Abstract

Tujuan penelitian ini adalah mengetahui pengaruh jenis bahan pengeras dan waktu perendaman serta interaksinya terhadap mutu manisan kering kulit buah naga. Penelitian menggunakan Rancangan Acak Lengkap dengan dua faktor dan tiga ulangan. Faktor pertama jenis larutan jenuh bahan pengeras (Ca(OH)2, CaCO3 dan CaSO4). Faktor kedua adalah lama perendaman (6, 12 dan 18 jam). Hasil penelitian menunjukkan bahwa jenis larutan jenuh bahan pengeras, lama perendaman dan interaksinya berpengaruh nyata terhadap sifat kimia (kadar air, abu dan gula pereduksi) dan sensoris hedonik dan mutu hedonik untuk warna dan tekstur manisan kering kulit buah naga. Perendaman dalam larutan bahan pengeras ternyata mengeraskan tekstur, tetapi tidak merenyahkan tekstur manisan kering kulit buah naga yang dihasilkan.

Abstract

Size controlled magnetic nanoparticle (MNPs) of iron oxide were prepared in the presence of NaNO3 via co-precipitation method followed by HNO3 peptizing according to Massart’s method. The MNPs size were reduced by addition of NaNO3 in varied molarity and at different stage of process. As an end product, stable water-base colloids were formed. XRD pattern analysis using Rietveld method confirmed Fe3O4/g-Fe2O3 phase formation with nanoscale crystallite size. This crystallite size significantly decrease with NaNO3 addition from 12 nm to smaller than 8 nm, and give end-result of decreasing magnetization as measured by VSM. Langevin fitting of magnetic hysteresis curve also revealed the magnetic core size of nearly the same behaviour. TEM results show bigger value for single magnetic nanoparticle of > 10 nm and < 10 nm for MNPs without and with NaNO 3 addition, respectively. However, PSA measurement still trace a low nanoparticle agglomeration of ~ 20 nm, even after surface peptization using HNO3. A possible mechanism is proposed to explain these characteristics formation especially of the MNP’s size.

Abstract

The capital markets have been in the emerging market category for example, the Indonesia StockExchange. In connection with this condition, it has been known that the behavior of issuers andinvestors are still relatively unstable. This behavior is quite different to market conditions in othercountries, which have become the efficient market. The number of listed companies is still relativelysmall compared to the number of listed companies on stock exchanges in developed countries. Theresearch aims to measure and to find empirical evidence, the direct effect of blockholder ownershipand capital structure on company value. It will investigate and examine the mediating effect ofcapital structure on company value. The research was conducted at manufacturing company inIndonesia Stock Exchange (IDX) for five years. This research use census sampling, with number 36of companies that were analyzed with Structural Equation Modeling (SEM). The result shows directlythe blockholder ownership does not have significant effect to company value. Capital structurehas mediating effect to the relationship between blockholder ownership and company value.This finding Explains that the indirect role of capital structure can increase of company value. Inaddition, capital structure directly has significant effect to company value.

Abstract

Learning inquiry model is one that promotes learning model to be able to find problem and can solve the problem independently. Phase inquiry model there are six stages: the orientation phase, the phase of formulating the problem, proposed a hypothesis phase, the phase of collecting data, hypothesis testing phase, and the phase of formulating its conclusions. The validity of student worksheet based on the 3 specialist validation. There were two student worksheet developed, that are student worksheet 1 discussing the topic of katabolism and student worksheet 2 discussing the topic of anabolism. The research was 4-D models that are define, design, develop and disseminate stage was not implemented. Data analysis of the validation result was done theoretically and empirically. Validation results indicate that the developed of student worksheet was categorized very valid with the persentage reaches 3.65 for student worksheets 1 and 3.68 for student worksheet 2. Skill of process outcomes showed that students experience increased science of N-gain obtained 0.70 which was categorized as high. The percentage of total students who reached minimal completeness of criteria (complete) at the posttest obtained 95% with minimal completeness of criteria 75 and the completeness of indicators obtained 81,5% complete of 7 indicators at the posttest.Keywords: The Student’s Worksheet (LKPD), Inquiry Model, Process Skills, Metabolism
