PEMBUATAN DISPENSER DESTILASI AIR LAUT SEBAGAI SARANA SUMBER AIR TAWAR UNTUK DAERAH PESISIR PANTAI
Authors: Koswara Engkos , Nasim Nasim 
Published: December 2021

Kebutuhan air nasional saat ini terkonsentrasi di Pulau Jawa dan Bali, dengan tujuan penggunaannya terutama untuk air minum, rumah tangga, perkotaan, industri, pertanian, dan lainnya. Dari data neraca air tahun 2003 dapat dilihat bahwa kebutuhan air pada musim kemarau di Pulau Jawa dan Bali yang sebesar 38,4 miliar meter kubik, hanya terpenuhi sekitar 25,3 miliar kubik atau hanya sekitar 66 persen. Defisit ini diperkirakan akan semakin tinggi pada tahun 2020, dimana jumlah penduduk dan aktifitas perekonomian meningkat secara signifikan. (Direktorat Pengairan dan Irigasi Bappenas, 2006).
Tanpa terkecuali daerah pesisir pantai juga sangat membutuhkan air bersih. Karena posisinya yang berada dengan laut, sangat mungkin terjadi intrusi air laut sehingga sumber air tawar akan terpengaruh oleh air laut. Oleh karena itu, daerah pesisir pantai sangat membutuhkan air tawar.
Dalam penelitian ini akan dikaji bagaimana membuat Dispenser Destilasi Air Laut sederhana yang dapat dimiliki oleh masing ? masing rumah. Diharapkan dengan cara ini, tiap warga mempunyai fasilitas untuk penyedia air bersih.

Proyek Kereta Cepat Jakarta Bandung merupakan mega proyek kereta cepat pertama di Indonesia. Kondisi tanah terdapat batu cadas yang keras, alat yang sudah tua dengan pemakaian yang terus menerus menyebabkan mesin mati tiba – tiba dan jenis tanah yang menjadi lengket bila bertemu dengan air yang dapat memperlambat proses pengeboran tanah. Berbagai cara pekerjaan pengeboran tanah dilakukan oleh kontraktor, salah satunya menggunakan alat RCD pada pier P 238. Tujuan dari karya ilmiah ini menganalisis produktivitaspengeboran tanah dengan menggunakan alat RCD. Langkah pengeboran dimulai dari pembersihan lapangan dan pembuatan dua buah kolam. Untuk mempermudah pengeboran tiang bor digunakanlah casing. Tinggi casing yang digunakan 4 m dan 6 m. Setelah itu melakukan pengeboran dengan tekanan air 0,2 Kg/cm2 atau dengan kecepatan aliran 7,5 cm/detik sehingga air akan keluar bersama dengan material lumpur melalui pipa di tengah alat bor . Hasil endapan lumpur (padatan) akan dibuang menggunakan truck sedangkan cairan akan dimasukan kembali kedalam lubang bor. Pruduktivitas alat bergantung pada empat faktor yaitu volume pekerjaan, waktu siklus, efisiensi alat dan kapasitas peoduksi. Pada pier 238 memiliki 8 borepile dengan diameter 1,25 meter dan kedalaman 90 meter dengan rata – rata produktivitas sebesar 2,851 m/jam.

Published: December 2021

Objective: To evaluate the accuracy of different intraocular lens (IOL) power calculation formulas and develop prognostic nomograms to predict the risk of postoperative refractive error in primary angle-closure glaucoma (PACG) patients.Methods: A total of 111 eyes with PACG underwent goniosynechialysis combined with phacoemulsification and IOL implantation were included. SRK/T, Barrett II, Hoffer Q, and Kane formulas were used to predict postoperative refraction. Prediction error (PE) and absolute predictive error (APE) produced by the four formulas were calculated and compared. An APE &gt;0.50 D was defined as the event. Binary logistic regression analysis and prognostic nomogram models were conducted to investigate reliable predictors associated with postoperative refraction.Results: The Kane (−0.06 D) and Barrett II (−0.07 D) formulas had mean prediction error close to zero (p = 0.44, p = 0.41, respectively). The Hoffer Q and SRK/T produced significantly myopic outcomes (p = 0.003, p = 0.013, respectively). The percentage of eyes within ± 0.5 D was 49.5% (55/111), 44.1% (49/111), 43.2% (48/111), and 49.5% (54/111), for the Kane, Barrett II, Hoffer Q, and SRK/T formula, respectively. Nomogram showed that AL had the greatest impact on the refractive outcomes, indicating a shorter preoperative AL is associated with a greater probability of refractive error event. The area under the receiver operator curve (AUC) of the nomogram for the Kane, Barrett II, Hoffer Q, and SRK/T was 0.690, 0.701, 0.708, and 0.676, respectively.Conclusions: The Kane and Barrett II formulas were comparable, and they outperformed Hoffer Q and SRK/T in the total eyes with PACG receiving cataract surgery combined with goniosynechialysis. The developed nomogram models can effectively predict the occurrence of postoperative refractive error events.

Published: December 2021

Objective: To preliminarily explore the safety and effectiveness of transpedal lymphangiography (TL) with high-dose ethiodized oil application (&gt;20 ml) in the treatment of high-output postoperative chylothorax.Methods: From 1 July 2020 to 1 July 2021, a total of 7 patients with high-flow postoperative chylothorax (&gt; 1,000 ml/d) were retrospectively reviewed in a single center. Clinical data, including surgery types, technical and treatment success of TL, and adverse events of TL, were collected and analyzed.Results: Seven patients (5 cases of non-small cell lung cancer; 2 cases of esophageal carcinoma) with a median age of 62 years (range: 30–70 years) occurred postoperative chylothorax after tumor resection with mediastinal lymphadenectomy. All patients received conservative treatment including total parenteral nutrition and somatostatin administration for a median of 20 days (range: 15–31 days) that failed to cure the chylothorax, so TL was performed as a salvage. Before TL, the median daily chyle output was 1,500 ml/day (range: 1,100–2,000 ml/day). The technical success rate of TL was 100% (7/7), with the median volume of ethiodized oil of 27.6 ml (range: 21.2–30.0 ml) injected in TL. Ruptured thoracic duct was identified in 5 patients (5/7, 71%) in fluoroscopy and chest CT after TL. The treatment success rate of TL was 86% (6/7). In 6 patients, the thoracic drainage was removed after a median of 7 days (range: 4–13 days) from TL performance. No adverse event of TL was reported.Conclusion: Transpedal lymphangiography with high-dose ethiodized oil application (&gt;20 ml) is a feasible, safe, and effective modality for the treatment of high-flow (&gt; 1,000 ml/day) postoperative chylothorax.

Published: December 2021

Background: Sicca syndrome represents a heterogeneous group of conditions, such as Sjögren syndrome, causing xerophthalmiaand xerostomia. This study characterizes in depth patients with Sicca syndrome and evaluates salivary gland ultrasound (SGUS).Methods: Principal component analysis and hierarchical clustering of clinical parameters, such as ESSPRI, ESSDAI and laboratory data, were performed on all referrals for assessment of Sicca symptoms between October 2018 and March 2021. SGUS and labial gland biopsies were compared across groups.Results: A total of 583 patients were assessed. Objective dryness was confirmed in 73% of the patients. Cluster analysis identified 3 groups with post-hoc analysis confirming distinct phenotypes: Somatic Group (283/583; 49%) with more frequent symptoms but limited objective dryness; Dry Without Autoimmune Features (DAFneg, 206/584; 35%), and Dry With Autoimmune Features (DAFpos, 94/584;16%). DAFpos patients had highest autoantibody titers (anti-SSA(Ro) 240 vs. 3.6 vs. 3.8; p &lt; 0.001), most extra-glandular manifestations (p &lt; 0.001), and highest median SGUS Score (DAFpos: 8 [IQR 4–10] vs. SG: 2 [1–4] vs. DAFneg 4 [2–5]; p &lt; 0.001). No tangible correlation with primary Sjögren syndrome criteria was observed.Discussion: SGUS score correlated with a subset of patients with Sjögren syndrome, identified in the DAFpos cluster. This study highlights heterogeneity within sicca and, indeed, Sjögren syndrome, highlighting the need for further studies.

Published: December 2021

Mutations in the ATP1A3 gene encoding the α3 subunit of Na+/K+-ATPase are associated with different neurological manifestations that may be elicited by febrile episodes. A recently described phenotype, linked to the p.Arg756Cys mutation, is clinically characterized by Relapsing Encephalopathy with Cerebellar Ataxia (RECA). In our case, a diagnosis of RECA has been established, and despite an alternative, reasonable cause had been already identified.We describe the case of a child with two recurrent episodes, 2 years apart, of hypotonia and ataxia. In both episodes, a laboratory-confirmed influenza virus infection suggested the diagnosis of influenza-associated encephalopathy. After the second episode, a search for genetic mutations was performed, and ATP1A3 mutation associated to RECA was found. After both episodes, the child was discharged after partial improvement of neurological conditions.The diagnosis of encephalopathy in children is often challenging. A genetic predisposition to neurological decompensation should be suspected in case of recurrent episodes, even if an alternative diagnosis has been established. Indeed, febrile infections may only represent the trigger of neurological involvement. In these patients, the knowledge of a genetic predisposing factors may help in the prevention of neurological episodes by the prompt use of anti-pyrectics and preventive measures as appropriate vaccination.

Background: To estimate the incidence of Acute Rheumatic Fever (ARF) in Tuscany, a region of Central Italy, evaluating the epidemiological impact of the new diagnostic guidelines, and to analyse our outcomes in the context of the Italian overview.Methods: A multicenter and retrospective study was conducted involving children &lt;18 years old living in Tuscany and diagnosed in the period between 2010 and 2019. Two groups were established based on the new diagnostic criteria: High-Risk (HR) group patients, n = 29 and Low-Risk group patients, n = 96.Results: ARF annual incidence ranged from 0.91 to 7.33 out of 100,000 children in the analyzed period, with peak of incidence registered in 2019. The application of HR criteria led to an increase of ARF diagnosis of 30%. Among the overall cohort joint involvement was the most represented criteria (68%), followed by carditis (58%). High prevalence of subclinical carditis was observed (59%).Conclusions: Tuscany should be considered an HR geographic area and HR criteria should be used for ARF diagnosis in this region.

Published: December 2021

The pyrochlore manganate In2Mn2O7 is a very promising ferromagnetic semiconductor material, which has a good application prospect in spin transport due to its very low electron effective mass, high Curie temperature, and structural stability. In this paper, In2Mn2O7 with pyrochlore structure was successfully prepared by high temperature and high pressure combined with the sol–gel method, and the in situ high-pressure X-ray diffraction experiment was carried out on it. The results showed that the structure of In2Mn2O7 was very stable in the pressure range of 0–29.0 GPa, and its bulk modulus was given. This lays a foundation for the application of In2Mn2O7 in extreme environments.

Published: December 2021

Background: While most previous studies regarding patients with chronic low back pain (CLBP) mainly focused on pain, disability, psychological damage, and intervention measures, the effect of CLBP on personal space remains unclear. The study aimed to assess the personal space of patients with CLBP and healthy controls, explored the differences between the two groups, and examined whether pain, dysfunction, anxiety, and depression affected the personal space regulation.Methods: The cross-sectional study recruited 24 patients with CLBP and 24 healthy controls at Shanghai Shangti Orthopedic Hospital and Shanghai University of Sport, Shanghai, China, from December 2018 to January 2019. A stop-distance paradigm was applied to measure the comfortable and uncomfortable distance under four conditions. A self-rating anxiety scale (SAS) and a self-rating depression scale (SDS) were used to examine the anxiety and depression levels of all participants. The pain intensity and dysfunction in the CLBP group were evaluated by the numeric rating scale and Roland-Morris questionnaire (RMDQ), respectively.Results: When approaching another individual or when being approached, the interpersonal distance under all the conditions in the CLBP group significantly differed from that in the healthy control group with larger space distances (p &lt; 0.01). Gender had a significant main effect on the regulation of personal space in patients with CLBP (p &lt; 0.05). The average pain intensity, scores on RMDQ, SAS, and SDS had a significant positive correlation with the interpersonal distance under the Same or Opposite Gender condition (p &lt; 0.05).Conclusion: People with CLBP show an atypical personal space behavior and indeed have a greater interpersonal distance to strangers. The higher the pain intensity, dysfunction, anxiety, and depression, the greater the interpersonal distance in patients with CLBP. In the future, the effect and underlying neural mechanisms of pain and negative emotions on social withdrawal in patients should be examined.

Introduction: Close contacts have become a potential threat to the spread of coronavirus disease 2019 (COVID-19). The purpose of this study was to understand the epidemiological characteristics of close contacts of confirmed or suspected cases of COVID-19 in the surrounding cities of Chengdu, China, so as to provide a basis for the management strategy of close contacts.Methods: Close contacts were determined through epidemiological investigation of indicated cases, and relevant information was entered in the “Close Contact Information Management System.” Retrospective data of close contacts from January 22 to May 1, 2020 were collected and organized. Meanwhile, the contact mode, isolation mode, and medical outcome of close contacts were descriptively analyzed.Results: A total of 986 close contacts were effectively traced, with an average age of (36.69 ± 16.86) years old, who were mainly distributed in cities of eastern Chengdu. The frequency of contact was mainly occasional contact, 80.42% of them were relatives and public transportation personnel. Besides, the time of tracking close contacts and feedback was (10.64 ± 5.52) and (7.19 ± 6.11) days, respectively. A total of seven close contacts were converted to confirmed cases.Conclusions: Close contacts of COVID-19 have a risk of invisible infection. Early control of close contacts may be helpful to control the epidemic of COVID-19.

Background: Biofilms, when formed on the surfaces of water pipes, can be responsible for a wide range of water quality and operational problems. We sought to assess the bacterial and free-living protozoa (FLP) diversity, in relation to the presence of Legionnaire's disease-causing bacteria Legionella pneumophila (L. pneumophila) in 45 biofilms of hot water distribution system pipes of apartment buildings in Riga, the capital city of Latvia.Results: 16S rRNA amplicon sequencing (metataxonomics) revealed that each biofilm contained 224 rather evenly distributed bacterial genera and that most common and most abundant were two genera, completely opposites in terms of their oxygen requirements: the obligately anaerobic Thermodesulfovibrio and the strictly aerobic Phenylobacterium. Water temperature and north-south axis (i.e., different primary water sources) displayed the most significant effect on the inter-sample variations, allowing us to re-construct three sub-networks (modules) of co-occurring genera, one involving (potentially FLP-derived) Legionella spp. Pangenome-based functional profile predictions suggested that all three may be dominated by pathways related to the development and maintenance of biofilms, including quorum sensing and nutrient transport, as well as the utilization of various energy sources, such as carbon and nitrogen. In our 18S rRNA amplicon sequencing data, potential hosts of L. pneumophila were detected in 11 out of 12 biofilm samples analyzed, however, in many cases, their relative abundance was very low (&lt;1%). By validating our findings using culture-based methods, we detected L. pneumophila (serogroups 2, 3, 6 and 9) in nine (20%) biofilms, whereas FLP (mostly Acanthamoeba, Vahlkampfidae and Vermamoeba spp.) were present in six (~13%) biofilms. In two biofilms, L. pneumophila and its potential hosts were detected simultaneously, using culture-based methods.Conclusions: Overall, our study sheds light on the community diversity of hot water biofilms and predicts how several environmental factors, such as water temperature and source might shape it.
Electrical Properties of Two Types of Membrane Component Used in Taste Sensors

Published: December 2021

The lipid phosphoric acid di-n-decyl ester (PADE) has played an important role in the development of taste sensors. As previously reported, however, the concentration of PADE and pH of the solution affected the dissociation of H+, which made the measurement results less accurate and stable. In addition, PADE caused deterioration in the response to bitterness because PADE created the acidic environment in the membrane. To solve these problems, our past study tried to replace the PADE with a completely dissociated substance called tetrakis [3,5-bis (trifluoromethyl) phenyl] borate sodium salt dehydrate (TFPB) as lipid. To find out whether the two substances can be effectively replaced, it is necessary to perform an in-depth study on the properties of the two membranes themselves. In this study, we fabricated two types of membrane electrodes, based on PADE or TFPB, respectively, using 2-nitrophenyl octyl ether (NPOE) as a plasticizer. We measured the selectivity to cations such as Cs+, K+, Na+ and Li+, and also the membrane impedance of the membranes comprising PADE or TFPB of the different concentrations. As a result, we found that any concentration of PADE membranes always had low ion selectivity, while the ion selectivity of TFPB membranes was concentration-dependent, showing increasing ion selectivity with the TFPB concentrations. The ion selectivity order was Cs+>K+>Na+>Li+. The hydration of ions was considered to participate in this phenomenon. In addition, the membrane impedance decreased with increasing PADE and TFPB concentrations, while the magnitudes differed, implying that there is a difference in the dissociation of the two substances. The obtained results will contribute to the development of novel receptive membranes of taste sensors.
