Abstract

The research on microplastics in urban drainage is becoming a concern. In the drainage of Bandar Lampung city, four different anthropogenic activities were investigated: road runoff, industrial activity, public place, and housing area. This study investigated the abundance, characteristics and distribution of microplastics (MPs) through drainage systems in dry weather. A total of sixteen drainage water samples were collected using grab sampling with a horizontal water sampler. Under microscope observation combined with a needle test, the average abundance of MPs was found 3.97±3.4 particles/L, with fibers as the dominant type of MPs. The order of MPs' abundance was industrial area > public area > transportation area > housing area. However, this number of MPs tends to be lower compared to other reported studies. The size of MPs mostly ranged from 500 - 1500 µm (36%). The color of MPs was amply diverse, with blue being in the dominant proportion (43%). Other studies also reported similar findings regarding the type and size range. Through Raman spectroscopy, the identification of polymer types indicated the presence of polyethylene terephthalate. From the correlation analysis, it was found that there was a positive correlation between the abundance of MPs and flow rate discharge, though with a low relationship (r=0.46). This result can be influenced by several factors such as the effects of multiple land use types and pollution sources. The significance of this research lies in its contribution to understanding the extent of microplastic pollution and its potential environmental impact on the Lampung water body.

Abstract

Self concept is what someone believe about his/her own self that influences thought, feeling, and behavior. It is believed that bibliotherapy could be used to enhance self concept. This research was intended to find out the effect of bibliotherapy on adolescence self-concept. Subjects were college students (N = 41) with “average” to “negative” self-concepts. Through a random assignment these subjects were divided into 3 groups, i.e. the bibliotherapy and sharing group and the bibliotherapy group, as the experimental groups, and the control group. The result using ANOVA test shows significant differences of self-concept in the pre- and posttests (p = 0.017 < 0.05). A posthoc test reveals that the control group shows a significant difference, while no significant difference exist between the first and second experimental groups. It means that bibliotherapy may influence the self concept improvement which is done by giving sharing or without sharing. Konsep diri adalah apa yang diyakini seseorang mengenai dirinya hingga memengaruhi pikiran, perasaan, dan tingkah laku. Salah satu pendekatan dalam meningkatkan konsep diri adalah bibliotherapy, yaitu dengan memberikan bacaan yang dapat mengembangkan konsep diri individu. Penelitian ini bertujuan melihat apakah bibliotherapy dapat memengaruhi konsep diri remaja. Subjek dalam penelitian ini adalah mahasiswa (N = 41) yang memiliki skor konsep diri berkategori “cukup” sampai “negatif,” yang dengan random assignment dibagi menjadi 3 kelompok, yaitu kelompok bibliotherapy dan sharing, kelompok bibliotherapy saja, dan kelompok kontrol. Hasil uji ANOVA menunjukkan adanya perbedaan konsep diri yang signifikan pada delta pretest-posttest (p = 0.017< 0.05). Dari hasil uji posthoc terlihat bahwa yang berbeda signifikan adalah kelompok kontrol (KK), sementara antara kelompok eksperimen (KE)-1 dan KE-2, tidak terdapat perbedaan yang signifikan. Hal ini berarti bibliotherapy dapat meningkatkan konsep diri baik diberikan dengan sharing kelompok maupun tanpa sharing kelompok.
