Abstract

Strawberry (Fragaria, sp) is very popular and delightful fruit in Indonesia. Nowadays Ciwidey County of South Bandung Region has been well known as one of the biggest producer of strawberry in West Java province and as one of tourist destination offers a concept of agrotourism activity where visitors are allowed themselves to pick any ripe strawberry fruit up directly from the plant in the farm. The usage of organophosphate insecticide to increased a quantity of product during harvest and as a pest control materials, it becomes a residue which can jeopardize the consumer’s health. The research is done to observe and to know the contents of the residue of organophosphate insecticide in strawberry farm of the agro-tourism. Samples are obtained directly from 1000 sqm – 5000 sqm strawberry farm for three days in a row. The analysis method used a tool of Chromatography Gas and its extraction used homogenizer with acetone and hexane as a solvent base on Method of Standard Analysis of Pesticide Residue, Commissioner of Pesticide 1997. Insecticide Organophosphate from the group chlorpirifos and profenofos are common use in Ciwidey. Therefore only these two types are targeted for further investigation. The result of research shows on both washed and un-washed strawberry fruit the existence of residue chlorpirifos at 0,027 ppm average in washed fruit and 0,0048 ppm in un-washed fruit while the profenofor residue is 0,0547 ppm in un-washed fruit and 0,029 ppm in washed fruit. The values are still below Maximum Residue Limit (MRL) by Codex Alimentarius. The fruit washing process by submerging can reduce insecticide residue at 40%-60%.

Abstract

At present, attention to the quality of public health is increases. One of the things that highlighted in order to improve the quality of public health is the drinking water aspect. The objects of this research is to implement WHO's new program, entitled Water Safety Plan Program. This program is intended to ensure the quality of drinking water produced appropriate with quality standards and safe for consumption by society, according to health-based targets. Research carried out by measuring and testing the physical parameters of water quality in accordance to Kepmenkes RI nomor 907/MenKes/SK/VII/2002. The measured parameters are temperature, conductivity, and turbidity. Whereas, the tested parameters are Total Dissolved Solid (TDS) and odor. From the results of the measurement and testing, determined the critical point and critical control point of the entire piped water supply system. The critical point is determined from the parameters passed quality standards. By looking at the provision of potable water piping system as a whole, determined which stages that potentially as critical control points. The test results showed that the major critical control point located at the stage of filtration, both for the parameters of turbidity, TDS, or odor, because the next stage of the drinking water supply could not process these parameters again. Critical point in the piped drinking water supply system by Dago Pakar taps located on the parameters of turbidity, with a value that exceeds the quality standard of raw water until the start of the processing stages in the flocculation unit.

Abstract

Livestock waste is one of the sources of organic pollutants in surface and ground water. This entire time, the cattle owners in Dago Atas dispose the cattle manure directly into Cikapundung River without any treatment. Then it needs to be implementing a treatment technology to overcome the negative impact of the wastes disposal and to gain an added-value by recycling the livestock waste into organic fertilizer products. The solid fertilizers were made by mixing the manure with 5% Effective Microorganism 4 (EM4) of the total weight of the manure, while the liquid fertilizers weremade by adding 10% of EM4 into the cattle urine. To ensure that this technology appropriates to be applied, further research is needed in order to investigate the effect of the fertilizer utilization on the plant growth. The fertilizer in this research was implemented on the mustard greens and the lettuce crops. This research was arranged in a completely randomized factorial design with two factors: the first is a combination of the solid fertilizers dose and the second is a combination of the liquid fertilizer dose. The growth variables measured for each crop are the plant height per week, amount of leaves, total fresh weight, consume fresh weight, harvest index, and stem diameter. Based on the ANOVA test was concluded that the solid fertilizer effect on plant height, number of leaves, stem diameter, total weight and consume weight of mustard green. While on the lettuce, solid fertilizer effect on plant height, stem diameter, total weight, and consume weight. The use of liquid fertilizer had no effect on growth of mustard and lettuce. From the Duncan test, found that the best solid fertilizer dose in mustard green and lettuce is 4 kg/m2.

Abstract

Six samples of carrot and potatoes were collected from conventional and organic farms. Organochlorine pesticides (OCPs) residue was analyzed using liquid-liquid extraction. The concentration of OCPs residue together with the consumption pattern were used to calculate the potential risk. Estimated Daily Intake (EDI) of OCPs residue in carrots and potatoes both from conventional and organic farms were below the standard given in SNI 7313:2008 and the Maximum Residue Limit (MRLs) from USEPA . Hazard quotient (HQ) and Hazard Index (HI) as effect analysis were below the unity, thus there may not be a concern for non-carcinogenic effect. Risk analysis on cancer effects indicated that potatoes samples were above the recommended risk by EPA (10-6). In addition, risk of potatoes samples from organic samples was higher compare to that of the conventional farm. Cancer risk analysis of carrot samples were found below the recommended risk by EPA. Cancer risk effect of carrot samples from conventional farm was slightly higher compare to that of the organic farm.

Abstract

A study on soil buffering capacity to cadmium and addition of paddy hay, and the effects on paddy (IR-64 variety) growth and production has conducted in a green house of Environmental Engineering Laboratory of ITB and Bogor Research Center and Development for Food Crop. Latosol soil from Ciparay, South Bandung Regency was used in this research. The aim of the research was to investigate the buffering capacity of the soil to cadmium and the effects of paddy hay addition of 10 tonnes/acre on rice growth and productivity. Statistical method used is group random design with eight treatment combinations and three repetitions. Advanced test was then employed by using Duncan’s Multiple Range Test (DMRT) in 5% level. Treatments given were different concentration levels of cadmium in the water which would be applied to the plants. These concentrations were A0 (0 mg/L), A1 (0,12 mg/L), A2 (0,50 mg/L), and A3 (10 mg/L). Whereas treatment of paddy hay addition were: control (B0) and 40 g in every treated pot (B1). The results showed that latosol soil had a good buffering capacity to cadmium (99,77% without paddy hay addition) and better result with paddy hay addition (99,86%) at 10 mg/L cadmium treatment. Addition of paddy hay with cadmium concentration treatments did not significantly affect the production of IR-64 variety paddy.
