Abstract

In contemporary times, using food coloring agents is necessary to capture attention. The extensive use of synthetic food coloring agents has raised significant health concerns. Red spinach, a plentiful vegetable in Indonesia, contains anthocyanins that give it a reddish-purple color. The presence of anthocyanins makes red spinach a promising natural coloring agent. This research aims to identify the optimal operational conditions for extracting anthocyanins from red spinach, with the ultimate goal of applying these findings in developing innovative food products. The fixed variables included 20 grams of dried red spinach, a 10-minute extraction duration, and distilled water as the solvent. The independent variables were microwave power levels (100, 300, 500 W) and the material-to-solvent (M/S) ratio (1:10, 1:15 g/mL). The results revealed a moisture content of 7.6% in red spinach. The highest yield was achieved at 100 W with an M/S ratio of 1:15 g/mL, yielding 80%. The best anthocyanin extract was determined based on the highest anthocyanin content, which was obtained at 300 W with an M/S ratio of 1:15 g/mL, resulting in 56.93 mg/L. Anthocyanins were stable at low temperatures (4°C) but highly unstable at high temperatures. Sensory testing to determine consumer acceptability showed no significant taste difference between beverages with added anthocyanin extract and those without. The resulting taste was mild, and the extract's color was appealing. Therefore, the anthocyanin extract from red spinach can be used as a natural coloring agent, replacing hazardous synthetic food colorants.

Abstract

Polygamy in Indonesian law is positioned as an exception to the principle of monogamy and is permitted only in a limited manner under strict requirements, including court authorization and the consent of the lawful wife. Nevertheless, unauthorized polygamous practices remain prevalent, giving rise to legal uncertainty regarding marital status and causing both material and immaterial harm to the lawful wife. This study aims to analyze the juridical implications of Law Number 1 of 2023 for unauthorized polygamy, particularly with respect to legal certainty and the protection of the lawful wife’s rights. The research employs a normative legal method with statutory, conceptual, and philosophical approaches, examining provisions of marriage law, the National Criminal Code, as well as doctrines of criminal law and Islamic law. The findings indicate that Articles 411 and 412 of the National Criminal Code provide legal certainty by affirming that the validity of marital and sexual relations is determined by recognition under state law. Unauthorized polygamy that fails to comply with family law procedures may be classified as the criminal offense of adultery or cohabitation, both of which are complaint-based offenses. This legal construction strengthens the protection of the lawful wife by positioning her as a legal subject with control over the initiation of law enforcement processes. The study concludes that the reform of the National Criminal Code is not intended to criminalize polygamy as an institution, but rather to prevent its misuse in ways that undermine the rights of the lawful wife.
