Abstract

This study aimed to calculate the volume of air required by a blower to transfer tapioca flour from the dryer unit to the shifter unit in a factory with a production capacity of 35 tons per day. The flour transfer process utilizes a blower to generate sufficient airflow. Still, it often experiences instability caused by factors such as blower speed fluctuations, material load variations, and pipe blockages. The research was conducted over one month using data collection methods that included interviews and direct observation. Analysis results showed that the cross-sectional area of the blower pipe was 0.6358 m², the airflow velocity was 1.517 m/s, and the airflow rate reached 0.965 m³/s. The total air volume required by the blower to move the flour was calculated to be 27,792 m³ per day. The findings highlight the importance of properly regulating and maintaining the blower system to ensure efficiency in tapioca flour production.

Abstract

Kesadaran menjaga lingkungan yang bersih serta menanam pohon dilahan kosong atau lahan sempit bagi masyarakat perkotaan termasuk di Tangerang yang rata-rata pekerja pabrik agak sedikit sulit. Kesibukan dan padatnya aktivitas setiap harinya menjadikan mereka enggan untuk membersihkan lingkungan sekitar yang bukan lahan mereka. Tujuan dari kegiatan PkM ini untuk memberikan pemahaman kepada masyarakat di Pos Bitung mengenai lingkungan yang bersih dan penanaman tanaman untuk keseimbangan lingkungan. Metode yang digunakan tim terjun langsung dengan ceramah, membersihkan dan menanam pohon secara langsung. Hasil dari kegiatan ini berupa pemahaman masyarakat terhadap lingkungan sekitar. Monitoring dan evaluasi dilakukan secara langsung dan hasilnya semua memberikan kesan yang positif. Kegiatan serupa akan terus berlanjut secara kontinyu

Abstract

Digital transformation has become a critical pathway for strengthening financial management practices among micro, small, and medium enterprises (MSMEs), particularly in developing economies. Despite increasing access to digital financial technologies, empirical evidence indicates that many MSMEs adopt these tools in a fragmented and non-strategic manner. This study aims to explore how MSME actors experience digital transformation in financial management, identify the practical changes arising from the use of digital financial tools, and examine the barriers and enabling factors shaping this transformation. Employing a qualitative research design, this study draws on in-depth interviews, non-participant observations, and document analysis involving 24 MSME owners and managers across micro, small, and medium enterprises in Banten Province, Indonesia. Thematic analysis reveals that digital transformation among MSMEs unfolds incrementally, beginning with basic tools such as digital payments and mobile banking, largely driven by customer demand rather than strategic intent. While digital tools improve transaction recording accuracy, financial transparency, and operational efficiency, their utilization remains predominantly operational, with limited progression toward analytical or strategic financial management. Key challenges include inadequate digital and financial literacy, trust concerns related to data security, cost constraints, infrastructural limitations, and entrenched traditional practices. The findings underscore that digital transformation in MSME financial management is a socio-technical process shaped by interactions between technology, managerial capabilities, and institutional context. This study contributes to the literature by providing rich qualitative insights from an underexplored regional context and offers practical and policy-relevant implications for fostering inclusive, context-sensitive digital transformation among MSMEs.

Abstract

This research explores the physicochemical characteristics of activated and sulfonated carbons derived from palm empty fruit bunches (OPEFB) as renewable raw materials, and assesses their catalytic performance in the esterification of waste cooking oil (WCO) for biodiesel synthesis. Activated carbon was sulfonated via exposure to high-concentration sulfuric acid (H₂SO₄) at 7%, 10%, and 13%, facilitating the incorporation of –SO₃H groups. A range of analytical techniques, including TGA, DTA, FTIR, BET, and SEM, was employed to characterize the synthesized materials. Among the synthesized catalysts, the sulfonated carbon with 10% acid treatment (SA 10%) exhibited the most favorable characteristics: demonstrated a surface area of 41.895 m²/g and retained its structure under thermal stress, and a strong presence of sulfonic functional groups. Esterification tests at 65 °C for 2 hours showed a maximum yield of 43.28% using 3 g of SA 10%, while 5 g resulted in a lower yield of 30.32%. The results demonstrate that SA 10% is a promising eco-friendly heterogeneous catalyst for converting low-cost, waste-based feedstocks into biodiesel under mild reaction conditions.

Abstract

The purpose of this study is to investigate the effect of brand leadership (which consists of the dimensions of quality, value, innovation, and popularity) perceived by consumers of an e-commerce website on customer satisfaction among private college students. In addition to testing the effect of customer satisfaction on repurchase intention. The sample of this research was taken from 1026 students using simple random sampling techniques and using SEM (Structural Equation Model) with SmartPLS software version 3.0 as a statistical tool. The results of this study indicate that all dimensions of brand leadership have a positive and significant effect on customer satisfaction. Likewise, the customer satisfaction variable has a positive and very significant effect on repurchase intention among respondent students. The quality dimension has the greatest influence on increasing customer satisfaction on e-commerce sites. Then followed by the dimensions of value, innovation, and popularity dimensions.

Abstract

Low rank coal (LRC), due to its abundance and carbon richness, represents a promising and sustainable precursor for graphene synthesis. This study compares the effects of different solvents CTAB (2%), NaOH (1N), H₂SO₄ (1N), and isopropyl alcohol (IPA)—on the exfoliation efficiency of LRC using a multi-stage ultrasonication approach. The resulting materials were characterized by FTIR, SEM, TEM, and XRD to evaluate their structural, morphological, and chemical properties. The findings reveal that IPA provides the most effective exfoliation, yielding few-layer graphene (FLG) with minimal oxidation and structural distortion. FTIR spectra showed reduced hydroxyl and carbonyl peaks in IPA-treated samples, while SEM and TEM confirmed more open and less-stacked layers. XRD analysis indicated decreased crystallinity and larger interlayer spacing. These results demonstrate that solvent selection plays a critical role in determining exfoliation performance, with IPA emerging as the most efficient and environmentally friendly medium for graphene production from LRC.
