Performance Analysis of Earthquake-Resistant Building Structures with Conventional Columns and Flat Columns
Get PDFThe structural integrity of a building depends on the ability of its column components to support the loads above them. The strength of a column is greatly influenced by its shape and dimensions. This study aims to analyze the performance of earthquake-resistant building structures with conventional columns and flat columns. This research was conducted by modeling two variations of an 8-story building structure using ETABS software, which are Model 1 with conventional columns and Model 2 with a combination of conventional columns and flat columns using L-shaped and T-shaped columns. The analysis of earthquake loads was performed by using the response spectrum analysis method, while the structural performance and the collapse mechanism of the building were performed by using the pushover analysis method. The results showed that Model 1 had smaller values of internal force, base shear, displacement, and inter-storey drift than Model 2. The results of the structural performance level in both models had the same level, which is Damage Control (DC). The structural collapse mechanism in Model 1 has qualified the requirement of strong column weak beam, while Model 2 has not met this requirement and falls into the column sway mechanism because the first collapse happened in columns. Based on the statistics analysis, there is no significant difference between Model 1 and Model 2, but in terms of maintaining the room area and aesthetic interior, Model 2 with flat columns has more value

Implementasi Solar Charging Controller Pada Penggerak Sirkulator Air Kolam Ikan di Kampung Setaman, Kota Depok
Get PDFThe community needs-based community service activity of the Industrial Electronics Study Program, Department of Electrical Engineering (JTE) in Kampung Setaman, is an effort to solve the problems of the residents starting from the Covid-19-2020 period, where the residents of Kampung Setaman have around 100 pools, currently the remaining ones have decreased. In the 80s, most homeowners objected to paying for electricity to drive pump motors in fish ponds. As a result, some of the fish ponds died due to inactivity, ironically fish became a source of protein for the residents. Based on this, a solution emerged to create a Solar Power Generation System (PLTS). This is to provide solutions to residents' problems, so that the burden of electricity payments is reduced. Based on the objections to the electricity payment costs that emerged, the design of the PLTS included planning and empowering the pool as a healthy facility and business plan. This PLTS design refers to the concept of electricity distribution from one solar cell house (consisting of 4 cells) to 8 battery units. The aim of this PPIBM is to build a small-scale PLTS of 100 WP (400 WP), with the target of being able to activate 8 units of DC water pump motors for fish pond water circulation. The indicator of PPIBM's success is ensuring the process of storing unused electrical energy from solar cells for each battery. The solar cells are installed on a holo stand at a certain angle according to the direction of the sun, the position can be adjusted. Technical considerations get maximum solar intensity and excess energy can be stored in batteries. PLTS installation refers to the solar cell manual book, the service provider's contribution to the electronic system is so that the electrical energy activates the motor and some of it is stored in the battery (30%). The performance of the PLTS electrical system activates 8 motors during the day, 3 batteries supply electricity at night. The results of this installation are 4260 W (100 Ah) of power.The community needs-based community service activity of the Industrial Electronics Study Program, Department of Electrical Engineering of Politeknik Negeri Jakarta in Kampung Setaman, Depok, is an effort to solve the problems of the residents starting from the Covid-19-2020 period.

EXPERIMENTAL STUDY ON STEEL AND POLYPROPYLENE FIBERS MORTAR BOND STRENGTH UNDER UNIAXIAL TENSION
Get PDFThe present study aims to investigate the bond behavior between fibers and mortar matrix in fiber-reinforced concrete, which was explored through a uniaxial tension test. The bond behavior was studied for different types of embedded fibers: steel fibers, polypropylene fibers, and hybridizations of steel and polypropylene fibers. The mixture proportion was determined based on the absolute volume method with a water-to-binder ratio (w/b) of 0.29 to achieve high-strength mortar. The high-strength mortar was cast by utilizing an industrial waste by-product of both silica fume and fly ash as a partial cement replacement. The compressive strength and uniaxial tension tests on high-strength mortar were conducted at the ages of 28 and 140 days. The long-term bond-strength behavior was investigated at the age of 140 days. The results showed that the average compressive strengths of hardened mortar on 28 and 140 days were 54.82 MPa and 69.37 MPa, respectively. Whereas, the average fiber-mortar bond strengths with steel, polypropylene, and hybridized fibers were 8.62 MPa, 8.37 MPa, and 7.30 MPa, respectively, at 28 days and 11.22 MPa, 10.21 MPa, and 11.82 MPa, respectively, at 140 days. Compared to the equivalent bond strength of the steel fiber, the polypropylene fiber had an equivalent bond strength of 2.90% and 9.00% lower at the ages of 28 and 140 days. Meanwhile, the equivalent bond strength of hybridized fiber was 15.31% lower than that of steel fiber; however, the long-term behavior of the hybridized fiber showed its performance was about 5,35% higher than that of steel fiber at 140 days
Menangkap Photographic Moments di Pelelangan Ikan Muara Baru melalui Pendekatan Komposisi dan Etnografi Fotografi
Get PDFIn photography studies, composition is essential in capturing images to arrange visual elements within the photo frame. There are at least nine compositions that we analyze in this paper. These compositions are important for communicating the message the photographer wants to convey to the audience, thus creating a dialogic communication effort. This paper uses traders at the Fish Auction in Muara Baru, Jakarta, as the subject of photography, and the resulting photos become photographic moments in photographic ethnography. By capturing photographic moments through the correct composition, this paper demonstrates that photographs can produce meaning from the moments captured by the camera. This study is called visual ethnography, in which ethnographic photography is included as a sub-discipline that emphasizes the interpretive aspect of the subject's and object's expression in photos. Photographs with adjusted composition are not only seen as objects without meaning, but also as subjects that convey the expression of meaning and cultural communication. This can be a way for anthropologists and communication scholars to understand the socio-cultural phenomena of the communities being studied. The research in this paper finds that the combination of photography studies on composition and the method of ethnographic photography is still rarely undertaken, even though the study of photographs as both subjects and objects can provide a comprehensive picture of 'socio-cultural' conditions.In photography studies, composition is essential in capturing images to arrange visual elements within the photo frame.

METAFORA BERANJAK DEWASA DALAM LIRIK LAGU “TAKUT” KARYA IDGITAF: KAJIAN LINGUISTIK KOGNITIF
Get PDFThis study aims to analyze the metaphor of "beranjak dewasa" in the song lyrics of “Takut” by IDGITAF. Utilizing the Conceptual Metaphor Theory by Lakoff and Johnson (1980), the structural metaphors in the song's lyrics were examined through the mapping of source and target domains, as well as their image schemas. This research employs a descriptive qualitative approach. Data analysis was conducted using the distributional method and advanced techniques for immediate constituent analysis, while data collection was carried out through the observation method with note-taking techniques. The analysis revealed five structural metaphors: (1) ambisiku bergejolak, (2) antusias tak karuan, (3) mimpi yang kukejar, (4) mimpi yang terkubur, dan (5) mengorbankan waktu tidur. The image schema depicted from these metaphors is existence. The metaphor of "beranjak dewasa" represents a process filled with enthusiasm, struggle, and sacrifice. This metaphor provides a depiction for today's youth who are transitioning into their 20s, a phase where they encounter a different world where expectations do not always align with dreams or aspirations. The findings of this study affirm the song's message that every young person will inevitably go through their youth and must prepare to enter adulthood.Penelitian ini bertujuan untuk menguraikan metafora “beranjak dewasa” dalam lirik lagu “Takut” karya IDGITAF. Dengan memanfaatkan Teori Metafora Konseptual Lakoff dan Johnson (1980), ungkapan metaforis struktural dalam lirik lagu tersebut dianalisis pemetaan ranah sumber dan ranah sasarannya, begitu juga dengan skema citranya. Penelitian ini menggunakan pendekatan kualitatif deskriptif. Analisis data dilakukan dengan metode agih dan teknik lanjutan bagi unsur langsung. Sementara itu, pengumpulan data dilakukan dengan metode simak dengan dukungan teknik catat. Dari hasil analisis ditemukan lima metafora struktural, yaitu: (1) ambisiku bergejolak, (2) antusias tak karuan, (3) mimpi yang kukejar, (4) mimpi yang terkubur, dan (5) mengorbankan waktu tidur. Skema citra yang tergambar dari kelima metafora tersebut ialah keadaan (existence). Metafora “beranjak dewasa” merupakan sebuah proses yang penuh dengan semangat perjuangan dan pengorbanan. Metafora “beranjak dewasa” memberikan gambaran bagi pemuda masa kini yang akan memasuki umur 20 tahun ke atas. Pada usia tersebut mereka akan menghadapi dunia yang berbeda, semua harapan tidak selalu sesuai dengan impian atau cita-cita. Temuan penelitian ini menegaskan isi lagu bahwa setiap anak muda pasti akan melewati masa mudanya dan harus siap memasuki fase menuju dewasa.
