Abstract

Bangil adalah salah satu kecamatan yang ada di Pasuruan sekaligus sebagai ibukota Kabupaten. Secara Geografis, letak Kecamatan Bangil merupakan daerah paling utara di Kabupaten Pasuruan. Pemanfaatan lahan pertanian di bangil tidak hanya digunakan untuk menanam padi, tetapi jenis tanaman dan jenis ikan air tawar bisa menjadi alternatif sebagai pemanfaatan lahan yang ada di wilayah Bangil. Menurut Badan Statistik pada tahun 2021 hasil produksi padi mengalami penurunan sebesar 0,43%. Penurunan produksi pertanian terutama di daerah bangil kelurahan Manarwi terjadi akibat kurangnya pemerataan ketersediaan air dan mengandalkan ketersediaan air di musim hujan saja. Untuk itu agar pemerataan air tercukupi dengan baik, perlu adanya alat alternatif sebagai penyalur ketersediaan kebutuhan air. Pompa air berbasis energi terbarukan bisa menjadi salah satu alternatif untuk mengatasi hal tersebut. Dengan konsep pompa air yang ramah lingkungan, mudah dibuat dan di aplikasikan, tidak membutuhkan bahan bakar atau peralatan elektronik menjadi alternatif baru dan memberikan keuntungan dalam menekan pengeluaran dan tergolong sebagai alat yang murah serta bisa digunakan dalam jangka waktu yang lama. Hal ini mendorong tim PKM untuk memberikan pengarahan dan pembuatan pompa air berbasis free energy kepada masyarakat di wilayah Manarwi. Komponene masyarakat diajak untuk terlibat dalam pembuatan dan pemanfaatan pompa air berbasis free energi ini, meliputi pemerintahan tingakat desa, dan masayarakat di wilayah manarwi. Tahapan pelatihan dan pembuatan Pompa free energy ini meliputi pengetahuan tentang free energy water pump, menjelaskan prinsip kerja free energy water pump, pembuatan free energy water pump, dan menjelaskan serta pengaplikasian free energy water pump dalam bidang pertanian. Keberhasilan pelatihan ini dievaluasi baik pelaksanaannya maupun hasilnya. Evaluasi tersebut dilakukan dengan menggunakan angket respon peserta pelatihan terhadap pelaksanaan kegiatan pelatihan. Hasil angket respon adalah sebagai berikut : terhadap perlunya kegiatan PKM ini sebesar 85%, wawasan system kerja water pump 85%, wawasan tentang prinsip gaya gravitasi pada sistem water pump 82,5%, kegiatan diskusi 80%, pembuatan alat 90%, dan perlunya perkembangan alat 92,5%. The Implementation of Making a Free Energy Water Pump to Improve the Availability of Water Needs on Agricultural Land for the Community of Manarwi Bangil Pasuruan Village Bangil is one of the sub-districts in Pasuruan, which is also the district capital. Geographically, the location of Bangil District is the northernmost area in Pasuruan Regency. The utilization of agricultural land in Bangil is not only used for planting rice, but types of plants and freshwater fish can be an alternative for land use in the Bangil area. According to the Statistics Agency, in 2021, rice production will decrease by 0.43%. The decline in agricultural production, especially in the Bangil area of ??the Manarwi sub-district, occurred due to the lack of equal distribution of water availability and reliance only on water availability in the rainy season.For this reason, so that water distribution is fulfilled correctly, it is necessary to have an alternative tool as a distributor of the availability of water needs. Renewable energy-based water pumps can be an alternative to overcome this. With the concept of a water pump that is environmentally friendly, easy to make and apply, and does not require fuel or electronic equipment, it is a new alternative. It provides the advantage of reducing expenses, is classified as a cheap tool, and can be used for a long time. This prompted the PKM team to give directions and manufacture water pumps based on free energy for the people in the Manarwi area. Community components are invited to be involved in the manufacture and use of this free energy-based water pump, including village-level government and the community in the Manarwi area. The stages of training and making this free energy pump include knowledge, explaining the working principles, making free energy water pumps, and explaining and applying free energy water pumps in agriculture. The success of this training is evaluated both in its implementation and results. The evaluation was carried out using a questionnaire from the training participants' responses to the performance of the training activities. The results of the response questionnaire are as follows: regarding the need for this PKM activity by, 85%, insight into the working system of the water pump 85%, insight into the principle of gravitational force in the water pump system 82.5%, discussion activities 80%, tool making 90%, and the need for tool development 92.5%.

Abstract

The subject of electromagnetic fields is widespread today, including in the medical world. One of them is therapy in fracture healing using the Pulsed Electromagnetic Field (PEMF) method by utilizing a magnetic field. Fracture healing using the magnetic field method utilizes the Helmholtz coil, which is influenced by the current and the amount of turns flowing in the magnetic field. This study conducted a literature study on fracture healing using the PEMF and the LMHFV methods. A comparison of these two methods will show different healing effects. From the studies, we can conclude which way has the most advantage in healing. A faster rehabilitation process will have an impact on reducing implant failure. In contrast, Applying the LMHFV method to bone fractures gives more significant and faster results in bone formation in the damaged part, and the healing process is owned faster. From these two methods, it can be concluded that the LMHFV method provides a similar healing effect than the PEMF method. Applying the LMHFV and PEMF method to bone fractures gives more significant and faster results in bone formation in the damaged part. In addition, the healing process is owned faster.

Abstract

The increasing volume of household waste in densely populated residential areas is a major challenge for urban environmental management. Limited waste management systems and low household-level waste-sorting practices lead to the accumulation of organic waste, which could cause environmental pollution. Therefore, a sustainable waste management strategy based on community participation is needed. This community service program aims to implement and evaluate a zero-waste strategy by empowering the PKK Ecomitra group in Wage Village, Sidoarjo, through the use of appropriate technologies, including a Dekomposer Dua Sisi (Dedisi) and biopore holes, for processing household organic waste. The program was implemented using a Participatory Action Research (PAR) approach that actively involved partners in planning, socialization, training, technology application, and evaluation. Evaluation was conducted through pretest and posttest methods on 15 indicators of participant knowledge and attitudes. The results showed a significant increase in understanding of the fermentation process, waste sorting skills, awareness of the zero-waste concept, and the use of biopore holes. The overall program achievement rate exceeded 80 percent of the set target. These results indicate that a zero-waste strategy based on collective community decisions and the application of simple technologies is effective in increasing household waste management capacity and behavior, and in supporting the achievement of SDGs 12 and 13.

Abstract

Abstrak Polianilin (PANI) merupakan salah satu polimer konduktif yang banyak diteliti sebagai material sensor pH karena sifat konduktivitasnya yang bergantung pada jumlah ion hidrogen (H⁺) di lingkungannya. Meskipun aplikasinya terus berkembang dalam bidang lingkungan, biomedis, dan teknologi fleksibel, belum ada kajian bibliometrik komprehensif yang memetakan arah dan relevansi ilmiahnya secara global. Penelitian ini bertujuan untuk menjawab: (1) bagaimana tren jumlah sitasi dari penelitian terkait sensor pH berbasis polianilin dan artikel mana yang paling berpengaruh dalam bidang tersebut, (2) apakah studi Polyaniline (PANI) sebagai sensor pH tetap menjadi topik yang relevan untuk penelitian akademis di masa depan, serta (3) bagaimana upaya penelitian saat ini didistribusikan mengenai sensor pH berbasis Polianilin dalam hal jejaring kolaborasi penulis dan peta topik penelitian berdasarkan kata kunci. Analisis dilakukan menggunakan basis data Dimensions dengan pendekatan Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) dan pemetaan visual melalui VOSviewer. Hasil menunjukkan peningkatan signifikan penelitian sensor pH berbasis PANI pada periode 2016–2019, diikuti fluktuasi hingga 2025. Meski publikasi menurun setelah 2019, tren sitasi terus meningkat, menandakan keberlanjutan relevansi akademis topik ini. Pemetaan kolaborasi mengidentifikasi klaster riset utama di Asia dan Eropa dengan pergeseran fokus dari sensor optik menuju integrasi nanokomposit dan sistem berbasis IoT. Temuan ini menegaskan meskipun laju publikasi menurun, topik ini tetap memiliki posisi strategis dalam riset material fungsional. Pengembangan masa depan berpotensi difokuskan pada peningkatan sensitivitas, stabilitas jangka panjang, integrasi dengan teknologi nirkabel dan perangkat pintar untuk mendukung sistem pemantauan lingkungan dan biomedis berkelanjutan.   Abstract  Polyaniline (PANI) is one of the most widely studied conducting polymer for pH sensing applications due to its conductivity, which depends on the concentration of hydrogen ions (H⁺) in its environment. Although its applications continue to expand in environmental monitoring, biomedical systems, and flexible technologies, no comprehensive bibliometric study has yet mapped its global scientific relevance and research trajectory. This study aims to address: (1) how citation trends of studies on polyaniline-based pH sensors have evolved and which articles have been the most influential in the field, (2) whether research on Polyaniline (PANI) as a pH sensor remains a relevant topic for future academic investigation, and (3) how current research efforts on PANI-based pH sensors are distributed in terms of author collaboration networks and keyword-based topic mapping. The analysis was conducted using the Dimensions database, applying the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach and visual mapping through VOSviewer. Results reveal a significant increase in PANI-based pH sensor research during 2016–2019, followed by fluctuations up to 2025. Although publication output declined after 2019, citation trends continued to rise, indicating the sustained academic relevance of this topic. Collaboration network mapping identified major research clusters in Asia and Europe, with thematic shifts from optical sensors toward nanocomposite integration and IoT-based systems. These findings confirm that despite the decline in publication rate, this topic remains strategically positioned within functional material research. Future directions are expected to focus on improving sensitivity, long-term stability, and integration with wireless and smart technologies to support sustainable environmental and biomedical monitoring systems.

Abstract

Abstrak Peningkatan kebutuhan energi listrik di Indonesia mendorong pengembangan teknologi energi terbarukan, termasuk Dye-Sensitized Solar Cell (DSSC). Penelitian ini bertujuan mensintesis dan mengkarakterisasi material TiO₂–Cu menggunakan metode green synthesis berbasis ekstrak kulit jeruk (Citrus sinensis) sebagai agen pereduksi alami. Proses sintesis meliputi preparasi ekstrak kulit jeruk, pembentukan TiO₂ nanopartikel melalui reaksi TTIP–ekstrak, komposit Cu, serta kalsinasi pada 500°C. Karakterisasi FTIR menunjukkan pita serapan khas Ti–O dan Ti–O–Ti pada rentang 426–569 cm⁻¹, serta gugus –OH dan sisa biomolekul organik yang menegaskan keberhasilan sintesis hijau. Analisis UV-Vis menghasilkan nilai band gap TiO₂ sebesar 4,1 eV, menunjukkan karakter semikonduktor anatase dengan respons optik dominan pada wilayah ultraviolet. Uji performa DSSC yang difabrikasi menggunakan komposit TiO₂–Cu dan dye alami daun ketapang menghasilkan nilai open-circuit voltage (Voc) sebesar 0,479 V, short-circuit current (Isc) 0,02 mA, dan efisiensi konversi energi 0,00426%. Hasil ini mengonfirmasi bahwa ekstrak kulit jeruk berperan sebagai bioreduktor efektif dalam pembentukan TiO₂–Cu, namun performa fotovoltaik masih rendah sehingga diperlukan optimasi lanjutan terkait morfologi, struktur pita energi, dan kompatibilitas dye. Penelitian ini menunjukkan potensi pemanfaatan limbah biomassa sebagai prekursor ramah lingkungan dalam pengembangan fotoanoda DSSC berbasis energi hijau. Kata Kunci: TiO₂–Cu, green synthesis, kulit jeruk, DSSC, fotoanoda Abstract The increasing demand for electrical energy in Indonesia highlights the need for the development of renewable technologies such as Dye-Sensitized Solar Cells (DSSC). This study aims to synthesize and characterize TiO₂–Cu materials using a green synthesis approach employing orange peel extract (Citrus sinensis) as a natural reducing agent. The synthesis process involved extract preparation, TiO₂ nanoparticle formation via TTIP–extract reaction, Cu incorporation, and calcination at 500°C. FTIR characterization confirmed the formation of Ti–O and Ti–O–Ti bonding at 426–569 cm⁻¹, accompanied by –OH groups and residual organic biomolecules, indicating the successful formation of TiO₂ via a green route. UV-Vis analysis showed a band gap of 4.1 eV, consistent with anatase-type semiconductors with dominant UV absorption. DSSC performance testing using TiO₂–Cu composite photoanodes and natural ketapang leaf dye yielded an open-circuit voltage (Voc) of 0,479 V, a short-circuit current (Isc) of 0,02 mA, and a power conversion efficiency of 0.00426%. These results demonstrate that orange peel extract functions effectively as a bioreducing agent for TiO₂–Cu formation; however, the photovoltaic performance remains low, requiring further optimization of morphology, electronic structure, and dye compatibility. Overall, this study highlights the potential of biomass waste as an eco-friendly precursor for developing green-based DSSC photoanodes. Keywords: TiO₂–Cu, green synthesis, orange peel extract, DSSC, photoanode

Abstract

Graphene oxide is a two-dimensional substance that shares the same structure as graphene and can be produced using several methods. The difficulty for green technology lies in developing a cost-effective and efficient method to produce graphene and graphene oxide without relying on chemical processes. A highly sustainable technology involves the use of a laser diode, which is both cost-effective and environmentally friendly. This technique produces a material known as laser-induced graphene/graphene oxide (LIG/LIGO). From a commercial standpoint, the laser diode is typically purchased without an electronic stabilizer component. Nevertheless, laser stability is crucial for the production process of LIG/LIGO. The objective of our study is to examine the impact of laser current management on the production of graphene on a polyimide (PI) sheet utilizing a 450 nm diode laser. The laser controller we utilize is the National Instruments (NI) PXIe-1085 device. The optical power of the laser diode was measured between 0.21 and 0.79 W. After the laser current was stabilized, the power slightly shifted, ranging from 0.18 to 0.86 W. Both experiments were conducted with a current range of 0.3 to 1 A. Before regulation, the laser diode experiences current fluctuations in the range of around 0.01 to 0.03 A. The study findings highlight the significance of laser current management in manufacturing LIG/LIGO by ensuring a consistent and precise laser power output, hence minimizing flaws in the final product. However, the analysis reveals that graphene oxide is the predominant yield in this characterization. This fact is caused by the presence of a graphene layer not exposed to the surface during measurement. This approach provides several benefits, such as the capacity to produce graphene/GO in a targeted, non-chemical, and fast manner, as well as its potential for diverse applications.
