Abstract

The resistance of a wire conductor depend of the wire material. Copper wire formed into a coil shape an effective form to produce a large resistance. Copper wire resistance influenced bytemperature about it. Coil of copper wire has a good response at low temperature changes produced by liquid nitrogen. This response is shown by the index value determination (R2 = 0.999) which is close to the value 1,that means changes in temperature approaching a linear response to changes in a voltage. The results can be used as a basis for the design of the low-temperature measurements cheaper

Abstract

Energy is one of the basic human needs, both in the form of electricity and energy in the form of heat / gas. The increase in Indonesia's population has increased by 1.3% every year, this is comparable to the increase in energy needs. Current conditions illustrate that the fulfillment of energy needs is sourced more from fossil materials that cannot be renewed, therefore a solution is needed to overcome these problems by finding and finding potential alternative energy sources that can meet human needs. One of the energy that can be utilized is biogas. Biogas is a process of fermentation of organic matter that produces methane gas. Organic materials available in nature are abundant, one of which is organic matter derived from water hyacinth. For this reason, a research study is needed by identifying the potential of biogas energy from water hyacinth. This research is an experimental research, the data collection technique is done by quantitative methods. The tools needed are a manometer, thermometer and biogas reactor. This research was conducted by measuring the temperature and pressure produced by biogas made from organic water hyacinth. The results obtained showed that the biogas produced from water hyacinth produced a gas odor that was relatively not too stinging and the gas formation process was faster. Gas pressure measurements are carried out using a monometer by calculating the difference in the height of water pressure in the U pipe. Measurements of pressure changes are carried out for 20 days by conditioning external factors such as temperature and humidity. The study was conducted to examine the effect of adding water hyacinth to biogas organic matter. The results obtained that t count> t table is the value of t arithmetic (8.183)> t table (2.093) and the significance level of 0.000 <0.05. This means that there are differences in biogas production between before adding water hyacinth and after adding water hyacinth.

Abstract

Metro City is a developing city that attracts many new citizens to come and live in the city of Metro. It affects the density and population growth in the city of Metro so it boils down to the increasing need for energy for fuel such as gas and electricity needs. UU No. 33 of 2007 the government seeks to optimize the role of PEMDA and communities and academics to be able to take advantage of the various potential that may be developed in their respective city in meeting energy needs. The survey results show the picture that the city of Metro has potential in the utilization of biogas energy. The availability of this organic material is quite common in Metro city. But the availability of the material has not been classified in number and variety. For that, we need to do research in mapping biogas potential in every area in Metro city. The research method used is the method of documentation, observation, and interview. As for data analysis techniques, conducted qualitatively and quantitatively through the findings of observations in the form of descriptions, calculation analysis, and tabulation. The results obtained show that the North Metro sub-district has the highest potential for biogas development. The most common materials are animal waste derived from cow dung as much as 84% and biogas from plants that are from rice straw (54%) and Tahu/tempe processing waste (38%). Other organic ingredients found are chicken, goat, buffalo, and banana peels. This result shows that the biogas potency of Metro City is best developed that is through the use of cow dung

Abstract

The Indeavorings’ problem of SMA physics laboratory are: lack competence human resource, coordinator of laboratory is as the second teacher job, the laboratory hasn’t been managed well, so far the laboratory cannot been used optimum. To overcame this problem, there is conducted guidance tacnical of laboratory workers, and workshop management of labarotory. The stap include: guidance tacnical for human resource, workshop of manual laboratory management, inventory and labeling, workshop of schedule arrangement, SOP and the implementation. The result are: 1) in general, the physics laboratory of SMA in Metro have fulfilled the infastruture standar, 2) lack of human resource, 2)good management can help the physics experements a run efficient based on the schedule. The problem found that the teachers are difficult to look for the materials and their spacification, so that needed improvement to laboratory management based on ICT

Abstract

Biogas techniques is a way to produce energy with the anaerobic process by utilizing organic ingredients, one of which can be derived from herbs. The quality of biogas production can be viewed by performing the measurement of absolute pressure of biogas. Absolute pressure is the atmospheric pressure coupled with the measured pressure.  The magnitude of the pressure will affect the quality of the flame produced biogas. This study, using the method of observation, and measurements. As for the data analysis techniques,. The findings focused to find the different of biogas production by measuring the change in absolute pressure of biogas. Measurements are done using a manometer. The results obtained show that the introduction by using cow dung retrieved changes pressure biogas occurred on day 3 with pressure 140.565 N/m2, the characteristics of the data graph illustrates the R2 = 0.677. Different results are indicated on the mixing water hyacinth with cow manure, biogas pressure changes happen on day 1 with the characteristic graph of a R2 = 0.976. This condition describes that the mixing of the water hyacinth and cow dung provides distinctions signifikant in accelerating the process of occurrence of biogas.
