This paper examines the effectiveness of law enforcement in society from the perspective of legal sociology. The goal is to explain the extent to which law enforcement can be effective in society. To obtain data from the problem, the author uses the library research method to collect information relevant to the topic or problem to be studied. The type of data used in this study is secondary data obtained from library materials or literature that have a relationship with the object being studied. The results of the study show that the effectiveness of law enforcement has not been maximized. This is marked by the fact that it is not easy for the law to be enforced in cases involving elites or officials. The law should apply to all circles, not recognizing social stratification in its enforcement, but the reality that occurs is inversely proportional to the principle of law, the law is used as a tool for those who have interests. Therefore, the sociology of law is present to examine the impact of the enactment of a law in society, so that social phenomena can arise and develop in society. The sociology of law and the effectiveness of law are very closely related, because what will be discussed in the sociology of law will not be separated from the assessment of how far the effectiveness of law exists in society as part of social phenomena.

Research using Charles Sanders Peirce's semiotics in animated films is based on his triadic approach, namely icons, indexes, and symbols, which are used to understand the hidden meaning in every visual and narrative sign. In the context of film analysis, semiotics functions as a tool to dismantle and understand the structure and meaning contained in visual and narrative elements. This analysis can be done using Peirce's icon, index, and symbol approach. Researchers see how these signs play a role in forming the film's main theme or message. Researchers interpret the meaning of these signs in the social, cultural, or ideological context represented by the animated film. This approach is important for understanding how animated films reflect or influence social views on the themes discussed, such as the role of mothers or families. This interpretation also involves analyzing whether these signs contain social criticism or certain moral messages. Based on the results of the analysis, the audience not only sees the mother as a character but also as a symbol of inspiring strength, which can ultimately shape the audience's perception of the importance of the role of mothers in everyday life. Indirectly, the peace that occurs because there is a strong mother figure in carrying out the rebellion, the strength that was born within her because of the sad circumstances of life, the heartbreaking loss, the circumstances full of suffering. From the film it can be seen that the strength and sacrifice of a mother is extraordinary.

Contract law plays a key role in trade and business. Failure to fulfill obligations in an agreement, known as default, can include non-fulfillment, delays, or performing actions not aligned with the agreement. The aggrieved party is entitled to seek compensation for the default. In a service agreement case resolved through arbitration, the Respondent was found to have defaulted. Despite both parties agreeing to all terms and performing the contract without objection, the Respondent was ordered to pay compensation under Article 1248 of the Civil Code, which includes the concept of "fraud." The author aims to analyze how default in service procurement is resolved through arbitration and whether the arbitral panel’s decision to impose compensation is justified according to the Civil Code and the contract. The research employs a normative legal approach, focusing on literature and statutory regulations. The findings show that both parties committed default, yet the arbitral panel only adjudicated the Respondent, as the Claimant was not counter-sued. Moreover, the Respondent's actions cannot be classified as fraud. The compensation imposed by the arbitral panel based on Article 1248 of the Civil Code should be seen as abuse of circumstances, not fraud..
