Published: November 2019

Abstract
In this study, we propose approximate solution of the time-fractional diffusion equation (TFDE’s) based on a quarter-sweep implicit finite difference approximation equation. To derive this approximation equation, the Caputo’s time fractional derivative has been used to discretize the proposed problems. By using the Caputo’s finite difference approximation equation, a linear system will be generated and solved iteratively. In addition to that, formulation and implementation the Quarter-Sweep Gauss-Seidel (QSGS) iterative method are also presented. Based on numerical results of the proposed iterative method, it can be concluded that the proposed iterative method is superior to the FSGS and HSGS iterative method.

Abstract
The use of hormones as one of the therapies is increasingly prevalent at this time, there are many uses obtained by hormone therapy such as preventing miscarriage in pregnant women or as a contraceptive. It was reported that the contraceptive hormone was the most used method by women compared to other contraceptive methods. Diethylstilbestrol (DES) is one of the synthetic estrogen hormones that is useful as hormone replacement therapy. However, the use of DES can also trigger abnormal cell growth that will develop into cervical cancer. This study was conducted to analyze the effect of DES on the p53 gene expression and caspase-3 levels. P53 is a cancer suppressor gene and caspase 3 is a gene that plays a vital role in the process of apoptosis. The method of this study was a post-test design in vivo experiment in animal model which was induced with doses of DES 1500 μgram / BB at 3 days of age after birth, then observed at 35 days. The results showed that there was a significant decrease in p53 gene expression and caspase-3 between DES-induced animals models compared with DES-uninduced with p-value = <0.05. Thus, it was concluded that DES has given to 3-day-old models animals and evaluate at the 35-days-old effect on decreasing p53 gene expression and caspase-3 levels.

Abstract
In the face of increasingly competitive competition in the hospital industry, RSU managers are required to be able to develop strategies, policies or new breakthroughs related to improving the quality of their services, through improving the characteristics of hospital services, which focus on patient needs, so that the risk of errors or discrepancies between service characteristics that are enhanced by what the patient wants can be avoided or minimized. From the results of research conducted there are 21 variables of patient needs from a health service at the Government General Hospital (RSU). Whereas the patient’s research on the service quality of the Government Hospital is 1 variable that has fulfilled the needs of patients, namely that they are satisfied with the quality of hospital services. Variable is the state and completeness of modern medical facilities. Whereas for other variables there are gaps so that they cannot meet patient expectations until the highest quality limit is very satisfied, it is necessary to have a direction of improvement. To obtain the suitability, the technique used to improve the characteristics of the service is the application of the QFD method. The QFD method in this study is in the form of a quality service matrix at the Government General Hospital. From the HOQ matrix, the service quality of the Government Hospital is obtained from the input of the Government Hospital/management that there are priority variables needed to improve their quality, which is generally the patient’s needs related to the recovery of patients, including the knowledge and abilities of doctors, medicines the treatment given in the healing of patients, the service of examination, treatment and care that is fast and precise, guarantee of security and trust in the services provided and the completeness of the readiness and cleanliness of the equipment used. So there are 33 service quality characteristics prioritized for further improvement, with the main priority being patient recovery.

Published: November 2019

Abstract
One of the functions of the supply chain system is to provide the right products and services, at the right place, at the right time, and at the desired conditions by still providing optimal contribution to the company. Supply Chain Management is the management of various activities in order to obtain raw materials, followed by transformation activities so that they become products in the process, then become finished products and forwarded to delivery to consumers through the distribution system. The purpose of this study is to improve the welfare of fishermen as fish producers in order to be given equal opportunities in competing to get consumers directly, as well as to provide convenience to consumers who buy fish in accessing information on the location of fish marketing institutions and the selling price of fish. The fish marketing system that has been going on so far have to pass several stages. With such marketing system, consumers do not buy directly from producers. This can be caused by a lack of consumer information on the location and location of fish producers in their environment. By purchasing directly from producers, it can also increase the economy of fishermen as fish producers. Based on this reason, this research creates a model to cut the supply chain of fish sales distribution. The method used is the Supply Chain Operation Reference (SCOR) model and rule based and action Research. The result of this study is the use of the Supply Chain Management model in the One Stop Fish Marketing Information System, which is expected that fishermen will have their own target markets that can directly buy fish from fishermen as the main producers of fish.

Abstract
We have carried out the experiments on coagulation and precipitation of silica from the separate of Verkhne-Mutnovsky geothermal electric power plant (Mutnovskoe hydrothermal field). Silica precipitation from the water solution was conducted in two ways: by adding slaked lime CaO and by electrocoagulation treatment on aluminium electrodes. Silica precipitation with addition of slaked lime was carried out under laboratory conditions at the temperature of 20 and 96 °C. Colloid and monomeric silica concentrations, solution pH, flakes sizes and physical-chemical properties of material precipitated with different quantities of added lime were determined. We also carried out series of experiments on solution treatment of mixed type: addition lime with freshly precipitated flakes, and addition lime with sea water. In the experiments on electric coagulation, current intensity and distance between electrodes were changed. Dependence of silica concentration on treatment duration was studied. Quantities of electric energy and anode aluminium consumed for reducing of silica concentration to a certain level were obtained. The results of our experiments can be used for developing of technological scheme of silica precipitation and utilization optimal for Verkhne-Mutnovsky geothermal electric power plant.

Electrochemical characterization of gold mining wastewater for recovery of mercury using electrochemical method
Authors: Rahmawati A I , Widayatno T 
Published: November 2019

Abstract
An experimental study to determine optimum operating conditions for mercury recovery from gold mining wastewater has been conducted. Electrochemical characterization of gold mining wastewater was carried out by using steady-state polarization experiment in a batch system. The polarization curves obtained were then utilized to determine the optimum operating conditions. The polarization experiments were conducted by an electrochemical cell with two electrodes of copper (Cu), carbon (C), or stainless steel (SS) and an electrolyte solution of the wastewater. Variations of electrodes used were pairs of copper (Cu), carbon (C) and stainless steel (SS) which were arranged randomly. To obtain the polarization curves, the electrical potentials between 0 V and 3 V were applied and its corresponding currents were recorded at an interval potential of 0.1 V. The highest current density was achieved on electrode pairs of stainless steel-carbon (SS-C) and carbon-carbon (C-C). This is an early indication that the most optimum electrode pairs for mercury recovery possibly are SS-C and C-C. EDX analysis confirmed the presence of mercury in the deposited materials, this leads to a conclusion that mercury can be deposited on to carbon electrode from the wastewater using electrochemical method which then eventually it can be recovered.
