Abstract

Penyimpanan pada suhu dingin merupakan salah satu cara mempertahankan kesegaran ubi jalar ungu Ayamurasaki. Pendinginan akan memperlambat atau mencegah terjadinya kerusakan yang tidak diinginkan tanpa menimbulkan gangguan pada proses pematangan dan memperlambat perubahan yang tidak diinginkan selama penyimpanan suhu dingin. Penyimpanan suhu dingin khususnya pada suhu 40C dapat memperpanjang masa hidup jaringan-jaringan dalam bahan pangan tersebut karena aktivitas respirasi menurun dan menghambat aktivitas mikroorganisme. Tujuan penelitian ini untuk mengetahui Aktivitas Antioksidan Ubi Jalar Ungu (Ipomoea Batatas Var Ayamurasaki) Selama Penyimpanan Suhu 40C. Hipotesis yang dapat diambil dari penelitian ini adalah: Diduga lamapenyimpanan suhu dingin mengalami peningkatan terhadap kandungan senyawaantioksidan khususnya senyawa antosianin yang terdapat dalam ubi jalar ungu(Ayamurasaki). Tempat dan waktu penelitian. Penelitian ini dilakukan di Laboratorium Fakultas Pertanian Universitas Katolik Widya Karya Malang pada bulan Maret 2014.

Abstract

Antioksidan dalam pengertian kimia adalah senyawa pemberi elektron (electron donor), dalam arti biologis antioksidan adalah semua senyawa yang dapat meredam radikal bebas dan reactive oxygen species (ROS) yang bersifat oksidan termasuk protein pengikat logam. Antosianin merupakan senyawa flavonoid yang memiliki kemampuan sebagai antioksidan. Flavonoid merupakan senyawa metabolit sekunder yang ada pada tanaman. Perkecambahan adalah serangkaian peristiwa penting yang terjadi sejak biji dorman sampai menjadi bibit yang sedang tumbuh (Copeland, 1976). Perkecambahan dapat meningkatkan daya cerna bagi manusia karena adanya proses yaitu katabolisme. Tujuan dari penelitian ini adalah untuk mengetahui aktivitas antioksidan ubi jalar ungu Ipomea batatas var Ayamurasaki selama masa perkecambahan. Senyawa antioksidan yang dimaksud adalah antosianin. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) karena bersifat homogen. Perlakuan perkecambahan dengan terdiri dari 4 (empat) level: perkecambahan selama 0 hari (kurang dari 24 jam), perkecambahan selama 5 hari, perkecambahan selama 10 hari dan perkecambahan selama 15 hari. Variabel penelitian adalah aktivitas antioksidan, antosianin dan kadar gula. Untuk mengetahui pengaruh dari masing –masing perlakuan dilakukan uji F (F tabel 5% dan 1%) dan untuk mengetahui perbedaan masing-masing perlakuan digunakan uji Beda Nyata Terkecil (BNT).Hasil analisis ragam menunjukkan bahwa perkecambahan berpengaruh sangat nyata pada taraf 1% untuk kadar gula, kadar antosianin dan aktivitas antioksidan. Level dari perlakuan perkecambahan yang direkomendasikan untuk dilakukan sehingga menghasilkan kadar gula, kadar antosianin dan aktivitas antioksidan yang tinggi adalah level 4 (perkecambahan selama 15 hari) yang menghasilkan kadar gula 18%, antosianin 199,680 gr/kg dan aktivitas antioksidan 81,424%. Kata Kunci: perkecambahan, antioksidan, antosianin, kadar gula.

Abstract

Coffee is a commodity with a very important role in the national economy. International Coffee Organization said that Indonesia is the sixth rank in the world's largest coffee consumption. The climate in Indonesia is suitable for commercializing coffee plants, but the ability of farmers in marketing strategy to is still low so, the income obtained by coffee farmers is not optimum. In Malang, there are four coffee producing regions, one of it is Batu City which produces Arabica coffee. Arabica coffee has a higher selling value than robusta coffee and liberika. Coffee farmers in Batu City are spread in five sub-districts. The number of samples used in this study are twelve coffee farmers because in Batu there are twelve coffee producers who cultivated, processed into coffee powder, and marketed their own coffee products to consumers with diverse income and varied strategy designs in marketing process. The determination of the sample in this study is non probabilily sampling with purposive sampling. To measure the marketing mix is used a Likert scale, while to measure the income of coffee farmers an open questionnaire is used that will be distributed to farmers. The method is used descriptive analysis to determine the marketing mix strategy used by farmers, cost and income analysis to determine farmers' income and multiple linear regression analysis to determine the effect of marketing mix strategies on the income of coffee farmers in Batu City. The results showed that the marketing strategy used by coffee farmers in Batu City are 7p marketing mix strategy including products, prices, places, promotions, people, physical evidence and processes. The average farmer income per one coffee tree is Rp. 412.500 with an average total cost of Rp. 127.824, the average income received by coffee farmers in Batu City per one coffee tree is Rp. 284.676. Variable marketing mix 7p has a simultaneous and partial effect on income.

Abstract

Banana Ledre is a food product processed from banana which is a type of snack. Processing of agricultural products aims to add value to this product because it can be sold at a higher price than fresh product. Banana ledre made by U.D. Dua Putri Dewi, Malang City uses several inputs other than banana as raw material. In the production process, efficiency in the use of inputs is an important thing that needs to be considered by entrepreneurs. Technical efficiency is a measure of how well resources or production inputs are used in the production process to provide optimal results. This study aims to analyze the technical efficiency of the use of production inputs consisting of raw materials, labor, and wages in producing banana ledre. The method used to analyze technical efficiency is Cobb Douglas production function regression analysis. In order to do the analysis, the production function is transformed into a linear model. The research hypothesis was tested by comparing the value of bi with a value range of 0-1. The results showed that the use of production cost factors was not efficient. This is based on the b1 value of 1.474 where this value is greater than 1. The use of working hours is inefficient based on the b2 value (-0.515) which is less than 0. The use of work wages is efficient based on the b3 value (0.059) which ranges from 0-1. Based on these results, entrepreneurs need to review the use of raw material costs and working hours in the production process. Things that can be done include finding raw material suppliers that offer lower prices and optimizing working hours as efficiently as possible.
