in hyperuricemia rats.

Authors: Jeffrey Jeffrey , Satari Mieke H , Kurnia Dikdik 
Published: August 2019

The routine and long term use of chemicals to maintain oral and dental health have the potency to result in the emergence of side effects; therefore another strategy is needed as an alternative such as using antimicrobial agents extracted from plants. The purpose of this study is to review the effectiveness of lime (Citrus aurantifolia) peel extract as an antibacterial in preventing biofilm formation. Biofilm is a component consisting of bacteria in a self-produced polymeric matrix, attached to an inert surface, alive, and can survive because of its ability to capture nutrients and withstand adverse environmental conditions. Lime peel contains flavonoids which are the largest group of polyphenol compounds that can work as antioxidants and antibacterial by denaturing bacterial cell proteins and damaging bacterial cells. Flavonoids can also inhibit glucosyltransferase (GTF) activity of Streptococcus mutans to prevent biofilm formation. Lime peel extract inhibits the formation of the activity of the enzyme Streptococcus mutans. As a conclusion lime peel extract contains compounds with therapeutic potential and has the effect of inhibiting the formation of the activity of the enzyme Streptococcus mutans so that it can be used to inhibit the formation of biofilms.

First in the Au-Te-Se-S system (where Te ≥ Se + S) quadruple chalcogenides were obtained by dry synthesis: AuX (AuTe0,7Se0,2S0,1), Au3X10 (Au3Te6Se3S, Au3Te6Se2,5S1,5) и AuX2 (AuTe1,8Se0,2, AuTe1,8Se0,1S0,1). According to the results of X-ray phase analysis, the synthetic phases of the composition AuTe1,8(Se,S)0,2 correspond to the calaverite (AuTe2). The unidentified peaks on the diffractograms belong to the new gold chalcogenides AuTe0,7Se0,2S0,1 and Au3Te6(Se,S)4. Obviously, they are synthetic analogues of compounds previously unknown in nature, found on the Gatching occurence of the Maleteuyamsky ore field (Central Kamchatka volcanic belt). The compositions of natural phases cover the intervals: 1) Au0,99-1,00Te0,70-0,71Se0,25-0,27S0,03-0,06; 2) Au2,91-3,08Te5,85-6,06Se1,57-3,66S2,63-0,44. Raman spectra of synthetic and natural gold chalcogenides with a similar composition have identical character.

Analisis hubungan untuk suatu variabel respon yang tidak berditribusi normal adalah dengan menggunakan metode Generalized Linear Model (GLM). Variabel respon diasumsikan berditribusi dari keluarga eksponensial, seperti distribusi gamma. Variabel respon pada penelitian ini adalah data jumlah jemaah haji di Provinsi Aceh dengan 22 variabel penjelas diantaranya meliputi agama, ekonomi, kependudukan, dan pendidikan. Penelitian ini betujuan untuk mendapatkan GLM jumlah jemaah haji di Provinsi Aceh dengan pendekatan distribusi gamma. Hasil hipotesis menunjukkan bahwa jumlah jemaah haji, ongkos naik haji, persentase penduduk Islam, jumlah ustad, jumlah pengangguran, persentase pengeluaran untuk makanan penduduk tidak miskin, dan persentase pengeluaran untuk makanan penduduk miskin berhubungan terhadap jumlah jemaah haji di Provinsi Aceh.

The analysis for a non normal distributed dependent variable is using the Generalized Linear Model (GLM) method. The dependent variable is assumed to be contributed from the exponential family, such as the gamma distribution. The dependent variable in this study is the hajj group value in Aceh Province with 22 independent variables including religion, economy, population, and education. This study aims to obtain the GLM the hajj group value in Aceh province with a gamma distribution approach. The results of the hypothesis show the hajj group value, the cost of hajj, the percentage of Muslim population, the number of ustad, the number of unemployed, the percentage of expenditure for food of the non-poor, and the percentage of expenditure on food of the poor corresponds to the hajj group value in Aceh Province.

Telah dilakukan penelitian mengenai pengaruh konsentrasi doping karbon pada lapisan tipis TiO2 yang ditumbuhkan dengan metode spray terhadap struktur kristal dan morfologi TiO2. Hasil karakterisasi SEM menunjukkan bahwa penambahan doping karbon dapat meningkatkan ukuran butir. Lapisan TiO2 doping karbon 8% diperoleh ukuran butir terbesar adalah 1.35 μm, sedangkan ukuran tekecilnya adalah 0.45 μm. Sementara itu, untuk lapisan tipis TiO2 didoping karbon 15% memiliki ukuran butir terbesar yaitu 1.76 μm dan terkecil 0.9 μm. Hasil XRD menunjukkan seluruh puncak difraksi lapisan tipis TiO2 dengan doping karbon 8% dan 15% merupakan TiO2 anatase. Ukuran kristal lapisan TiO2 didoping karbon 8% diperoleh sebesar 638,08 Å dan untuk pendopingan 15% karbon ukuran kristal lapisan tipis TiO2 adalah 638,09 Å, hal ini menunjukkan ukuran kristal kedua sampel tidak mengalami perubahan yang signifikan.

TiO2 thin film with carbon doping has been successfully grown by spray method. The research on the effect of carbon doping on crystal structure and morfology of TiO2 has been prepared by varying carbon concentration (8% and 15% carbon). Analysis of SEM showed that the addition of carbon may increase the grain size. Thin film of TiO2 doped carbon 8% has the largest grain size 1.35 μm, while the smallest grain size is 0.45 μm. Meanwhile, for thin film TiO2 doped carbon 15% has the largest grain size 1.76 μm and smallest 0.9 μm. The XRD results showed the entire diffraction peak of thin film TiO2 doped carbon 8% and 15% were TiO2 anatase. The crystal size of thin film TiO2 doped carbon 8% was obtained at 638.08 Å and for thin film TiO2 doped carbon 15% the crystalline size of TiO2 thin film was 638.09 Å, this shows that the crystal size of both samples did not change significantly.
