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

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.
