Abstract

Kegiatan pengabdian masyarakat ini bertujuan untuk memberdayakan Kelompok Tani "Qila Tani" di Desa Karya Indah, Kampar, melalui implementasi teknologi tepat guna berupa trolley sprayer pestisida mekanis. Program dilatarbelakangi oleh rendahnya efisiensi kerja penggunaan knapsack sprayer manual 16 liter, yang menyebabkan tingginya beban fisik dan lambatnya pengendalian hama. Metode pelaksanaan meliputi identifikasi masalah, pelatihan teknis operasional dan perawatan (SOP), serta hibah alat. Pelatihan diikuti secara intensif oleh 7 orang peserta, mewakili 70% dari total anggota kelompok tani. Hasil evaluasi kuantitatif menunjukkan keberhasilan program yang signifikan dalam peningkatan kapasitas Sumber Daya Manusia (SDM). Rata-rata global kompetensi peserta meningkat sebesar 72%. Lonjakan tertinggi terjadi pada keterampilan operasional alat sebesar 92%, diikuti peningkatan pemahaman perawatan dan SOP sebesar 74%, serta prinsip kerja mesin sebesar 53%. Selain itu, secara teknis tercatat peningkatan kapasitas angkut pestisida hingga 70 liter dan percepatan waktu penyemprotan. Kesimpulannya, adopsi trolley sprayer terbukti efektif meningkatkan kompetensi SDM petani, menghilangkan beban kerja fisik, dan mempercepat transisi mekanisasi pertanian untuk mendukung produktivitas di Desa Karya Indah.

Abstract

Penelitian ini memodelkan dan menganalisis aliran lapisan batas dan perpindahan panas nanofluida berbasis nano-encapsulated phase change material power-law (NEPCMPL) pada permukaan pelat yang meregang kontinu dengan suhu permukaan bervariasi. Model matematis dikembangkan menggunakan pendekatan hukum daya untuk menggambarkan karakteristik fluida non-Newtonian serta mekanisme penyimpanan panas laten yang terjadi selama transisi fasa partikel NEPCM. Persamaan tak berdimensi yang diperoleh diselesaikan secara numerik untuk mengevaluasi pengaruh indeks hukum daya, konsentrasi kapsul, dan suhu fusi terhadap distribusi kecepatan, suhu, rasio kapasitas panas, serta bilangan Nusselt. Hasil penelitian menunjukkan bahwa peningkatan konsentrasi kapsul mempercepat aliran, meningkatkan suhu sistem, serta memperluas wilayah transisi fase, dengan pengaruh yang paling dominan teramati pada fluida dilatan. Selain itu, laju perpindahan panas meningkat signifikan seiring penambahan konsentrasi kapsul, dengan peningkatan tertinggi pada nanofluida dilatan dibandingkan Newtonian maupun pseudo-plastik.

Abstract

This study evaluates the co-firing of palm oil industry waste biomass, specifically Palm Kernel Shell (PKS) and Empty Fruit Bunch (EFB) pellets, in coal-fired power plants (PLTU) in Riau, Indonesia, to support a sustainable energy transition. Empirical tests were conducted at PLTU Tenayan and Tembilahan, using biomass substitution rates of 5% and 50%, respectively. Key performance indicators, including Specific Fuel Consumption (SFC), Net Plant Heat Rate (NPHR), production cost, and exhaust emissions (SO₂ and NOₓ), were analyzed. Results show that 5% PKS co-firing at PLTU Tenayan reduced SFC from 0.871 to 0.856 kg/kWh and NPHR from 4,187 to 4,116 kCal/kWh, while 50% PKS co-firing at PLTU Tembilahan decreased SFC from 1.171 to 0.785 kg/kWh and NPHR from 5,312 to 3,625 kCal/kWh. Economically, PKS co-firing resulted in cost savings of up to Rp223.58/kWh. Emission measurements revealed SO₂ reductions up to 27.8% at PLTU Tenayan and 34% at PLTU Tembilahan (EFB scenario), with NOₓ emissions remaining stable or decreasing by up to 13%. Conversely, EFB pellet co-firing increased fuel consumption and production costs due to higher fuel prices and operational challenges. The study confirms that PKS co-firing is a viable and effective approach to enhance power plant efficiency, reduce emissions, and lower costs in palm oil-producing regions. Limitations include short test durations and limited plant sites; therefore, long-term monitoring is recommended to assess boiler integrity, operational stability, and emission performance for sustainable large-scale implementation. This research provides critical technical, economic, and environmental insights for advancing biomass co-firing in commercial coal power plants.

Abstract

Persaingan pasar peralatan industri menuntut perusahaan tidak hanya membangun citra merek, tetapi juga menyediakan layanan purnajual yang mampu mendorong kepuasan dan rekomendasi pelanggan. Penelitian ini bertujuan menganalisis pengaruh brand image dan after sales service terhadap word of mouth (WOM), baik secara langsung maupun melalui kepuasan pelanggan sebagai variabel mediasi pada pengguna Power Tools Makita Industrial di kawasan KIIC Karawang. Penelitian menggunakan pendekatan kuantitatif dengan desain eksplanatori. Sampel terdiri atas 100 pengguna aktif Power Tools Makita Industrial pada PT Toyota Motor Manufacturing Indonesia, PT Astra Daihatsu Motor Engine, dan PT Isuzu Astra Motor Indonesia yang dipilih menggunakan non-probability sampling dengan metode accidental sampling. Data dikumpulkan melalui kuesioner skala Likert lima tingkat dan dianalisis menggunakan PLS-SEM dengan SmartPLS 4.0. Hasil penelitian menunjukkan bahwa after sales service berpengaruh positif dan signifikan terhadap WOM (β=0,215; p=0,044), sedangkan kepuasan pelanggan berpengaruh positif dan signifikan terhadap WOM (β=0,229; p=0,029). Sebaliknya, brand image tidak berpengaruh signifikan terhadap WOM maupun kepuasan pelanggan, dan after sales service tidak berpengaruh signifikan terhadap kepuasan pelanggan. Pengujian specific indirect effect menunjukkan bahwa kepuasan pelanggan tidak memediasi pengaruh brand image maupun after sales service terhadap WOM. Temuan ini menunjukkan bahwa dalam konteks sampel pengguna peralatan industrial, WOM terutama berkaitan dengan pengalaman layanan purnajual dan kepuasan pelanggan secara langsung, bukan melalui mekanisme mediasi yang dihipotesiskan. Secara praktis, penyedia peralatan industri perlu memperkuat konsistensi layanan purnajual dan pengalaman pelanggan untuk mendorong rekomendasi positif. The Influence of Brand Image and After Sales Service on Word of Mouth with Customer Satisfaction as Mediating Variable Abstract Competition in the industrial equipment market requires companies not only to establish a strong brand image but also to provide after-sales services that foster customer satisfaction and positive recommendations. This study aims to examine the effects of brand image and after-sales service on word of mouth (WOM), both directly and indirectly through customer satisfaction as a mediating variable among Makita Industrial Power Tools users in the KIIC industrial area, Karawang. This study employed a quantitative explanatory design involving 100 active users of Makita Industrial Power Tools from PT Toyota Motor Manufacturing Indonesia, PT Astra Daihatsu Motor Engine, and PT Isuzu Astra Motor Indonesia, selected through non-probability accidental sampling. Data were collected using a five-point Likert-scale questionnaire and analyzed using PLS-SEM with SmartPLS 4.0. The results demonstrate that after-sales service has a positive and significant effect on WOM (β=0.215; p=0.044), while customer satisfaction also positively and significantly affects WOM (β=0.229; p=0.029). Conversely, brand image has no significant effect on either WOM or customer satisfaction, while after-sales service does not significantly affect customer satisfaction. The specific indirect effect analysis further reveals that customer satisfaction does not mediate the effects of either brand image or after-sales service on WOM. These findings indicate that, within the sampled industrial users, WOM is primarily associated with direct after-sales service experiences and customer satisfaction rather than the hypothesized mediation mechanisms. Practically, industrial equipment providers should strengthen the consistency of after-sales services and customer experiences to encourage positive recommendations.
