BACKGROUND: It is known the effectiveness of a venturi aerator, deposition with a sand filter magnet and ion exchange in one unit to reduce Fe content, total dissolved solid (TDS) and saltiness (CL content) in clean water, and the ability of ion exchange to reduce CL content is known. AIM: This study aims to analyze the effectiveness of venturi aerator, magnetic sedimentation, filtration, and ion exchange in one unit against Fe, TDS, and CL well water. METHODS: The method used is a quasi-experimental method using aeration with a venturi system, deposition with magnets, filtration, and ion exchange. The population in this study was all water containing Fe and CL in the Darul Kamal sub-district, Aceh Besar. The sample in this study is part of the population following research needs. RESULTS: The results showed an effect of a venturi aerator, deposition with magnets, filtering sea sand, anion, and cation resins in one unit to decrease Fe content and did not affect decreasing TDS content and Salinity. Moreover, a venturi aerator has an effect, deposition with magnets, filtering sea sand, anion, and cation resins in one unit on the decrease in Fe content, TDS, and salinity at deposition time of 24 h. Venturi aerator’s effect on Fe reduction does not affect TDS and CL of well water. There is an effect of venturi aerator and precipitation with magnets, in one unit on Fe reduction, and does not affect TDS and CL of well water. There is an effect of venturi aerator, precipitation with magnets, filtration in one unit on Fe reduction, no effect on TDS, and CL of well water. CONCLUSION: This tool effectively reduces Fe content and effectively reduces Fe, TDS, and salinity at a 24 h deposition time.

A combined system of ion exchange (IX) and advanced biophysical treatment of a recirculating regenerant was tested for nitrate removal from groundwater with minimal brine discharge and chloride addition to the product water. Using well water containing 21.5 ± 1.4 mg NO3−-N/L, optimal IX operation was found at a service cycle of 500 bed volumes (BV). Product water nitrate concentrations (7.4 ± 1.4 mg/L as N) met regulations while minimizing both Cl− addition to the treated water (1.03 meq Cl− added per meq NO3−-N removed) and waste brine production (0.2% of the water volume treated). The total organic carbon in the product water was slightly higher (1.5 ± 0.5 vs. 1.3 ± 0.4 mg/L) than the well water and before disinfection the bacterial count was 10–700 cfu/ml. Brine used to regenerate the IX columns was treated first in a sequential batch reactor (SBR) for biological denitrification followed by ozonation for polishing. The SBR was operated at 8 hour cycles and achieved complete nitrate removal. An ozone dose of 3 to 5 mg/L brine allowed for efficient recycling of the denitrified regenerant by removing suspended solids by foam fractionation. In spite of the low brine blow-down, DOC in the recycled regenerant brine after a year of continuous operation was maintained at relatively low levels of 61.0 ± 11.6 mg/L.

SINTESIS DAN KARAKTERISTIK TiO2 DAN SiO2 SERTA APLIKASINYA TERHADAP KADAR Fe DALAM AIR SUMURABSTRAK Air merupakan kebutuhan yang terpenting dalam kehidupan manusia. Air berperan banyak dalam berbagai kegiatan manusia oleh karena itu kandungan yang ada di air harus bermanfaat bagi manusia. Banyak kandungan yang terdapat di air yang sangat bermanfaat, tetapi bayak juga kandungan air yang mungkin tidak bermanfaat bahkan bahaya jika digunakan oleh manusia, salah satunya yaitu kandungan logam berat terutama Fe (besi).  Sehingga tujuan pada penelitian ini untuk mengetahui penurunan kadar Fe (besi) dalam air sumur yang di lakukan dengan fotokimia dengan TiO2 dan SiO2 serta dapat mengidentifikasi karakteristik dari TiO2 dan SiO2. Sampel yang digunakan yaitu air sumur 300 m dibagi menjadi tiga masing-masing 100 ml dengan perlakuan yang berbeda. Pada sampel 100 ml pertama tidak diberikan perlakuan dan juga penambahan. Sampel 100 ml kedua diperlakukan dengan penambahan SiO2 dan pengadukan selama 1 jam, dan untuk sampel 100 ml ketiga diperlakukan dengan penambahan TiO2 dan pengadukan selama 1 jam. Ketiga sampel dengan perlakuan yang berbeda tersebut di analisis dengan menggunakan AAS (Atomic Absorption Spectroscopy) di Laboratorium Kimia Universitas Negeri Semarang. Hasil penelitian Analisis menggunakan AAS (Atomic Absorption Spectroscopy) menunjukkan hasil kadar Fe meningkat pada saat penambahan SiO2 dan TiO2 terhadap sampel yang tidak mendapatkan perlakuan tambahan. kadar Fe pada sampel yang tanpa penambahan sebanyak 0,206 mg/L, kemudian kadar Fe pada sampel yang ditambahkan SiO2 sebenyak 0,225 mg/L, dan kadar Fe pada sampel dengan penambahan TiO2 sebanyak 0,214 mg/L. Hal ini dikarenakan bentuk TiO2 dan SiO2 berupa suspensi. Kelemahan sistem suspensi ini adalah pemisahan partikel TiO2 memerlukan waktu yang lama dan biaya yang sangat mahal,serta daya tembus sinar sinar UV yang terbatas karena absorbsi yang kuat oleh TiO2 (efek bayangan) dan spesies organik terlarut. Kata Kunci: air sumur, TiO2, SiO2, Logam besi (Fe).   SYNTHESIS AND CHARACTERISATION OF TiO2 AND SiO2 APPLICATION TOWARD LEVELS OF Fe IN THE WELL WATER ABSTRACTWater is the most important need in human life. Also, water has many contributions in many human activities. Therefore, the existing content in the water must be beneficial for human. However, material contained in water may be beneficial yet dangerous for human as well, for instance heavy metals content, especially Fe (iron). The main objective of this study is to determine decreasing levels of Fe (iron) in the well water that is done by photochemical reaction using TiO2 and SiO2, and identify the characteristics of TiO2 and SiO2. Samples of well water used is 300 ml divided into three part, and every part of 100 ml water will be given different treatment. First 100 mL sample is not given any treatment and addition. Second 100 mL samples treated with the addition of SiO2 and stirring for an hour, and the third sample of 100 mL is treated with the addition of TiO2 and stirring for an hour. All of three samples with different treatments are analyzed using AAS (Atomic Absorption Spectroscopy) in the Chemistry Laboratory Semarang State University. The research result of analysis using AAS (Atomic Absorption Spectroscopy) shows Fe content increased as the addition of SiO2 and TiO2 in the samples than the sample without any additional treatment. Fe content in the sample without addition is 0.206 mg/L, while Fe content in the sample with addition of SiO2 is 0.225 mg/L, and Fe content in the sample with the addition of TiO2 is 0.214 mg/L. This caused by the form of TiO2 and SiO2 is a suspension. The weakness of this suspension system is the TiO2 particle separation takes a long time, very expensive, and also limited UV rays penetrating power because of the strong absorption by TiO2 (shadow effect) and may dissolved organic species. Keywords: well water, TiO2, SiO2, metals iron (Fe).

Air tanah merupakan andalan sumber mata air bagi masyarakat pada umumnya, beberapa sumber air tanah sering dijumpai air yang masih terkandung Fe, hal tersebut berdampak buruk bagi kesehatan oleh karena itu perlu dilakukan penuruan kadar Fe pada air sebelum digunakan. Beberapa metode yang umum dilakukan untuk menghilangkan kandungan Fe pada air adalah dengan cara koagulasi oleh tawas. Penelitian ini akan memodelkan sebuah persamaan matematika yang dapat mengkuantifikasi penurunan kadar Fe pada setiap fungsi kosentrasi tawas yang ditambahkan. Model matematika pada penelitian menggunakan penurunan rumus dari kesetimbangan masa. Dari hasil perbandingan data percobaan dengan data perhitungan didapat konstanta penurunan Fe (kF) pada fungsi konsentrasi tawas sebesar 1.8/mg tawas dan nilai konstanta R2 sebesar 0.935, dari data tersebut maka model matematika yang dibuat dapat mewakili fenomena proses penurunan Fe di lapangan.In general groundwater is relied as source water but somtimes we found precense of Fe in some of groundwater products that could harm our health due to its toxicity, therefore it is necessary to reduce Fe content as pretreatment process. Some common methods to reduce Fe content in water are coagulation by alum. This study will build a mathematical equation to quantify the reduction of Fe content in function of alum concentration. In this study the equations were derive from mass balance equation. By comparing the experimental data with calculated data, we obtained kF (The constant of consuming Fe) = 1.8 / mg alum and for R2 constant we obtained  0.935, from these result we conclude our derived equation can represent the phenomenon of alum-Fe reduction phenomena in the field.

Deep Subseafloor

&lt;p&gt;The deep subseafloor biosphere represents one of the Earth&amp;#8217;s largest, but also least understood ecosystems with diverse species and mostly uncharacterized microbial communities. International Ocean Discovery Program (IODP) Expedition 370 (Temperature Limit of the Deep Biosphere off Muroto) established Site C0023 down to 1180 mbsf in the Nankai Trough off Japan to explore the upper temperature limit of microbial life in the deep sedimentary biosphere [1]. Site C0023 is characterized by a complex lithostratigraphic and depositional history with strongly changing sedimentation rates. Volcanic ash layers are ubiquitous in all lithological units. However, the highest abundance of ash layers could be observed between 400 and 700 mbsf. Previous studies have shown that volcanic ashes represent hotspots for microbial life [2] and are commonly characterized by high Fe(III) and Mn(IV) contents [3]. Onboard measurements show a release of dissolved Fe in the depth interval associated with the highest abundance of ash layers [1]. Therefore, we hypothesized that the release is related to microbial Fe reduction fueled by the mineralogy of the volcanic ash. In order to identify the source and reaction pathway of the liberated Fe, we applied sequential extractions of differently reactive Fe oxide pools on mud rock and ash layer samples as well as stable iron isotope (&amp;#948;&lt;sup&gt;56&lt;/sup&gt;Fe) analyses on pore-water and solid-phase samples. Microbial Fe reduction leads to Fe isotope fractionation with an enrichment of light isotopes in the released Fe and a respective enrichment of heavy isotopes in the residual ferric substrate. Therefore, the &amp;#948;&lt;sup&gt;56&lt;/sup&gt;Fe signals of different reactive Fe pools and the pore water are used to identify the pools actually involved in microbial respiration processes. Our results show that the total Fe content in mud rock of Site C0023 is relatively constant at ~4.2 wt%. Reactive Fe oxides represent 25% of the total Fe. The bulk Fe content in the ash layers varies between 1.4 and 6.8 wt%. Surprisingly, most ash samples contain less total Fe (3.35 wt% on average) compared to the surrounding mud rock. Similarly, the contents of the reactive Fe oxides are significantly lower. This indicates that either (1) ash layers do not represent the energy substrate for microbial Fe reduction, or (2) reactive Fe in ash samples has already been used up by microbes. The bulk Fe content in recent volcanic material from an active volcano on the Japanese island arc is ~4.4 wt% [4]. The higher Fe content in fresh volcanic material compared to ash samples at Site C0023 might suggest that reactive Fe in ash layers is already reduced. Alternatively, the dissolved Fe release might be related to microbial reduction of structural Fe(III) in smectite promoting the smectite-to-illite transition, which has previously been proposed for Site C0023 [5].&lt;/p&gt;&lt;p&gt;References:&lt;br&gt;[1] Heuer, V.B. et al., 2017.

The dug well water quality in community settlements needs assessment to ensure its quality. The water has to meet the required physical, chemical, and bacteriological standards. This initial research aimed to determine the dug well water quality in Kampung Ujung, Komodo District, Labuan Bajo City, WestManggarai Regency in September 2019. The research method was used survey and laboratory. The two dug well was taken used a purposive sampling technique. The test parameters include temperature, turbidity, pH, smell, Total Suspended Solid (TSS), sulfate, Total Dissolved Solid (TDS), nitrate, nitrite, Total Hardness, Dissolved Oxygen (DO), nitrogen ammonia, total coliforms, and Escherichia coli. The analysis physically, chemically, and biologically of two dug well water samples were had done examined. The result showed that the parameters of TDS, nitrate, nitrite, E. coli, and DO exceed the Class I Water Quality Standard. The research concluded that the quality of both dug well water in the Kampung Ujung Labuan Bajo area was not suitable for use as material raw drinking water. Furthermore, the government should provide other water sources such as the addition of storage tanks for raw water, so that people do not entirely depend on dug well water.

First Year Seminar

When students self-regulate their learning, those using more active strategies demonstrate greater learning than those using passive strategies. The article examines whether teaching active study strategies in a first-year seminar can improve test performance in another course. Using a quasi-experimental approach in two studies, 18 students enrolled in a first-year seminar course received study instruction and selected another course to use these methods. Eighteen control students in a first-year seminar course did not receive study strategy instruction. Results show that when the study-strategy students were required to study for Test 2 using active strategies, they improved more than control students. In Study 2, when study-strategy students were not required to study actively for Test 3, they no longer performed better. This suggest requiring students to study actively improves performance, but research needs to examine how to encourage students to continue studying actively.
