Abstract

Most of coastal regions in Indonesia have experienced water scarcity where water resources are becoming more and more threatened due to the rapid growth of population, aquaculture industries and agricultures. Brackish water reverse osmosis (BWRO) desalination may be used to overcome the supply potable water problem in the coastal regions. Brackish water having total dissolved solids (TDS) content in the range of 1,000–10,000 ppm can be desalinated at a reasonable cost. This work was aimed to find valuable technical data for plant design and operation. Cost analysis also was conducted to obtain specific water cost. The results show that stable system performance was achieved. Based on a case study of small scale BWRO with capacity of 50 m3/day, specific water cost was around of IDR 6,100/ m3.

Abstract

Riset ini bertujuan untuk menentukan kadar air dan laju pengeringan terhadap pengeringan labu kuning dengan menggunakan menggunakan oven Memmert type UN 110 (Memmert GmbH + Co. KG, Deutschland). Target yang ingin dicapai berupa kondisi operasi yang digunakan dalam melakukan proses pengeringan. Kajian dilakukan pada berbagai variabel, meliputi suhu (70, 90, 120 0C)  dan tebal irisan (2, 3, 5 mm). Selama percobaan didapat hasil sebagai berikut: kadar air labu kuning terendah pada suhu 90ºC yaitu 53.96% dengan ketebalan 3 mm serta hasil laju pengeringan maksimumnya pada suhu 120ºC yaitu 0.080 gram/menit dengan ketebalan 5 mm. Waktu pengeringan dengan hasil tercepat yaitu 180 menit pada suhu 70ºC dengan ketebalan 3mm dengan laju pengeringan total 0,135 gr/mnt.Kata kunci: kadar air, labu kuning, laju pengeringan, oven elektrik

Abstract

Penelitian  ini bertujuan untuk memekatkan filtrat buah nanas menggunakan proses evaporasi. Dasar dari proses ini adalah pengurangan kadar air di dalam filtrat buah nanas  pada tekanan pengukur 65 cmHg dengan variabel bebas meliputi suhu (40–60 °C ), konsentrasi (20–40 g/l) dan waktu (30–90 menit), serta menguji parameter terukur meliputi kadar TSS, pH, dan konduktivitas pada hasil akhir evaporasi sebagai variabel bergantung.  Hasil studi parameter dioptimasi dengan penentuan variabel berpengaruh menggunakan Central Composite Rotational Design (CCRD). Penelitian memberikan hasil nilai kadar TSS optimum mencapai nilai kadar TSS lebih dari 8000 mg/L  dengan konsentrasi 42–44 g/L pada suhu 48–50 °C selama 50–60 menit. Kata kunci: evaporasi, nanas, kadar TSS

Abstract

This work proposed a study of a direct enzymatic of vanillin formation by using rumen liquid which has enzymatic capability for tissue disruption of vanilla green pods to avoid the curing process. Application of enzymes during the formation of vanilla aromas and its extraction present nice opportunity to improve productivity, as the enzymatic reaction possibly substitute the microbial process in the traditional fermentation. Green vanilla pods were applied for the direct enzymatic extraction of vanillin, while liquid rument provide cell wall degrading enzyme in order to support the hydrolysis process (destruction) of cell wall. Glucovanillin were contacted with the β-glucosidase in the green pods due to the desruction of the cell wall, followed by the formation of glucovanillin into vanillin. Vanillin content of vanilla green pods was found higher in which by treating the vanilla green pods at 30 °C.

Abstract

An imbalance in the body's number of antioxidants and free radicals can cause oxidative stress and trigger various degenerative diseases (WHO, 2016). One way to prevent free radicals from entering the body is to bathe with soap. Black rice extract can be an antioxidant in soap because it contains anthocyanin pigments and has high bioactive compounds (Chakuton et al., 2012). Selection of Virgin Coconut Oil (VCO) as a raw material for soap because it has a high lauric acid content and is helpful for moisturizing and smoothing the skin (Afrozi et al., 2021). This study aimed to analyze the quality of liquid soap from the hydrolyzed Virgin Coconut Oil (VCO) and the effect of using bases KOH, NH4OH, and black rice extract accompanied by varying base concentrations, time, and temperature treatments. The independent variables for process optimization were the concentration of KOH: NH4OH (30:70, 50:50, 70:30)%, stirring time (65, 85, 105) minutes, and operating temperature (60, 75, 90) °C. Based on the results obtained, the optimum level of FFA (resulting in a small FFA%) was obtained with the minimized variable conditions, namely using a concentration of 16,4% KOH, and an operating temperature of 49,7 °C, a stirring time of 51.4 minutes, and composite desirability of 0,895897.
