Published: March 2021

Abstract
Different techniques of software testing are adopted to deal with bugs found in the highly complicated multifunctional software. However, those techniques have difficulty detecting bugs effectively because most of the bugs are triggered by interaction failures between the input parameters and values in the system. Thus, combinatorial t-way testing strategies have come into existence to produce quality minimized test cases, as well as those test cases can cover all the necessary interactions of parameters once at the least. Besides, as t-way testing is considered as an NP-hard problem, new strategies are always welcomed in this research area in pursuit of the optimum test suite. The main point of this paper is to propose the concept of a type of artificial intelligence (AI) algorithm called gravitational search algorithm (GSA) for t-way interaction testing. GSA is a stochastic optimization algorithm inspired by Newton’s law of gravity and motion and has been widely applied to figure out optimal solutions to real-world issues.

Published: March 2021

Abstract
Radio Frequency (RF) based indoor is challenging due to the multipath effect in indoor signal propagation such as reflection, absorption, diffraction due to obstacles, interference and moving objects within the environments. The multipath effect phenomenon will be worsened if Received Signal Strength (RSS) is used as the localization measurement parameter. The advancement of Artificial Intelligence (AI) may hold the key for the improvement of RSS based localization. The Artificial Neural Network (ANN) in AI outperforms the traditional algorithms in indoor localization due to its capability to learn the unique features given in the training datasets. This paper discusses indoor fingerprinting localization with different architectures of ANN network to localize object of interest with the given indoor environment. The size of the experimental testbed is 14m x 8m and the testbed consists of four identical receivers that receive the signal from an active transmitter. All the tested ANN architectures have RSS as inputs and the Cartesian coordinates as outputs with different hidden layers and hidden nodes. The relationship between hidden nodes and layers in ANN and the regression losses is studied in this paper. The RSS-based fingerprinting with ANN in this paper is considered as a multi-output regression problem. The result shows that the ANN architecture with four layers with a total number of 800 hidden nodes has achieved an average of 6.01098 regression losses and a mean Euclidean Distance error of 2.54m.

Abstract
Blob detection and localization is a common process used in the machine vision. Current existing blob detection method is using 2-dimensional kernel matrix which is higher in time consumption and also memory space. This study has proposed a dedicated digital architecture consist of two modules to detect binary image blob using only 1 -dimensional image pixel. First module is used to detect connected pixel in a row of pixel, and second module is used to perform windowing to justify blob location. This study has been successfully implemented and tested on Altera DE2 FPGA board. The proposed architecture only takes 24 clock cycles to deliver blob location and related features. The tested architecture only utilizes 1597 logic element, or 4.81% of the FPGA total resources.
Extreme rainfall in New Zealand and its association with Atmospheric Rivers

Published: March 2021

Abstract
Atmospheric rivers (ARs) are narrow and elongated regions of enhanced horizontal water vapour transport. Considerable research on understanding Northern Hemisphere ARs and their relationship with extreme precipitation has shown that ARs have a strong association with heavy rainfall and flooding. While there has been very little work on ARs in the Southern Hemisphere, global climatologies suggest that ARs are equally as common in both hemispheres. New Zealand in particular is located in a region of high AR frequency. This study aims to test the hypothesis that ARs play a significant role in heavy precipitation and flooding events in New Zealand. We used a recently developed AR identification method and daily station data across New Zealand to test for the concurrence of ARs and extreme rainfall. We found that, at each of the eleven stations analysed, at least seven to all ten of the top ten heaviest precipitation days between 1980 and 2018 were associated with AR conditions. Nine of the ten most damaging floods in New Zealand between 2007 and 2017 occurred during AR events. These results have important implications for understanding extreme rainfall in New Zealand, and ultimately for predicting some of the most hazardous events in the region. This work also highlights that more research on ARs in New Zealand is needed.

AbstractEel (Monopterus albus) is one of the fisheries commodities commonly used as food material in Indonesia. An innovation to attract more people to consume this high nutrient commodity is by diversifying eel into a galantine. This study investigated the effect of different eel composition and heat processing techniques on the sensory, nutrient, and microbiology quality of the eel galantine. Four different eel galantine formulas were examined, viz. steaming + 5% eel (A), steaming + 10% eel (B), grilling + 5% eel (C), and grilling + 10% eel (D). The sensory, nutrient, and microbiology quality of the samples were analyzed. The study indicated that the panelists preferred sample C’s appearance and aroma. The protein, moisture, ash, and fat content in all samples met the Indonesian National Standard (SNI) requirement. Sample B had higher vitamin A compared to sample D. The Total Plate Count parameter did not meet the requirement.

Abstract
Lake LautTawar is the only home for two endemic cyprinids, i.e. Rasboratawarensis and Poropuntiustawarensis, both are economically important species supporting food security and livelihood to local inhabitants. The present research was aimed to examine the applicability of EAFM, ecosystem approach to fisheries management in protecting endemic fishes in LLT. By referring to standard module, the domains and its indicators were ranked and weighted. Having given score to the domain, the composite domain and the sum of aggregation values of all domains, the performance of fishery management could be presented as flag model. Gap analysis was implied by contrasting EAFM’s recommendation against current achievement with refer to defined indicator. The applicability of EAFM to sustaining endemic fishes was assessed by means impact analysis under the scenario of three generic goals(1) augmenting the quality and quantity of habitat and sustainable utilization of fishery resources, (2) promoting higher socio-economic benefits, and (3) improving function and synergy among management institutions. The results showed that recommendations from EAFM’s model were all doable and that impact positively to sustaining endemic species. The challenges in implementation encompass authority, cooperation and coordination, stakeholders, invasive species and administration status of the lake.

Published: March 2021

Abstract
Pangasiid catfishes have most diverse morphotype among members in the family. In the past, misidentification often occurred for the species definition. After numerical taxonomy developed, the level of similarity or phenetic analysis was used to distinguish different taxa. While relationship and evolutionary evidence within species in Pangasiidae was analyzed based on the genetic data. The aim of the present study was to understand the congruency between phenetic and genetic analysis in family Pangasiidae. Euclidean distance was applied on phenetic analysis to produce phenogram of similarity. Sequencing of 12s rDNA was conducted to illustrate the genetic relationship. Both analyses showed that species member in Pangasiidae supported the genera proposed in the previous study. Four genera are in Pangasiiidae. The both analysis also support to the hypothesis of geological history, palaentology and models of other family in the observed area. The results confirmed that Pangasiidae may occurred 20 million years ago before separation of the islands with the mainland Asia.

Published: March 2021

Abstract
One of the successes in cultivation activities is by maintaining the quality of fish and their environment. Common carp (Cyprinus carpio L.) cultivation is one of the leading commodities in various regions, especially East Java. In Indonesia, there are several types of common carp strains, one of the seventh strains in Indonesia is the Punten strain from the Punten, Batu area of Malang. However, several cases show incidents of disease attacks, one of those diseases that often infect fish in Punten is the parasite Myxobolus sp. The observation of tissue lesion was used gills from common carp (C. carpio L.) taken from The Unit of Freshwater Cultivation Management (UPBAT) Punten, Batu Regency. Based on the results of observations, the visible lesion in the gill tissue, among, oedema, haemorrhage, the fusion of lamellae and vacuoles with scores and proportions of damage per field of view (%) in infected fish, respectively are, score 2 moderate (52%), 1 minor (25%), 1 minor (12%) and 2 moderate (18%). Based on the assessment, the scoring results show mild to moderate damage, so it is still classified as early-stage damage or it can also show the fish’s ability to recover in a good environment. However, the presence of infectious infections also allows the management of waste and water quality management in each pond, to maintain the environmental health of the common carp.

Published: March 2021

Abstract
The mangrove forest ecosystem is unique, both because of the subtract of siltation which results in less soil abrasion, high soil salinity, and experiencing a cycle of inundation by tides. Only a few plant species survive in such a place, and most of these species are unique to mangroves because they have undergone a process of adaptation and evolution. It is not widely known how far the mangrove areas are spread in Aceh. Therefore, research needs to be carried out with the aim of knowing the extent of the sustainability of mangrove management in terms of sediment characteristics. Information about the distribution, area and change of mangrove land cover can be determined by spatial analysis using a Geographical Information System (GIS) using ArcGIS. The method used in this research is the transect method and analysed based on the identification of mangrove species. Based on the analysis of the results of the study, it was identified that the mangrove species found in the research location of Peukan Bada sub-district (West Aceh Besar) consit of Rhizopora mucronata and Sonneratia alba, while the mangrove species found in Baitussalam (north Aceh Besar) were Rhizopora mucronata and Sonneratia alba. Meanwhile, based on observations with satellite imagery and location surveys, it was found that the mangroves in Baitussalam sub-district were denser and spread evenly than in the Peukan Bada area.
