Abstract

The existence of Medium, Small and Micro Enterprises (MSMEs) in Indonesia has a big role in building the people's economy. So that micro entrepreneurs need to keep up with the times in developing their business. For this reason, knowledge of business actors is needed in forming the characteristics of the business they have, not only from product innovation but the physical condition and quality of a product needs to be developed so that buyers have a good visual of the product to be sold. Kerupuk Kedelai dan Bawang “Spesial” is one of the UMKM that needs to build product branding in order to compete in a wider market share. The activity process takes place using interview and observation methods at the location where it was made directly. Based on the observation results, it was found that these MSMEs need to remake the logo and product packaging to make it more attractive. The process of making logos and product packaging is assisted directly by the community service team by consulting directly with business owners. The creation of a logo and product packaging is the first step of Kerupuk Kedelai dan Bawang “Spesial” in building business branding to compete in the market.

Abstract

The presence of fly ash waste will have a negative impact on the environment so that it is necessary to handle it by utilizing fly ash waste. Silica purification by extracting silica from coal fly ash aims to minimize the levels of unnecessary metal oxides (impurities). This study aims to determine the characteristics of silica produced from fly ash waste, determine the best extraction conditions to produce silica and determine the effect of extraction pH on the silica produced. Silica extraction includes several processes including leaching, extraction, and precipitation. In this study, the manufacture of silica gel begins with washing fly ash with HCl. Silica is extracted using 3M NaOH with time variations of 100 minutes, 120 minutes and 140 minutes. Furthermore, the silica in the filtrate is precipitated with 1M HCl with a pH range of 3.4, and 5 and an aging process of 18 hours and dried using an oven and characterized with an XRF instrument. The results of this study indicate that the closer to neutral the addition of HCl pH used, namely 5, the higher the mass of silica from the extraction obtained up to a maximum at an extraction time of 120 minutes with a silica yield of 63.42%. Extraction with a time of 100 minutes and 140 minutes showed that the mass of silica from the extraction obtained was lower along with the increasing acidity of the addition of HCl. The results of the water content test obtained 1.53% and ash content of 9.345% of the silica produced met the requirements of the Indonesian National Standard (SNI) No. 06-2477-1991.

Abstract

The increasing volume of palm oil solid waste in Indonesia offers an opportunity for valorization into high-value materials. This study explores the potential of converting palm oil waste—comprising empty fruit bunches, shells, and fibers—into activated carbon through hydrochloric acid activation. The carbonization process was varied across five temperature levels (250–450 °C) and durations (60–120 minutes) to determine optimal conditions that meet the criteria of SNI 06-3730-2021. Post-carbonization, chemical activation was conducted using a 20% HCl solution. The most favorable result was obtained at 450 °C for 105 minutes, yielding activated carbon with 81.68% fixed carbon, 3.85% moisture, 10.29% volatile matter, and 4.18% ash content. Furthermore, adsorption capacities reached 763.98 mg/g for iodine and 178.82 mg/g for methylene blue. These findings suggest that palm oil waste can be effectively transformed into activated carbon that satisfies national quality standards.

Abstract

Industri gas asetilen menghasilkan limbah padat berupa kalsium hidroksida (Ca(OH)₂) yang termasuk dalam kategori limbah B3 (Bahan Berbahaya dan Beracun). Tingginya kandungan kalsium pada limbah ini dapat dimanfaatkan sebagai sumber kalsium alternatif dalam sintesis kalsium oksida (CaO) yang bernilai tambah. Penelitian ini bertujuan untuk mengkaji pengaruh variasi pH dan suhu sintering terhadap karakteristik CaO dari limbah Ca(OH)₂ produksi gas asetilen. Proses sintesis dilakukan melalui metode presipitasi dengan pengkondisian pH 10, 11, 12, 13, dan 14, dilanjutkan dengan proses sintering pada suhu 550 °C, 650 °C, 750 °C, 850 °C, dan 950 °C. Karakterisasi meliputi analisis yield, penentuan kadar kalsium menggunakan spektrofotometer serapan atom (SSA), serta pengamatan morfologi menggunakan Scanning Electron Microscopy (SEM). Hasil penelitian menunjukkan bahwa peningkatan pH berpengaruh terhadap kenaikan yield CaO, sedangkan peningkatan suhu sintering meningkatkan kadar kalsium akibat dekomposisi Ca(OH)₂ yang lebih optimal. Kondisi terbaik diperoleh pada pH 14 dan suhu 950 °C dengan kadar kalsium 69,22%. Ukuran partikel CaO yang terbentuk adalah 140,5 nm, yang masih berada di atas rentang standar nanopartikel (1–100 nm) berdasarkan ISO 80004-1:2023. Temuan ini menunjukkan limbah Ca(OH)₂ produksi gas asetilen berpotensi dimanfaatkan sebagai bahan baku CaO, meskipun diperlukan optimasi lebih lanjut untuk menghasilkan material berskala nano.
