Abstract
The polyculture system provides great benefits in cultivation, including increasing the productivity of land aquaculture, utilizing leftover feed, and improve water quality. The aim of this study was to analyze the competition index and growth performance of tilapia (Oreochromis niloticus), depik (Rasbora tawarensis), lemeduk/tengadak (Barbonymus schwanenfeldii) and peres/nilem (Osteochilus kappenii) in the polyculture system. This research was conducted at Fish Seed Center (BBI) Lukup Badak, Pegasing District, Central Aceh Regency on May – June 2020. This study used a completely randomized design consisting of 4 treatments and 3 replications, namely treatment A control (tilapia 150 of fish in monoculture system), treatment B (tilapia: 112 fish and lemeduk: 38 fish), treatment C (tilapia: 112 fish, depik: 38 fish), and treatment D (tilapia: 112 fish, peres: 38 fish). The experimental fish were reared in a happa container with a cage system of size 0.5x0.5x1m. The results showed that tilapia reared in the polyculture system had a significant effect (P <0.05) on growth performance compared to monoculture system (treatment A). The competition index shows a negative value between treatments. The research indicated that the best experimental was treatment B (tilapia: 112 fish and lemeduk: 38 fish) and treatment D (tilapia: 112 fish, peres: 38 fish) can increase growth performance and biomass production in polyculture system. In conclusion that the application of the polyculture system of tilapia was able to increase the value of growth performance and there was no competition between experimental fish.

AbstractPlankton is the primary food sources for many fish larvae as well as other organisms during their early stage of development. Zooplankton such as copepods play a major role in freshwater and marine environment as live food that offer great variety of sizes, species and nutritional value to the larvae. The aim of this study is to increase the nutritional value of copepod and its effect onPenaeus monodonpost-larvae growth performance. The experiment was carried out 30 days and comprised with four different treatments of diets. The diets fed to copepod consisted of algal diet which isTetraselmissp. that acted as a control followed by three types of vegetable-based diet which is carrot, water spinach, and lettuce. The efficiency of the copepods enriched was further evaluate on its growth, survival and proximate composition. The outcome of the study showed that highest specific growth rate (SGR) inP.monodonpost-larvae was obtained when fed with copepods enriched water spinach (11.28±0.38%) and the highest survival rate ofP.monodonwas obtained when being fed with copepods enrichedTetraselmissp. (91.67±0.29%). Proximate analysis composition for enriched copepods andP.monodonfed with enriched copepods showed the water spinach produce highest protein and lipid content compared to other enrichment. The current result showed that vegetable based are able to replace the microalgae, hence it also can gave an advantages to the economy in aquaculture and higher yields.

Abstract
Feed is one of the important components in fish farming as a source of material and energy, feed is also the largest component (50-70%) which causes an increase in production costs. Therefore, to reduce feed production costs is to mix inexpensive and easily accessible natural feed with a high enough protein content. During the harvest season the avocado is abundant and avocado seeds are disposed of as waste. This study aims to determine the effect of a combination of avocado Perseaa mericana M. and pumpkin Cucurbita moschata D seed on the growth and feed efficiency of Osphronemus gouramy Lac. The design used non-factorial Completely Randomed Design consisting of 4 treatments and 6 replications: P0 (control feed), P1 (40 grams of avocado seed feed + 40 grams of pumpkin seeds + 20 grams of mixed ingredients), P2 (20 grams of avocado seed feed + pumpkin seeds 60 grams + 20 grams of mixed ingredients) and P3 (60 grams of avocado seed feed + 20 grams of pumpkin seeds + 20 grams of mixed ingredients). Data analysis used Analysis of variance and Duncan’s test using SAS 9.3.1 software. The results showed that giving a combination of avocado seeds and pumpkin seeds can increase the growth of gouramy. The highly effective growth was found in P2 feed of 11.86 grams with a growth rate of 2.69% / day, while low growth occurred in the P3 treatment of 9.46 grams with a growth rate of 2.11% per day. The proximate test of the test feed showed that the highest protein was found in P2 feed, namely 25.01%. The best feed efficiency was found in P2 feed which had 6.91% crude fiber, and the highest protein content in P2 was 18.36%. It concluded that there was an effect of a combination of avocado and pumpkin seed feed on the growth and feed efficiency of Gouramy.

Abstract
In this paper, demonstration of how an individual cow can be tracked and identified in a herd of cows using an enhanced particle filter is presented. In a typical agricultural setup, it is not uncommon to witness cases of cow swapping and rustling. In the past, different methods were recorded in literatures for the monitoring of herds. However, advancement in technology has rendered those methods less effective, resulting to demand for continual improvement on the state-of-the-art methods for tracking individual cows. To achieve this, we employed off-the-shelf networks for end-to-end individual cow identification in up-to-down motionless imagery acquired from stationary camera. The dynamic trajectory of the herd was captured by a camera installed on a pole near a passageway through which the cows passed almost every day and the video processing system was employed for the processing of the herd’s trajectory. Report was made on the model initialisation, mean shift algorithm, particle-Kalman filter, and the target model is updated in order to overcome the change in the target object appearance over time. To our utmost knowledge, this work is the first to apply combination of mean-shift based tracker and particle-Kalman filter as enhanced particle filter to real-time cow detection and identification to curtail occlusion and non-linear tracking problem.

Abstract
In Malaysia and various Asian countries, use of motorcycle is growing in numbers, and the motorcycle is the dominating transport mode. In fact, the number of motorcycles per thousand people averaged over several major Asian cities is significantly higher than the average of the rest of the world. With growing use of motorcycle, blind spots have become one of major cause to road injuries and fatalities of motorcyclists in Malaysia. In this work, a visual-based detector is proposed to reduce the risk of blind spots in causing road injuries to motorcyclists. The objective of this detector is to provide alerts to the drivers of cars and other vehicles when there are motorcyclists in proximity to the vehicles especially around blind spot areas. In developing this solution, a variant of deep network called You Only Look Once (YOLO) is chosen as visual-based detector. This YOLO deep network is trained and tested using the 5811 collected images of motorcyclists. A benchmark with regards to its accuracy and speed is conducted by comparing this visual detector against several methods such as Aggregate Channel Features (ACF) and Faster Region Convolutional Neural Network (FRCNN). Results showed that YOLO detector is the most superior detector since it has the best average precision out of all detectors, and its inference time at 22.55 ms (44 fps) is able to provide real-time implementation. Besides, YOLO inference on machines without GPU still manage to achieve a commanding performance, which is on average, at 17 fps.

Published: March 2021

Abstract
Stress has become one of the major mental health problems in Malaysia. Most Malaysians underestimate and neglect this critical issue, not knowing what the consequences might be due to the lack of knowledge on stress analysis. Many researchers are trying to identify the causes and ways to overcome stress. With the help of advancing electronic systems engineering, primed heart rate biomarker has been earmarked as the tool to analyse stress. However, the relationship between heart rate variability approach and the quantification of stress is still an open research challenge. Therefore, the goal of this study is to explore the role of heart rate variability (HRV) and psychometric scale on stress and resilience analysis among university students and the effectiveness of interventions and Heart Rate Variability devices on improving resilience. 30 students, 15 males and 15 females aged 23 to 24 years old were picked as the subjects for this experiment according to their stress and resilience scores obtained from two questionnaires, Brief Resilience Scale (BRS) and Depression Anxiety Stress Scale-21 (DASS21). Their heart rate variability was measured using HeartMath EmWave device to observe the changes of their heart rhythm when a stimulus and an intervention is given. The data acquired from HeartMath EmWave were analyzed using Kubios HRV software, where it provides more in-depth analysis regarding the subjects’ heart rate during the experiment. According to the results, most of the subjects’ heart rate becomes incoherent during the stimulus phase. However, their heart rate changes into a coherence state due to the effectiveness of slow breathing techniques as an intervention. It helps the subjects to become calmer and synchronize their autonomic nervous system (ANS) with their brain and heart. Therefore, choosing the right intervention is vital to get a coherent heart rate, thus train how our body responds to stressors. The results also provide fruitful insight relating to how a human reacts when they are facing something difficult in their lives and indicates that heart rate variability biofeedback is important to achieve human wellness and validate the quantification of resilience and stress. This study concludes that the heart rate variability device and measurement are effective and have a vital impact to create stress awareness.

Abstract
Graphic health warning label is an advertisement approach to promote greater public understanding on negative health consequences of smoking. A large volume of data has accumulated on the issue of cigarette smoking health warning labels recently, as the number of smokers are yet still growing, reaching 1.1 billion people who smoked every day. This rising in number of smokers were predicted to significantly impact the number of cases to increase directly proportional related to critical disease such as heart disease and stroke. Therefore, a comprehensive strategy needs for efficient tobacco control, an informative communication campaign and strategy such as pictorial disease warning label that have been conducted since 2009. However, justification of the current evidence on relative warning labels effectiveness are still questionable. This study therefore targeted to investigate the abilities of warning labels in informing the negative consequences related with cigarette smoking, through the cutting technology of eye tracking. 30 students had completed this experiment including both smokers and non-smokers in order to directly assess on how the eye movements react towards the graphic stimuli using eye tracking method. Tobii TX300 eye tracker were used for data collection, filtration and analysis, as the device were more detailed and proven to be less bias compared to usual verbal report. Which helping in interpreting human behaviour in obtaining subjects attention. The collected data sets were further analysed using one-way analysis of variance (ANOVA) technique. With the small difference in results of significant value at 2.15 x 10−19 for eye movement event occur between two categories of subjects, shows that their eye activities towards pictorial warning labels are significantly same, as both categories of subjects focused on same part of the image. Pictorial warning labels were believed to be inefficient to continue as a strategy of tobacco control nowadays as the result showed that critical disease images were ineffective in informing the negative consequences related with smoking cessation. The findings indicate that the strategies could be improve besides using pictorial warning labels that have been conducted over a decade.

Published: March 2021

Abstract
We demonstrate a simple optical based humidity sensor using a micro cavity. The micro cavity consists of single mode fiber (SMF-28e, Corning) and a reflective mirror coated with zinc oxide (ZnO) which is embedded in polyvinyl alcohol (PVA). A wideband amplified spontaneous emission (ASE) source, ranging from 1530-1610 nm was injected into the micro cavity. The water molecules from the surface of the ZnO-PVA changed the refractive index of the micro cavity which subsequently modified the phase of ASE light that was reflected from the coated mirror. The change of phase in the reflected light from the coated mirror was monitored with optical spectrum analyzer (OSA). The performance of our optical humidity sensor for non-coated mirror and ZnO-PVA coated mirror was recorded at 0.03 nm/RH% and 0.074 nm/RH%, respectively. This shows that optical humidity sensor with ZnO-PVA coated mirror is more sensitive to humidity changes.
