Abstract

Sintesis multiferoik BiFeO3 didoping Pb telah dilakukan dengan metode Pencampuran basah (liquid mixing), menggunakan Fe murni dan Fe2O3 hasil sintesis dari pasir besi. Dalam penelitian ini digunakan variasi konsentrasi doping Pb x=0,25; x=0,5; variasi suhu kalsinasi dan variasi holding time. Sample dikarakterisasi dengan XRD (X-ray Difraction) dan magnetic susceptibility balance. Sampel variasi konsentrasi doping Pb x=0,25 ditemukan fasa pengotor BFO sekunder sedangkan sampel x=0,5 ditemukan fasa pengotor BFO sekunder dan fasa bahan penyusun. Dekomposisi fasa BiFeO3 menjadi fasa sekunder BFO meningkat dengan meningkatnya suhu kalsinasi dan holding time. Doping Pb memperbesar kemungkinan terbentuknya fasa BiFeO3. Konsentrasi doping Pb x=0,5 dapat meningkatkan prosentase fraksi volume BiFeO3 sebesar ~7% dan dapat menurunkan prosentase fraksi volume fasa BFO sekunder sebesar ~15%, namun dekomposisi fasa menjadi fasa bahan penyusun meningkat ~43%. Ukuran kristal BiFeO3 sebesar ~29 nm sampai ~112 nm. Sampel memiliki nilai χ berkisar 1,69x10-7.

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

Rooftop photovoltaic (PV) plant is one ot the independent electricity that us favorable in recent year. Rooftop PV plant can be used as the source of smart building as well as fast charging station. Although rooftop PV plant could provide clean and sustainable energy from solar, they also come with disadvantages in term of intermittent power output. This intermittent power output is due to the uncertainty of the source. To tackle this problem, maximum power point tracking method is essential. Maximum power point tracking (MPPT) method can be used to extract maximum power from the solar cell in all conditions. This paper proposes an intelligent method for designing DC-DC MPPT based on fruit fly optimization (FFO) on realistic rooftop PV plant. Practical rooftop PV plant in Universitas Airlangga is employed as the testing system. The proposed method's efficacy is evaluated using time domain simulation. According to the simulation results, the proposed method can significantly extract power from PV.

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

Cocrystal of p-Methoxycinnamate acid-succinic acid has been produced by microwave irradiation and solvent evaporation methods. Cocrystals are formed using succinic acid as the coformer at a molar ratio of 1:1. The formation of cocrystal can be done by solvent evaporation method and microwave radiation method. Physicochemical properties have been studied by FT-IR, DSC, PXRD, and SEM analysis. The solubility test was carried out with pH 6.8 phosphate buffer at a temperature of 25±0.5°C for 5 hours and the dissolution test was carried out with 900 mL pH 6.8 phosphate buffer at a temperature of 37±0.5°C with the speed of 75 rpm using a paddle-type dissolution test apparatus. The solubility of PMCA has increased its solubility in cocrystals by the solvent evaporation method by 1.19 times and by the microwave radiation method by 1.16 times compared to PMCA. The dissolution rate of the cocrystals of the solvent evaporation method increased by 3.50 times and the cocrystals of the microwave radiation method increased by 2.29 times compared to PMCA.

Abstract

The most common problem in spark ignition engine is how to increase the speed performance. Commonly researchers used traditional mathematical approaches for designing speed controller of spark ignition engine. However, this solution may not be sufficient. Hence, it is important to design the speed controller using smart methods. This paper proposes a method for designing speed controller of a spark ignition engine using the bat algorithm (BA). The simulation is carried out using the MATLAB/SIMULINK environment. Time domain simulation is carried out to investigate the efficacy of the proposed method. From the simulation results, it is found that by designing speed controller of spark ignition engine using PI based bat algorithm, the speed performance of spark ignition engine can be enhanced both in no load condition and load condition compared to conventional PI controler.

Abstract

The development of nanotechnology in the world is very rapid, and the applications of nanotechnology can be felt in various fields in everyday life. For instance, to control food, nanotechnology plays a role in creating early detection tools for food additives, which are known to be dangerous if consumed by humans in excess, such as the presence of colorants that are not permitted or food additives that exceed tolerance limits. Nanosensors based on screen print electrodes (SPE) are devices that can be used for detection with various notable properties such as fast, sensitive and portable. Seeing the importance of developing and down streaming nanotechnology to society, education regarding the role of nanotechnology needs to be carried out. In this activity, nanotechnology applied in the manufacture of nanosensor devices was introduced, especially to analysts at the drug and food control center and the health service. Apart from that, through this activity, sustainable collaboration can be established between the community service team who are researchers in the field of nanosensors and users in the field who are drug and food regulatory bodies, to develop nanosensor technology according to needs in the field. This activity will be carried out in Pontianak, West Kalimantan, specifically aimed at pharmacists and analysts in the drug and food control center, health service, and industry and trade service (Disperindag). This activity will include education about nanotechnology applications in various fields as well as a demonstration on the use of SPE-based naosensor devices. From this event, in future the analyst may do the analysis in field without waiting long time analysis in laboratory. From this community service activities, scientific articles and publications can be produced in print/electronic media, as well as videos of community service activities, in accordance with the main performance indicators determined nationally.

Abstract

Ferulic acid-nicotinamide cocrystals have been successfully synthesized using the solvent evaporation method. In this case, nicotinamide which acts as a coformer is mixed with ferulic acid with a 1:1 molar ratio via dissolving process in ethanol. The obtained cocrystals were characterized through Differential Scanning Calorimetric (DSC), Powder X-Ray Diffraction (PXRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and computational analyses. The DSC characterization revealed distinct endothermic peaks at 99.5°C and 128.5°C with a W-shaped profile. This result is different from the thermal behavior of pure ferulic acid which indicates that the ferulic acid-nicotinamide cocrystal is successfully formed. This result is also supported by the PXRD result which reveals distinct peaks at 5.24°, 16.31°, and 34.69° belong to crystal deformation of ferulic acid cocrystal due to the coexistence of nicotinamide coformer. The FTIR data also further indicate the formation of cocrystals marked by the disappearance of the NH(v) functional group at 3400 cm−1 and the emergence of a fuse-like peak at around 1600 cm−1 corresponding to the C-O(v) and NH() functional groups. SEM analysis also demonstrated morphological differences between the obtained cocrystal with pure ferulic acid crystals. The pure ferulic acid crystals exhibit a rectangular shape, whereas the cocrystals display a sword-like morphology. The phenomenon of cocrystal formation was also studied using computational studies through Density Functional Theory (DFT) and Quantum Theory of Atoms in Molecules (QTAIM) which confirmed that the cocrystals were stabilized through intermolecular hydrogen bonding.
