Evaluation of energy uses for two types of holing method / Muhammad Ridhwan Suhaimi
Get PDFThe replanting operation of an oil palm as a whole need to meet the timeline provided. As holing is one of the processes in replanting operation, it is also important to complete it on time. Holing can be done either manually or mechanically. This study was conducted to evaluate the energy uses in two types of holing methods. Other than energy, the working performance over time and cost that involved in both methods was also evaluated. The data is taken at FGV Tembangau 7. The parameter taken was the food consumption of the labor, the amount of fuel used by the tractor, the area covered within a time, and the cost that involved the two methods of holing. The data then been analyzed using a formula to determine the energy usage. The result showed that the energy consumption by the labor which taken from the energy content of each food they eat is 6.388 MJ and the amount of fuel used by the tractor is 244.20 MJ. The labor can covered 0.72 hectare per day and the auger can covered 3.26 hectare in the same working hour. The cost of paying labor wages is RM 70 per day where the cost of using mechanically is RM 495 per day. It can be concluded that mechanical method is better than manual method. Many companies can use this case study to gain information and to make decision in choosing which method they could use in their plantation

Malay proverb e-learning system with gamification for children / Muhammad Ridhwan Mohamad Munir
Get PDFThis project focusses on the development of the Malay Proverb E-Learning system that is integrated with gamification. The system was designed and developed using the web-based applications such as the MYSQL as the database, HTML,JAVASCRIPT, CSS, and PHP as the programming language and Apache web server, with multimedia tools to facilitate e-learning in graphical representations. Gamification is a new concept. It is still not been taken seriously in academic studies and research. It has been defined as the use of gaming elements and mechanics in the non-gaming system. This paper discusses more closely the strategies appropriate for education throughout e-learning and introduces a template that defines the development of the educational gamification system. The implementation of gamification in e-learning was rendered in line with the structure suggested in this paper. The development of the system involves five phases of methodology which are Project Planning, Project Requirements, Project Designing, Project Development, and Project Documentation. At the end of the system development, series of usability and user acceptance tests were conducted to evaluate whether the E-Peribahasa system is helpful to improve children’s knowledge about Malay Proverb. As a result, the system is able achieved all the objective of this project and creating an enjoyable learning environment for the children to learn Malay proverb

Get PDFSelective removal and recovery of gold and copper ions from aqueous solution by PKFAD- impregnated chitosan / Muhammad Ridhwan Abdul Rahim
Get PDFChitosan is one of the developing biosorbent that becomes main interest among the researchers since it can be used to recover various types of heavy metals in the aqueous solution. A lot of physical and chemical modifications had been done toward the chitosan in order to increase its effectiveness for heavy metals recovery. In this research, the recovery of gold and copper ions from the aqueous solution has been investigated by using PKFAD-impregnated chitosan as biosorbent, since there is no research had been conducted for this new biosorbent. It is necessary to be conducted since the conventional method like solvent extraction bring more negative impact to the environment. The objectives of this research are to investigate the effects of different parameters on the selective sorption of gold and copper from aqueous solution by PKFAD-impregnated chitosan and to propose suitable desorbing agents for gold and copper recovery from PKFAD-impregnated chitosan by literature review. To synthesis the PKFAD-Chitosan beads, the raw chitosan needs to be dissolved with 3% acetic acid before mixed with the PKFAD. The formation of the beads can be done by dropping the mixture solution wisely into the methanol/ammonia solution. The investigated parameters for gold and copper ions recovery are pH of the aqueous solution, initial ratio concentration of aqueous solution and biosorbent dosage. Based on the result obtained, the highest percentage adsorption of Au(III) and Cu(II) can be achieved at pH = 3.24 (96.9%) and pH = 5.53 (71.1%) respectively. When the pH is increasing, the selectivity of Au(III) over Cu(II) reduced from 28.772 to 0.328. For the initial ratio concentration, it can be observed that the adsorption capacity of gold increasing from 6.66 mg/g to 30.719 mg/g with the initial ratio Au(m):Cu(FT) from 1:1 to 5:1. However, the selectivity of Au(III)/Cu(n) is much lower compared to Cu(n)/Au(III) even though the concentration of Au(III) is five times higher than Cu(II). For the adsorbent dosage, the adsorption capacity were decreased for both Au(III) (13.29 mg/g to 3.94 mg/g) and Cu(II) (12.59 mg/g to 2.53 mg/g). The selectivity of gold over copper start to surpass at the adsorbent dosage 0.16 g. For the desorption process, the combination of eluents, thiourea and HCl is highly potential to recover Au(III) from PKFAD-Chitosan beads. Meanwhile, the recovery of copper can be done by using HCl, HNO3 and EDTA that act as the eluents
Smart water tank for sustainable irrigation / Mohamad Nadzrin Norisam, Muhammad Ridhwan Afiq Sunsuki and Nur ‘Amira Hamid
Get PDFThe plant's development, germination, and productivity are all influenced by water. Water availability for irrigation has become increasingly vital as agricultural production has increased to fulfil global food demand. Previously, conventional agriculture was the most common method among farmers due to its great productivity in generating the product. However, over the last decade, traditional farming practices have been replaced with more sustainable ones. This is because, despite their high production, traditional practices can harm the environment and generate social disturbance. In terms of generating high-quality products without polluting the environment, sustainable agriculture is now playing a key role in the agricultural industry. One of the sustainable agriculture practices is to use rainfall as a source of water for irrigating crops. It's because it recycles rainwater and reuses it for agricultural purposes. At the same time, it has the potential to shift the use of clean water to more expensive treated water. One of the choices and productive strategies for storing rainwater for irrigating the crop is to use a rainwater collecting tank as a storage tan

Serupa tapi berbeza: kajian kes komuniti Bawean Kampung Sungai Tiram, Johor Malaysia
No full textMelayu sebagai suatu kategori sosial di Malaysia bukanlah bersifat homogen kerana terdapat beberapa sub etnik yang terkandung di dalamnya. Salah satunya ialah orang Bawean yang telah merantau ke Tanah Melayu sejak sebelum kemerdekaan dicapai meskipun kurang dikenali berbanding etnik Jawa, Bugis dan Banjar. Sifat merantau di kalangan lelaki Bawean adalah sangat kuat sehingga digelarkan wira apabila pulang ke Pulau Bawean dengan hasil seperti wang dan emas. Kajian ini meneliti latar belakang etnik dan identiti orang Bawean di Malaysia yang berhadapan dengan konflik pembinaan negara-bangsa Malaysia. Data primer diperolehi daripada analisis kandungan dan temubual mendalam di lapangan dengan 50 ahli komuniti keturunan Bawean di Kampung Sungai Tiram, sebuah ladang kelapa sawit yang menjadi tempat berkumpul dan kunjung mengunjung orang-orang Bawean yang tinggal di sekitar Ulu Tiram dan dalam Negeri Johor. Hasil kajian mendapati lima elemen identiti dalam kalangan masyarakat Bawean, iaitu agama Islam, amalan merantau, bahasa, amalan gotong royong dan ilmu perubatan tradisional. Meskipun agama Islam telah mempermudah orang Bawean untuk beradaptasi dengan masyarakat lokal di Malaysia yang seolah-olah menunjukkan keserupaan budaya mereka dengan Melayu tempatan namun budaya etnik Bawean sebenarnya boleh dikatakan berbeza. Hal ini dapat dilihat dari hakikat bahawa sehingga ke hari ini masih berterusan wujud perkampungan eksklusif orang Bawean di Malaysia seperti di Johor
