Abstract

PT. Sango Ceramics Indonesia sudah dikenal di seluruh dunia, karena telah mengekspor hasil produksinya berupa barang pecah belah. Kegagalan produksi yang dialami oleh perusahaan masih tinggi yaitu sebesar 3,1% dari total produksi sedangkan target cacat yang diinginkan perusahaan sebesar 2%. Dalam penelitian ini menggunakan metode Failure Mode and Effect Analysis (FMEA) dan metode Fault Tree Analysis (FTA) untuk mengidentifikasi kegagalan yang terjadi dan memberikan solusi pencegahan. Tujuan penelitian ini adalah Mengidentifikasi jenis-jenis cacat yang terjadi pada produk piring di lantai produksi piring PT Sango Ceramics Indonesia berdasarkan pada hasil penelusuran studi literatur dan deep interview dengan para pegawai dari PT. Sango Ceramics Indonesia, mendapatkan resiko kegagalan proses produksi terbesar dalam nilai RPN (Risk Priority Number ) dari metode FMEA yang kemudian dianalisis kembali menggunakan metode FTA dan menentukan usulan perbaikan yang diperlukan berdasarkan analisis defect yang terjadi pada produk piring. Berdasarkan pengolahan data dengan menggunakan metode FMEA dan FTA dapat mengidentifikasi moda kegagalan yang terjadi pada proses pembuatan piring di PT Sango Ceramics Indonesia.r ABSTRACT PT. Sango Ceramics Indonesia is already known throughout the world, because it has been exporting its products such as glassware. Production failures experienced by companies is still high at 3.1% of total production while the company wants the target of defect is 2%. In this study using Failure Mode and Effect Analysis (FMEA) method and Fault Tree Analysis (FTA) method to identify the failure and find the solution. The purpose of this study are identifying the types of defects that occur in the product plates on the production floor of PT Sango Ceramics Indonesia is based on a literature search results and deep interviews with the employees of PT. Sango Ceramics Indonesia, risk failure of the largest production processes in the value of the RPN (Risk Priority Number) from the FMEA method then reanalyzed using the method proposed FTA and determine the necessary improvements based on the analysis of product defects that occur. Based on the data processing by using FMEA and FTA can identify failure modes that occur in the process of making the plate in PT Sango Ceramics Indonesia.

Abstract

Since many corporate’s disclosures are claimed to be more value relevant and more informative, this research examines if the earnings response coefficient changes by projections and corporate social responsibility (CSR) disclosures. Data were obtained from companies incorporated in the LQ 45, August 2014 - January 2015 period. This research used two models, model 1 (without control variables) and model 2 (with control variables) that test using Ordinary Least Squares Regression. On model 1, the F test results indicate that projections and CSR disclosures simultaneously have significant effect on the ERC. While the t test results showed that partially, projections have negative significant effect on ERC. This results reflect that diclosure of projections aim to lower asimmetry information because of corporate’s prospect uncertainty. CSR disclosures have no significant effect on ERC but the coefficient was negative, according to the research hypothesis. On model 2, both the F test  and t test results showed that the projection information, CSR, capital structure, and company growth simultaneously and partially have no significant effect on the ERC. Keywords: projections, corporate social responsibility, earning respon coefficient

Abstract

Cocor bebek (Bryophyllum pinnatum) has been proven as analgesics for relief of acute pain. Flavonoid is one of the compounds in Bryophyllum pinnatum which is potentially developed as analgesics for the treatment of chronic inflammatory pain. This study was conducted to determine the effect of ethanolic leaf extract of Bryophyllum pinnatum as attenuation of thermal hyperalgesia in rats with chronic inflammatory pain. This study used a completely randomized design with complete Freund’s Adjuvant/CFAinduced chronic inflammatory pain in wistar rats, at the first day. Thirty rats were divided into 5 (five) groups (n = 6), consisting of a positive control (ketamine 10 mg/kg bw), negative control (CMC Na 0.5%), and three treatment groups of ethanolic leaf extract of Bryophyllum pinnatum with doses of 200, 400 and 600 mg/kg bw. The extract was given twice a week for four weeks,at day-3 and day-6. The effect of the treatment on the attenuation of thermal hyperalgesia was investigated by using hot-plate at day-7, day-14, day-21 and day-28 to measure latency and subsequently, the percentage of the increase in latency was calculated. Analysis of Variance (ANOVA) was employed to analyze the data and continued by Least Significance Different test (LSD). The ethanolic leaf extracts of Bryophyllum pinnatum at the doses of 200, 400, and 600 mg/kg bwhad effect of the attenuation of thermal hyperalgesia by increasing latency by 3.18, 4.33 and 6.12 seconds, respectively. The optimum dosage as antihiperalgesia was 600 mg/kg bw, with latency was increased to twice than those of negative control group.

Abstract

The purpose of the study was to assess the effect of marketing strategy of the company’s performance and the role of competition environment in moderating the marketing strategy of the company’s performance. The MRA (Moderated Regression Analysis) was used as the analyzing method. The result shows that there is a significant and positive effect of the marketing strategy of the company’s performance (r = 0, 912), and a significant and positive effect of the logistics competition environment of the company’s performance (r = 0, 955). The role of competition environment in moderating the negative relation between marketing strategy and company’s performance since the competition environment comes from outside and could threaten the company’s marketing and decrease the performance.

Abstract

Synthesis of activated carbon from coconut shell waste with ZnCl2 activation using microwave heating have been carried out. Coconut shell consists of 36.51% lignin, 33.61% cellulose and 19.27% hemicellulose which causes it can be used as a precursor in the synthesis of activated carbon. The activated carbon was further characterized using Scanning Electron Microscope (SEM), Fourier Transform Infrared Spectrophotometer (FTIR) and NOVA Gas Sorption Analyzer-Quantachrome and used for the adsorption of methyl violet in aqueous solution with variation of pH, contact time and concentration of solution. The result showed that the pore of activated carbon was larger than that of the char. The optimum adsorption occurred at pH 3 and the equilibrium time was reached after 180 minutes. The Langmuir equilibrium model was more appropriate than the Freundlich equilibrium model. While the kinetics model analyzed using pseudo first order, pseudo second order, internal diffusion and external diffusion indicated that the pseudo second order was most suitable for the adsorption of methyl violet by coconut shell activated carbon.

Abstract

Children are part of the community, they have the same rights as other communities to be protected and respected. Any State anywhere in the world is obliged to give adequate attention and protection to the rights of the child, which include civil, economic, social and cultural rights. However, it seems that the status and rights of the children when viewed from a juridical perspective have not received serious attention either by the government, law enforcers or the public in general and are still far from what should be given to them. This condition is compounded by the weak implementation of the law on the rights of the child committed by law enforcement officers themselves. The rights of the child shall be respected by everyone. One of them is in the punishment system which until now sometimes still treats the children involved as perpetrators of such crimes as perpetrators of criminal acts committed by adults. The child is placed in a position as a criminal offender who deserves the same punishment as an adult and applies in Indonesia. Whereas punishment itself is more oriented to individual perpetrators or commonly referred to as individual responsibility (personal Individual Responsibility) where perpetrators are viewed as individuals who are able to take full responsibility for the deeds it undertakes. While the child is an individual who has not been able to fully realize the actions / actions that he did, this is because the child is an immature individual in thinking. Without realizing it, of course, can cause a great psychological impact on the child that ultimately affects the mental and mental development of the child.
