Abstract

Abstract— This research aims to determine the corrosion rate of different types of nails by immersing them in water of the same quality. The method used is weight loss method. Each nail was immersed in water for 1–7 days and then weighed every day. The highest corrosion rate was obtained for steel nails with an average corrosion rate of 0.09 mmpy and the lowest corrosion rate was obtained for wall nails with an average corrosion rate of 0.02 mmpy. The largest difference in nail weight after soaking was for the umbrella nail at 0.48 grams, while the smallest difference in nail weight was for the wall nail at 0.11 grams.

Abstract

Albumin plays important roles in the health of the body, such as stabilizing intravascular fluid pressure, facilitating molecular transport, and facilitating fluid movement in the body. The high cost of albumin, the limited availability of albumin sources, and the uncertainty surrounding its halal status underscore the imperative for this research. The objective of this study was to identify alternative sources of albumin, with a focus on exploring non-fish sources. Patin fish, a species endemic to Central Kalimantan, is a promising alternative due to its abundance and cost-effectiveness. The albumin content of steamed and dipped patin fish at 10, 15, 20, and 25 minutes was determined using the biuret method. The findings indicated that steaming yielded higher albumin content than dipping, with values of 4.41% and 3.88%, respectively. The optimal steaming duration was determined to be 15 minutes, while the optimal dipping duration was 20 minutes. These findings suggest that steaming may serve as a viable alternative source of fish albumin, offering a more economical option than snakehead fish.

Abstract

Mineral di Indonesia memiliki potensi besar untuk dikembang dalam sektor pertambangan dan industri salah satunya adalah silika. Silika oksida (SiO2) merupakan mineral berbentuk padatan yang banyak dianalisis dalam pengembangan penelitian sintesis nanomaterial. Pada penelitian ini sintesis nanomaterial silika dilakukan menggunakan metode sol-gel untuk memperoleh kristal murni yang sesuai standar. Tujuan dilakukan penelitian ini adalah menganalisis karakterisasi dan kemurnian hasil kristalisasi silika (SiO2) dengan metode sol-gel menggunakan XRD. Penelitian sintesis silika menggunakan metode sol-gel dilakukan di UPT Laboratorium Terpadu, Universitas Palangka Raya, Kalimantan Tengah. Hasil penelitian menunjukkan bahwa sintesis nanosilika dengan metode sol-gel terjadi dalam 2 tahapan reaksi, yaitu reaksi hidrolisis dan reaksi kondensasi, dimana diperoleh hasil puncak 2θ = 26,7° dengan nilai intensitas yang tinggi, nilai kristalinitas 64,4%, dan ukuran rata-rata kristal sebesar 1,2544 nm.

Abstract

Energi terbarukan adalah energi yang berasal dari sumber-sumber alami yang dapat diperbarui secara berkelanjutan, seperti sinar matahari, angin, dan air. Pengabdian masyarakat melalui kampanye media sosial yang menggunakan fitur Reels di Instagram bertujuan meningkatkan kesadaran generasi muda mengenai pentingnya energi terbarukan. Kampanye ini berfokus pada lima poin utama: proses pembentukan batubara, dampak negatif batubara, emisi gas dan kerusakan lingkungan dari industri batubara, potensi sumber energi terbarukan seperti matahari, angin, dan air, serta keunggulan energi terbarukan. Video kampanye tersebut berhasil menarik perhatian dengan 8.524 tayangan dan 691 likes. Analisis komentar menunjukkan bahwa lebih dari 90% respons berasal dari generasi muda, menunjukkan efektivitas pesan kampanye dalam menjangkau target audiens. Respon positif ini menandakan bahwa generasi muda dapat menerima dan memahami informasi yang disampaikan. Keberhasilan ini menunjukkan potensi besar media sosial sebagai platform edukatif. Penggunaan Instagram sebagai alat kampanye terbukti efektif dalam menyebarkan informasi ilmiah dan mendorong perubahan perilaku. Kampanye ini diharapkan dapat meningkatkan adopsi energi terbarukan di kalangan generasi muda. Hasil ini juga mendukung transisi menuju penggunaan energi yang lebih berkelanjutan dan ramah lingkungan.

Abstract

The escalation of crude oil exploitation poses significant risks of leakage and oil spills in the oceans. Therefore, this research aims to synthesize superhydrophobic sponges utilizing lignin derived from Oil Palm Empty Fruit Bunch (OPEFB) waste. Lignin was isolated from OPEFB with the addition of 15% NaOH, followed by neutralization and purification using H₂SO₄, which yielded a recovery of 30.3%. Subsequently, melamine sponges were modified via a facile dip-coating technique using a mixture of lignin, Polydimethylsiloxane (PDMS), and (3-aminopropyl)triethoxysilane (APTES). The physicochemical properties and material performance were characterized using 1H-NMR, FTIR, and Water Contact Angle (WCA) measurements. 1H-NMR analysis confirmed the successful isolation of the lignin structure, while FTIR spectra verified the effective deposition of the silane-lignin layer on the sponge skeleton. Contact angle analysis results indicated a significant surface transformation, where the sponge shifted from a superhydrophilic nature 0° to a highly superhydrophobic state (170.91°). With such performance, this material holds great potential as an effective, eco-friendly adsorbent for oil spill remediation in aquatic environments.
