As an Arabica coffee producer, the Gayo community is constrained by the relatively cold local temperatures in Central Aceh and the simple technology used for the coffee drying process. The average daily temperature is 23-29 ° C. The material used in this study was coffee beans which were processed by the semi-wet method of 9kg. Research parameters include drying temperature, relative humidity, moisture content and yield. The results showed that the drying temperature using a Hohenheim dryer is much higher around 10-20 ° C than the drying temperature by drying. The process of drying pumpkin coffee until it can be ground needs 12 hours, which is 8 hours on the first day and 4 hours on the second day. While the process of drying stage 2 takes 16 hours to produce rice coffee with a moisture content of 9.32%. The quality of rice coffee produced is good with water content that meets SNI standards, does not smell bad, and is not contaminated. The yield of pumpkin coffee-based rice coffee is 35%.

Abstrak.Mutu cabai kering perlu ditingkatkan sehingga masyarakat mau menggunakan cabai kering sebagai pengganti cabai segar. Penelitian ini bertujuan untuk mengkaji mutu cabai merah kering yang diberi perlakuan blanching dengan variasi konsentrasi larutan natrium metabisulfit sebelum proses pengeringannya. Variasi konsentrasi yang diuji adalah 0%, 0,2% dan 0,3%. Pengeringan cabai merah dilakukan dengan menggunakan alat pengering terowongan surya tipe Hohenheim termodifikasi. Proses pengeringan berlangsung selama 3 hari dengan rentang waktu yang berbeda yang diakibatkan oleh tahapan perlakuan pra pengeringan yaitu blanching dan kondisi hujan, dimana total waktu pengeringan adalah 10 jam. Hasil penelitian menunjukkan bahwa selama proses pengeringan terjadi fluktuasi iradiasi surya dimana rata-rata iradiasi surya tertinggi diperoleh pada hari ketiga yaitu sebasar 383,73 W/m². Pengeringan menggunakan alat pengering tipe Hohenheim berlangsung dengan rentang temperatur pengeringan 42-62 ºC, RH 26-78%, dan kecepatan udara yang sangat rendah. Peningkatan konsentrasi larutan natrium metabisulfit mempercepat penurunan kadar air sehingga mempercepat proses pengeringan.Vitamin C cabai kering menurun setelah pengeringan sebagai akibat terpaparnya cabai kering terhadap temperatur pengeringan. Rendemen cabai kering menurun dengan peningkatan konsentrasi larutan natrium metabisulfit. Berdasarkan analisis warna, warna tercerah diperoleh pada cabai merah kering perlakuan blanching dalam larutan natrium metabisulfit dengan konsentrasi 0,2%.Increasing quality of dried red chili Pepper by Blanching treatment in solutionof natrium metabisulfiteAbstract.The quality of dried red chili pepper have to improve so that the people will use dried red chili pepper as alternative to fresh red chili pepper. The study aimed to evaluate the quality of dried red chili pepper after blanching in solution of sodium metabisulfite at different concentration i.e. 0, 0.2, and 0.3%. The drying process was done by using modified solar tunnel Hohenheim type dryer.The complete drying process needed 3 days at different durration and the total time used was about 10 hours due to the preparation of blanching treatment and rainy day. Results showed that during the drying process there was high fluctuation of solar irradiation, where the highest average of solar irradiation occurred on the third day, 383.73 W/m². The drying temperature ranged from 42 to 62 ºC and the relative humidity ranged from 26 to 78%. However the air velocity in the drying chamber was very low. The increase of concentration of sodium metabusulfite solution caused the higher water loss therefore shortern the drying process. The vitamin C of dried red chili decreased at all concentration treated due to the high temperature during drying process. The yield of dried red chili decreased as the increase of concentration of sodium metabusulfite solution. The bright colour of dred red chili was gained by using concentration of sodium metabusulfite solutionat 0.2%.

Efficiency Analysis in Drying System for Rosella (Hibiscus sabdariffa L) Using Cabinet Type DryerABSTRACT. Drying is one of the most important process in producing a good quality of rosella tea. The study was aimed to evaluate the drying efficiency of rosella tea by using a cabinet dryer. The source of energy for the dryer was from the burning of charcoal. The charcoal was prepared from the coconut shell since it was abundant biomass product. About 7.5 kg of fresh rosella flower was dried for 17 hours. The total of charcoal consumed was 17 kg. The moisture content of rosella flower was reduced from 90 to 12 %. The analysis showed that the total of energy produced from the burning of 17 kg charcoal was 309.4 MJ, whilst the total energy needed to dry the flower was 15,72 MJ. Therefore, the drying efficiency was still low about 4.58%. Further study is recommended to improve the drying efficiency for example by the use of deeper depth of dried products between 2 and 6 cm as well as by improving the system of hot air circulation.

Abstrak. Informasi umur simpan tomat sangat penting untuk proses penanganan pasca panennya sehingga dapat mengurangi resiko kerugian yang dihadapi oleh para petani dan pedagang. Penelitian ini bertujuan untuk mengetahui apakah model Arrhenius dan Q10 dapat digunakan untuk menduga umur simpan tomat berdasarkan nilai total padatan terlarut (TPT). Tomat segar terbaik yang diperoleh dari pasar induk disimpan dengan 3 variasi suhu ekstrim yaitu 50˚C, 60˚C dan 70 ˚C. Selama penyimpanan tersebut dilakukan pengamatan nilai TPT setiap 1 jam sekali, sampai keadaan tomat sudah tidak layak untuk dikonsumsikan lagi. Peralatan yang digunakan adalah refraktometer digital. Analisis model Arrhenius dilakukan dengan pendekatan persamaan linier. Pendugaan umur simpan dilakukan dengan metode Q10. Hasil penelitian menunjukkan bahwa model Arrhenius perubahan TPT tomat adalah k = 7,46x1012. e -8666/T . Energi aktivasi perubahan TPT buah tomat adalah 17.158 kal/mol. Nilai Q10 diperoleh sebesar 2,18. Pendugaan umur simpan dapat dilakukan dengan pendekatan ini baik menggunakan basis suhu penyimpanan 10 maupun 30 °C. Umur simpan tomat pada suhu 30 °C adalah 4,4 dan 5 hari, sedangkan umur simpan tomat pada suhu 10 °C adalah 21 dan 23,8 hari. Perlu penelitian lanjutan untuk menduga umur simpan tomat menggunakan parameter mutu lain seperti vitamin C dan kekerasan untuk meningkatkan validitas hasil pendugaan umur simpannya. The prediction of Tomato shelf life Based on Its Total Soluble Solid by Using Arrhenius and Q10 Model Abstract. The information about shelf life of tomato is necessary for its post harvest handling to reduce the loss facing by farmers and sellers. The study aimed to observe that the Arrhenius model and Q10 can be used to estimate the shelf life of tomatoes based on its total soluble solid (TSS). The fresh tomatoes obtained from the market were stored at three extreme temperatures i.e. 50˚C, 60 ˚C, and 70 ˚C. During the storing, the TSS was analyzed every hour, until the tomatoes quality was decreased. The TSS was observed by using refractometer. The Arrhenius model were evaluate through the TSS model in linier model. The shelf life estimation were calculated by Q10 method. Results showed that the Arrhenius model of TSS changes in tomatoes was k = k = 7.46x1012. e -8,666/T. The energy activation of TSS changes was about 17,158 kal/mol. The Q10 value was 2.18. The estimation of tomato shelf life can be run successfully by using the Arrhenius and Q10 approach, both at storage temperature basis of 10 and 30 °C. The shelf life of tomatoes at storage temperature 30 were 4.4 and 5 days, respectively, whereas at storage temperature 10 °C were 21 and 23.8 days, respectively. Therefore it is recommended for the further study to evaluate the other quality parameter changes such as vitamin C and hardness to improve the model.

Abstrak. Lengkuas (Alpinia galanga) adalah salah satu tanaman penting bagi masyarakat Indonesia. Tanaman ini dapat digunakan untuk bumbu masakan dan obat herbal. Tujuan kajian ini adalah untuk menduga umur simpan lengkuas segar dengan menggunakan model Arrhenius. Lengkuas segar yang baru dipanen dibersihkan dan dipotong-potong dengan ukuran 2cm, kemudian disimpan pada suhu 5, 10 dan 28°C. Evaluasi dilakukan oleh 25 orang panelis dengan menggunakan skala hedonic dari sangat suka sampai sangat tidak suka terhadap warna, kesegaran, aroma dan tekstur. Parameter yang diamati adalah kadar air dan kadar sari larut dalam air. Parameter tersebut diamati dalam interval 3 hari selama 21 hari atau sampai sampel dinyatakan tidak disukai oleh panelis pada salah satu kriteria hedoniknya. Hasil penelitian menunjukkan bahwa pad asuhu 28°C, lengkuas dapat disimpan selama 3 hari, sedangkan pada suhu 10 dan 5°C, lengkuas dapat disimpan selama 12 dan 21 hari. Energi aktivasi (EA) dan tingkat perubahan mutu (Q10) karena kadar sari larut dalam air lebih besar dari energi aktivasi (EA) dan tingkat perubahan mutu (Q10) karena kadar air lengkuas. Namun demikian, kedua parameter tersebut tidak tepat digunakan untuk menduga umur simpan lengkuas. Shelf-Life Prediction of Galanga by Using Arrhenius Model Based on Its Moisture and Water Soluble Extract Content Abstract. Galanga (Alpinia galanga) is one of important plants for Indonesian people. It can be used as spices and also as herbal medicine. The aim of this study is to predict the shelf-life of fresh galanga by using Arrhenius model. Fresh harvested galanga, which was cleaned and chopped at width about 2 cm, was stored at temperatures 5, 10, and 28°C. The evaluation was done by 25 respondents by using hedonic scale from the range of like very much until dislike very much. This hedonic evaluation was assessed, based on colour, freshness, aroma, and texture. Parameters observed were moisture and water soluble extract content. These parameters observed at interval 3 days for 21 days or until the samples were rejected by respondents for at least one of hedonic factors. Results showed that at temperature 28°C, galangal can be stored for 3 days. However, at temperature 10 and 5 °C, galangal can be stored for 12 and 21 days, respectively. The energy act ivation (EA) and the rate of quality change (Q10) due to water soluble extract were higher than those of water content. Nevertheless, these two parameters cannot be used in prediction the shelf-life of fresh galanga.

Umur simpan Pliek-U dapat ditentukan dengan persamaan tT1=32 .1,214(∆T/10).Shelf-life estimation of Pliek-U based on moisture changes by using Arrhenius and Q10 approachAbstract. The study aimed to predict the shelf-life of Pliek-U by using Arrhenius and Q10 approach. About 6 samples of Pliek-U, already known its moisture, were exposed to high temperatures of 50, 60, dan 70ºC to reach degradation quality characterized by color and odor changes. The alteration of weight was also observed at interval of 30minutes. Based on these data, the changes of moisture were calculated and the trend was drawn on a XY scatter chart. The gradien of the chart was the reaction rate of quality degradation (k). Then, the Arrhenius model was constructed by plotting ln k and 1/T (K) into a graph. Lastly, the Q10 and shelf-life were calculated by using assumption that the shelf-life at room temperature was about 32 months. Results showed that the k-value and R-square of Pliek-U at 50˚C was 0.0621 and 15.52%, respectively. The k-value and R-square of Pliek-U at 60˚C was 0,0826 and 67,9%, whereas the k-value and R-square of Pliek-U at 70˚C was 0,0877 and 54,39%. The Arrhenius model of Pliek-U based on moisture changes was k = 27,454. e-1.925(1/T) and R-square was 91.47%. The Q10-value of Pliek-U was 1,214 and the shelf-life of Pliek-U can be adjusted by using the model tT1=32 .1,214(∆T/10).

Abstract. Minyak simplah adalah produk lokal Aceh dari proses fermentasi kelapa yang mempunyai manfaat seperti minyak kelapa murni (VCO). Tujuan penelitian ini adalah untuk mengetahui pengaruh pemanasan energi mikrowave terhadap kualitas minyak simplah berdasarkan variasi volume minyak. Metode yang dilakukan adalah memanaskan minyak simplah dalam mikrowave oven frekuensi 2,450 MHz selama 60 detik dengan energi 800W pada variasi volume yakni 20, 40,dan 60 ml, dengan 3x ulangan. Pengamatan dilakukan terhadap suhu, kadar air, derajat keasaman, asam lemak bebas, bilangan peroksida dan warna. Hasil penelitian menunjukkan bahwa perlakuan variasi volume minyak pada pemanasan mikrowave selama 60 detik meningkatkan suhu minyak secara signifikan, namun perlakuan tersebut tidak memberikan pengaruh nyata terhadap kadar air, pH, asam lemak bebas dan bilangan peroksida. Kualitas minyak simplah sebelum dan setelah pemanasan dengan mikrowave belum memenuhi standar sehingga penelitian lanjutan sangat diperlukan untuk mengkaji kemungkinan peningkatan kualitas minyak menggunakan energi mikrowave dengan memperlama waktu pemanasan.The Influence of Oil Simplah Volume to Its Quality under Microwave HeatingAbstract. The simplah oil, contained a lot of benefits as virgin coconut oil (VCO), is traditionally produced during fermentation of coconut by Acehnese. The purpose of this study is to determine the influence of microwave heating on the simplah oil quality based on the variation of its volume. The study was conducted by heating the simplah oil by using a microwave oven at frequency of 2.450MHz for 60s at power level 800W under the variation of oil volume i.e. 20, 40, and 60 ml in three replications. The parameters observed were temperature, water content, degree of acidity, free fatty acids, peroxide number and color. Results showed that the variation of oil volume after microwave heating had significant effect on temperature, but did not significantly influence the rest parameters. Since the quality of simplah oil before and after treatment did not meet the standard yet, it is very important to conduct the further study by extending the exposure time of the oil under microwave heating.
