Quality evaluation of microwave dried guava
Universiti Malaysia Perlis (UniMAP)
This study is carried out to evaluate the effect of different microwave powers on the quality of microwave-dried guava in term of vitamin C degradation. The study was conducted by determining the initial moisture content of fresh guava followed by
drying the guava using microwave oven until it reached the desired final moisture content. The effect of microwave heating on the vitamin C content of microwave-dried guava using three microwave power levels of 300 W, 450 W and 600 W was
determined by using High Performance Liquid Chromatography (HPLC). The drying characteristics established during microwave drying which included moisture content
and drying rate were observed.

Banana is one of the food sources which contain a lot of vitamins that are beneficial to the human body. It is a popular tropical fruit that has high market value all over the world. Currently, banana is sorted manually by the fruit sellers or suppliers from color inspection of the peel color. This process is relatively slow and time-consuming, higher cost and labor demanding. The major purpose of this study is to establish the maturity index level of local banana variety, Pisang Berangan based on the extracted color features at 3 different maturity stages by using vision machine system. In this study, 30 banana samples were used in image acquisition. The images were grabbed in 2 different views: top and side views daily using a CCD camera set up in a black box. All of the acquired images were processed using several image processing procedure to enhance the image quality and
separate sample image with the background image. Image processing procedure such as IMAQ Threshold was carried out in the LabVIEW programming software. Color features data such as RGB, L*a*b* and HSV were extracted based on the acquired image. All of the extracted data were analyzed using Qualitative Data Analysis (QDA). From the analysis, a maturity index level chart of Pisang Berangan is produced to assist the sellers and suppliers in classifying the banana according to the corresponding ripening stages for a better postharvest management procedure.

Comparison of different media filtration for rainwater harvesting system
Nur Amelia, Ariff
In Malaysia, the rapid growth of urbanization, population and industrial has caused the water demand getting higher over a year including Perlis State. So, this study was conducted to treat the rainwater as a water supply by rooftop harvesting technique for non-potable use domestic purposes. Several tests hads been conducted to determine the quality of rainwater after and filtration process which is pH, Total Suspended Solid (TSS), Biochemical Oxygen Demand (BOD), Ammonia nitrogen (NH3N) and Dissolved Oxygen (DO). The rainwater was treated into two type of filtration system which involved rice husk and rice husk ash as filter media. Both of these mediums were compared to ensure the quality of the rooftop rainwater harvesting is improved. The quality of rainwater was tested by using 3 sample from rooftop rainwater, rice husk and rice husk ash filtration. Besides, for the designing of filtration system, each treatment is divided into three layer which from bottom is gravel, sand and treatment (rice husk or rice husk ash). The result from experiment shown that, the pH of rainwater change from 4.16 to 8.33 when using rice husk ash media filter whereas in Ammonia Nitrogen test, rice husk ash able to lower down the Ammonia Nitrogen from 0.26 mg/l to 0.17 mg/l whereas for rice husk is 0.21 mg/l. In the other hand, for Biochemical Oxygen Demand, rice husk reduces the value of BOD from 13.33 mg/l to 9.54 mg/l and the DO is 1.34 mg/l compare to rice husk ash is 1.45 mg/l. In the conclusion, the best system was system that use rice husk and rice husk ash.

Soil Nitrogen, Phosphorus and Potassium (NPK) mapping using ArcGIS for Harumanis under greenhouse at Sg.Chuchuh, Perlis
Ahmad Zulfadzli, Mohamed Yusoff
Final Year Project (FYP) was carried out to determine the Nitrogen, Phosphorus and Potassium (NPK) for Harumanis under greenhouse at JPB Asia Pacific, Sg Chuchuh Perlis using ArcGIS. The study starts by collecting soil sample in the Greenhouse 03 that planted with Harumanis. This study was focusing on content of NPK because nutrients were important in order to maintain plants in an optimum condition until they were harvested. This study also carried out to generate a simple map using ArcGIS to provide NPK distribution and give information to researcher which is related to the soil research in order to get data of NPK. Through this study have been conducted, the contents of NPK can be determined by ex-situ (experiment in laboratory using standard lab procedure). From the data collected, most of nitrogen contents were not in the optimum condition. While, the phosphorus and potassium contents was adequate due the value of results recorded that >50% plants have more than optimum value both for phosphorus and potassium.
