Abstract

This study discusses the Determinan yang mempengaruhi kepuasan hunian dan "Word of Mouth" di Villa Ana Residence Samarinda. More specifically, the objectives of this study were 1) to determine and analyze the effect of the product on the Company's customer satisfaction at Villa Ana Residence Samarinda, 2) To identify and analyze the effect of the price to the consumer on Villa Ana Housing Residence Samarinda, 3) To identify and analyze the influence of service developers to consumer satisfaction at Villa Ana Housing Residence Samarinda, 4) identify and analyze the effect of customer satisfaction on WOM (Word of Mouth) in Company Villa Ana Residence Samarinda. Results showed that: 1) The product positive and significant effect on customer satisfaction in the Villa Ana Residence Samarinda, 2) Prices are not positive and significant effect on customer satisfaction in the Villa Ana Residence Samarinda, 3) Developer Services and significan positive effect on customer satisfaction in Villa Ana Residence Samarinda, 4) positive customer satisfaction and significantly towards WOM (Word of Mouth) in Villa Ana Residence Samarinda. The Results of this study provide practical implications that the Villa Ana Residence particularly emphasized that the indicator products in the diversity of products, product quality, design, size and Warranty. Services confidence indicator developer or Reliability, Responsiveness or Responsibility, Confidence or Assurance, Empaty and Tangible. The practical implication of this research is that it can be used as a reference by the Party Villa Ana Residence Management to improve determinants or factors affecting residential satisfaction and "Word of Mouth" at Villa Ana Residence Samarinda based on 24 indicators.

Abstract

Almonds (Prunus dulcis) are widely valued for their nutritional composition and sensory properties, and roasting is commonly applied to enhance their flavor and extend their shelf life. However, thermal processing can degrade bioactive compounds and promote acrylamide formation. This study examined the effects of spouted-bed fluidization roasting at temperatures ranging from 150 to 180 °C for 5 to 7 min on acrylamide levels, antioxidant activity, physicochemical characteristics, and sensory profiles of almonds. The analytical methods included texture analysis, ultra-performance liquid chromatography (UPLC), colorimetry, Fourier-transform infrared spectroscopy (FTIR), and descriptive sensory evaluation. Acrylamide concentrations ranged from undetectable levels (<40 ppb) at 150 °C for 5 min to 1,672 ppb at 180 °C for 7 min. Total phenolic content increased at higher roasting temperatures (170–180 °C), reaching up to 0.90mg GAE/g, while antioxidant activity decreased from 0.51MBHA/g in raw almonds to 0.15–0.37MBHA/g in roasted samples. Roasting also reduced the moisture content (from 5.38% to 1.09%) and fracturability (from 102.39N to 71.81N), increased the browning intensity (BI: 42.13 to 30.77), and altered the FTIR spectra, indicating the formation of esters and carboxylic acids via Maillard reactions. Sensory evaluation showed that higher temperatures enhanced crispiness and aroma, but also increased bitterness and burnt characteristics. Overall, spouted-bed roasting at 160–170°C for 5–7 min minimized acrylamide formation while maintaining favorable sensory quality and preserving phenolic compounds. These results provide a basis for optimizing almond roasting parameters to improve safety and nutritional retention.

Abstract

Pemanfaatan mesin sangrai kopi tipe spouted bed di Indonesia masih sangat sedikit, sehingga data kopi sangrai juga sangat terbatas. Tujuan dari penelitian ini untuk mengetahui pengaruh level sangrai menggunakan spouted bed roaster terhadap sifat fisikokimia kopi robusta dan arabika Temanggung pada level sangrai light, medium dan dark. Sifat fisikokimia yang diamati meliputi kadar air, warna, antioksidan dan kandungan kafein. Penelitian ini menghasilkan bahwa kadar air kopi menurun seiring dengan meningkatnya tingkat sangrai, dimana kadar air terendah terdapat pada robusta 1,18% dan arabika 1,27% pada level sangrai dark. Uji Warna (Chromameter) menunjukkan nilai L* yaitu 30,07 (light), 26.20 (medium), dan 21,92 (dark) untuk kopi robusta dan 28,80 (light), 25,10 (medium), dan 22,85 (dark) untuk kopi arabika. Nilai dari Browning Index (BI) mempunyai pola mirip dengan nilai L*. Nilai antioksidan tertinggi yaitu level sangrai light baik untuk jenis kopi robusta (12,65 MBHA/g) dan arabika (5,99 MBHA/g) Temanggung. Nilai antioksidan berbanding terbalik dengan tingkat sangrai. Tingkat sangrai kopi berbanding lurus dengan kadar kafein dimana nilai tertinggi kadar kafein terdapat pada level sangrai dark baik untuk kopi jenis robusta (1.61 ± 0.02 g/100g d.b.) dan arabika (0,84 ± 0,03 g/100g d.b.) Temanggung. Kata kunci: arabika, kopi Temanggung, robusta, spouted bed, sangrai kopi
