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

As a basic human need, the development of textiles still needs to be studied. At first, the textile dyeing process used natural dyes. However, along with the development of technology with the discovery of synthetic dyes for textiles, the use of natural dyes began to be abandoned. Natural color fabrics have many advantages, while promoting disadvantages, such as the appearance of microorganisms on the fabric. To improve the function of the fabric, the addition of antibacterial agent to the fabric is important. This study aims to investigate the optimum condition for producing natural color fabric from Terminalia Belerica’s peel with the application of TiO2 as an antibacterial agent, using the pad dry cure method. The results of the TiO2 coating process on natural dye fabrics are based on its antimicrobial activity. SEM EDX, color strength, and fabric stiffness were also characterized by its physical properties. The analysis results show that the most optimum condition for the stability of color aging was in the 2nd experiment at a concentration of TiO2 at 1%, without curing and sizing of 75%. For stiffness stability analysis, the optimum result was obtained in the third experiment, namely the concentration of TiO2 at 0.5%, with curing and without sizing of 98%. The most influential effects on the antibacterial test include aging, brightness, and stiffness, namely variable sizing with a negative effect. The results of testing antibacterial activity on natural color fabrics of jolawe fruit peel extract applied with TiO2 show that the assessment process caused the fabric to be easily contaminated by bacteria, where the inhibition zone value was 0 mm. The SEM-EDX test did not show any damage to the fabric, and there were grains or lumps on the fabric fibers due to TiO2 coating.
