Abstract

Expert’s Testimony is the information of a person who has special expertise for the purpose of examination in a criminal case and must be given in court. An expert must provide information for justice, as well as possible and according to knowledge in his area of expertise. The expert's testimony from the police is still questionable on the independence and justice of the defendant, the expert must be independent and fair in giving explanation there should be no influence from internal or external parties. There are still many expert testimonies from investigators who are highly doubtful of their independence and deemed inappropriate to be made expertly by academicians, but in the Criminal Procedure Code it is not clear whether the expert's testimony from the investigator is allowed or not. Therefore the author interested in conducting research related to the validity of expert testimony from investigators. The author conducted research with normative legal research methods supported by interviews are expected to help answer the research and the source of interviewed is from the academics and practitioners. In the absence of clear rules, the expert's testimony from the investigator will be the pros and cons but if it refers to the understanding and the main purpose of expert testimony in the Criminal Procedure Code, it is unlikely that the expert's expertise is allowed because it will not be free, independent.

Abstract

Penelitian ini bermaksud untuk mengetahui pertumbuhan dan kelangsungan hidup larva ikan tengadak yang diberi Brachionus diperkaya wortel sebagai sumber beta karoten. Larva ikan tengadak yang berumur 1 hari setelah menetas dipelihara dalam toples dengan volume 2 liter diisi air sebanyak 1 liter dengan kepadatan 20 ekor/L sebanyak 12 buah. Toples ditempatkan dalam ruangan heatchery dan dilengkapi dengan aerator. Penelitian ini menggunakan 4 perlakuan dengan 3 kali ulangan yaitu A (kontrol/tanpa pengkayaan), B (Brachionus yang diperkaya wortel 40 g/L), C (Brachionus yang diperkaya wortel 60 g/L) dan D (Brachionus yang diperkaya wortel 80 g/L). Pengkayaan dilakukan dengan cara menginkubasi Brachionus selama 2,5 jam dalam larutan yan mengandung wortel yang telah diblender. Pertumbuhan dan kelangsungan hidup larva ikan tengadak yang diperkaya dengan wortel ternyata lebih tinggi dibandingkan dengan pertumbuhan dan kelangsungan hidup tanpa pengkayaan. Namun perlakuan yang terbaik didapatkan pada perlakuan D dengan pertumbuhan berat sebesar 0,58%, pertumbuhan panjang 6,38% dan kelangsungan hidup 61,67%. Kata Kunci: larva ikan tengadak, Brachionus sp, pertumbuhan, kelangsungan hidup, pengkayaan, wortel.

Abstract

Community empowerment in improving the knowledge to make a generator by using the recycle of magnet of the motorcycle is part of a community service-based research throughtraining manufacture of generators. This generator can be used to change of mechanicalenergy into the electrical energy. Where as the mechanical energy is obtained from theturbine screw. This training method contains material about the introduction of thegenerator and proceed with the process of manufacture of generators by using recycle ofmotorcycle magnet coil manner. Generators are made tested with the 3 phase of motors asearly movers to get the magnitude of the voltage output of the generator. After the outputvoltage is obtained then followed by using the turbinesscrew, windmills or otherpropulsion to drive the generators. Magnet motor that is made into a generator consists ofseveral magnetic poles are 6, 8 and 12 poles. Mechanism of the generator is expected tohelp the community in generating electrical energy as a power source of the electricalpower and that does not depend anymore on electricity company such as PLN for lighting,drying, cooling and others. Through this training, the potential flow of a river or irrigation water in the village of Kemumu can be utilized by the villagers to meet the need forelectrical energy. Where electrical energy can be used to increasing the economy valueand daily life of rural communities Kemumu. Of the training conducted, it was found thatthe generator capable of producing an electrical voltage of 106 volts with the rotationdrive of screw turbines is 876 rpm and 12 pole magnet generator. The generator with anoutput voltage of 6 obtained by 78, 4 Volt with one load of 15-watt incandescent light bulb.And using four load of 15-watt incandescent light bulbs obtained 58,8 Volt output voltageby using a magnetic generator 8 poles. From these results can be concluded that thegenerators by using the recycle magnet of motorcycle by the community can generate an electric voltage.Keywords: Generator, PLTMH, Electrical Energy, Magnet Motor, Turbin Screw
