The use of water spinach plants (Ipomoea aquatica Forsk.) for phytoremediation of hospital waste

Abstract Water spinach (Ipomoea aquatica Forsk.) has the ability to accumulate pollutants so that it can be useful for wastewater treatment processes. The purpose of this study was to determine the phytoremediation technique in hospital wastewater using kale in improving the quality of hospital wastewater and to determine the level of accumulation of Pb and Cr metals in plants. The study used a completely randomized design with four treatments, namely treatment 0 days (without treatment), 2 days, 4 days and 6 days. Parameters include the physical and chemical quality of the waste as well as the content of Pb and Cr in the waste and plants. To determine the effect of phytoremediation on the quality of household waste and metal content, ANOVA analysis and further testing with the BNT test level of 5% were used. Phytoremediation with kale was able to reduce the temperature of the waste on the 4th day of treatment and dissolved oxygen on the 4th treatment and increase the pH. The accumulation of Pb and Cr on each day is different. The highest accumulation of Pb and Cr occurred on day 6, namely 0.1587 mg/L for Pb metal and 0.2167 mg/L for Cr metal. Kale plants are very possible to be used in the phytoremediation process.

This study aims to know the effect of swamp buffalo’s rumen liquid based fodder toward physical and chemical quality of lamb meat. This study used 12 male Kacang goats at age of 10-12 months with weight around 12±1.2 kg. Method used in this study was Completely Randomized Design with 4 treatments repeated for 3 times until it reached 12 units of trials. The treatments consist of: (PS), regular fodder given by breeder (PFCK1) 25% rumen liquid based fodder + 75% PS. (PFCK2), 50% rumen liquid based fodder + 50% PS. (PFCK3) 75% rumen liquid based fodder + 25% PS. Data was statistically analyzed by using variance analysis. Difference between treatments was tested by using Duncan’s New Multiple Range Test. Study results showed that the usage of rumen liquid based fodder of 75% increased protein and lamb fat content (P < 0.05), the lamb meat was physically more tender (P < 0.05). The conclusion is swamp buffalo’s rumen liquid could be used to enhance lamb meat quality.

The method for determining the appropriate time to harvest banana could affect the shelf life and quality of banana fruits during storage. The objectives of this study were to establish the heat unit as harvesting criteria of banana “Mas Kirana” and to evaluate how heat unit affects fruit shelf life and postharvest maturity characteristics. The research was conducted at PTPN VIII Parakansalak Plantation, Sukabumi, West Java, Indonesia, in November 2017 to February 2018. Laboratory analysis was conducted in Postharvest Laboratory, Department of Agronomy and Horticulture IPB in February to April 2018. The experiment was organized in a completely randomized design with a single factor of eight different flower tagging times after anthesis. Each treatment was replicated five times totaling 40 experimental units. The results showed that the different times of anthesis did not affect fruit size, weight per hand, number of fruits per hand and weight per fruit. Different time of anthesis did not affect respiration rate, fruit shelf life, physical and chemical quality. The minimum heat unit of 650ºC degree days can be used as harvesting criteria for banana “Mas Kirana”. The number of day after anthesis was 39 to 43 with fruit shelf life of 12 to 16 days.

Abstract The objective of this work was to evaluate the effect of different compositions of renewable substrates and seasons of the year on the quality of Piptocarpha angustifolia clonal plants. The experiment was carried out in a completely randomized design in a 4x6 factorial arrangement (four seasons x six substrate compositions). The analyzed substrates were: S1, commercial substrate with pine bark and coconut fiber base (CF); S2, carbonized rice husk (CRH); S3, fibrous and grainy CF; S4, 50% CF and 50% CRH; S5, 30% CF and 70% CRH; and S6, 70% CF and 30% CRH. Minicuttings of 8±1 cm were planted in tubes of 110 cm3 and placed in a greenhouse, during the four seasons of the year. The evaluated variables were: survival and number of roots at 70 days; survival and emission of shoots at 100 days; rooting, shoot height, stem diameter, and their ratios; easiness of removal from tubes; aggregation to the substrate; and multiplication rate at 130 days. The highest CRH/CF ratio favored the development of better-quality plants, and S5 was the most adequate substrate. Spring is more favorable to the survival and quality of cuttings, and, together with summer, favors the highest multiplication rates. The S5 substrate has better physical and chemical quality and improves P. angustifolia clonal plants.

The water treatment processes in which microorganisms act are margin filtration, slow filtration and biological activated carbon (CAB) [2]. For this research, a study of permeable concrete with the addition of 2% activated carbon for light traffic paving was performed. The objective of this research is to identify the feasibility of using this concrete so that filtered water can reach at least the basic sanitation networks, with a better quality to be treated. For this, characterizations of the quality of the concrete component materials were made with a novelty, using the fine aggregate (sand). After the characterizations, the permeable concrete traces with mechanical strength of 30MPa were made. Dosing analyzes followed with molding, curing and rupture of concrete specimens. The results of the arithmetic mean of the axial compression of conventional concrete at 28 days were 34.2 MPa and the concrete with the addition of activated carbon was 32.2 MPa, reaching the expectations of strength. Complementary experiments were performed for the quality of the water filtered by the CP's, the pH, the alkalinity and the chlorine content were analyzed. The pH of the conventional concrete found was 7.6 and the concrete with the addition of activated carbon was between 7.2 and 6.8, which may be the best result found

The experiment was conducted to determine the effect of turmeric powder supplementation to the age of sexual maturity, physical, and chemical quality of the first Japanese quail’s (Coturnix japonica) egg. Forty five quails were assigned into a completely randomized design with three treatments (levels of turmeric powder, i.e., 0; 54; and 108 mg/quail/day) and each treatment used 15 quails. Turmeric powder supplementation was conducted before sexual maturity. Feed and drinking water provided ad libitum. Observed egg is an egg that was first produced. Parameters measured were the age of sexual maturity, feed intake, body weight, physical qualities which include: weight of egg, long axis, short axis, weight and thickness of shell, yolk index, Haugh unit, egg shell index. Whereas the observed chemical quality were cholesterol, HDL, LDL, protein, vitamin B12, vitamin A in eggs and egg shell calcium levels. The results showed that administration of turmeric powder can accelerate the age of maturity, increasing the levels of protein, HDL, vitamin A and B12 in eggs, decreasing the cholesterol and LDL content in eggs, but did not affect feed intake, physical quality of eggs and egg shell calcium levels. Based on the results of this study, it can be concluded that supplementation of turmeric powder improve the chemical quality of Japanese quail eggs (Coturnix japonica), so it is good for the development of quail embryos as well as for consumption.How to CiteSaraswati, T.
