Abstract

Program Pengabdian kepada Masyarakat (PKM) ini bertujuan untuk mengoptimalkan potensi pariwisata Desa Lintong Nihuta melalui strategi branding dan kolaborasi komunitas. Kegiatan dilaksanakan dengan pendekatan partisipatif yang meliputi sosialisasi, pelatihan, pendampingan, dan evaluasi. Hasil observasi awal menunjukkan bahwa masyarakat desa memiliki potensi wisata alam dan budaya yang menarik, namun belum diiringi dengan kemampuan branding dan pemasaran digital yang memadai. Melalui pelatihan berbasis learning by doing, terjadi peningkatan pemahaman peserta terhadap konsep identitas merek, pemasaran digital, dan pengelolaan konten promosi, yang dibuktikan dengan peningkatan skor rata-rata dari 45% menjadi 85%. Implementasi branding juga menghasilkan konsistensi identitas visual, peluncuran produk baru, dan paket wisata tematik yang meningkatkan daya tarik destinasi. Jumlah pengunjung meningkat dari sekitar 50 menjadi 150 orang per bulan, berdampak pada peningkatan pendapatan pelaku wisata lokal lebih dari dua kali lipat. Selain itu, terbentuknya forum kolaboratif desa wisata memperkuat kelembagaan dan keberlanjutan program pascapendampingan. Meskipun masih dihadapkan pada keterbatasan infrastruktur dan literasi digital, kegiatan ini menunjukkan bahwa strategi branding berbasis komunitas mampu menjadi instrumen efektif dalam memperkuat daya saing dan keberlanjutan pariwisata desa.

Abstract

Permukiman padat penduduk di Kota Medan menghadapi permasalahan rendahnya kualitas air tanah akibat kontaminasi mikrobiologis serta tingginya volume sampah yang tidak terkelola. Kegiatan pengabdian ini bertujuan mengimplementasikan teknologi filtrasi air tepat guna dan manajemen zero waste secara terpadu menggunakan pendekatan Participatory Action Research (PAR). Program dilaksanakan melalui empat tahap: identifikasi masalah, persiapan prototipe filtrasi bertingkat (pasir silika, arang aktif, zeolit) dan modul pelatihan zero waste, pelaksanaan berupa pemasangan unit filtrasi komunal serta pelatihan pemilahan sampah dan pengomposan, dan evaluasi berbasis analisis pre-post test. Hasil menunjukkan sistem filtrasi menurunkan kekeruhan air sebesar 85–88% dan mengeliminasi kontaminasi E. coli pada 89% sampel. Program zero waste menurunkan volume timbulan sampah sebesar 25–32% dalam tiga bulan. Skor pengetahuan masyarakat meningkat dari 45% menjadi 78%, dan skor praktik dari 38% menjadi 72%. Kegiatan ini membuktikan bahwa pendekatan integratif filtrasi air dan zero waste berbasis partisipasi komunitas merupakan model intervensi yang efektif dan layak direplikasi di kawasan permukiman padat perkotaan.

Abstract

Access to clean water in Indonesia's remote coastal areas requires a self-sufficient and sustainable desalination solution. This study aims to optimize a prototype of a non-invasive solar desalination system by integrating Photovoltaic-Thermoelectric (PV-TE) hybrid technology for off-grid clean water production. A pilot-scale unit was developed from a basic passive solar distillation prototype through the addition of photovoltaic panels and thermoelectric modules that double as waste heat recoverers and active condenser coolers. Test results show significant performance improvements, with conductivity removal efficiency reaching 99.83% with ultra-pure water quality (80 µS/cm). Water productivity increased exponentially by 1148%, from 0.50 L/day.m² in the basic prototype to 6.24 L/day.m² in the hybrid system, with a system energy conversion efficiency reaching 29.05%. These findings confirm that the strategic integration of PV-TE components not only overcomes productivity limitations in passive solar desalination but also offers an autonomous desalination solution with low environmental impact. This research contributes to the development of self-sufficient water infrastructure that can be replicated in coastal communities with abundant solar intensity.

Abstract

The depletion of fossil fuels and strict emissions regulations have driven the need for renewable additives that can improve diesel combustion while reducing pollutants. This study experimentally examined the combustion characteristics and exhaust emissions of diesel fuel mixed with cinnamon oil and basil oil as dual additives in a single-cylinder stationary diesel engine. The essential oils were mixed into the diesel fuel at concentrations of 5%, 10%, and 15%, either individually or in combination, and tested at 1500 rpm with load variations of 0-100%. The results showed that the 10% dual additive mixture (DCB10) provided the best performance with a reduction in CO and HC emissions of 40.9% and 32.1%, respectively, compared to pure diesel fuel. However, NOx emissions increased by 8.5% due to high combustion temperatures and oxygen availability. The synergistic effects of the low viscosity of cinnamon oil and the antioxidant properties of basil oil improved atomization and oxidation kinetics, resulting in more complete combustion. Despite the increase in NOx, the environmental benefits remain positive, making the dual essential oil blend a promising bio-additive for cleaner diesel operation.

Abstract

Keterbatasan akses air tawar di wilayah pesisir akibat tekanan antropogenik dan perubahan iklim menuntut inovasi teknologi desalinasi yang berkelanjutan. Penelitian ini bertujuan untuk melakukan optimalisasi prototipe desalinasi non-invasif tenaga surya dengan menerapkan Sistem Desalinasi Hibrida (Fotovoltaik-Termoelektrik) guna memenuhi kebutuhan produksi air bersih secara off-grid. Melalui desain modular yang mengedepankan skalabilitas dan kemudahan instalasi, studi ini mengevaluasi peningkatan kinerja dari prototipe awal menuju unit skala pilot yang dioptimalkan. Hasil penelitian menunjukkan bahwa kedua sistem mencapai efisiensi penghilangan konduktivitas hingga $>99\%$, yang menjamin kualitas air bersih secara konsisten antar musim. Implementasi teknologi hibrida pada unit skala pilot berhasil meningkatkan produktivitas secara signifikan dari 0,45 L/hari.m² menjadi 6 L/hari.m² pada periode radiasi matahari puncak. Temuan ini mengonfirmasi bahwa integrasi komponen fotovoltaik-termoelektrik tidak hanya meningkatkan efisiensi konversi energi matahari secara substansial, tetapi juga menawarkan solusi desalinasi yang non-invasif bagi ekosistem pesisir. Penulisan ini memberikan kontribusi pada pengembangan infrastruktur air mandiri di wilayah dengan intensitas cahaya matahari melimpah, sekaligus membuka peluang riset lanjutan pada penggunaan material penyerap inovatif dan sistem kontrol operasional yang adaptif.

Abstract

The depletion of fossil fuels and stringent emission regulations demand renewable additives that enhance diesel combustion while reducing pollutants. This study experimentally investigates the combustion characteristics and exhaust emissions of diesel blended with cinnamon oil and basil oil as dual additives in a single-cylinder stationary diesel engine. Essential oils were mixed with diesel at 5%, 10%, and 15%, either singly or in combination, and tested at 1500 rpm under varying loads (0–100%). Results showed that the dual additive blend at 10% (DCB10) yielded the best performance, reducing CO and HC emissions by up to 40.9% and 32.1%, respectively, compared to neat diesel. However, NOx emissions increased by 8.5% due to higher combustion temperatures and oxygen availability. The synergistic effect of cinnamon oil's low viscosity and basil oil's antioxidant properties improved atomization and oxidation kinetics, leading to more complete combustion. Despite the NOx trade-off, the net environmental benefit is positive, positioning dual essential oil blends as promising bio-additives for cleaner diesel operation.

Abstract

The increasing amount of aluminum can waste has encouraged the development of a faster and more efficient processing system. This research focuses on the analysis of kinematic and dynamic performance of a pneumatic-based can pressing machine equipped with a forward–reverse motion mechanism. The study was conducted through machine design, fabrication, assembly, and experimental testing. The developed system used an SC 80 × 175 mm double-acting pneumatic cylinder with a working pressure of 6 bar, operated using a 5/2 solenoid valve. Experimental results showed that the actuator produced a pressing force of 3014.4 N, allowing the machine to perform stable linear movement during the pressing process. Testing on ten aluminum cans showed that the average processing time was reduced from 78 seconds in the manual process to 24 seconds using the pneumatic system. This improvement resulted in a time efficiency increase of 69.23%. These findings indicate that the developed pneumatic can press machine provides better productivity and performance for aluminum waste processing.
