Abstract

Plankton adalah komponen paling penting dalam kehidupan akuatik yang berperan penting sebagai mata rantai paling awal dalam rantai makanan. Plankton menjadi dua yaitu plankton hewani disebut sebagai zooplankton dan plankton tumbuhan disebut sebagai fitoplankton. Tujuan dari penelitian ini yaitu untuk mengetahui struktur komunitas plankton diperairan keramba jaring apung (KJA). Penelitian dilakukan pada bulan Februari- April 2022 di perairan Teluk Lampung. Metode yang digunakan adalah metode purposive sampling. Pengambilan sampel dilakukan berdasarkan stasiun, yaitu stasiun 1 (terletak di lokasi yang mempunyai jumlah KJA lebih banyak), stasiun ke 2 (terletak di lokasi jumlah KJA yang lebih sedikit), stasiun ke 3 (terletak di lokasi sedang tidak ada KJA). Data yang diperoleh dianalisis Keanekaragaman dan Dominansi. Indeks Keanekargaman yang paling tinggi ditemukan di stasiun 3 yang mencapai 3,26 pada stasiun 3, sedangkan Nilai Indeks Dominansi yang paling tinggi mencapai 0,047 pada stasiun 2. Jumlah spesies yang ditemukan pada keramba jaring apung sebanyak 29 genus, 17 fitoplankton dan zooplankton sebanyak 12 genus. Fitoplankton yang mendominansi adalah Skeletonema dan zooplankton yang mendominasi adalah Naupilus.

Abstract

Handedness is a human asymmetry defined as the preference for using one hand to perform unimanual activities. It has been associated with various cognitive abilities, including visuospatial skills. Visuospatial ability is interpreted as an individual's capacity to understand the relationship between the visual and spatial aspects of a specific object in two or three dimensions and space. Institut Teknologi Sumatera (ITERA) is one of the state universities primarily focused on science and technology, requiring students to develop their visuospatial skills. This research aims to analyze the differences in visuospatial ability between students with a preference for using the right hand and those with a preference for using the left hand at Institut Teknologi Sumatera. The study utilized interview methods through handedness questionnaires, visuospatial ability questionnaires, and hand strength measurements using a hand dynamometer. The respondents in this research numbered 393 individuals, aged between 17-23 years. The study revealed that there were 30 left-handed individuals, comprising 18 males and 12 females. Ambidexterity was found in 11 males and 13 females, subsequently categorized as left-handed in the analysis. The results of the visuospatial ability test indicated that the average scores of left-handed respondents were better than those of right-handed respondents (46.39 > 43.39). Male respondents exhibited superior visuospatial ability compared to females (estimate: 1.3798; p-value: 0.0272).

Abstract

Plankton is the most important component in aquatic life which plays an important role as the earliest link in the food chain. Plankton into two, namely animal plankton is referred to as zooplankton and plant plankton is referred to as phytoplankton. The purpose of this study was to determine the structure of the plankton community in floating net cages (KJA). The research was carried out in February-April 2022 in the waters of the Floating Net Cages in Lampung Bay. The method used is purposive sampling method. Sampling was carried out based on stations, namely station 1 (located at a location with a higher number of KJA), station 2 (located at a location with a smaller number of KJA), station 3 (located at a location where there were no KJA). The data obtained were analyzed for Diversity and Dominance. The highest diversity index was found at station 3 which reached 3,26 at station 3, while the highest dominance index value reached 0,047 at station 2. The number of species found in floating net cages was 29 genera, 17 phytoplankton and 12 genera of zooplankton . The dominant phytoplankton is Skeletonema and the dominant zooplankton is Naupilus.

Abstract

Orthoptera are important members of almost all terrestrial ecosystems, playing roles as both consumers and prey. Diversity refers to the various species found within a particular area. This study aims to determine the diversity index, dominance index, and evenness of the order Orthoptera at the Institut Teknologi Sumatera. Data collection on Orthoptera diversity was conducted and identified in the Zoology Laboratory at Institut Teknologi sumatera. Purposive sampling was used as the sampling technique, based on specific considerations. Observations were carried out at four locations around Institut Teknologi Sumatera and analyzed using diversity index, dominance index, and evenness index formulas. This study found 12 genera from the order Orthoptera. The diversity of Orthoptera at ITERA was categorized as moderate, with the diversity index (H’) values recorded as follows: Station I (1.879); Station II (1.765); Station III (1.626); and Station IV (1.843). No dominant individuals were found at any station. The evenness index at ITERA was categorized as high, with values of 0.784 at Station I; 0.767 at Station II; 0.678 at Station III; and 0.742 at Station IV, where Station I had the highest evenness value
