Abstract

Land management is a manifestation of the society’s behaviour in utilizing the land. The objective of the research was to examine the effect of education level, income, land tenure, knowledge, and information input on the society’s behaviour in managing the area susceptible to landslide in Pekuncen sub-district, Banyumas district.   The method of this research was survey by employing questionnaire to collect field data. The variable comprised of the data of education level, income, land tenure, knowledge, and information input.. Stratified random sampling was applied to determine the samples of the research. The area susceptibility class  was considered as the strata in which each stratum consisted of 40 family heads as the respondents. The data analysis applied statistical test of multi-regression. Research area was divided into three classes of landslide susceptibility comprising of low, medium, and high class. Education level, income, land tenure, knowledge, and information input significantly influenced the society’s behaviour dealing with land management (determination co-efficiency (R²) was 69.9 %). It occurred in the area of medium susceptibility class. Information input (regression coefficient/(beta) = 0.817) was the most influential predictor of society’s behaviour in land management located in the low susceptibility class. From this research, it was expected that the description about the factors that influenced the society’s behaviour in managing the landslide-prone area would be a valuable reference in preventing landslide in those areas.

Abstract

Di daerah penelitian pada saat musim kemarau lahan persawahan dalam keadaan bero (tidak ditanami) karena kekurangan air untuk irigasi, padahal daerahnya bertopografi datar, sehingga memungkinkan untuk memanfaatkan air tanah sebagai sarana irigasi, sedang di daerah dengan topografi bergelombang banyak sumur gali yang kering. Penelitian ini bertujuan untuk mengklasifikasikan daerah penelitian menjadi satuan bentuk lahan dan mencari keterkaitannya dengan karakteristik air tanah dangkal. Metode yang digunakan yaitu interpretasi foto udara dengan didukung oleh peta topografi dan peta geologi serta cek lapangan, sehingga tersusun peta satuan bentuk lahan. Karakteristik air tanah dangkal meliputi kedalaman muka air tanah, koefisien transmisibilitas, koefisien permeabilitas, debit aliran air tanah, porositas batuan, fluktuasi muka air tanah, dan kualitas airtanah. Dari peta satuan bentuk lahan disusun peta hidromorfologi, dengan cara memasukkan data karakteristik air tanah dangkal. Hasil penelitian ini menunjukkan bahwa, kondisi geomorfologi mempunyai keterkaitan dengan karakteristik air tanah dangkal yang tercermin pada satuan bentuk lahan dan satuan hidromorfologi. Pada setiap satuan bentuk lahan mempunyai karakteristik air tanah dangkal yang berbeda-beda baik kualitas tnaupun kuantitas. Satuan bentuk lahan tanggul alam potensi air tanahnya terbesar dan kualitasnya terbaik.
