Abstract

The shear strength value is one of the important points in calculation of slope stability. One way to obtain the shear strength value is to do a direct shear test in laboratory. Like the cliff reinforcement study at Utama Mandala Uluwatu temple which is currently experiencing crack, it is necessary to test the shear strength of the limestone material at the cliff of the temple . There is no limestone testing equipment in the laboratory of the Civil Engineering Department, so that innovation is needed on the existing sliding test equipment. In this study innovation was carried out on how to test the soil shear strength so that it could be used to test the limestone shear strength. The test is done by moving two limestone surface that have been formed based on the mold tool which shape is circle. The shear strength slope at Uluwatu temple, which is currently experiencing crack in dry condition is . The shear strength value is used for calculating slope stability at Uluwatu Temple which is currently experiencing crack wich . The calculation used is curved slope stability by only calculate the life load and dead load. From the calculation of the stability of the slope, the safety factor is 1.15.

Abstract

ABSTRACT Biodiversitas ikan-ikan air tawar lokal asli Indonesia sangat berlimpah namun belum banyak dimanfaatkan dalam budidaya. Pemanfaatan secara langsung masih dalam taraf penangkapan di alam yang dikhawatirkan dapat membahayakan populasinya di alam. Salah satu alternative untuk pencegahannya adalah dengan upaya meningkatkan budidaya dan mengurangi penangkapa The biodiversity of local freshwater fish native to Indonesia is very abundant but has not been widely used in aquaculture. Direct use is still within the level of capture in nature which is feared to endanger its population in nature. One alternative to prevention is to increase cultivation and reduce overfishing. Before carrying out fish farming first in domestication so that the fish are accustomed to living in a controlled environment. Feeding habits and growth Nyalian fish eat feed that floats or does not immediately sink to the bottom of the waters. It also corresponds to the position of his mouth looking up obliquely and his habits of life on the surface of the waters. The sampling method is Nyalian fish samples collected at two locations and data analysis on this research using SPSS. The growth of Rasbora lateristriata fish during domestication showed significant results, namely the absolute growth of the calculated t-test value of 16.948 with a significance level of 0.000. The growth of the total length with a calculated t-test value of 14.091 with a significance level of 0.000. Weight growth with a calculated t-test value of 9.045 with a significance level of 0.000. The relationship between length and weight shows significant results where the increase in standard length will be followed by weight growth. Water quality during the study, namely pH, DO and temperature is still following the life of Italian fish. The results of the study show that Nyalian fish can adapt to the artificial environment n yang berlebihan. Sebelum melakukan budidaya ikan terlebih dahulu di domestikasi agar ikan terbiasa hidup dilingkungan terkontrol. Kebiasaan makan dan pertumbuhan Ikan Nyalian memakan pakan yang terapung atau tidak langsung tenggelam ke dasar perairan. Hal itu juga sesuai dengan kedudukan mulutnya yang menengadah miring ke atas dan kebiasaan hidupnya di bagian permukaan perairan. Metode pengambilan sampel adalah Sampel ikan Nyalian dikoleksi pada dua lokasi dan Analisis data pada menelitian ini menggunakan SPSS.Pertumbuhan ikan Rasbora lateristriata selama domestikasi menunjukkan hasil yang signifikan yaitu pertumbuhan mutlak nilai uji t hitung sebesar 16,948 dengan tingkat signifikansi sebesar 0,000. Pertumbuhan panjang total total dengan nilai uji t hitung sebesar 14,091 dengan tingkat signifikansi sebesar 0,000. Pertumbuhan berat dengan nilai uji t hitung sebesar 9,045 dengan tingkat signifikansi sebesar 0,000. Hubungan panjang dan berat menunjukkan hasil yang signifikan dimana pertambahan panjang baku akan diikuti oleh pertumbuhan berat. Kualitas air selama penelitian yaitu pH, DO dan suhu masih sesuai dengan kehidupan ikan Nyalian.Dari hasil penelitian menunjukkan bahwa ikan Nyalian mampu beradaptasi pada lingkungan buatan

Abstract

Koi fish (Cyprinus carpio) is an ornamental fish that has a beautiful body shape and color, so it has high economic value. Indicators of beauty in ornamental fish can be seen in the brilliant color, physical shape and completeness, behavior, and health conditions or stamina. These koi fish are often used as aquarium decorations and are art for consumption enthusiasts. The community demands the beauty of Koi fish, so farmers need to maintain the color of ornamental fish by providing feed that contains color pigments. Carotenoids are the main natural components that make color pigments, positively affecting red and orange colors. Carotenoids can come from spirulina, which contains phycocyanin, chlorophyll-a, and carotene. Carotene is composed of xantophyll (37%), carotene (28%), and zeaxanthin (17%). Providing a source of color pigment in fish feed is one of the efforts to get a bright color evenly distributed in fish. Feeding containing 8% spirulina was effective in increasing color pigmentation in the red swordtail (Xiphophorus helleri). The addition of 1.2% spirulina flour to artificial feed significantly increased color intensity and was the highest result in increasing color intensity of Koi fish.

Abstract

Community Service activities are carried out in Wanagiri Village, Sukasada, Buleleng which has abundant water sources but has not been utilized optimally, especially for the Fisheries sector. Fish Group activities are weakening due to lack of motivation and the location for Fisheries Activities is very difficult to reach. The purpose of this community service is to provide solutions to the Merta Lestari Fish Group (Partners) to actively re-cultivate tilapia with the Biofloc system, providing Training on Tarpaulin Pond Making. The method used is by means of Interview, Counseling, Face-to-face, and Direct Practice. With this method, it is hoped that Partners will get knowledge and solutions to the problems faced. Activities are carried out in stages, the First Stage, the Team Provides Counseling, the Second Stage, the Team provides direct practice on making Tarpaulin Pools, conducting evaluations so that Partners really understand, and after that carrying out Coaching. The output targets to be achieved in this activity are publishing the results of activities in international journals, publishing in print/electronic media, making 4-minute activity videos, and obtaining IPR Certificates.

Abstract

Tilapia (Oreochromis niloticus) is a type of aquaculture commodity that has high economic value as a freshwater consumption fish in the world. Efforts to increase the quantity and quality of commercial feed have an impact on the operational costs of intensive fish farming, namely more than (60-70%) of the total production costs. One effort to overcome dependence on imported feed raw materials is the use of local raw materials. The local raw materials used must have high nutritional value, be non-toxic, relatively cheap, very abundant and not compete with human needs, including Japanese papaya leaves. The use of Japanese papaya leaf flour as a source of carbohydrates and protein in fish feed cannot be done optimally because it contains high levels of fiber and tannin which can bind the minerals needed by fish.

Abstract

Mangrove forest ecosystems are vegetative communities found in tropical and subtropical estuaries and shallow coastal lagoons. They are mostly composed of several types of mangrove trees that can thrive in muddy beach tidal zones. The science and art of remote sensing involves analyzing data collected using instruments without coming into direct touch with the thing, location, or phenomena being researched in order to learn more about it. Sentinel-2A is a medium spatial resolution satellite image with a wide swath that can be used for studies on land cover monitoring, including vegetation, soil, and water, as well as water networks and coastal areas. It revisits the same location every 5 days, as opposed to Landsat's 16-day interval. The research findings indicate that there was an increase in the development of mangrove density between 2019 and 2023. Specifically, the total area of mangrove forests rose from 118.59 Ha in 2019 to 145.44 Ha in 2023. These developments are displayed in the table below
