Microplastic contamination in the aquatic environment poses a serious threat to the survival of the ecosystem because it is persistent. This study aims to analyze the concentration of microplastics in the water column in the coastal waters of South Larompong. Sampling was carried out using the volume reduce method with the neuston net at four stations, namely Bonepute Beach, Ponnori Beach, Babana Beach and Damaci Beach. The results showed that there was microplastic contamination and found as many as 386 microplastic particles with an average concentration of 2.68 particles/m3. The results of the analysis of microplastic concentrations showed significant differences (P<0.05) between stations. The highest concentrations of microplastics are found on Bonepute Beach which is an area of aquaculture, fishing and densely populated settlements, then followed by Ponnori Beach which is a tourist area. Meanwhile, the lowest microplastic concentrations are found on Babana Beach, which is the estuary area of the Temboe River and Damaci Beach which is a nearby area. Several forms of microplastics were found, namely granules, fibers, films and fragments which were the most dominant forms. Several colors of microplastics were found, namely blue, brown, green, red, white, and black which were the most dominant colors. There are two types of polymer found, namely HDPE (High Density Polyethylene) and PVA (Polyvinyl alcohol). The conclusion of this study is that the coastal waters of South Larompong have been contaminated with microplastics so that more attention is needed regarding the handling of plastic waste, especially microplastics.

A contact lens cleaner solution should not be left in place for storage and reuse for subsequent storage. The cleaner that has been used does not have enough disinfectant power, even becomes a place of microorganism growth so the risk of infection increases. The study aims to identify the bacterial isolates of the beta hemolysis contained in the residual cleaning fluid the lens contact. The sample in this research was taken from all students in the STIKES Mandala Waluya Kendari who wear contact lenses as many as 10 people. The suspension of bacteria obtained is then planted on media BA (Blood agar) with the streak plate method. Isolates showing beta hemolysis then identified using amplification gene 16S rRNA using primers universal primers 27 F/1495 R, the results of the amplification electrophoresis with agarose of 1.5% and subsequent sequencing on the gene 16S rRNA. Based on the results of this study show the 10 isolates,
<em><em>Penggunaan handphone android (HP) oleh anak tanpa pengawasan orang tua berakibat negatif bagi perkembangan anak. Anak akan menggunakan HP secara terus menerus berakibat munculnya masalah kesehatan dan belajar. Latar belakang pekerjaan orang tua merupakan salah satu penyebab rendahnya pengawasan. Orangtua yang bekerja sebagai pedagang di pasar tradisional menghabiskan banyak waktunya di pasar. Anak setelah pulang sekolah tidak mempunyai aktivitas lain dan akhirnya menghabiskan sebagian besar waktunya bermain HP. Keadaan ini perlu diatasi dengan menyediakan aktivitas alternatif yang bisa diakses anak pedagang pasar dengan mudah. Musala di pasar menjadi tempat yang dipilih untuk menyelenggarakan kegiatan pengabdian dengan tema Musala Sekolahku. Metode pengabdian dengan pendekatan edukasi dalam bentuk mengajarkan menggunakan HP dengan baik, belajar mengaji dan bimbingan belajar dengan metode belajar sambil bermain. Anak-anak yang mengikuti kegiatan terdiri atas kurang lebih 40 orang dengan rentang usia 7-16 tahun. Anak-anak antusias mengikuti kegiatan, melalui kegiatan ini aktivitas anak-anak yang sebelumnya didominasi dengan bermain HP teralihkan dengan kegiatan edukasi berupa penggunaan HP dengan baik, belajar </em></em><em>mengaji, nonton bareng dan story telling. Namun, perilaku menggunakan HP dengan baik perlu dukungan dari orang tua. Oleh karena itu, disarankan agar tindak lanjut kegiatan pengabdian ini adalah memberikan parenting education tentang pengawasan orang tua terhadap penggunaan HP anak.</em><p><strong>Kata kunci</strong><em> </em><strong>: <em>bimbingan orang tua, tradisonal, pedagang pasar tradisional, penggunaan HP anak</em></strong></p>
