ASAS PROPORSIONALITAS DALAM PENGATURAN HAK DAN KEWAJIBAN PADA KONTRAK KERJA BORONGAN PERSPEKTIF HUKUM ISLAM (STUDI DI MEDANG KAMPAI, KOTA DUMAI, RIAU)NIM.: 24203012041Ulan PitriyaniauthorThis study analyzes the legal framework between PT. X and piecework employees regarding the rights and obligations of the parties and formulates an ideal piecework contract based on the principle of proportionality from an Islamic law perspective. The research problem is based on the imbalance in the contract, particularly regarding the company’s authority, the fulfillment of workers’ rights and protection, the imposition of additional obligations, and the distribution of risk of loss. These conditions indicate that the existence of rights and obligations in the contract does not yet guarantee a proportional employment relationship. This study is a qualitative study employing an empirical-juridical approach and field research methodology. The subject of the study is the piecework employment contract between PT. X and pieceworkers in Medang Kampai, Dumai City, Riau. Data were collected through observation, interviews with company representatives and pieceworkers, as well as documentation in the form of Employment Agreements (SPK), laws and regulations, books, journals, and related documents. Data analysis was conducted through data reduction, presentation, interpretation, and drawing of conclusions using the Theory of Labor Relations in Labor Law, the Theory of the Principle of Proportionality, and the Theory of Sharia Contracts with a focus on Ijārah al-A‘māl. The research results reveal two main findings. First, the legal relationship between PT. X and its contract workers constitutes an employment relationship, as it involves an employment agreement as well as the elements of work, wages, and instructions. However, this relationship is not yet fully equitable, as the company has relatively broad authority in determining the continuity of employment, while the workers’ obligations are defined more concretely and the fulfillment of their rights is not yet fully equitable. This imbalance is also evident in worker protections and the allocation of risk of loss, which in several clauses is predominantly directed toward the workers. Second, the ideal formulation of a piecework contract based on the principle of proportionality involves the fair distribution of rights, obligations, authority, benefits, and risks in accordance with the status and contributions of the parties, while clarifying the scope of work, targets, duration, payment of wages, adjustments to targets due to obstacles beyond the worker’s control, limitations on the company’s authority, and protections for workers’ health and safety. From the perspective of Ijārah al-A‘māl, this formulation must ensure clarity regarding the object of the work, the wage (ujrah), the timeframe, and the consequences of failure to fulfill performance obligations, based on the principles of justice.346.02 Hukum Perikatan & Perjanjian2026-10-26UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS SYARI’AH DAN HUKUMThesis
