Abstract
Indonesia is a tropical country that has two seasons, rainy season and dry season. The wetting and drying of soil due to changing of the seasons caused change on soil properties such as moisture soil water content, effective soil porosity, soil suction etc. During rainy season, rainfall infiltration caused increasing of moisture soil water content in a soil slope, tends to reduce soil shear strength and followed by slope instability. In this study soil column experiment was set up with rain gauge station and YL-69 sensor to monitor rainfall infiltration and soil moisture water content. A wireless sensor network with low power wide area network technology integrated with the cloud to observe rainfall intensity and soil water content in soil column with realtime monitoring. The study focused on improving the accuracy of rainfall intensity and soil water content sensors readings using regression methods. The experiment results showed that rainfall intensity was observed accurately while for the YL-69 sensor, the error reading was 2.2% and the error reading capasitive soil moisture sensor was 1.8%.

Abstract
Rives is a source for human and all creatures inside. Water quality of a river will give impact to all creatures surrounded it. Nowadays, there are so many rivers have been exposed to pollution. Pollution came from industrial waste or garbage. Besides causing pollution, waste that has accumulated in the river can cause some problems. Such as flooding in the rainy season caused by so many pollutions inside. Therefore a river monitoring system is needed that can be used to monitor the height and quality of river water. The river monitoring system with multi-hop communication it can be solved to reach more distance. While to make monitoring easier it can be used real-time monitoring. Sending data with low packet loss would give data results better. The value of packet loss can be determined by the delivery interval of time and distance. Packet loss testing is done with variations in the interval of sending 500 ms, 750 ms, 1000 ms, 2000 ms, and 3000 ms. While variations in the distance used are 10 meters, 50 meters, 100 meters, and 300 meters. The best packet loss results at 500 ms sending interval are 48.9% when the distance between nodes is 10 meters. when the sending interval of 750 ms is 25.2% with the difference between nodes 10 meters, when the sending interval of 1000 ms is 1% when the position between nodes is 10 meters, when the 2000 ms sending interval is 3.2% while the distance between nodes is 10 meters, while the sending interval of 3000 ms is 1.9% with the distance between nodes 10 meters. So it can be concluded that the best packet loss happened when the distance between nodes is 10 meters. The worst packet loss results at a 500 ms sending interval is 81.25% when the position between nodes is 300 meters, when the sending interval of 750 ms is 61.25% with the difference in location between nodes 300 meters, when the sending interval is 1000 ms is 35.91% and the distance between nodes is 300 meters, when the 2000 ms sending interval was 53.20% with a 300 meter distance difference and when the 3000 ms delivery interval was 65.71% with a 300 meter node distance. So it can be concluded that the worst packet loss happened when the distance between nodes is 300 meters

Abstract
Political parties as pillars of democracy need to be organized and refined to realize a democratic political system, especially to realize good governance, both at the center and in the regions. This paper seeks to examine the relationship between the function of recruitment / regeneration of political parties with the phenomenon of the minimal number of pairs of regional head candidates that occur in several regions in Indonesia. In practice political parties have not optimally carried out the recruitment / regeneration function, this has been seen in the implementation of the local elections so far. There are at least two things that are the reasons; first, political parties still tend to recruit candidates who are not members of the political parties. Secondly, the emergence of regions that hold regional elections is only followed by one pair of candidates and also supported by many political parties.

Abstract
Muffler industry has been closely related to wastewater processing before disposal into environment. Using an aerobic method, the wastewater can be converted into friendly of environment. Unfortunately, waste processing approach before its disposal into the environment has disadvantages. These disadvantages can be approached by a combination of clean production application and wastewater processing product. The production process in a company does not only result in the preferrable end product, but also provide non product output. This non product output may take the forms of material,water, and energy used for the production process but it cannot be the desired end product. Therefore, rather than obtaining added value, it tends to cause cost inefficiency for the industry. Besides, the non product output in the form of contaminant may have negative impact on the community and the environment. The objectives of this study were to identify and to evaluate the efforts of the clean production application by muffler industry in Purbalingga Regency, as well as to provide alternative to obtain good governance as an effort to put the clean production into practice. This study applied a descriptive method combined with engineering by explaining cost calculation for the muffler industry due to the existence of the non product output as compared to the total of production cost. This study revealed the inefficient use of raw material and water as well as hot spots. The calculation of the water, energy and material scales resulted in efficient use of raw material (72.37%), wastewater (82%), and energy (78%). The alternatives for the treatment/improvement dealing with the good governance as an opportunity for the clean production found during the observation were awareness of the required acceptance, monitoring and storage of the muffler raw material storage to produce high quality raw materials, and controlling the water and energy use during the production process.

Abstract
Abstract—Fuel system modification techniques to improve engine efficiency could be the way to slow down the energy crisis caused by the lack of new fuel inventions. The Compression Ignition (CI) diesel engine is one of the most preferred engines for both in-land and marine transportation motors. The advantages of compact dimensions and large generated power make CI diesel engine superior to other engine types. The large number of single CI diesel engines use in small fishing vessel engines and agricultural machinery will contribute substantially to fuel consumption in a cumulative manner. Previous researchs on the modification of fuel system with bi-fuel system High Speed Diesel (HSD)oil – Liquified Petroleum Gas (LPG) system capable of reducing Brake Specific Fuel Consumption (BSFC) up to 24% and exhaust gas opacity up to 68%. Subsequent studies focused on engines with single fuel HSD oil but were injected with superheated steam in 1 atm (abs) 130 oC by utilizing Heat Recovery Generating System (HRSG) using heat of exhaust gas for a flowrate of 1.5 - 4.5 kg/hour. It is capable of delivering the performance improvement of Specific Fuel Consumption (SFC), which is reduced by 8.92% compared to diesel engines without steam injection. Recent research combines the above two modification methods so that diesel will adopt two types of fuel- oil-LPG with additional superheated steam injection resulting from exhaust gas heat cogeneration system. Experimental results of the diesel engine with LPG injection maintained at 0.4 kg/h and 3.5 kg/h superheated steam with an engine variation loading of 0.3-0.7 kWh provide an average AFR of 30.09 and SFC improvement up to 37.2% lower than SFC engine standard with a single fuel HSD oil.

Abstract
Abstract - Anemia among pregnant mothers is a serious issue that may cause pregnancy complications, premature birth that can lead to mortality, and low birth weight (BBLR). Monitoring for anemia among pregnant mothers is quite a phenomenon for midwives and health professionals due to time constraint as it takes time to establish a proper diagnosis. Late diagnosis establishment results in late treatment. Therefore, this paper proposes a web-based rule-based information system using the rule- based algorithm to ease monitoring and detection of anemia among high risk pregnant mothers. The method employed is online rule-based information system to diagnose anemia among pregnant mothers. Respondents input data of symptoms that will then be processed by the information system to generate diagnoses. Resulting diagnoses are displayed as they are. The rule-based method in the information system validates data of symptoms and diagnoses with experts in the field to serve as reference in providing health care information. This is a pre-experimental research with one posttest group. The intervention group (N=10) was given treatment using the information system, while the control group (N=10) was given treatment manually. Interventions were conducted for 20 days, and measurements were carried out on the 21st day using the Technology Acceptance Model (TAM). The anemia detection system for pregnant mothers developed here is proven to be effective in helping anemia detection and has been validated by experts (midwives) and hence, been declared valid. With effectiveness score of 90 %, this web-based rule-based information system is effective in detecting, monitoring, and reporting anemia among pregnant mothers.

Abstract
Abstract - Labor pain is usually severe and only 2-4 % mothers experience light pain during labor. Labor pain is treated pharmacologically, but it comes with side effects of breathing difficulty, lower uteroplacental perfusion, fetal bradycardia, increased need for oxytocin, and it is not cheap to administer. One of the pain management methods available is heat therapy. Heat therapy is conventionally performed using warm water zack or hot water compress using a towel. However, this method comes with disadvantages of unstable temperature, wet media, and non- continuous heat effect. This paper proposes pain reduction method using automatic heat therapy with proportional integral derivative (PID) controller. It makes use of heat from an electric heater attached to metal plate. The PID controller is used to manage the required heat. A temperature sensor is attached to the plate and provides input to the PID controller. Respondents involved were delivering mothers of Stage I Active Phase Respondents were treated with 450cheat for 60 minutes. There were three groups; intermittent group treated with 15-minute treatment, 5-minute pause, and 80th minute stoppage, continuous group treated with non-stop heat that was ended on the 60th minute, and control group given simple pain management by rubbing their backs. Analytical results show an effect of p value < 0.05. Test result on the effect of pain intensity with p value 0.000 means that there is an effect of heat treatment on the reduction of pain intensity for Stage I Active Phase labor.

Abstract
Abstract - Jaundice is a serious health issue. Late treatment of jaundice cases in babies may result in neurodevelopmental disorder and irreversible brain damage. Diagnosis inaccuracy is usually caused by the fact that health professionals and health service providers often rely on visual observation instead of laboratory examination. Lack of expertise in detecting jaundice is a serious matter. This research proposes a method of web-based digital image processing as an alternative for early detection of jaundice based on babies- complexion. Images of babies- complexion and color calibration cards are taken to obtain images for online analysis. Determination of bilirubin levels is carried out using the method of Euclidean approximate distance of RGB values from babies- complexion and those of color calibration cards. Results show correlation of Euclidean distance to bilirubin level of babies of 0.93596 and web-based digital image processing accuracy of 90%. These mean that the information system developed here is capable of detecting jaundice cases. This research was performed observationally in high-risk prenatal ward involving 30 infants as samples.

Abstract
Abstractt—This research was purposed to study the composite behavior and the increased capacity of reinforced concrete beam strength under flexural loading caused by external strand strength without stressing. The specimen is divided into 2 types. Type-I specimen has (150 x 300 x 3200) mm dimension with center point loading, and distance of strand clamp as (U- bars) variable; whereas, the Type-II specimen has (200 x 300 x 3200) mm dimension with third point loading, and the number of strand as variable. The test is carried out by static-monotonic loading, and displacement control. Experimental test results shows that the addition of strand on the lower surface of the beam increase the beams load capacity. However, the use of U- bars affects the stability of the concrete. The tighter distance of the U-bars decrease the capacity of the strengthening occured. The increased load capacity of Type I specimens, S3-150, S5-150 and S9-150 are 33.2%, 17%, and 12.1% against control beam (BK-150), respectively. Whereas, the increased capacity of the type-II beam strength of test specimens B1-200 and B2-200 are 10% and 17% against control beam (BN-200), respectively. And the increase of initial stiffness of beam Type-I test specimen S3-150, S5-150, and S9-150 are 14%, 18% and 5% against control beam (BK-150), respectively. Meanwhile, the increase of initial stiffness of Type-II beam of test specimens B1-200 and B2-200 are 21% and 24% against control beam (BN-200), respectively. This study shows that concrete and strand bonding is not compatible. The concrete has been reaching the limit strain, as well as the steel reinforcement in the concrete has been in yielded; meanwhile, strand that has fy is much higher than fy of reinforced steel,is still in elastic condition.

The variation of filler content used are 3%, 4.5%, 6%, 7.5% and 9% with cement filler as comparator. The test was conducted by using wheel tracking machine on temperature of 60˚C, 45˚C and 30˚C. The test result shows that the optimum filler content using granite dust in the AC-WC mixture is 3%. Meanwhile the optimum filler content on the asphalt concrete using cement filler is 7.5%. Thus, it shows that the higher temperature cause the ability of maintaining the wheel track decreased. Furthermore if looking at the relation between dynamical stability, deformation depth and deformation velocity on filler concentration is not linear.

Abstract— Climate change and advanced urbanization level followed by the changing function of an area affect to the amount of water absorption area. It causes puddle and flood in city, include Cimahi, West Java, which is in the last 10 years has been surrounded by flood and puddle. To avoid the flood case in Cimahi, the re-identification and flood-factor inventory are needed. The identification and inventory are using the simplest method (literary study from any source), start from discussing session with Cimahi government, interviewing and filling questioner to the citizen who live in flood and puddle area, measuring river and drainage profile, counting the capacity of river and drainage, until simulating the 2-dimension and 3-dimension of flood and puddle. The result of the identification and inventory is shown in Flood- Prone-Zone Map and Puddle-Prone-Zone Map. According to Cimahi-sFlood-Prone-Zone Map, it shows that the flood-safe area is about 110,747 ha (2,70%), the not-flood-prone area is about 494,233 ha (12,05%), the flood-prone area is about 2016,474ha (49,18%), and the very-flood-prone area is about 1478,799 ha (36,07%). According to Cimahi-sPuddle-Prone-Zone Map, it shows that the puddle-safe area is about 128,616 ha (3,14%), the not-puddle-prone area is about 551,246 ha (13,44%),the puddle- prone area is about 2702,826 ha (65,92%), and the very-puddle- prone area is about 717,556 ha (17,50%). The Flood-Prone-Zone Map and the Puddle-Prone-Zone Map can be used as a reference for the Cimahi Government in formulating the policy of regional development.

Abstract
CRIMINALIZATION OF FUNDING IN CRIMINAL TERRORISM IN INDONESIA By: Sukamarriko Andrikasmi.SH., MH Faculty of Law, University of Riau Pekanbaru, Indonesia Email: kreasiimuda@gmail.com ABSTRACT Terrorism is a crime that is currently a hot issue in Indonesia, attracting the attention of the international community and even terrorism is also a conversation between countries, and not a few of the issues of terrorism can affect the relationship between countries both bilateral and multilateral Criminalization of funding of terrorism applies to everyone who intends to do or intends to commit a crime of financing terrorism in the territory of the Republic of Indonesia and / or outside the territory of the Republic of Indonesia. And also applies to funds related to financing terrorism that are outside the sovereign territory of the Indonesian State. As explained in Article 2 paragraph 2 of the Law on the Prevention and Eradication of the Criminal Acts of Terrorism. The criminal act of financing terrorism as a behavior that is not in accordance with the norm or can be referred to as deviation from the agreed norms turns out to cause disturbance to the order and peace of human life. Such deviation is usually referred to by humans as an offense and can even be said to be a crime which is a social phenomenon and will always be faced by every human being, society, and even the state. The fact has proven, that crime can only be prevented and reduced, but difficult to eradicate completely. This law will be very effective if accompanied by enthusiasm to eradicate criminal acts of terrorism, without any engineering and conspiracy from parties who have full power over a country. If the procedure is carried out correctly, and appropriately appropriate law enforcement of criminal acts of financing terrorism will be able to hinder the process of criminal acts of terrorism in the future from channeling funds. In other words, it can at least stop the funding process. It is more appropriate if the criminalization of terrorism funding is followed by reliable human resources, and other supporting institutions.

Abstract
The performance of a motorcycle engine is greatly influenced by the cooling system. If the heat is released more than it should be then the efficiency will decrease. Thus, the engine block cooling system must be designed optimally. The research aimed to study the effect of motorcycle speed, turbulence intensity, and tilt angle on the heat transfer coefficient of the engine block cooling system. Calculations were performed numerically using a finite volume method. The engine block was modeled as an annular fin cylinder which had a stroke volume of 150 cc, where the outer and inner diameter was 78 mm and 62 mm, respectively, while the fin thickness was 2 mm. The simulated vehicle speed was 40 to 100 km/h at 30 oC air temperature. The turbulence intensity were varied between 0 to 20%, while the tilt angle were 0 to 90 degrees. It was found that there were an optimum condition which give the highest heat transfer coefficient. It can be concluded that the numerical simulation can be used to design an optimal motorcycle engine block cooling system.

Abstract
In daily life, people with visual impairment have difficulty in their activities, especially at home activities. People with visual impairment as of 2017 reached 1.5 percent or around 3.75 million people from the population of Indonesia and more than 253 million people worldwide. The number of blind people who are not small need help to get a good quality of life and independent. Friendly home design for the blind is not yet available specifically. It is a particular difficulty for blind people to access the latest electronic goods or information (news). Then this becomes the basis of this research on how to provide easy access for blind people. This research provides a solution that is designing a prototype of a house that is visually impaired in addition to the use of electronic equipment. This system starts from the microphone as a sensor in charge of picking up sound and then the results are processed by Android and then connected to NodeMCU via Wi-FI. The microphone used is the default microphone of the Android smart phone. By using the speech recognition method the command is enough to say the keywords, Android will manage the sound into a code that will be sent to the microcontroller to perform the task. There are several categories of commands that can be handled, including (a) Turning on / off electronic devices, (b) Providing news information from popular news web portals, (c) Entertainment by playing streaming radio and (d) General information on hours and dates. All planned functions are running properly, there are some features that might be developed further.

Abstract
The focus of this paper is power constrained in wireless sensor networks. We purpose an adaptive transmit power levels based on sensors noise variance and channel conditions. We also investigate its impact on energy saving. First, the measurement results of the sensors are quantized into discrete messages. Second, the quantized data are transmitted to the fusion center where a final estimate is generated. The optimal transmit power levels for each sensor is determined by the sensor noise levels and channels conditions from sensor to the fusion center. The goal is minimized the total transmitting power, while ensuring a given Mean Squared Error (MSE) performance. The sensor will be active when the measurement results of the sensors have low noises variances and the condition of the channel between the sensor and the FC is good and if the conditions are otherwise the sensor is not active with the aim of saving power. For the remaining active sensors, their optimal transmit power levels are determined jointly by individual channels gain, local observation noise variance sensor and the targeted MSE performance. Numerical examples show that an adaptive power levels achieves significantly smaller MSE than uniform power levels for the same average power consumption.

Abstract
The palaces in Cirebon has been established since the 13th century, and still show its existence until now. Then ancient customs and traditions are still practiced until today. The palaces are located along the Java Sea cost and facing northward, which becomes the position maintained by the three palaces. The position of the tombs of the kings is located on Mount Sembung is the north part of the three palaces. There are sacred spaces scattered in various locations outside also within the palace. The sacrality of space and the findings of previous studies show that Palaces in Cirebon have the cosmology perspective within its spatial system. Thus, the aim of this paper is to describe cosmological exploration of the Cirebon palaces. The approach taken is a qualitative method from the findings of previous studies, especially those related to the space system that is formed. Then a dialogue on cosmological theory was conducted. The result of this study is the findings of cosmological results from the location and position of the palaces in Cirebon. The results are expected to give consideration to spatial policy especially for the development of the space in Cirebon.
