Abstract

This research has been carried out to produce adsorbent from Lapindo mud through various activation process, to adsorb nickel from nickel sulfate solution. Several investigations were performed in this research such as characterization of Lapindo mud before and after activation, effect of physical, chemical and chemico-physical activation to Si/Al ratio and determine the most effective method to produce adsorbent with high adsorption rate. Lapindo mud in this research was prepared through several methods such as without activation, calcination at 500 °C for 3 hours, chemical activation with 6 N HCl under reflux for 6 hours, chemical activation with 6 N NaOH under reflux for 6 hours, chemical activation with 6 N HCl under reflux followed by calcination process and the last treatment is chemical activation with 6 N NaOH under reflux followed by calcination process. The object of this research is the Lapindo mud adsorbent ability to adsorb Ni from NiSO4 solution. While activation methods and nickel concentration in this become independent variable. The reduction of nickel concentration efficiency is determined by the nickel concentration before and after adsorption process. The Si/Al ratio of Lapindo mud before activation process was 3.01 and it increase as the mud is activated. The highest Si/Al ratio was found at activation using HCl which is 7.85. Chemical activation using NaOH was found to be the best method to create the adsorbent with adsorption capacity 98.3%.

Abstract

To overcome the waste problem, especially plastic waste , environmental concerned scientists from various disciplines have conducted various research and actions. Catalytic pyrolysis processes was chosen as an alternative method to recycle plastic waste. The purpose of this experiment was to determine the effect of natural zeolit catalyst on the pyrolysis process with oxygen-free conditions to obtain maximum hydrocarbon compounds (gasoline fraction in C5-C9). The process of pyrolysis was conducted in 3.5 dm3 unstirred stainless steel semi-batch reactor. This process operated at atmospheric pressure with nitrogen injection. Plastic waste that used in this particular paper was 50 grams of polypropylene (PP). In pyrolysis process, natural zeolite catalysts was added 2,5 gram (5% weight of natural zeolite per weight of plastic waste samples), 5 gram (10% ), and 10 gram (20%). Temperature of pyrolysis was 450°C and were maintained until 30 minutes. Steam that produced from pyrolisis was condensed and analysed by gas chromatography–mass spectrometry (GC-MS) to determine yield of hydrocarbons produced. From the analysis of GC-MS, liquid products of pyrolysis contained lots of aromatic hydrocarbons. The optimal amount of catalyst that produce liquid with hydrocarbon compound that has the quality of gasoline was 10 gram (20%) with ≤C9 composition as 29,16% n-paraffin, 9,22% cycloparaffin, and 61,64% aromatics.

Abstract

The purpose of writing this article is to examine how the incumbent wives are involved in the 2020 Regional Head Election amid a pandemic as part of launching their political dynasty. Even if you look at the current Coronavirus, it is feared that the moment of the 2020 Regional Head Election could increase the spread and transmission of the Coronavirus. However, on the other hand, if the 2020 Regional Head Election is continuously postponed, many regions will not have a legitimate leader. The approach of this research is descriptive qualitative, while to obtain data, the author uses secondary data from journals, news, and other relevant sources. Meanwhile, to dissect this case, the writer uses Anne Philips' theory of women's political representation, Schumpeter's concept of procedural democracy, and political dynasties. The analysis process begins with data collection, data reduction, data presentation, and conclusion drawing. The result shows that the implementation of the 2020 Regional head Election during the Corona period, which was attended by prospective leaders of the incumbent's wives, became a moment to increase the role of women in politics and part of the political dynasty.

Abstract

Domestic wastewater treatment using Biological Aerated Filter (BAF) method based on bioball is a technological innovation that combines biological and physical processes to improve effluent quality. This study studied the use of a Biological Aerated Filter (BAF) modified with bioball media and variations in residence time to improve waste treatment efficiency and ensure effluent quality by established standards. The study consisted of four stages: preparation, seeding and acclimatization, use of Biological Aerated Filter (BAF), and analysis of the results. The prepared waste samples are domestic liquid waste from shopping centers that have known sample parameters as influential. Seeding and acclimatization are carried out in BAF reactors. Waste was treated through BAF with variable residence time, then analyzed by testing procedures based on \SNI 6989.72: 2009. The results showed that the bioball media in the BAF reactor were more effective than without media, showing a decrease in TDS (92% in 6 hours), TSS (86%), and an increase in COD and BOD efficiency. Effluent pH results are constant at 6-7 as per environmental standards. Obtaining higher process efficiency required a combination of wastewater treatment methods.

Abstract

Limbah cair merupakan salah permasalahan pada pusat perbelanjaan di Kota Malang. Tujuan program ini adalah memberikan solusi alternatif pengolahan limbah cair di salah satu pusat perbelanjaan di Kota Malang. Berdasarkan hasil pengolahan limbah cair secara elektrokoagulasi diperoleh hasil bahwa air limbah domestik Mall Dinoyo yang diolah dengan metode elektrokoagulasi memiliki kandungan COD sebesar 65 mg/L, kandungan BOD sebesar 0,66 mg/L, kandungan TSS sebesar 222 mg/L, kandungan minyak 1,28 mg/L, dan pH sebesar 6,3. Air limbah hasil pengolahan secara elektrokoagulasi sudah memenuhi parameter standard mutu air limbah domestik terutama pada parameter pH, COD, BOD, dan kadar minyak. Namun hasil pengolahan limbah cair secara elektrokoagulasi belum memenuhi parameter TSS. Hasil tersebut juga cukup memuaskan untuk diterapkan di pusat pengolahan limbah cair domestik seperti limbah cair dari pusat perbelanjaan. Perlu pengembangan inovasi lebih lanjut untuk menurunkan kadar TSS pada limbah cair domestik seperti penggabungan metode elektrokoagulasi dengan absorpsi menggunakan karbon aktif.
