Abstract This time fish farmers often face constraints on the high price of commercial feed which results in low profits for the farmers. One solution to reduce artificial feed is periodic starvation. Starvation can reduce and increase feed efficiency while increasing production and fish can grow equally without fasting. The purpose of this study was to determine the growth and survival of periodically fasted tilapia (Oreochromis niloticus) in Bedeng Munir Village, South Pagar Alam. The method used in fish farming consisted of two treatments, that is P0: control and P1: fasting treatment (fish were given commercial feed for 4 days and fasted for 1 day). The parameters observed were absolute length growth, absolute weight growth, total feed consumption, feed efficiency, survival, and water quality. The results showed that the P1 treatment produced the highest absolute weight growth of 16.5 g, the highest absolute length growth was 1.35 cm, the lowest amount of feed consumption was 1540 g, the highest feed efficiency was 204.94%, the survival rate was 89. %,. While water quality in both the treatment is still in the range of tolerance for tilapia as temperature 21.4 to 24.2 0C and pH 7.6 to 8.1.KeywordsGrowth, tilapia, starvation, survival.

Shrimp fishing is done by trawling in the deep waters of Antalya and Finike Gulfs. The shrimp species generally caught during this fishing are Aristaeomorpha foliacea, Aristeus antannatus, Plesionika edwardsii, P. martia.  Besides these species, Pasiphea multidentata and P. sivado, which have no economic value, are rarely caught. Two different shrimp species were caught during trawling in the 400-500 m deep waters of Finike Bay on February 7, 2022. Since the fishermen did not know the shrimp species they caught, they wanted the species to be identified. It has been determined that these shrimp species caught in the deep waters of Finike Bay are Oplophoroidae family members i.e. Acanthepyra eximia and A. pelagica. These caught shrimps are pelagic species. With the discovery of these species in the Finike Bay, two more species were added to the Decapod fauna of the Finike Bay.

PPN Karangantu is one of the fish landing sites in Serang City, Banten Province. One of the most commonly landed fish species at PPN Karangantu is mackerel. Several fishing gears are used by Karangantu fishermen to catch mackerel, including single monofilament gillnets, boat lift nets, lift nets, and lines. While mackerel fishing efforts in the 2017-2021 timeframe are likely to increase, specific management measures for mackerel fishery at Karangantu PPN have not been implemented. The purpose of this study was to determine the CPUE trend for mackerel fisheries in the 2017-2021 timeframe and to identify the dominant types of fishing gear used in mackerel fishery activities. The data used in this study were obtained from the PPN Karangantu statistical report and field observations. The collected data was processed and analyzed using CPUE and descriptive analysis. The results showed that the CPUE trend for mackerel from 2017 to 2021 tends to increase sustainably, with the single monofilament gillnet being the dominant fishing gear used in mackerel fishing.

Lampung is one of national marine tourism destination. Seagrass is one of fragile coastal ecosystem and it is a habitat and feeding ground for a number of Echinoderms species.  Echinodermata are nutrient recyclers that will in turn provide benefits to the seagrass ecosystem. This research aimed to assess the community structure of Echinoderms and seagrass as well as the relationship between Echinoderms abundance, seagrass densities, and water quality in Mahitam Island and Ketapang Beach. Observations were conducted at 7 stations, namely 3 stations on Ketapang Beach and 4 stations on Mahitam Island. Observations included the type and number of echinoderms, as well as the type, number of individuals, and number of seagrasses stands. Habitat quality that was observed were included water quality such as temperature, salinity, pH, DO (dissolved oxygen), current speed, brightness, and TOM (total organic matter) and also observed substrate type at each station. The result elucidated nine species of echinoderms and 4 species of seagrasses were found in both study sites. The average value of Echinoderms diversity index in Mahitam Island and Ketapang Beach was low. The uniformity index of Echinoderms in Mahitam Island was medium and Ketapang Beach was low. The dominance index of Echinoderms on Mahitam Island was categorized as low and Ketapang Beach was considered high. There was a domination of an Echinoderms species in some stations. The association between Echinoderms abundance, seagrass density and habitat quality in both locations showed a positive relationship and was influenced by the habitat quality parameters of seagrasses.

Indeks vegetasi merupakan parameter yang diperoleh dari citra satelit untuk menggambarkan aspek kerapatan vegetasi di suatu daerah. Kawasan Jember bagian selatan berada di daerah dengan kerapatan vegetasi lebat dan masuk dalam formasi vulkanik yang menjadi indikasi keterdapatan mineral alterasi.  Alterasi mineral terbentuk dari proses ubahan pada mineral akibat adanya proses kompleks yang meliputi perubahan secara mineralogi, kimia, dan tekstur pada batuan. Tujuan penelitian yaitu untuk mengidentifikasi keterkaitan perubahan indeks vegetasi dengan keberadaan mineral alterasi. Untuk menghindari kesalahan pengamatan karena kawasan bervegetasi lebat, maka citra Sentinel-2A yang digunakan lebih dari satu waktu (multitemporal). Proses pengolahan data meliputi koreksi geometrik dan atmosferik, perhitungan NDVI (Normalized Difference Vegetation Index), dan observasi lapangan. Rata-rata nilai indeks vegetasi pada April 2021, Juni 2022, dan Juli 2022  masing-masing sebesar 0,5749, 0,6722, dan 0,6316. Persentase tutupan lahan dari tiga series data didominasi oleh kerapatan vegetasi tinggi sampai sangat tinggi dengan nilai di atas 70%. Jenis penggunaan lahan pada kerapatan vegetasi yang tinggi yaitu hutan, perkebunan, sebagian taman nasional, dan lahan pertanian. Mineral yang teridentifikasi antara lain kuarsa, kaolin, piroksen, plagioklas, dan lain-lain. Mineral alterasi argilik ditemukan di kawasan dengan kerapatan vegetasi yang sangat tinggi.

Published: November 2023

This study investigates the utilize of the iteration of matrix numerically to get the divergence speed of an aircraft tapered-unswept wing via using method of strip theory (without finite span correction and with finite span correction). The 2-D fluid flow across the wing airfoil section is assumed by the aerodynamic strip theory and then integrated over wing span. In the present work, first the tapered unswept wing is divided into four Multhopp’s stations. Then, elastic properties of this wing in relation to torsional influence coefficients related with this four Multhopp’s stations have been evaluated. Second, equations for equilibrium are constructed as integral equations. Then, an appropriate aerodynamic theory in the form of strip theory was addressed, as well as the technique of solution for determining the divergence speed. Finally, using strip theory, the integral equation has been expressed in matrix form. Iteration of matrix has been done using MATLAB environment to reach for the solution to converge. Also, an increase of 15% in torsional stiffness of aircraft wing has been considered to illustrate its effects on torsional divergence speed of aircraft wing. The attained results are going to be helpful in understanding of wing instability for modern aircraft designer.
ChatGPT on the Einstein-Podolsky-Rosen Paradox
Authors: Stávek Jiří
Published: November 2023

This is my first attempt to communicate with the ChatGPT on the Einstein-Podolsky-Rosen paradox. ChatGPT reacted promptly with a good overview of this very wide topic. ChatGPT during our half hour conversation concluded that there is still room for the further development of the EPR paradox because this research field is far from the final theory. However, ChatGPT was skeptical to search for the missing element of the physical reality in papers of Old Masters working between 17th and 19th centuries. (One potential candidate for a more general physical theory of the EPR paradox can be found in the overlooked works of Old Masters working in the period of the 17th–19th centuries).

Authors: Indriyani Laely Laely
Published: November 2023

It is a new phenomenon in Indonesia regarding cases involving several Muslim officials and politicians. In order to anticipate and eradicate corruption, there is an alternative that can be developed in Islamic Religious Education that is a neuroscience approach using the Anti-Corruption Education strategy at the Early Childhood Education level. The research used is a literature study by reviewing journals that are relevant to the author's research, using secondary data, namely data obtained indirectly. The data needed in this study were taken from documents related to research. The data collection technique was carried out by examining and analyzing books and journals with rules related to the implementation of Anti-Corruption Education through fun learning activities for children carried out by participating in the National Movement for Learning I'm an Honest Child while the implementation of Islamic Religious Education is carried out scientifically and holistically integratively but both not yet integrated. Integration is carried out between Anti-Corruption Education and Islamic Religious Education by using the expansion of various forms of corruption related to the themes conveyed during learning activities. Islamic Religious Education is based on neuroscience learning theories. The data analysis technique used is qualitative analysis. The results of the study show that an educator can apply a neuroscience approach by integrating Anti-Corruption Education and Islamic Religious Education through learning activities that are used as habituation programs, carried out repeatedly and continuously with various learning methods so that honest character recognition can be implemented properly. The educator also stimulates and facilitates introducing this honest character according to the stages of early childhood development. The author's argument states that there is a neuroscience correlation, Islamic Religious Education and Anti-Corruption Education in implementing honesty and the development of Moral and Religious Values in early childhood can develop more optimally. Keywords: Islamic education, brains, goals, character, anti-corruption, and early childhood
