Abstract

This study optimized a co-solvent free electrochemical method for biodiesel synthesis using graphite electrode and waste concrete heterogeneous catalyst. Various parameters were evaluated, including: applied voltage (9.6, 14.4, 19.2 V), catalyst particle size uniformity (unfiltered and filtered with 150 mesh), and reaction time (15, 30, 120, 240 min). The results obtained 100% FAME content and 78.51% of biodiesel yield that were achieved at 14.4 V within 30 min using filtered catalyst and cooking oil feedstock. However, a slight decline was observed with the use of waste cooking oil. This optimized method offers a reliable and simple condition for mass biodiesel production.

Abstract

AbstractScientific literacy is the main key to face challenges in the 21st century to solve problems in everyday life such as water and food, energy, disease, and climate change. Lack of understanding of 'what is nano', the foundation of various disciplines, widely used jargons, and various scientific terms that are difficult to understand, make nanotechnology difficult to be accepted by the wider community. However, this can be overcome by simplifying these complex concepts and presenting them in an interesting way. Media such as story books, infographic posters, interactive videos can be used to explain complex concepts in a simple form. Abroad, there are many story books that raise the concept of nanotechnology and present it in a simple and interesting way. Therefore, the form of picture story books for early childhood and elementary schools can be an effective delivery medium for the concept of nanotechnology.Keywords: education, early children, role of nanotechnology, story books AbstrakLiterasi sains merupakan kunci utama untuk menghadapi berbagai tantangan pada abad 21 untuk memecahkan masalah dalam kehidupan sehari-hari seperti air dan makanan, energi, penyakit, dan perubahan iklim. Hal ini juga berdampak terhadap kurangnya pengetahuan masyarakat Indonesia terhadap teknologi yang berkembang saat ini, salah satunya nanoteknologi. Kurangnya pemahaman tentang ‘apa itu nano’, fondasi dari macam-macam disiplin ilmu, jargon-jargon yang banyak dipergunakan, dan berbagai istilah ilmiah yang sulit dipahami, menyebabkan nanoteknologi sulit diterima oleh masyarakat luas. Namun, hal ini bisa diatasi dengan penyederhanaan konsep-konsep rumit ini dan menyajikannya dengan cara yang menarik. Hal ini sudah banyak dilakukan oleh bidang ilmu lain. Media seperti, buku cerita, poster infografis, video interaktif dapat digunakan untuk menjelaskan konsep rumit dalam bentuk yang sederhana. Di luar negeri sudah banyak buku cerita yang mengangkat konsep nanoteknologi dan menyajikannya secara sederhana dan menarik. Oleh karena itu, bentuk buku cerita bergambar untuk anak usia dini dan sekolah dasar dapat menjadi media penyampaian yang efektif untuk konsep nanoteknologi.Kata kunci: anak usia dini, buku cerita, peran nanoteknologi, pendidikan

Abstract

Salah satu dari tiga pilar pendidikan tinggi atau tridharma di Indonesia adalah pengabdian kepada masyarakat bagi sivitas akademika untuk melatih inovasi dan teknologi yang ditunjukkan dengan kemampuannya dan memberikan manfaat bagi banyak orang. Untuk itu, dosen Departemen Teknik Nanoteknologi, Fakultas Teknologi Maju dan Multidisiplin, Universitas Airlangga Surabaya mengadakan program pengabdian masyarakat yang diberi nama “Penerapan Nanoteknologi dalam Kehidupan: Pendidikan pada Siswa SMA” yang bertujuan untuk menyebarluaskan pengetahuan dan informasi tentang nanoteknologi khususnya untuk siswa sekolah menengah. Sebagai inovasi dan teknologi terkini, nanoteknologi masih belum populer di kalangan pelajar SMA di Indonesia. Dengan demikian, pengabdian masyarakat ini juga diharapkan dapat meningkatkan dan menyeimbangkan pengetahuan masyarakat serta mendukung tujuan ke-4 Sustainable Development Goals (SDGs) untuk pendidikan berkualitas yang dilakukan secara online saat ini. Kegiatan tersebut diikuti oleh 129 peserta dari sekolah mitra (SMAN 1 Sidoarjo, SMAN 1 Pamekasan dan SMAN 1 Trenggalek) dan beberapa peserta dari sekolah nonmitra di Jawa Timur. Webinar ini dilakukan dengan mengklarifikasi penggunaan nanoteknologi dalam kehidupan sehari-hari serta contoh-contoh nanopartikel emas yang disintesis baik secara kimiawi maupun biologis. Perluasan dan transfer pengetahuan berhasil ditunjukkan dengan rata-rata skor post-test (68) meningkat berbanding terbalik dengan skor pre-test (54). Kegiatan ini juga diharapkan dapat meningkatkan pengetahuan mahasiswa tentang perkembangan teknologi terkini dan minat mahasiswa terhadap ilmu pengetahuan dan teknologi sehingga nanoteknologi dapat digunakan untuk memecahkan masalah yang ada di Indonesia.

Abstract

Neuraminidase sensors have been developed using platinum (Pt) and platinum-modified boron-doped diamond (Pt-BDD) electrodes based on the difference of electrochemical responses of zanamivir in the absence and in presence of neuraminidase. Cyclic voltammetry of zanamivir showed that the presence of zanamivir decreases the oxidation-reduction peak currents of Pt. The responses were found to be linear in the zanamivir concentration range of 7.5-150 μM. Comparison between Pt-BDD and Pt bulk electrodes showed that Pt-BDD offers approximately two times higher sensitivity of zanamivir responses than Pt bulk. Further comparison to gold-based electrodes showed that Pt-based electrodes provided about one order higher sensitivity of zanamivir responses. In the presence of neuraminidase, the oxidation-reduction currents of Pt again increase. Observation on the oxidation currents in the system with 2 x 10-5 M zanamivir showed that the responses were linear in the neuraminidase concentration range of 5-20 mU. Good reproducibility with an RSD < 3 (n = 10) was achieved even when the measurements were performed in a mucin matrix,suggesting that Pt-based electrodes are suitable to be applied for the detection method of neuraminidase.

Abstract

CO2 electrochemical reduction (CO2ER) activity is known to be influenced by electrode materials. In this study, we report the fabrication of a copper-nickel-modified boron-doped diamond (CuNi-BDD) electrode using wet chemical seeding and electrodeposition. Annealing was performed to improve the stability of the modified electrode during elec-trolysis. Characterization of the modified BDD electrodes shows successful deposition without damage to the surface of the BDD support material. CO2ER was conducted with the CuNi-BDD electrode, which produces various important products including methanol, formic acid, CO, and CH4. Additionally, a different applied potential affected the product distribution. CO2ER was also conducted on the surfaces of Cu-BDD and Ni-BDD electrodes for comparison.

Abstract

Levofloxacin (LEV) was known as one of the fluoroquinolone antibiotics that widely used as an antibacterial agent. Monitoring of LEV is important due to its negative side effect on humans. The determination of LEV was studied for the first time on nickel modified on a boron-doped diamond (NiBDD) electrode using the square wave voltammetry (SWV) method to improve the catalytic and sensitivity of the sensor. The response was linear in the range of 30–100 mM LEV. LEV sensor on NiBDD was found to be selective in the presence of urea, glucose, and ascorbic acid interferences. Good reproducibility with % a relative standard deviation of 1.45% (n = 10) was achieved. Therefore, the NiBDD electrode could be potentially applied for the real detection method of LEV.

Abstract

The Cu-Ag core-shell nanoparticles (Cu@Ag NPs) are prepared by chemical reduction method with polyvinyl pyrrolidone (PVP) was used as a capping agent, ascorbic acid (C6H8O6) and sodium borohydride (NaBH4) was used as a reducing agent. Cu@Ag NPs were synthesized with three variations of (Cu:Ag) 1:3, 1:4, and 1:5.. The uniformity of Cu@Ag NPs samples with three variations was verified by the particle size analyzer test. The sizes of Cu@Ag 1:3, 1:4, and 1:5 was obtained sequentially at the range of 270-280 nm, 300-304 nm, and 690-700 nm respectively. Indications of the successful synthesis of Cu@Ag nanoparticles can be seen from UV-Vis spectra of Cu@Ag 1:3, 1:4, and 1:5 respectively forming AgNP at wavelengths of 434 nm, 450 nm, and 428 nm Furthermore, the stability of Cu@Ag NPs was carried out over a period of 0 days, 4 days, 7 days, 11 days, and 14 days. It can be observed that the variation of 1:5 tends to be more stable as the chart continues to experience significant improvements compared to the variation of 1:3 and 1:4. The electrochemical study was then performed by applying cyclic voltammetry from 0 V to 1.8 V. It is clearly shown that the peak of Cu oxidation is appeared at a potential of 1.2 V while the peak value of Ag oxidation is at a potential of 0.9 V.

Abstract

The people of Bolo Village, Ujung Pangkah District, Gresik Regency, choose to farm as a livelihood, both as farmers on their own land and on other people's land. Lime is a type of plant that is widely grown in the area. With a lime garden area of 450 hectares, lime farmers in this area can produce an average of 2-3 tons of lime per month per hectare. Lime from this sub-district has also reached local and international markets, such as Malaysia and Singapore. The community also develops or processes lime into processed products that have higher economic value, for example processed into processed beverage products in the form of liquids, extracts, instant powders, or processed into belt products, cosmetics and so on. On the other hand, technological developments that are rapidly developing can basically be used to increase the marketability of limes, such as processing lime peels into more useful products, not just lime contents. Nanotechnology can be used to produce lime peel powder with a nanometer size using a tool called a ball mill and grinder. The process of making lime peel nanopowder using a ball mill is very simple. This tool has also been developed a lot so the price is also cheap. For this reason, the community service activities is carried out to provide education to lime farmers in the Ujung Pangkah sub-district, Gresik to process lime peels into powder and make it possible to obtain nanopowder which has high selling value and or produces processed lime into other products. The expected output is lime peel processed products into powders of various sizes, one of which is nanometer with a lime peel powder maker, in this case a ball mill and grinder with simple operations and low prices. In simple terms, especially large powders can be used as additional ingredients for spices, even tea mixtures. This community service activity can support the 12th point of the Sustainable Development Goals in promoting zero waste, namely responsible consumption and production; as well as on point 8, namely decent work and economic growth in encouraging the formation of MSMEs to utilize processed orange peels to increase their economic value. Thus, we also believe that the community service would not only increase the lime home industry in Bolo village significantly, but also increase awareness of the community about the environmental sustainability.

Abstract

This study investigates the effects of boron concentration on boron-doped diamond (BDD) electrodes for electrochemical sensors of ciprofloxacin. The effects of boron concentration, scan rate, and pH of BDD electrodes with boron concentrations of 0.1, 0.5, and 1% were examined to determine the optimal conditions. Furthermore, square wave voltammetry (SWV) in phosphate buffer pH 7 was used to analyze the electrochemical behavior of ciprofloxacin. The results revealed a linear calibration curve in the concentration range of 30–100 μM with a recovery of 85–110%. Meanwhile, BDD electrode with the highest boron concentration in this experiment (1%) showed a very low limit of detection of 0.17 μM, meaning that 1% BDD gave a highly sensitive and significant measurement result for the electrochemical sensor of ciprofloxacin. With the results given, this study provides new insights for controlling boron concentrations in diamond electrodes for the electrochemical sensors of quinolone antibiotics.

Abstract

Levofloxacin (LEV) is a type of fluoroquinolone antibiotic that usually used for treating the bacterial infection. The released of LEV in environment may impact a significant risk to the ecosystems. Thus, a fast and sensitive sensor device is required. In this work, the detection of LEV is carried out using a screen-printed carbon electrode (SPE). The measurement methods used were square wave voltammetry and cyclic voltammetry. The limit of detection and limit quantitation were 4.34 µM, 14.4 µM, respectively. The relative standard deviation was obtained at 5.4%. The %recovery results obtained using screen printed electrode in drug, milk, and wastewater were in the range of 95-110%. The validated method was successfully applied to detect the levofloxacin and resulted in a sensitive and efficient measurement.
