Abstract

The purpose of this research is to know the habitus of rice paddy farming under 0.5 hectares in fulfilling the family's living. This research uses qualitative methods with a case study approach. The data-sensing technique uses purposive sampling. The results of the research conducted can be known that habitat farmers Habitus with less than 0.5 hectares of land in the village of Columnayan in the effort to fulfill household, not only rely on farming activities. By carrying out other alternatives to farming activities are expected to solve the problems of living in household fulfillment.

Abstract

Penggunaan beton normal memerlukan banyak waktu dan tenaga. Maka dari itu dibuat alternatif pengganti beton normal yaitu beton Self Compacting Concrete (SCC), namun penggunaan beton SCC meningkatkan penggunaan semen yang akan melepaskan CO2 ke udara sehingga dibutuhkan senyawa tambahan untuk mengurangi kadar semen. Berdasarkan hal tersebut digunakanlah fly ash sebagai bahan tambah. Ukuran fly ash sangat kecil sehingga mampu mengurangi ruang antar agregat dan mampu meningkatkan nilai kuat tekan. Beton High Volume Fly Ash Self Compacting Concrete (HVFA-SCC) memiliki kadar fly ash lebih dari 50%. Penelitian ini akan menganalisis nilai kuat tekan, kuat tarik belah, dan modulus elastisitas akibat penambahan kadar fly ash sebesar 50%, 60%, dan 70% pada beton SCC terhadap beton normal. Hasil pengujian yang didapatkan, yaitu nilai kuat tekan beton normal dan beton dengan kadar fly ash 50%, 60%, dan 70% adalah 30,09 MPa, 29,80 MPa, 26,97 MPa, dan 21,69 MPa. Nilai modulus elastisitas yang didapatkan adalah 25100,38 MPa, 25023,94 MPa, 24139,28 MPa, dan 22354,94 MPa, dan Nilai kuat tarik belah yang didapatkan adalah 3,04 Mpa, 2,24 MPa, 1,79 MPa, dan 1,38 MPa.

Abstract

Komunitas Peduli Sungai Ujung Hilir (KPSUH) is a river community located in Pandes Village, Klaten Regency with its background was formed because it considers the environment in the region.The research aims to understand how the role of the community in transforming the socio-economy community, understanding the supporting and inhibiting factors, as well as the benefits and thoughts of the community. The subject in this qualitative study is Komunitas Peduli Sungai Ujung Hilir using the functional structural of the Talcott Parsons. Sampling is naturalistic inquiry with observations, interviews and documentation. Data validity with source triangulation. KPSUH has a work program in completing the program named Pandawa. The purpose of the community is to reduce the waste that has become an old problem, to restore and restore the function of the river to restore in propely. In this study, the communities that participated in the transformation that occurred in the Ujung Hilir River area both in terms of ecology and society. KPSUH received support from both the community and the village administration of Pandes. The barriers needed by the community are the time required and considerable energy in the process of chane, factors from outside of Pandes area and misinformation. The benefit of this community role is the transformation in the socio-economic field received by residents who can now utilize the river area for positive activities.
