Abstract

Furfural has emerged as a value-added chemical product which generated from hemicellulose-base biomass, in the context of hardwood it called as biorefining. Several methods have been developed to produce furfural using both hydrothermal and catalytic processes. In this study, hydrolysate is used as feedstock for generating furfural by using diluted sulfuric acid and aluminium chloride. Temperature and reaction time has been considered as the valuable variable. Hydrolysate was charged with the acid-catalyst for around 90 min at certain temperature. The product analyzed by using fourier transform index refractory and excess bromine method. At this time, the highest yield of furfural for non-catalyst process was achieved at 120 oC for 90 min. Diluted acid solution by hydrochloric acid and AlCl3 1% managed to increase furfural production from hydrolysate in the mild temperature.

Abstract

The prevalence of anemia according to the World Health Organization (WHO) in 2022, reached 50-65% worldwide, in Indonesia adolescent girls experienced anemia 18% in 2023, Lampung Province showed adolescents experiencing anemia 63% in 2023, in Tanggamus district as much as 8.7% and West Kotaagung District by 4.9% in 2023. One of the causes of anemia is iron deficiency, this can be prevented by giving blood supplement tablets in accordance. The dose given is one tablet every week. The purpose of this study was to determine the correlation between knowledge and adherence to the consumption of blood supplement tablets in adolescent girls at MTs NU Negarabatin West Kotaagung, Tanggamus District. The research method used was quantitative research with a cross-sectional approach. The research was conducted at MTs NU Negarabatin. The population of this study were all adolescent girls totaling 60 people. The sample technique used was total sampling. Data collection using a questionnaire that has been tested for validity and reliability. Data analysis was univariate and bivariate using Fisher Exact Test. The results showed that the knowledge of adolescent girls was mostly low, namely 36 adolescent girls (60.0%). Adherence to the consumption of blood supplement tablets in adolescent girls is not compliant, which amounted to 58 adolescent girls (96.7%). The Fisher Exact Test results obtained p-value = 0.156, so it was concluded that there was no correlation between knowledge and compliance with the consumption of blood supplement tablets at MTs NU Negarabatin. It is expected for teachers to provide support and for health workers to further increase socialization and counseling to adolescent girls about anemia and the importance of consuming blood supplement tablets

Abstract

This community service program was implemented to address the problem of the low quality of students' Quran reading at TPQ Al-Litfilah Nur, Situhiang Village, which was caused by the lack of implementation of a structured and sustainable tahsin learning method. This activity aims to improve students' Quran reading skills through training and mentoring using the Tilawati method combined with the Asset-Based Community Development (ABCD) approach, so that the potential and resources of the community can be optimized. The program was implemented in stages, including mapping the initial conditions of students' and teachers' abilities, training TPQ teachers on the principles and techniques of the Tilawati method, mentoring the learning process in a classical and individual manner, and evaluating the development of students' reading skills. The results of the activity showed a significant increase in the accuracy of makhraj, the application of basic tajwid, and the fluency of students' Quran reading. In addition, TPQ teachers experienced an increase in pedagogical competence and were able to apply the Tilawati method independently in teaching and learning activities. These findings indicate that strengthening community assets through targeted and participatory training can create meaningful and sustainable changes in improving the quality of Qur'an learning at the TPQ level.

Abstract

The synthesis of the ZnO-biochar composite from palm kernel shell biomass waste has been accomplished through the utilization of thesolvothermal method, yielding a satisfactory outcome. The resulting composite, a combination of ZnO and biochar, has been utilized in the degradation of methylene blue waste compounds. The objective of this research is to synthesize ZnO-biochar composites from palm shells, and to determine the optimal solvothermal temperature and duration. This research was initiated with the preparation of palm shells into biochar. Subsequently, the ZnO-biochar composite was synthesized with variable solvothermal temperatures and solvothermal times. The ZnO-biochar composite was characterized using analytical techniques including SEM-EDX, FT-IR, XRD, BET and UV-vis DRS. The most effective degradation of methylene blue was exhibited by the ZnO-biochar composite sample synthesized at a solvothermal temperature of 180 ̊C and a solvothermal time of 10 hours, achieving a degradation of 88.29%. The enhanced photodegradation performance of this composite sample is attributed to its high surface area, capacity for visible light absorption, and the dimensions of the active crystals, which can account for the high performance of the ZnO-biochar composite for photocatalytic degradation.

Abstract

The high volume of wheat imports in 2022, which reached 9.35 million tons, increases the risk of entry of the quarantine plant pest organism Tilletia sp., classified as Group 1 Category A1. These groups and categories cannot be treated and do not yet exist in Indonesia. Therefore, monitoring the fungus Tilletia sp. must be severe and handled appropriately. This activity aims to understand the flow of quarantine requirements and characterization of Tilletia sp. as a determinant of import approval at the Animal, Fish, and Plant Quarantine Center. The flow of quarantine requirements is implemented when the importer prepares the application file online, Phytosanitary Certificate, Invoice, Bill of Lading, Shipping Instruction, Prior Notice, Certificate of Analysis, Health Certificate, and Application for Import. Wheat commodities, if infected with Tilletia sp., will be detained, and a detention warrant will be issued; if treatment is not given, a destruction order and an extermination report will be issued. Characterization of Tilletia sp. was determined based on the frequency of washing test results. Wheat samples with Tilletia sp. >10 times must be treated with heat treatment to kill the development of spores.
