Abstract

A witness is a person who can provide information for the purposes of investigation, prosecution and justice regarding a criminal case that he himself heard, saw for himself and experienced for himself. The rules regarding the procedures for how a person can be presented as a defendant and then whether he will then be sentenced or not are regulated in a series of writings called the Criminal Procedure Law. In handing down a criminal decision, according to article 183 of the Criminal Procedure Code, a judge may not impose a crime on someone unless there are at least two pieces of evidence. One of the pieces of evidence that can be used by a judge is witness testimony. Children can be witnesses in a criminal trial. However, the validity of children's testimony is often still in doubt and further investigation is needed regarding the validity of children as witnesses in court. In Indonesia itself, the definition of child is regulated in various statutory regulations, including Law Number 23 of 2002 concerning Child Protection. A child is defined as someone who is not yet 18 (eighteen) years old, including children who are still in the womb. This article will explain more specifically the involvement of children as children in conflict with the law in the case of children who are witnesses to criminal acts, the position of children as witnesses in criminal trials, and the strength of the evidence of child witnesses' statements in criminal trials.

Abstract

Plastic waste is a type of inorganic waste that takes around 50-80 million years to decompose in the soil. Plastic waste contributes to 90% of the waste in the ocean, causing damage to coastal ecosystems and having implications for the degradation of coastal ecosystems. To overcome this, the Mayor of Bontang has prepared a legal product that regulates the use of plastic waste and one of the efforts the author has made to tackle plastic waste in Bontang City is to create a tool that can convert plastic waste into fuel oil. The aim of this research is to determine the process of utilizing plastic waste into fuel oil and to determine the volume of fuel oil produced from processing plastic waste. This research is experimental research using the pyrolysis method. The trial results of processing plastic waste into fuel oil show that: the technology that is practically used is using the slow pyrolysis method with simple tools, the use of plastic waste into fuel oil is very effective to implement. Meanwhile, the volume of fuel oil for 1.4 kg is 350 ml at a temperature of 225℃ with a residence time of 4 hours. However, if the temperature is increased to 400-600℃, it is likely that the oil produced will increase.
