Abstract

Bendungan Tukul yang berlokasi di Desa Karanggede, Kecamatan Arjosari, Kabupaten Pacitan, Jawa Timur, selama proses pengerjaan terdapat berbagai macam kendala, salah satunya adalah yang diakibatkan oleh kondisi struktur geologis yang ada di lokasi. Tanah yang mudah longsor mengakibatkan terhambatnya pekerjaan pada proyek seperti contohnya pekerjaan penggalian. Sehingga pada artikel ilmiah ini digunakan alternatif modifikasi tipe spillway pada Bendungan Tukul dari tipe pelimpah samping menjadi tipe Morning Glory, dikarenakan pelimpah tipe Morning Glory ini memiliki struktur yang terpisah dengan tanah terutama bagian inlet sehingga tidak memberikan beban pada tanah terutama di bagian tebing yang mudah longsor. Dalam perencanaan modifikasi ini terdapat analisis hidrolika yang berupa perhitungan dimensi pelimpah, konduit, dan kolam olak. Dari perhitungan hidrolika juga diketahui 3 kondisi air yang terjadi pada spillway Morning Glory yaitu kondisi 1 (Crest Control), kondisi 2 (Tube or Orifice Control), kondisi 3 (Full Pipe Flow). Untuk mencari debit banjir rancangan dipilih metode hidrograf debit banjir rancangan yang paling sesuai hasilnya dari segi keamanan yaitu metode Gama 1. Dengan menggunakan pelimpah Morning Glory debit banjir dapat tereduksi sebesar 203,20 m3/dt. Lebih efektif mereduksi banjir dibandingkan desain pelimpah sebelum dimodifikasi yaitu pelimpah jenis ogee yang hanya mampu mererduksi debit banjir sebesar 90,59 m3/dt. Penggunaan spillway Morning Glory ini diharapkan bisa menjadi rujukan dalam mengatasi permasalahan struktur geologis pada proyek bendungan kedepannya dan mampu menjadi opsi optimalisasi dalam mereduksi banjir.

Abstract

Widas Subwatershed in Nganjuk Regency is a tributary of the Brantas Subwatershed that often experiences flooding during the rainy season. The data on flooding is still in the form of numbers and tables so it needs to be mapped. The presentation of data in the form of a map is needed so that readers can analyse its distribution and help in mitigation planning against flood disasters. The purpose of this research is to analyse the level of flood hazard in the Widas Subwatershed of Nganjuk Regency and present it in the form of a map. The method used was scoring of 6 flood parameters, namely slope, land elevation, soil type, rainfall, land use, and river density, then weighting with the Analytic Hierarchy Process (AHP) method. The result of this research is that Widas Sub Watershed of Nganjuk Regency is dominated by flood hazard area of 33,375.95 Ha while the flood hazard area is 3,415.55 Ha. Flood hazard areas are found in 28 villages in Gondang, Loceret, Nganjuk, Pare, Sukomoro, and Tanjunganom sub-districts. The flood-prone areas are caused by 4 main factors: low land elevation, Alluvial soil type, residential land use, and the density of the river is very sparse.

Abstract

One of the lessons that can improve every student's skills is Project-Based Learning (PjBL). PjBL itself can help students acquire knowledge by solving real-world problems in project tasks. This learning phase can gradually increase students' motivation. At first, students will have difficulty with this, but over time they will gain experience to get used to solving different problems in each part of the project. Therefore, students' competence will continue to increase in the final phase as more and more of them put learning theory into practice. To determine to what extent the students' learning success increases through the use of PjBL in class, the use of joint project tasks in several subjects is examined. The study was conducted using Classroom Action Research (PTK) consisting of 2 cycles. The research location is at SMKN 1 Blitar with the research sample being type XII PPIB 1. The tools used are observation forms for quantitative data and interview forms for qualitative data. Observation of student learning activities is carried out during the teaching and learning process. The general project task topics covered are Software Application and Building Interior Design (APLPIG), Construction Cost Estimation (EBK), and Building Utility Construction (KUG). The observed results show that in cycle 1 the average value of student learning activities is 69.19%, while in cycle 2 the average value of student learning activities is 78. 82%. Based on the results of hypothesis testing in each subject, it was found that the average score of each student increased from cycle 1 to cycle 2. In addition, through observing 7 types of learning activities, we also found that each student increased in each subject. type of learning activities in PTK. In summary, learning activities increased when PjBL was implemented Abstrak Salah satu jenis pembelajaran yang dapat meningkatkan kemampuan individu setiap siswa adalah pembelajaran berbasis proyek (PjBL). PjBL sendiri dapat membantu siswa memperoleh pengetahuan dengan memecahkan masalah kehidupan nyata dalam  proyek. Fase pembelajaran ini memungkinkan motivasi siswa berkembang secara perlahan. Pada awalnya siswa akan mengalami kesulitan dalam mengerjakan, namun seiring berjalannya waktu, mereka akan memperoleh pengalaman dan terbiasa memecahkan masalah yang berbeda-beda di setiap bagian proyek. Pada tahap akhir keterampilan siswa akan terus meningkat karena pembelajaran teori banyak dipraktikkan. Penerapan  proyek gabungan pada beberapa mata pelajaran akan diteliti untuk mengetahui sejauh mana peningkatan aktivitas belajar siswa ketika penerapan PjBL di kelas.

Abstract

Vocational High Schools (SMKs) are educational institutions that emphasize equipping students with specific skills that can be directly applied in the workforce, aiming to reduce unemployment rates. However, unemployment in Indonesia remains significantly high among SMK graduates, which is largely attributed to the low work readiness of students. This study aims to examine the influence of practical learning and field work practical experience (PKL) on the work readiness of class XII students in the Building Design, Modeling, and Information Expertise Program (DPIB) at SMK Negeri 6 Malang, both partially and simultaneously. The research employed a quantitative approach using a saturated sampling technique, with all 89 students of class XII DPIB participating as respondents. Data collection was conducted through structured questionnaires and observations. The data were analyzed using descriptive statistics, prerequisite tests, multiple regression analysis, multiple correlation analysis, and calculations of relative and effective contributions, assisted by IBM SPSS Statistics software. The results indicate that both practical learning and field work experience have a significant and positive effect on students’ work readiness. When analyzed partially, each variable contributes differently: practical learning accounts for an effective contribution of 15.9% while field work experience contributes 48.2%. In terms of relative contribution, practical learning accounts for 24.8% and field work experience 75.2%. Collectively, these findings demonstrate that practical learning and field work experience significantly enhance the readiness of students to enter the workforce. This highlights the importance of integrating hands-on learning experiences and real-world field work into vocational education to better prepare students for professional environments and improve their employability. The study recommends that SMKs continue to strengthen practical learning curricula and provide ample field work opportunities to ensure graduates possess both the technical skills and work readiness necessary for successful employment.

Abstract

The current trend toward modern minimalist architecture in Indonesia often leads to the erosion of local values and the loss of cultural relevance in contemporary buildings. This phenomenon poses significant challenges for mixed-use building typologies such as Small Office Home Office (SOHO) spaces, particularly regarding the organization of circulation patterns and the protection of privacy between professional and domestic spheres. This study aims to evaluate the use of a detached Joglo structure as both a reception area and a privacy screen for the upper-floor residence. Through a descriptive qualitative case study method, this research analyzes design technical documents using spatial syntax, mass morphology, and user movement analysis. The analysis reveals that the integration of the standalone Joglo structure effectively creates a buffer zone that enhances spatial organization, thereby maintaining residents’ privacy without hindering office operations on the ground floor. This optimization of privacy management is achieved through contrasting vertical zoning and path engineering to minimize user cross-circulation. This research concludes that the application of neo-vernacular principles to the Joglo offers an adaptive design solution to the constraints of urban land, while maintaining a balance between cultural identity, commercial function, and residential comfort.
