Abstract

Concrete's drawback is its low tensile strength and heavy weight, which may exceed 2400 kg/m3. The significance of self-weight in building construction is essential, particularly when dealing with seismic loads. The larger the inertial force from the weight of the structure itself, the greater the inertial force from the weight of the building itself, therefore lightweight concrete can provide an opportunity to lower its own weight with a smaller unit weight of 1850 kg/m3. Fly ash was employed as a substitute for cement in this investigation, while pumice was used as a substitute for coarse aggregate. The goal of this research was to establish the unit weight, compressive strength, and workability/slump value of concrete. In this investigation, 30% of the fly ash was utilized. Pumice is determined at 0%, 5%, 10%, and 15% of the weight of coarse aggregate. The SN sample has the highest slump value of 8.8. However, the slump value continued to fall with the addition of pumice. The use of larger pumice stone results in   a reduction in the volume weight of concrete up to 1845 kg/m3, permitting it to be classified as lightweight concrete. Pumice has been demonstrated to diminish strength by 11% on average for every 5% replacement

Abstract

Utilization of waste materials as building materials is a solution to reduce waste materials that exist in nature.Fly ash as a waste product from coal combustion contains silica which can be used to increase the compressivestrength of concrete/mortar. Paving Block as a building material made of mortar composition can be increasedits compressive strength by substituting some cement material with fly ash. Fine aggregate material in the formof sand can also be substituted with natural limestone waste material. In this study, paving blocks were madeusing limestone as a substitute for fine aggregate and fly ash as a cement substitute. The ratio of materials formaking paving blocks is 1: 4. For variations of substitution materials, fly ash is used as a cement substitution.The variation of fly ash is 20% and while the limestone waste is used variations of 0%, 10%, 20%, 30% and 40%.The compressive strength test was carried out at the age of 7 days, 14 days, and 28 days. The results of the studyof compressive strength at the age of 7 days obtained a value of 12.24 MPa at a natural limestone substitutionconcentration of 20.7%. For the age of 14 days the compressive strength value is 15.27 MPa with an optimumconcentration of 20.1% at the concentration of natural limestone, while at the age of 28 days the compressivestrength value is 17.11 MPa, with the optimum concentration of natural limestone material being 20. .15%. Theincrease in compressive strength from the optimum mixture to the normal mixture was 28.93%. Based on SNI 03-0691-1996 the paving blocks produced in this study include Quality B.

Abstract

Beton merupakan bahan bangunan populer yang diakui kekuatan dan daya tahannya. Para peneliti telah mengeksplorasi penggunaan superplasticizer dan gel C-S-H untuk meningkatkan kualitas beton . Superplasticizer adalah bahan tambahan kimia yang dapat ditambahkan ke campuran beton untuk meningkatkan fluiditas sekaligus menjaga kekuatan. Hal ini memudahkan pemasangan dan meningkatkan kemampuan kerja beton. Selain itu, menambahkan gel C-S-H ke beton dapat meningkatkan kinerja jangka panjang dan meminimalkan retak. Formasi gel C-S-H pada kekuatan dan daya tahan beton diselidiki secara cermat dalam studi ini dengan melakukan pengujian foto SEM EDS. Pemindaian Mikroskop Elektron-Spektroskopi Sinar-X Dispersi Energi adalah alat analisis yang kuat untuk menentukan komposisi unsur dan bentuk bahan berskala nano. Ini menyelidiki permukaan material dengan berkas elektron terfokus dan menghasilkan sinyal yang dapat digunakan untuk mengidentifikasi dan memetakan distribusi komponen yang ada. Hasil Uji SEM-EDS menunjukkan Unsur senyawa Ca, Al dan Si mendominasi. Rasio Oksida SiO2/CaO yang tinggi pada sampel cenderung memiliki kuat tekan yang lebih tinggi. Sebaliknya, material dengan rasio SiO2/CaO yang lebih rendah menunjukkan kuat tekan yang lebih rendah.

Abstract

Introduction: Hypoglycemia is a medical emergency requiring immediate intervention as it can lead to fatalities. One of the initial treatments for hypoglycemia out of hospital settings is the administration of sweet food and drinks. This research aims to analyze the difference in blood glucose level increase between respondents given date juice and those given sugarcane juice.  Methods: A quasi-experimental two-group pretest-posttest design was conducted in March 2024, involving 92 students divided into 2 groups (Intervention Group: 46; Control Group: 46) recruited through purposive sampling. Both groups were asked to fast for 14 hours, followed by blood glucose measurement (pretest), and then given date juice (intervention group) and sugarcane juice (control group). Blood glucose post-test was conducted at 15 and 30 minutes after intervention with a glucometer, and data were analyzed using ANOVA (α≤0.05).  Results: The study indicated an increase in blood glucose levels after date juice intake at 15 minutes with a mean of 129.83 mg/dl (p=0.000), followed by a decrease in mean blood glucose from 15 to 30 minutes by 21.7. There was an increase in blood glucose levels after sugarcane juice intake at 15 minutes with a mean of 131.17 mg/dl, followed by a decrease in mean blood glucose from 15 to 30 minutes by 19.8. Statistically, there was no difference in blood glucose increase between the two groups at both 15 minutes (p=0.633) and 30 minutes (p=0.347). Conclusion: Date juice and sugarcane juice similarly increase blood glucose levels and can be used as out-of-hospital therapies for conscious hypoglycemic patients.

Abstract

ABSTRAKPenelitian ini mencoba memanfaatkan campuran limbah fly ash dan SEC (Electrocoagulation of Sludge) menjadi material yang berguna untuk digunakan sebagai bahan penyusun paving block. Selama ini, limbah SEC dari pabrik tekstil hanya dikumpulkan sebagai bahan yang tidak berguna, sehingga memanfaatkan penggunaan material limbah ini menjadi lebih penting dalam rangka pengurangan limbah padat pada lingkungan sekitar. Untuk meningkatkan kuat tekan paving block, campuran fly ash, yang merupakan bahan limbah industri yang tidak dimanfaatkan. Komposisi campuran fly ash pada nilai 20% sedang komposisi variasi SEC sebesar 0%, 5%, 10%, 15%, 20%, dan 25%. Pada masing-masing kondisi dibuat 9 benda uji dengan pembagian masing-masing 3 benda uji untuk pengujian 7 hari, 28 hari dan 56 hari. Hasil penelitian menunjukkan bahwa penambahan konsentrasi SEC makin tinggi akan mengurangi kuat tekan dan mutu paving block. Namun untuk variasi limbah SEC sebesar 5% masih dapat digunakan untuk campuran dengan target mutu pavingblock B. Penurunan nilai kuat tekan dikarenakan adanya pengaruh unsur karbon (C) dalam limbah SEC. Secara visual, Benda uji dengan kandungan SEC tinggi akan terlihat basah, dan mengalami proses pengeringan yang lama, hal ini dikarenakan SEC memiliki sifat menangkap air, dan sulit menguapkan air.Kata kunci: sludge, limbah tekstil, elektrokoagulasi, fly ash, pavingblock ABSTRACTThis research tries to utilize a mixture of fly ash waste and SEC (Electrocoagulation of Sludge) into a useful material to be used as a paving block material. So far, SEC waste from textile factories has only been collected as useless material, so making use of this waste material has become more important in order to reduce solid waste in the surrounding environment. To increase the compressive strength of paving blocks, mix fly ash, which is an unused industrial waste material. The composition of the fly ash mixture is 20%, while the SEC variation composition is 0%, 5%, 10%, 15%, 20% and 25%. In each condition, 9 test objects were made, divided into 3 test objects each for 7 days, 28 days and 56 days testing. The research results show that adding a higher SEC concentration will reduce the compressive strength and quality of the paving block. However, a 5% variation in SEC waste can still be used for a mixture with a paving block quality target of B. The decrease in compressive strength is due to the influence of the carbon element (C) in SEC waste. Visually, test objects with a high SEC content will appear wet, and undergo a long drying process, this is because SEC has the property of capturing water, and is difficult to evaporate water.Keywords: sludge, textile waste, electrocoagulation, fly ash, paving block
