Abstract

All minerals contained in drinking water, including Pb and Fe, shall be inaccordance with Regulation of the Minister of Health of the Republic of Indonesia No. 492/MENKES/PER/IV/2010, which shall not exceed 0.01 mg/l for Pb and 0.3 mg/l for Fe. The provision is also required against Bottled Drinking Water (AMDK). If the content is excessive can disrupt and endanger health.Based on Permenkes Number 492/2010, the researchers have conducted the test of Pb and Fe content of 7 (seven) brands of Bottled Drinking Water (AMDK) local production of the western-southern coastal area of Aceh province. In the study, researchers used descriptive methods based on laboratory test results. The sampling technique is done by purposive sampling, in which each brand is taken 3 (three) drinking water sample in glass packaging 220-230 ml from different market/location. The results of observation, researchers found 7 brands of Drinking Water In Packaging (AMDK). The test is repeated 2 times. So the total is 42 test samples. The results showed that from 42 test samples gave excellent results on Pb content, which of the seven brands of AMDK tested did not show the Pb content to the lowest limit that can be detected by Atomic Absorption Spectrosphotometry (SSA), which is 0.002 mg/l. The content of Pb is far below the requirement stipulated in Permenkes Number 492/2010, is not exceeding 0.01 mg/l. While the Fe content of the seven brands of AMDK tested gave varying values, but the content is still very low compared to the Fe content permitted Permenkes No. 492/2010, which does not exceed 0.3 mg/l. Where there are 2 brands of AMDK have Fe content ranging from 0.12 to 0.17 mg/l, while from 5 other brands of AMDK have Fe content ranges from 0.0113 to 0.0941 mg/l. So, from the results obtained it can be concluded that the seven brands of Bottled Drinking Water (AMDK) production area of South West Coast of Aceh is safe for consumption, because it does not cause the impact of Pb and Fe content is still far from the maximum set Permenkes No. 492/2010.Keywords: Pb, Fe, Bottled Drinking Water

Abstract

The concept of supply chain management is a new concept that sees all company activities as an integrated part. In this case the integration of the company in the upstream (upstream) in providing raw materials and integration in the downstream (downstream) in the process of product distribution and marketing. This study aims to analyze the supply chain system of clove commodities in Simeulue Regency which is more effective and efficient so that it can be applied by the community, especially clove farmers. The method used in this research is to use the HOR (House of Risk) method. From the house of risk mapping results, 6 selected risk agents will be used as consideration material in the preparation of mitigation actions, namely: A-7 (Inadequate transportation technique) with an ARP value of 330, A-3 (Lack of experience in finding supply of raw materials) with an ARP value of 288, A-13 (Non-compliance with clove shipping documents) with an ARP value of 276, A-9 (Ineffective communication) with an ARP value of 258, A-11 (Non-compliance with the agreement with the supplier of cloves) by default ARP 189 and A-15 (Failure of price negotiations with producers) with an ARP value of 126.

Abstract

This study aims to identify tannin compounds in the leaves of starfruit (Averrhoa bilimbi L.) and to find out the benefits of starfruit leaves. starfruit leaf extract obtained through starfruit leaves crushed first, then added a solution of methanol and then filtered using filter paper, then extracts of starfruit leaf extract divided into two test tubes, in which one tube is dripped with iron (III) chloride. The results showed that, the color of the wuluh starfruit leaf extract which was originally brownish yellow turned blackish blue. It can be concluded that the starfruit leaves of tannin compounds were identified. Tannin compounds function to bind and precipitate protein. So that in health tannins function to treat diarrhea, treat hemorrhoid, stop inflammation and also can be a natural alternative to cleaning artificial teeth.

Abstract

The improvement of SMEs productivity can be seen from the ability of SMEs to make an effective and efficient production process. The problems issued by the Aceh Traditional Cake Maker SMEs above if viewed in more detail occur in the production process. SMEs do not support many production processes that can be increased to be more effective and efficient. During this time, SMEs Makers of Traditional Acehnese Cake feel there is waste that often occurs. However, Aceh's traditional SMEs makers rarely take measurements. In fact, waste really determines business efficiency and will certainly have an impact on productivity and low business profits. The purpose of this study is to allow waste that occurs with the concept of discussing Lean with the method of mapping the flow of values and reducing this waste so as to be able to increase the productivity of MSMEs Traditional Acehnese Cake Makers. The Lean concept will eliminate waste or non-value added activities from a process at the Aceh Traditional Cake Maker SMEs so that activities along the process flow produce Value. The method used to collect waste is Value Stream Mapping (VSM). The results of this study obtained waste that occurs in the process of making cakes waste of waiting time and waste of transportation that occurs in the work element of mixing dough, waste of defective products that occur in the work element of frying. The improvement offered to reduce waste is the activation of production equipment.

Abstract

This research aimed to determine the optimum concentration of Acetobacter xylinum to produce maximum nata de banana skin. The banana peel was used as a medium with Acetobacter xylinum added with concentrations of 10%, 20%, 30%, 40% of 400 ml of media solution. The results showed that the thickness of nata de banana skin with treatment variation were 0.77cm, 2.09cm, 2.77cm, 2.38cm, yield of 22.6%, 42.3%, 51.4%, 46.4%, and water content 87,6%, 86,6% 85,8% 86,2%. The preferred organoleptic test is at 30% concentration in the form of color, taste and suppleness. The result of research can be concluded that Acetobacter xylinum optimum concentration to produce the maximum of nata de banana skin is 30% for thickness, rendement, moisture content and organoleptic test of nata de banana skin.

Abstract

Quality Control is very important in efforts to minimize the number of defective products. One of them is in small and medium businesses in the Kerudung Micro Small And Medium Enterprises in Sukowati Bungah Village, Gresik District, Gresik Regency. This Micro Small And Medium Enterprises owned by Ms. Hj difficultiawati. The purpose of this research is to analyze the defects of veil products by using the Six Sigma method namely DMAIC (Define, Measure, Analuze, Improve, Control). The results of this study indicate that the company has a total number of disability veils of 225 units consisting of untidy edge trimming, creased fabric, holes in the veil fabric, less neat screen printing, inappropriate colors. In the process of making this veil there is a value of the damage ratio on goods by calculating the upper control limit (UCL) of 134.9761 and the Lower Control Limit (LCL) of 73.6899 and the average damage to the CL veil of 104.3333 currently at level 1 sigma so that improvements need to be made to achieve level 6 sigma. Using the Pareto diagram tool and for quality improvement improvements were made to the veil disability with SIPOC (Supplier, Input, Process, Output, Customer).

Abstract

This study aimed to identify levels of catechins in gambier. The sample used is Gambir taken in the market with differences in terms of color, shape and packaging. Solid Gambir is mashed and added with water until it becomes a paste and then filtered to produce pure gambier extract. Furthermore, it was deposited and dried then crushed and sieved with a size of 60 mesh. Samples were dissolved with ethyl acetate and ethanol in a ratio of 1:10 and then dried and tested for catechin content, tannin content, water solubility and ash content. The results showed that catechin levels in G1 samples were 50.81%, G2 samples were 40.60%, and G3 samples were 30.70% while tannin levels in G1 samples were 11.50, G2 samples were 17.21 and samples G3 of 23.51. The result of the research concluded that there were differences in the amount of catechins in the three study samples. The best catechin levels were found in the G1 sample as much as 50.81%, then the G2 sample as much as 40.60%, and the G3 sample as much as 30.70%. While the tannin content has an inverse amount of concentration than concentrates. The more the amount of katekin in gambier the lower the amount of tannin.
