Abstract

Pesantren as an educational institution and center of the spread of Islam is born and developed since the beginning of the arrival of Islam in the archipelago. This institution stood for the first time in the days of Walisongo. Sufism is part of the Islamic teachings of the easiest and quickly adapt to the traditions and even the mystique of the local community. Significant influential figures include: al-Ghazali who has described the moderate concept of tasawuf akhlaqi accepted in all circles of the fuqaha ', Ibn' Arabi, as his work strongly influences the teachings of almost all Sufis, as well as the founders of the tarekat such as' Abd. al-Qadir al-Jaylani whose teachings form the basis of the Qadiriyah congregation, Abu al-Najib al-Suhrawardi, Najmudddin al-Kubra whose teachings were very influential on the tarkeat of Naqsyabandiyah, al-Hasan al-Syadzali Sufis African origin and founder of the tarekat Syadzaliyah, Bahauddin al -Bukhari al-Naqsyabandi, and 'Abdullah al-Shattar. And the above mentioned Sufism method developed is the continuity of Sufism of al-Ghazali.

Abstract

Researchers are interested in investigating the optimum features of Sesbania grandiflora fibers (SGs) and Leucaena leucocephala fibers (LLs) for application in a wide range of applications. The purpose of this study was to explore the effects of NaOH and bleaching on the chemical characteristics, density, moisture content, and functional groups of sesbania g. and leucaena l. fibers. SGs and LLs fibers were chemically changed in various ways, including alkalization with 5% NaOH for 2 hours and bleaching with sodium chlorite (NaClO2) and acetic acid (CH3COOH). The results of the study showed that the cellulose, lignin, and hemicellulose content of the modified fiber was generally lower than that of the raw fiber. This was explained by the hydrolytic agents NaOH and bleaching causing damage to the cellulose chains and bond modifications. It was discovered that NaOH treatment was more effective at removing lignin and hemicellulose components in addition to cellulose, based on the functional groups seen in FTIR spectra. After the alkali and bleaching processes, the water content of SGs/NaOH, LLs/NaOH, SGs/bleaching, and LLs/bleaching fibers was reduced to 5.4 ± 0.89 %, 6.23 ± 0.87 %, 7.12 ± 1.02 %, dan 0.22 ± 0.21 %, respectively. This is also because the fiber has a relatively high fiber density of between 0.2 and 0.3 g/cm3, which is caused by the loss of non-fiber substances that are linked to the fiber. The results show that PFs treated with bleaching, NaOH, and raw fibers have the potential to be used as fillers in biocomposites and as substitute materials for glass fiber in the textile industry.

Abstract

Silver nanoparticles (AgNPs) are being studied extensively as nanostructures for novel and enhanced biomedical applications. Nanoparticles in bone grafts have been shown to speed up fracture healing by providing a finer structure for bone tissue engineering. They are known to have excellent antimicrobial properties due to their high surface-to-volume ratio and small particle size, without affecting the material's mechanical properties. AgNPs' distinct property makes them the preferred filler in a wide range of biomaterials, where they play an important role in enhancing properties. AgNP-containing biomaterials can be easily tailored to meet specific requirements in the development of bone tissue. Adjusting size, shape, composition, and surface charge can enhance their effectiveness in interacting with bone cells, promoting cell attachment, and delivering growth factors. Using AgNP-based biomaterials can help prevent or reduce the formation of biofilms. The utilization of these materials in bone tissue engineering has demonstrated potential in treating musculoskeletal conditions and bone traumas. They are versatile for various applications such as bone implants, scaffolds, wound dressings, and antibiotic delivery systems. This review will cover several special topics, including silver-based biomaterials, toxic properties, morphology and mechanical properties of silver-based biomaterials, and applications of silver-based biomaterials in medical applications.

Abstract

Used light steel is used extensively in construction projects and is only provided to collectors at a reduced cost. It is derived from the leftover light steel building components. The goal of this project is to make a grill out of the leftover light steel parts that will withstand heat better and be more valuable than it was previously. The grill's shape facilitates easy heat absorption by the cooked material. This fish grill is made by first gathering leftover light steel, then bending and attaching the steel to form the grill using bolts. The activity's outcomes demonstrate that the grill made from leftover light steel is capable of producing consistent heat, allowing the fish to be cooked to perfection without being overly dry or scorched on the outside. Light steel additionally has an excellent level of heat resistance at high temperatures, extending the tool's service life and, eventually, raising UMKM's earnings.

Abstract

Our research focuses on enhancing the potential of pumpkin seed waste extract as a sustainable corrosion inhibitor for metal (Fe) in 1 M HCl solution. Phytochemical screening and antioxidant activity were identified. Various investigative methodologies including experimental techniques such as Potentiodynamic Polarization (PDP) were used to evaluate the effectiveness of these pumpkin seed waste extract inhibitors in inhibiting corrosion. Electrochemical results showed that the effectiveness of the inhibitor was concentration dependent here reaching 83.11% at 3000 g/L pumpkin seed waste extract inhibitor. The PDP showed that the mixed inhibition control effectively retarded the corrosion of the metal. Furthermore, the adsorption behavior of the pumpkin seed waste extract inhibitor onto the metal follows the Langmuir isotherm model with physisorption properties. The adsorption mechanism of the inhibitor on the metal surface successfully formed a protective film on the metal surface thereby reducing the corrosion rate.
