Abstract

Aktivitas masyarakat yang lebih mudah karena adanya teknologi saat ini melahirkan inovasi di antaranya e-commerce. Shopee paylater adalah layanan fitur terbaru shopee untuk memberikan pinjaman ke pengguna. Tujuan dari penelitian ini adalah untuk mengetahui dampak apa saja yang dirasakan oleh pengguna paylater akibat keterlambatan pembayaran dan untuk mengetahui sudut pandang agama islam mengenai Shopee paylater. Jenis penelitian yang akan digunakan yaitu dengan pendekatan kualitatif. Peneliti mengumpulkan data dengan cara mengamati dan wawancara kepada pihak yang menggunakan Shopee Paylater. Hasil dari penelitian dapat disimpulkan bahwa dampak yang dialami peminjam yaitu Pengguna mendapatkan denda sebesar 5% dari total tagihan. (b) Menerima penagihan lewat via telepon maupun email. (c) Akun peminjam akan dibatasi (tidak dapat melakukan transaksi secara online pada aplikasi Shopee) jika keterlambatan sudah sampai satu bulan. (d) Jika sampai tidak dapat ditagih, maka data peminjam akan masuk ke Biro Kredit. Dan tidak dapat meminjam pada lembaga lain. Berdasarkan akad Qard maka Shopee Paylater tersebut tidak diperbolehkan secara hukum karena beberapa alasan di antaranya: (a) Shopee Paylater memberikan keuntungan secara pribadi bagi Shopee karena penggunaan Shopee Paylater hanya digunakan untuk aplikasi Shopee saja. (b) Jatuh tempo pembayaran tidak genap satu bulan sesuai dengan keterangan pada Shopee Paylater. (c) Ketidakjelasan bunga yang diberikan pada cicilan 2x dan cicilan 3x.

Abstract

The purpose of this study was to determine (1) the tolerance of earthworms (Eudrilus eugeniae) to the herbicide 2,4-D dimethyl amine, and (2) the response of increased biomass, behavior, and morphology of earthworms (Eudrilus eugeniae) when exposed to subletal doses of the herbicide 2,4-D dimethyl amine. This research is an experimental research conducted in two stages of research. The first stage to look at herbicide toxicity, includes LD50, upper threshold, and lower threshold. The second stage is a follow-up test study using a one-factor Complete Random Design (RAL) to determine the effect of subletal dose of LD50-48 hours on the increase in biomass, behavior, and morphology of earthworms (Eudrilus eugeniae). The object of the study is the earthworm (Eudrilus eugeniae) which already has a clitelum with a biomass of 25 grams for each treatment tank. Data analysis was carried out with Proit Analysis to determine the upper threshold, lower threshold, and LD50 value while the analysis of the difference in earthworm biomass from the treatment group was carried out using  the One-Way ANOVA test  at a significance level of 95%. The average treatment was further tested using the DMRT test in the SPSS version 24.0 program. The results showed that: (1) earthworm tolerance to the herbicide 2,4-D dimethyl amine, at the  upper threshold value of 9996.014 ppm, the lower threshold of 3409.972 ppm, the LD50-48 hours of 9015.858 ppm which is practically non-toxic, (2) the response of earthworms (Eudrilus eugeniae) when exposed  to subletal doses of the herbicide 2,4-D dimethyl amine herbicideIt is characterized by a reduced earthworm appetite, a shrinking body shape, and a decrease in biomass.

Abstract

This study aims to determine the effect of a combination of fermented tofu pulp, coconut pulp, rice bran, and cabbage waste on: 1) the growth and; 2) development of BSF larvae. The study was conducted using a completely randomized design (CRD) at the Biology Garden of the Faculty of Mathematics and Natural Sciences, Yogyakarta State University. The independent variables used were combinations of feed media with fermented tofu pulp, cabbage waste, coconut pulp, and rice bran in 3 treatments. The dependent variables observed were growth, including biomass increase and individual larval growth, as well as BSF larval development. The control variables of the study were container size, initial BSF larva biomass, and BSF larva age, which was 10 days after hatching. Observations of individual growth and BSF larva development were conducted once a week. BSF larva biomass measurements were conducted every 2 weeks using the gravimetric method. Data analysis for this study used ANOVA and Duncan's Multiple Range Test (DMRT). The combination of fermented tofu pulp, coconut pulp, rice bran, and cabbage waste had a significant effect (P<0.05) on the increase in biomass and individual growth of BSF larvae, as well as on the speed of BSF larvae development into pupae.
