Abstract

Identification of plant disease is an important step to decide how it will control. This paper discusses the design and development of an expert system for identification of 12 general diseases of red pepper plant (Capsicum annum L.). Disease identification in this software system was based on the visual symptom of disease(s) in various plant growth stages, similar to the standard rules in plant protection science. The prototype of this software system was implemented by EXSYS Professional for Microsoft Windows (WINEXSYS) version 5.0 and worked under Windows '95 operation system. This software system is user-friendly and equipped by image-visualization that describe disease symptoms.

Abstract

Penelitian ini bertujuan untuk mengembangkan model matematik dalam menduga sebaran suhu pad a penukar panas jenis pipa vertikal, serta menduga suhu udara pengering yang dihasilkan oleh penukar panas. Hasil penelitian ini diharapkan dapat memberi manfaat pad a perancangan alat penukar panas serta meningkatkan efisiensi dalam penggunaan bahan bakar pada penukar panas. Hasil simulasi menunjukkan bahwa laju pembakaran bahan bakar merupakanparameter penting dalam sistem penukar panas. Pada laju pembakaran bahan bakar 0.77 kg/jam, suhu udara pengering yang dihasilkan adalah 56.2 °e. Sedangkan pada laju pembakaran bahan bakar 2.32 kg/jam, suhu udara pengeringadalah sebesar 90.9 °e. Laju aliran udara pengering dan luas permukaan penukar panas berpengaruh terhadap peningkatan efektifitas penukar panas. Setiap peningkatan laju aliran udara sebesar 0.2 m 3/detik, maka efektifitas penukar panas naik sebesar 0.02 hingga 0.03. Namun, penambahan laju ini akan menurunkan suhu udara pengering yang dihasilkan.

Abstract

The increasing of food demand and maintaning the national food self supporting program have become the goverment concern. On the other side farm land convertion (especially in Java and Bali) into non-farm land has increased. So, as one of the solution, the goverment has opened many new farm lands outside Java. Most of them are tidal land. Tidal lands need an occurate contruction and water management system. The aim of the study is to determine the water management system for tidal irrigation land (on farming level) by controling water surface according to the cropping pattern. The location of study is Telang I tidal irrigation area, Kabupaten MusiBanyuasin, South Sumatera.

Abstract

Organic matter from manure are used not only for fertilizer but also can be used for preventing soil erosion and runoff. How to manage manure to soil for peanut and green pea CUltivation is especially important, because most farmers plant these crops. The objective of this research is to identify effect of: 1) organicmatter from chicken manure, cow manure and sheep manure on soil erosion and runoff in peanuts and green pea cultivations, 2) mulch from paddy, corn and leaf of banana on soil erosion and runoff. The design is divided into three experiments. First, field experiment for land preparation with treatment plowing with harrowing. Second, field experiment for peanuts and green pea crops with treatment chicken, cow and sheep manure. Third, laboratory experiment for mulching uses treatment with cover percentage of mulch from paddy, corn and leaf of banana. Land preparation using chicken manure decreased soil bulk density and increased soil porosity and aggregate stability index. Lower soil erosion and runoff is attained when treated with chicken manure. Productivity of peanuts and green pea are increased with the increase of manure. Using mulch of paddy, soil erosion and runoff are lower compared with using mulch of corn and leaf of banana.

Abstract

The purpose of this study was to learn technical performance and financial feasibility of a unit of mechanical post-harvest processing of pepper. The equipment used in such a process is thresher, peeler and dryer. The equipment was tested to learn its technical performances. It was found that the threshing efficiency of the thresher was 98% with a capacity of 269 kg fresh pepper spikes per hour and damaged berries of 5.3%. The peeling efficiency of the peeler was 98% with an optimum capacity (in term of fresh pepper spikes) of 224 kg per hour.The financial analysis showed that a unit of mechanical post-harvest processing of pepper with a capacity of 30,000 kg per year needs an investment of Rp. 82,060,000.00. This investment wi/l give an NPV of Rp. 141,605,144; net BIC of 2.37 and IRR value of 81.33%. An intensive and local specific study must be carried out to get appropriate conclusions of such an analysis.

Theoretically cdc,, of both gas N2 and 0 2 which have 5 degree offreedom are 1.4. The dzflerence was considered to be caused by thee xperimental condition, which were not suflciently adiabatic, as required by the method. However, the simplicity of the method and clarity of its theoretical approach is advantageous to be used by students of Advance Thermodynamic class as a practical exercise.

Abstract

Many,freezing methods, mechanicul as well as cryogenic, have been in wide application in food industries. Each method has its own advantage, but in regard with the food quality, freezing rule can be accomplished by the method is one of the tnost important factors. Nowadays, many researchers are conducting experiment in order to enhance thefi.eezing rate. This paper deals with the advantage of vacuum freezing method in enhancing the freezing rate and its applicability for liquidfood.Experinrent was carried out for distilled water, milk, and fruit juice using multi-purpose vacuum equipment. As easily predicted, minimum pressure of the freezing chamber determine temperature of the product. Vuriation on the fruit juice concentration shows that faster freezing rate canbe achieved if the product is more dilute. The experiment also showed that freezing rute obtained by vacuumj-eeziirg was signijkantly faster than contact plate freezing method.

Abstract

A model of how plant reacts to their micro climate is of great importance to control the physical micro climate around the plant and to other major input problems (such as rutinition intake). Artificial Neural Network (ANN) can be utilized to model a plant reaction to their microclimate in a more objective facshion by applying the ANN to measured data, and not from a pre-assumed model structure. This paper discusses a model of the plant response (the ratio of canopy area-stem diameter of baby cucumber) and the loss of nutrition solution as output and nutrition solution intake and microclimate (temperature, humidity, and irradiation) as input by using artificial neural network of dynamic response.
