Abstract
Battery development is essential to satisfy green technology trend that requires electric based technology. Lithium-ion battery (LIB) is the most popular battery that has been used in various electric technology. However, LIB has concern on safety aspect by using liquid electrolyte which is prone to thermal failure that leads to flame or explosion. Solid-state battery (SSB) recent development could handle such thermal problem due to non-flammable characteristic of solid electrolyte. SSB also has potential for future main battery candidates due to high energy & power density. Although there are many advantages, SSB also has several problems in recent development. Interfacial stability, low ionic conductivity on room temperature, mechanical properties, etc. need to be studied further to make adjustment for further development. This review would give information regarding recent progress on SSB development from various type of electrolyte and failure mechanism.

Abstract
While a barge is operating, there are hydrodynamics forces influencing motion of the barge. To create an autonomous barge, there are some parameters that must be obtained. There are many methods to generate data for these parameters, such as experiment and computational simulation. CFD method is the best way to obtain the parameters. Besides having a high level of accuracy, CFD method doesn-t require expensive cost compared to the experimental method.

Abstract
Braking system by using friction is critical in electric vehicles. However, the use of excessive friction will cause a decrease in braking performance. One alternative solution is to use the Eddy current braking system (ECB). ECB is a braking system that utilizes eddy currents generated by induction when the rotor rotates due to the magnetic field produced by the stator. This study discusses the use of ECB for electric motorcycle disk braking systems. This study aims to determine the effect of air gap on braking performance of ECB on an electric motor. The finite element (FEM) method was used in ECB performance modeling. The results showed that the need for a combination of motorcycle disks with disks that match the ECB with maximum torque at 12Nm. It can be concluded that using ECB can effectively increase the braking power by reducing friction on the braking disk. It means the ECB system can extend the life of the braking disc.

Abstract
In a disruptive era marked by rapid changes and abundance of information, the occurrence of cognitive biases becomes difficult to avoid. Individuals are more confident in something perceived than the facts and actual data. Emotions are stronger than reason. In a neuro-psychological perspective, people tend to use the limbic system rather than the neocortex in thinking and responding to things. As a result, opportunities for mistakes in making decisions more often occur. In the long run, such conditions will distort the academic climate that promotes rationality and critical thinking. The results of a study of 1000 students of Universitas Negeri Surabaya in seven faculties and postgraduate programs showed that cognitive bias occurred in 81% of respondents. Deprivation is deeper in social science students than exact science students. There is a significant correlation between curiosity and academic performance. Other relevant research shows that students who use intuitive thinking have lower academic performance than students who use reflective thinking. Intuitive thinking also encourages students to cheat and their eating patterns are very risky for health.

Abstract
The javelin throw basically requires an efficient release angle. The angle is at 30 ° to 36 °. Observations made on the ground in novice athletes are used as a single sample because athletes have difficulty directing the javelin to get the correct throw angle. Javelins that are produced with poor ability to release techniques result in the athletes inhibition to get maximum throw performance. This is caused by a stiff wrist. Stiffness in the wrist is one factor that causes inadequate throwing performance. The reason is that a javelin that is not at an angle of 30 ° to 36 ° will find it difficult to reach the maximum distance. Thus, the problem of the ability of the javelin release technique is of particular concern for research. In this situation, the researchers presented a device called the wrist to practice the simulation of the javelin release technique. So, with training using a wrist device, problems with stiffness when removing the javelin can be overcome appropriately.

Abstract
The rapid development of agricultural products industry in Indonesia presents a new challenge for the industry. The high demand for agricultural products makes the industry must think to manage the plantations more effectively and efficiently. One of the problems in plantations is the process and procedure of weighing agricultural products. At this time the process of weighing agricultural products takes a long time and a long procedure. In the industry, processes and procedures for weighing agricultural products as they are today being considered inefficient. Direct weighting at the time of collection is assessed to be rapid and highly beneficial to the industry. But there is a problem when weighing is done directly. If weighing is done directly at the time of collection, then the weighing is done under dynamic conditions. To be able to solve the problems in weighing the agricultural products then proposed a study to build a dynamic weighing system that can weigh dynamically where direct weighing agricultural products can be done at the time of collection. The force transducer will measure the force applied by the weighing system and the load in the form of industrial products. Because the system works in a dynamic state, the forces acting on the force transducer can be calculated using Newtons second law and where is the deformation acceleration of the force transducer which is proportional to the acceleration of the weighing system, is the mass of the weighted system supported by the force transducer and is the mass of the product being weighed. The deformation acceleration of this force transducer is measured using a flat coil.

Abstract
The existence of Tl-208 in thorium fuel cycle is a double-edged sword. Tl-208 is a strong 2.6 MeV gamma emitter, which acts as an effective proliferation barrier while in the same time complicating the spent fuel handling. To ensure the safety of the latter, the buildup of Tl-208 and its parent isotope, U-232, are necessary to be understood. This paper attempts to analyze U-232 and Tl-208 buildup in the Experimental Power Reactor (Reaktor Daya Eksperimental, RDE) fuel based on thorium cycle, using various U-233 isotopic vectors simulated with ORIGEN2.1 code. The simulation result shows that U-232-contaminated fresh fuels ended up with larger U-232 and Tl-208 activities at the end of cycle (EOC) compared with uncontaminated fresh fuel. However, their U-232 build-up rate are lower and even negative at one case. Then, lower U-233 purity resulted in larger U-232 and Tl-208 activities at EOC. This result implies a considerable difference of isotope buildup between the various U-233 vectors. Consequently, the thorium cycle-based RDE spent fuel handling should consider the isotopic vector of U-233 used in fresh fuel.

Abstract
Two floating spheres are attracted to each other, if the initial separation distance is less than several times of diameter. This is also affected by portion of immersed volume of the sphere. The interaction between the two spheres is produced by unbalanced surface tension of each ball with the surrounding fluid. Position of each ball is observed using video camera and then the information is extracted using a in-house software based on OpenCV library. Due to difficulty of maintaining reproducible initial conditions, one the spheres sometimes moves to approach to the second, and not both move to aproach each other. In all these cases spheres position is transformed to center of mass position so that all position data as function of time will show a symmetry with center of mass position. Taking differential with respect to time two times, acceleration of each sphere will be obtained. The this information form of interaction can be deducted. A simulation using molecular dynamics method and theoretical approach will show the relation between form of interaction and the related acceleration function of time.

Abstract
Preliminary study on Modified CANLDE burnup strategy utilization in a helium cooled fast reactor have been performed. The Modified CANDLE burnup strategy is applied so that the reactor can operate using natural uranium fuel. Modified CANDLE burn-up strategy is applied in the radial direction because it is technically easier to implement. In modified CANDLE burnup strategy in radial direction, the active core is subdivided into ten regions with the same volume in the radial direction. When startup, each region contains fuel with different composition. The first region contains natural uranium (fresh fuel). The second region contains fuel from natural uranium burning for 10 years, the third region contains fuel from natural uranium burning for 20 years and so on. In this study, the Modified CANDLE burnup strategy in radial direction was designed using the MCNPX program. The fuel to be used is obtained from the calculation results of 2006 SRAC code system and FI ITB CH1 program. In the process, fuel will be shifted from one region to another until all regions are filled with new fuel. The result of calculation shows the reactor is in critical condition.

Abstract
Innovation is believed as one powerful weapon to survive in modern competitive industry. Both Large organizations (LOs) and Micro, Small and Medium Enterprises (MSMEs) are trying their best to keep up with the innovation within their firms. However, due to its nature in lack of resources both human resource and capital, it is significantly difficult for MSMEs to pursue innovation either in service or product offered. This qualitative study reveals the substantial meaning of innovation in MSMEs and strategy to conduct innovation where it focuses to micro businesses whose owned by students. These research objects are chosen due to their capability in presenting innovation from their educational background and in-depth knowledge. This study found that innovation capabilities is not enough to assure innovation culture in the business especially innovation paradigm to the founder. 2 (two) out of 3 (three) modern innovation choices are more essential to be applied to micro business which are inclusive innovation and collaborative innovation. Where the other 1 (one) innovation type, open innovation is more suitable to LOs. Following to that, this article also put the strategic steps to persevere innovation culture in Micro Businesses.

Abstract
Recombinant growth hormone (rGH) is a product produced by combining genes that are desired artificially (clones) outside the body with the help of cell transformers, in this case growth genes from target fish are isolated and transformed with the help of microbes, such as Escherichia coli, Bacillus, Streptomyces, and Saccharomyces. Utilization of the hormone RGH is to accelerate growth and increase endurance of fish seed. The increase in growth acceleration is triggered by where the hormone rGH will trigger organs associated with growth to increase its growth. The study used a Completely Randomized Design (CRD) with 5 treatments and 3 replications with the volume of water used 30 liters of water and aquarium size 40x30x25 cm ^ 3 each treatment, at a dose of 0 ml / kg (control), 1 mg / kg, 2 mg / kg kg, 3 mg / kg, and 4 mg / kg. The administration of 1 mg/kg, 2 mg/kg, 3 mg/kg, and 4 mg/kg of rGH hormone to commercial feed can affect the growth rate of the discolored wader seed growth. The study is seen in terms of SGR (Specific Growth Rate), Daily Length Growth, SR (Survival Rate) and FCR (Food Convention Rate). The optimal dose for the growth performance of the cakul wader fish seeds. in the treatment of P3 (2 mg/kg), it can be concluded that the higher dose does not necessarily have the effect of increasing high growth. Therefore, the administration of the hormone RGH must be in accordance with the right dose.

Abstract
There are a number of potential agroindustry products to be developed in the border area between countries in Bengkalis Regency, one of which is coconut. The development of coconut agroindustry is important because most people depend their lives on coconut farming. In connection with efforts to increase community economic development, the problem faced is the suboptimal utilization of industrial technology in increasing added value, and the suboptimal role of economic facilities and infrastructure in supporting the production, processing and marketing processes in Bengkalis Regency. This study aims to analyze the added value of coconut agroindustry products. Value added analysis using the Hayami Method. There are three coconut agroindustry products developed, namely copra, dried grated coconut, and coconut shell charcoal. The highest added value of coconut agroindustry products is coconut shell charcoal for IDR. 3,165.79/kg, then dried grated coconut is IDR. 1,057.86/kg, and copra IDR. 243.36/kg. In order to increase the added value of coconut agroindustry products, technology transfer is needed to increase the quantity and quality, as well as variations in coconut agroindustry products. In the process of technology transfer, it is necessary to optimize industrial technology and supporting infrastructure for the economy.

Abstract
Sweet potato is a local food that can help reduce dependence on rice and flour consumption. This commodity is the main source of carbohydrates, after rice, cassava, flour and corn. The usefulness and potential of sweet potatoes as alternative food needs to be developed, especially in rural areas. However, sweet potato commodity has not been considered as an important and high economic value commodity in Indonesia. This is in contrast to developed countries, where sweet potatoes have been used as food and non-food raw materials, among others, used to make noodles, sweet potatoes, desserts, confectionery, soy sauce, flour, wine, vinegar, nata de coco, bioethanol and others. Sweet potato cultivated in Indonesia around 89% is used for food to meet the food needs of rural communities, the rest is for industrial raw materials and animal feed. The content of sweet potatoes includes carbohydrates, vitamins, and minerals. Yellow / orange sweet potato is rich in beta-carotene and purple sweet potato contains anthocyanin compounds (antioxidants). Sweet potato processing is still limited to traditional types of food whose products are considered less attractive when compared to processed flour products. Meanwhile, intermediate products that have been developed include flour, instant flour, and starch that can be used as a substitute for flour (10-100%) in pastry products, wet cakes, breads, and noodles.

Abstract
Herbicides was efficient but caused pollution of water sources, soil damage, and leave toxic residues in agricultural products. Environmentally friendly weed eradication can be done by using bioherbisida, such as Siam (C. odorata) leaf alelopathy. The research was conducted at Laboratory of Indonesian Legumes and Tuber Crops Research Institute (ILETRI) Malang in April 2017 using a complete randomized factorial design repeated three times. The first factors was: C. odorata extract concentration that consisted of: concentration 0% (w/v), concentration of 10% (w/v), concentration of 20% (w/v), concentration 30% (w/v). The second factor was the type of commodity that consisted of: soybeans, mungbeans and paddy. Making simplicia begins with the impregnation of fresh C. odorata leaves at 65 ˚C for 24 hours and then blended. 60, 40, 20 g of the simplicia soaked with 95% ethanol for four hours then each weight added aquades 200 ml and filtered with filter paper. Seeds was tested (arranged) on with CD paper which was wetted firstly with each extract C. odorata leaves concentrations and set aside. During the germination was doing, paper moisture was maintained by adding 10 ml of the extract C. odorata leaves of each concentration level. The observed variables were radical length (root), plumula length, and number of leaves at 4, 7 and 10 dap. The results showed that the leaves extract of C. odorata with concentration of 20% (w/v) and 30% (w/v) had potential as bioherbisida which could control weed growth.
