Abstract

Pembangunan perumahan di Kabupaten Karanganyar semakin meningkat, hal ini dapat dilihat dari jumlah permohonan ijin pembanguanan perumahan yang diajukan oleh Perusahaan Pengembang Perumahan ke DPUPR Kabupaten Karanganyar, baik untuk perumahan komersil maupun perumahan subsidi. Meningkatnya pembangunan perumahan juga mengakibatkan permintaan material bangunan semakin banyak, tak terkecuali pada material penutup atap. Perusahaan yang bergerak di bidang industri bahan material penutup atap, menawarkan berbagai macam inovasi pada produknya untuk memperbaiki kualitas dari berbagai jenis produk material yang sudah ada. Terdapat berbagai macam jenis bahan pembuat material penutup atap pada saat ini. Setiap material penutup atap itupun mempunyai kelebihan dan kekurangan. Maka perlu dinilai, material penutup jenis apa yang diperlukan sesuai keinginan steakholder. Tujuan penelitian ini adalah untuk mengetahui material penutup atap yang sesuai dengan keinginan steakholder di Kabupaten Karanganyar. Penelitian dilakukan pada beberapa jenis penutup atap yang beredar dipasaran dan berpotensi digunakan sebagai penutup atap perumahan. Perhitungan pemilihan penutup atap menggunakan metode AHP. Kriteria yang digunakan dalam metode AHP ini adalah triple constraint, yaitu biaya, waktu dan mutu. Setelah melalui proses mendapatkan data primer dan sekunder serta perhitungan analisis dengan microsoft excell, selanjutnya didapatkan hasil prosentase bobot kriteria sebagai berikut, biaya 33,02%, waktu 24,45% dan mutu 42,53%. Hasil penelitian menyimpulkan bahwa dengan metode AHP untuk pemilihan material penutup atap, dihasilkan urutan sebagai berikut yaitu penutup atap dari Genteng metal, Genteng Keramik, Genteng Tanah Liat, Genteng Beton, Asbes dan Genteng Aspal. Cara ini mengkombinasi pedoman triple constraint berdasarkan tingkat kepentingan, sehingga hasil urutan pemmilihan lebih obyektif.

Abstract

Paving block adalah merupakan salah satu elemen bahan bangunan yang dibuat dari campuran semen portland atau sejenisnya, agregat, air dengan atau tambahan lainnya yang tidak mengurangi mutu bata beton tersebut (SNI-03-0691-1996). Beberapa penelitian telah mengeksplorasi penggunaan fly ash. Fly ash merupakan limbah hasil pembakaran batu bara pada tungku pembangkit listrik tenaga uap yang berbentuk halus, bundar dan bersifat pozolanik (SNI 03-6414-2002). Beberapa penelitian terdahulu terkait paving block dan fly ash telah membuat inovasi dengan tujuan mengetahui besarnya pengaruh penambahan fly ash terhadap sifat mekanis paving block (kuat tekan) dan persentase penambahan fly ash yang terbaik untuk campuran paving block. Metode penelitian yang digunakan berupa eksperimen dengan menambahkan fly ash sebagai bahan campuran pembuatan paving block. Dari hasil literature review beberapa artikel dapat disimpulkan bahwa fly ash dapat meningkatkan kuat tekan paving block pada variasi tertentu daripada paving block tanpa fly ash, akan tetapi jika penggunaan fly ash yang berlebihan dapat juga mengurangi mutu dari paving block. Variasi yang mempunyai kuat tekan optimal paling tinggi adalah pada variasi 1Pc:1Ps dengan penambahan fly ash 10%, kuat tekan rata-rata 34,80 MPa sehingga masuk dalam kategori mutu B.

Abstract

The banks of the Gajahwong River in Yogyakarta City are part of the slum area based on a decree from the Mayor of Yogyakarta in 2016. Various Community-Based Environmental Empowerment Programs (PLPBK) have been implemented until 2022. For this reason, it is necessary to carry out a qualitative evaluation of the success of its implementation in overcoming slums in a sustainable manner, including involvement the parties in it. The condition of the Warungboto Slum Area is a mild slum with an average sectoral slum of 23.7% in certain RTs. The existence of the Kotaku program with the handling of increasing settlements in terms of road infrastructure, drainage, infiltration wells has had an impact on the non-slum parameter score but the handling of house buildings and riverbank inspection roads is still problematic. Thus the involvement and commitment of all parties, the government, local communities as well as NGOs and universities need to be strengthened so that slum reduction can be optimally realized.

Abstract

The Majapahit Traditional Market is a market that was initiated by residents as a local populist economy urban in the Kaliurang tourist area of ​​Mount Merapi, Sleman, Yogyakarta. The concept of a market with tourist content packaged as a money transaction model is replaced by “dono” like ancient times to attract visitors. The area whose land belongs to the residents with local wooden and bamboo turban buildings is increasingly becoming a feature of the market appearance. As a result of the COVID-19 pandemic with the PPKM Government Regulation, the market which has only been running for 9 months since November 2019 has made the abandoned market abandoned by traders and managers. This condition has attracted the attention of Civil Engineering students, FT UCY, to contribute and first help to fix the market through the Thematic Community Service Program. The purpose of the activity is to fix market support facilities and increase the motivation of managers to maintain the market. The method used is a site survey, analyzing needs and carrying out physical activities at the market location. By knowing that some of the facilities were damaged and had not been equipped, then through coordination between students, field supervisors and market managers, activities in the form of repainting the kiosk, stage, sitting room, spot shelfi and gate. The addition of the required facilities in the form of a classic model of bamboo trash can, a classic model of hand washing, an information board. For joint maintenance, student work, field supervisors and traders are carried out. The need for facilities that still need to be continued as a service program for the provision of clean water pipelines, water towers and faucets.
