Abstract

Perkembangan nanoteknologi dalam bidang kesehatan memiliki manfaat yang sangat besar, seperti ditemukaannya material penghantaran obat yang efektif, termasuk juga dalam aplikasi deteksi dini berbagai penyakit, cemaran berbahaya dalam tubuh, maupun lingkungan. Selain itu, dalam upaya pengawasan makanan, nanoteknologi berperan dalam terciptanya alat pendeteksi dini bahan tambahan makanan, yang diketahui berbahaya apabila dikonsumsi oleh manusia secara berlebih, seperti adanya zat warna yang tidak diijinkan maupun kandungan tambahan makanan yang melebihi batas toleransi. Nanosensor berbasis screen printed electrode (SPE) merupakan salah satu teknologi yang dapat digunakan untuk mewujudkan terciptanya rangkaian alat pendeteksi yang cepat, sensitif, dan portable. Pada kegiatan ini, nanoteknologi yang diterapkan pada pembuatan alat nanosensor diperkenalkan khususnya kepada analis yang ada di pusat pengawasan obat dan makanan serta dinas kesehatan, sehingga dapat meningkatkan pengetahuan tim badan pengawas obat dan makanan tentang manfaat nanoteknologi dalam pendeteksian bahan tambahan makanan. Kegiatan ini juga merupakan upaya untuk menjalin kerjasama berkelanjutan antara tim pengabdian masyarakat yang merupakan peneliti dalam bidang nanosensor dengan user di lapangan yang merupakan badan pengawas obat dan makanan, untuk mengembangkan teknologi nanosensor sesuai dengan kebutuhan di lapangan. Kegiatan ini dilaksanakan di Badan Pengawas Obat dan Makanan Surabaya, Jawa Timur. Acara dihadiri oleh 57 apoteker dan analis di lingkungan pusat pengawasan obat dan makanan, dinas kesehatan, serta instansi swasta di Surabaya. Kegiatan ini diisi dengan edukasi tentang aplikasi nanoteknologi diberbagai bidang serta demo penggunaan alat nanosensor berbasis SPE untuk mendeteksi logam berat, antibiotic, dan pewarna makanan. Sebanyak lebih dari 57% peserta menyatakaan sangat puas dengan pelaksanaan kegiatan ini. Dari kegiatan pengabdian masyarakat yang dilakukan dihasilkan artikel ilmiah dan publikasi pada media cetak/elektronik, serta video rangkaian kegiatan pengabdian masyarakat, sesuai dengan indikator kinerja utama yang ditetapkan secara nasional.

Abstract

Counter electrodes are essential in dye-sensitized solar cells (DSSCs) for facilitating charge transfer and catalyzing the regeneration of the electrolyte, impacting overall efficiency. Common counter electrode materials include platinum (Pt), poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS), and graphene, each with distinct advantages and challenges. Pt, a traditional choice, offers excellent catalytic activity but is expensive and scarce. PEDOT:PSS, a conductive polymer, is cost-effective and easily deposited but often suffers from high recombination losses and lower efficiency. Graphene, known for its high conductivity and large surface area, is emerging as a promising alternative. However, a lack of comparative studies on how different counter electrode materials influence recombination dynamics limits the understanding needed for optimizing DSSC performance. This study addresses this gap by examining Pt, graphene, and PEDOT:PSS -based counter electrodes, analyzing their effects on charge transfer, recombination behaviour, and efficiency through J-V measurements, charge extraction, and transient photocurrent (TPC) as well as transient photovoltage (TPV) analyses. Graphene-based DSSCs show superior performance, achieving the highest photocurrent density and power conversion efficiency up to 5.12% at an intensity equivalent to 1 sun (100 mWcm-2), due to enhanced charge extraction and minimized recombination. TPC data reveal that graphene supports faster charge transport, while TPV analysis shows longer electron lifetimes than PEDOT:PSS-based DSSCs. In contrast, PEDOT:PSS-based DSSCs exhibit high recombination losses, lower photocurrent, and s-shaped J-V curves, indicating high resistance of limited charge transfer efficiency. These findings highlight graphene’s potential as an optimal counter electrode material for efficient, high-performance DSSCs.

Abstract

Nanotechnology sensor is one of technology that could support biomedicine developments, including in the pharmaceutical field. Highly sensitive sensor having ability to detect various pharmaceutical substances as well as components in the food have have been developed, including the so-called nanosensor based screen printed electrode, using nanomaterial boron doped diamond (BDD). This nanosensor could replace conventional sensing technology that is considered still have several drawbacks such as inefficient routes and time consuming, as well as high cost. A nanosensor-based screen printed electrode was developed and implemented for detection of pharmaceutical substances, including drugs. In this opportunity, this community service program disseminated nanosensor technology to pharmacists and food and drug assessors at BBPOM Denpasar, Bali. The program is conducted via short course and practical case on how to use the nanosensor that already developed in the laboratory. The community service program is started with pretest about sensor and nanotechnology, followed by course, practical case, and lastly, the post-test. The post-test results showed a highly positive response, with 71% of participants reporting very high interest, 66% expressing very high satisfaction, and the majority indicating that the activity was relevant, beneficial, and worth recommending. These community service activities are expected to facilitate the broader implementation of nanosensor technology in drug and food assessments. Hopefully, this technology could be spreadly used by the the pharmacies and stake holders who have the right for doing drug and food assessements, not only in Denpasar but also in other cities in Indonesia.
