Abstract

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.

Abstract

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.

Abstract

Forecasting analysis was used to predict the availability of Robusta coffee in Lampung as a basis for developing innovative coffee-based products, such as spiced coffee. Furthermore, financial analysis was conducted to assess the feasibility of processing spiced coffee as a regional flagship product. This research was conducted through a literature study from various sources, and data analysis was performed using POM-QM for Windows Version 3 software. The results of the study show that Robusta coffee production in Lampung tends to be stable from 2022 to 2026. In 2026, Robusta coffee production in Lampung will reach 116,272 tons. Financial analysis shows feasibility with an NPV of IDR 167,473,835.26, IRR of 222%, Net B/C of 2.76, Gross B/C of 1.26, and a PBP of 1 year. The investment can be recouped in 2 years, making the spice coffee home industry a viable venture to develop.
