Utilization of a mobile device with the Android operating system that is used as a supporting medium and supplement in improving learning outcomes combined with demonstration and discovery learning or demon-disco learning methods is needed to help students improve learning outcomes in vocational competence subjects in hydroponic crop cultivation in vocational high schools Kristen Terang Bangsa, because the use of android-based applications can provide new experiences regarding the use of information and communication technology, as well as provide opportunities for students to be able to learn more independently.
The concept chosen as a learning media is to explain the material about understanding, introduction of parts, types, and quiz containing questions about hydroponic plant cultivation. This research uses the Research and Development (RnD) product development method, using 6 out of 10 stages research that is the potential and problems, data collection, product design, design validation, design improvement, product trials.
The results of this study are to produce learning media in the form of Android-based applications. The validity value of media experts is 2.6 which is declared feasible, while the validity value of material experts is 3.6 which is declared feasible, and is able to increase the average value in the subject of vocational competence in hydroponic cultivation in Christian Terang Bangsa Vocational Schools which initially 67 (with 13 students who had not yet reached KKM) to 80 (with 4 students who had not yet reached KKM).

Daily rainfall characteristics is important in the anticipation of natural hazard events, such as floods and landslides. In this study, daily rainfall data from the Global Precipitation Climatology Project One Degree Daily (GPCP1DD) dataset are used to analyze the rainfall frequency, intensity and extreme rainfall indicators over the Indonesian Maritime Continent. A threshold of 1 mm is used to define a wet day. The analysis is conducted over the whole domain and several sub domains. It is revealed that the rainfall patterns over Indonesia are shaped by the frequency distribution of rainfall intensity over different seasons. Heavy rainfall (greater than 15 mm/day) generally determines the rainfall peak season over a specific region. It is also shown that the land areas receive more frequent and more intense rainfall than the ocean areas.

Fluid flow velocity in physics can be found on the principle of venturi meter. The Fluid flow concept is easy to understand if visualized. We need a learning media of fluid velocity, so the concept can understanding. Design of this tool aims to help students understand the fluid flow velocity. Data is taken automatically by Arduino-based water flow sensor, with speed change at the speed knop. Based on the design result of the tool which can be obtained by measuring the fluid flow velocity at a speed greater than 0.36 m/s, and proved by graph analysis logarithmic between velocity values of magnitude theory (Vtheory = 0.5x + 0.7934 m/s ) and tool speed (Vtool = 0.5825x + 1.129 m/s). The speed difference between the theory and the tool indicates the magnitude of the frictional speed due to the turbulent flow. So it can be concluded the design of this tool can be used as a learning media  to help students in understanding the topic of fluid.

A musical instrument is a device created to produce sound. The price of musical instruments themselves varies depending on the type of instrument and the quality of the material used to make the instrument. At NU 07 Brangsong Middle School, there were no instruments except tambourines. That is because there is no funds to buy a musical instrument. The school allocates more funds to buildings or school buildings and scholarship assistance for underprivileged children and intelligent children. Thus students at the school cannot practice or hone their skills in music. From these problems can actually be solved by an arduino-based Piano, Harp, Marching Bell Digital instrument using laser light and LDR. Because this tool can be made at a low cost and can function more than one musical instrument. The working system of this tool is that there are several lasers that will emit light directly on the LDR sensor (in pairs). And when a pair of laser beams and LDR number one are blocked by an object or hand it will emit a piano sound with a "DO" motif. Furthermore, when a pair of laser beams and LDR number two are blocked, it will emit piano sound with the "RE" orientation and so on. This tool is also equipped with buttons that function as a selector of the type of sound that will be generated and the desired octave.

Whiteboard is one of the learning medias used by the teacher in classroom. It has a great role in physics teaching and learning process. As media of learning, a whiteboard also has an important role in students’ thinking process. This paper discussed about the design of sliding whiteboard based on students’ assimilation of thinking in information processing that written on the whiteboard. The result of sliding whiteboard designs served as a prototype. The prototype was made from 10 cm x 18 cm plywood and rope as a slider. This prototype is expected to became an alternative model in addition to fix stage or theater seat model. In addition, the whiteboard sliding model will be accompanied by a module and user manual. Impact of the prototype on student learning was discussed.

The objective of the study is to determine the characteristic of moisture sorption isotherm from "gaplek" flour fortified with protein from red bead tree flour using various modeling and being observed from the monolayer moisture content and its absorption types. This research used 5 salt solutions and storage temperature of 298K, 308K, and 318K. The models used were Brunauer-Emmet-Teller (BET), Guggenheim-Anderson-de Boer (GAB) and Caurie model. The monolayer moisture content was around 5.07 – 8.53% db. kb value of GAB model was around 0.5941-0.6252. c value of GAB model was around 16.0588-23.4111. C value of BET was around 32.7241-306.5000. Whereas the c value in Caurie model was around 1.1419-1.2769. The equilibrium and monolayer moisture content on ‘gaplek" flour fortified with protein from red bead tree flour was decreasing as the temperature going up. GAB constant value indicated that the process of moisture absorption on the "gaplek" flour fortified with protein from red bead tree flour categorized in type II.
