Growth and Exploitation Rate of Squid (Uroteuthis sp.) Caught in the Waters of Malacca Strait Belawan, North Sumatra
No full textSquid (Uroteuthis sp.) is a commercially important commodity in the fisheries activities of the Malacca Strait waters. However, squid production has been declining, and information regarding its growth and exploitation rate in this region remains limited. This study was conducted from June 2024 to September 2024 with the aim of determining the morphology, growth, and exploitation rate of squid (Uroteuthis sp.) in the Malacca Strait waters. The results showed the presence of two squid species in the Malacca Strait: Uroteuthis chinensis and Uroteuthis duvaucelii. Growth parameter estimation using the Von Bertalanffy method for U. chinensis in the Malacca Strait waters revealed an asymptotic length (L∞) of 591.4 mm, a growth coefficient (K) of 1.01 per year, and an age at zero length (t0) of -1.1595. For U. duvaucelii, the parameters were L∞ of 413.5 mm, K of 1.30 per year, and t0 of -1.2305. The growth pattern of Uroteuthis sp. in the Malacca Strait waters exhibited negative allometric growth (b < 3), with the equation W = 0.004L2,0381 for U. chinensis and W = 0.0023L2,1088 for U. duvaucelii. The exploitation rates for U. chinensis and U. duvaucelii were -0.5274 and -3.7056, respectively, indicating that the exploitation rate of Uroteuthis sp. in the Malacca Strait waters does not exceed the optimum value (0.5).82 PagesSkripsi Sarjan

Impact Strength of Heat-Cured Acrylic Resin after The Addition Of Alkalized and Dyed Nanoparticle Powder of Barangan Banana Stem (Musa Acuminata Colla)
No full textHeat-cured acrylic resin as a denture base that is potentially subject to sudden impacts, such as falling while cleaning dentures. To prevent the possibility of easy fracture due to impact, it is necessary to increase the impact strength of acrylic resin. One of the ways is to add reinforcing materials such as natural fibers. The addition of natural fibers, such as banana stem fibers, as a reinforcement for acrylic resin is expected to improve and enhance the mechanical properties, thus strengthening the resistance of acrylic resin to impact. The purpose of this study was to determine the difference in impact strength of heat-cured acrylic resin after the addition of alkalized and dyed barangan banana stem fiber nanoparticle powder (Musa acuminata Colla) at concentrations of 0.5%, 1%, and 1.5% weight.
The research samples were made of heat-cured acrylic resin 80x10x4 mm as many as 10 pieces for each treatment group, namely, the group without fiber powder addition (I), the group added fiber powder with 0.5% weight (II), fiber powder 1% weight (III) and fiber powder 1.5% weight (IV) with ratio of fiber powder: polymer: monomer, namely 0.025 gr: 4.975 gr: 2.5 ml (II), 0.05 gr: 4.95 gr: 2.5 ml (III), and 0.075 gr: 4.925 gr: 2.5 ml (IV). The fibers were taken from the middle part of the banana stem, alkalized with 5% NaOH at a temperature of 25oC for 1 hour, then dyed with 15% red dragon fruit extract, ground, dried, and underwent the ball milling process to obtain nanoparticle size. Nanoparticle powder was added to the resin powder and mixed with monomer liquid, packaged, then cured, then the sample was polished and finalized. Impact strength was tested using a Charpy impact tester with a swing angle of 150o and a hammer mass of 0.71 kg.
The mean and standard deviation of impact strength values in groups I, II, III, and IV were 0.0095±0.0019 J/mm2, 0.0131±0.0032 J/mm2, 0.0139±0.0035 J/mm2, 0.0145±0.0026 J/mm2, respectively. ANOVA statistical test showed that there was a significant difference in impact strength in heat-cured acrylic resin after the addition of 0.5%, 1%, and 1.5% weight of barangan banana stem fiber powder with p-value of 0.002 (p <0.05). Post-hoc test showed that there was a significant difference (p <0.05) between groups with and without addition. It can be concluded that the impact strength of heat-cured acrylic resin increases with the addition of nanoparticle powder of barangan banana stem fiber and the addition of 1.5% weight is the powder concentration with the highest impact value.90 PagesSkripsi Sarjan
A Comparative Study Of Clustering Algorithms For Optimizing The Distribution Of The Indonesia Smart Card (KIP-K) Aid Program In Indonesia
No full textPoverty and limited access to education remain major issues in Indonesia, particularly in determining the recipients of educational assistance such as the Kartu Indonesia Pintar Kuliah (KIP-K). This study aims to optimize the determination of KIP-K recipients by using regional clustering based on socio-economic indicators, such as poverty levels and school dropout rates. The primary objective of this research is to identify areas that require more attention in the distribution of KIP-K assistance, ensuring it is more accurately targeted. Three clustering algorithms used in this study are K-Means, DBSCAN, and Agglomerative Clustering. The analysis results show that Agglomerative Clustering produces more distinct and cohesive clusters, with the highest Silhouette score of 0.6144, indicating clearer regional divisions. Meanwhile, K-Means, with a Silhouette score of 0.6128, also delivers satisfactory results, although not as optimal as Agglomerative Clustering. DBSCAN shows limitations in grouping data, as most regions are identified as noise. As an implementation of this research, an interactive Streamlit dashboard has been developed to visualize the clustering results and facilitate decision-making in the distribution of KIP-K assistance. This dashboard serves as an effective tool to enhance the transparency and efficiency of KIP-K distribution, supporting more precise decision-making.95 PagesSkripsi Sarjan

Evaluation of the Drainage System on Jalan Bunga Ester, Medan Selayang District
No full textAn inadequate drainage system can cause waterlogging and flooding, especially
in urban areas with high rainfall and rapid development. This study aims to evaluate
the capacity of the drainage channel on Bunga Ester Street, Medan Selayang
District, to determine whether the existing channels can accommodate the rainfall
discharge according to the hydrological characteristics of the area.
The analysis methods include collecting rainfall data, measuring the
dimensions of existing channels, and calculating the design discharge using the
rational method. The actual channel discharge is calculated based on the geometric
profile and slope of the channel. The evaluation results show that most segments of
the channel are unable to accommodate the design discharge, especially during
rainfall events with certain return periods, thus requiring redesign or improvement
of channel dimensions. This study recommends increasing channel capacity and
implementing sustainable drainage management to reduce the risk of flooding in
