Abstract

ABSTRAK Perkembangan teknologi dan sistem informasi yang semakin pesat membuat informasi dapat diakses secara luas dan mudah. Perkembangan teknologi dapat dimanfaatkan sebagai media pemasaran secara online. Kota Samarinda memiliki kawasan industri rumahan yang memproduksi kain tenun, yaitu Kampung Tenun. Kampung Tenun merupakan usaha industri kain tenun yang telah diwariskan secara turun temurun agar industri tersebut dapat terus dilestarika. Salah satu produk yang dihasilkan dari industri kain tenun adalah Kain Sarung Samarinda dan Kain Tajong Samarinda, yang dikreasikan menjadi peci, tas, sepatu, dan properti tari-tarian untuk meningkatkan harga jualnya. Selain dijadikan sebagai warisan budaya, kegiatan industri kain tenun di Kampung Tenun juga merupakan atraksi wisata budaya di Kota Samarinda. Pada tahun 2015, PT Telekomunikasi Indonesia Tbk (Telkom) memberikan program pengembangan UMKM dengan bantuan teknologi digital guna memperluas pemasaran dengan memjual produk secara online (Indotelko.com, 2015). Namun program tersebut belum dapat diimplementasikan secara optimal. Tujuan dari kegiaatan pengabdian ini adalah dapat meningkatkan perekonomian melalui pelatihan penggunaan e-commerce pada UMKM pengarajin tenun di Kampung Tenun, Kota Samarinda. Metode yang digunakan dalam pengabian ini adalah memberikan pelatihan dan sosialisasi penggunaan e commerce. Hasil yang diperoleh adalah masyarakat mengetahui mekanisme pejualan secara online melalui media Bukalapak. Kata Kunci:  Kampung Tenun, E Commerce, Samarinda

Abstract

Groundwater well is the alternative well providing water source in the city of Balikpapan, especially in its sub-district of Karang Joang, North Balikpapan, where the location has not been fully integrated with PDAM water pipes. Normally, the groundwater has minerals including iron (Fe). For the drinking water, the concentration standard of Fe follows the national law of Permenkes No. 493/Menkes/Per/IV/2010 which is 0,3 mg/L as the threshold. Oil palm frond is an organic matter that is found easily in East Kalimantan, containing high levels of lignin and cellulose which used to produce activated carbon. The activated carbon was evaluated with five variant doses of 5; 10; 15; 20; and 25 g/L over groundwater and the contact time of 30; 45; 60; 75; and 90 minutes. The time contact was measured by the rotation of the stirrer with the speed of 100 rpm. The results showed the optimum time contact of 30 minutes with the adsorbent dose of 5 g/L with the elimination efficiency of 99,56%. The time contact and the adsorbent dose variants have insignificant effect because of the least time contact as well as the least dose are the optimal condition in decreasing Fe

Abstract

Microplastics (MPs) significantly damage the environment and human health, leading to a growing global concern. MPs have been detected not only in the natural environment but also in the drinking water treatment process. One of the configurations of the drinking water treatment unit is filtration. Only a few research studies have been published on microplastic removal in the water system. This study was conducted to determine the performance of a rapid sand filter (RSF) in removing microplastics in water with a variation in the effective size (ES) of silica sand and microplastic size. In this study, microplastics are artificially made with size variations of < 400 μm and >400 μm. The filtering uses two variations in the adequate size (ES) of silica sand, namely 0.4 mm and 0.7 mm. At the same time, anthracite is only a control variable with ES = 0.69 with a flow speed of 4 m / h and an observation time of 30, 60, 90, and 120 minutes. The results show that the filter media ES 0.4 has the highest efficiency values of 91.30% for the microplastic size MPs <400 µm and 95.80 % for the larger microplastic >400 µm. In addition, the average percentage removal of ES 0.7 mm was 77.24 % for the size of MPs <400 µm and 95.77% for the size of Mps >400 µm. Gaining insight into the mechanisms involved in removing microplastics from drinking water is essential for developing more effective techniques for eliminating them.
