Abstract

Keamanan pangan merupakan aspek penting dalam menjaga kesehatan masyarakat. Salah satu bahan berbahaya yang kerap ditambahkan dalam makanan adalah boraks. Penelitian ini bertujuan untuk mengidentifikasi keberadaan boraks secara kualitatif pada jajanan sempol ayam yang beredar di Kota Pontianak. Penelitian bersifat observasional dengan pendekatan deskriptif kualitatif. Sebanyak enam sampel sempol ayam diambil dari enam kecamatan di Pontianak melalui metode cluster sampling. Identifikasi dilakukan menggunakan uji kertas turmerik dan uji nyala api. Hasil pengujian menunjukkan bahwa lima dari enam sampel tidak mengandung boraks, sedangkan satu sampel (S3) memberikan hasil positif pada uji kertas turmerik tetapi negatif pada uji nyala api. Perbedaan hasil ini menunjukkan kemungkinan keberadaan boraks dengan kadar rendah yang tidak terdeteksi pada uji nyala api. Penelitian ini menunjukkan perlunya analisis kuantitatif lebih lanjut untuk memastikan kadar boraks dan meningkatkan kesadaran masyarakat tentang bahaya penggunaan boraks dalam pangan.

Abstract

Jamu cekok, an Indonesian traditional medicine to increase children appetite, has not passed preclinical or clinical trials. The rhizomes that make up jamu cekok such as pakai bahasa latinnya contain ethyl p-methoxycinnamate which is toxic, thus potentially harmful to the children. Therefore in this study we aim to determine the Lethal Dose (LD50) value of jamu cekok using the OECD 425 method as well as to observed the histopathological change in the liver in female Rattus norvegicus L. This study used an analytical experimental design with the OECD 425 method to test the acute toxicity of jamu cekok. The test rats used were in accordance with the OECD 425 protocol with an additional 2 negative control rats. Jamu cekok in the form of decocta were given once on the first day of the acute toxicity test and observed for 14 days. On the 15th day, rats were euthanized, dissected, and hepatic organs were taken to make histopathological preparations with Hematoxylin-Eosin staining. Analysis of hepatic damage was assessed using Histopathology Scoring Manja Roenigk and tested by Kruskal Wallis method. The results showed the LD50 value of decocta extract of jamu cekok was >5000 mg/kgBB. Observations of body weight, behavioral tests, organ index, and macroscopic hepar of test rats showed no signs of toxicity. However, The statistical analysis for histopathology test showed that there was a significant difference (p<0.05) between the negative control group and the 5000 mg/kgBB treatment group. In conclusion, the administration of jamu cekok was categorized as practically non-toxic but it can caused reversible hepatic damage at a dose of 5000 mg/kgBB.

Abstract

The increasing Antimicrobial Resistance (AMR) drives the need of new antibacteria as drug candidate to eradicate resistant bacteria such as ESBL (Extended Spectrum Beta-Lactamase) producing Escherichia coli. Extract and fraction of Sapindus rarak fruit contains numerous saponin compounds, which exert potential antibacterial effect by binding to the bacterial cell membrane. The purpose of this research is to analyze and evaluate Sapindus rarak fruit extract and fraction antibacterial effects through in silico and in vitro approach. Molecular docking is conducted to identified compounds contained in Sapindus rarak fruit against Penicillin Binding Protein (PDB ID: 6NTZ) using Autodock Tools. Antibacterial testing of Sapindus rarak fruit extract and fraction is also conducted with disc diffusion and microdilution. In silico docking study resulted in potential activity from raraoside A and rarasaponin V, which showed affinity tinggi through their binding energy whilst interacting with the active site of the receptor protein. No inhibition zone was detected on extract and fraction, yet lowest minimum inhibition concentration (MIC) was detected at 2.5×104μg/mL on water and n-hexane fraction Sapindus rarak fruit ethanol extract. This weak antibacterial effect tends to happen to crude extract than to compound isolates. Hence, Sapindus rarak fruit fraction exhibits weak antibacterial effect on ESBL producing E. coli, but certain isolates might be potential to be further researched. Sapindus rarak fruit isolates such as raraoside A and rarasaponin V is potential to solve antimicrobial resistance by acting as a plant based antibiotic.

Abstract

This study aims to analyze sodium (Na) levels and estimate the daily intake (EDI) from the consumption of three shellfish species: blood mussels (Anadara granosa), kepah (Polymesoda erosa), and nipah (Geloina coaxans) obtained from Al Mahira Market and the Alue Naga area in Banda Aceh. Sodium concentrations were determined using Atomic Absorption Spectrophotometry (AAS). The results showed that sodium levels ranged from 1186 to 4656 mg/kg (wet weight). The highest EDI was found in blood mussels from Al Mahira Market at 0.997 mg/kg body weight/day (3.489% of the recommended daily sodium intake). In comparison, the lowest was observed in nipah clams from the exact location at 0.247 mg/kg body weight/day (0.866%). Overall, sodium intake from shellfish in both locations contributed less than 5% of the daily sodium limit. These findings indicate that shellfish consumption poses a low sodium-related health risk, although frequent or high intake may still contribute to long-term hypertension risk.
