Abstract

The batik industry produces liquid waste from the coloring, washing and rinsing processes. This study was aimed to analyze the quality of Banten batik effluent before and after treatment. The processing is carried out using an experimental method with a batch system by coagulation using alum and adsorption using Bayah's natural zeolite by performing 3 variations of coagulant mass and adsorbent for the dye test parameters, TDS and TSS. The results of the test before treatment were the results for dyes of 344 TCU, TDS 620 mg/L, and TSS 218.5 mg/L. Based on the coagulation treatment using alum, the most efficient coagulant results were obtained to reduce the levels of dyestuffs and TDS, namely by using alum coagulant as much as 1500 mg/L which resulted in 96.6 TCU and 330.0 mg/L respectively, then to reduce TSS levels obtained an efficient coagulant that is 500 mg/L with a yield of 10 mg/L. The adsorption treatment using Bayah natural zeolite can reduce the levels of TDS and TSS with the most efficient results using an adsorbent of 150 g/L obtained for TDS 189.3 mg/L and TSS 13.3 mg/L. So based on the results of processing using coagulation and adsorption methods, it is hoped that the batik industry can apply it in processing the liquid waste produced.

Abstract

The increasing population in Indonesia is directly proportional to the growth of new settlements. In line with this, the growth of waste volume in Indonesia is closely related to the growth of its population. The level of welfare and lifestyle in Indonesia has resulted in a significant increase in waste generation, especially in urban areas. Jatihandap is one of the areas in Mandalajati Subdistrict, Bandung City that increases the influence of waste generation by each people and wants to improve the quality of its waste services to reduce these impacts. One way that can be done to measure the willingness of citizens to improve waste services is to measure the Contingent Valuation Method. Contingent Valuation Method (CVM) Based on the results of this study, WTP values were 138 people from 153 samples selected. The estimated WTP (EWTP) is Rp. 12,971 and the total WTP (TWTP) is Rp. 80,385,000 / month. Based on multiple linear regression analysis, the WTP value of Jatihandap Urban Village is influenced by the amount of garbage contributions and gender equality from the results of the questionnaire that has been done.

Abstract

In order to achieve the national target of decarbonization by 2030, Palm oil mills (POM) can contribute to reducing CO2 emissions generated from their production activities. The CO2 emitted from POM is currently discharged into the environment without further treatment. As a result, the amount of CO2 in the atmosphere will rise, increasing global warming. This study proposes an approach of utilizing CO2 as a density agent in separation fluid formulation. The formulated fluid is then used to separate palm shells and kernels in the claybath. The solubility of CO2 in water occurs physically and is dependent on temperature and partial CO2 gas in the air. Monoethanolamine (MEA) was used as an absorbent to ensure the full interaction of CO2 with water. The chemisorption method is selected to dissolution CO2 into aqueous MEA. The mass ratios of MEA were varied by 10, 20, 30, 40, 50 % w/w. The achieved appropriate densities of formulated fluid were 1,11, 1,14, dan 1,17 g/cm3 at mass ratios of MEA:H2O is 30, 40, dan 50% w/w, respectively. All achieved densities fall between palm shells and kernels densities. Furthermore, the formulated fluid can be used as separation fluid in claybath for separating palm shells and kernels. In addition to the proposed idea of utilizing CO2  and, at the same time, reducing CO2 emission from POM.

Abstract

Administratively, Gampong Beurawe is one of the villages in Kuta Alam District, Banda Aceh City. The Department of Social Affairs is in charge of collecting data and providing assistance to people in need of social welfare services. Data collection is done manually in the form of archives and files, this causes inefficiencies in space, security, time and costs. The Social Service has difficulties in conveying information on the Family Hope Program (PKH) which includes data on poor households, education data and health data, to the wider community and related parties, causing data information to be unclear. So we need an automatic data collection system to help collect data on the hopeful family program in Gampong Beurawe, Kuta Alam District. In the geographic information system itself, there are two important elements, namely Geographical Data which is used as a reference for attribute data. The design of the map that will be displayed in this application uses map info and google maps. This PKH acceptance mapping information system in Beurawe Village, Kuta Alam District, Banda Aceh City is to assist the Social Service, especially the social assistance and security department in the storage and delivery of information data (PKH) so that it can provide clear information about the program. Data information system in the form of maps, graphs and tables.
