Abstract

Qiyas is one way to resolve various legal cases whose arguments are not clearly stated in the ur'anqand Hadith. Imam Syafi'i is one of the initiators of the concept of iyas who holds the view that various legal cases that exist in Muslim society which are not yet clearly regulated in the ur'an and hadith can be resolved through iyas, either in the form of iyas aulawi, iyas musawi or qiyas adn . One case that is not yet clear is the type of staple food that is issued as zakat fitrah in Indonesia. The zakat fitrah issued which was the staple food of the Prophet Muhammad saw and the Arabs in ancient times was wheat, dates, cheese, and others. In fact, the majority of Muslims in Indonesia who adhere to the Shafi'i school of thought pay zakat fitrah in the form of staple foods that are commonly consumed, namely rice, corn, sago, etc. Zakat fitrah which must be paid by every Muslim who is still alive in the month of Ramadan and has excess staple food for the night and Eid al-Fitr, if rice is used is 2.5 kg or 3.5 liters per person

Abstract

Ujungmanik Village, Kawunganten District, Cilacap Regency, which is in the Segara Anakan Cilacap area, has natural resources, especially eucalyptus plants, which have the potential to develop the economy of the village community. The biggest problem faced by LMDH Dadi Makmur as a unit that manages the eucalyptus oil business is that after the production of eucalyptus oil distillation, it will produce residual waste from cajuput oil twigs and leaves with quite a large volume and only be left piled up around the yard where the distillery is, causing area storage of essential oil raw materials is narrow and also takes a long time to become organic fertilizer. The innovation offered through this community service activity is implementing a briquette printing machine from eucalyptus oil refining waste which is energy efficient and based on solar panels. The results of the dedication show that the eucalyptus oil waste processing activity in addition to reducing environmental pollution also produces biomass briquettes that can be utilized by the residents of Ujungmanik Village as a leading economic product of Ujungmanik Village.  Keyword: Cajuput oil, briquette, solar panels

Abstract

Electrical energy is one of the most important energies in everyday life so high-voltage electrical equipment has a vital role in maintaining the reliability of electric power distribution. The corona effect is caused by insulation failure in high-rise equipment which results in disrupted electrical power distribution. The purpose of this research activity is to produce a multi-sensor tool to test the condition of equipment in distribution network booths that have experienced the corona phenomenon. The input data from several sensors used, such as the ozone sensor, will detect ozone gas exposed in the 20kv chamber, detection of ultraviolet light by the UV sensor module, and detection of sound frequency from the hissing of equipment through the microphone sensor experiencing corona will be processed by the Microcontroller and if the value is detected exceeds the reference value that has been set, the output in the form of an LCD will display a corona symptom warning message and instruct the buzzer alarm to sound. The results showed that the prototype of the corona detector was able to identify ozone levels with a maximum value of 21.88 ppb, the largest UV index value of 336, and a maximum hissing frequency of 157 dB in distribution cubicles that experienced the corona effect.

Abstract

A coil winding machine for water pumps using a monitoring system is a development of conventional winding tools. In regular coil winding tools, the coil winding process is done manually by rotating the handle as many times as the desired number of turns. The conventional winding tools have problems consisting of inconsistent working speed and operator-dependent winding continuity. Undesirable windings can occur with conventional winding tools, and the winding process requires close supervision. Therefore, the automatic coil winding machine was developed to optimize the coil winding process. The machine utilizes a DC motor to rotate the coil rolls, replacing the conventional roller handle function. This machining method uses an optocoupler sensor. The sensor serves to identify and evaluate the rotation of the roller. In addition, the ATmega8 microcontroller was applied to develop a system that can work automatically. Data collection involves varying the number of wire turns and the wire diameter dimension. The variation is necessary because the number of windings and wire diameter affect pump efficiency and performance. The data testing showed a machine accuracy rate of 98%, with a maximum difference of 1 coil winding in the results. This data confirms that the coil winding machine meets the tool's accuracy standards.

Abstract

Ocean wave power plant is one of the plants that uses sea waves as the main energy. Although the amount of energy is abundant, in Indonesia the use of sea waves as electricity generators is still small. This is due to the lack of human resources to manage the wave energy of sea water. Many research studies on the Oscillating Water Column have been carried out, but it is only limited to a potential or feasibility study to be installed on the coast. Therefore, the focus of this research is to design a sea wave power plant with an oscillating water column system. The working process of the tool begins by adjusting the pwm to drive the motor power window which is connected to the wave arm. When the wave arm moves back and forth, it will produce artificial ocean waves. Artificial waves in the chamber produce compressed air, the air produced is used to rotate the turbine blades that have been connected to the generator to produce electrical energy. The greatest voltage and current is obtained when the wind speed reaches 7.7 m / s and the largest pulley rotating speed reaches 31,9 rpm at the 17 cm water level, which is 3.03 V DC and 6,07 mA. The test results prove that the potential of water waves can be used to generate electricity The development of the capacity of ocean wave power plants can be done by changing the dimensions of the turbines and increasing the capacity of the generator.
