Bioactive compounds are chemical compounds formed through metabolic processes in plants, contributing to their beneficial properties. Cocoa fruit, derived from 22 cultivated Theobroma species, contains a variety of bioactive compounds that offer several health benefits. Identifying these bioactive compounds in plants can be achieved through extraction using various solvents, depending on their polarity properties. This study aims to explore the content of bioactive compounds in dried cocoa fruit peel (Theobroma cacao L.) extract, focusing on variations in solvent polarity. The results of the study showed that the 96% ethanol extract (polar solvent) of cocoa fruit peel contained a range of bioactive compounds, including flavonoids, tannins, alkaloids, and saponins. Ethanol, being a polar solvent, effectively extracted a variety of bioactive compounds due to its ability to dissolve polar substances. This extract is significant due to its wide range of potential health benefits attributed to the presence of flavonoids, tannins, alkaloids, and saponins, all known for their antioxidant, antimicrobial, and anti-inflammatory properties. Additionally, the acetone extract (semi-polar solvent) of cocoa fruit peel also contained alkaloids, flavonoids, tannins, and saponins. Acetone, as a semi-polar solvent, was able to extract a variety of compounds with moderate polarity, making it a versatile solvent for bioactive compound extraction. The presence of alkaloids and saponins in this extract indicates its potential use for various medicinal purposes. On the other hand, the n-Hexane extract (non-polar solvent) of cocoa fruit peel produced primarily alkaloids and terpenoids. Hexane, being non-polar, tends to extract non-polar compounds, which include alkaloids and terpenoids known for their various biological activities. In conclusion, the study demonstrates the varying effectiveness of solvents with different polarities in extracting bioactive compounds from cocoa fruit peel, which can be utilized for health-promoting purposes.

Tahun 2019
Tentang Komisi Pemberantasan Korupsi

Concerning the Corruption Eradication Commission

Abstract
This article aims to analyze the existence and reformulation of appropriate legal policies towards Law Number 19 of 2019 on the Corruption Eradication Commission, in combating corruption. The symbolic action taken by numerous anticorruption activists in the context of the funeral of the Corruption Eradication Commission (KPK) due to the ratification of Law No. 19/2019 reflects the integrity crisis of the institution. Several rules that have become polemic, namely the KPK's status as a State Institution, KPK’s status staff as a State Civil Apparatus, the presence of the Supervisory Board, and the rules regarding the Termination of Investigation and Prosecution. By applying the normative juridical research method, this study intends to provide a reformulation model for Law No.19/2019. Apart from not fulfilling all the principles in the Law on the Establishment of Legislation, which makes this regulation formally flawed, several articles in it can also harm KPK, some of those articles have been declared unconstitutional and conditionally unconstitutional based on the Constitutional Court's decision. Therefore, the implementation of reward and punishment within the KPK, along with personal evaluations supported by reverse proof of assets owned, should be an effective input for KPK to become a better institution.
Artikel ini bertujuan untuk menganalisa eksistensi dan reformulasi kebijakan hukum yang tepat terhadap Undang-Undang Nomor 19 Tahun 2019 tentang Komisi Pemberantasan Korupsi, dalam rangka memperkuat pemberantasan korupsi. Tindakan simbolis yang dilakukan oleh sejumlah pegiat antikorupsi dalam rangka pemakaman Komisi Pemberantasan Korupsi (KPK) akibat pengesahan UU No. 19/2019 mencerminkan adanya krisis integritas pada lembaga tersebut. Beberapa aturan yang menjadi polemik, yaitu status KPK sebagai Lembaga Negara, status kepegawaian KPK sebagai Aparatur Sipil Negara (ASN), hadirnya Dewan Pengawas (Dewas), dan adanya aturan mengenai Penghentian Penyidikan dan Penuntutan. Dengan menerapkan metode penelitian yuridis normatif, studi ini hendak memberikan model reformulasi terhadap UU No.19/2019. Selain dari tidak terpenuhinya seluruh asas-asas dalam Undang-Undang Pembentukan Peraturan Perundang-Undangan yang menjadikan peraturan ini cacat formil, beberapa pasal di dalamnya juga dapat merugikan KPK, di mana sebagian telah dinyatakan inkonstitusional dan inkonstitusional bersyarat berdasarkan putusan Mahkamah Konstitusi. Sehingga dengan ikut diterapkannya reward and punishment dalam lingkup KPK, juga evaluasi personal dengan pembuktian terbalik mengenai harta kekayaan mereka, seharusnya menjadi masukan yang efektif bagi KPK untuk dapat menjadi institusi yang lebih baik lagi.

Abstrak:
Diarrhea can be defined as a condition in which a person defecates with more liquid feces than usual and with a frequency of three or more times in 24 hours. Diarrhea is closely related to the occurrence of stunting cases. Diarrhea generally attacks toddlers because their immune systems are still weak and vulnerable. WHO and UNICEF policies in the treatment of diarrhea are the provision of oralit and zinc, based on research over 20 years. Iron plays a role in various physiological processes of the body, one of which is the immune system. The purpose of the study was to determine the relationship between hemoglobin levels and compliance with zinc intake with the incidence of recurrent diarrhea in toddlers at the Jaury Jusuf Putera Makassar Academic Hospital. The research design used was a non-experimental analytical cross-sectional study, namely a study conducted observationally to see the relationship between hemoglobin levels and compliance with zinc intake with the incidence of recurrent diarrhea, without providing treatment to the research subjects. The sample in the study was toddlers who experienced recurrent diarrhea at the Jaury Jusuf Putera Makassar Academic Hospital in March - May 2024 as many as 32 people. The results of the study showed that there was a relationship between hemoglobin levels and the incidence of recurrent diarrhea (p = 0.015). And there was a relationship between compliance with zinc consumption and the incidence of recurrent diarrhea (p = 0.004). It is recommended that health workers provide more education and control over the use of zinc drugs given in the management of diarrhea, as well as educate to maintain normal hemoglobin levels in toddlers. So that it can reduce the prevalence of recurrent diarrhea.
