Abstract

Laundry wastewater is one of the contributors to domestic wastewater since laundry services have been increasing in urban living, especially in big cities. Laundry wastewater may contain phosphate compounds, and the concentration should be reduced before discharge into water bodies. One of the easiest and friendly methods for removing phosphate in laundry wastewater is by using the adsorption process. Adsorption is influenced by the adsorbent material, and fly ash has been implemented as adsorbent due to its high capacity to adsorb pollutants. This study aims to observe the effect of adsorbent height in the column and the effect of flow rate to treat phosphate in laundry wastewater. This study applied Thomas modeling to determine the model for fly ash capacity as adsorbent. The results showed that the highest flow rate, 15 mL/min, and the highest fly ash height 20 cm gave the optimum removal of phosphate, about 98.63-99.22%. Besides, Thomas model obtained the value of the linear regression coefficient of 0.5415.

Abstract

Changes in the coastline are a natural phenomenon that often occurs on various coasts where this event has a further effect in the form of sedimentation and erosion along the coast. As a result of this phenomenon, the coast is said to be dynamic towards the various changes that occur, and one of them is the change in sea surface temperature. The purpose of this research is to find a correlation of changes in sea surface temperature to changes in the existing shoreline on the coast of Ujung Pangkah Gresik in addition to calculating the speed of change of the coastline. The method used is the use of remote sensing technology to analyze sea surface temperature and geographic information systems to analyze changes in coastlines. The results obtained from this study are changes in sea surface temperature statistically affect changes in coastlines with an error rate of 5% at the 20 measured observation points. The model used in sea surface temperature is a linear model with an R-value of 0.783, and the change in the coastline at Ujung Pangkah Gresik is 153 meters per year measured between 2019 and 2020. The conclusion obtained from this study is that the increase in sea surface temperature will affect climate change on the coast and will ultimately affect changes in the coastline.

Abstract

Biscuits are foods made from wheat flour with the addition of other food ingredients. It is made through the process of heating and printing. The characteristics of biscuits are generally determined by their crisp texture. One of its ingredients is Pedada fruit flour (PFF) which has high dietary fiber content. It serves as a complement when added to purple sweet potato (PSP) flour with a high source of anthocyanin and antioxidants. The purpose of this study is to optimize the effect of the proportion between PFF and PSP flour on product quality. The research method used was the Response Surface Methodology (RSM) code. The experimental level values were: +1,414(17.5:100); +1(15:95); 0(10:90); -1(5:85); and -1,414(2.5:80). Furthermore, the research designs between PSP flour to PFF were: (85:5); (95:5); (85:15); (95:15); (90:10); (90:10); (90:10); (90:10); (90:10); (90:2.5); (90:17.5); (80:10); and (100: 10). The data obtained were analyzed using the Expert Design 10.0 analysis. The results showed that the best treatment was in the proportion of PFF to PSP flour having a value of (90:10). This produced biscuits with criteria of: 6.18% of moisture; 2.63% of ash; 0.87% of fat; 3.26% of protein; 2.15% of crude fiber; 1.65% of antioxidant; breaking strength 7.43N; color L*34.0; color a*17.4; and color b*10.8.

Abstract

A magnesium oxide and titanium (II) oxide nanocomposite, MgO/TiO2 was synthesized to improve its surface area thus its adsorption capability may be risen. The synthesis was applying sol-gel method, combining MgO and TiO2 nanoparticles with NaOH becomes a nanocomposite with higher surface area. Characterization using FTIR were carried out. The expectation of using MgO/TiO2 compared with TiO2 and MgO alone is it may react faster on an adsorption trial with remazol turquoise blue dye, and the TiO2 may give its photocatalysis ability to the synthesized material. The FTIR analysis results show that the MgO and TiO2 are successfully combined become MgO/TiO2 nanocomposite. On adsorbing remazol blue, MgO/TiO2’s surface is chemically influenced by the dye’s C=O and amides group.

Abstract

Spirulina platensis is a type of blue - green algae that has a micro-sized spiral shape and lives in marine waters. There are so many benefits of this microalgae, one of which is it can degrade organic pollutants in wastewater. Excessive nitrate and phosphate in the water can cause eutrophication which is indicated by the death of many sea biotas because of phytoplankton bloom. In this research, tofu which high in organic pollutants are used as experimental test media. The microalgae which will be tested is cultivated first to obtain a sufficient amount for research, then the microalgae are acclimatized before being put into an Oxidation Ditch Reactor mixed with tofu waste with a capacity of 250 liters, ran with 60 rpm brush aerator for 7 x 24 hours and also uses natural lighting from sunlight. samples were taken once a day at 12 noon each day. This research has a variety of wastewater: algae that are 1:1. From the results, it can be observed that Spirulina platensis microalgae could reduce maximum phosphate by 33,15 %, from 18,1 mg/L to 12,1 mg/. Furthermore, microalgae also capable of decreasing nitrates by 46,07 from 0,89 mg/L to 0,48 mg/L.

Abstract

In Indonesia, project databases are not well managed, covering hundreds or thousands of cost items and work items from construction projects. This condition becomes more complex when operators are required to integrate between CBS and WBS, which requires extra effort to perform detailed, rush, and accurate grouping. This study attempts to demonstrate the role of data science in managing CBS and WBS through the code system method in the pivot table. The analysis process requires four stages, step 1. data preparation, step 2. item relationship, step 3. code system analysis, and step 4. validation and evaluation. The results showed that the codes applied including A1001-A1003 have CBS and WBS derivatives in a systematic and well-structured manner so that automatically the calculation of the quantity and cost that accompanies each of these items obtains accurate results. This article is expected to provide options for field practitioners to perform data management to be efficient and productive for the continuity of construction projects going forward.
