Abstract
Brazil nut effect is a phenomenon in which large-size particle lift up when vibrated vertically on granular system. This phenomenon has been studied both through experiments and computational simulations. One parameter that can be extracted from this phenomenon is the final height of the large-size particle. However, due to the large number of input parameters that affect the final results, the way to predict is still the subject of study. In this study, we used artificial neural network (ANN) as a method to predict the final results of experiments through molecular dynamic simulations with different input parameters. The different input parameters were created by generating random numbers of the appropriate range. After the simulation was carried out and the final result was obtained, the input and final parameter data were used as a database for training ANN. To get optimal results, a comparison is made of various ANN model architectures.

Abstract
Increasing demand and use of energy and declining energy source make today’s society have to do energy efficiency. The main focus of this energy efficiency research is AC (Air Conditioner) system because it contributes the most of total power consumption of building. The problems hindering the energy efficiency process on AC system is that the sensor in the AC system doesn’t represent the room’s thermal condition, parameters relevant to the thermal condition are not considered, and the control used only uses temperature optimization without considering energy efficiency. The solution proposed is designing a system that can overcome the problems with Internet of Things (IoT) technology. Other than physics modelling on thermal characteristics using thermodynamics and heat transfer concepts, Artificial Neural Network is also used to manage control part of the system. This research is conducted using experiment method on AC system and room of IoT Laboratory, Department of Physics, Institut Teknologi Bandung. The study on the effects of Duty Cycle (DC) and difference between outdoor and indoor temperature on thermal characteristics value, time needed to obtain thermal characteristics, the effects of DC and outdoor temperature on indoor temperature, the effects of room occupancy on thermal characteristics value, and control result have been conducted. The control has been tested: the average temperature is 21.98$^0$C on outdoor temperature value about 27$^0$C, the temperature range is 21.98$^0$C $pm$ 1.7$^0$C, and the saving obtained is 60%.

Abstract
At present, Indonesia has a very large shale hydrocarbon potential, where the Central Sumatra Basin is the biggest potential in Indonesia, especially from the Brown Shale Formation of the Pematang Group. However, the development of shale hydrocarbon in Indonesia is still little studied and poorly understood. Thus, research related to non-conventional hydrocarbon resources is very important in order to improve sustainable national energy security. But further research must be carried out using analog outcrop data, because there is no data core from the Brown Shale Formation of the Pematang Group. Fortunately, there are currently very good analog outcrop at the PT. Karbindo in Kiliran Jao, West Sumatra. In this paper the sweetspot fracable window is determined by using a geomechanical analysis approach from core / analog outcrop samples, so that the prospect formation interval model with a high fraction can be created, which correlates with fracture resistance, and can be applied to determine the location and planning interval for hydraulic fracking. From the sweetspot fracable window of shale hydrocarbon, it is expected to increase success in producing shale hydrocarbons which have very low permeability by determining the exact location and hydraulic fracking interval, so that natural cracks can be opened, and the fracture is connected to maximize hydrocarbon flow.

Abstract
The keynote address on Malaysia Politics and Government in the Post-2018 General Election-Change and Democratisation? focuses, first, on the issue of linking political change to democratisation. In the process, political change that Malaysia went through after the 2018 General Elections were being seen through the lense of democratisation. Many analyses proceeded from that basis, but some are now beginning to rethink whether the change that occurred in 2018 really has led to “more” democratisation. The second focus of the paper is arguing that change and democratisation may still happened but within the framework of Malaysia political system, and that the processes and events cannot really be judged based on indexes borrowed from other political system.

Abstract
Indonesia is a country rich in ethnic, cultural and religious diversity. There are approximately 746 different languages in Indonesia. Six different religions. from Sabang to Merauke Indonesia has different ethnicities and cultures in each region. With the weakening of culture at this time local wisdom was lost over the times. Traditional village islocal wisdom that is able to preserve customs until now. Like some traditional villages located on Java The West, every traditional village has rules, art, and customs for each of the beliefs in the village adat. Kampung Naga is a traditional village that is still sustainable and still has an ancestral heritage of 10.5 hectares with 113 buildings, and 108 family heads. Researchers and community services who will carry out activities in Kampung Naga will get a local guide to help get information, but for tourists just visiting to enjoy the beauty of the dragon village does not get a local guide unless asking foraccompany. Naga village community considers the number of tourists who come, namely gathering and gathering introduction of friendship. But tourists also have to follow the rules there. Making visual-based information media to introduce Kampung Naga customs to tourists do not use local guides to find out about the history of customs in Kampung Naga and contribute to preserve Kampung Naga customs.

Abstract
The fashion industry is one of the largest contributors to the economy in Indonesia. However, this industry is the producers of both pre-production and post-production waste in large quantities causing environmental pollution. To meet the needs of consumers for fashion products, this industry actively design or renewing the design of apparel, resulting fabric waste from production in significant quantities during the process. Currently, there are varying viewpoints from practitioners and academics who argue that in order to reduce waste, the effort will be optimized when done during the pattern making and cutting process. Since the year 2008, the concept of zero waste fashion design or better known by the acronym ZWFD has been widely studied and practiced by students, academics, and practitioners in the field of fashion that has interest in the issues of waste pre-production and its influence on the environment. ZWFD itself refers to the steps to produce apparel with the minimum waste from fabrics during the pattern making and cutting process. This research aims to examine how the concept of ZWFD can be implemented in the course of design and apparel production.

Abstract
The era of development made traditional culture erased by foreign cultures, therefore as a precautionary measure, the Bandung City Government issued a Regional Regulation requiring Bandung residents to preserve Sundanese Culture written in Perda No. 5 of 2012 and Perda No. 9 of 2012 article 10 paragraph 1b. In the context of tourism, the city government of Bandung also encourages hotel entrepreneurs to participate in the preservation of Sundanese Culture, because up to now there are still around 10 percent of entrepreneurs who run the Perda. The news review on galamedianews (April 2, 2018) revealed that only 6 out of 400 hotels in Bandung City display traditional arts in an effort to preserve Sundanese Culture. One of the superior traditional arts of Kota Bandung is batik art. Grand Preanger is a 5 star hotel located at 0 (zero) kilometers of Bandung City and has become a historical landmark of Bandung and is one of the most famous places in the Art Deco era. This hotel is the result of a shop renovation by W.H.C. Van Deeterkom in 1897, became a Preanger Hotel which changed its name in 1920 to the Grand Preanger hotel which was designed with a blend of Art Deco style and a touch of Sundanese culture, one of which was the application of Sundanese batik in the interior of the hotel. The purpose of this research is to find out and find the application of the implementation of Sundanese batik in the interior design of the Grand Preanger hotel, so that this study will produce a design guide for young interior designers and the general public in applying Sundanese batik in interior design.

Abstract
Rotenone, a natural pesticide inhibit mitochondrial complex I enzyme that caused the increase of reactive oxygen species (ROS), reduced ATP production and stimulate apoptosis. This condition will affect the proliferation and development. IGF-1 (Insulin-Like Growth Factor-1) is a protein that responsible for growth and development in prenatal and postnatal of somatic cells. IRS (insulin receptor substrate) responsible for signal transduction of IGF-1 for cell differentiation, proliferation, and anti-apoptosis. Gotu kola (Centella asiatica) had long been used as herbal medicine. Its contains triterpenes as antioxidant and anti-inflammatory properties, macro and micronutrients as well. This study observed the effect of Centella asiatica (CA) extract to the expression of IGF-1, IRS and the linear growth of rotenone-induced zebrafish larvae. The zebrafish embryos were divided into 5 groups: control, Rotenone 12 ppb, Rotenone and CA extract concentration 2.5, 5 and 10 μg/ml respectively exposed from 2-hours post fertilization (hpf) until 3-days post fertilization (dpf). The expression of IGF-1 and IRS were conducted at 9 dpf by immunohistochemistry whole-mount and quantify the expressions by Image J software. The body length measured at 3, 6 and 9 dpf using Image Raster from optilab v2.2.1. The data analyzed using one way anova from SPSS v.18. The results showed that rotenone significantly decreased the IGF-1 and IRS expression (p<0.05). The administration of CA extract could be increased the expression of IGF-1 and IRS in rotenone-induced zebrafish larvae. The measurement of body length showed that rotenone reduced the body leng of larvae after 6 dpf, and 5 µg/mL of CA extract significantly increased the body length at 6 and 9 dpf. It can be concluded that CA extract increased the body length of zebrafish larvae through the increasing of IGF-1 and IRS signaling.

Abstract
Stunting is the failure of linear growth during the first two years life. Rotenon is one of the pesticide causes stunting. Rotenon as the Endocrine Disrupting Chemicals (EDCs) and 1 complex mitocondria inhibitor, causes the decrease of ATP, increase the ROS and caused oxidative stress. Centella asiatica is a plant contains high antioxidant and cause the balance oxidant in cell so oxidative stress can be decreased. The purpose of this study is to know the pegagan etanol effect toward the rotenon induced zebrafish larvae stunting model toward expression increasing of Glucose Transporter 4 (GLUT 4) and Osteocalcin. The research proved rotenon [12,5 ppb] can cause stunting of zebrafish larvae which included age 6 and stay until 9 dpf. The expression of GLUT 4 and Osteocalcin in zebrafish larvae which rotenon-induced decrease significantly compared with control group. The expression of GLUT 4 increase significantly by adding pegagan concentration 5μg/ml, while the expression of osteocalcin increase significantly by adding pegagan concentration 2,5μg/ml and 5μg/ml. Rotenon [12,5 ppb] can induce stunting of zebrafish larvae (Danio rerio). Addition of pegagan etanol extract can give effect for stunting zebrafish larvae through increased expression of GLUT 4 and Osteocalcin. This is indicated by an increased in body length.

Abstract
Bacillus subtilis is one of the microbes that is known very potential to degrade heavy oil because it can produce biosurfactants. The presence of biosurfactant makes Bacillus subtilis able to degrade the chains of carbon atoms in heavy oils that are very long and complex. The ability of Bacillus subtilis to produce biosurfactants is caused by the sfp gene which is required to produce Sfp 4-phosphopantetheinyl transferase protein. To know the characteristics and pathway of the sfp gene in producing biosurfactants, molecular analysis was carried out by using bioinformatics. The analysis carried out includes an analysis of the primary structure, secondary structure, and tertiary structure of the protein produced. Further analysis using EcoCyc was conducted to determine the Sfp 4-phosphopantetheinyl transferase protein metabolism pathway. Based on the results of the analysis carried out related to the sfp gene, it has a conserved protein motif associated with a fairly low similarity with some EntD proteins from Escherichia coli. Based on the EcoCyc analysis known that AccS as a group of genes that produce 4-phosphopantetheinyl transferase Sfp and Associated EntD proteins play an important role in maintaining membrane cell function. The expression of the sfp gene is controlled by the Crp and Fur transcription activator. Excessive expression of the SFP gene will help the secretion of secondary metabolites capable of breaking complex carbon atom chains in the heavy oil.

Abstract
The consumption of beef in Indonesia continues to increase every year, but national beef production is only able to meet 65% of domestic demand. Therefore, a new innovation is needed to increase the productivity of cattle, one of them by twinning births in cattle. The identification begins with taking blood samples of cattle. Then isolation of bovine blood DNA, amplification of sequence ovulation rate gene, horizontal electrophoresis, and then sequencing. The sequencing results were then analyzed using bioinformatics software to see the sequence variation and thus found predictions of established polypeptides which might play a role in the rate of ovulation of Limousin cattle. Based on the results of the analysis, there was a sequence variation and the prediction of the polypeptide formed was Cytokine (TNF Tumor Necrosis Factor). This shows that the variations that occur cannot change the polypeptide formed, because the polypeptide formed from the three samples is a class of cytokines that have a function for ovulation in mammals. Thus it can be concluded that the variation of gene sequences does not change gene function can be said to be gene conserve and conservation and breeding to increase cow productivity.

Abstract
The Madura cattle is one of Indonesian that have the advantages. One of the genes regulating genital formation in males of Madura cattle is the Sex-determining Region Y gene (SRY), this gene is dominant in regulating sex determination and fertile markers in male cattle. This study aims to determine the genetic variation of the SRY gene DNA sequences in local male Madurese cattle and analyze the function of these genes. The research method used for total blood DNA isolation was the phenol chloroform method. The SRY gene amplification samples were DNA sequenced and analyzed bioinformatics. The results of the SRY PCR gene electrophoregram show bands with a length of + 600pb. Five different regions on Madura Island were used as sampling locations, namely Lombang, Pajudan, Pasean, Kanang and Kanwa. The occurrence of transversion mutations in the 4th base sequence with the monomorphic pattern and prediction of the polypeptide showed the same polypeptide results from the two samples, namely AP-1 Complex. This protein has an important role as a transcription factor in the normal development of the testis. The sequence variation obtained is able to bring about the nature of heterozygosity and increase the value of genetic diversity.

Abstract
Journaling is believed to have many benefits, yet it is not widely used in EFL classrooms. This paper aims to explore the students- voices regarding the implementation of regular journaling in their writing class. The data were obtained from their written reflection after they wrote weekly journals for one semester. The qualitative analysis of the students- reflection revealed that the students- perceived journaling as something worth doing because it offers some advantages, both psychologically and academically. Psychologically, they think journaling is a good means of epressing their feelings and ideas especially when they do not have enough courage and confidence to speak up in the class. Journaling can make them feel ‘heard- without feeling ashamed and fearing of being evaluated. Academically, they believe that journaling can develop their writing habit and improve their writing skills. They further recommend that journaling should be done more frequently.

Abstract
Campus has a strategic role in preparing the community to face possible disasters. To achieve this role, a commitment is needed to make the campus a disaster mitigation perspective, so that it becomes a medium for disaster mitigation education. The purpose of this study is to review the extent of campus commitment, especially the University of Education Indonesia (UPI) in making its campus disaster mitigation-minded. The research method used is a survey method for campus residents. The results of the study indicate that UPI has made a number of efforts to make its campus insight into disaster mitigation, but there is still a lot that needs to be improved. These efforts are generally still limited to the provision of physical facilities, not yet on the aspect of empowering campus residents. A number of weaknesses were identified in the form of the absence of a Disaster Risk Assessment Document, Campus Action Plan and Early Warning System, there were no massive socialization of disaster mitigation, and the absence of resource mobilization efforts.

Abstract
Determining instructions of higher order thinking skills in curriculum 2013 is still challenging and new for most English teachers in Indonesian context. Therefore, this current study emphasizes on investigating teachers- understanding in constructing higher order thinking-based assessments and teachers- difficulties in designing the assessments. A case study was applied with two research instruments, namely document analysis in the form of teacher-made assessments and interview with the teachers. The participants of this study were two English teachers from two different junior high schools- one public school and one private schools as the users of Curriculum 2013. The findings reveal that a misconception about the concept of higher order thinking skills assessments among teachers is still found because the teachers dominantly focused on the degree of difficulty of the questions instead of cognitive complexity in designing higher order thinking assessments. Consequently, the test items of the teacher-made assessments may only promote the students- analyzing and evaluating skills, so that the creating skill as the highest level of HOTS seemed not to be identified in the teachers- test. In addition, from the results of interview with the teachers, they claimed that most of the questions were constructed in the form of multiple choices to measure the students- HOTS and they were not confident to modify the multiple choices to be essays and open-ended questions forms as characters of HOTS assessment. It happened because the teachers believed that creating skill is related to a product of written texts. Overall, it is concluded that the teachers- understanding about HOTS-based assessment was likely low and needs to be improved through exposures and enrichment by attending trainings and workshops about HOTS-based assessment.

Abstract
The educative communication is essential to be noted since it is one of the components of teaching and learning activities in relation to the quality of educative communication constructed between the teacher and the student. The failure of achieving the learning objectives can be caused by the infringement of the conversation principles, not only in terms of cooperation principle but also politeness principle in the classroom interaction. Therefore, the realization of the conversation principles in the classroom interaction needs to be investigated to discover the interaction-s strength in learning so that the competences can be achieved by the students effectively and efficiently. Through the recording of the teacher and students- speech in Indonesian classroom interaction of class X, it was found that there were adherence and infringement to the cooperation principle and politeness principle. The adherence to the cooperation principle occurred in maxim of quantity, maxim of quality, maxim of relevance, and maxim of manner. The infringement of cooperation principle occurred in maxim of relevance and maxim of manner. The adherence of politeness principle occurred in maxim of agreement, maxim of wisdom, maxim of sympathy, and maxim of appreciation. The infringement of politeness principle occurred in maxim of wisdom, maxim of appreciation, maxim of modesty, and maxim of agreement. Through the realization of the conversation principles in the classroom interaction, it can be concluded that the quality of educative communication affects the achievement of the learning objectives.

Abstract
Local wisdom is an element that is very important for human life which contains values, norms, and customs that are valid and have been around for a long time. The existence of local wisdom is a necessity because it was born and developed Along with the birth of life and culture and is used as one of the main points in the development of Education. However, in this technological era local wisdom is at a point where it continues to exist and is able to face technological challenges or turn into a global culture. Through research with qualitative design and using participatory observation strategies conducted in the Kampung Dukuh of West Java, Indonesia for 3 years, it was concluded that the existence of local wisdom could be lost due to massive use of technology in all fields, especially in the social aspects where human interaction was guided by technology. However, on the other hand this research has proven that technology combined with local wisdom that aims to maintain the existence of both succeeded in increasing peoples understanding of the values of local wisdom and the importance of this as the core of Education that emphasizes values and norms. The implications of these brilliant results are expected to be able to motivate the next generation to be able to become good citizens of the world by prioritizing local wisdom values as one of the cores of Education.

Abstract
This study tries to determine the condition and effect of participative leadership style and teamwork on the performance of insurance agents.. The population of this study is insurance agents of PT Axa Financial Indonesia Malang, amounting to 148 agents. Meanwhile, sampling in this study taken by using simple random sampling method with 108 agents return the questioner. Data were analized by using multiple regression analysis. The results showed that condition insurance agent-s performnce and the participative leadership style were in very good condition, while teamwork condition was good. Moreover, participative leadership style and teamwork have significant positive effect on the performance of insurance agents. However, the competition between agent still exist and leaders are less listen to their teammates. Therefore, it would be better for the leader to direct the “competition” situation between agents to the positive way or positive competition and more listen carefully to their team members and respect their voice in order to increase their performance
