Published: April 2019

Several types of medicines for pediatric patients are not commercially available in appropriate dosage forms. While divided powder resulted from compounding process is an alternative to address this problem, the dosage accuracy is still profoundly a major issue. This research was aimed at comparing student’s ability prior to and after taking compounding practical work and analyzing weight accuracy of divided powders compounded by students. This research was designed as a pre-post study. Students who were taking compounding practical work (for 12 weeks) in 2017 were asked to fill a prescription contained divided powders in the beginning and the end of the semester, given enriched learning material of compounding technique videos and feedback as evaluation of their pretest results. The data is presented in the form of a percentage, while differences between pretest and post-test are compared utilizing Wilcoxon test. This study suggests that there was a significant increase of students’ ability in calculating the amount of each ingredient required to fill the prescription, choice of label color, approximating the beyond-use date, folding the divided powders, and making a copy of the prescription. However, there was a small number of students (15.3%) whose divided powders they have dispensed were in the allowed weight range. This study documents the need for quality assessment of medications prepared by students quantitatively and this assessment serves as a parameter of student performance.

Published: April 2019

Patients with diabetes mellitus (DM) are patients with a low level of treatment adherence. Low adherence is often the cause of treatment failure, so the risk of complications is higher and can affect the quality of life of patients. This study aimed to determine the relationship between treatment adherence to clinical outcomes and the quality of life of patients with type 2 DM. This study used a cross sectional design involving patients with type 2 DM who met the inclusion and exclusion criteria in three health centers in Bantul, Yogyakarta. Data on patient medication compliance was obtained using medication adherence report scale questionnaire (MARS-5), patient quality of life data using Short-Form 6 Dimensions questionnaire (SF-6D), data on fasting blood glucose levels (GDS / GDP) from medical records, socio demographic data obtained from respondents and medical records. The relationship between the level of adherence to clinical outcomes using Chi-square analysis while the relationship between the level of adherence to quality of life using Spearman Rho analysis. The total number of respondents involved was 179 patients, the majority had a low level of adherence (57%), clinical outcomes that had not been achieved (68.7%), and the average utility score was high (0.816). There was a relationship between medication adherence to clinical outcomes (P = 0.002; OR = 2.875). Similarly, between adherence to quality of life, there is a significant relationship (P = 0.006) with a weak correlation level (r = 0.204). Therefore, patients and Health professionals, especially pharmacists, need to pay attention to medication adherence to achieve optimal clinical outcomes and a better quality of life.

Pharmaceutical industry has a role to produce affordable and good quality medicines by implementing good supply chain. The purpose of this study was to identify the role of inventory control, storage and distribution facilities in the pharmaceutical industry in supporting drugs availability in the JKN era. This is a descriptive research with qualitative method and uses purposive sampling. Data was collected in depth interview with employees from the PPIC and SCM in Pharma A, Pharma B, Pharma C and Pharma D that collaborated with BPJS Kesehatan and become drug providers in e-catalogue tender. Data analysis consisted of making interview transcripts, interpreting data, and triangulation. The results of the analysis showed that inventory control has an influence in the pharmaceutical industry in supporting the drugs availability due to a mismatch between demand and need, thereby increasing the occurrence of stock over or stock out. Facilities of storage has an influence in the pharmaceutical industry in supporting the drugs availability due to overload storage facilities so that the storage method was not optimal and has to pay other costs to rent warehouses. Distribution has an influence in the pharmaceutical industry in supporting the drugs availability because the costs for distribution must reach a minimum order to be distributed and the choice of transportation modes for distribution may be increased the lead time that caused the drug vacancies.

Published: April 2019

In 2013, Ministry of Health, Republic of Indonesia, launched a new change to drug procurement system, namely e-catalogue, to ensure the availability and affordability of medicines. This system replaces the previous auction drug procurement system. The purpose of the change into e-catalogue system is to facilitate the drug procurement in hospitals without the need to conduct complex negotiation with producers, to reduce the occurrence of mark-ups or inflating drug prices, to equalize drug prices, to support BPJS (Badan Penyelenggara Jaminan Sosial) activities, and to prevent difficulties in drug distribution in all regions in Indonesia. This study aims to get an overview and magnitude of the impact of e-catalogue application on changes in the price of drugs registered and not registered in e-catalogue at Jakarta Islamic Hospital Cempaka Putih. This research is a longitudinal time series study. The data collection was conducted retrospectively in the period of 2011-2015 taken from procurement data, purchase invoices, and e-catalogue prices from hospital pharmacy installation, which were then categorized based on similar drugs in the hospital. The result shows a decrease in the price of drugs on both e-catalogue drugs (generic, trade names and patents) and non e-catalogue drugs (generic, trade names). On the class of therapy, the biggest price reduction occurred in e-catalogue medicine, such as in antineoplastics, intravenous solution, diabetes, Anti-ashma & COPD, and psycholeptics therapy. Meanwhile, on the category of non e-catalogue, price reduction occurred in systemic antibacterials, antineoplastics, analgesics, cardiac theraphy, and A-acis A-flat A Ulcerants therapy. The magnitude of drug prices reduction ranges from 1% to more than 90% both on e-catalogue drugs and non e-catalogue drugs. On the e-catalogue drugs, the highest price reduction (82.36%) occurred in generic and patent drugs, while on non e-catalogue drugs, reduction occurred in drugs with trade names. The price reduction trend in drug prices based on both type of drugs and therapy class shows a significant decrease in drug prices in the period after the implementation of e-catalogue at Jakarta Islamic Hospital in Cempaka Putih, with a decrease of more than 80%.

Investigación teórica, dogmática, hermenéutica, doctrinal y empírica de las ciencias jurídicas
Authors: Valencia Grajales José Fernando , Marín Galeano Mayda Soraya
Published: April 2019

Las ciencias del derecho han construido con el tiempo una serie de herramientas de carácter empírico que dejan atrás el área dura del derecho, o lo que se denomina la teórica, dogmática, hermenéutica y la doctrina de las ciencias jurídicas; lo anterior no a causa de la falta de material normativo para ser analizado, sino al desconocimiento de los mismos juristas, que pareciera que perdieron el rumbo del iusnaturalismo, el iuspositivismo, el realismo, el trialismo, los pluralismos o paralelismos. Olvidando las escuelas, como la exegesis, la glosa, las pandectas, los posglosadores, la histórica o la realista. Dicho olvido ha permitido la proliferación de investigaciones empíricas, casuísticas o de línea jurisprudencial, lo que ha derivado en el menosprecio del estudio de los principios, valores y el ethos del derecho. Es por ello que, en la presente investigación, se pretende realizar un pequeño recorrido histórico, a manera de marco teórico; luego se evidenciará la necesidad de la teoría jurídica y, finalmente, se intentarán algunas reflexiones en torno a la investigación teórico-jurídica.
Desarrollo jurisprudencial del derecho al agua en Colombia. Protección en casos de exclusión del sistema de prestación de servicios públicos de acueducto y alcantarillado por falta de infraestructura
Authors: Botero Mesa María
Published: April 2019

El presente artículo busca exponer el desarrollo judicial del derecho al agua, en casos de exclusión de la prestación de los servicios públicos de acueducto y alcantarillado por falta de infraestructura, a partir de la construcción de las líneas jurisprudenciales que han consolidado al respecto tanto la Corte Constitucional como el Consejo de Estado. Para lograr este cometido se sigue la metodología jurídica propuesta por el doctrinante Diego E. López Medina, en su publicación El derecho de los jueces. Obligatoriedad del precedente constitucional, análisis de sentencias y líneas jurisprudenciales y teoría del derecho judicial. Los hallazgos del trabajo muestran que ambas cortes han sostenido, en el tiempo, decisiones de reconocimiento y protección del acceso al agua para consumo humano como un derecho fundamental, tanto en su manifestación colectiva como en la individual. Las características del precedente sentado, su vigencia en el presente y el rigor metodológico para su estudio, se encuentran descritas en el cuerpo del siguiente texto.
Descentralización en Bolivia y Uruguay. Una aproximación desde la teoría de la gobernanza
Authors: Sánchez Díaz Iván Mauricio
Published: April 2019

Desde las teorías políticas, sociológicas, jurídicas y sociales se ha intentado responder a la pregunta: ¿en qué medida el Estado y la sociedad, y la relación entre ambos, en un nuevo contexto político y de desarrollo, influye en los procesos de descentralización? Con el fin de comprender el paso de la centralización a la descentralización, como modelo de gobernanza que terminó favoreciendo los gobiernos de izquierda de América Latina, durante los primeros años del siglo XXI, imponiendo la “gobernanza radical” y profundizando la democracia, lo que dio como resultado el autoritarismo, como mecanismo de las élites para contrarrestar dichos hechos.

Con esta experiencia, se propone un modelo asociativo con rotación de funciones, una capacitación basada en la educación popular, el fortalecimiento de las unidades socioeconómicas y la conciencia política, préstamos a bajos intereses, de acuerdo con la capacidad de pago, evitando el endeudamiento excesivo, ahorro programado, fondos comunes y planes exequiales.
Diálogos de paz Gobierno-ELN y las encrucijadas para una Paz completa en Colombia
Authors: Ortiz Lancheros Carlos Alfonso
Published: April 2019

El escenario de diálogo entre el Gobierno Nacional y el Ejército de Liberación Nacional (ELN), a partir del 7 de febrero de 2017, dio señales esperanzadoras para que una Paz completa sea posible. Sin embargo, esto no puede ocultar algunos elementos de análisis que se constituyen en retos para este nuevo intento de conversaciones con los “elenos”, séptimo desde la administración del expresidente César Gaviria Trujillo (1990-1994) al presente gobierno de Juan Manuel Santos (2014-2018). El apartado se pregunta por las posibilidades y limitaciones que presentan estos diálogos, entendiéndolos como un proceso distinto del Gobierno-FARC-EP que construye una estructura de oportunidades particulares, en relación con las del eln. Para ello se abordará desde el enfoque de análisis de coyuntura (Ramírez, 1993), comprendiendo los juicios de la mesa de diálogo y el lugar de la participación social, configurando un posible escenario marcado por la incidencia de la sociedad civil y el reto institucional que ello impone.

Authors: Ibrahim Arsmah , Abu Bakar Zainab , Othman Nuru’l–‘Izzah , Ismail Nor Fuzaina
Published: April 2019

Manual marking of free-response solutions in mathematics assessments is very demanding in terms of time and effort. Available software equipped with automated marking features to mark open-ended questions has very limited capabilities. In most cases the marking process focuses on the final answer only. Few available software are capable of marking the intermediate steps as is norm in manual marking. This paper discusses the line-by-line marking performance of the n_gram string similarity method using the Dice coefficient as means to measure similarity. The marks awarded by the automated marking process are compared with marks awarded by manual marking. Marks awarded by manual marking are used as the benchmark to gauge the performance of the automated marking technique in terms of its closeness to manual marking.
Efficient Edge Detection Using Fuzzy Heuristic Particle Swarm Optimization
Authors: Abdul Khalid Noor Elaiza , Manaf Mazani , Aziz Mohd Ezane
Published: April 2019

This paper presents a hybridization of Particle Swarm Optimization (PSO) and Fuzzy edge detector. The edge detector is used as the initial population and as the objective function. The purpose of hybridizing the algorithm is to create an optimized edge detector. Classical Fuzzy Heuristics (CFH) detects thick edges. These thick edges need to be optimized to obtain a thin line. In this research the PSO is used to optimize the edge detection detected by the CFH algorithm and it is referred to as FHPSO. The test images are radiographs images of the metacarpal. These images have been used, because there is a need to detect strong and thin edges. Radiograph images are noisy in nature, which makes it difficult to measure the cortical thickness, the cortical outline of the inner cortical and outer cortical of the long tubular bone. The outer cortical edges are considered to be the strong edges due to high discontinuity values and the inner cortical edges are considered weak edges due to low their discontinuity values. The performance of FHPSO in detecting edges has been shown to be quite efficient.
Solving Robot Path Planning Problem Using Ant Colony Optimisation (ACO) Approach
Authors: Abu Bakar Nordin , Abdul Kudus Rosnawati
Published: April 2019

Learning is a complex cognitive process; thus, the algorithms that can simulate learning are also complex. The complexity is due to the fact that little is known about the learning process that can be simulated in a machine. In this study two methods have been chosen to navigate a simulated robot to a target point; namely, Ants Colony Optimisation (ACO) and the Fuzzy Approach. The focus of this paper is primarily the ACO method and the Fuzzy Approach is used as a comparative benchmark. Three scenarios were designed: the Big Hall, the Wall Following and the Volcano Challenge. These experimental scenarios represent the respective navigation frameworks found in the literature used to test learning algorithms. The results indicate that the ACO’s performance is inferior to the Fuzzy approach; justification for this has been discussed in relation to previous research in this area. Some future work to investigate this phenomenon further and improve the performance of the ACO algorithm is also presented.
Re-Aging Heat Treatment to Stress Corrosion Cracking Resistance on Al-Zn-Mg-Cu Alloy
Authors: Deraman Rasdi , Aziz Mohd Rozaiman , Yaakob Yusli
Published: April 2019

The Al-Zn-Mg-Cu alloy is classified as a high strength to weight ratio material and is widely used in the aerospace structures. This alloy is susceptible to severe localized corrosion induced by heat treatment. The objective of this study is to elucidate alternative heat treatment techniques, which reduce the alloys susceptibility to Stress Corrosion Cracking (SCC). A series of different heat treatments have been performed in the Al-Zn-Mg-Cu alloy using cube shaped and C-ring specimens that had been T6- and T7-tempered and undergone Retrogression and Re-aging (RRA) heat treatments. The specimens were exposed to hardness testing, optical testing and immersion testing in a corrosive environment. The effectiveness of the heat treatments was evaluated with respect to improvements in corrosion resistance and the longevity of the Al-Zn-Mg-Cu alloy. The susceptibility of the Al-Zn-Mg-Cu alloy to SCC has been directly related to the precipitation of MgZn2 particles at the grain boundaries. Precipitation hardening of Al-Zn-Mg-Cu alloy increases the hardness of the material, but increases susceptibility to SCC failure. RRA treatment greatly improved the corrosion resistance and longevity of the alloy combined with minimal strength reduction.
Implementation of E-rental Housing via Generic Notification Message Through Mobile Phone
Authors: Ahmad Suzana , Sakamat Norzehan , Mohd Idris Noorazida
Published: April 2019

As UiTM increases its student enrollment, the number of students seeking accommodation inherently increases. This is particularly true with respect to off-campus accommodation since the number of students that the residential colleges can accommodate is limited. Unit Kebajikan NR (Non Resident) under Hal Ehwal Pelajar (HEP) has been set up to assist students looking for suitable accommodation. The unit is still implementing a manual- and paper-based processing to capture information. This is both highly inefficient and time consuming. This study provides a convenient platform for students and landlords to share updated information about available rental accommodation. A prototype web-based rental housing system, which is based on generic notification messaging, has been developed. This online system offers services to students seeking rental accommodation around the UiTM campus. Home owners can use this system to advertise their properties without the use of paper based forms or placing advertisements in newspapers, which is common practice. Communication between potential landlords and tenants can be done interactively via SMS once both parties have registered with the system. A System Development Life Cycle (SDLC), an iterative development, has been adopted for the purposes of evaluating this study. This research has the potential to aid in the development of an effective means by which accommodation for students and essentially any potential rentees can be found and attained.
Characterization of MPI Communication Primitives on a Heterogeneous Cluster
Authors: Ahmad Siti Arpah , Mohamed Said Mohamed Faidz , Mohamed Ramli Norazan , Taib Mohd Nasir
Published: April 2019

This paper focuses on the performance of basic communication primitives, namely the overlap of message transfer with computation in the point-to-point communication within a small cluster of four nodes. The mpptest has been implemented to measure the basic performance of MPI message passing routines with a variety of message sizes. The mpptest is capable of measuring performance with many participating processes thus exposing contention and scalability problems. This enables programmers to select message sizes in order to isolate and evaluate sudden changes in performance. Investigating these matters is interesting in that non-blocking calls have the advantage of allowing the system to schedule communications even when many processes are running simultaneously. On the other hand, understanding the characteristics of computation and communication overlap is significant, because high- performance kernels often strive to achieve this, since it is both advantageous with respect to data transfer and latency hiding. The results indicate that certain overlap sizes utilize greater node processing power either in blocking send and receive operations or non-blocking send and receive operations. The results have elucidated a detailed MPI characterization of the performance regarding the overlap of message transfer with computation in a small cluster system.

Authors: Mardawati Efri , Trirakhmadi Andi , Kresnowati MTAP , Setiadi Tjandra
Published: April 2019

Xylitol is a natural sugar that has the sweetness level similar to sucrose, but has lower calorie. It is an important sugar alternate for diabetics people. Reduction of xylose is a normally method to produce the xylitol. It Conducted via chemical hydrogenation of xylose at high pressures and temperatures by reacting pure xylose with hydrogen gas using a metal catalyst. This process requires pure xylose as the raw material. Alternatively, the reduction process can be carried out via fermentation. This process does not require high purity of xylose as the raw material, and thus the oil palm empty fruit bunch (EFB) hydrolysate, without any prior pretreatment, can be used.  In order to scale up the xylitol production via fermentation, kinetic study of xylitol fermentation including growth and xylitol formation kinetic using the synthetic xylose as substrate will be required.  Data used in the kinetic model development were obtained from series of batch fermentations of Debaryomycess hansenii ITB CCR85 varying the initial xylose and glucose concentrations. Yeast growth could be sufficiently modeled using the Monod kinetics, whereas xylitol production could be reasonably well modelled by Luedeking Piret kinetics.

Increased internet usage and fast-paced consumer’s demands have created business opportunities, including online food delivery services. However, competition with similar national-scale businesses allegedly contributed to the decline in the number of XYZ company orders, one of the food-delivery service providers in Yogyakarta. Therefore, this study aimed to identify the need’s attributes of the daring food delivery service consumers, to find out the service-quality satisfaction level, and to determine the technical requirement for improving the delivery service. The combination of Servqual and Quality Function Deployment (QFD) were then used to reach the research goals. The online survey instruments, which were borrowed from the previous studies and adapted for this study, were distributed from June 2016 to February 2017 to more than 700 XYZ’s consumers, with the number of respondents who answered as many as 213 peoples. Cronbach’s Alpha, the most common test for multiple Likert questions in a survey, was then used for analyzing the collected data. The result shows that order conformity; politeness and friendliness of messengers and administrative workers; cleanliness of food box; a good conditionof received ordered food; and affordable delivery costs are the top five attributes of consumer needs. Meanwhile, the top five observed technical requirements are the provision of skills training to messengers and administrative workers; periodic evaluations of service performance; the regular addition of food outlet members; providing map feature on the company website, and provision of ordering applications.  The identified requirements can benefit local food delivery service providers in competing with national scale competitors and adapt to disruptive age.

Mozzarella cheese is a food which is very risky to the growth of microorganisms since it has high water content by 54.1%. One way to overcome that problem is to identify and analyze the risks found in the production process of mozzarella cheese. Therefore, the researchers examined the identification and risk analysis of mozzarella cheese production process by conducting a case study in CV XYZ. The methods used were Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA). The results revealed that there were 11 risks from 8 steps of the production process. Of the 11 risks, the risks which were included in the critical risks were the risk of contamination during the curd clotting process, low-quality of milk, severe stretcher machine damage, and overly acidic cheese taste. The result of quantitative analysis of FTA indicated that the risk probability during mozzarella cheese production process was 0.110 or the risk was 11%. The probability with the highest value was the probability of contamination risk during the curd clotting process by 0.095. It indicated that contamination during the curd clotting process was the most probable risk in the future. The proposed recommendations for improvement are devising Standard Operating Procedures (SOPs) and Sanitation Standard Operating Procedures (SSOP) based on the company's condition and it should be implemented properly. Then, improving communication with suppliers is also needed so that the company will always get high quality raw materials. Keywords: Qualitative Analysis, Quantitative Analysis, Dairy Product, Failure Mode and Effect Analysis, Fault Tree Analysis

Xylanases are highly exploited enzyme in industries, including food and chemical industry. Xylanases can be utilized in catalyzing the endohydrolysis of 1,4-β-xylosidic linkages in xylan, lignocellulosic component to produce xylose-monomer. This research aims to optimize xylanase production from alternative substrate, corncob. Corncob contains 41.17% of hemicellulose, polymer of xylan. Xylanases are produced through solid state fermentation by Trichoderma viride. Ratio between substrate and moistening solution was 0.63 g/mL with fermentation temperature 32,8OC. Variables varied include incubation time and pretreatment (using autoclave, ozonation, combination of ozonation and autoclave, also without pretreatment). Xylanase activity was measured by DNS method using 1% of xylan as substrate standard. The result showed that the best incubation time is 36 h with 14403.8707 U/mg protein for specific xylanase activity by using autoclave as pretreatment.  Ozonation pretreatment process can increase the enzyme activity of xylanase.

This research aims to identify current condition and rules of lean manufacturing (LM) implementation in Agro- Small and Medium Enterprises (SMEs). The current condition aspects are identification of waste, LM techniques and methods, the reason and barriers on LM implementation in SMEs. Exploring the behavior of SMEs on implementing LM which supporting to generate productivity and efficiency on production system are important to be identified. Initially, LM concept are implemented in manufacturing industry especially in automotive industry. Nowadays this concept has been implemented by other sector included Small and Medium-size Enterprise. However, it has still a few number of Agro-SMEs implementing LM concept. The data from Indonesia Statistic revealed that the proportion of SME- agro based are in the total of SME in Indonesia. It insinuated that Agro-SMEs has a significant potency for national economic if their productivity increase. LM providing chance to improve productivity and efficiency in. Many research had conducted to explore LM implementation in various sector. Unfortunately, Research on LM implementation in Agro-SMEs has still a few number.  Research was conducted in 12 Agro-SMEs around Sumedang and Bandung. Selected SMEs referring to the use of horticulture and plantation commodity as a raw material. The data collected by field observation and deep interview to the owner, management-level, and employer. The data presented through description of qualitative and quantitative analysis. The result shows that the motion becomes a dominant waste in SMEs at 30%, while over production activity contributes waste at 22%, waiting aspect at 17%, inventory at 13 %, defect and transportation at 9%. Motion generates negative impact to work productivity and effectivity, for instance increase of time consume unimportant activity at work, WIP of product, cost for labor, and cost production.  In terms of Method and techniques implemented in Agro-SME, Continuous improvement (Kaizen) and 5 S outnumbered to other methods and techniques at 50%. Other method and techniques such as Teamwork and 5Why had contributed at 41.6%, TQM and Work standardization at 33.33%, and Jidoka at 16.67% as well as Kanban system, Value Stream Mapping (VSM), and SMED 0%. In terms of the reason on implementing LM, Improving the quality of product becoming a larger proportion which affecting the LM implementation at 36%. In other hand, knowledge outnumbered to others aspect. It contributes 35% as the most barrier factor on LM implementation.
