The demand for environmentally friendly concrete mixtures is currently increasing due to an increase in global temperatures. Therefore, innovation is needed in the world of Civil Engineering to produce structures that can reduce global warming. One alternative that can be taken is by utilizing materials from environmentally friendly products such as Iron Slag. This study aims to determine the characteristics of the aggregate and to analyze the strength of the concrete mixture using Iron Slag as a substitute for fine aggregate. This research is an experimental study which was conducted in the Laboratory of Concrete and Structural Materials, Bosowa University. Variations in the test object were the levels of addition of Iron Slag with levels of 0%, 25% and 50%. The test object will be observed at the age of 28 days, where the number of test objects is 29 pieces. The tests carried out include testing the characteristics of the materials used, both coarse and fine aggregates, as well as testing the compressive strength of the concrete. Based on the results of the research analysis, it was concluded that Iron Slag waste met the criteria as fine aggregate for concrete mixtures.
Penelitian ini bertujuan menentukan pusat pelayanan perkotaan pada wilayah Kota Patalasang, Kabupaten Takalar, Sulawesi Selatan dengan menggunakan 3 (tiga) pendekatan analisis yaitu Zipf Law, Indeks Sentralitas dan Kernel Density. Ketiga analisis ini memiliki perbedaan yang sangat mendasar yaitu terkait data yang digunakan. Zipf Law analisis menggunakan data penduduk dalam penentuan orde kota. Analisis indeks sentralitas menggunakan data jumlah fasilitas dalam perkotaan. Sedangkan pada analisis kernel density, komponen yang digunakan adalah kepadatan bangunan atau kepadatan lahan menggunakan analisis GIS. Ketiga analisis ini memiliki hasil yang berbeda sehingga dalam menentukan pusat pelayanan perkotaan di Kota Patalasang, dengan menjumlahkan hasil dari ketiga analisis tersebut. Kelurahan Kalabirang di Kota Patalasang, Kabupaten Takalar terpilih sebagai orde kota pertama yang dapat disimpulkan sebagai pusat pelayanan kota secara keseluruhan.
Pengembangan Kabupaten Gorontalo Utara memerlukan pengembangan kawasan RS atau rumah sakit sehingga pemerintah Kabupaten Gorontalo Utara akan mengembangkan RS Type D pratama di Kecamatan Tolingula yang memerlukan kelayakan kawasan secara fisik untuk pembangunan kawasan serta mendukung pembangunan fisik di kemudian hari. Penelitian ini bertujuan untuk menganalisis kelayakan kawasan tapak rumah sakit dari aspek fisik kawasan rumah sakit dan sekitar kawasan rumah sakit. Dari hasil analisis tata ruang, tapak kawasan, SKL serta pengembangan sekitar kawasan, dapat dipastikan kawasan Rumah Sakit Type D Gorontalo Utara di Tolinggula layak dikembangkan dan dikerjakan.
Fiber reinforced polymer (FRP) has been developed to be applied for a strengthening of the deteriorated structures. In the form of a sheet, the FRP may be applied for the strengthening of the structures by bonding it to the concrete surface. Glass composed FRP (GFRP) sheet is most commonly used due to its relatively lower cost compared to the other FRP materials. GFRP sheet is applied externally by bonding it on the concrete surface. The strengthened structures should be monitored periodically to ensure the health of the strengthened structures. Regarding the development of monitoring system of the strengthened structure, it is important to study the delamination phenomenon of the bonded GFRP. Therefore the delamination mechanism is important to be clarified. Many studies have been done to investigate the bonding characteristics of GFRP sheet under direct tensile loading. However, the studies on the bonding characteristics of GFRP sheet on the strengthened beams due to flexural loadings are still limited. A series of concrete beams strengthened with GFRP sheet on extreme tension surface were prepared. The beam specimens ware loaded under four-point bending test gradually up to the ultimate capacity. Results indicated that prior to final delamination, a local delamination occurred which was indicated by the suddenly decreasing of an applied load. The delamination of the GFRP sheet may be initiated by the flexural cracks occurred on the beams.
In adolescence curiosity about sexual problems is very important in the formation of new relationships that are more mature with the opposite sex. This research was carried out with the aim of obtaining in-depth information about the Phenomenon of Sexual Behavior in Youth Youth, the result of adolescent sexual behavior, as well as forms of prevention of sexual behavior in adolescents in Bantaeng district. The type of research used is qualitative with a descriptive approach. Data collection techniques use Observation, Interview, and Documentation, while data analysis techniques use qualitative descriptive with stages of data reduction, presentation, and conclusion. The results of this study indicate that there is some background information about the occurrence of sexual behavior, namely the gadgad factor, the emergence of smartphones that provide freedom of social media and providers that provide low-cost social media services, clearly causing adolescents to forget the social boundaries they should know. Factor lack of knowledge, One of the problems of adolescents if lack of pranika sexual knowledge is unwanted pregnancy, unsafe abortion and also venereal disease. Peer factors are peer groups as places of interaction have a role for social life and adolescent education. Adolescent free association is one form of perilku form which deviates "Free" in question is to exceed the existing eastern boundary norms. It is often this kind of promiscuity that we often hear both within and outside the mass media. As for the form of prevention of sexual behavior, there must be good cooperation with related parties on how to improve the quality of knowledge about the impact of sexual behavior, so that the problem of lack of knowledge can be reduced. Curiosity is a turbulent feeling that can arouse people's curiosity. The curiosity usually develops when you see your own state or interesting surroundings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
