Abstract

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.

Penggunaan kompos sebagai pupuk organik merupakan upaya implementasi sistem low external input on sustainable agriculture (LEISA), penerapan sistem ini dapat (1) meningkatkan proses perbaikan kesehatan lahan, (2) peningkatan kesuburan lahan, dan (3) perbaikan sifat fisik tanah. Permasalahan utama di beberapa SIMANTRI proses pembuatan kompos belum menghasilkan kompos yang memenuhi standar SNI, terutama karena penggunaan bahan baku yang belum memenuhi standar. Penelitian ini bertujuan untuk mengetahui perbandingan komposisi bahan yang terbaik antar kotoran sapi dan kotoran ayam untuk membuat kompos sesuai dengan standar kualitas kompos. Percobaan dengan 5 pelakuan yaitu KS= kotoran sapi, KA= kotoran ayam, KSKA 2:1= kotoran sapi: kotoran ayam 2:1, KSKA 3:1 = kotoran sapi : kotoran ayam 3:1, KSKA 4:1 = kotoran sapi : kotoran ayam 4:1. Analisa dilakukan di laboratorium Ilmu Tanah Fakultas Pertanian Universitas Udayana. Proses pengomposan berlangsung selama 2 bulan dengan suhu pengomposan mulai dari 22 0C sampai 53 0C dan pengomposan pada pH mulai dari 4 sampai 7. Bentuk fisik kompos sudah menyerupai tanah yang berwarna hitam kecoklatan. Secara umum, kualitas kompos yang dihasilkan dari lima diperlakukan sesuai dengan SNI 19-7030-2004 dengan hasil akhir kotoran sapi berbanding kotoran ayam 2:1. Suhu 25.71; pH 6.91; karbon 11.14 % ; nitrogen 0.66 % and C / N ratio 15.82 %. The use of compost as organic fertilizer is an effort to implement low external input on sustainable agriculture (LEISA) system, the application of this system can (1) improve the process of land health improvement, (2) increase of soil fertility, and (3) improvement of soil physical properties. The main problem in some SIMANTRI is the process of composting did not produce a good quality compost that meets SNI ( Indonesian National Standard), mainly due to the use of raw materials that have not met the standard. This study aimsed to determine the best composition between cow manure and chicken manure to make compost in accordance with compost quality standards. Experiments trough 5 treatments were KS = cow manure, KA = chicken manure, KSKA 2: 1 = cow manure: chicken manure 2: 1, KSKA 3: 1 = cow manure: chicken manure 3: 1, KSKA 4: 1 = cow manure : chicken manure 4 : 1. The compost analysis compost was conducted in the Soil Science Laboratory of Faculty of Agriculture Udayana University. The composting process has done for 2 months with composting temperatures rangied from 22 0C to 53 0C and composting at pH rangied from 4 to 7. Physical form of compost already resembles a brownish-black soil. Generally, the quality of the compost produced has fullfiled with SNI 19-7030-2004 with the final result of cow dung versus 2: 1 chicken feces. Temperature 27.04 0C, pH 6.85, Carbon 11.14%, Nitrogen 0.64% and C/N ratio of 15.82%.
