ABSTRAK Pengolahan jahe merah dalam bentuk bubuk merupakan salah satu cara untuk mengawetkan hasil panen jahe merah yang memiliki kadar air yang tinggi. Pengolahan jahe merah dalam bentuk bubuk perlu dilakukannya pengeringan pada bahan sehingga mampu mengeluarkan kandungan air yang terdapat pada bahan. Dalam pengeringan suatu bahan suhu dan ketebalan merupakan hal berpengaruh pada pengeringan. Tujuan dari penelitian ini yaitu untuk mengetahui karakteristik pengeringan, sifat fisik bubuk jahe merah serta perlakuan yang menghasilkan kualitas bubuk jahe kering yang paling baik dengan variasi suhu dan ketebalan irisan selama pengeringan. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) faktorial dengan dua faktor dan tiga kali ulangan. Faktor yang pertama yaitu suhu pengeringan 50oC, 60oC, dan 70oC dan faktor kedua yaitu ketebalan irisan jahe merah 1 mm, 3 mm, 5 mm. Parameter yang diamati yaitu kadar air, kerapatan curah, sudut curah, indeks keseragaman, dan laju penurunan kadar air jahe merah. Dari hasil penelitian menunjukkan bahwa interaksi antar perlakuan suhu dan ketebalan irisan memberikan pengaruh yang signifikan terhadap parameter kadar air, kerapatan curah, sudut curah, dan laju penurunan kadar air jahe merah. Selanjutnya perlakuan terbaik diperoleh pada perlakuan (N3S5) dari jahe merah yang dikeringkan dengan ketebalan irisan 3 mm yang dikeringkan dengan suhu 50oC dengan nilai kadar air 10,05% bb, kerapatan curah 790Kg/m3, sudut curah 43,34o. ABSTRACT  Processing red ginger in powder form is one way to preserve the red ginger crop, which has a high moisture content. Processing of red ginger in powder form requires drying of the material so it can remove the water content in the material. In drying a material, the temperature and thickness influence drying. The purpose of this study was to determine the drying characteristics, the physical properties of red ginger powder and the treatment that produced the best dry ginger powder quality with variations in temperature and slice thickness during drying. The design used in this study was a factorial randomized block design (RBD) with two factors and three replications. The first factor is the drying temperature of 50oC, 60oC, and 70oC and the second factor is the thickness of the red ginger slices 1 mm, 3 mm, 5 mm. The parameters observed were moisture content, bulk density, angle of bulk, uniformity index, and rate of reduction in water content of red ginger. The results showed that the interaction between the temperature treatments and the thickness of the slices had a significant effect on the parameters of moisture content, bulk density, angle of bulk, and the rate of reduction in water content of red ginger. The best treatment was obtained in treatment (N3S5) of dried red ginger with a thickness of 3 mm slices dried at a temperature of 50oC with a moisture content value of 10.05% bb, bulk density 790Kg/m3, angle of bulk 43.34o.

This study aimed to assess the drying characteristics of red ginger under sun drying method and by using Hohenheim type dryer. This study used a non factorial randomized block design with drying method at 2 levels, namely the sun drying method (B1) and Hohenheim type dryer (B2).The results showed that the average temperature drying in Hohenheim type dryer is higher than the average temperature of sun drying method, while the relative humidity in the dryer is lower than the relative humidity of sun drying method. The weight loss and the drying rate of red ginger dried by using Hohenheim type dryer is higher than that of sun drying method. The moisture content of red ginger dried by using Hohenheim type drier (19.84%) was significantly lower than that of sun drying method (37.02%). Drying method did not affect the rate of contamination on both methods. However, red ginger dried by using Hohenheim type drier has brighter colour than that of sun drying method. Therefore, it can be concluded that the drying process by using Hohenheim type drier was better than that of sun drying method.

Six different Japanese Maples (Acer palmatum) cultivars `Water Fall', `Burgundy Lace', `Crimson Queen', `Oshio-Beni', `SangoKaKu', and `Bloodgood' from Monrovia Nursery were planted in a randomized block design on 4 June 1997 at the The Morton Arboretum. Leaf heat tolerance was evaluated by measuring ion leakage of the leaf tissue at 25–60 °C in July, Aug., and Sept. 1997. The LT50 (the temperature at which 50% of the tissues were injured) of all the cultivars were higher in July (≈53 °C) and were lower in September (≈47 °C). Water content of the leaf tissues were higher in July compare to August and September and were not related to heat tolerance of most cultivars. Stem cold hardiness was performed by artificial freezing tests in Oct., Dec., and Feb. 1997/98. The Lowest Survival Temperature (LST) for the most hardy to least hardy cultivars in October and December were: `Burgundy Lace' (–15, –27 °C), `Bloodgood' (–18, –24 °C), `Oshio-Beni' (–15, –24 °C), `Crimson Queen' (–15, –18 °C), `Water Fall' (–9, –18 °C) and `SangoKaKu' (–9, –12 °C), respectively. Growth, dormancy development, spring budbreak and performance of these cultivars will be compared.

This work aimed, to evaluate the structural behavior of Oxisols based on the least limiting water range (LLWR) and establish relations with corn crop. The experiment was carried out in a randomized block design with five treatments and four replications. Soil samples collected at the layer of 0-0.20 m depth in a Haplustox (LVd) and an Eutrustox (LVef) were used. The compaction treatments consisted of T0= no additional compaction; T1 and T2= two and four passes with a 4 t tractor, respectively; T3 and T4 = two and four passes with a 10 t tractor, respectively. The range of LLWR variation in the LVd was the lowest one and varied from 0.01 to 0.04 m3 m-3, whereas in the LVef varied from 0.03 to 0.13 m3 m-3 for the critical soil penetration resistance (PRc) of 2 MPa. It was observed that critical bulk density (BDc) values were 1.76 and 1.40 Mg m-3 in the LVd and the LVef, respectively. The highest frequency of bulk density (BC ≥ BDc) occurred from the T1 to T4 (LVd) and from the T2 to T4, however, a reduction in corn yield was not observed. The determination of the LLWR was efficient and complementary for identifying more favorable or more impeditive conditions to compaction in the LVef for the corn crop development in relation to the LVd.
