Abstract

Abstrak PANi merupakan polimer konduktif yang mudah disintesis, memiliki konduktivitas tinggi, dan mampu menghambat pergerakan ion-ion elektrolit yang bersifat merusak. SiO2 merupakan bahan keramik anorganik dengan stabilitas termal tinggi dan isolator listrik yang baik. Paduan kedua material ini, membentuk PANi/SiO2 yang terbukti efektif dalam meningkatkan ketahanan korosi, terutama pada permukaan logam PANi disintesis melalui reaksi polimerisasi oksidasi, sedangkan pembuatan PANi/SiO2 menggunakan metode pencampuran basah (wet mixing). PANi/SiO2 dilapiskan pada substrat baja SS 304 menggunakan metode dip coating. Pelapisan dilakukan dengan variasi konsentrasi PANi/SiO2 yang telah ditentukan sebelumnya, dengan tujuan agar mendapatkan komposisi optimal dan ketahanan korosi yang maksimal. PANi/SiO2 dikarakterisasi menggunakan FTIR, XRD, dan SEM. Laju korosi diperoleh dengan uji korosi menggunakan potensiostat. Hasil uji korosi menunjukkan bahwa konsentrasi 5,5% memberikan penurunan laju korosi terbaik dibandingkan variasi konsentrasi lainnya, yaitu sebesar 0,63 x 10-3 mm/year. Konsentrasi ini mampu membentuk lapisan pelindung yang optimal dengan distribusi partikel SiO2 yang merata serta jaringan konduktif PANi yang efektif menghambat penetrasi ion-ion agresif. Abstract PANi is a conductive polymer that is easy to synthesize, possesses high electrical conductivity, and is capable of inhibiting the movement of destructive electrolyte ions. SiO2 is an inorganic ceramic material with high thermal stability and excellent electrical insulation properties. The combination of these two materials forms a PANi/SiO2 composite, which has been proven effective in enhancing corrosion resistance, particularly on metal surfaces. PANi is synthesized through oxidative polymerization, while the PANi/SiO2 composite is prepared using the wet mixing method. The composite is applied to SS 304 stainless steel substrates using the dip coating technique. The coating process was carried out with various predetermined concentrations of PANi/SiO2, aiming to obtain the optimal composition and maximum corrosion resistance. The PANi/SiO2 composite was characterized using FTIR, XRD, and SEM. Corrosion rate was measured through electrochemical corrosion testing using a potentiostat. The results showed that the 5,5% concentration yielded the best reduction in corrosion rate compared to other variations, with a value of 0,63 x 10-3 mm/year. This concentration successfully formed an optimal protective layer, characterized by a uniform distribution of SiO2 particles and a conductive PANi network that effectively inhibits the penetration of aggressive ions.

Abstract

This community service program aimed to improve knowledge, perceptions, and behaviors of the Indonesian diaspora at the Sungai Mulia Learning Studio (SBSM) in Kuala Lumpur, Malaysia, regarding the use of traditional spices for health. The program involved counseling, demonstrations, and completion of an evaluation questionnaire using a Likert scale and open-ended questions. Twenty-three participants took part in the activities and evaluations. The results showed high levels of knowledge and positive perceptions, especially in participants’ belief in the health benefits of traditional spices and their understanding of the functions of basic spices such as ginger and turmeric, commonly used as traditional medicines. Although some participants still chose modern medicine as their main option, they demonstrated a positive attitude toward herbal remedies. Behavioral analysis indicated a strong tendency to prepare, consume, and seek information about spices after attending the program. Qualitative findings supported these results; most participants stated that the activities were beneficial, broadened their insight, and encouraged habit changes toward greater use of herbal medicine. All participants also expressed willingness to join follow-up programs. Overall, this program effectively improved spice-based health literacy and has the potential to be scaled up through more intensive practical sessions and provision of guidance materials.

Abstract

This community service program was designed to integrate fundamental physics concepts into practical learning through the implementation of smart robot projects, aiming to enhance students’ comprehension and interest in physics. Conducted at SMAN 3 Pamekasan, Madura, the program involved the design, assembly, and functional testing of four line follower robots and one water-based fire extinguisher robot. Preparatory stages included intensive prototyping and coding trials at the Electronics Laboratory, Department of Physics, Universitas Airlangga, followed by a field survey to the school to assess readiness and requirements. The main activity engaged students in hands-on tasks, encompassing mechanical assembly, electronic circuit integration, and programming, thereby enabling them to directly observe the application of physics principles in robotics. Evaluation using pre-test and post-test instruments indicated a measurable improvement in understanding, with average scores rising from 6.83 to 7.42. These results demonstrate the effectiveness of project-based learning in fostering not only cognitive gains but also positive attitudes toward physics by reframing it as an applied and engaging discipline rather than purely theoretical.

Abstract

Kecamatan Gandusari, Kabupaten Trenggalek, merupakan salah satu sentra produksi kedelai yang memiliki potensi besar dalam mendukung pemenuhan kebutuhan protein masyarakat. Namun, pengolahan kedelai oleh UMKM tahu setempat masih menghadapi sejumlah kendala, terutama keterbatasan variasi produk dan pemasaran yang masih dilakukan secara konvensional, sehingga nilai jual dan jangkauan pasar produk belum optimal. Kegiatan Pengabdian kepada Masyarakat ini dilaksanakan untuk membantu UMKM meningkatkan nilai tambah dan daya saing melalui inovasi produk serta pendampingan digitalisasi pemasaran. Kegiatan diawali dengan observasi dan identifikasi permasalahan mitra, dilanjutkan dengan penyuluhan, pelatihan praktik pembuatan tahu sutera, pendampingan pemasaran digital, serta evaluasi dampak kegiatan. Pelatihan difokuskan pada penguasaan teknik pembuatan tahu sutera dengan tekstur lebih lembut dan cita rasa yang lebih baik, disertai penerapan higiene dasar dan pengemasan sederhana. Pada aspek pemasaran, mitra didampingi memanfaatkan media sosial dan aplikasi pesan instan untuk promosi, penyusunan katalog produk, dan pengelolaan pemesanan. Hasil kegiatan menunjukkan adanya perubahan positif pada praktik usaha mitra, ditandai dengan kemampuan memproduksi tahu sutera sebagai produk bernilai tambah, penggunaan kemasan dan label yang lebih informatif, serta mulai aktifnya kanal pemasaran digital. Selain memberikan dampak awal terhadap peningkatan kompetensi produksi dan pemasaran UMKM tahu, kegiatan ini juga mendukung pencapaian Tujuan Pembangunan Berkelanjutan (SDGs), khususnya SDGs No. 1 (No Poverty), SDGs No. 2 (Zero Hunger), dan SDGs No. 3 (Good Health and Well-being). Kegiatan ini berpotensi memperkuat keberlanjutan usaha dan meningkatkan kesejahteraan pelaku UMKM secara bertahap. Tofu MSME Product Innovation in Gandusari District, Trenggalek Regency Through Digital Marketing Training and Mentoring  Abstract Gandusari District in Trenggalek Regency is a soybean production center with the potential to meet the community's protein needs. However, the utilization of soybeans by tofu Micro, Small, and Medium Enterprises (MSMEs) still faces limitations, particularly in product variation and conventional marketing, resulting in relatively low market reach and selling value. This Community Service (PKM) activity aims to increase the added value and competitiveness of tofu MSMEs through product innovation training in making silk tofu (tahu sutera) and digital marketing assistance. The implementation methods included observation and problem identification, program planning, counseling, practical training and mentoring, and impact evaluation. Product innovation training focused on mastering the techniques of producing seasoned silk tofu with a soft texture and improved flavor, accompanied by the application of basic hygiene and simple packaging. Digital marketing assistance was conducted by optimizing social media and instant messaging applications for promotion, product catalogs, and ordering. The results showed a significant increase in the partner's understanding and skills in producing silk tofu and managing digital marketing channels. This activity has successfully opened up new market opportunities and increased the economic value of the partner's tofu products.
