Oil palm management by using aerial photography and ArcGIS software / Nabilah Ismail

Monitoring process for oil palm needed more precise innovation, cheap, fast and accurate technology. Before the existence of new technology, farmers used manual or traditional technique to manage their plantation area that is time and labour consuming. Remote sensing is one of the most reliable measurements tools for accurate monitoring and managing over large area. The purpose of this study is to count the oil palm tree in the plantation, to check the spacing distance between the oil palm trees and to monitor the status and obstacle in the oil palm plantation area. This study was conducted at Share Farm UiTM Jasin Melaka. Drone and Global Positioning System (GPS) were used to capture the oil palm area and to collect the coordinate of the oil palm tree. ArcGIS software 10.3 has been used in this procedure. The tree and the distance of the oil palm were measured. Based on the results, it shows that the oil palm tree area is unorganized because of some obstacles. The obstacles that has been observed is clogging water, which it resulted from the old water reservoir used to accumulate water for oil palm tree activity usage. A part from that, fallen trees and old tree is also considered as the barrier in the oil palm area. In conclusion, ArcGIS software facilitates farmers to monitor and manage their plantation field. Thus, Precision Agriculture can be recommended as a better alternative than the existing traditional method

Sifat fizikal dan keupayaan mekanikal konkrit campuran abu kulit kupang (perna viridis) sebagai bahan tambah

Matlamat SDGs selari dengan inisiatif RMK-11 iaitu pengaplikasian teknologi hijau di dalam pembinaan infrastruktur yang mampan, berkonsepkan lestari dan pemuliharaan alam sekitar. Kajian ini memfokuskan kulit kupang yakni limpahan sisa akuakultur yang tidak diurus dengan tepat untuk dijadikan bahan tambah di dalam campuran konkrit bagi meningkatkan nilai kulit kupang dan keupayaan konkrit campuran bagi memacu infrastruktur yang lestari. Kupang yang telah di proses menjadi abu di tambah di dalam konkrit sebanyak 1%, 2%, 3% dan 4% dan melalui proses pengawetan air biasa selama 7, 28 dan 60 hari dengan sasaran gred 30MPa. Penyelidikan ini memfokuskan beberapa ujian pencirian bahan iaitu sifat-sifat fizikal (graviti tentu, masa pengerasan dan serakan saiz partikel), dan kimia (X-Ray Powder Diffraction ), morfologi partikel (Scanning Electron Microscope), keupayaan konkrit (kebolehkerjaan, kekuatan mampatan, kekuatan tegangan dan serapan kapilari air dan analisis statistik (korelasi dan signifikan). Dapatan sifat-sifat fizikal abu kulit kupang mendapati kulit kupang lebih halus (saiz diameter purata 8.284μm) dan ringan (nilai graviti tentu 2.52) berbanding simen Portland biasa memberi kelebihan di dalam masa pengerasan, kebolehkerjaan dan serapan kapilari. Bagi nilai keupayaan konkrit mampatan , tegangan dan serapan kapilari air konkrit campuran 2% abu kulit kupang adalah lebih baik berbanding konkrit campuran yang lain. Selain itu, tempoh pengawetan 7, 28 dan didapati tiada perbezaan yang signifikan (p > 0.025) bagi konkrit campuran 2%. Berdasarkan dapatan kajian abu kulit kupang mempunyai potensi sebagai bahan tambah yang menghasilkan konkrit berkekuatan awal dan berkeupayaan tinggi. Penyelidikan ini menambah pengetahuan bahan pembinaan , meningkatkan nilai kulit kupang serta memastikan infrastruktur berkonsepkan kehidupan lestari dan pemeliharaan alam sekitar di dalam matlamat SDGs dan dasar RMK-11 dicapai

Diary Web – Based Application

This document is a fully completed stage report for a project titled “Diary Web – Based Application” that relating to how aspects of apply the diary in life and an electronic application of audio voice recorder that can be combined to create a fully autonomous voice recording for diary machine. The existing application of diary application that applicable is a web – based system where it will automatically generated from user ideas, histories or activities that need to be saved. It consists of location, time and date for the information that being recorded but it not useful when retrieved as references or playback the information. In this project had do a researched, designed and ultimately implemented using a combination of web based which is XAMPP Software that consist of PHP language, Apache Application and also using Database system application which is MySQL for record purposes in the application system development.

Study of SAWDUST: Methyl Methacrylate Polymer Composite Properties

In recent years, there are concerns for the production of sawdust polymer composites as there is huge amount of sawdust can be found easily and they can easily incorporated with polymers to improve the properties. However, problem arises when the properties of sawdust are influenced by many other factors such as amount of the polymer loading and size of sawdust. Furthermore, the increase demand in using sawdust composites results in a need for a better understanding of the effect of polymer loading and particle size on the characteristics of sawdust composites. So, from this study we will identify the influence of the chemically treated sawdust with polymethyl methacrylate at various particle sizes of sawdust and polymer loading. Apart of that, the research also would like to find out the mechanical and morphological properties which include moisture content, density, flexural, tensile and thickness swelling. These are vital, because we want the composite structure to be durable and to have better properties. In this work, composite materials were prepared from polymethyl methacrylate with four different size of sawdust (1.99mm ≤ x ≤ 1.18mm, 1.17mm ≤ x ≤ 0.425mm, 0.424mm ≤ x ≤ 0.212 mm and 0.211mm ≤ x ≤ 0.063mm) with three different ratio of fillers (10%, 25% and 75%). The molding method is used to prepare the specimens of sawdust composite. The mechanical properties studied include tensile and flexural strength where the dimensional stability studied includes water absorption, thickness swelling and density. The results show that the composite material had lower water absorption compared with raw sawdust. Also for the effect of filler loadings on the composite, increases amount of filler loading gives better mechanical properties to the composite but the percentage of water absorption and thickness swelling are also increases. Lastly for the effect of particle sizes on the composite, large particle size are found to give better mechanical properties, however the percentage of water absorption and thickness swelling will also increase with an increase in particle size

A preliminary study of phytochemical contents in commercial Malaysian black tea extract using quantitative and qualitative tests

Black tea (Camellia sinensis) is a flavoured, functional, and therapeutic non-alcoholic drink that is consumed by two-thirds of the world’s population. In this study, the bioactive compounds in black tea leaves were extracted using two different solvents which are methanol and acetone before being further characterized with FTIR to identify the functional groups. The presence of active compounds such as gallic tannin, catecholin tannin, phenol and flavonoid compounds were further tested with qualitative and quantitative methods. Based on FTIR results, the best solvent to extract tea leaves was acetone. The frequency obtained for phenolic –OH stretch was 3390.5 cm-1, while alkane –CH3 stretch appeared at 2921.4 cm-1 and 2850.7 cm-1. The UV-Vis spectrum was obtained and the λ max from the spectrum is 270 nm. Qualitative analysis involving ferric chloride and lead acetate test showed positive results for the presence of gallic tannin, catecholin, flavonoid and phenols in the tea leaves extract. From the quantitative test, the total phenolic content was 0.9217 mg gallic acid equivalent (GAE)/L while the concentration of flavonoid content was 0.7792 mg quercetin/L and total tannin content 0.13 g/g respectively
