SYNOPSIS

Water scarcity is a pressing issue nowadays. As it is clearly evident that there is a
daily increase in population, the need for water also rises. In order to meet the
needs of the community, it becomes necessary to redesign current treatment
plants or develop new treatment plants. Knowing the characteristics of raw water
is required for designing the water treatment procedure. To design the treatment
process of water we need to know the properties of raw water. The physical,
chemical, and biological properties of water have been determined. The method
of treatment of raw water is based on these properties. To ensure that water is
of a quality that is safe for consumption, common treatment techniques include
screening, filtering, aeration, sedimentation, and chlorination. Most water
treatment facilities have embraced this technique as the industry standard for
treating water. In our mini plant, Ultrafiltration and skimming are the processes
that we use as our new methods to treat freshwater. To simplify this,
ultrafiltration treatment works by using a pressure gradient to force water
through a semi-permeable membrane, leaving larger particles and minerals
trapped on the other side. Then, the skimming process removes oil from both
process water and Helps remove oil from the surface of oily water. Utilizing our
mini water treatment plant, we will convert fresh water to drinking water
according to the Malaysian water quality standard.

SYNOPSIS

Toxicity of leachate is determined from its characteristic that has many harmful
materials such as heavy metals. Some of the heavy metals found in leachate
include Chromium (Cr), Cadmium (Cd), Lead (Pb), Mercury (Hg), Nickel (Ni), Copper
(Cu), Zinc (Zn) and Iron (Fe). In overcoming this problem, many methods had been
investigated to remove the heavy metal in leachate efficiently such as chemical
precipitation, chemical oxidation and reduction, also membrane technologies and
evaporation. (Wang, 2011). The objective of this study is to investigate the
effectiveness of fruit peels as one of possible adsorption material in copper, iron
and zinc metal removal. Fruit peels that had been chosen is orange and banana
by making it into an activated carbon process the leachate was taken iat
sanitary landfill which is located at Sabak Bernam district. Based on the study
result, the percentage removal of orange peel with 4g dosage is the most
suitable to remove copper (99.06%) and zinc(97.53%) meanwhile orange dosage
2g (97.25%) is suitable in removing Iron in leachate . For banana peels, the
dosage of 1g is the most effective in removing iron, copper and zinc than 2g with
the percentage removal were 92.54%, 97.53% and 99.06%.

SYNOPSIS

Crops damage and surrounding damage of Polytechnic Sultan Idris Shah is a
grave concern of the students. Commercially available monkey repellents are
chemical based and disastrous to human health. An attempt has been made to
prepare three different 100% herbal product which is Chilli Powder Rice Ball, Chilli
and Pepper Spray, and Aloe Vera Spray. It is low-cost, effective and environment
friendly. Each repellent will be added with coconut oil, lemongrass oil and
lavender oil respectively. The efficacy of prepared repellents will be compared by
testing them with the monkeys around the polytechnic for a week. The
methodology used is by spraying them in any food and the parameters were
evaluated by levelling the meters where monkeys get away from the sprayed
food and each spray tested with ten monkeys. Based on the results obtained
from these parameters, the graph of efficiency is plotted by the data collected
from the presence of monkey day by day for one week. Also, the percentage
data of how many monkeys out of ten, get away from the sprayed food without
eating them was calculated.

USE OF BOKASHI TECHNIQUE TO PRODUCE ORGANIC
FERTILIZER FROM FOOD WASTE

SYNOPSIS

EM-Bokashi technology is a composting technique that uses useful bacteria to
decompose food waste into highly environmentally friendly crop products. These
bacteria will help destroy unnecessary bacteria in the soil during the planting
process. Among the bacteria found in EM-Bokashi are lactic acid bacteria,
phototropic bacteria and yeast. Bokashi in Japanese means “fermented organic
matter”. Bokashi ingredients are made by fermenting organic ingredients (bran,
coconut husk, fish flour, etc.) with EM.Bokashi (organic matter rich in microbial
biological resources) is the result of the fermentation of organic matter with an
effective stock of microorganisms. These can be used as organic fertilizers to
fertilize crops, enhance plant growth and production (Karimuna et al., 2016;
Zaman et al., 2016; Anhar et al. 2018), improve the soil better.

SYNOPSIS

Paper waste mortar is a product intended to cover defects on the face of brick
walls by reducing the sand material and adding waste material that is wasted
paper. Plastering mortar is mostly used in plastering building walls. The objective
of this product, one of which aims to reduce heat absorption when the weather is
hot. By practicing green technology by recycling waste materials and finding the
optimal ratio for the product. The ratio to produce the use of cement mortar is
1:1:6, paper waste mortar 1:1:5:1 for (10% paper waste) and the ratio 1:1:4:2 for
(20% paper waste). The size of the mold is 100mm × 100mm × 100mm. Among the
tests that have been carried out is the temperature testing. This product was
tested at the Sultan Idris Shah Polytechnic, concrete workshop. The concrete
blocks from this mixture of paper waste has been dried for 2 hours and the result
shown that the concrete absorbs less heat with a ratio 1:1:4:1 which is at a
temperature of 46 degrees. Hopefully this product can be used by contractors
and the general public.

SYNOPSIS

This paper investigates about agriculture irrigation which is one of the main
causes of economic decline. Electricity, water, and labor consumption are the
points that causing the problems. The construction of the IOT WATER IRRIGATION
SOLAR SYSTEM is intended to help the agricultural sector development without
having a negative impact on the environment. Based on the global evolution of
agriculture by product, the pollution that is caused from land extensive
exploration alone has caused many harms to environment. The National Water
Services Commission has targeted the consumption of 180 liters per day for each
population in 2020. In addition to that, the reduction of the labor force in Malaysia
in 2022 has recorded a loss of RM22 billion. Besides, it is absolute that the usage
of renewable energy such as solar power will save non-renewable energy. Studies
on soil moisture is suitable for determining the amount of water the soil needed
for agriculture. The production of IOT WATER IRRIGATION SOLAR SYSTEM was
designed to focus on moisture detectors, temperature and humidity sensor and
solar panel. Blynk Application also apply to this innovation use for recoding and
remote plant monitoring the from a far distance.
