Background; petai (Parkia speciosa) is a plant commonly grown and consumed in Southeast Asia, especially Indonesia, Malaysia, and Thailand. The main part of petai that is usually consumed is its seed, while the skin is removed, not used, and becomes waste. Objectives; to analyze 1) the potential for processing and utilizing petai skin waste (PSW) to be a source of antioxidants; 2) the antioxidant extraction process on PSW; 3) antioxidant activity, total phenol, and total flavonoids obtained from PSW; and 4) strategic steps for sustainability of PSW utilization. Materials and Method; this study used secondary data which obtained from literature review. Data was analyzed descriptively by describing and comparing the results of external research related to the utilization of PSW as an antioxidant source. Results; based on ethanol extraction results, PSW has higher antioxidant activity (250 mg/g) than the seeds and the leaf. Petai skin extraction process was carried out by solvent extraction method with various types of solvent. Antioxidant activity was determined by FRAP, ABTS, and DPPH method, while total phenol analysis was used Folin-Ciocalteu method and total flavonoid analysis using the colorimetric method. Based on the economic aspect, the utilization of PSW had a positive impact on the welfare of society, from the social aspect, the utilization of food waste could increase awareness, acceptance, and comfort for the community, from environmental and health aspects, waste utilization could reduce contamination and disease source. Conclusion; PSW had the potential as a source of antioxidants.

This study aims to determine the effect of visual packaging design consisting of color, shape, and size and packaging labeling consisting of composition, nutritional value information, and claims on purchase intention of pre-packaged food products. The method used is a descriptive method with a quantitative approach. The research period was conducted in April 2020 with 200 respondents using linear regression analysis. The results of this study indicate that visual packaging design and packaging labeling significantly influence the purchase intention of packaged food products at a significance level of 0.05. The regression equation that is formed from the results of this study is Y = 3.487 + 1.323X1 + 0.677X2. Companies can focus more on developing packaging designs and delivering product information such as information on composition, nutrition, and product claims accompanied by scientific evidence. Penelitian ini bertujuan untuk mengetahui pengaruh visual packaging design yang terdiri atas warna, bentuk, dan ukuran serta packaging labeling yang terdiri atas komposisi, informasi nilai gizi, dan klaim terhadap purchase intention produk makanan dan minuman dalam kemasan. Metode yang digunakan adalah metode deskriptif dengan pendekatan kuantitatif. Periode penelitian dilakukan pada bulan April 2020 dengan responden sebanyak 200 orang. Penelitian ini menggunakan analisis regresi linear. Hasil dari penelitian ini menunjukkan bahwa visual packaging design dan packaging labeling secara signifikan berpengaruh terhadap purchase intention produk pangan dalam kemasan pada level signifikansi 0.05. Persamaan regresi yang terbentuk dari hasil penelitian ini adalah Y = 3,487 + 1,323X1 + 0,677X2. Perusahaan dapat lebih fokus dalam pengembangan desain kemasan dan penyampaian informasi produk seperti informasi komposisi, nutrisi, dan klaim yang bertanggung jawab disertai dengan bukti-bukti ilmiah.
