Abstract

AbstrakSemakin banyaknya pemukiman yang dibangun di bantaran sungai di Yogyakarta membuat sungai tercemar limbah rumah tangga. Penelitian ini bertujuan untuk mengetahui efektivitas tanaman eceng gondok (Eichhornia crassipes), genjer (Limnocharis flava), dan semanggi (Marsilea crenata) sebagai fitoremediator dengan wetland system dalam pengolahan air limbah domestik. Tahap pelaksanaan penelitian fitoremediasi diawali dengan pengukuran parameter air limbah yaitu pH, suhu, DO, BOD, dan TDS. Setelah itu, dilakukan aklimatisasi tanaman pada reaktor yang berisi air dan wetland selama 1 minggu. Terdapat empat perlakuan (P1, P2, P3, dan P4) yang digunakan, yaitu P1: air limbah + wetland (sebagai kontrol), P2: air limbah + wetland + 1 eceng gondok, P3: air limbah + wetland + 1 genjer, P4: air limbah + wetland + 1 semanggi. Terdapat 2x pengulangan selama masa retensi 12 hari, 2 variasi pengenceran yaitu 10x dan 100x. Hasil penelitian menunjukkan bahwa tanaman genjer mampu meningkatkan kadar DO sebesar 50% dan menurunkan kadar BOD sebesar 78%, serta tanaman semanggi mampu menurunkan kadar TDS sebesar 41,4%. Angka ini mencerminkan bahwa penggunaan tanaman-tanaman tersebut memiliki potensi besar dalam membantu pemurnian air.Abstract The increasing number of settlements built along the river banks in Yogyakarta resulted in household waste entering the river. This study aims at determining the effectiveness of water hyacinth (Eichhornia crassipes), genjer (Limnocharis flava), and clover (Marsilea crenata) as phytoremediators, in a wetland system. Firstly, wastewater parameters such as pH, temperature, DO, BOD, and TDS are measured. After that, plants were acclimatized in the reactors containing water and substrate derived from a wetland for 7 days. There were four treatments applied in this research (P1, P2, P3, and P4), P1: wastewater + wetland (as control), P2: wastewater + wetland + 1 water hyacinth, P3: wastewater + wetland + 1 genjer, P4: wetland water + wetland + 1 clover. Each treatment was replicated twice during the 12 days retention period, and 2 variations of dilution of 10x and 100x. The results indicated that genjer plant was capable of increasing the DO level by 50% and lowering the BOD level by 78%, and the clover plant was able to decrease the TDS level by 41.4%. Those results reveal that the use of the plants has huge potential in helping water purification.

Abstract

Research on riparian vegetation and ecosystem services perception is essential to encourage community involvement in river area management. Therefore, this study aims to examine the composition of riparian vegetation along the upper Gajahwong River and assess local community perceptions of the ecosystem services provided by riparian biodiversity. Vegetation composition was studied through a floristic survey using plots placed along transects at three locations; Hargobinangun, Sardonoharjo, and Minomartani. Community perception was assessed through a survey of 60 randomly selected residents from the three villages studied. Data analysis involved calculating species richness, and species diversity, and analyzing community perceptions based on response percentages. The study identified more than 70 plant species at each site, with a very high diversity index (>4). Species with high Importance Value (IV) included Ficus racemosa (3.11), Dieffenbachia seguine (4.40), and Acalypha indica (3.59). Dominant plant families included Araceae, Fabaceae, and Moraceae, which provide essential provisioning and regulating ecosystem functions. Regarding community perception, the study found that residents recognized ecosystem functions, including provisioning services, regulating services, and socio-cultural services. Their understanding of ecosystem services was influenced by cultural values, particularly Javanese traditions emphasizing the importance of nature conservation.
