The low income of coffe farmers in Indonesia is  caused several factor, large production cost, non standart prices and high transport costs. In this paper we try to overcome this problem by establishing a geographic information system for coffe collectors, that will help farmers find an appropriate buyer with minimal shipping costs to maximized their profits. This research has been successfully implemented using Google Maps API for mapping the location and built as an Android based mobile devices application. Application on the side of the collectors can input different types of coffe prices to be purchased. While the system is on the side of farmers can search for  coffe collectors location. The test results using the system usability scale (SUS), the respondents gave a score on the farmer’s average of 74.7 and the side of the collector of 71.1 which means it has value adjective rating = excellent, grade scale = c and acceptability ranges = acceptable.
Intracellular Targeting of Heat Shock Proteins in Differentiated Human Neuronal Cells Following Proteotoxic Stress
Authors: Deane Catherine A.S. , Brown Ian R.
Published: November 2018

HSPA6 (Hsp70B’) is an inducible member of the Hsp70 (HSPA) family of heat shock proteins that is present in the human genome and not found in mouse and rat. Hence it is lacking in current animal models of neurodegenerative diseases. To advance knowledge of the little studied HSPA6, differentiated human neuronal SH-SY5Y cells were treated with the proteotoxic stress-inducing agent MG132. A robust induction of HSPA6 was apparent which localized to the periphery of MG132-induced protein aggregates in the neuronal cytoplasm. Components of the protein disaggregation/refolding machine that co-operate with Hsp70 also targeted the periphery of cytoplasmic protein aggregates, including DNAJB1 (Hsp40–1), HSPH1 (Hsp105 α), and HSPB1 (Hsp27). These data suggest that HSPA6 is involved in the response of human neuronal cells to proteotoxic stress that is a feature of neurodegenerative diseases which have been characterized as protein misfolding disorders. Constitutively expressed HSPA8 (Hsc70) also localized tothe periphery of cytoplasmic protein aggregates following the treatment of differentiated human neuronal cells with MG132. HSPA8 could provide a rapid response to proteotoxic stress in neuronal cells, circumventing the time required to upregulate inducible Hsps.

Matrix metalloproteinases (MMPs) are substantial regulators of learning and memory and might be involved in neurodegeneration. It is known that MMPs are involved in pathogenesis of Alzheimer’s disease (AD) and are particularly involved in the amyloid- β processing pathway. However, information on circulating levels of these proteins and their tissue inhibitors (TIMPs) in AD and other neurodegenerative dementia (ND) diseases such as dementia with Lewy bodies (DLB) and frontotemporal dementia (FTD) is not clear. Therefore, this study was directed toward finding out how plasma levels of MMP-2, MMP-9, TIMP-1, and TIMP-2 vary in AD, DLB, and FTD; and investigating the correlation of the levels of MMPs and their inhibitors with clinical parameters of the patients. MMP-2, MMP-9, TIMP-1, and TIMP-2 levels were measured by enzyme linked immunosorbent assay (ELISA). Plasma MMP-2 levels were significantly lower in all the patient groups than in the age-matched healthy controls (HCs) ( p < 0.05). MMP-9 levels were significantly lower in the FTD patients than in the HCs ( p < 0.05). Also, TIMP-1 levels were lower in the AD and FTD patients than in the HCs ( p < 0.05). TIMP-2 levels were similar in all the groups. These findings highlight the importance of circulating MMPs in ND and suggest that MMPs and their inhibitors might play a role in impaired amyloid- β peptide metabolism which is responsible for the genesis and progression of ND. Furthermore, measurement of MMP-2 and MMP-9 and their inhibitors may be of great importance for large scale basic research and clinical studies of ND.

New Order has given the character and style of interreligious relations up to now. But the basic framework of the religious policy of the colonial era, both the Dutch and Japanese, still must be borne in succession to carve his footsteps. This has very important implications in the management of pluralistic society, because with this paradigm also strengthened the notion that ethnic diversity, traditions, culture and beliefs of various community groups must be eliminated so that the unity imaginable can be realized. There, assimilation and harmony so basic spirit which is then translated into policies, not least the policy of interreligious harmony. Indeed, interreligious harmony has long been an obsession of the New Order regime. In fact, if you want to be tracked, the discourse about harmony emerged and strengthened with the rise and strengthening of the regime led by Suharto at that time. This article talks about the various policy New Order related to inter-religious relations in Indonesia in the past..

This article shows that, first, the educational values contained in Q.S. al-Isra '(17: 23-25), namely (1) the Aqidah education which Allah obliges His servants to press Him in worship and in worship and forbid them to associate Allah with anything or anyone. Therefore, the one who deserves the highest honors is the one who created nature and everything in it that is Allah Almighty. (2) Education of birrul walidain, after Allah commanded that not worship other than Him then Allah commanded to the Muslims so that they really pay attention to the devotional services to both mothers father and do not regard it as a trivial affair, by explaining that God is the more know what thrilled in their hearts. Second, the actualization of educational values based on Q.S. al-Isra '(17: 23-25) in the modern world, namely (1) education of the creeds in schools should teach the students in union of God that there is no god worthy to be worshiped besides Allah the Almighty God. The limited number of hours of lesson with the tarnished material causes the religious teacher to take the easiest shortcut, that is, to see religious education is no more a lesson than an education. (2) Education of birrul walidain in the modern world today is the treatment of elderly parents is really upside down. When they need more attention from the closest people, especially a child, instead they are mostly alienated from the family on the grounds to get better attention. Finally, they are deposited in nursing homes or others.

This article explains the philosophical view of progressivism about learners. Progressive philosophy sees that education is not just transferring knowledge to learners, but training their abilities and skills by providing the right stimulus. In the field of education, this philosophy was pioneered by the educational leader, John Dewey, with the main jargon of education as an instrument of social reconstruction. Progressive philosophy has the principle that learners should be educated to be human beings who can understand life in the future. For that, learners should be allowed to be free, active, creativity, and dynamic in accordance with the context of life.

Today, the human problem in social life concerning education is growing more complex; many new ideas emerge as the level of human intellectuality grows. This paper will reveal the current issue of education in Indonesia and discuss ideas from the concept of liberal education. The basic issue of education criticized by liberal education is that education today focuses more on the needs of society than the educational objectives themselves. Education as a tool to transfer science, values, and agents of social change is seen as one alternative solution in the framework of improving people's lives. The education in which values are embodied is one of the efforts offered by genuine liberal education, aimed at giving us the habits, ideas and techniques necessary to continue our own education. Humans have the ability to learn continuously throughout life so that we can prepare ourselves to study and again as long as we are alive.

Ramadan fasting is a mandatory worship for the faithful both men and women as well as past and later ones. Fasting during Ramadan that Allah prescribes in the Qur'an has a certain meaning and purpose. This paper will explain the meaning of the word 'Ramadan' and the purpose of fasting, and the meanings associated with the words ‘knowledge’ (‘ilm) described in the verses of the Quran and the Hadis of the Prophet Muhammad. This paper also aims to know about the religiosity and degrees (maqamat) that can be gained by faithful associated with worship based on knowledge. In addition, in the conduct of worship, a person needs knowledge. People who are knowledgeable and faithful will be given a higher degree by God because the knowledgeable people will obey and submit to God. Thus, it can be concluded that faith, knowledge, and worship are triangles whose sides connect and fill one another and are inseparable. Acts of kindness, noble character (amal shalih) has done by the faithful and knowledgeable can lead him to achieve the predicate of takwa as the highest degree.
PENDIDIKAN DALAM PERSPEKTIF HADIS
Authors: Siddik Hasbi
Published: November 2018

This paper will explore education in the perspective of Hadith, both the meaning, the nature, and the practice of education, as well as its urgency. In the books of Hadis (al-kutub al-tis’ah) there are many themes that talk about education. In the books it is mentioned a lot of terms tarbiyah, ta'lim, ta'dib, and other terms associated with it such as ‘ilm, al-aql, al-fikr, al-hikmah, and so on. The number of Hadis proves that the Prophet during his life did pay special attention to the issue of education. The search for an educational theme in the Hadis is a thematic study method (syarh al-mawdhui). The results of this study found that there are at least five themes in the Hadis on education: 1) the primacy of education (educating children); 2) the urgency of teaching science (in education); 3) the reward obtained for the learners; 4) fitrah (for children) to learn in education; 5) education from an early age (the obligation of parents to educate their children in worship or praying).

Interfaith relation is an important issue in the education field. Perhaps, it is because education plays a crucial role in the transfer of the science of religion and theology custody. Then religious education became a central issue in the arena of interreligious relations. Education will determine the style of interfaith relations in a plural society. Legislation on religious education thus should be criticized. The plurality of religion becomes a source of instability and disintegration seems to make the government tried to cope with any vulnerability harmony. Finally, the government issued regulations related to this issue. One of them is the Minister of Religious Affairs Decree Number 84 Year 1996 regarding Implementation Guidelines for Vulnerability Reduction Religious Harmony of Life. The operational guidelines vulnerability religious harmony is intended as a guide to the work of the officials and leaders of organizational units within the Ministry of Religious Affairs (now the Ministry of Religious Affairs) to take measures and coordinate in preventing insecurity in the field of religious harmony. Under these regulations, the causes of insecurity interreligious harmony, among others: the establishment of places of worship, evangelism, foreign aid, interfaith marriage, religious festivities, blasphemy, activity streams splinter and aspects of the non-religious influence, such as population density, the gap socio-economic, implementation of education, ideological and regional political infiltration and international scale, which entered Indonesia through religious activities. This article examines these issues in the context of Indonesia.

Published: November 2018

The author’s main concern in this research is to study the miracles of Alquran and psychology of religion. Several theories in this study are used to see the contents of the soul and the Alquran reading of the members of three majelis taklim located in Bogor Selatan District, Bogor City. This research uses qualitative method and adopts the psychology approach. The bibliographic data (primary books on the miracles of Alquran and psychology) and field (interview, questionnaire) are used to analyze the psychological miracles of the majelis taklim members. Academically, this study can complement the existing books that discuss the miracles of Alquran. In terms of the science of Alquran, this study affirms the existence of miracles in Alquran, and the psychological effects on the reader. While psychologically, this study wants to show that the holy book - in any religion - is very important to its adherents. In the end, this study would like to prove that the the members of majelis taklim who read and hear the Alquran will feel the peace and tranquility of the soul. Furthermore, reading and listening to the Alquran will not only gives peace to the soul, but can increase faith and implicate the conduct of worshipers such as prayers and infak. The results of this study show that after reading the Alquran, the members of majelis taklim feel the calm. But the implications for an increase in faith involving congregational prayer and infak very fluctuational (unstable). It can be introduced that one’s faith can indeed increase and decrease (yazdâd wa yankus).

Testing capital asset pricing model (CAPM) in Ho Chi Minh City Stock Exchange (HOSE), from traditional approach to conditional approach
Authors: Pham Minh Tien , Bui Bich Huy Hai
Published: November 2018

This study aims to test the validity of CAPM in Ho Chi Minh City Stock Exchange (HOSE). Two approaches employed in testing are (1) Fama & MacBeth’s traditional approach (1973); and (2) conditional approach developed by Pettengill et al. (1995). The research uses a time-series data set of all listed companies that are available on HOSE in each sub-period within the total sample period of 1/2007 through 6/2015. The results based on traditional approach show that CAPM does not offer a good explanation of risk-return relationship in HOSE. However, when considering market conditions (up/down) proposed by conditional approach, the findings are consistent with the CAPM prediction.
Origin of NOx emission from ships inside major bays in Japan
Authors: AZETSU Akihiko
Published: November 2018

The amount of NOx emission from ships inside the major bays in Japan, i.e., Tokyo Bay, Osaka Bay and Ise Bay, are analyzed and the strategies in the reduction of NOx emission are discussed. Normally each ship has three sources of NOx emission, i.e., main engine, auxiliary engine and auxiliary boiler. Since wide range of ships are in operation in these bays, each of the ships are categorized in 4 ranks by the size of each ships. The amounts of NOx emission from each source and each rank of ships are estimated separately and compared with each other to understand the origin of NOx emission inside these bays. From the systematic calculations, it was explored that more than half of the amount of NOx was emitted from the auxiliary engines during the anchorage period. Especially the influence of the NOx emission from auxiliary engines of larger sized ships of rank 4, the largest category, is the largest. This should be mainly due to the longer anchorage and cargo work time necessary for handling the larger amount of cargo of larger sized ships. On the other hand the NOx emission from main engines is mainly emitted from the small sized ships of rank 1. Same tendencies are obtained through the NOx emission calculations of three major bays in Japan. From these results, it is suggested that the usage of land electricity in larger sized ships is effective in the reduction of NOx emission in major bays.

The possibility of using the gradientless n-parametric minimization of Powell'64 in the tasks of monitoring the workflow of ship diesel engines is considered. Monitoring the workflow of ship diesel engines includes the problem of cyclical analysis of indicator diagrams in the working cylinders. The problem of data synchronization should be solved - the transfer of pressure charts from the time function to an angle of crankshaft rotation function. It is shown that the hardware detection of the crankshaft rotation phases applying pick-up sensors configured in statics will have errors when the engine is under load. The synchronization task should be solved with the help of an algorithm by analyzing the indicator diagram in real time. Examples of the search for a global minimum of the Rosenbrock test function are given. Applying the Powell'64 method, least square method functionals are minimized in problems of synchronization and modeling of compression-expansion curves in the working cylinder. Cases of data synchronization calculation for low-speed two-stroke and mid-envelope four-stroke marine diesel engines are shown. Taking into account the assumptions made in practice, it was shown that at the point of maximum pressure growth rate on the compression curve, the cylinder volume above the piston can be calculated applying the known geometric dimensions of the cylinder and the P and dP/dφ values obtained from the indicator diagram. The next step is to calculate the first approximation of the position of the top dead center of the piston, and the application of the digital filters is necessary. Finally, the synchronization problem is solved on the basis of the equation dP/dφ = 0, compiled for the section from the start of compression to the start of combustion in the cylinder. The selection of boundary conditions for modeling is shown. The advantage of applying the Powell'64 method is its high efficiency for quadratic functionals. Unlike gradient methods, the Powell'64 method does not require the calculation of derivatives and is universal to minimize complex nonlinear functionals of a general form. The original author's algorithm for data synchronization by analyzing indicator diagrams, which applies the Powell'64 method, is used in the latest versions of the D4.0HT marine diesel engine monitoring systems

Solving the problem of ocean's airspace polluting with harmful emissions of ship-generated diesel engines by exhaust gases is associated with the creation of highly effective technologies for the neutralization of nitrogen oxides NOx from the diesel plant that apply both to vessels in service, designed and built. The air entering the engine is a working fluid that carries out a certain thermodynamic cycle, resulting in a change in its chemical composition, and the exhaust gas mixture contains many components. Emissions of harmful substances during the combustion of marine fuels are limited in accordance with international programs for the protection of the atmosphere and requirements of the International Maritime Organization IMO. Requirements apply all groups of harmful emissions of marine engines. The most stringent of them concern nitrogen oxides NOx and sulfur oxides SOx. To reduce harmful emissions from the exhaust gases into the environment, scientists and world leaders in engine construction, such as MAN Energy Solutions and Wärtsilä, apply and offer a variety of techniques to reduce the number of harmful substances in the exhaust gases. One of the most promising is the exhaust gas recirculation system (EGRS) of the ship diesel engine. Its advantage over other methods is the insignificant impact on the operation of the engine. During the exhaust gas recycling a temperature of the flame in the combustion chamber decreases, which leads to the reduction of NOx number. This is a consequence of the high rates of carbon dioxide and water vapor. Since the combustion rate is reduced, the exhaust temperature and the thermal load on the engine part are increased. The dilution of the inflow air with waste gas reduces the oxygen content in the supercharged air from 21 to 13%. The possibilities of the technology of the system of recirculation of exhaust gases of a marine engine are limited by the value of the ratio of O2/CO2 in the intake air, due to which the amount of combustion products at the inlet is limited to no more than 30%

Prospective methods of aerosol medium separation with the help of gradient intensification of transfer processes in boundary layers of multifunctional surfaces are also investigated. Multifunctional surfaces include surfaces with a coefficient of compactness more than 2000 m2/m3, characterized by improved heat exchange and separating properties. A characteristic feature of the developed separating profiles is the combination of a waveform part with flat input and output elements. In the assembly, the separating profiles form the curved channels with a number of successive confuser and diffuser elements. In diffusor elements, there are separating zones with the gas reverse flow. The liquid film resulting from the droplets deposition, falling into these zones, is influenced by the vortices effect that counteracts the film motion in the direction of the main flow and facilitates its flow under the action of gravity. The investigations of gas dynamics and deposition coefficients of the separation profile were performed. The coefficient of droplets deposition for flow rates of 5, 10, 15, 20 m/s in separating profiles with a radius of 5, 10, 15, 20, 25 mm was calculated. It was determined that vortex zones provide full removal of captured water from the smooth surface profile up to the airspeed of 5 m/s. Excess of this speed leads to the removal of part of the water from the vortex zones. Drainage elements are provided for preventing secondary flooding of the flow in flat sections of the separation profile. Design solutions and a generalized scheme of the ship system of air cleaning of condensed moisture for the air flow from 20 to 2000 m3/h were developed. The introduction of filters based on gradient technologies will increase the reliability, the life of the marine power equipment and its elements. This will contribute to the creation of high-efficiency energy-saving technologies and efficient design solutions for a wide range of gradient marine power plant separators.

Technology, equipment, and results of stand tests of plane wheel hubs and flanges strengthened by surface plastic deformation are described. The new method suggested by the authors is called vibrational-centrifugal strengthening treatment. It belongs to the method group of dynamic strengthening of revolutional shape parts. It is based on impact interaction of the part processed with a massive tool which is rolled over the strengthened surface of the part when under vibration. Moreover, the impact contact between the part and the tool occurs through a small number of deformable bodies. This provides formation of compressive residual stress in the contact places in the part material. For magnesium wheel hubs (alloy ML-12) residual compressive stress is within 110 MPa, for aluminium ones (alloy AK6) it is within 250 MPa. The degree of strengthening of outer zone material for magnesium wheel hubs is 45...59 % with surface micro-hardness increasing up to 1150 N/m2 and the thickness of the strengthened layer being   0.9...1.0 mm. When strengthening aluminium wheel hubs and flanges, the thickness of the strengthened layer is to be 0.6...0.9 mm with a degree of cold work being 25...30 %. Fatigue studies of a party of KT-141 type wheel hubs strengthened by the method (magnesium alloy MT-12) demonstrated their service life increasing up to 1000 take-offs and landings at the safety coefficient of n = 3.5. The lifetime of this type of wheel hubs strengthened by roller burnishing did not exceed 750 take-offs and landings; for unstrengthened ones, it made 500 take-offs and landings at lower values of the safety coefficient. Strengthening the wheel hub web KT-150K (aluminium alloy AK6) increases their lifetime by 28...30 % on average. Apart from plane wheel hubs and flanges, the method of vibrational-centrifugal strengthening treatment can be applied for increasing the lifespan of various parts of chassis components of circular section, for strengthening nonferrous metal webs of car wheels, radius blends and steel shaft journals etc.

The subject of study is the integration of linear and nonlinear methods for the solution of image restoration applications. The aim is the development of signal filtering algorithm and image model building. The tasks are to develop a criterion for impulse form signals; to develop an effective solving algorithm. The applied methods are optimal filtering method, mathematical models of optimization, the method of independent component analysis. The results are the following: the problem of choosing the optimal structure of the algorithm is formulated, complexing of linear and nonlinear methods for solving the inverse problem is considered, the criterion of optimization for signals of the impulse form, the optimization criterion for pulse signals is selected. The criterion is applied to select the filter kernel. The results of control restorations for distorted images are presented. The recovery error is estimated as a function of the signal-to-noise ratio. Conclusions. The following new results are obtained: the method of optimal filtering based on a cumulant of the second order for pulsed signals has been improved by introducing an appropriate criterion. The obtained estimate is used to form a linear model of observation. The solution of the obtained system of linear equations (SLE) is found in the framework of the analysis of independent components (ICA), based on the fourth-order cumulant. A model of the distorted image is constructed and the results of the reconstruction are given. It is shown that for impulse waveforms, it is possible to apply the stopping criterion of the iterative process on the basis of higher-order derivatives. The quality of filtration in the norm of L2 is estimated depending on the signal-to-noise ratio. The simulation results show that the recovery error decreases at ratios more than 10. The results of the studies performed in this paper can be used in the development and modernization of various radio engineering systems of aircraft

Matrične faktorizacije
Authors: Radošević Medvidović Ines , Pedić Kristina
Published: November 2018

Matrice se dijele u različite klase, ovisno o formi i određenim svojstvima. Matrične faktorizacije ovise o svojstvima određene klase matrica pa su faktorizacije matrica od velikog značaja u teoriji matrica, pri analizi numeričkih algoritama i uopće u numeričkoj linearnoj algebri. Faktorizacija matrice A je prikaz matrice A kao produkta "jednostavnijih" matrica, što omogućuje jednostavnije rješavanje nekog problema. U teoriji matrica značajne su faktorizacije onih matrica kod kojih je moguća transformacija sličnost, kod što su Schurova dekompozicija, spektralna dekompozicija, singularna dekompozicija. Nadalje, osnovni alat za rješavanje sustava linearnih jednadžbi, kao jednog od osnovnih problema numeričke linearne algebre, je LU faktorizacija. Također, bitno je spomenuti i QR faktorizaciju i njeno računanje preko rotacija i reflektora.

U radu je provedeno eksperimentalno određivanje linijskih i lokalnih gubitaka, odnosno koeficijenata linijskih i lokalnih gubitaka na nekoliko karakterističnih fazonskih komada unutar cijevnog sustava pod tlakom. U svrhu izračuna navedenih koeficijenata, dane su mjerodavne formulacije za njihovo određivanje. U sklopu rada na fizikalnom modelu GUNT HM 150 u sklopu Praktikuma hidrotehničkog laboratorija Građevinskog fakulteta Sveučilišta u Rijeci, provedena su tri osnovna eksperimentalna mjerenja: proračun određivanja lokalnih gubitaka na cijevnom koljenu (pod kutom od 45° i 90°), hidraulička analiza uslijed promjene poprečnog presjeka cijevi (postepeno suženje i proširenje cijevi) te hidraulička analiza uslijed grananja cijevne dionice (račvasti dio cijevnog sustava). Na kraju rada dani su zaključci koji proizlaze iz provedenih eksperimentalnih pokusa, kao i smjernice za buduća dodatna ispitivanja lokalnih i linijskih gubitaka na danom fizikalnom modelu.

U radu su prikazani rezultati terenskog dinamičkog ispitivanja pješačkog nathodnika Malonji korištenjem operacionalne modalne analize za određivanje modalnih parametara konstrukcije. Izmjereni modalni parametri uspoređeni su s modalnim parametrima izračunatim na numeričkom modelu nathodnika. Pokazano je da ovom vrstom dinamičkog ispitivanja i obrade podataka moguće dobiti dobro poklapanje između izmjerenih i izračunatih vlastitih frekvencija dok bi za točnije određivanje vlastitih oblika na temelju izmjerenih ubrzanja trebalo uvesti poboljšanja geometrijskog modela u ModalVIEWu boljim rasporedom ili povećanjem broja mjerenih stupnjeva slobode te korištenjem akcelerometara veće osjetljivosti.
