Judul: Reclapan: Solusi Permasalahan Limbah Rumah Tangga Berbasis Aplikasi untuk Mendorong Sirkular Ekonomi
Abstrak: Pengelolaan limbah di Indonesia merupakan permasalahan yang belum terselesaikan, faktor seperti fasilitas yang kurang memadai, mekanisme pengelolaan yang belum efektif dan kebiasaan masyarakat menjadi penyebabnya. Penelitian ini bertujuan untuk merancang solusi berupa prototype aplikasi dan model bisnis yang sesuai dengan perilaku dan harapan serta permasalahan dalam pengelolaan limbah rumah tangga. Penelitian ini menggunakan metode customer discovery dan Lean Canvas dengan 100 responden pada tahap uji masalah dan 69 responden pada tahap uji solusi. Uji masalah menunjukkan bahwa sebesar 86 persen responden mengalami permasalahan seperti sampah tepilah tercampur kembali ketika pengangkutan, tidak memiliki tempat sampah berdasarkan jenis sampah, kurangnya frekuensi pengangkutan sampah, letak tempat pembuangan yang jauh dan fasilitas pembuangan yang kurang memadai. Solusi dirancang dengan menerapkan prinsip-prinsip ekonomi sirkular yang dikemas menjadi sebuah aplikasi penghubung antara rumah tangga yang memiliki permasalahan pengelolaan sampah dengan perusahaan yang kesulitan mendapatkan bahan baku daur ulang berkualitas. “Reclapan” mendorong aksi pemilahan yang kreatif dan menyenangkan dengan fitur gemifikasi dan reward berupa voucher belanja serta fitur lain yang dapat menyelesaikan sebagian besar permasalahan pengelolaan sampah rumah tangga.

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
