Abstract

Indonesia, as one of the biggest countries which supplies citronella oil, has a high potential to produce natural rhodinol. Recent studies on rhodinol purification using fractional and mollecular distillation showed the difficulty of obtaining high purity and yield. The objective of this study was to determine the method of spinning band distillation to purify rhodinol regarding reflux ratio and vaporization temperature. Citronella oil was divided into three fractions according to its boiling points. The volume of each fraction was estimated by its ratio (according to GC analysis) to the feed volume: F1 (components before rhodinol) 21.73%, F2 (rhodinol) 61.7%, and residue 15.82%. Initial research established the best conditioning before the purification process was 3 mmHg of pressure, equilibration started at 160oC in 30 minutes, and 18–17% of heat rate, as these created the stability of the vapor temperature. The levels of reflux ratio were 3:1 and 5:1, while the evaporation temperatures of rhodinol were 230oC and 235 oC. Reflux ratio of 5:1 at 230oC obtained the highest purity (81.30%) and the highest yield (72.94%). Equilibration and reflux ratio allowed rectification inside the column because the spinning band homogenized the vapour molecules by its downwards flow and wiped the reflux on the inner surface, which in turn caused the molecules with a lower boiling point to evaporate gradually. Meanwhile the other yields were 79.81% (3:1 at 230 oC), 80.53% (3:1 at 235 oC), and 80.21% (5:1 at 23oC) with yields of 71.82%, 70.31%, and 68.23%.

Abstract

Dalam beberapa tahun terakhir, pembuatan nanopartikel besi telah menjadi perhatian karena efisiensinya pada penghilangan beberapa jenis zat pencemar. Zat-zat pencemar yang dapat diolah dengan nanopartikel besi antara lain senyawa azo, pelarut terklorinasi, pestisida terklorinasi, anion anorganik dan logam transisi, polutan organik dan anorganik, logam berat, nitrat, bromida, arsen, kromium, timbal, antibiotik,  dan pewarna. Pada umumnya, pembuatan nanopartikel besi dilakukan dengan mereduksi besi bermuatan tiga/dua dengan natrium tetra borana, NaBH4. Pembuatan nnanopartikel besi menggunakan NaBH4 menghasilkan produk samping berupa asam borat yang beracun dan gas hidrogen yang mudah meledak atau terbakar. Penelitian ini bertujuan membuat nanopartikel besi dengan memanfaatkan limbah scrap besi menjadi copperas kemudian mereaksikan dengan ekstrak kulit rambutan. Metode yang dilakukan adalah mereaksikan scrap besi dengan asam sulfat sampai terbentuk copperas yang berwarna biru kehijauan. Copperas yang dihasilkan dibuat menjadi larutan kemudian direksikan dengan ekstrak kulit rambutan. Larutan hitam yang dihasilkan dikarakterisasi dengan Spektrofotometri UV-Vis dan TEM. Larutan berwarna hitam dikeringkan dengan cara spray drying kemudian serbuk nanopartikel besi dikarakterisasi dengan XRD, FTIR, dan SEM-EDX. Hasil penelitian menunjukkan bahwa scrap besi dapat dibuat menjadi copperas dengan kadar Fe 22,09%. Ekstrak kulit rambutan mengandung kadar fenol total 877,39 ± 16,6 ppm/100 g kulit rambutan atau setara dengan 441,42 mg GAE/100 g kulit rambutan. Nanopartikel besi berhasil dibuat dari copperas dari scrap besi dan ekstrak kulit rambutan yang mempunyai karakter Surface Plasmon Resonance (SPR) pada serapan 214 nm, ukuran partikel 5-20 nm  dalam bentuk larutan dan 20-70 nm dalam bentuk serbuk. Hasil ini bisa menjadi alternatif produksi nanopartikel besi  suatu material bermanfaat untuk mencegah terjadinya pencemaran lingkungan.       ABSTRACTIn recent years, the manufacture of iron nanoparticles has become a concern because of its efficiency in removing several types of contaminants. Pollutants that can be treated with iron nanoparticles include azo compounds, chlorinated solvents, chlorinated pesticides, inorganic anions and transition metals, organic and inorganic pollutants, heavy metals, nitrates, bromides, arsenic, chromium, lead, antibiotics, and dyes. In general, the manufacture of iron nanoparticles is carried out by reducing three/two charged iron with sodium tetra borane, NaBH4. The manufacture of iron nanoparticles using NaBH4 produces toxic by-products in the form of boric acid and hydrogen gas which is flammable or explosive. This study aims to make iron nanoparticles by utilizing scrap iron waste into copperas then reacting it with rambutan peel extract. The method used is to react iron scrap with sulfuric acid to form copperas which is blue-green in color. The resulting copperas were made into a solution and then treated with rambutan peel extract. The resulting black solution was characterized by UV-Vis Spectrophotometry and TEM. The black solution was dried by spray drying and then the powdered iron nanoparticles were characterized by XRD, FTIR, and SEM-EDX. The results showed that iron scrap can be synthesized into ferrous sulfate with 22.09% Fe content. Rambutan peel extract contains a total phenol content of 877.39 ± 16.6 ppm/100 g rambutan peel or equivalent to 441.42 mg GAE/100 g rambutan peel. Iron nanoparticles were successfully made from copperas from iron scrap and rambutan peel extract with the characteristics of having Surface Plasmon Resonance (SPR) at an absorption of 214 nm, particle size of 5-20 nm in solution form and 20-70 nm in powder form. This result can be an alternative for the production of iron nanoparticles, a useful material to prevent environmental pollution.

Abstract

Egg is breed product that contains nutrients which easy to digest and exploited by the body. Egg is easily damaged and so it need to be preserved. One way to preserve is salted using sodium chloride (NaCl). The salt functions are to prevent the growth of bacteria, improve the taste and practical value. The longer it is ripened in the salting media, it will be more salty, because more salts are absorbed in the egg. The ewperiment was aimed tho know the NaCl content absorbed in the egg from salting media with various ripening time.Determination of NaCl content in the egg used Mohr Argentometric method i.e. the use of AgNO3 standard solution and K2CrO4 indicator. The determination of NaCl was done in duck eggs obtained from salting in week-0, 1, 2 and 3. Each treatment used 3 replications. The statistic used was one way analysis of varian (ANOVA) continued with SNK test.NaCl contents in the egg before salted were 0.34%  in the egg white and 0.33% in the egg yolk. The NaCl content that was absorbed in the egg white from salting media after salted in week-1,2 and 3 were 2.77%, 3.71% and 5.09% respectively. While in the egg yolk the contents were 0.43%, 0.71% and 0.97% respectively. After statistically tested by one way anova and continued by SNK test it could be consluded that there was significant difference of NaCl content absorbed in the egg white and yolk from salting media inter-time of ripening.

Abstract

People in rural areas usually have minimal knowledge or information about healthy eating patterns related to nutritionally balanced foods, due to their habits that take it for granted. The increasing number of cases of disease suffered by the community due to unhealthy and inappropriate eating patterns in the selection of food intake for families, especially to deal with this COVID-19 pandemic, it is necessary to provide health education to the community related to healthy eating patterns. As the target audience for the implementation of this service, the community of Triyagan Village, District, Mojolaban, Sukoharjo Regency, includes the stages of preparation, giving pre-test and post-test, presenting material and conducting evaluations. The results of the pre-test and post-test evaluations on knowledge of healthy eating patterns showed a positive direction with an increase in value/score, from an average of 61 to 79 (scale score of 100) after receiving counseling. This evaluation shows that there has been a change in mindset about a healthy lifestyle as an effort to prevent the Covid-19 virus during the pandemic.

Abstract

Salting is done to extend the shelf life of duck eggs. A variety of media can be used for salting eggs, including a mixture of salt, sand, red brick, sawdust, and brewed tea. Salted eggs are popular among the general public, but they contain a lot of fat, which, if consumed in excess, can cause blood vessel blockage (atherosclerosis). Green tea is a plant that has many benefits, one of which is that it can help people lose weight. Duck eggs were ripened for 12 days in a variety of salting media with different ingredients for this study. Red bricks, sand, sawdust, salt, and brewed green tea are among the materials used. This study aimed to determine the fat content of salted egg yolks using the Soxhlet extraction method, as well as the color, aroma (smell), and taste of salted eggs. The data in this study were analyzed using One-Way ANOVA and the results revealed that variations in salting media had a significant effect on fat content in salted egg yolks. The results showed the changes in fat content in salted egg yolks without treatment with a fat content of 36.28 percent, and with treatment with media A (sand, red bricks, and sawdust); media B (sand, red bricks, and sawdust); media 1 (media A added with green tea); and media 2 (media B added with green tea), with the fat contents of 35.22%; 32.86%, and 30.49%. Mixed media of green tea affects the fat content of salted egg yolks, from 36.50% to 32.86% and 30.49%.

Abstract

The role of the community in waste management at this time is generally limited to waste disposal. We are not yet at the stage of waste management where waste can be reused by the community. Waste management must be handled comprehensively with the 3R principle, namely reduce, namely reducing waste piles; reuse by reusing waste that is not used; and recycle, namely recycling into products of economic value. Good waste management is expected to reduce the volume of waste that is disposed of at the final disposal site (TPA). The need for community education on proper waste management and disposal in order to reduce the impact of environmental pollution.The service was carried out in Triyagan Village, Mojolaban District, Sukoharjo Regency, at the beginning of the activity by giving a pre-test, presenting the material, and at the end of the activity, namely an evaluation with a post-test.
