Susu memiliki karakteristik mudah rusak dan tidak tahan lama sehingga perlakuan pascapanen penting untuk diperhatikan sehingga susu sapi mulai diolah agar tahan lama ketika disimpan seperti susu pasteurisasi dan susu UHT (Ultra High Temperature). Kesadaran masyarakat dalam memenuhi kebutuhan gizi juga telah mengalami peningkatan dilihat dari masyarakat mulai mengkonsumsi susu sapi. Hal ini mempengaruhi semakin banyak industri pengolahan susu yang memproduksi susu cair kemasan sehingga menyebabkan adanya persaingan antar industri. Oleh karena itu, penelitian ini bertujuan untuk menganalisis pengaruh green marketing (green product, green price, dan green promotion) dan brand image terhadap keputusan pembelian produk susu cair kemasan. Pengumpulan data pada penelitian ini dilakukan dengan kuesioner menggunakan teknik purposive sampling. Total sampel yang digunakan yaitu 126 orang. Metode yang digunakan untuk melakukan analisis data yaitu metode regresi linear berganda dengan green marketing (green product, green price, dan green promotion) dan brand image sebagai variabel bebas sedangkan keputusan pembelian sebagai variabel terikat. Hasil penelitian menunjukkan bahwa secara simultan green product, green price, green promotion, dan brand image secara bersama-sama berpengaruh positif signifikan terhadap keputusan pembelian produk susu cair kemasan. Sementara pengujian secara parsial dari empat variabel yang digunakan, hanya terdapat satu variabel yang berpengaruh positif terhadap keputusan pembelian yaitu green promotion.

Beluntas (Pluchea indica Less) leaves possess significant potential as functional food ingredients, yet their storage stability in vegetable leather form requires rigorous quantification. This study analytically determines the shelf life of beluntas and seaweed vegetable leather using a kinetic modeling approach based on the Accelerated Shelf Life Testing (ASLT) Arrhenius model. A two-factor experimental design evaluated three packaging systems (Aluminum Foil, Aluminum Foil-Polyethylene, and Polypropylene) across three isothermal conditions (30, 35 and 40 °C). Quality degradation was monitored via protein content, Vitamin C, and browning index at 7 day intervals for 28 days. Statistical regression was performed using the Data Analysis Toolpak to ensure model reliability. Kinetic analysis revealed that vitamin C degradation, identified as the critical quality indicator, followed first-order kinetics. The model was validated by high coefficients of determination (R2 up to 0.9721) and low Root Mean Square Error (RMSE) values (0.0352–0.1738). The calculated activation energy (Ea) ranged from 14.72 to 19.44 kJ/mol, explaining the product's temperature sensitivity. At 30 °C, the predicted shelf life was 16.87 days for aluminum foil, 12.96 days for combination packaging, and 9.96 days for polypropylene.

Jamur liar (Volvariella volvacea) berpotensi dikembangkan menjadi produk pangan nabati bernilai tambah karena memiliki kandungan gizi dan dapat diperoleh dari tandan kosong kelapa sawit. Pemanfaatan jamur liar sebagai bahan baku abon dengan penambahan santan kelapa dapat menjadi salah satu alternatif diversifikasi produk pangan. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi santan kelapa terhadap karakteristik sensoris dan kimia abon jamur liar. Penelitian menggunakan Rancangan Acak Lengkap dengan tiga taraf konsentrasi santan kelapa, yaitu 10%, 20%, dan 30%, dengan lima kali ulangan. Parameter yang diamati meliputi karakteristik sensoris berupa warna, aroma, tekstur, rasa, dan penerimaan keseluruhan, serta kadar air, kadar abu, kadar protein, kadar lemak, dan kadar serat kasar. Data dianalisis untuk mengetahui pengaruh perlakuan terhadap parameter yang diamati. Hasil penelitian menunjukkan bahwa konsentrasi santan kelapa berpengaruh nyata terhadap karakteristik sensoris, kadar air, kadar abu, kadar protein, dan kadar lemak, tetapi tidak berpengaruh nyata terhadap kadar serat kasar. Penambahan santan kelapa sebanyak 20% menghasilkan tingkat kesukaan tertinggi pada seluruh atribut sensoris, dengan kadar air 6,81%, kadar abu 6,20%, kadar protein 16,61%, kadar lemak 30,50%, dan kadar serat kasar 5,47%. Penambahan santan kelapa sebanyak 20% merupakan formulasi terbaik untuk menghasilkan abon jamur liar dengan karakteristik sensoris yang paling disukai dan karakteristik kimia sesuai hasil penelitian.

Kabupaten Sanggau memiliki area perkebunan kelapa sawit seluas 449.167,69 ha dengan 47 pabrik kelapa sawit yang menghasilkan limbah tandan kosong kelapa sawit (TKKS) dalam volume besar. Selama dekomposisi TKKS, tumbuh jamur liar edible yang dikenal sebagai jamur sawit (Volvariella volvacea), berpotensi sebagai sumber pangan alternatif kaya protein, namun pemanfaatannya oleh masyarakat masih konvensional dan bernilai ekonomi rendah akibat keterbatasan pengetahuan pengolahan. Tim Pengabdian kepada Masyarakat (PKM) PSDKU POLNEP Sanggau menginisiasi program transfer teknologi pengolahan jamur sawit menjadi produk abon bergizi dan bernilai ekonomi tinggi, dengan sasaran 15 orang mitra Tim Penggerak PKK di Kelurahan Beringin. Kegiatan dilaksanakan melalui penyuluhan, demonstrasi plot, praktik mandiri pembuatan abon, serta serah terima mesin peniris minyak (spinner). Hasil evaluasi menunjukkan peningkatan pemahaman mitra dari 6,67% (pre-test) menjadi 100% (post-test), disertai kemampuan mitra mempraktikkan mandiri seluruh tahapan produksi abon selama sesi demplot, meskipun pembentukan kelompok usaha dan produksi berskala komersial masih memerlukan pemantauan lanjutan melalui Perjanjian Kerja Sama (PKS) yang telah disepakati. Tingkat kepuasan peserta terhadap pelaksanaan program berada pada rentang 60–93% (skala Setuju hingga Sangat Setuju) di seluruh indikator layanan. Luaran utama kegiatan meliputi produk abon jamur sawit, publikasi media massa dan video dokumentasi, serta PKS sebagai landasan monitoring keberlanjutan usaha mitra pascakegiatan. Sanggau Regency has an oil palm plantation area of 449,167.69 ha with 47 operating palm oil mills generating large volumes of empty fruit bunch (EFB) waste. During EFB decomposition, edible wild mushrooms grow abundantly and are locally known as oil palm mushrooms (Volvariella volvacea), which have potential as a protein-rich alternative food source, although their utilization by the community remains conventional and of low economic value due to limited knowledge of processing methods. The Community Service (PKM) team of PSDKU POLNEP Sanggau initiated a technology transfer program on processing oil palm mushrooms into nutritious, high-value shredded product (abon), targeting 15 partners from the Family Welfare Empowerment Movement (PKK) in Beringin Village. The activity was carried out through counseling, a demonstration plot, hands-on practice in producing abon, and the handover of an oil-draining spinner machine. Evaluation results showed an increase in partners' understanding from 6.67% (pre-test) to 100% (post-test), with partners demonstrating the ability to independently practice all stages of abon production during the demplot session, although the formation of a formal business group and commercial-scale production remain subject to further monitoring under the signed Cooperation Agreement (PKS). Participant satisfaction with the program ranged from 60–93% (Agree to Strongly Agree) across all service indicators. Key outputs of the activity include the oil palm mushroom abon product, mass media publication and documentation video, and the PKS as the basis for monitoring the sustainability of partners' enterprise beyond the activity period.
