Abstract

Beton berpori pada pembangunan infrastruktur jalan sangat jarang digunakan dan memiliki keunikan tersendiri. Pembangunan jalan lingkungan pada umumnya menggunakan pekerasan beton. Ada jenis beton dikenal dengan beton berpori. Dengan adanya pori-pori pada beton, maka dapat digunakan untuk menyerap limpasan permukaan dan sekaligus menambah cadangan air tanah, serta mencegah terjadinya banjir. Perkerasan jalan dengan beton berpori ini merupakan salah satu alternatif perkerasan yang diharapkan dapat mengurangi permasalahan lingkungan yang ada. Salah satu caranya dengan menggunakan limbah pabrik yaitu fly ash. Fly ash dapat digunakan sebagai bahan tambah pada semen untuk beton, karena memiliki sifat pozzolan yang dapat meningkatkan kekuatan dan durabilitas beton. Oleh karena itu, pada penelitian ini dilakukan menggunakan beton pori dengan fly ash sebagai limbah pabrik yang terbukti dapat meningkatkan kekuatan pada beton. Maka salah satu cara agar material hasil produksi sampingan tersebut tidak mencemarkan lingkungan adalah dengan menggunakan material tersebut sebagai bahan penambah sebagian semen. Penelitian ini bertujuan untuk mengetahui nilai kuat tekan dan porositas beton porous dengan penggunaan fly ash serta komposisi campuran maksimum dan minimum yang diperoleh pada campuran fly ash dengan varasi 0% 15%,25%, dan 35%, dan menggunakan metode dari [1] American Concrete Institute 522 R-10. Berdasarkan hasil penelitian menunjukan bahwa variasi campuran fly ash 25% merupakan hasil yang optimum dimana hasil kuat tekan yang diperoleh sebesar 10,333 MPa dengan porositas dengan campuran fly ash Minimum sebesar 29.3%. Dari hasil penelitian ini dapat disimpulkan pada variasi 0%, nilai kuat tekannya 9,483 MPa dan porositasnya 36.1%, hasil variasi Fly Ash 15% nilai kuat tekannya 8.776 MPa, porositasnya 29.3%, hasil variasi Fly Ash 25% nilai kuat tekannya 10,333 MPa dan porositasnya 31.2%. dan nilai variasi Fly Ash 35% nilai kuat tekannya 9,766 MPa, dan porositasnya 33.2%.

Abstract

Program IPDMIP (Integrated Participatory Developmnet Program) yang dilaksanakan oleh Kabupaten Pasaman dinilai sukses oleh pemerintah pusat. Tujuh daerah irigasi yang mendapatkan bantuan dana dari Program IPDMIP mengalami peningkatan indeks kinerja sistem irigasi dari tahun 2020 sampai tahun 2022. Akan tetapi, berdasarkan Permen PUPR No.12/PRT/Tahun2015 peningkatan kinerja irigasi dari enam daerah irigasi mendapatkan kategori kinerja kurang baik dan satu daerah irigasi dengan kategori kinerja baik. Daerah irigasi kategori kinerja baik (DI Batang Petok) dan daerah irigasi kategori kinerja kurang baik dengan nilai terendah (DI Simpang Dingin Barilas) menjadi perhatian penulis dalam penelitian evaluasi kinerja irigasi pada program IPDMIP berbasis EPAKSI di Kabupaten Pasaman ini. Dalam penelitian ini menggunakan pendekatan kombinasi (mix mehods), dimana evaluasi kinerja irigasi berbasis EPAKSI selanjutnya dilakukan wawancara dan dilakukan analisis SWOT untuk mendapatkan strategi untuk tahun selanjutnya. Dalam menentukan sumber data digunakan metode purposive sampling. Hasil observasi lapangan didapatkan peningkatan tertinggi dari DI Batang Petok adalah pada komponen organisasi personalia dan sarana penunjang yang saling berkaitan, sedangkan hasil observasi lapangan rendahnya peningkatan DI Simpang Dingin Barilas terlihat pada bangunan intake bendung dimana terjadi penurunan debit air masuk ke saluran karena banyaknya sedimen yang menumpuk pada pintu bendung tersebut.

Abstract

One important step in an effort to meet the housing needs of the community is the construction of housing and settlements whose main goal is to prepare prosperous housing with adequate and affordable infrastructure, facilities and utilities. This study aims to be able to see the extent of the effectiveness of the implementation of the self-help housing stimulant assistance program which refers to technical guidelines. The analysis uses a descriptive qualitative approach, by taking assessment indicators about habitable houses based on technical instructions for the implementation of activities, After that, questionnaires were distributed to 26 houses receiving aid, 14 houses in Nagari Surian and 12 houses in Nagari Lolo Sampling take with using a Likert Scale using a Scale of 5, starting from Very Unsuitable (STS) to Very Suitable (SS), so that the implementation process can run optimally to be able to see threats that occur and also see opportunities to be able to optimize the implementation process is carried out also analysis using the SWOT MethodThe results of the study show that the application of assessment indicators taken from technical implementation guidelines falls into the "appropriate" category where for Nagari Surian it is at 4.14 out of a maximum scale of 5 and for Nagari Lolo it is at 4.16. However, in the aspect of assessing access to adequate tap water in Nagari Lolo is included in the "Quite Appropriate" category, this is because not all houses can be reached by water from Water Suplly Company, so people still rely on tap water from residents' wells or spring sources. The results of the analysis for the value of self-help are also very good because the value of community self-help is 83% - 94%, The role of the facilitator is also very influential on the implementation of the self help housing stimulant assistant program because it can help the community to understand the purpose of the BSPS program itself.

Abstract

Background: Effective waste management is pivotal for establishing eco-friendly educational environments, guided by global sustainability standards. However, many institutions face challenges in aligning their practices with these environmental benchmarks. Knowledge Gap: Research often highlights the necessity of holistic waste strategies but lacks specific assessments of waste management within the context of Green Campus initiatives, especially in vocational education settings. Aims: This study aims to evaluate current waste management practices at a technical polytechnic, assessing their effectiveness and compliance with established green standards. Results: The evaluation reveals that the institution's waste management initiatives are significantly lacking, with a total score of only 75 out of a possible 1800 points. The polytechnic performs poorly in recycling and processing various waste types, although there is modest progress in reducing paper and plastic use. Novelty: This research introduces a novel application of global sustainability standards to assess waste management practices at a vocational higher education institution, highlighting specific areas of inefficiency and their broader implications. Implications: The findings emphasize the critical need for comprehensive recycling programs, improved waste segregation, and increased community involvement in sustainability efforts. These improvements are crucial for both environmental benefits and enhancing the institution's standing in global educational rankings that prioritize sustainability. Highlights: Enhance Recycling: Implement robust recycling programs to meet global sustainability standards. Improve Segregation: Develop better waste segregation and processing practices. Boost Community Involvement: Engage the campus community actively in sustainability efforts. Keywords: Waste Management, Green Campus, Recycling, Environmental Education, UI GreenMetric

Abstract

Proyek konstruksi merupakan proyek yang berisiko dengan kompleksitas tinggi, menimbulkan ketidakpastian, dan pada akhirnya menimbulkan berbagai risiko. Tidak teridentifikasi dan tertanganinya faktor - faktor risiko dalam pelaksanaan proyek tersebut dapat mengakibatkan kendala dalam pencapaian tujuan proyek dibidang waktu (time), biaya (cost) dan kualitas (quality). Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor risiko penyebab keterlambatan yang dihadapi oleh pelaku konstruksi gedung di Kabupaten Sijunjung, melakukan penilaian tingkat risiko dan merencanakan respon risiko. Metode yang digunakan adalah metode kuantitatif dengan identifikasi risiko yang dilakukan adalah melakukan studi literatur, penilaian frekuensi/probabilitas risiko dan penilaian dampak risiko menggunakan Severity Index dan Probability Impact Matrix. Sedangkan untuk merencanakan respon risiko dilakukan dengan melakukan studi literatur dan meminta pendapat ahli. Dari hasil analisis diperoleh kesimpulan bahwa terdapat 3 risiko dengan kategori risiko tinggi yaitu: 1. ketersediaan keuangan selama pelaksanaan/ penyediaan aliran kas yang cukup; 2. Tidak adanya dukungan keuangan dari bank untuk penambahan modal kerja; dan 3. Gangguan keamanan di lokasi proyek. Rencana respon yang didapat adalah dengan strategi mengurangi (mitigate), menghindari (avoid) dan mengalihkan (transfer) dan terdapat 7 rencana tindakan yang dapat dilakukan untuk menghindari keterlambatan sebagai dampak negatif dari risiko.
