Abstract

Environmentally friendly agriculture and food health are needed to support tourism in Bali. Meanwhile, it is alleged that agricultural products do not meet the requirements, especially the quality that does not meet consumer requirements. This research refers to the Udayana University Research Master Plan, a leading field of food security. Food Security Research Roadmap, with the aim of producing appropriate technology. The research products can be implemented in activities to increase production, quality of horticultural crops and food health to support tourism. The research method was through testing the productivity and quality of tomato plants through the addition of organic fertilizers, mineral fertilizers, chemical fertilizers, and their combination. The highest production was obtained from the treatment of P6 = mineral plus fertilizer (5 tons of hill lime + 5 tons of organic fertilizer products organic fertilizer product simantri + 100 kg urea + 100 kg phonska) per ha, can increase production (34.46%). Treatment of mineral fertilization (P2) =mineral fertilizer 5 tons of hill limestone, contains the highest vitamin C (286.14 mg/kg), P2 is also able to neutralize heavy metals Cu and Mo, increase calcium content, increase shelf life, thicken tomato skin walls which Calcium sticks to tomato skin.

Abstract

Rivers play an important role in life, but they are highly polluted by increased activities in the surrounding. For example, Ciliwung River is experiencing heavy metal pollution which has affected aquatic organisms including the pleco fish widely used by local communities as food ingredients such as dumplings, dimsum, and otak-otak. This element’s content rises in pleco fish flesh yearly and the accumulation after entering the human body interferes with health. Even though the usage of citric acid-containing lime reduces heavy metals, currently, no information explains the fruit’s effectiveness on metal content in pleco fish. Therefore, this research aims to prove the effectiveness of lime solution on pleco fish flesh quality. It was conducted by soaking the fish flesh with control and the lime solution at different concentrations, namely 0, 50, 75, and 100% for 10 and 30 minutes. Proximate analysis was performed followed by metal and mineral content testing through the XRF method. Based on the results, soaking the sample object with a higher concentration of lime and at a longer time caused a decrease in ash content, while water, protein, and fat increased. After soaking, Pb and Hg content had chelation in each treatment but still exceeded the SNI threshold value, while Sn was in accordance with the SNI. The content of macrominerals (K, Cl, Mg, and P) and microminerals (Cu, Zn, and Se) became different.

Abstract

Beef is one of the animal protein sources needed by the body to meet nutritional requirements. Consequently, fresh beef (whole or milled) is one of the highest-demanded comestibles on the market. Some meat kiosks in Yogyakarta traditional markets are also in service of milling whole meat. However, reports are stating that some kiosks are neglecting aspects concerning halal. One of those aspects is separating tools used to process beef and pork. Reports said that kiosk owners fail to meet that essential requirement causing Muslims to be at risk of consuming contaminated beef without their knowledge. Hence, this study aims to examine whether fresh and ground beef obtained from Pasar Pathuk and Pasar Kranggan, Kota Yogyakarta, is free from pork contamination. The examination was carried out using Polymerase Chain Reaction (PCR) on 14 samples of seven fresh and seven ground beef obtained from both markets. DNA isolation from all samples was done using FavorGen® FavorPrepTM Tissue Genomic DNA Extraction Mini Kit. Isolated DNA was further examined by PCR analysis using P14 and MTCB primers. Results showed that P14 primers could amplify the PRE-1 gene (481 bp) designed as a pork molecular marker only on positive control (fresh pork); meanwhile, MTCB primers could amplify the cytochrome b gene (1141 bp) designed as a mammal molecular marker on all samples involved in this research. Based on the results, we concluded that both fresh and ground beef sold in Pasar Pathuk and Pasar Kranggan, Yogyakarta are not contaminated by pork DNA.

Abstract

The use of Tagetes Erecta Linn flowers as a repellent against the Aedes Aegypti L mosquito (Diptera: culidae) has been carried out. Extraction of 570 grams of Tagetes flower samples was carried out by maceration using methanol to produce 44 grams of thick green extract. Phytochemical test results showed the methanol extract of Tagetes flower samples were positive for flavonoids. Compound fractionation was carried out and obtained 3 fractions, namely water fraction, acetone fraction and n-hexane. The results of the phytochemical test showed that the n-hexane fraction was negative for flavonoids, while the water and acetone fractions were positive for flavonoids. The total yield of flavonoids in the water and acetone fractions was 8293.2692 mg/100 grams and 4964.1148 mg/100 grams, respectively. The water fraction of Tagetes flower extract was tested for active compounds using the GC-MS instrument. Test the effectiveness of the repellent effectiveness of Tagetes flower compounds, the lowest was 5% at 5 hours at 9.35% and the highest was 20% at 1 hour at 60.58%.
