Abstract

Banana is a potential commodity to gain foreign currency since its export has tended to increase yaer by year. Postharvest handling of banana is very important in order to maintain high quality of the products. Artificial ripening is one method applied to control the rate of ripening and in the other side to guarantee the uniformity of quality. Teperature in the ripening chamber plays an important role since it directly influences respiration rate of the products. This research is aimed to apply fuzzy control to regulate the temperature, which is set in order to get better quality of the product. Yhe objective of the fizzy control is to set the temperature into 4 (four) decreasing steps : 1) 24"C. 2)22.5"C 30 21.5 "C and 4) 24 "C each for 24 hours. Respiration rate during these periods are 0.0866 ml CO2/kg/h become 0.06054 ml CO2/kg/h or 3.1716 ml O2/kg/h/ become 0.7016 ml O2/kg/h.

Abstract

A mathematical model was developed to predic O2 and CO2 gaseous concentration for fresh vegetables under modified atmosphere packaging Mathematical models were developed by assump that the slides basin packing it permaeble and the bottom package is imperable.Verification of the model were done by using the experimental data of read chilli, carrot and tomato, the models were generally significant enough to predict the gaseous condition of inside package for fresh vegetables products under MAP.Key words : MAP, prediction models, shelf life, permabilitas, laju respirasi.

Abstract

Orange (Citrus grandis L.) is one of horticulture commodity which is consummed because of its delicious taste and plenty vitamins and minerals that is required by the humm body. The respiration rate of the minimally processed of orange at 10, 15 and 27.5 OC were 8.10, 13.24 and 28.212 ml/kg. h, re.jp,pectivily. The respiration rate of whole (unpeeled) orange at the same storage temperature were 10.15, 19.13 and 42.28 ml/kg. h, respectivily.

Abstract

The aims of this research are: I) to identzJL the changes ofphysiologic characteristics of cashew apples during storage under MAP system; 2) to verzfv the changes of their quality during storage; and 3) to establish the optimum gaseous compotition range in the MAS system. To completed the research, the experimen was conducted by four steps activities as follows: I) the measurement of respiration rate; 2) establishment of the range of modijied atmosphere storage for cashew uppels; 3) cojitputingthe packaging area and selecting the kind of plastic film; 4) prediction of shelf lge for cashew appels during srorage under MAP system.

Abstract

ABSTRAK Pemisahan biji dan daging buah asam merupakan tantangan dalam pemecahan masalah saat ini yaitu teknologi mekanisasi atau mesin pertanian. Penelitian ini bertujuan membuat suatu kajian dasar mekanisme pemisahan biji buah asam (Tamarindus indica sp) dalam rangka perancangan mesin pengolah asam tanpa biji. Model awal dari alat mesin pemisah biji asam dengan mempelajari konsep perancangan terhadap kinerja unit penyayat dan pemisah biji asam. Perancangan awal bagian pemisahan biji dan daging buah terdiri dari unit penyayatan untuk menyayat buah  asam sebelum buah asam ke unit pengupas yang terdiri dari dua buah silinder pengupas. Unit pengupas dipasang sejajar  sehingga mampu melewatkan daging yang terpisah dan tetap menahan biji asam yang akan dipisahkan dengan unit pemisah biji. Model prototipe awal dari alsin pemisah biji asam telah berhasil dibuat, pada uji model dilakukan pengukuran kecepatan putar dari poros pengupas pada rpm 1065 yang efektif pada tingkat beban yang diuji yaitu pada 100 gram, 200 gram, dan 300 gram. Pengukuran torsi pengupasan  menunjukan nilai torsi terjadi peningkatan yang cukup signifikan  dengan naiknya tingkat beban untuk semua perlakuan, nilai torsi terbesar terjadi pada kecepatan putar 890 rpm dengan nilai torsi sebesar 1,45 Nm pada tingkat beban yang diberikan sebesar 300 gram. Sedangkan pada kecepatan putar 1220 rpm nilai torsi yang terjadi adalah 1,17 Nm dengan tingkat beban yang di berikan sebesar 300 gram. Kata Kunci : Kajian dasar, kinerja, buah asam, pemisah biji  ABSTRACT The process of fruit and seed separation on Tamarind is a challenge for agricultural mechanization technology that must be solved. The purpose of this study is to develop a basic study of the Tamarind fruit separation mechanism (Tamarindus indica sp) as a part of design process on Tamarind seedless processing machine. Initial design of Tamarind seeds separation machine was made by studying the work of  slashing unit and seed separation unit. Tamarind seedless processing machine consist of slicer and peeler. The slicer function is to slice the fruit before it sent into peeler unit which contains two cylindrical peeler. The peeler unit installed parallel so it let through the fruit pulp but still hold the Tamarind seeds that had been separated by the separator unit. Tamarind seeds separation prototype model has been succesfully made. Model testing was done by measuring the rotary speed of spindle peelers on 1065 rpm which considered work effectively for the test load of 100 grams, 200 grams and 300 grams. Further, shaft torque measurements in the process of peeling showed a significant increase in value and it is proportional to the increase in load level for all treatments. Greatest torque happened at 890 rpm rotation speed with a value of 1.45 Nm at 300 gram load. While the rotary speed of 1220 rpm produce 1.17 Nm torque at 300 grams load. Keywords : Basic study, performance, tamarind, seed separator
