Abstract
Helmet is a protective device whose safety standards are strictly certified. Unfortunately its high safety standards sacrifice user-s convenience when using it. Efforts to use air vent on the helmet is complained of still not enough. Thermoelectric modules offer solution that can be used to solve this problem. Thermoelectric models of lamps reduce temperature of surrounding environment when used as an electrical voltage. This research is commonly known as thermoelectric helmet. Perfecting the helmet design is an ongoing research step that needs to be done. Thermoelectric design focuses on how to make the hot side of thermoelectric able to release heat to the environment properly. If the hot side isn-t good at releasing heat, it will affect the temperature on the cold side which is a problem that must be prevented. Thermoelectric helmet that currently under investigation still uses a fan to remove heat from thermoelectric module. The disadvantage of thermoelectric helmets with cooling fans is they are heavy and not compact in size, as well as the fan also requires additional external power that consumes a lot of power. The utilization of fluid flow on a flat plate could theoretically be implemented in this case. Air flowing around the helmet when used driving has a high enough speed so it could theoretically be used to increase rate of heat transfer by convection. Supporting data, design and performance testing of helmet prototypes are the main issues to be examined in this study. Target of this research is to create a comfortable helmet by utilizing a thermoelectric module but in a compact and concise form.

Abstract
Utilization of solar energy is limited in Indonesia, especially in the field of photovoltaic which is done by converting solar irradiation into electrical energy using solar panels. The electrical energy produced by solar panels can be used for cooking process using electric stoves to warm the food in the meatball seller. The benefits of electric stoves is it can be use to stabilize temperature meatball soup, so that the meatballs always expand and are ready to sell. The temperature used to maintain the quality of the meatballs is ranging from 70-80 ℃. The electric stove can stabilize the soup as much as 10 liters using a 160 Watt dimmer input using 120 V voltage and output current of 0.74 A. The installation using 4 solar panels and each panel has a power generated of 100 Wp. The performance of the Off Grid 400 WP PLTS has been sufficient to meet the need for an electric stove that operates for 6 hours.

Abstract
In Indonesia, plastic waste has become an important problem at this time, because it causes environmental pollution problems. With this, further action is needed regarding the treatment of waste utilization, one of which is by converting waste into liquid fuel. Some types of rubbish that we often encounter are plastic bottles such as plastic cups, plastic bottle caps, childrens toys and margarines and others, which is one of the types of PP (polypropylene) waste. The development of current plastic waste treatment technology is to convert plastic waste into fuel oil by utilizing plastic waste to be processed as plastic fuels such as premium fuel, diesel and kerosene. Polypropylene type plastic is the type of plastic that is most widely used in daily life because it has good mechanical properties with low density, heat and moisture resistance, and has good dimensional stability. Some of the technology used to convert plastic waste, among others, by using the method of high temperature named Thermal Cracking, namely heating polymer or plastic material without oxygen, this process is usually carried out at temperature. This process includes the pyrolysis process ,. The results of the thermal cracking process will produce fuel oil by condensation with the cooling process, when the pipe releases steam that occurs in a heated pressure vessel, thus producing steam that is condensed using water until it changes shape to become liquid. One of the results of the pyrolysis process is Polypropylene Plastic is a fuel that is equivalent to fossil fuels. In this study, researchers analyzed the octane number of Polypropylene liquid fuel that was heated and the Distillation process with a temperature variation of 80 Celcius degree, 100 Celcius degree, and 120 Celcius degree produced Polypropylene fuel equivalent to a standard fuel with an octane number of 93.8. So that this fuel can be used on vehicles .

Energy consumption for households is used for various purposes, including for cooking, lighting, air conditioning, and others. The cooking process is an activity in the household sector with considerable energy consumption. The fuel that is often used for the cooking process is LPG for urban areas and firewood for rural areas. LPG is a fuel whose price is relatively high and fluctuates with time. In addition, this fuel often has problems with uneven distribution in some areas. While the supply of materials is also increasingly limited over time due to problems with the environment. One solution to overcome these problems is to utilize renewable energy, especially solar energy which is always available throughout the year. The results obtained in this study are the design and manufacture of solar power plant installations that are integrated with electric stoves. This installation is able to heat as much as 20 liters of water and maintain water temperatures up to 70 oC for 6 hours.

Abstract
Gunung Pasang plantation is located in Panti-Jember. The Gunung Pasang plantation actually already has a Francis type microhydro turbine with a power output of around 30 kW. However, this power is still too small when compared to energy needs in plantations which can reach 90 kW. A study is needed to find out the potential of micro-hydro energy in the Gunung Pasang plantation as a reference for developing micro-hydro energy in the plantation. Potential studies are carried out by measuring the discharge using a current meter and measuring the difference of elevation using a automatic level and altimeter. The result of measurement of potential river flow discharge in the dry season is 0.202 cms. The difference in elevation measured at the first point is 54.19 meters and the second point is 113.09 meters. Microhydro power potential based on the results of calculations by taking a discharge of 0.18 cms for the first point is 69.61 kW and for the second point 145.27 kW. Utilitation of potential power in the second point will be able to meet the electricity needs of the plantation. Economic feasibility analysis is needed if the micro hydro potential is to be developed.

Abstract
Improving production system quality, especially in the efficiency of coal combustion, is a must to optimize the electric energy production of a power plant. To maintain customer trust, towards an international standard distribution process, it needs innovation in combustion monitoring. Overheating conditions frequently occur and could break the camera due to limited information on combustion temperatures received by the user. From these problems, this study aims to design a classification system for monitoring the combustion process in the boiler or furnace. Combustion area captured by the Adafruit AMG-8833 IR camera and continued with the extraction and segmentation of thermography analysis and neural network (NN). This study utilizes the features of temperature conversion in each image segment in the form of HSV (Hue, Saturation, Value). Hue parameters (H) and value (V) parameters are used in the classification process for its large degree of red to green differences with a significant range at each temperature. Those parameters are the input of the Artificial Neural Network along with the average & overheating temperature as the classification target. The average error of this system is 0.08559% for the image classification with training data of 64x45 inputs, 16 neurons, and the best performance at 10th repetition.
