Abstract

Uncontrolled accumulation of vegetable waste can have a negative impact that will affect various aspects of life, either directly or indirectly. Many studies have used vegetable waste as a raw material for making fertilizers by adding EM4 as a source of decomposing microorganisms. EM4 as a source of microorganisms can be replaced with local microorganisms from a mixture of cabbage waste, cheese whey, molasses, rice bran, and coconut water. For this reason, this study uses vegetable waste, namely cabbage with variations in fermentation time and the ratio of cabbage waste and whey cheese as a natural decomposer from a mixture of vegetable waste and cheese whey which is processed by fermentation so that it can be used as a source of microorganisms in the manufacture of liquid organic fertilizer (POC). This study aims to study the effect of fermentation time and the effect of the ratio on the process of making natural decomposers from cabbage vegetable waste and cheese whey. This study uses a ratio of 30:70; 20:80; 10:90; 0:100 on a mixture of cheese whey and cabbage vegetable waste (WLs) with fermentation times of 7, 14, and 21 days. From the analysis of nitrogen levels, the highest yield was found at a ratio of WLs 20:80 of 1.54 with a fermentation time of 14 days, while analysis of phosphorus levels obtained the highest results with a ratio of WLs 10:90 of 0.77 at a fermentation time of 21 days. potassium obtained the highest yield with a ratio of WLs 30:70 of 0.41 at 21 days of fermentation. While the results of identification and analysis of the number of microorganisms showed that the manufacture of a natural decomposer solution with a fermentation time of 7 days contained 1 type of isolated lactic acid bacteria, namely Bacillus subtilis, and there were no pathogenic bacteria such as E. coli and salmonella. WL variable. 20:80, which is 15 × 104 colonies/100 mL.

Abstract

Bangil area is a coastal area surrounded by industry. Groundwater ini Bangil Sub-district have poor quality impacted by surrounding conditions. One of the parameters of poor groundwater quality is the total plate count (TPC) value which reaches 151 x 10 colonies/ml with a standart of 1.0 x 102 colonies/ml. TPC value represents the number of microorganism colonies in the water. To reduce TPC value, its necessary to disinfect the microorganism in the water. One method that can be used is the chlorination process. The chlorination process by adding kaporit with kaporit variables 3 ppm, 4 ppm, and 5 ppm with reaction time 10 minutes, 20 minutes, 30 minutes, 40 minutes, and 50 minutes. Output from chlorination prcess will be analyzed for pH, TDS, TSS, turbidity, TPC, and residual Cl-. From the research, the TPC value decreased significantly and the best variable was obtained at a chlorine concentration of 5 ppm, with a reaction time of 50 minutes.

Abstract

The increasing number of migrants in Pandaan District, Pasuruan, has led to a rise in the number of laundry services. However, laundry operations have negative environmental impacts due to the disposal of untreated laundry wastewater into water bodies. Based on initial characteristic tests, the TSS, BOD, and COD in laundry wastewater were found to exceed the quality standards set by the East Java Governor Regulation No. 72 of 2013. This study aims to examine the effects of aeration time and variations in the dimensions of the Soil Mixture Block (SMB) on the treatment of laundry wastewater using the Aeration – Multi Soil Layering (MSL) system, regarding the reduction of TSS, BOD, and COD levels. The aeration times used were 0, 30, 60, 90, and 120 minutes, while the SMB dimensions varied as follows: (4×20×4) cm, (4×20×8) cm, and (4×20×12) cm. The results demonstrated that the Aeration-MSL system was effective in reducing the concentrations of TSS, BOD, and COD. The optimal variation was found with an aeration time of 120 minutes and an SMB dimension of (4×20×12) cm, which resulted in a reduction of TSS by 78%, BOD by 93.79%, and COD by 88%.

Abstract

Planting with a hydroponic system is a technique for cultivating plants without using soil media, but instead using water as a medium for cultivating plants. So that planting with a hydroponic system can use narrow land. So a study was conducted with the aim of applying Liquid Organic Fertilizer (POC) with the Indonesian National Standard (SNI) in a hydroponic planting system by adding POC constituent nutrients to the growth of roots and leaves of mustard greens, by adding a dose POC concentration of 0%, 9%, 12%, and 15% by analyzing samples of 0, 7, 14, 21, 28, 35 days to obtain better growth of pakcoy vegetables. The best growth of pakcoy plant roots was obtained from a concentration of 15%, obtained a length of 18.75 cm. The best growth in leaf width of the oajcoy plant was obtained from a concentration of 0% or without POC, the leaf width was 5.75 cm.

Abstract

Gel organic fertilizer is the result of liquid organic fertilizer that is converted from liquid to gel, which is produced naturally. This gel organic fertilizer is an additional material used to meet the nutrient needs of plants to increase better productivity. The source of gel organic fertilizer is not much different from liquid organic fertilizer. Where the material for making gel organic fertilizer can be obtained from agricultural residues, MSME industries, factory waste that has no selling value such as vegetable waste, cheese whey waste, and molasses. This study aims to determine the effect of variable thickening agents on gel fertilizer from various gel structure modifiers. The treatments are as follows: The fixed variable is the fermentation time of 14 days and the independent variable of gel structure modifiers including tapioca starch, Carbopol 94, and Aquakeeper Hydrogel. The results of this research show that the treatment of free variables has a very significant effect and gives the best results without involving auxiliary media such as heating.

Abstract

Rosella, a plant previously known as a flower, is now one of the plants that is often used as an object of research. Apart from simplicia, rosella is produced as a drink that has health benefits. Rosella production includes tea, jelly candy, instant drinks, and syrup. Roselle syrup production is carried out using process engineering, namely temperature and heating time. The addition of sugar was also intended to see its effect on preserving the syrup. The sugar added is varied at 1; 1.25; and 1.5 kg. In the syrup-making process, citric acid is added to enhance the taste. In this research, the heating temperature was carried out at the boiling temperature, with the heating time varying between 10 minutes, 15 minutes, and 20 minutes. Heating is also carried out at a temperature of 85 °C with a heating time of 30, 40, and 50 minutes. Laboratory analysis of the product is vitamin C analysis. To test consumer acceptance of the product, a hedonic test is carried out, which includes tests on taste, color, and structure (viscosity). The results obtained by this research were a syrup product with the largest vitamin C content, namely 25,251 mg/100 g, at a heating variation of 85 °C with a heating time of 50 minutes. Optimal sugar addition at 1.25 kg
