Abstract

Pomegranate has valuable nutritional content and contains various bioactive compounds, one found in the fruit's peel. The utilization of these bioactive compounds could be used as herbal medicines and supplements, such as antioxidants. This study aimed to determine the antioxidant capacity, phytochemical profile, and pomegranate peel extract grouping using different extracting solvents. The three extracting solvents used were water, 70% ethanol, and ethanol p.a. Antioxidant capacity of the three extracts was measured using the DPPH and CUPRAC methods. We also determined the total phenolic and flavonoid levels and the TLC fingerprint analysis and FTIR spectrum of the pomegranate peel extracts. The 70% ethanol extract owned the largest antioxidant capacity than the other two extracts with a value of 358.67 and 2981.59 µmol trolox/g dried sample using the DPPH and CUPRAC methods, respectively. The three pomegranate peel extracts' total phenolic and flavonoid levels ranged from 287.26–1068.81 mg GAE/g dried sample and 0.24-0.75 mg QE/g dried sample. TLC fingerprint analysis of pomegranate peel extract yielded 2, 6, and 6 bands for water extract, 70% ethanol, and p.a ethanol, respectively. The three extracts can be grouped based on FTIR spectrum data using principal component analysis using three principal components with a total variance of 93%. The results obtained show that using different extracting solvents provides different antioxidant capacities and phytochemical profiles.

Abstract

The objective of this research was to study the potential of cherry leaf extract as natural sanitizer agent for Alabio eggshell in hatching process. A number of 533 of Alabio hatching eggs were used in this study. Hatching eggs produced from College of Vacational Studies IPB University, were collected three times a day. Three hundred thirty-three hatching eggs were divided into five treatment groups. The first group was considered as control, the second was dipping into commercial disinfection, and the third and the fifth gruop were dipping into cherry leaf extract 250 ppm, 500 ppm, and 750 ppm respectively. The results showed cherry leaf extract has secondary metabolite compounds : alkaloids, flavonoids and tannins. All of these secondary metabolite compounds have a role as antibacterial agent. cherry leaf extract 750 ppm shows the same potential as commercial disinfectants in reducing the microbial population in eggshells. The dipping treatment of 750 ppm cherry leaf extract in alabio duck hatching eggs resulted in the lowest embryo mortality rate compared to other treatments (9.3%).

Abstract

This research aimed to determine nitrite and nitrate contamination in wastewater discharge from the smoked fish industry around the fishpond area in Penatarsewu village, Sidoarjo East Java. Samples were taken from ten locations along The Alo River from September to November 2020. Nitrate and nitrite levels were determined by the Standard Method for Examination of Water and Wastewater 4500-NO2-B dan 4500-NO3-B. Nitrite formed a reddishpurple azo dye produced by coupling diazotized sulfanilamide with N-(1-naphthyl)-ethylene-diamine dihydrochloride after a visible spectrophotometer measured the complexes nitrite at wavelength 543 nm. Meanwhile, the Nitrate level was determined by ultraviolet spectrophotometer at a wavelength of 220 nm. The standard nitrite calibration curve was shown by the line equation y= 3,30361x-0,0028 and a determination coefficient of 0.9999. Whereas the standard nitrate was showed by the line equation y=0,2507x + 0,0067 and a determination coefficient 0,9996. The level of nitrate and nitrite in the sample ranged from 0.05-0.93mg / L 1,2-1,6 mg / L. According to a quality standard threshold value for nitrite and nitrate-based on the Government Regulation of the Republic of Indonesia (PPRI) No.82 2001 is 0,06mg/L and 10 mg/L, therefore it can be concluded that some samples are above the threshold value for nitrite level.Keywords: Alo River,  nitate,  nitrite,  smoked fish,  spectrophotometerPenentuan Kadar Nitrit dan Nitrat Pembuangan Limbah Cair Industri Ikan AsapABSTRAKPenelitian bertujuan untuk menentukan tingkat kontaminasi nitrat dan nitrit pada limbah industri ikan asap di sekitar kawasan tambak ikan asap di Desa Penatarsewu, Sidoardjo, Jawa Timur.

Abstract

This study examines how Islam views natural resource conservation. This is a qualitative research with a descriptive approach. Based on the results of the studies that have been carried out, it can be concluded that Islam teaches humans to be responsible for all of Allah's creation, including being responsible for protecting and maintaining natural resource ecosystems. The principle of conservation in Islam is based on mutual care between humans and nature, because basically humans take advantage of the available natural resources. In addition, in the utilization of natural resources, humans must pay attention to balance, not be exploitative and remain proportional so that natural resources are preserved.
