Penggunaan Limbah Ban Dalam Sepeda Motor Dalam Campuran Aspal AC-WC

Aspal merupakan bahan yang banyak digunakan dalam pembangunan jalan. Penggunaan bahan aspal semakin tinggi, maka bahan aspal yang digunakan semakin mahal dan terbatas. penelitian dilakukan sebagai upaya menghemat bahan aspal dengan penambahan limbah ban dalam, dengan tujuan untuk mengetahui pengaruh penambahan limbah ban dalam terhadap bahan aspal AC-WC. Penelitian Yang Digunakan Adalah Marshall Test Yang Dilakukan Di Laboratorium. kemudian diperoleh hasil perhitungan yaitu marshall quotient. Karakteristik campuran perkerasan AC-WC meliputi kepadatan (density), rongga pada mineral agregat (VMA), rongga terisi aspal (VFA), rongga dalam campuran (VIM), stabilitas, kelelehan marshall (flow), dan Marshall Quotient (MQ). Hasil penelitian dari 3 variasi campuran limbah ban dalam yang digunakan dengan nilai variasi 0%, 0,2%, 0,4%, dan 0,5% untuk nilai variasi yang memiliki stabilitas tertinggi terdapat pada variasi 0,2% dengan nilai stabilitas sebesar 1547,19 kg, dengan nilai VMA 19,70%, nilai VFA79,23%, nilai VIM 4,10%, nilai flow 2,10 mm, dan nilai MQ sebesar 728,07 kg/mm.

Improvement of electrical properties of CMC-PVA doped with various contents of LiNO3 as an application for hybrid polymer electrolytes

The present work was carried out with the development of hybrid polymer electrolytes (HPEs) by using carboxymethyl cellulose (CMC)–polyvinyl alcohol (PVA) doped with different contents of lithium nitrate (LiNO3) for the determination of their structural and conduction properties. The structural analysis was conducted by using Fourier transform infra-red spectroscopy and showed the interaction between the blend host polymer and ionic dopant, which formed via the coordinating site of CMC-PVA and Li+-NO3−. The complexes of CMC-PVA doped LiNO3 led to an increment in ionic conductivity, as observed by electrical impedance spectroscopy, and the sample containing 20 wt% LiNO3 obtained the highest ionic conductivity of 3.54 × 10−3 S cm−1 at room temperature. The ionic conductivity at different temperatures (from 303 K to 343 K) was measured and found to obey the Arrhenius rule. The activation energies of the HPEs were computed based on the Arrhenius equation and were inversely proportional to the ionic conductivity. The highest ionic conducting sample was fabricated into an electrical double layer capacitor (EDLC). Cyclic voltammetry (CV) was used to study the electrochemical performance of the EDLC. A high value of Cs was obtained at 2 mVs−1 due to the utilization of ions in the vacant sites of the electrode material

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Effects of Processing Technique on Physical and Organoleptic Properties of Whole Meal Bread

Whole meal bread made up from whole grains mostly consumed due to health purpose. The aim of this study was to determine the effect of processing technique on physical (colour, moisture content, pore size, texture and specific volume) and organoleptic properties of whole meal bread. Three treatments which B1, B2 and B3 of whole meal bread were prepared which represent the processing technique straight dough, sponge and dough, and sourdough, respectively. Whole meal bread between B1 and B2 with B3 showed significant (p < 0.05) increased in density (276.58, 270.35, 647.84 g/cmᶾ), hardness (747.16, 747.16, 2425.75 g/cmᶾ) and chewiness (495.71, 519.98, 2843.73 g) respectively. Variations were observed for crumb (internal) and crust (external) colour from 33.77 to 39.63 (L-value), 3.08 to 9.80 (a-value) and 25.38 to 10.82 (b-value), 23.65 to 27.94 (L-value), 2.27 to 2.95 (a-value), 9.26 to 13.11 (b-value) respectively. Hence, straight dough method produced whole meal bread with higher value of specific volume (3.58 cmᶾ/g), moisture content (24.66 %), lightness of crumb (23.65) and chewiness (495.71 g). Thus, results showed that straight dough method was the most efficient and acceptable method for bread baking process in order to get the good physical and organoleptic properties of whole meal bread

Regenerated Cellulose Products for Agricultural and Their Potential: A Review

Cellulose is one of the most abundant natural polymers with excellent biocompatibility, non-toxicity, flexibility, and renewable source. Regenerated cellulose (RC) products result from the dissolution-regeneration process risen from solvent and anti-solvent reagents, respectively. The regeneration process changes the cellulose chain conformation from cellulose I to cellulose II, leads the structure to have more amorphous regions with improved crystallinity, and inclines towards extensive modification on the RC products such as hydrogel, aerogel, cryogel, xerogel, fibers, membrane, and thin film. Recently, RC products are accentuated to be used in the agriculture field to develop future sustainable agriculture as alternatives to conventional agriculture systems. However, different solvent types and production techniques have great influences on the end properties of RC products. Besides, the fabrication of RC products from solely RC lacks excellent mechanical characteristics. Thus, the flexibility of RC has allowed it to be homogenously blended with other materials to enhance the final products’ properties. This review will summarize the properties and preparation of potential RC-based products that reflect its application to replace soil the plantation medium, govern the release of the fertilizer, provide protection on crops and act as biosensors

Hydrogel Application in Urban Farming: Potentials and Limitations—A Review

Urban agriculture plays a vital role in ensuring the self-sufficiency of a great variety of fresh vegetables and nutrients. It promotes a sustainable food system as well as reducing the dependency on imports for the growing population. Urban farming has made it possible for agriculture practices to be implemented anywhere at any time in a sophisticated way. Hydrogel has been introduced in urban agriculture in the past few decades. However, the application of hydrogel in urban agriculture is still being explored in terms of hydrogel types, structure, physical and chemical properties, change due to external factors, and its suitability for different plant species. This review discusses the potentials and limitations of hydrogel in different application conditions. We present the state of knowledge on hydrogel production and crosslinking methods, hydrogel characteristics, water absorption and release mechanisms of hydrogel, hydrogel advantages and limitations, and current and future applications in urban farming
