Abstract Past research shown that coconut oil can be used directly in Diesel engine by adding a heating element in the fuel delivery system. This study aims to evaluate the performance of a hand tractor pull using pure coconut oil fuel. The Diesel engine of the tractor was equipped with a fuel heater installed on the mufler. Traction performance parameters tested were wheel slippage, drawbar pull, forward speed and drawbar power on the path of concrete and soil. Besides, the tractor was also tested on plowing using a moldboard plow. The test results on the concrete track showed that the maximum drawbar pull was 1.21 kN generated at a speed of 0.92 m/s, with a maximum drawbar power of 1.21 kW at the wheel slip of 10.87%. While the drawbar pull on the soil track was 1.37 kN at a speed of 0.79 m/s, with a maximum value of 0.71 kW drawbar power when wheels slip 22.25%. The results of tillage test showed that field efficiency was 84.66%, which was not much different from the test result using Diesel fuel.

AbstractThis research was undertaken to determine the effect of length in heat shock and edible coating as prestorage treatment on Chilling Injury (CI) symptom reflected by ion leakage induced and quality properties in tomato (Lycopersicon asculantum Mill.). Heat Shock Treatment (HST) was conducted at three different levels of length, which were, 20, 40 and 60 min. Edible coating was conducted using aloe vera gel. The result showed that HST and Aloe Vera Coating (AVC) were more effective to reduce CI symptom at lower chilling storage. Prolong exposure to heated water may delay climacteric peak. The length of heat shock; AVC treatment and low temperature storage significantly affected the tomato quality parameter but not significantly different for each treatment except weight loss. HST for 20 min at ambient temperature was significantly different to other treatment.Keywords: ion leakage, chilling injury, climacteric, shelf-lifeDiterima: 2 Desember 2009; Disetujui: 22 Maret 2010

AbstractCultivation of tomato plant under hydroponics system in the greenhouse is suitable way to improve fruit quality since it is easier to control environmental parameters. In this system, water and nutrition are two important things for plant to growth. In the tropical area such as Indonesia, air temperature is main constraint in the plant production system. Increasing air temperature inside the greenhouse has positive correlation to the raising temperature of nutrient solution which affected to the ability of the plant to absord the nutrition. The effective way to anticipate increasing of its temperature is by using the cooling system of nutrient solution before circulated to the plant. This paper presented the application of Articificial Neural Network (ANN) to estimate the temperature of nutrient solution which was cooled on day-night time and circulated to the plant. ANN models, called time delay neural network, consist of 3 layers with 4 input nodes and 1 output node. As input model were t (time), Tg(i) (air temperature inside the greenhouse on time i), Tt(i) (temperature of nutrient solution in the tank on time i), Tb(i-1) (temperature of nutrient solution in the plant plots on time i-1) and as output model was Tb(i) (temperature of nutrient solution in the plant plots on time i). The model was developed well with validation result better than heat transfer model previously indicated by coefficient determination (R2) of 0.9498.Keywords: cooling, nutrient solution, hydroponic, tomato, artificial neural networkDiterima: 15 Juni 2010;Disetujui: 30 juli 2010

Abstract Chilling Injury is a major problem in storing mango fruit in low temperature wich is unavoidable in order to extend the shelf life of fruit. symptoms of chilling injury during storage associated with the change in pH due to ion leakage. Chilling injury can be detected during storage destructively, but it will require time and a lot of samples. Alternatively, the detection can be performed non-destructively by using near infrared (NIR). The purpose of this research is to build the NIR calibration models for predicting ion leakage relating with change in pH and the detection of chilling injury symptoms can be done through ion leakage storage. Reflectant NIR measurements conducted on mango fruit stored at a temperature of 8 ° C and 13 ° C. Determination of chilling injury symptoms was predicted based on change in pH and the rate of ion leakage. The analysis showed that NIR spectroscopy was able to predict the change in pH during storage of mango fruit at a temperature of 8 °C based on reflectance and PLS method. Moreover ion leakage could also be predicted properly through the pH of the NIR predictions.

AbstractIn this study, the chilling induced in Japanese cucumber (Cucumis sativus L.) stored at chilled temperature and the changes in its quality during storage period were examined. Change in ion leakage and pH were used as indicator of chilling injury symptopms. The sample of cucumber were stored at 5ºC (chilling) and 25ºC (non chilling). Percentage of ion leakage for cucumber stored at 5ºC was higher than that at 25 ºC at storage time of 3, 6 and 9 days. The increase in the rate of ion leakage at 5ºC indicates the chilling induced of cell membrane. The increasing tendency of pH was observed for cucumber stored at 5ºC with the value at storage time of 9 days were higher than that at 25ºC. The increase in pH could be thought as the change in acid content which indicate the occurrence of chilling injury. Changes in ion leakage and pH indicate the change in membrane permeability which related to chilling injury. Keywords: chilling injury, ion leakage, pH, Japanese cucumber, low temperature storage Abstrak Tujuan dari penelitian ini adalah untuk menganalisis terjadinya gejala chilling injury pada mentimun Jepang (Cucumis sativus L.) yang disimpan pada suhu rendah.

AbstractCNC machinery is widely used at various kind of industrial sector to manufacture of art products up to satellite products. Instead of its massive utilization in automotive and electronic industry which mostly use metallic component, wood working industry has been using it to produces furniture’s, merchandises, and other house ware products which apply light weight non-metallic low density material. High removalrate in wood machining process needs high speed application due to its low density material; however most of wood working CNC machine is built on heavy steel structure for both its supporting structure and moving structure. In fact, the raw material is much lighter than the carrier itself. Its wasteful dynamic movement causes energy loses and vibrations that effect on machining accuracy, live of cutting tool, andproductivity. This research applied new light weight composite material base on renewable resource of oil palm empty fruit bunch (EFB) natural fiber as filler material combine with polymer epoxy as it’s matrix to be constructed as moving mechanical structure of high speed 3D CNC woodworking machine to improve its dynamic performance. Comparative analysis showed that it has better dynamic performance on high speed machining process compared with traditional cast iron materialAbstrakMesin Perkakas CNC (Computerized Numerical Control) digunakan luas oleh industri untuk memproduksi mulai dari benda-benda seni kerajinan hingga untuk membuat satelit. Selain pemanfaatannya secara besar-besaran di industri otomotif dan elektronika yang umumnya menggunakan komponen logam, industri perkayuan telah banyak menggunakannya untuk memproduksi mebel, barang kerajinan, dan peralatan rumah tangga lainnya dengan mengaplikasikan bahan bukan logam seperti kayu yang berberat jenis rendah dan ringan. Tingkat pemotongan yang tinggi pada proses permesinan kayu membutuhkanpermesinan cepat akibat berat jenis bahannya yang rendah tersebut, namun mesin CNC perkayuan umumnya dibangun dengan struktur logam yang berat, baik untuk struktur penopang maupun struktur bergeraknya. Kenyataannya, bahan baku kayunya sendiri jauh lebih ringan ketimbang struktur yang menggerakkannya. Dinamika gerakan pada struktur bergerak yang berat ini menyebabkan pemborosandaya dan getaran berlebih yang mempengaruhi ketelitian, keawetan pahat potong, dan produktivitas. Penelitian ini mengembangkan bahan komposit ringan baru dengan memanfaatkan sumber terbarukan dari limbah tandan kosong kelapa sawit (TKKS) sebagai bahan pengisinya dengan matriks polimer epoxy untuk dibangun sebagai struktur bergerak mesin CNC perkayuan metode permesinan cepat 3 dimensi, untuk meningkatkan unjuk kerja dinamiknya. Analisa perbandingan menunjukkan bahan ini memiliki unjuk kerja dinamik lebih baik pada proses permesinan cepat ketimbang menggunakan besi tuang sebagai bahan tradisionalnya.
