Abstract

 As a source of minerals, water must be continuously maintained, including in term of its quality. Meanwhile, swamps are wetlands that have the potential to experience a decline in water quality. The presence of river borders in swamps has been known to maintain their water quality. Vegetation cover of the river border is established through restoration activities in which it is expected, directly and indirectly, to improve water quality. This study aimed to investigate the water quality in swamp using the Water Quality Index (WQI). Surveys were carried out and samples were collected to determine the effect of restoration on river border in swamps. Samples were collected severally, namely prior to restoration (T0), first year (T1), third year (T3) and fourth year (T4) after restoration. The parameters for water quality of T0 and T1 include pH, DO, BOD, TDS, turbidity and nitrate, while for T3 and T4 include: pH, DO, BOD, TDS, temperature, phosphate, E. coli and nitrate. The findings indicated that the WQI of the swamp prior to restoration was greater than that at the first year of restoration due to the process of land clearing. Meanwhile, the WQI at the third year has improved compared to before the restoration and land clearing phase. It suggests that the presence of vegetation on river border is able to improve the water quality. At the fourth year, a fire in the upstream reached the area adjacent to the study site. It led to a decline in surface water quality and affected the water quality index. Furthermore, the abundance of aquatic biota was indicated by two taxa of zooplankton in the third year of restoration while none of them was identified in the fourth year. In overall, restoration activities on the river border improve the quality of water in swamps in a sustainable manner.

Abstract

Population pressure on agricultural land is one of  the important parameters to determine the level of  watershed environment quality. High population pressure on agricultural land in a watershed can lead to land degradation and watershed ecosystems damage. The purpose of  research is to calculate and determine the level of  population pressure on agricultural land in the sub watershed and in each district in the sub watershed by using Geographic Information System (GIS). Population pressure on agricultural land is calculated by using Soemarwoto's formula (1985). The classification of  population pressure on agricultural land is based on the Decree of  the  Directorate General of  Land Rehabilitation and Social Forestry (RLPS,) Ministry of  Forestry of  Indonesia No. P.04/VSET/2009. The research was conducted in Keduang sub-watershed which is part of  water chatchment area of  Gajah Mungkur Reservoir in Wonogiri District, Central Java. The results showed that population pressure on agricultural land in Keduang Sub-watershed is categorized as “bad” with the value of  28.978,16. Girimarto, Jatipurno, Jatiroto, Jatisrono and Sidoharjo districts are categorized as “medium”, while Jatiyoso, Kismantoro, Ngadirojo, Nguntoronadi, Purwantoro, Slogohimo and Tirtomoyo districts are categorized as “bad” with the value more than 2.

Abstract

ABSTRACTSoil Bioengineering technique is a soil and water conservation technology innovation for landslide mitigation. The success of technological innovation is influenced by the perception and characteristic of the user community. This study aimed to determine the characteristics of farmers as potential users and their perceptions that were measured based on an assessment of characteristics of technology innovation. This study used a qualitative approach combined with the support of qualitative data quantification. Data collected consist of primary data and secondary data. Primary data include the characteristics of respondents and their perceptions of Soil Bioengineering innovation in the form of assessment variables consisting of certain indicators which are then measured using a Likert scale. The characteristics of farmers prospective users of Soil Bioengineering techniques are: 1) productive age, 2) lack of education (junior high school), 3) narrow land ownership (0.1 to 0.3 hectares), 4) the commodity planted is salak, 5) experience as farming (16 - 20 years) and, 6) medium/ middle income levels (3- 4.9 million rupiah per month). Farmer's perceptions are generally positive to Soil Bioengineering. Positive perception techniques if it was measured based on: 1) relative advantage, 2) compatibility, 3) simplicity, 4) trialability and 5) observability.Keywords: perception; community; innovation; technique; soil bioengineering; mitigation;landslide ABSTRAKTeknik Soil Bioengineering merupakan inovasi teknologi konservasi tanah dan air untuk mitigasi longsor. Keberhasilan inovasi teknologi ini dipengaruhi oleh persepsi dan karakteristik masyarakat pengguna. Penelitian ini bertujuan untuk mengetahui karakteristik petani sebagai calon pengguna dan persepsinya yang diukur berdasarkan penilaian terhadap karakteristik inovasi teknik Soil bioengineering. Penelitian ini menggunakan pendekatan kualitatif yang dipadukan dukungan kuantifikasi data kualitatif. Data yang dikumpulkan berupa data primer dan data sekunder. Data primer meliputi karakteristik responden dan persepsinya terhadap inovasi Soil Bioengineering yang berupa variabel-variabel penilaian yang terdiri dari indikator-indikator tertentu yang kemudian diukur dengan menggunakan skala Likert. Karakteristik petani calon pengguna Teknik Soil Bioengineering adalah: 1) berusia produktif, 2) berpendidikan rendah (SMP), 3) luas kepemilikan lahan yang sempit (0,1 sampai 0,29 hektar), 4) komoditi yang ditanam adalah salak, 5) Berpengalaman sebagai bertani (16 – 20 tahun) dan, 6) tingkat pendapatan yang sedang/ menengah (3- 4,9 juta rupiah per bulan). Persepsi petani umumnya positif terhadap teknik Soil Bioengineering. Mempunyai persepsi positif bila diukur berdasarkan: 1) keuntungan relatif, 2) kesesuaian, 3) kesederhanaan, 4) ketercobaan/ dapat dicoba dan 5) keteramatan/ dapat diamati.Kata kunci: persepsi; masyarakat; inovasi; teknik; soil bioengineering; mitigasi; longsor
