The development of development in Indonesia is increasing along with population growth, as a result of the increasing development, environmental aspects need to be considered, because the use of cement, sand and coral (gravel) which is taken from nature must be limited in its taking or use. So the researchers used recycled coarse aggregates (RCA), from the remaining test objects of the Tribhuwana Tunggadewi University Laboratory malang as a substitute for the use of part of the coarse aggregate with a variation of 0%, 75% and fly ash waste as a partial substitution of cement use, this fly ash functioned as a filter to fill the cavities in the RCA. The methods used are experimental methods and the tests carried out are compressive strength testing and bending strength testing with a treatment / curing period of 7 days. The results of the study were carried out with the addition of fly ash to RCA in terms of the results of compressive strength testing showing that the maximum compressive strength of concrete is in the variation of fly ash 20% against RCA 0% with an increase in compressive strength of 21,535 MPa while the minimum compressive strength is at a variation of fly ash 30% against RCA 75% of 13,501 MPa, the compressive strength of concrete experiences a significant decrease in compressive strength often the addition of fly ash variations due to the wear value of RCA which is quite high. When compared, the test results of bending strength, which was reviewed from the load-deflection relationship of fly ash variations of 0% and 20% against RCA 75% had a maximum P load of 2600 kg, with small deflection. Therefore, fly ash and RCA can be used as materials in concrete mixtures with certain variations.

The purpose of this study was to determine the effect of the use of waste rice husk ash and viscocrete 1003 on the compressive strength and flexural strength of concrete with variations in the mixture of rice husk ash waste 0%, 25%, 30% and viscocrete 1003 0.6%. The results showed that the chemical content of rice husk ash that had been burned was high SiO2 (Silicon Dioxide), which was 75.5 ─ 87.9 % by weight, while the chemical content of unburned rice husk ash was SiO2 (Silicon Dioxide). Which is high that is equal to 86.9 ─ 94.7% by weight. The compressive strength test value of each variation of the specimen which is converted into 28 days of age is for variation 0% the average compressive strength value is 21.590 MPa, for variation 25% with an average compressive strength value of 15.635 MPa and 30% variation with the average compressive strength value is 11.486 MPa. So it can be concluded that the average compressive strength value from the 0% variation to the 25% variation has decreased by 0.05955%, while from the 25% variation to the 30% variation it has decreased by 0.0415%. The flexural strength test value in terms of the maximum average moment on the slab for each variation of the test object converted into 28 days of age is for 0% variation of 146.820 kN.m, for 25% variation of 165.760 Kn.m and variation of 30% of 170.490 Kn.m. So it can be concluded that the average flexural strength value from the 0% variation to the 25% variation has increased by 3.13%, while from the 25% variation to the 30% variation it has increased by 3.36%.

Microplastics have been found in the marine environment worldwide. Due to their very small size, it could be ingested by marine organisms from small size plankton to big size fish. The aim of this study is to assess the variability of microplastics in three different organs (gills, gastrointestinal tracts, and muscles) of commercial fishes in five different fishing ports in East Java Province, Indonesia. A total of 137 fish samples from 14 species were extracted to identify the types of microplastics. The microplastics found in the fish samples were mostly dominated by fiber, fragments, and a little quantity of film. In most species, the gills accumulated more microplastics compared to the gastrointestinal tracts and muscles. Gill is the organ that is highly exposed to the environmental conditions, therefore, it is more susceptible to the microplastic contamination. The results showed that there was an inverse relationship between the size of the fish and the occurrence of microplastics (P<0.05). Small size Sardinella lemuru contained more microplastics than bigger size fish such as Katsuwonus pelamis. The variability of microplastics found in this study showed important factors such as habitat, fish size, feeding behavior, and organ function which influenced the ingestion process of microplastic. This study also revealed the presence of microplastics were not only in the gills and gastrointestinal tracts of fish, but also in its muscles. Since this study targeted commercial fishes, further research is needed to know the possible impact on human consumption of fish containing microplastics.

The purpose of this study is to compare two methods of seismic load analysis, namely the static equivalent method and the dynamic response spectrum method. The case study is the integrated service building of Tribhuwana Tunggadewi University, Malang City which has 5 levels and is located in the 4 (medium) earthquake zone with moderate soil conditions. The research method used is descriptive quantitative. Collecting data of project drawings, as well as observations and interviews. Analysis method Equivalent static and dynamic response spectrum using software Staad Pro. The results compared are the base shear force (V), the floor lateral force (F), and the displacement or displacement. The result in the form of maximum internal force is analyzed to determine the capacity or ability of the profile to withstand combined loads. The comparison of base shear and displacement does not differ much from the two seismic analysis methods used. This insignificant difference is in accordance with the SNI that for structures with a height below 40m can be analyzed using equivalent statics, while in the case study it only has a height of 30m. So that the equivalent static analysis becomes more accurate to use because the analysis process is simpler than dynamic analysis, but for structures with a height above 5 floors it is recommended to use dynamic analysis. The results of the analysis of the ability of the steel profile on the cross section of the column and beam indicate a safe condition in carrying combined loads.

There are the same compound content, fly ash does not have the ability to bind, so it requires an alkaline activator for the polymerization reaction or binding reaction to occur. The alkali activators commonly used are sodium hydroxide and sodium silicate. The use of these materials makes concrete with fly ash known as geopolymer concrete. Geopolymer concrete is an alternative to conventional concrete, so it must have optimal strength like conventional concrete, therefore researchers are interested in testing the value of compressive strength, split tensile strength and mode of elasticity of geopolymer concrete using 10 molar alkali activator with a ratio of 3:2. for variations in the age of concrete 7, 14, 21, and 28 days; and the conversion value of geopolymer concrete using 10 molar alkali activator with a ratio of 3:2 for variations in the age of concrete 7, 14, 21, and 28 days. This research is an experimental study using variations in the age of concrete 7, 14, 21, and 28 days for geopolymer concrete using 10 molar alkali activator with a ratio of 3:2. The results of this study indicate that there is an effect of variations in the age of concrete on the value of compressive strength, split tensile strength, and modulus of elasticity of geopolymer concrete. Where the compressive strength, split tensile strength, and modulus of elasticity of geopolymer concrete at the age of 7 days are 31.40%; 35.44%; and 23.32% which at the age variation of 28 days increased by 100%. In addition, in this study, it is known that the conversion value at the age of 28 days for variations in the age of 7 days, 14 days, 21 days, and 28 days, respectively, is 0.31; 0.73; 0.97; 1.00 Keywords: Geopolymer Concrete, Compressive Strength, Modulus of Elasticity

Abstrak Perwujudan kebudayaan dapat berupa tingkah laku, alat hidup, bahasa, agama, kesenian, organisasi sosial, dan lain-lain, yang dihasilkan untuk membantu orang dalam kehidupan sosial. Desa Polaman merupakan salah satu kawasan budaya Kalirejo-Lawang, berada di daerah pegunungan yang subur serta memiliki banyak situs budaya, seni dan sejarah. Situs-situs ini mayoritas terkait dengan kelestarian alam. Studi ini dilakukan dengan tujuan untuk melakukan identifikasi komparasi tipologi rumah berdasarkan stratifikasi sosial yang ditinjau dari tingkat kekuasaan, kehormatan, ditinjau dari kekayaan. Metode penelitian yang digunakan untuk melakukan identifikasi komparasi tersebut adalah metode penelitian kualitatif yakni fenomenologi. Data identifikasi pada penelitian didapatkan dalam dua keknik pengumpulan data, yakni Observasi atau pengamatan serta wawancara mendalam atau depth interview terhadap responden yaitu warga, tokoh masyarakat, dan aparat desa Polaman. Dari hasil pengumpulan data secara kualitatif tersebut memperlihatkan bahwa tetua/sesepuh desa berada pada puncak kedudukan Hasil penelitian secara kualitatif menunjukkan bahwa ditinjau dari aspek kehormatan sesepuh desa berada pada puncak/kedudukan tertinggi. Hal ini terlihat dalam semua kegiatan dan ritual budaya di desa Polaman, warga memberikan penghormatannya pada sesepuh desa. Tetua desa biasanya memainkan peran penting dalam setiap ritual budaya. Sedangkan ditinjau dari segi tipologi hunian, dapat disimpulkan bahwa tingkat kehormatan tidak serta merta memberikan perbedaan yang signifikan. Hal ini berarti bahwa tipologi hunian yang dimiliki perangkat desa, sesepuh desa tidak jauh berbeda dengan tipologi hunian warga biasa. Perbedaan pada tipologi hunian hanya terlihat dalam material digunakan untuk pintu dan jendela, bahan atap dan dekorasi. Sedangkan ditinjau dari dimensi kekayaannya, masyarakat Polaman merupakan kelompok masyarakat yang homogeny, yakni kelompok masyarakat yang perbedaan tingkat kekayaannya tidak menonjol. Selain itu jenis profesi yang digeluti warga berpengaruh kecil terhadap tipologi rumah. Abstract The embodiment of culture can be in the form of behavior, tools of life, language, religion, art, social organization, etc., which are produced to help people in social life. Polaman Village is one of the cultural areas of Kalirejo-Lawang, located in a fertile mountainous area and has many cultural, artistic, and historical sites. These sites are mostly related to nature conservation. This study was conducted with the aim of identifying comparative typologies of houses based on social stratification in terms of the level of power, honor, in terms of wealth. The research method used to identify these comparisons is qualitative, namely phenomenology. Identification data in this study were obtained through two data collection techniques, namely observation and in-depth interviews with respondents, namely residents, community leaders, and Polaman village officials. The results of qualitative data collection show that village elders/elders are at the top of the position. Qualitative research results show that from the aspect of honor, village elders are at the top/highest position. This can be seen in all cultural activities and rituals in Polaman village, residents pay their respects to the village elders. Village elders usually play an essential role in every cultural ritual. Meanwhile, in terms of occupancy typology, it can be concluded that the level of honor does not necessarily provide a significant difference. This means that the typology of housing owned by village officials, and village elders, is not much different from the housing typology of ordinary residents. Differences in residential typology are only seen in the materials used for doors and windows, roofing materials, and decorations. Meanwhile, in terms of the dimensions of wealth, the Polaman people are a homogeneous group of people, namely groups of people whose differences in the level of wealth are not prominent. In addition, the type of profession that residents are involved in has little effect on the typology of the house. Keyword: identify; typological comparisons; social stratification
