“…Soft soils include clay and silt types. In clay, soil characteristics can be observed directly in the field, which will crack when dry (shrink) and expand in wet conditions [7]. The grain size of silt soil is more significant than clay soil.…”

Generally, the existence of soft soil in Indonesia will be a problem in the construction of highway construction. One factor that influences and needs to be known in road construction is the characteristics of the subgrade where the pavement construction will be placed on it. Poor soil characteristics can cause bumpy road surfaces, cracks, or other road damage. Therefore, before carrying out a soil improvement, it is necessary to know its characteristics through the physical and mechanical properties of the subgrade. This research was conducted in Lubuk Bayas Village, Serdang Bedagai Regency, North Sumatra Province. Tests of physical properties in this study include sieve analysis, water content, specific gravity, plasticity limit test, and liquid limit test. The soil shear strength test and California Bearing Ratio (CBR) test were carried out to test the mechanical properties using a Dynamic Cone Penetrometer (DCP). From the results of testing the physical properties of the soil, it was found that Samples 1, 2, and 3 were fine-grained soils with the percentage of soil passing the No.200 sieve greater than 50%. The USCS classification system shows that samples 1 and 2 of the soil are in the Lean Clay (CL) group, while sample 3 is in the Fat Clay (CH) group. Samples 1, 2, and 3 include soils with high plasticity because the PI value is >17. The results of testing the mechanical properties of the soil Sample 1 obtained the value of c = 0.1299 kg/cm2 and Ø = 13.2°, in Sample 2 obtained the value of c = 0.1075 kg/cm2 and the value of Ø = 11.2° and in Sample 3 obtained the value of c = 0.1275 kg/cm2 and the value of Ø = 11.9°. DCP testing on samples 1, 2 and 3 obtained CBR values of 5.35%, 4.73% and 3.15%. From the CBR results, it can be seen that the soil in this location has a low soil bearing capacity, so if it is to be used as a subgrade layer, it will be necessary to repair the soil first so that structural damage does not occur in the future. Soil improvement can be made by stabilizing the soil using natural materials to maintain environmental sustainability. Natural materials that can be used include sand with certain gradations, stone ash, palm shell ash, and various other natural materials.

Various functional and decorative pottery articles are produced of Pagerjurang, Klaten. The articles are made of raw material which are processed, shaped, dried, and burned in traditional kilns. In this study, a raw material of Pagerjurang Clay was characterized using XRD (X-ray Diffractometer) and SEM/EDX (Scanning Electron Microscope-Energy Dispersive X-ray). The results showed that Pagerjurang Clay was contained bentonite (24,87 %), quartz (37.08 %), feldspar (9.46 %), and illite (28.57 %), that consist silica 46.51% (w/w) and alumina 17.34 % (w/w), respectively. Pagerjurang Clay is red-browns color; very fine size; easy to break while dry, but very tough and sticky while wet; and easily made into the desired shape and elastic (not easily to be broken)

“…Research conducted by Vichi et al shown that ceramic membrane material is suitable to be used as a membrane in MFC, since it has the main ingredients in the form of silica (SiO 2 ), Titania (TiO 3 ), and Alumina (Al 2 O 3 ) [5]. While, research carried out by Winarno et al indicated that the clay contains SiO 2 , TiO 3 , Fe 2 O 3 , TiO 2 [6]. Therefore, clay is expected to be a suitable material to be used as Proton Exchange Membrane (PEM).…”

Proton Exchange Membrane (PEM), which can currently work well on Microbial Fuel Cells (MFC), cannot be produced efficiently. This is due to its high cost and properties such as high oxygen diffusion, presence of toxic sulphides, and a potential translucent substrate. Alternatively, clay mixed with activated Carbon will be used to produce PEM. This is because the crystalline clay content has characteristics that are useful in the manufacture of PEM. To produce cheap PEM, this research was conducted to produce rice husk activated Carbon (ACIRH) which was synthesized with sulfuric acid activator solution. In this case, ACIRH is activated by a two-step activation method. The two stages of the activation process were carried out by carbonizing ACIRH at a temperature of 500°C then impregnated with 2M of phosphoric acid solution with a weight ratio of 5:1 for 20 minutes resulting in an ACIRH surface area of 109.885 m2/gram. It was obtained using the method of Brunauer, Emmet, Teller (BET) with an Automated Chemisorption/Physisorption Surface Area Analyzer. ACRH pore size of 96 nm was obtained by applying the method of Density Function Theory (DFT). These results were confirmed by FESEM images showing the porous ACRH mesopore size. Meanwhile, X-Ray Diffraction Test and Rietveld Analysis showed that ACIRH contains 42.3% of Silica and 57.7% of Carbon. While the clay consists of 95.6% of Quartz (SiO2), 1.3% of Annite (KFe3 2+AlSi3O10(OH)2), 1.0% of Portlandite (Ca(OH)2), 0 9% of Brucite (Mg(OH)2), and 1.2% of Rutile (TiO2).
