Abstract

Propanol gas is an alcohol compound classified as a volatile organic compound (VOC). This gas can be classified as air pollution with a harmful impact on human health. There is an urgent need to minimize the health impact by mitigating propanol gas concentration. There is limited information about propanol gas measurement. Therefore, developing a propanol gas measurement device with high sensitivity and selectivity is necessary. Hence, this study developed a propanol gas concentration measurement system based on a bare quartz crystal microbalance. This crystal was placed inside an experimental chamber and exposed to propanol gas. The crystal frequency shift was measured using a frequency counter. The results show that the propanol gas concentration is linearly correlated to the frequency shift resulting in the crystal with a regression coefficient of R2 > 0.75). The system can measure propanol concentrations <1 μg.L-1 with a sensitivity of 5 Hz.mg.L-1. It can be concluded that a gravimetry-based measurement system using a quartz crystal microbalance has the potential to measure the concentration of propanol gas.

Abstract

Fishery in estuary make changes function of mangrove land and decreased, so that it affect water quality. This study aims to determine mangrove density and relation with the quality of wonorejo estuary waters. The method uses purposive random sampling and line plot method with a 10x10 meter plot to determine the criteria for mangrove density and water quality tests based on physic-chemical parameters and then correlated to test the effect. The results of the water quality analysis at the Wonorejo estuary with the optimum value at station 5 have an average parameter value of temperature (29°C), brightness (22 cm), current speed (0.083 m/s), TSS (55 mg/L), pH (7.36), salinity (5.5), DO (1.709 mg/L), COD (42.4 mg/L), nitrate (0.18 mg/L), and phosphate (1.045 mg/L). The criteria for mangrove density at each station include low density, medium density, and high dense density. Physic-chemical parameters related to mangrove density are temperature, brightness, salinity, and COD. Estuarine waters based on physic-chemical parameters, namely 40.3% salinity, 33.7% COD, 30.9% brightness, 30.8% temperature, 14% nitrate, 11.4% TSS, 8.1% current velocity, 1 .3% DO, and 0.1% phosphate affected by mangrove density.

Abstract

Buduran River, Sidoarjo Regency, is one of the rivers in Sidoarjo City, which has various functions. The primary function of the Buduran River at the moment is to supply raw material water for one of the PDAM Delta Tirta Sidoarjo, namely the Drinking Water Treatment Plant (IPAM) branch in Siwalanpanji. For this reason, efforts are needed to maintain and monitor river quality using the Qual2Kw method. QUAL2Kw method begins with the determination of 3 segments. Furthermore, an analysis of hydraulic data, water quality, and pollutant sources was carried out, determining the scenarios used, running the QUAL2Kw program, and calculating the carrying capacity of pollution loads. River water quality parameters include pH, BOD, COD, TSS, Phosphate, and Nitrate. Applying the QUAL2Kw method in evaluating the Buduran River with three scenarios according to existing conditions, initial conditions according to quality standards, and trial & error with maximum pollutant load. The capacity value is determined based on the calculation of the difference in pollutant load in scenario three and scenario 2. The result is that the Buduran River is classified as a polluted river, and the negative (-) pollutant load capacity indicates that management is necessary to reduce pollutant loads.

Abstract

River water treatment uses a Sequencing Batch Reactor (SBR) with cassava peel adsorbents, meranti wood powder, and PAC. After going through the Sequencing Batch Reactor, (SBR), it will give disinfection to reduce the levels of E. Coli and total coliform in the water. It is expected to be able to set aside levels of turbidity, color, TDS, taste, odor, total coliform, E.Coli, nitrate, nitrite, hardness, and organic matter (KMnO4). The river water to be treated comes from the coagulation-flocculation process. Making variations of HRT and adsorbent. The hydraulic retention time variations compared were 6, 9, and 12 hours. There are 3 reactors with 1 control reactor, which includes a control reactor without adsorbent and one with PAC adsorbent. The conditions chosen at the reaction stage are aerobic. The removal efficiency of the color parameter is 8.4%, the total coliform parameter is 94.6%, the parameter e.coli 95.2%, the nitrate parameter is 52.6%, the nitrite parameter is 14.3%, and the organic matter parameter is 7.8%. At the same time, the parameters have increased by 2%. The best HRT in reducing pollutant levels in this study was 12 hours HRT for the SBR reactor with cassava peel adsorbent sowing placement, 6 hours HRT for the SBR reactor with meranti wood powder adsorbent sowing placement, and 6 hours HRT for the SBR reactor with top placement PAC adsorbent. The best effectiveness of the Sequencing Batch Reactor (SBR) in treating Kebon Agung River water is by adding meranti wood powder adsorbent by placing sprinklers

Abstract

Insana Barat Subdistrict is an area in North Central Timor Regency which is vulnerable to the dry season every year and experiences a water deficit. To reduce the risk of drought, community preparedness needs to be improved through the provision of water to deal with drought. Several efforts have been made by the government and the community to cope with drought, including the construction of dams, distribution of clean water fiber, and the existence of cropping patterns in agriculture. This study aims to determine the capacity of the people of Insana Barat  District in dealing with drought. The role of the community becomes very important because in fact the community and local organizations are the key in disaster risk reduction initiatives. The method used in this research is quantitative with a survey in Insana Barat  District with 335 respondents spread over each village. Determination of respondents in this study was done randomly. The analysis technique used is scoring and capacity calculation using the asset pentagon on the variables of human assets, social assets, natural assets, physical assets and financial/financial assets. The results showed that the people in Usapinonot Village, Unini Village, Letneo Village, Banae Village, Nifunenas Village, Subun Tualele Village, Subun Bestobe Village belonged to low capacity, Subun Village, Lapeom Village, Atmen Village and South Letneo Village were classified as medium capacity. and Oabikasi Village is included in the high classification.

Abstract

contains COD, TSS, PO4, and Total-N pollutants that can contaminate water bodies if the treatment process is not carried out first. In this study, the NPK fertilizer industry waste treatment was carried out using sequencing batch reactors (SBR) and granular activated carbon (GAC) by adding the coagulation-flocculation process as a pre-treatment so that wastewater can meet the established quality standards. In this study, the reactors were operated at HRT 12, 24, and 48 hours using a GAC mass concentration of 0.5, 1, and 2 g/L. The results show the highest reduction of COD parameters by 67%, TSS by 82%, PO4 by 45%, Total-N by 76%, optimal HRT by 48 hours, and an optimal GAC mass concentration of 2 g/L. The aeration rate is operated at 14 L/min, with a PAC concentration of 3 g/L being optimal.
