One of the factors causing the decline in potato production is because local farmers have not been optimal in producing G0 potato tuber seeds, still using conventional methods, so to meet the need for G0 potato tuber seeds, farmers buy them from outside the region. Efforts that can be made to increase seed production are by utilizing technology in the agricultural sector such as aeroponic systems. Aeroponics is a farming activity carried out by hanging plant roots in a container where the plant roots then receive water and nutrients through spraying in the form of mist droplets. The aim of the research is to design and create an aeroponics system that can work automatically to maintain the concentration of the solution and the availability of water in the box container so that it can meet the nutritional needs for potato plant growth. This research starts from functional design, structural design, control system design, calibration, technical testing and analysis. The performance of the total dissolved solid (TDS) sensor during the 10 week study obtained an error value of 7.398% and an accuracy level of 92.602% with an average range of TDS sensor reading values of 1,142,000 ppm – 1,358,333 ppm. Meanwhile, the performance of the HC-SR04 sensor obtained an error value of 1.300% and an accuracy level of 98.700% with a range of reading values for the HC-SR04 sensor, namely 12 cm – 26 cm. The results of observations of plant growth in the form of plant height showed that the average plant height at week 13 was 42.175 cm/stem, the average number of leaf stalks was 14.8 stalks. The number of tubers produced by the aeroponic system is 14,850 tubers/stem, which is more than the conventional method, namely 5-7 tubers/stem. The aeroponic system can work well because the aeroponic system is able to maintain the concentration of the solution according to plant growth needs (1,050 ppm - 1,400 ppm) and the system can maintain the availability of water in the box container.","PeriodicalId":17692,"journal":{"name":"Jurnal Teknologi Pertanian","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138974019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adding cinnamon powder to cane sugar provides additional benefits for body health. One of the quality criteria for molded cane sugar is its hardness. The hardness value of printed cane sugar changes during storage; the sugar becomes softer and less complicated. Reaction kinetics can be used to observe changes in the hardness of printed cane sugar. The Arrhenius method was used in this research to determine how adding cinnamon powder affects the quality of molded cane sugar. This research used molded cane sugar with two concentrations of cinnamon powder, namely 0% and 0.255%. The sugar was then stored at three different temperatures, seven °C, 27 °C, and 45 °C, over 30 days, with daily observations. Kinetic analysis of molded cane sugar shows that when cinnamon powder is added, the quality decreases more quickly compared to control molded cane sugar, which has a k value of 0.3378 N/cm2/day at a temperature of 7°C, 0.4629 N/cm2/day at a temperature of 27°C, and 2.2728 N/cm2/day at a temperature of 27°C.

The working system in the boiler is that heat is channeled to boiler water which will then form steam. Water has an important role in the boiler, if the water used is not according to standards it will cause problems such as scale, corrosion, deposits, carry over and other specific problems. In general, the water fed to the boiler contains a high content of TDS and other dissolved and insoluble solids in it. From this research it is known that during April, May and June the highest blowdown rate occurred on April 12, 2022, namely 2183.76 kg/hour and for the lowest blowdown rate occurred on June 7, 2022, namely 684.91 kg/hour. The highest blowdown time occurred on 12 April 2022, which was 0.74 minutes/hour or equivalent to 44.4 seconds, and the lowest blowdown time occurred on 07 June 2022, namely 0.23 minutes/hour or equivalent to 13.8 second.

Glucomannan is a water-soluble fiber that can be extracted using polar solvents and precipitated using non-polar anti-solvents. Selecting the best extraction time and using the anti-solvent ratio could increased the yield of glucomannan. The used of anti-solvent Isopropyl alcohol (IPA) had a lower dielectric constant compared to ethanol, so it is more non-polar. An aim of this research was to obtain the best yield from a combination of extraction time treatment and the ratio of IPA as anti-solvent. The design used was a randomized complete factorial design (RALF) with two levels that is extraction time (1, 2 and 3 hours) and the ratio of porang flour to isopropyl alcohol (1:10, 1:15 and 1:20). The results showed that the interaction of extraction time and IPA anti-solvent ratio had a significant effect on the yield of glucomannan. The interaction of the 2 hour extraction time treatment with the anti-solvent ratio (1:15) produced the best glucomannan yield that is 66.69%. The results of FTIR testing of porang flour and glucomannan extraction results showed a shift in the wave number for each vibration, especially in the fingerprint area.

Propolis has thermostable properties with a melting point of 60oC – 65oC, so it does not require high temperatures in the extraction process. The extraction process using MAE requires a faster time because the pressure and temperature can be controlled. This study used a factorial completely randomized design with 2 factors with 9 treatments and 3 replications. The data obtained were analyzed by analysis of variant (ANOVA). If there is a difference, it is continued with the DUNCAN multiple distance test.

Teh yang diminati konsumen adalah yang tidak terlalu bitter dan kurang astringency. Metode penyeduhan dapat memberikan persepsi atribut sensori yang berbeda. Profil sensori dan hedonik tisane karamunting (Tikar) dengan berbagai metode penyeduhan dievaluasi menggunakan quantitative descriptive analysis (QDA) dan uji hedonik. Perbedaan metode penyeduhan dengan rasio daun kering:air (7:100 atau 3:100 b/v) digunakan dalam penelitian ini, yaitu seduh panas konvensional (PKV7 dan PKV3), seduh dingin (DKV7), seduh panas dengan drip bag (PDB7), dan seduh panas dengan tea bag (PTB3). Tisane komersial dalam tea bag (PTK3) digunakan sebagai pembanding. Pemetaan profil sensori hasil uji QDA pada berbagai metode penyeduhan dianalisis dengan PCA yang dilanjutkan dengan OPLS-DA dan korelasinya dengan hasil uji hedonik dianalisis dengan OPLS. Hasil dari QDA menunjukkan bahwa Tikar memiliki 14 atribut sensori. Metode sensometrik berhasil memetakan Tikar berdasarkan metode penyeduhan, yaitu PKV7 memiliki aktribut sensori harshness, stew dan astringency, sedangkan metode lainnya (DKV7, PKV7, PKV3, PTB3) greenish color, brightness color, serta fruity, dan PTK3 bitter dan smoky.
