Abstract

Gold ore processing is carried out by amalgamation techniques where mercury (Hg) is used as a medium to bind gold which results in water pollution around the processing area, so it is necessary to remediate water. One way in managing mercury-contaminated water is phytoremediation of the use of water kale (ipomoea aquatica forsk) and to help the phytoremediation process, ingredients are needed that can help the growth of water kale in increasing the absorption of Hg concentrations, namely the addition of liquid NPK fertilizer. This study aims to analyze water kale without liquid NPK fertilizer, and use liquid NPK fertilizer against water kale in reducing the concentration of Hg, pH and TSS metals in water. This study used an experimental method with an experimental box (container) consisting of 4 treatments, then an Analysis of Variance (ANOVA) test of 5% and Duncan Multiple Rang Test were carried out. The results showed that liquid NPK fertilizer had an influence on reducing the concentration of Hg, pH and TSS in water. Based on the results of experiments using liquid NPK fertilizer, the best treatment results were obtained in mercury absorption by water kale and reducing Hg concentration in water, namely treatment D (contaminated water + water kale + liquid NPK fertilizer) on the 14th day, as evidenced by a decrease in Hg concentration in water by 0.56 mg / l to 0.00486 mg / l, pH 10.1 to 6.86 and TSS 1695 mg / l to 1 mg / l and an increase in nitrate levels,  Phosphate and potassium in water can accelerate absorption by water kale.

Abstract

ABSTRACT This research is motivated by the high and increasing poverty rate in Mekarsari Village. Based on the Permendes PDTT number 7 of 2021 concerning the priority use of village funds in 2022, it states that village funds are prioritized for the achievement of village SDGs, one of which is poverty reduction. Mekarsari village has not been able to reduce the poverty rate of the community, so optimization is needed in Village Fund planning. The purpose of this study was to describe how the Village Fund planning in poverty alleviation in Mekarsari Village, Cikajang District, Garut Regency, using the management organizational planning theory of Ernie Tisnawati Sule and Kurniawan Saefullah. This study uses descriptive qualitative research methods with primary data obtained through observation and interviews, as well as secondary data through the study of documents and literature. Data analysis in this study was conducted through data reduction, presentation of data, as well as the affirmation of conclusions and verification. The results obtained from this study stated that the Village Fund planning in Mekarsari Village is still not effective, especially in the factual, flexible, commitment, and comprehensive dimensions so it needs to be optimized and improved again.   Keywords: Village Fund; Planning; Poverty; Village

Abstract

Tujuan dari penelitian ini adalah; (1). Untuk mengetahui perkembangan Aset Bank Syariah di Indonesia, DPK, NPF, Jumlah Kantor Bank Syariah dan Inflasi di Indonesia Tahun 2010-2014. (2). Untuk menganalisis pengaruh DPK, NPF, Jumlah Kantor Bank Syariah, dan Inflasi terhadap Aset Bank Syariah Di Indonesia Tahun 2010-2014. Penelitian ini menggunakan alat analisis, Deskriktif untuk mengetahui perkembangan dari setiap variabel, Analisis Kuantitatif digunakan untuk menjawab permasalahan pengaruh dari DPK, NPF, Jumlah Kantor Bank Syariah dan Inflasi Terhadap Aset Bank Syariah Di Indonesia. Hipotesis dalam penelitian ini menyatakan bahwa perkembangan aset bank yang dipengaruhi oleh variabel DPK, NPF, Jumlah Kantor Bank dan Inflasi berpengaruh secara signifikan terhadap aset bank. Variabel yang terbukti berpengaruh secara signifikan terhadap aset ialah variabel dana pihak ketiga (DPK) dan inflasi yakni a < 5%. Sementara variabel NPF dan Inflasi hanya berpengaruh namun tidak secara signifikan. Bedasarkan hasil uji regresi berganda diketahui bahwa variabel yang berpengaruh paling dominan terhadap perkembangan aset bank syariah ialah variabel DPK , hal ini menunjukan bahwa bank syariah telah berhasil menjaring dana pihak ketikga (DPK) serta menunjukan kepercayaan nasabah untuk menginvestasikan dananya di bank syaraiah cukup tinggi.
