Authors: Syofyan Elvi Roza , - Revalin Herdianto
Published: July 2019

Current water use practice in Tampo Irrigation District is thought as inefficient, since water from main canal is drained to neighboring stream without further use by downstream farms. The remaining paddy farm receives less water from the same source canal. As the result the farms could only harvest once per year. A new irrigation scheme is proposed by diverting water back to the main canal to be used by farms downstream the canal. The proposed method is by using DEM and GIS information, coupled with computation of current water use of the existing farms.The study is begun by identifying the existing farms in topography, irrigation networks, and water use. We use 30 m DEM by ASTER GDEM, coupled with Google Earth to identify stream networks and to delineate basin. The results are confirmed with field measurement in which elevation of structures such as weir, gates, hubs are recorded using GPS. Pertinent points in the field are also recorded by GPS. The existing farms are delineated and marked. Water flow rate are measured in the field using traditional method.We found that the existing water use is insufficient to irrigate the irrigation district. Instead of improving efficiency of the irrigation scheme, water needs additional supply by various means.Otherwise crops cannot be increased more than once a year. We identified another potential water source near the irrigation network that can be directly connected to the existing network. This could irrigate another 100 hectares land.

Students are required to practice firsthand the theories about stone construction that have been studied. Stone work or often called masonry is wall or brick installation work for floor, wall, or fence. In practicum stone, the material used is artificial stone like brick and can also natural stone by using an adhesive substance usually known by the name of spesi or mortar.Mortar or spesi is one of the building materials that serves to glue the pairs of bricks, brick, stucco and so on. Mortars consist of sand, cement and water. In a stone work practicum where the work is not permanent (unloading pairs) then the cement material is replaced by lime which is a temporary binder. So far, the rest of the mortar use for the stone practicum is just thrown away because it cannot be used anymore, therefore it takes alternative utilization of the former mortar, for that the author tries to research by using it to make paving blocks. Paving blocks or concrete bricks for floors are a component of building material made from a mixture of hydraulic cement or the like, aggregates and water with or without other additives which do not reduce the quality of the paving blockThe study used comparison between paving block with mixed composition of mortar, cement and water mixture and paving block with standard mixture composition ie cement, sand and water.

Fiber from oil palm empty fruit bunches (OPEFB) can be used as a raw material for the production of composite board.  Gambier can be used in a natural adhesive because of its high tannin content.  Appropriate material to veneer the board and the correct temperature and pressing time are needed to improve the quality of this composite board. This research was to discover the optimal temperature, needed to make woven bamboo veneer composite board from OPEFB fiber and  gambier based adhesive that can fulfill the Indonesian National Standards for veneered composite boards and the pressing time required for the board to reach thermal equilibrium. Results showed that both temperature and pressing time have a significant influence on density, moisture content, thickness swelling and modulus of rupture (MOR) of the boards but not on the internal bond strength or the compression strength parallel to the grain.  Multi-layered composite board pressed at 1300C has weaker physical and mechanical properties than that pressed at  1450C, or 1600C.  Twenty-five minutes of pressing time yielded a better product than 15 minutes and the combination of 25 minutes and 1450C proved to be optimal for the curing of the gambier based adhesive used with 8.4% moisture content fibers. Use of woven bamboo veneer resulted in boards that reached the density, moisture content, thickness swelling at 24 hours (PT24) and MOR National standards SNI 03-2105-2006 for standard veneered particle board however it failed to reach the standard for modulus of elasticity (MOE).

Wind energy sources in coastal areas of Indonesia are generally one of the potential renewable energy sources (renewable energy resources) that are abundant, environmentally friendly and renewable. Savonius wind turbines can produce relatively high torque even at low wind speeds. Because it is very well developed to produce electrical energy. To get a large amount of electrical power, a large turbine construction is also needed which also requires a large amount of money, of course. For this reason, the dimensions of this wind turbine construction need to be developed, known as aspect ratio (Ar). Ar which has been studied is the cross section of the blade, as well as other values. Whereas the arch depth or blade length of type U is still likely to be studied. Therefore it is necessary to do research on type U blade arcs to get more power than before. Experimental method by making a prototype savonius type U wind turbine with 2 blades. The parameters varied only in terms of the ratio of arc length and blade cross section, other parameters followed the previous study. The expected experimental results get the aspect ratio (Ar) of the best blade in capturing wind energy and producing large electrical power.

Together with advancement in transportation technology, there is a need to study current technology on transportation. Various research have been conducted on pavement to achieve a strong, durable, and economic construction. One of the constructions is Hot Rolled Sheet – Wearing Course (HRS-WC) or widely known as thin concrete asphaltic layer. Concrete asphalt is a flexible pavement with high structural strength and widely used in Indonesia as road pavement. Therefore the characteristic of the mixture is highly affected by type and percentage of filler in the mixture. In the last two decades, design methods are developed based on analytical method which require stiffness modulus and structural values of the material. During this period many research have been conducted on the methods to improve performance of asphaltic concrete by modification of materials as well as material substitution.The main objective of this study is to evaluate the impact of substitution of standard filler of HRS-WC with clay mineral from Gunung Sarik, Padang, on Marshall properties parameters such as stability, density, VIM, VMA, VFB, flow, and MQ. This aim is achieved by analyzing Marshall properties of the mixtures.Our study shows that the substitution of standard filler with clay mineral from Gunung Sarik with variations from 25%, 50%, 75%, and 100% has no significant impact on optimum asphalt content and other Marshall properties such as Density, VIM, VMA, and Flow. These values do not vary from mixtures using standard filler.

multilevel concepts and experiences that allow them to breakout of the room.
Breakout Edu is designed from these sessions offering students multilevel
questions, gamifications, and using technology tools to enhance the education
experience. The purpose of this paper is to review research studies to learn if
using Breakout EDU in a classroom setting will improve student engagement
through communication, collaboration, critical thinking, creative innovation,
and confidence. The results
of this study show that Breakout Edu do not just offer exposure to technology
but a higher level of thinking and collaboration among peers.

Authors: Putri Chery Chaen , Hermawanto Denny
Published: July 2019

Front cavity depth of microphone has influence in the determination of laboratory standard microphone sensitivity. Therefore this parameter is included in the measurement uncertainty budget. To determine microphone sensitivity accurately, it is necessary to measure the actual front cavity depth instead of using nominal value. This paper explains the measurement of LS1P and LS2P standard microphone front cavity depth using optical depth measurement facilities at SNSU-BSN and its effect on determining microphone sensitivity. The measurement was obtained from 4 positions distributed over the diaphragm for each microphone. The front cavity depth measurement result for LS1P is 1,94 mm ± 0,01 mm and for LS2P is 0,48 mm ± 0,01 mm  These results comply with IEC 61094 Measurement Microphones-Part 2: Primary Method for Pressure Calibration of Laboratory Standard Microphones by Reciprocity Technique as the results are within the permissible range.

Densitas merupakan parameter penting pada suatu produk khususnya dalam perdagangan yang menggunakan volume sebagai basis pengukuran. Penggunaan metode uji densitas yang harmonis akan menghasilkan data yang saling mendekati sehingga salah satu pihak baik penjual atau pembeli tidak saling dirugikan. Metode uji merupakan salah satu faktor penting yang menentukan kualitas dan keabsahan suatu hasil uji. Metode uji yang digunakan dalam analisis harus valid dan terverifikasi dengan baik sehingga hasilnya pun dapat diakui. Standar ISO 6883 : 2017 tentang animal and vegetable fats and oils -  determination of conventional mass per volume (litre weight in air) merupakan standar yang disusun secara internasional untuk menguji nilai densitas pada lemak atau minyak yang berasal dari hewan dan tumbuhan. Namun hingga saat ini belum ada data verifikasi metode tersebut khususnya untuk produk crude palm oil (CPO). Verifikasi metode dilakukan melalui uji akurasi menggunakan certified reference material (CRM) yang telah diketahui nilainya dengan pasti dan presisi  dengan menggunakan sampel CPO. Hasil verifikasi metode menunjukkan bahwa nilai akurasi metode tersebut adalah 99.44 % dengan nilai simpangan baku relatif 0.08% sedangkan simpangan baku relatif pada uji presisi metode tersebut adalah 0.35 %. Hasil tersebut menunjukkan bahwa metode uji ISO 6883 : 2017 memiliki kualitas dan performa yang baik dalam melakukan pengujian densitas pada produk CPO. Metode tersebut dapat dijadikan standar acuan dalam penyusunan standar CPO.

Cognitive Skills and Economic Preferences in the Fund Industry
Authors: Farago Adam , Holmén Martin , Holzmeister Felix , Kirchler Michael , Razen Michael
Published: July 2019

By running a battery of incentivized and non-incentivized experiments with fund managers from four countries in the European Union, we investigate the impact of fund managers' cognitive skills and economic preferences on the dynamics of the mutual funds they manage. First, we find that fund managers' risk tolerance positively correlates with fund risk when accounting for fund benchmark, fund category, and other controls. Second, we show that fund managers' ambiguity tolerance positively correlates with the funds' tracking error from the benchmark. Finally, we report that cognitive skills do not explain fund performance in terms of excess returns. However, we do find that fund managers with high cognitive reflection abilities generate these returns at lower risk.
