Characteristics of Groundwater from Fractured Hardrocks in West Coast of Peninsular Malaysia
The thesis examines on the chemical characteristics of groundwater
found in granitic and metasedimentary rocks of the West Coast of Peninsular
Malaysia. A total of 133 tubewells having diameter 20 cm were studied. The
wells were drilled to a depth between 100 to 200 m. The top 20 to 40 m of
the wells were cased, fol lowed by 60 to 80 m Of slotted casing. The
remaining depth of the wells was left open. The present study shows that the
quality is mostly fresh with average pH and conductivity around 6.5 and 200
µS/cm respectively. The total dissolved solids range between less than 100
mg/l to more than 200 mg/l with average of a bout 120 mg/l. The
groundwater is classified as soft to hard water because the hardness ranges
between 12 mg/l to 180 mg/l. the groundwater facies was found to be
Calcium Bicarbonate, Magnesium Bicarbonate and Sodium B icarbonate water. Calcium and Magnesium in metasedimentary water have average of
about 17 mg/l and 21 mg/l, respectively. For granite, the average of Ca and
Mg is 8.75 mg/l and 2.85 mg/l. The amount of iron content can be as high as
15 mg/l with average of 1.5 mg/l. More than 50% of the groundwater
samples exceeds the limit of iron for drinking water of 0.3 mg/l. Fluoride
concentration is generally low with average Of 1.0 mg/l. However,
groundwater from granite can reach the level of Fluoride to 11.5 mg/l. the
groundwater is classified as medium to low salinity hazard and low in
sodium; therefore it is suitable for irrigation.
The thesis also examined the production capability of the hardrock
aquifers. The top 20 m was mainly in the residual soil and weathered part of
the rock. Fresh hardrocks were normally encountered at depth more than 40
m. the static water level or water table in the study area were found to be less
than 20 m deep. Four of the wells were outflowing automatically above the
well head casings, which was constructed about 0.5 m above ground. High
discharge rates up to 800 m³/well/day were encountered from wells that
penetrated major fracture zones. Average discharge rate for metasedimentary
and granite aquifers were 400 m³/well/day and 300 m³/well/day, respectively
and the drawdown is generally less than 50 m from the ground level. The
wells were drilled for various purposes such as for rubber, latex, textiles and
mineral water bottling factories, poultry and agricultural activities and
domestic water supply
Recent research in cooperative path planning algorithms for multi-agent using mixed- integer linear programming
Path planning is one of the issues to be handled in the development of autonomous systems. For a group of agents, cooperative path planning is crucial to ensure that a given mission is accomplished in the shortest time possible with optimal solution. Optimal means that the resulting path has minimal length hence the total consumed energy by the agents is the least. Cooperative path planning fuses information from all agents to plan an optimal path. There are a number of cooperative path planning methods available in the literature for multi-agent including Cell Decomposition, Roadmap and Potential Field to name but three. This paper will review and compare the performances of those existing methods that can find solution without graph search algorithm such as Mixed-Integer Linear Programming (MILP) techniques which exactly solves the problem and then propose four alternative MILP formulations which are computationally less intensive and suited for real-time purposes, but yield a theoretically guaranteed suboptimal solution

Measuring the Effect of Organizational Culture on Organizational Performance : A Case Study at B.M.Nagano Industries Sdn. Bhd. (Pasir Gudang, Johor)
The purpose of this case study was to measure the effect of organizational culture on organizational performance. Demographic characteristics such as age, gender, place of
origin, role, race, length of service and education qualification were also measured to examine the relation of organizational culture and organizational performance.
Questionnaires contain of three sections which are demographic characteristics, organizational culture and organizational performance were used to collect data. In the demographic section, data gathered include age, gender, place of origin, marital status, education qualification, position, length of service and race. Denison Organizational Culture Questionnaire was used to measure organizational culture. Meanwhile for third
section, organizational performance developed by Watskin and Marsick were used for the purpose of this study.
The data were analyzed using SPSS 11.5. Five main hypotheses were tested using Oneway ANOVA and Pearson’s Correlation Coeeficient. From the result it was found that
there are no positive relationship between organizational culture and organizational performance
Factors Affecting Rural Youth Interest in Agriculture in Sindangkasih Ciamis District
A study on farmer regeneration has been carried out in Sindangkasih Subdistrict, Ciamis in April - July 2019 with the aim of the study: (1) to describe the extent of youth interest in agriculture, (2) find factors that influence youth interest, and (3) formulate an improvement strategy youth interest. This quantitative descriptive study involved 79 young people as respondents from 3,158 people. Data collection using a questionnaire containing closed questions in accordance with the variables and research indicators that have been tested for validity and reliability. Descriptive analysis is carried out to provide an overview of youth interests, while to identify influential factors, multiple linear regression analysis is performed. The results showed (1) youth's interest in agriculture is included in the sufficient category, (2) youth's interest is influenced by external factors (extension activities, availability of resources, government support) and motivational factors (rewards, achievements, demands of life) with the Y model = - (0.051) + (0.457) X2 + (0.419) X3, and (3) strategies for increasing interest begin with facilitating youth in non-formal education (training / courses), and involving youth in agricultural program
Comportamiento de compra impulsiva en Instagram entre las generaciones Y y Z en Indonesia
Instagram has become a major platform for online shopping, especially among the younger generation. Understanding the factors thatinfluence impulsive buying on social media has become increasingly relevant for marketers. This study examines the influence of Instagram usageintensity, extroversion, and positive shopping emotions on impulsive buying behavior, with a particular focus on generational differences betweenGeneration Y and Generation Z. Data were collected from 442 respondents through a structured questionnaire and analyzed using SmartPLS 3.3.2to test six hypotheses. Validity and reliability were assessed using Cronbach’s alpha, composite reliability, and average variance extraction (AVE).Findings reveal that for Generation Z, frequent Instagram use and positive emotions significantly drive impulsive purchases. In contrast, forGeneration Y, extroverted personality traits have a stronger influence on buying decisions. These results highlight distinct psychological patternsacross generations in online shopping behavior. The study provides practical insights for marketers seeking to tailor their strategies to meet generationalpreferences. By identifying different behavioral drivers, it contributes to the growing literature on digital consumer behavior and guidesbrands operating in social media environments.Instagram se ha convertido en una importante plataforma para las compras en línea, especialmente entre la generación más joven.Comprender los factores que influyen en las compras impulsivas en las redes sociales resulta cada vez más importante para los profesionales del marketing.
