Abstract

Lalapan is a popular food consumed. The increase in population, industrial activities, transportation, use of chemical fertilizers and pesticides has led to lead (Pb) pollution in the environment, contaminating vegetables that are to be consumed and posing health risks. Therefore, research was conducted regarding the analysis of Pb pollutant concentrations in lettuce, basil and cucumber sold in traditional markets and supermarkets in the city of Yogyakarta. Samples were extracted using 65% HNO3 and 37% HCl, and then the concentration of Pb in the samples was analyzed using Atomic Absorption Spectrophotometry. The research results showed that all types of vegetables sold in traditional markets and supermarkets have been contaminated with Pb with concentrations ranging from 0.418 to 1.575 mg/kg, with the highest Pb concentration was found in basil with an average of 1.5156 mg/kg. The average concentrations of Pb in lalapan sold in traditional markets and supermarkets, when compared to the quality standard set by SNI regulation (2009) for cucumber sold in supermarkets N, are still below the safe limit of 0.5 mg/kg for , while the rest have exceeded the quality standard limit. There are significant differences in the concentration of Pb pollutants in vegetables sold in markets and supermarkets, as well as based on sales location, type of vegetable, and vegetable source. The consumption pattern of vegetables ranges from 62-97 g/day and poses health risks as the RQ value is greater than 1. Additionally, it has the potential to cause cancer because ECR > E-4.

Abstract

This study aims to explore the potential of nature, socio-cultural potential, facilities, accessibility, and characterization of society and examine the potential for tourists and analyze strengths, weaknesses, opportunities, and threats. The research method used is a survey method by making direct observations of tourist sites and the distribution of questionnaires to the public and tourists. The data in the analysis uses qualitative descriptive research and SWOT analysis. The results showed the tourism potential in Lilibooi Village is very diverse, supported by the socio-cultural Lilibooi community. This tourism potential attracts many tourists to various places in Ambon city. Community perception shows respondents agree to develop ecotourism activities. People are willing to participate in the development of tourist attractions. They argue that if Lilibooi Village becomes a tourist village, they will get job opportunities and business opportunities through various activities such as selling at tourist sites. Swot analysis results show that the strength factor exceeds weakness, and the opportunity factor is greater than the threat. Hence, the results of the quadrant analysis show the position of ecotourism development is in quadrant I. If the development position is in quadrant 1, then the aggressive strategy (SO) is used. This position describes managing to deal with various threats but still having the strength to take advantage of opportunities to overcome weaknesses.

Abstract

Development of the leather tanning industry in the village of Banyakan, Piyungan, Bantul had a negative impact on the environment. The industrial waste from the leather tanning plant mixed with Cr metal enters the Opak River and is distributed to various places. River water is used as irrigation water which carries heavy metals that result in the accumulation of soil and plants, as well as another biota. The purpose of this study was to determine the profile and level of chromium accumulation in plants along the Opak River. The study was conducted at 6 stations in 6 different districts consisting of samples of irrigation water, sediment, stem roots, leaves, and rice plants. Heavy metal analysis on the sample was carried out using the AAS (Atomic Absorption Spectrophotometry) method. The results of the analysis of heavy metal concentrations that are distributed to the environment show that the plants that are the highest are 2,470 ppm, then sediment is 1,161 ppm, and irrigation water is 0.235 ppm. The highest accumulation of heavy metal Cr in the planting section of rice was consecutively in the grain > leaves > roots > stems. Results of the analysis of the BCF value of rice plant were categorized as a moderate accumulator plant, while the analysis of the TF value of rice plant was categorized as a phytoextraction plant. Health risk analysis HQ > 1, which means that rice from all stations is hazardous to health. Rice and water samples exceeded the established quality standard threshold, except for sediment which was still at a critical level.
