Abstract

Relation between hydrogen ion exponent (acidity) cacao pulp with energy pass electrics (conductivity) checked to know how ability of cacao pulp at various level of hydrogen ion exponents in sending electrics and also how relation between cacaoes pulps hydrogen ion exponents ably energies pass the electrics.Research done by two treatment that is prose process and fermentation of thinning of cacao pulp. Its way beforehand look for resistivity value (ρ) from cacao pulp. From the resistivity value obtained by conductivity value (σ) cacao pulp. If connected between cacaoes pulps hydrogen ion exponents with energies pass the electrics out of two the treatment, the result is progressively low degree of acidity of cacao pulp, energy pass the electrics is progressively decline.Relation between hydrogen ion exponent with electrics conductivity at cacao pulp at fermentation process yield equation = 2,84782 + 1,01789 e [-(x-2,5)/0,626)] and at thinning process yield equation σ = 3,13506 + 0,46513 e [-(x-2,5)/0,20194). On file energy at cacao pulp is known that longer ammeter galvanometer network is attached smaller the electric current so that the energy still be small.

Abstract

Instrument for examine the accuracy of sensor SHT11 has been build. This system consists of a sensor SHT11 as temperature and humidity sensor that connected to Atmega8 microcontroller port as controlling and reading signal from sensors, and LCD to display the value of sensor measurements. Instrument examines result states by using of microcontroller BASCOM AVR language program, the sensor sensitive of temperature and humidity is very good. The graphs that showed by SHT11 sensor tend to assemble to form a line. Form of graphs that tend to form lines as shown also shows that the measuring results are more accurate.

Abstract

A research about quality of drinking water in some refill stations in the Manokwari city in terms of electrical resistive values. The research method used is the experiment method by taking samples of water in some refill stations and putting it into containers, then voltages is applied for each container. The results showed that by applying higher voltages, the resistive will decreases due to the movement of ions in water are faster. This is caused by polarization and then will effect for greater current flows. Electrical resistive is increase after processing showing that the content of electrolytes in water is getting less which means that with the increase in electrical resistive, the water quality will be better.

Abstract

This research aims on measuring and knowing the electricity current resulted from husk-ash. The husk-ash is the remainder of burning process which contains inorganic compound. Because of this compound, husk-ash can produce electricity. The husk-ash used in this research is made of burned paddy trunks; the research used simple electro-chemistry method (primary cell). In the analyzing process, copper (Cu) and zinc (Zn) are used. While the parameters are electrodes distance, width of the electrodes and items amount variation. The result is that there is electricity current produced from the paddy husk-ash, with a requirement the smaller distance between the electrodes, the wider the size of the electrodes and the more the  amount of the items, the electricity will be and the longer its ability to store the electricity.

Abstract

A research about water transportation rate through electro-osmosis with reverse DC voltage polarity system has been done. This research was conducted to determine the optimum value of water transportation rate in electro-osmosis system. Distance variation between anode and cathode, variation of electrode material and amount of anode are three factors to obtain optimum value. Water volume that can be flow out of the media is a parameter of optimization. The test of the system is done by applying DC voltage that has pulse pattern. As the result, optimum distance between anode and cathode is 15 to 20 cm. Meanwhile a pair of stainless anode and chopper cathode is a pair of optimum electrode. Varying the amount of anode indicates increasing rate of water transportation only in condition that the material of anode and cathode are the same and the number of anode is more than cathode. Use the same electrode produce reduction potential of zero which cause anode become no reactive, so that the volume of water release is equal to the number of anodes.

Abstract

This research aims to find out how the application of cooperative model in SAVI type to increase students’ result of learning in the class XI IPA SMA Adventist Manokwari, so that in the process of learning physics, students have a good value and they do not think that physics is a very difficult lesson. The instrument used is an assignment test for cognitive measures and LKPD for psychomotor measures. This research using the Classroom Action Research method (CAR). The results of this research indicate that, in cycle I the total cognitive value of each student 83 with 100% classical completeness, and the total psychomotor value of students 93 with 100% classical completeness. Cycle II the total cognitive value 88 with 100% classical completeness, and the psychomotor 94 with 100% classical completeness. This shows that, learners learn to increase.
