Abstract

ABSTRAKSeiring dengan meningkatnya jumlah sampah organik yang bersumber dari rumah tangga, menyebabkan semakin besarnya kebutuhan fasilitas dalam pengelolaan sampah. Perlu upaya dan strategi untuk menangani masalah ini secara tepat dan efisien. Kota Sungailiat memiliki Kelompok Swadaya Masyarakat (KSM) yang bernama KSM Srimenanti Jaya, yang peduli akan permasalahan sampah dan peningkatan kualitas lingkungan di Kota Sungailiat. Salah satu produk yang dapat dihasilkan dari pengelolaan sampah organik ini adalah pupuk kompos. Berdasarkan survei dan wawancara yang telah dilakukan, KSM Srimenanti Jaya memproduksi pupuk kompos namun memiliki permasalahan terkait kualitas pupuk kompos yang diproduksi tidak seragam/homogen. Hal ini diakibatkan oleh tidak tersedianya alat pengaduk pupuk kompos. Pengadukan pupuk kompos dilakukan secara manual menggunakan cangkul sehingga mempengaruhi homogenitas pupuk kompos yang diproduksi dan durasi proses pengadukan yang lebih lama. Oleh karena itu, perlunya penyediaan, sosialisasi dan edukasi mengenai teknologi mesin pengaduk pupuk kompos hasil olahan sampah organik bagi KSM Srimenanti Jaya sebagai metode dalam upaya peningkatan kualitas pupuk kompos yang dihasilkan. Setelah dilakukan penyediaan, sosialisasi dan edukasi teknologi mesin pengaduk kompos, terdapat peningkatan kualitas pupuk kompos yang terlihat dari volume pupuk yang seragam dan tidak ada yang menggumpal. Warna dan bau pupuk kompos organik juga seperti tanah dan teksturnya tidak terlalu basah/kering. Berbeda dengan kondisi hasil sebelum adanya penggunaan mesin pengaduk kompos. Selain itu, berdampak baik juga pada produksi pupuk kompos yang meningkat sebanyak 1 ton per bulan. Kata kunci: sampah organik; sampah rumah tangga; pupuk kompos; mesin pengaduk. ABSTRACTAlong with the increasing amount of organic waste sourced from households, causing the need for facilities in waste management is increasing. Efforts and strategies are needed to deal with this problem appropriately and efficiently. Kota Sungailiat has a Non-Governmental Organization (KSM) named KSM Srimenanti Jaya which cares about waste problems and improving environmental quality in Kota Sungailiat. One of the products that can be produced from this organic waste management is compost. Based on surveys and interviews that have been carried out, KSM Srimenanti Jaya produces compost but has problems related to the quality of the compost produced which is not uniform/homogeneous. This is due to the unavailability of a compost mixer. Compost mixing was done manually using a hoe that affects the homogeneity of the compost produced and the duration of the mixing process. Therefore, it is necessary to carry out provision, socialization and education about composting machine technology for processing organic waste for KSM Srimenanti Jaya as an effort to improve the quality of the compost produced. After providing, socializing and educating the compost mixer technology, there was an increase in the quality of the compost as seen from the uniform volume of fertilizer and no lumps. The color and smell of organic compost is also soil-like and the texture is not too wet/dry. This condition has the differences between the results before and after using a compost mixer machine. Besides that, it also has a good impact on compost production which increases by 1 ton per month. Keywords: organic waste; household waste; compost; compost mixer machine.

Abstract

In this study, green synthesis of silver nanoparticles via Cratoxylum glaucum leaf extracts loaded with polyvinyl alcohol and its bacterial activity were tested. Nanosilver from ‘Pucuk Idat’ leaves has a non-uniform size and tends to agglomerate, making the nanoparticle size unstable and challenging to apply further. Therefore, so that nanoparticles do not aggregate, efforts are made to add stabilizers. Polyvinyl alcohol (PVA) is a polymer that can be used as a stabilizer because it can prevent unwanted aggregation and oxidation processes. UV-Vis analysis results show that PVA as a stabilizer can avoid an increase in wavelength shift. Based on the results of this XRD analysis, it can be concluded that in this research sample, the silver nanoparticle is formed with a cubic crystal system, and it can be observed that the smallest average particle size is in the 0.75% Ag/PVA sample of 10.32 nm. Furthermore, based on the antibacterial test against E. coli and S. aureus, it can be explained that the 0.75% PVA-modified nanosilver sample showed weak to medium antibacterial activity..

Abstract

The distribution and enrichment of heavy metals in sediments will affect the life of the organisms that lives in it. The purpose of this study is to explain the enrichment and contamination levels of heavy metals Cu and Pb in bulk sediments in the northern and southern parts of Bangka Island. This research was conducted in August - September 2019, using a purposive sampling method. Heavy metal analysis using the Inductively Coupled Plasma - Optical Emission Spectroscopy (ICP-OES) instrument. The results showed that the concentration of the heavy metal Pb in the sediment bulk of northern Bangka Island (Kelabat Bay) was higher than that of South Bangka Island. The concentration of heavy metal Cu at 8 (eight) sites is still below the quality standard (18.7 mg.kg-1) even if the heavy metal Pb at stations 3, 4, and 5 in the waters of the northern half of Bangka Island (Kelabat Bay) is reported to have exceeded the quality standard limit (30.2 mg.kg-1). The highest level of enrichment of heavy metal Pb occurs at station 4 with a value of EF_62.88, and is categorized as very high enrichment and a contamination factor (CF) value of 2.24 (medium category). This condition is due to station 4 being located in Kelabat Bay (semi-enclosed area) with unstable water conditions due to the influence of many activities. The results of this study can be used as input for local governments for the management of water areas on Bangka Island.
