Abstract

Abstract. Inadequate processing of waste in household areas has resulted in many people throwing the waste anywhere. Waste generation can be minimized by using the composting method. There are many methods of composting organic waste; one of them is the Tong Composter. Tong Composter is a composting method which in the process uses an EM4 bio-activator. Objectives: This research objective is to determine whether the liquid organic fertilizer parameters produced comply with the standard of Ministerial Decree of Agriculture No. 261 of 2019. Method and results: This research using the experimental method with two treatments, EM4 dosage (60 ml and 70 ml) and fermentation time (10 days and 20 days). A dose of EM4 in treatment 1 is 60 ml, and treatment 2 is 70 ml; each treatment was analyzed on the 10th day. For treatment 3 and 4, a dose of EM4 in treatment 3 is 60 ml, and in treatment 4 is 70 ml; each treatment was analyzed on the 20th day. Then from the liquid organic fertilizer produced, several parameters were analyzed at PT. Sucofindo Cibitung, such as Nitrogen, P2O5, and K2O parameter. Meanwhile, the pH will be measured in the Environmental Engineering Laboratory of President University. The laboratory experiment results from pH, Nitrogen, P­2O5, and K2O will be tested using the t-test. With the hypothesis (HO: µ sample ≥ minimum value of macro-nutrient and pH parameter from Ministerial Decree of Agriculture of the Republic of Indonesia Number 261 of 2019). According to the t-test result, the null hypothesis is rejected because Nitrogen, P2O5, and K2O in all parameters are less than 2%. The null hypothesis is accepted for pH because in all parameters is higher than or equal to 4. Conclusion: The t-test result showed that only the pH was complied with the standard, while the Nitrogen, P­2O5, and K2O parameters have not complied with the standard of Ministerial Decree of Agriculture No. 261 of 2019.

Abstract

Waste generation in recent years has been increasing. The main problem is in the lack of environmental awareness. Awareness can be influenced by behavior, knowledge and income. This research wants to find out whether these 3 factors have an influence to the awareness of housewives who manage their household waste that live in residential area partially and fully. Questionnaires using likert scale that have undergone validity and reliability test were distributed online using Google Form to 100 housewives. Data were analyzed using descriptive analysis and Multiple Linear Regression. Results showed that behavior and knowledge have positive significant influence toward awareness while income has no significance towards awareness on the respondents.

Abstract

Due to the data in 2030, the urban growth in developed countries is 83% and developing countries is 53%. Jababeka II Industrial Estate as one of the urban industrialization located at Bekasi Regency. In its development, drainage facilities are one thing that must be considered. Because with its function as a channel that carries runoff water to rivers/lakes/reservoirs to avoid flooding. This study aimed to know the existing condition of the drainage system and the water balances in the form of runoff in Jababeka II Industrial Estate by the simulation of SWMM 5.1.  The method of this research used a quantitative method, and the data collection method used secondary data, including the information from the existing drainage system with precipitation events in 12 years (2009-2020) were obtained from the WTP Jababeka Residential, drainage dimension, and masterplan of Jababeka II. In order to calculate rainfall planned used fifth-year return period based, it’s on the city's classification under study. The probability distribution method uses Log-Pearson III with a planned rainfall of 128.22 mm/d and the highest rainfall intensity of 54 mm. Based on the simulation results, it was found that the Jababeka II Industrial Estate contained puddles in several channels. The peak was at the 3rd hour of the simulation, which were 19 channels. It's influenced by the type of soil that is quickly saturated. The simulation of the existing condition at Jababeka II has the highest runoff at the 2nd hour of simulation, and floods occurred in 19 channels. It’s affected by the impermeable sub-areas. The water balance result is the amount of precipitation 128.22 mm with the intensity is 54mm due to 5 years forecasting, thus producing the outflow is 128.511 mm. Therefore the number of continuity errors of the surface is -0.227%.

Abstract

Changes in land use require consideration of the sustainability of the area. The principle of a triple bottom line in sustainable development must be applied. This research builds a sustainable development model in Bekasi Regency. The secondary data used is from the Central Bureau of Statistics of Bekasi Regency. The variables used are the average of rainfall, the number of population, the number of job seekers, the area of rice field, the area of rice harvest, the production of wetland rice, and the production of field rice as independent variable and GDP as the dependent variable. Consideration of the selection of variables by looking at the economic, social and environmental aspects that are aspects that determine the sustainability of development. Data analysis was done by using multiple linear regression. The results showed that the population, paddy field area, paddy field production have a significant positive effect to PDRB, while the number of job seekers, paddy field area, and paddy field production significantly negatively. The average variable of rainfall has no significant effect to GRDP. Taken together (simultaneously) all the independent variables have a significant effect on GRDP.

Abstract

Abstract. The problem of household waste faced in industrial areas is becoming increasingly urgent, considering that industrial areas are areas that are growing very rapidly. Jababeka Smart Township initiative is one of the efforts to provide services to the community, to improve sustainable living. In waste management, it takes the amount of waste generated to be managed, so that the measurement of household waste generation is the first step needed. Objectives: The objectives of this research are to know the waste generation at Jababeka residential, to know the waste generation of Mekarmukti village, and to analyze the waste generation in Jababeka area.   Method and results: The method of measuring household waste generation used follows SNI 19-3964-1994. The population used in this study were Mekarmukti villagers, both living in housing and outside housing. Purposive sampling method used in find the sample, method of data collection was observation, and descriptive statistics used for data analysis. The result found that the average waste generation from people at Jababeka residential is 0.33 kg/day/person, and out of residential is 0.37 kg/day/person. In Mekarmukti village, center of waste recycle could used to manage the household waste Based on this average waste the potential technology could implemented the solid waste management. Conclusion: The average waste generation in Jababeka residential is 0.33 kg/day/person and outside of residential is 0.37 kg/day/person, and this amount still less than the average waste produced per person per day in Indonesia.
