Abstract

Ibu rumah tangga merupakan potensi tersendiri untuk pengembangan ekonomi dan nutrisi keluarga. Ikan lele dumbo memiliki rasa gurih dan telah menjadi bagian dari menu masyarakat Riau. Di sisi lain, ikan ini relatif mudah dibudidayakan, tahan terhadap lingkungan ekstrim bahkan di daerah sempit tanpa perlu air mengalir. Kegiatan ini bertujuan membina ibu rumah tangga untuk memelihara ikan lele dumbo di dalam drum, membuat pakan ikan lele sendiri dan memproses sebagian dari hasil panen mereka. Program ini diadakan di Kampung Minas Barat, Kabupaten Siak, Riau dengan menggunakan metode demonstrasi langsung. Para peserta diajari cara membuat pakan ikan, budidaya ikan lele dan kegiatan pasca panen. Dimulai dari pembentukan kelompok dan pengangkatan ketua dan sekretaris. Dilanjutkan dengan kegiatan tatap muka, praktik langsung membuat pakan ikan, persiapan wadah tumbuh, penebaran benih ikan dan pemeliharaan. Setiap peserta diberikan 1 unit drum bervolume 200 L, 300 ekor bibit ikan dan sejumlah pakan ikan lele yang mereka produksi sendiri. Satu unit mesin pembuat pelet diserahkan kepada kelompok ini. Kegiatan pemantauan dilakukan terus menerus dengan setiap 2-3 minggu, baik melalui kunjungan langsung atau melalui telepon. Peserta binaan terlihat serius, antusias dan rajin dalam menjalankan program ini. Sampai di akhir kegiatan ikan sudah mulai dipanen dan dikonsumsi oleh anggota keluarga sendiri. Dilihat dari perspektif penguatan ekonomi keluarga dan peningkatan gizi rumah tangga, kegiatan ini dianggap cukup baik dan diharapkan ditiru oleh anggota masyarakat lainnya.

Abstract

This research was conducted in March-April 2019 in the waters of Tanjung Balai Asahan, North Sumatra Province. Aim to determine the particle size of sediments, determine the abundance and distribution patterns of kerang darah (A. granosa), and analyze the effect of particle size of sediments and organic matter on the abundance of kerang darah (A. granosa). Sediment and kerang darah (A. granosa) samples were taken using a grab sampler from 4 stations, each station consists of 5 sampling points. The results showed that the environmental conditions of Tanjung Balai Asahan waters were still able to support the life of kerang darah (A. granosa). The type of sediment in these waters is dominated by sandy mud. The average diameter of sediments (Mz) 3-7.7 Ø with classification as very fine sand-very fine silt. The highest average content of organic sediment is found at station 2 (13.70%) which is located around the mangrove forest which is included in the classification of medium organic matter. The highest average value of kerang darah (A. granosa) abundance is at station 4 (54 ind/m2), with a clustered distribution pattern at all stations. The relationship between sediment characteristics and abundance of kerang darah (A. granosa) in Tanjung Balai Asahan waters is classified as a strong relationship with a determination coefficient (R2) of 0.529, this means that the size of sediment particles 52.9% affects the abundance of kerang darah (A. granosa) throughout the station while the remaining 41.7% are influenced by other factors not examined. The relationship of the content of organic matter with the abundance of kerang darah (A. granosa) is classified as a weak relationship, with a coefficient of determination (R2) of 0.004, meaning that the content of 0.4% sediment affects the abundance of kerang darah (A. granosa) throughout the temporary station 99.6% is influenced by other factors not examine.

Abstract

Linear alkylbenzene sulfonate (LAS) is the main component of dispersants that function as cleaners of various materials. The increasing use of LAS causes this compound to dominantly pollute coastal waters. Phytoremediation is the most environmentally safe alternative to physical and chemical methods. One of the potential plants as a phytoremediator is Rhizophora mucronata. This research is an experiment as an application of LAS pollutant control by R.mucronata plants in waters. After acclimatization and preliminary tests, the implementation of LAS phytoremediation tests by R. mucronata plants in seawater media was carried out at concentrations of A1: 25 mg/L, A2: 100 mg/L, A3: 175 mg/L, A4: 250 mg/L, and A5: 325 mg/L and control (Control without plants) as a simulation of the presence of pollutants in coastal waters. The method used was a completely randomized design (CRD) with one treatment and 3 replications. The reduction of LAS concentration in the test media and its effect on R.mucronata leaf chlorophyll and dissolved oxygen were analyzed at week 2 to week 4. The analysis results showed that LAS compounds could be reduced to 91.48% at week 2 and 97.40% at week 4. Plant Water quality parameters (dissolved oxygen, temperature and pH) were measured daily. Based on the study results, LAS can be reduced by R.mucronata plants 87-90.4% in week 2 and 95.1-97.4% in week 4. LAS exclusion by plants had a significant impact on the reduction of leaf chlorophyll content until week 4. LAS reduction by R.mucronata in the media can increase dissolved oxygen content as an indication of improved water quality. R.mucronata plants can be used as an alternative to control LAS pollution in waters
