Abstract
A new ocean tide model for the Indonesian Sea has been estimated by assimilating TOPEX+JASON (27 years), ENVISAT (8 years), GFO-1 (8 years), and 100 coastal gauge stations (2-5 years) data into a barotropic hydrodynamic model. The new model consists of more than 25 tidal constituents, with a spatial resolution of about 2.5-. The respond method was employed to estimate the amplitudes and phases of about 280 tidal constituents. Only constituents whose amplitudes are larger than 1 cm are added to construct the new model. According to comparisons with another 40 coastal tide gauge stations and collinear residual reduction test, the new model provides a better performance compared to global ocean models, in particular around shallow waters and coastal areas. This advantage is due to the following reasons: (i) fine-scale along-track tidal analysis of multi-mission altimetry and coastal tide gauge data and (ii) optimal estimates of friction velocity and the decorrelation length in the hydodynamical equations.

Abstract
Many areas of Indonesia are belong to coastal low land area. Geometrically the topography is just only several meter above the sea level and even in some places they are already below the sea level. In the recent few decades the sea is rising (e.g. sea level rise) and the land is sinking (e.g. land subsidence). Both combination of phenomenon has made the coastal low land area prone to sea water inundation or sunny flood (“rob” in Javanese). Clear examples have been found around northern coast of Java and east coast of Sumatra. In certain places in the two islands, the permanent inundation is existed obviously. They are hazard turn to disaster. The losses is huge especially to the material. Millions of Dollar has gone. Creating hazard map of these cases in Indonesia is an urgent need to support mitigation and adaptation against those issues. Nevertheless there are several data and information requirement like Digital Terrain Model (DEM), magnitude of sea level rise and subsidence, etc. which arenot available completely or properly. This is a challenge. This paper will be highlight about those urgent need and the challenge.

Abstract
Producing better wind wave numerical forecasting products by utilizing real time ocean wave observation data is still a challenge for marine meteorologist. The altimeter sensors installed on the Sentinel SAR/1B and JASON-3 satellites have the ability to do spectral measurement to determine the wave energy with the growth rate of wind waves frequency that will be formed. This study examines the verification and evaluation of wind waves from WaveWatch-3 model (Ina-Waves Products) by comparing wave spectral of Sentinel SAR/1B and JASON-3 satellites during Ina-PRIMA 2018 research in June with the wind waves footprint-directional wave-spectral technique. The output of WaveWatch-3 model based on a comparison of numerical Gaussian swell spectrum shows that the wave growth pattern is dominantly in the frequency of 0.11 - 0.34 Hz with an accuracy of swell formation of 83% from Sentinel SAR/1B satellite observations. The results of Ina-Waves model from the WaveWatch-3 model output with deep water waves along the shipping tracks and 5 buoy points show that the accuracy of significant wave height at 85% and the error rate is 0.45 meters from the Sentinel SAR/1B. Correction of the comparison of Sentinel SAR/1B and JASON-3 satellites resulted in a correction of Ina-Waves products of 0.40 meters. This result becomes a correction of input data towards the development of numerical surface waves models in Indonesian waters.

Abstract
Sea level variability is one of fundamental parameters for scientific development such as modeling the Earths climate. In addition, this parameter also plays crucial rules in mitigating socio-economic hazards due to sea level changes, especially in coastal areas. Mitigating the sea level hazards in an archipelagic country like Indonesia becomes more essential, since the country is geographically constructed by various bathymetric depths with different type of seas. One of attempts to study the sea level variability is to take benefit from satellite altimetry data. The TOPEX+JASON altimetry missions have observed sea level during more than 25 years, and hence the rate of sea level variability can thoroughly be studied. In this research, regional-scale variations in sea level over the Indonesian sea will be examined.

Abstract
Sea level spatio temporal variability in Indonesian waters is an important oceanographic aspect to be investigated. This is related to the use of satellite altimetry data in physical geodesy studies in the region. Due to its location at the equatorial zone and as an archipelagic region, Indonesian waters should experience complex behavior and pattern in term of sea level. Identification and analysis of those phenomena require precise sea level observation over a long period of observation. Topex, Jason 1, Jason 2, and Jason 3 satellite altimetry missions have been observing sea level for more than two decades. In this research, the use of these altimetry data from 1992 to 2019 in identifying and analyzing the long term sea level variability in Indonesian waters will be investigated.

Abstract
The purpose of this study is to analyze the sources of development funding originating from Corporate Social Responsibility (CSR) funds from both private companies and State-Owned Enterprises (SOEs) in Bandung, West Java, Indonesia. CSR funds are funds that are set aside from profits earned by the company. Private companies carry out CSR programs due to demands from the Limited Liability Company Law whereas SOE companies carry out CSR programs because there are instructions from SOE ministries. The research method used in this study uses a qualitative approach to the type of exploratory research. Primary data sources were obtained from in-depth interviews with several informants. While secondary data obtained through tracking research results and documents relating to the use of CSR funds in the city of Bandung. The results showed that the implementation of CSR in the city of Bandung was running, but the implementation was still done partially. The company implements CSR programs in accordance with each companys policies. They run CSR programs only limited to spend the budget without analyzing whether the program is useful or not. The local government has not been involved in CSR activities carried out by each company. Local governments can actually optimize CSR funds by collaborating both in development planning and financing. However, the huge potential source of funding from CSR funds cannot yet become an alternative source of regional development funding.

Abstract
Ocean currents have a big role in the marine world. Conventional techniques of measuring ocean currents have spatial and time limitations. High Frequency Radar technology can overcome these obstacles as an alternative to solving solutions effectively and efficiently. The hydrodynamic model is used to predict sea surface currents, such as in Indonesia, known as Ina flows from BMKG and Ina OFS from Pusriskel. The aim of this study is to find out the accuracy of the Ina flows and Ina OFS hydrodynamic models in predicting sea surface currents against high frequency radar observations in Labuan Bajo Waters. The data used are output from Ina flows, Ina OFS and HF Radar in Labuan Bajo in February 2019. The method used to determine accuracy is by correlation coefficient, Root Mean Square Error, and eyeball method for spatial correlation. In general, the results of these tests indicate that Ina-flows has a higher value of accuracy and correlation in two points of the waters of Labuan Bajo with a value of around 0.5 to 0.6, while the error of sea surface currents direction is around 30 degrees to 60 degrees.

Abstract
One of the abilities of the 21st century that students must have is creativity, but this ability is not too meaningful if it is not accompanied by a good spiritual attitude (in accordance with the 2013 curriculum in Indonesia), as well as always being a concern for public schools research is rarely focused on religious-based schools (madrasah) even though the potential is no less great than public schools. So from that the aim of this study is to analyze the creativity and spiritual attitudes of students who appear in STEM-based reproductive system learning through performance assessment. The research methodology is descriptive, sample used was one of 11th grade classes in “Science” specialization in MAN 2 Tasikmalaya with 36 students as participants. Creativity here is seen from a creative person (Person), the creative process (Process), the pressure that arises (Press), and the product it produces (Product). The results of the research show that the students of madrasah (in this case MAN 2 Tasikmalaya) have different levels of creativity, both compared in terms of "person", "process", "press", and "product" no one has a level of creativity same. On average students have "emerging" category creativity. Creativity is also not directly related to students personal spiritual attitudes, however, some students who have very good spiritual attitudes tend to have creativity that is categorized as "expressing".

Abstract
This study aims to determine the visual meaning of KangPisMan mascot. KangPisMan mascot was raised to support the KangPisMan movement as a Bandung City Government program to reduce, reuse and recycle trash. The visual meaning of KangPisMan mascot can be known using Roland Barthess semiotic method. This method describes the denotation, connotation and myth aspects found in the visual elements of KangPisMan mascot. The results of the study show denotative meaning that appears in the form of visual objects, colors, clothing, expressions and gestures of KangPisMan mascot. The connotative meaning of the KangPisman mascot is to convey the value of delay that arises from the visual sign relation. This delay value is combined with the symbolic concept of the KangPisman movement in the form of KangPisMans finger gestures. The myth that comes from the mascot of KangPisMan is about the friendliness and concern of the Sundanese people for the environment.

Abstract
In the United States, cyberspace is a world that is very important in all sectors of peoples lives. The virtual world provides information distribution and is a vital communication medium, both for the government, trade, academia and private sectors. The virtual world in the United States supports hundreds of trillions of very important transactions, such as electricity grid services, sanitation, health services, law enforcement, and emergency calls. For the US government, information technology is very important for almost everything, such as communication and sharing information in daily work, research and development, collaboration with educational institutions and the private sector, command and control in the military, intelligence work, and logistical, managerial work , and administrative government. Second, for the United States military, they are very dependent on global networks. The United States military global cyber network consists of 15,000 local networks and 7 million computers connected by more than 100,000 telecommunications circuits throughout the world. Meanwhile, the spread of the use of information technology and computer networks which later became the center of US strategy also caused its own problems. Dependence on cyberspace results in exploitation of the fragility of the United States. This has the potential to provide an opportunity for opponents to obtain important knowledge such as plans, capabilities, and military operations of the United States. In certain cases, opponents can even disrupt communication and disrupt the civil and economic infrastructure of the community. This study aims to comprehensively understand the importance of cyberspace in US foreign policy. By using qualitative methods researchers will analyze in depth the virtual world priorities for the United States, especially in its foreign policy.

Abstract
One of several factors that influence students successfully when understanding the various concepts contained in the diagram is the use of effective visual reading strategies. The results of previous studies prove that students comprehension of the diagram is still low, although diagrams are often used to facilitate students in understanding concepts. This is a descriptive study involving 20 high school students in Bandung. The research aims to analyze the relation between visual comprehension strategies and students comprehension toward plant morphology diagrams. The students are asked to analyze the morphological diagram of magnoliophyte plants for 15 minutes. The strategies emerge from students will be analyzed and categorized into low-level strategies, high-level strategies, and metacognitive strategies Then the students will be given questions to measure the level of comprehension after learning a morphological diagram of Magnoliophyta plants. The results showed that many students do a more low-level strategy that tends to memorize, to rereads diagrams, and to text signaling. It suits to the level of students comprehension about plant morphology that is still in the low category. The outcome shows that knowledge of plant morphology possessed by high school students was still at the level of memorization.

Abstract
Household waste which is included in domestic waste can be a source of disease if it is not managed properly. Ecovillage is a West Java provincial government program to foster villages in managing the environment, one of which is waste management. The community is given an understanding to be able to sort and choose waste and make useful waste and economic value. Inorganic rubbish is sold to waste banks managed by the community itself, then sold, while organic waste is used as compost as fertilizer when growing vegetables in the yard. This descriptive study aims to explain the management of household waste in the ecovillage kampong wangun. The result of 34 houses in ecovillage on average household waste produced two weeks, inorganic waste consists of 20 kg mineral water packaging, 20 kg flavored glass drink, 8 kg screened plastic, 15 kg bucket, 25 kg carton, 8 kg duplex, 25 kg of shard, 13 kg of iron, 16 kg of shard bottle, 10 kg of crackle and 10 kg of aluminum, used sacks and styrofoam while organic waste consists of 14 kg of vegetable waste. Household waste management in the ecovillage building has been implemented but has not been optimally implemented by the community. Education level, income level, behavior towards environmental hygiene also influence the community in their role in managing the environment. Suggestions given include activating solid waste management groups, the government plays an active role in fostering and financing waste management as well as implementing disciplined solid waste regulations.

Abstract
Dengue fever is an acute disease caused by the dengue virus. Dengue fever is still a public health issue in major cities in Indonesia, one of which is Palembang. Based on the profile done by Palembang City-s Public Health Office in 2017, dengue fever cases in the area from year to year tend to fluctuates. To get the overview of the number of dengue fever cases in the upcoming years, time series forecasting methods are used, namely the Exponential Smoothing method and the Autoregressive Integrated Moving Average (ARIMA) method. Afterward, the results of predictions from the two methods are compared. Forecasting using the ARIMA method gives the smallest MSE and MAE results of 108077,877 and 172,424, respectively, compared to the Exponential Smoothing method. This means that the ARIMA method is better at predicting the number of dengue fever cases in Palembang in the coming years.

Abstract
This study aims to analyze knee joint implants from Ti6Al4V alloys using experimental and simulation methods with Finite Element Analysis (FEA). The experimental method was designed to observe the microstructure, crystal size, and chemical composition of Ti6Al4V. The simulation method is designed to analyze total deformation, maximum principle stress, and maximum shear stress with time and load variations. This study uses SEM, XRD, and XRF analysis to obtain data from the experimental method while the FEA simulation uses ANSYS software. Simulation is done based on the activities of walking, jumping, and walking down stairs for 0-0.01 seconds. SEM results indicate that Ti6Al4V has parallel strokes after the cutting process and resembles the shape of needles that regularly resemble weaving. The XRD results show that the crystal size is 2.906 x 10-5 nm. Then, the XRF results show that Ti6Al4V has 85% Ti, 2.7% Al, and 4% V. The FEA analysis results show that the knee joint implant has a total deformation of 0.00013637 mm in walking activity, 0.00015165 mm in jumping activity, and 0.00015706 mm in activity down the stairs. The maximum shear stress is 1.0852e7 Pa in the running activity, 1.4383e7 Pa in the jumping activity, and 1.2498e7 Pa in the activity down the stairs. The maximum principal voltage on the activity goes 1,404e7 Pa, at the activity jumping 1.7546e7 Pa, and on the activity down the stairs 1.6171e7 Pa.

Abstract
Based on a preliminary study conducted in one of the international schools in Bandung, the implementation of STEM is only done once a semester. The perceived constraints are the unavailability of teaching materials. Science learning that is integrated with engineering design will facilitate students to be able to make product designs. STEM learning with engineering design will train students to use scientific and mathematical knowledge in making products. This will make learning more meaningful in overcoming real problems even by professional engineering workers. By using quantitative descriptive methods, showing the results of the average value of 8.25 engineering abilities, the feasibility of teaching materials in the category is very feasible and the understanding of students is 94%.

Abstract
This study aims to describe the results of design optimization and characterization of mechanical properties of knee implant with SPSS software and characterization using SEM, CRD, and XRF. Optimization is focused on optimizing the total deformation value from human activity of walking, jumping, and downstairs to determine the optimum design of the knee implant. While the characterization of the material is intended to determine the morphology using SEM, chemical composition using XRD, and crystal structure using XRF. The finding of this study is that optimization of total deformation shows that the first design has the lowest maximum average deformation value, that is 0,00014836 mm. While the results of SEM characterization showed that there were many parallel strokes on Ti6Al4V alloys, so that they were not resistant to damage from abrasive particles. The XRD test shows that the crystallinity peak is at position 40.5189182 degree which is indicated by the crystal orientation index 200 reaching 29.35 counts (cts), and Full Width Half Maximum (FWHM) at an angle of 0.2880282 degree which has an atomic distance along the length of 2.22455 amstrong with a relative intensity of 100%. And the XRF test shows the highest chemical content of Ti6Al4V alloy is Ti, amounting to 85.12%. The limitation of this study is that optimization is based on total deformation on three human activities. While the characterization is done by using SEM, XRD, and XRF tests. Optimization and characterization of implants can be the basis of the process of manufacturing knee implants. The results showed that the first implant design was the optimum design based on the total deformation. Then in terms of characterization, it appears that the material is in accordance with the human body.
