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

Abstrak Penelitian ini bertujuan untuk sintesis separator membran PVA dengan subtitusi nano partikel SiO2 (NPS) dengan metode inversi fasa sebagai aplikasi dalam baterai Li-ion. Inversi fasa merupakan metode yang digunakan untuk mengubah polimer cair menjadi lebih padat. Sintesis ini dilakukan dengan cara melarutkan PVA kemudian menambahkan SiO2 dan mencetaknya dalam wadah datar. Morfologi separator membran dapat diamati dengan karakterisasi SEM. Metode inversi fasa dapat membentuk membran separator komposit PVA/SiO2 dalam orde mikro dengan ketebalan terkecil yaitu 38,4 µm. Adanya peningkatan konsentrasi SiO2 dapat menambah ukuran pori membran separator dari 7% - 10% dan dapat meningkatkan sudut kontak dari 59,8° - 65,6°. Resistansi membran separator menurun sebesar 8,2% dan konduktivitas listrik separator semakin meningkat seiring dengan penambahan SiO2 yaitu dari 3,240 x 10-4 S/cm sampai dengan sebesar 3,530 x 10-4 S/cm. Penambahan SiO2 berbanding lurus dengan sifat tahan panas separator membran. Penambahan SiO2 NPS pada larutan PVA dengan menggunakan metode inversi fasa akan meningkatkan porositas, konduktivitas listrik, dan konduktivitas termal sehingga membran dapat di aplikasikan sebagai separator baterai Li-ion. Kata Kunci: PVA, nanopartikel (NPS), inversi fasa, separator. Abstract This research is aimed to synthesize a PVA membrane separator with nanoparticles SiO2 (NPS) substitution using phase inversion method as an application in Li-ion battery. Phase inversion is a method used to convert a liquid polymer into a solid one. This synthesis is carried out by dissolving the PVA, then adding the SiO2, and molding it in a flat container. The morphology of the membrane separator can be observed by SEM characterization. The phase inversion method can form a PVA/SiO2 composite separator membrane in a micro size with the smallest thickness of 38,468 µm. The increase of SiO2 concentration can enlarge the pore size of the separator membrane from 7% - 10% and the contact angle from 59.896° - 65.655°. The separator membrane resistance decreases by 8.2% and the electrical conductivity of the separator increase with the addition of SiO2 from 3.240 x 10-4 S/cm to 3.530 x 10-4 S/cm. The increase of SiO2 is directly proportional to the heat resistance properties of the membrane separator. The addition of SiO2 NPS to the PVA solution using the phase inversion method will raise the porosity, electrical conductivity, and thermal conductivity, so that the membrane can be applied as a Li-ion battery separator.

Sifat dasar dari nanopartikel TiO2 dijelaskna dengan baik (struktur krisal, gugus fungsi dan ukuran artikel), selanjutkan sifat, struktur, dan mekanisme transportasi muatan DSSC- juga dijelaskan dengan rinci. Bagian yang penting pada striuktur DSSC berbasis TiO2 nanopartikel ini adalah fotoanoda, katalis dan elektrolit. DSSC dengan fotoanoda TiO2 nanopartikel memiliki beberapa keunggulan, antara lain: efisiensi tinggi, biaya rendah, kestabilan tinggi, kinerja di bawah cahaya rendah, dan fleksibilitas desain. Hingga pengetahuan saya saat ini, efisiensi DSSC dengan bahan TiO2 telah mencapai lebih dari 14% dalam kondisi laboratorium. Namun, penting untuk dicatat bahwa efisiensi yang dapat diperoleh dalam praktik nyata dapat bervariasi dan masih ada tantangan dalam meningkatkan efisiensi tersebut. Pengembangan dan penelitian terus dilakukan untuk meningkatkan efisiensi DSSC dengan bahan TiO2 serta memperbaiki stabilitas dan biaya produksinya. Demikian halnya untuk DSSC dengan material TiO2-GO; memiliki kinerja tinggi dan sensitivitas yang baik, tetapi DSSC dengan TiO2 nanopartikel lebih teruji dan stabil dalam jangka panjang. Kata Kunci: Green synthesis, Dye-Sensitize solar cells, fotoanoda, Nanopartikel TiO2 Abstract This research aims to study the technique of green synthesis of nanoparticles, especially for TiO2 nanoparticles. Various types of plants can be used as a source of extraction compounds (camping agents, and deionization of Ti metal) in the synthesis of TiO2 nanoparticles, including purslane leaves (Portulaca Oleracea L.), Pisonia grandis (Leechai kottai keerai), corn (Zea mays), Kesumba Keling (bixa orellana), Kesumba seeds (Bixa orellana seed), Oranges (Citrus Limetta), Clabet (Trigonella foenum -graecum), Moringa Leaves (Moringa Oleifera L.), and Turi (Sesbania grandiflora). TiO2 nanoparticles can be applied as dye-sensitized solar cells (DSSC). The size of TiO2 nanoparticles synthesized with TPID precursors and utilizing various plant extractions has resulted in sizes of 20-100 nm (spherical-like) and crystalline sizes of 9-13 nm (tetragonal crystalline). The basic properties of TiO2 nanoparticles are well described (crystal structure, functional groups, and particle size), while the properties, structures, and charge transport mechanisms of DSSC are also described in detail. The essential parts of the DSSC structure based on TiO2 nanoparticles are the photoanode, catalyst, and electrolyte. DSSC with TiO2 nanoparticle photoanode has several advantages, including high efficiency, low cost, high stability, performance under low light, and design flexibility. The efficiency of DSSCs with TiO2 materials has reached over 14% under laboratory conditions. However, it is essential to note that the efficiencies obtained in actual practice may vary, and there are still challenges in increasing these efficiencies. Development and research continue to improve the efficiency of DSSC with TiO2 materials and the stability and production costs. Furthermore, DSSC with TiO2-GO material; has high performance and sound sensitivity, but DSSC with TiO2 nanoparticles is more tested and stable in the long term.
