Abstract

This study aims to determine the influence of promotion and knowledge on the interest of women from recitation groups in Kelapa District to conduct transactions at Islamic Banks. The type of research used is quantitative research with a sample of 161 respondents. With the data measurement technique using the Likert scale. The data was processed through the SPSS program version 25.0 with multiple linear regression analysis techniques. The research results show that: 1) Promotion partially affects the interest in conducting transactions at Islamic Banks with a t-calculated value (7.407) < t-table (1.654) or a significance value of 0.000 < 0.01. 2) Knowledge partially affects the interest in conducting transactions at Islamic Banks with a t-calculated value (3.268) > t-table (1.654) and a significance value of 0.000 < 0.01.

Abstract

This study examines the effect of different surfactants: Cetyltrimethylammonium Bromide (CTAB), Didodecyldimethylammonium Bromide (DDAB), and Methyltrioctylammonium Bromide (MTAB) on the synthesis of mesoporous TiO2 using the co-precipitation method. Characterization was performed using Raman Spectroscopy, BET (Brunauer-Emmett-Teller) surface area measurement, Differential Scanning Calorimetry (DSC), and X-ray Diffraction (XRD) techniques. The results indicate that the highest surface area was achieved by CTAB 98.32 m2/g, while MTAB yielded the greatest pore volume 0.2517 cc/g and the largest average pore diameter 10.498 nm. Furthermore, a simple catalytic activity test was performed through the degradation of methylene blue under UV irradiation, which showed that the TiO2–MTAB sample had the highest degradation rate of 0.032 min-1. This indicates a positive correlation between pore size and photocatalytic efficiency.

Abstract

Pembangunan ekonomi tidak terlepas dari peran manusia dalam mengelolanya. Manusia merupakan tenaga kerja, input pembangunan, dan juga merupakan konsumen hasil pembangunan itu sendiri. Permasalahan pokok dalam ketenagakerjaan adalah terletak pada tingkat kesempatan kerja. Penelitian ini bertujuan untuk menganalisis pengaruh upah minimum provinsi dan ekspor terhadap penyerapan tenaga kerja. Penelitian ini dilakukan di Provinsi Sumatera Utara. Variabel terikatnya adalah penyerapan tenaga kerja, variabel bebasnya adalah upah minimum provinsi dan ekspor. Data yang digunakan adalah data sekunder. Data sekunder diperoleh dari buku tahunan dan website resmi BPS Sumatera Utara. Adapun alat analisis yang digunakan adalah regresi linear berganda dengan bantuan program Eviews 8. Hasil penelitian ini menunjukan bahwa variabel upah minimum provinsi berpengaruh negatif dan signifikan terhadap penyerapan tenaga kerja dan ekspor berpengaruh positif dan signifikan terhadap penyerapan tenaga kerja di Provinsi Sumatera Utara. Hasil penelitian menunjukan bahwa koefisien determinasi (R square) sebesar 0.775168 yang artinya penyerapan tenaga kerja di Provinsi Sumatera Utara dapat dijelaskan oleh faktor variabel upah minimum provinsi dan ekspor sebesar 77,51%. Sedangkan sisanya sebesar 22,49% penyerapan tenaga kerja dijelaskan oleh variabel lain yang tidak dimasukan dalam model analisis dalam penelitian ini.

Abstract

This study investigates the electrochemical performance of a biobattery using orange peel extract as the electrolyte. Four experimental groups were evaluated using fresh and dried orange peel matrices combined with either distilled water or seawater. Open-circuit voltage (Voc), short-circuit current (Isc), and power density were measured. All instruments were calibrated prior to testing. The results show that citrus waste can generate measurable electrical energy, with Voc ranging from 0.83 V to 1.36 V and Isc ranging from 0.26 mA to 0.54 mA. Maximum power density achieved was 73 μW/cm². The findings demonstrate that orange-peel-derived electrolytes are promising sustainable alternatives for low-power applications.
