THE SYNTHESIS AND NMR STUDY ON THE STABILITY OF DIMETHYLMETHOXOPLATINUM(IV) COMPLEXES

he synthesis of two stable platinum(IV) complexes containing methoxo ligand, [Pt(CH3)2(OCH3)(OH)py2] (1) and fac-[Pt(CH3)2(OCH3)(H2O)3] (2), has been successfully performed. Complex 1 was prepared by oxidative addition reaction of cis-[Pt(CH3)2py2] with dry methanol, and a subsequent reaction of 1 with 70 % HClO4 in water produced the platinum complex 2. The stability of complex 2 in acidic aqueous solution was investigated and monitored with 1H and 195Pt NMR. The platinum complex 2 was found to be quite stable toward hydrolysis and no -hydride elimination was observed. Keywords: Methoxoplatinum(IV), NMR, complex stability, hydrolysi

Anticancer Activity Study of Modified Artocarpin Compound from Pudau Plant (Artocarpus kemando Miq.)

This research is a continuation of the successful isolation of artocarpin from the root of Artocarpus kemando Miq reported in our previous study. In the previous study, the artocarpin was characterized with UV-Vis and FTIR techniques. In this follow-up investigation, the artocarpin was subjected to a transesterification reaction using acetic anhydride and pyridine as catalysts, and the product of the reaction was specified as compound 1. The compound 1 was further characterized with different techniques to gain more complete data and then tested for anticancer activity test against P-388 murine leukemia cells. Characterizations of the compound 1 using 1H-NMR and 13C-NMR techniques suggest that the modification reaction resulted in the conversion of the -OH groups at C2' and 4' at the artocarpin molecule to -OOCH3, and based on the MS analysis, the compound was proposed to have the molecular formula of C30H32O8. Another important feature of compound 1 that should be noted is the significant improvement in stability compared to the unmodified artocarpin. Anticancer activity tests against P-388 murine leukemia cells revealed that compound 1 has an IC50of 2.35 µg/mL, confirming that the compound is categorized as an active anticancer agent and suggesting that the compound has promising potential that deserves further investigations. Doi: 10.28991/ESJ-2023-07-03-05 Full Text: PD

PEMUTUSAN HUBUNGAN KERJA (PHK) DITINJAU DARI PASAL 1 UNDANG-UNDANG NOMOR 13 TAHUN 2003 TENTANG KETENAGAKERJAAN JO. UNDANG-UNDANG NOMOR 2 TAHUN 2004 TENTANG PENYELESAIAN PERSELISIHAN HUBUNGAN INDUSTRIAL DI JAKARTA PUSAT (Analisis Putusan Nomor 370/Pdt.Sus-PHI/2020/PN.Jkt.Pst)

For workers, the issue of Termination of Employment (PHK) is a complex problem, because it has a relationship with economic and psychological problems. Economic problems due to layoffs will cause loss of income, while psychological problems are related to the loss of one's status. On a broader scale, it can propagate into unemployment and crime problems. This is of course contrary to the ideals of the founding of the Republic of Indonesia as stated in the 1945 Constitution. Article 27 states “Every citizen has the right to work and a decent living for humanity. The purpose of this study is to find out the process of resolving layoffs on the grounds that efficiency has been determined by Law Number 2 of 2004 concerning Settlement of Industrial Relations Disputes, knowing the arguments regarding legal protection of workers' rights as compensation for layoffs can be seen in Decision Number 370 /Pdt.Sus-PHI/2020/PN.Jkt.Pst. In writing this thesis, descriptive method is used, namely normative legal research. Normative legal research is research by only processing and using secondary data. The results of the research on the Settlement of Termination of Employment for reasons are not regulated by Law Number 2 of 2004 concerning Settlement of Industrial Relations Disputes, only for the settlement of disputes over layoffs in general. In principle, the settlement of layoffs, especially layoffs for reasons of efficiency, must first be resolved through a deliberation process for consensus between the two parties without the intervention of a third party (tripartie), if it fails, then proceed by means of mediation. The next process is continued through mediation. If the bipartie settlement and mediation also fail, then consolidation will be continued. If there is no result in this case, then the process will be continued by going through the litigation process. The legal protection of the rights of workers/laborers as compensation for layoffs must be paid by the employer based on the type of layoff that occurred to the worker/labourer concerned. If we look at the case in Decision Number 370/Pdt.Sus-PHI/2020/PN.Jkt.Pst. That there has been a termination of employment at pt. Pulau intan bajaperkasa construction which in the decision of the Court of Industrial Relations and in the decision of the Supreme Court, gave a decision rejecting all claims filed by the plaintiff.Keywords: Employment, Termination of Employment, Work Agreement Deadlin
