Abstract

AbstrakTingginya penggunaan minyak bumi menyebabkan cadangan minyak bumi menipis, ini dikarenakan minyak bumi merupakan sumber daya alam yang tidak dapat diperbaharui. Kondisi ini menyebabkan perlu dilakukannya pencarian energi alternatif yang dapat mengurangi penggunaan minyak bumi, salah satunya yaitu biodiesel. Biodiesel terbuat dari minyak nabati sehingga dapat diperbaharui karena banyak terdapat di alam. Pembuatan biodiesel dapat dibuat menggunakan minyak jelantah melalui proses transesterifikasi. Minyak jelantah akan bereaksi dengan larutan kalium metoksi yang berasal dari campuran metanol degan katalis KOH. Desa nelayan di Karangantu sangat berpotensi untuk pemanfaatan minyak jelantah untuk dirubah menjadi biodiesel sebagai bahan bakar mesin kapal. Metode pelatihan menggunakan demonstrasi dan ceramah. Objek pengabdian adalah perwakilan masyarakat nelayan karangantu berjumlah 25 orang. Berdasarkan hasil kegiatan menunjukan bahwa penyuluhan yang dilakukan bermanfaat bagi masyarakat. Hal ini dibuktikan dari materi pertama mengenai bahaya dan potensi pemanfaatan minyak jelantah yang dirasa sangat bermanfaat. Kemudian kegiatan demonstrasi merubah minyak jelantah menjadi biodiesel juga dirasa sangat bermanfaat menurut nelayan karena hal tersebut dapat menjadi alternatif bahan bakar untuk mesin kapal yang menggunakan mesin diesel. Berdasarkan data yang diperoleh, kegiatan pelatihan mendapatkan skor keefektifan yaitu sebesar 3,50 dan masuk dalam kategori efektif. Hal ini menunjukan bahwa kegiatan pelatihan memberikan dampak positif dalam meningkatkan pengetahuan dan keterampilan para nelayan.Kata kunci:  minyak jelantah, biodiesel, nelayan, Karangantu, reaktor   AbstractThe high use of petroleum causes petroleum reserves to run low, this is because petroleum is a non-renewable natural resource. This condition causes the need to search for alternative energy that can reduce the use of petroleum, one of which is biodiesel. Biodiesel is made from vegetable oil so it can be renewed because it is abundant in nature. Biodiesel can be made using used cooking oil through a transesterification process. Used cooking oil will react with a solution of potassium methoxy derived from a mixture of methanol with a KOH catalyst. The fishing village in Karangantu has the potential to utilize used cooking oil to be converted into biodiesel as fuel for ship engines. The training method uses demonstrations and lectures. The object of service is the representatives of the Karangantu fishing community, totaling 25 people. Based on the results of the activity, it shows that the counseling provided is beneficial to the community. This is proven from the first material regarding the dangers and potential use of used cooking oil which is considered very useful. Then the demonstration activity of changing used cooking oil into biodiesel is also considered very useful according to fishermen because it can be an alternative fuel for ship engines that use diesel engines. Based on the data obtained, the training activities get an effectiveness score of 3.50 and fall into the effective category. This shows that training activities have a positive impact in increasing the knowledge and skills of fishermen.Keywords:  used cooking oil, biodiesel, fishermen, karangantu, reactor.

Abstract

Air tanpa dilakukan proses demineralisasi untuk keperluan proses (seperti untuk keperluan reaksi kimia, umpan air boiler, dan separasi) akan memicu munculnya kerak dan berpotensi meningkatkan laju korosi, serta meningkatnya produk samping jika digunakan pada proses reaksi. Produk samping pada proses reaksi, dapat berpotensi menjadi limbah jika nilai keekonomian dari produk tersebut rendah. Kerak yang muncul pada peralatan perpindahan panas seperti boiler akan berakibat pada nilai efisiensi boiler turun, yang dapat mempengaruhi emisi gas buang dari boiler tersebut, dan semuanya akan mempengaruhi kualitas lingkungan sekitar. Pengolahan air sebelum digunakan untuk unit proses merupakan langkah pencegahan terhadap pencemaran lingkungan yang nanti akan timbul pada prosesproses selanjutnya. Tujuan dari penelitian ini adalah menganalisa pengaruh laju alir dan tinggi resin di dalam unggun terhadap jalannya proses pertukaran ion pada proses dimeralisasi air berbasis penurunan kesadahan air dan TDS (Total Dissolved Solid) serta efisiensi yang dihasilkan. Harapannya diperoleh kondisi operasi yang efektif , efisien serta tetap ekonomis, dalam hal pengolahan air. Penelitian dilakukan pada laju alir 2,90- 4,33ml/s (10,44 – 15,59 liter/jam) dan ketinggian resin 14 dan 17 cm. Hasil penelitian menunjukkan bahwa pada rentang laju air umpan 2,90 - 4,33 ml/s dan tinggi unggun 14 dan 17 cm dihasilkan kondisi terbaik pada laju air umpan 4, 33 ml/s pada tinggi unggun 14 cm, dengan efisiensi penurunan kesadahan mencapai 93, 56%.

Abstract

Biodiesel is a type of alternative diesel fuel derived from plant oils or animal fats produced through the transesterification process. Previous biodiesel studies have stated that esterification reactions are carried out when the content of free fatty acids in vegetable oil raw materials is greater than 2%. If the content of free fatty acids is smaller than 2% then the process of transesterification reaction is carried out.                The research aims to find out the optimum operating conditions of biodiesel manufacturing with low grade CPO raw materials using the esterification and transesterification process. The research began with the analysis of low grade CPO raw materials, then carried out the esterification process with the H2SO4 catalyst and continued the transesterification process with NaOH catalyst. Fixed variables in the study were oil volume, 1% of H2SO4 catalyst, mole ratio of oil and methanol 1:6, reaction time and reaction temperature of 60 oC. The fixed variables in the study were NaOH catalyst ratios in the transesterification process of 0.5%, 1% and 1.5%. The oil obtained is analyzed the content of free fatty acids, density, viscosity, and water content.                The results of the study obtained the physical and chemical properties of low grade CPO, namely water content 0.042% and free fatty acids 49.03. Optimum operating conditions are obtained with a catalyst ratio of NaOH of 1% with a methyl ester yield of 60.80%. The resulting methyl ester has a viscosity value of 5,381 cSt, a density of 870 kg/m3, an acidic content of 0.11 and a water content of 0.028.

Abstract

The study investigates the impact of surfactant concentration and mixing time on the physical properties and stability of emulsions in non-baffle mixing systems. Surfactants, known for their ability to reduce interfacial tension, play a pivotal role in enhancing emulsion stability by promoting uniform droplet dispersion and reducing coalescence. Experiments were conducted using varying surfactant concentrations (0, 5, and 10 mL) to evaluate their effects on key parameters such as density, viscosity, Reynolds number, emulsion height, and stability over time. The results revealed that higher surfactant concentrations significantly improved emulsion uniformity and stability, with the 10 mL concentration yielding the most consistent outcomes. However, the absence of baffles introduced challenges, including prolonged mixing times and stratification tendencies, underscoring the need for optimized mixing configurations. These findings have practical implications for industries reliant on stable emulsions, highlighting the importance of balancing surfactant concentration and mixing dynamics to achieve efficient and cost-effective processes.

Abstract

Chitosan, a biopolymer derived from chitin-rich biomass such as crustacean shells, has garnered attention for its biodegradability, biocompatibility, and wide-ranging applications. However, conventional chemical extraction methods relying on strong acids and bases pose significant environmental and safety concerns, often leading to molecular degradation and low product quality. This study explores the use of deep eutectic solvents (DESs) as a green alternative for chitosan extraction. DESs, formed from combinations of hydrogen bond donors and acceptors, offer tunable properties, lower toxicity, and recyclability. The article highlights the structural advantages, extraction efficiency, and environmental benefits of DESs over conventional methods. It also examines the integration of process intensification technologies, such as microwave and ultrasound-assisted extraction, to enhance yield and reduce energy consumption. The findings underscore DESs’ potential to produce high-purity chitosan while supporting sustainability goals and industrial scalability, offering a viable pathway toward eco-friendly biopolymer processing.
