Abstract

Sampah telah menjadi masalah yang belum dapat diatasi di Indonesia. Pengelolaan sampah belum secara maksimal dilakukan. Penanganan permasalahan sampah di Kota Pekanbaru harus dimulai dari sumbernya yaitu rumah tangga dengan melibatkan partisipasi aktif masyarakat. Tujuan kegiatan yaitu memberikan pemahaman dan kemampuan masyarakat dalam melakukan pengelolaan sampah, sehingga memiliki kesadaran sosial untuk merubah perilaku dalam mengolah sampah. Pengurangan sampah dengan metoda 3R (Reduce, Reuse, Recycle) berbasis masyarakat lebih menekankan kepada cara pengurangan sampah yang dibuang oleh individu, rumah, atau kawasan seperti RT ataupun RW. Pengelolaan sampah yang efektif di rumah dapat membuat kita terbiasa mengatur alur masuk-keluar sampah. Tidak ada lagi sampah yang tergeletak begitu saja. Setiap sampah akan ditempatkan sesuai peruntukannya. Sampah organik diproses menjadi kompos, sedangkan sampah plastik/kaleng/botol dibersihkan dan dikirimkan untuk didaur ulang. Kegiatan pengelolaan sampah efektif ini akan membuat lingkungan menjadi bersih dan nyaman.

Abstract

Banana peel is one of the wastes that can pollute the environment so it needs to be utilized. One of the ingredients in kepok banana peels is starch (carbohydrates). Banana peel starch can be converted into glucose by hydrolysis method. This study aimed to find out the effect of banana peel starch suspension levels on the reaction kinetics of the hydrolysis process. The hydrolysis process used 2 N oxalic acid with reaction times of 10, 20, 30, 40 and 50 minutes and the levels of suspension of kepok banana peel starch (gr/mlcamp) were 10/250, 20/250 and 30/250. The results showed that the optimum results were obtained at a suspension content of 10/250 gr/ml with a reaction conversion reaching 35% at a time of 50 minutes at a constant temperature of 100°C. Keywords : Hydrolysis, Banana Kepok, Reaction Kinetics

Abstract

Corrosion is one the problems that occur in the production process in oil and gas industries that can reduce material equipment such as tubing and flowline. corrosion is influenced by humidity and temperature. Corrosion can be control by using organic inhibitors because they are environmentally friendly. This research is a laboratory research that examines the effect of humidity using red ginger on reducing corrosion flow rate. Red ginger is used because it contains phenol antioxidants which can inhibit the corrosion flow rate. The variables used were variations in room humidity, 80%, and 90% and the inhibition time was 72 hours, 144 hours, and 216 hours. The results showed that the sample by adding red ginger inhibitor at room temperature humidity, 80%, 90% was able to maximize decrease in the corrosion rate. The sample with the addition of ginger inhibitor showed the higher the humidity value, the higher the corrosion rate where the highest corrosion rate was 0.1362 mmpy at 90% humidity, while the lowest humidity was obtained at room humidity of 0.0517 mmpy. Keywords : Humidity, Corrosion, Inhibitor, Red ginger, Coating

Abstract

Minyak bekas pakai atau biasa disebut jelantah sering sekali dibuang langsung di saluran pembuangan air, bak cuci piring, bahkan ke tanah. Meski terbilang praktis, cara tersebut nyatanya memiliki dampak buruk bagi lingkungan. Minyak jelantah tidak termasuk kategori limbah B3 dan tidak termasuk sampah. Tetapi minyak jelantah dianggap sebagai limbah. Minyak jelantah sebaiknya tidak dibuang sembarangan ke saluran air,karena dapat menyumbat saluran air dan dapat mencemari lingkungan. Lapisan minyak pada permukaan air dapat merusak ekosistem perairan. Pemakaian minyak jelantah berkali-kali tidak baik untuk kesehatan karena dapat meningkatkan risiko penyakit jantung dan gangguan kesehatan lainnya. Studi juga menyebutkan bahwa minyak goreng yang dipakai berkali-kali dapat menghasilkan berbagai senyawa, termasuk polisiklik aromatik hidrokarbon yang bersifat karsinogenik atau menyebabkan kanker. Adapun proses pembuatan sabun mandi ini dengan mencampurkan minyak jelantah dengan basa kuat NaOH dengan beberapa variabel zat pewarna makanan dari minyak jelantah hasil dari proses netralisasi.

Abstract

This study evaluates the potential of silica sand from Rupat Island, Indonesia, as a natural proppant for hydraulic fracturing, based on API RP 19C standards. Samples tested include unmodified sand, epoxy-coated sand (5% and 10%), and polyester-coated sand (5% and 10%). Key parameters assessed were roundness and sphericity, bulk density, turbidity, acid solubility, and crush resistance. Uncoated silica showed substandard morphology (0.47), while resin-coated samples reached 0.53 and polyester resin reached 0.54, meeting API criteria. Bulk density ranged from 1.53 to 1.60 g/cc, and turbidity values (2038 NTU) were within acceptable limits. This study demonstrates that applying a resin coating to Rupat silica sand notably enhances its physical and chemical properties, making it more suitable for use as a proppant. The coated sand exhibited an increase in bulk density, reaching 1.581.60 0.01 g/cc, which exceeds the API RP 19C minimum standard of 1.5 g/cc and suggests improved packing efficiency. Additionally, the acid solubility dropped from 2.8% in the uncoated sand to 1.22 0.01% in the coated samples, reflecting greater chemical resistance. Turbidity levels remained low, ranging from 20 to 135 2 NTU, well below the API limit of 250 NTU, indicating minimal generation of fine particles. In crush resistance tests, uncoated sand lost up to 13% weight at 5000 psi, while resin-coated variants showed improved performance, with weight loss reduced to 814% (5 mL and 10 mL epoxy resin) and 512% (5 mL and 10 mL polyester) at 6000 psi and 8000 psi. These results confirm that with appropriate surface modification, Rupat silica sand meets key API 19C criteria and holds strong potential as a local proppant material for hydraulic fracturingTRANSLATE with x EnglishArabicHebrewPolishBulgarianHindiPortugueseCatalanHmong DawRomanianChinese SimplifiedHungarianRussianChinese TraditionalIndonesianSlovakCzechItalianSlovenianDanishJapaneseSpanishDutchKlingonSwedishEnglishKoreanThaiEstonianLatvianTurkishFinnishLithuanianUkrainianFrenchMalayUrduGermanMalteseVietnameseGreekNorwegianWelshHaitian CreolePersian// TRANSLATE with COPY THE URL BELOW Back EMBED THE SNIPPET BELOW IN YOUR SITE Enable collaborative features and customize widget: Bing Webmaster PortalBack//

Abstract

The increasing household consumption of cooking oil has led to a rise in used cooking oil waste, which, if reused, can endanger health and, if disposed of carelessly, causes environmental pollution. This condition prompted the implementation of a community service program, which involved training women's religious study groups in Bumi Sejahtera Housing, Pekanbaru City, on how to use cooking oil in soap. This activity aimed to enhance community knowledge about the dangers of using used cooking oil, raise environmental awareness, and provide practical skills in processing used cooking oil into soap products that have both functional and economic value. The program was conducted in several stages, including a preliminary survey, material preparation, socialization, soap-making demonstrations, hands-on practice with participants, and post-training evaluation. The results showed high enthusiasm from participants, as reflected in their active involvement during discussions and practical sessions. Participants could produce soap from used cooking oil with good foaming quality and fragrance, making it suitable for household use. In addition, some participants expressed interest in continuing independent soap production by collecting used cooking oil from the surrounding community, thereby opening up opportunities for program sustainability and increasing the economic value of household waste. This program successfully improved community understanding of the impacts of used cooking oil, reduced potential environmental pollution, and provided skills that can be further developed into small-scale businesses.
