Kota Padang menghadapi tantangan serius terkait manajemen sampah yang dipicu oleh perilaku membuang sampah sembarangan, terutama ke pinggiran sungai dan pinggir jalan. Dalam upaya penanganan, Dinas Lingkungan Hidup (DLH) Kota Padang telah melakukan langkah-langkah seperti mendirikan posko pemantauan dan pengawasan K3 serta memberikan sosialisasi terkait waktu pembuangan sampah yang diatur dalam Peraturan Walikota (Perwako). Selain itu, sanksi administratif dan pidana diberlakukan bagi pelanggar. Meskipun DLH juga melaksanakan program pengurangan sampah dengan pendekatan reduksi dari sumbernya melalui pembinaan bank sampah, tingkat pengelolaan sampah masih belum optimal karena masih banyaknya sampah yang dibuang secara ilegal atau dibakar sendiri oleh penduduk. Pertumbuhan penduduk yang cepat di Kota Padang juga menjadi faktor yang memperparah masalah lingkungan, termasuk masalah sampah, sehingga diperlukan sinergi antara pemerintah, masyarakat, dan pihak terkait lainnya untuk mencapai pengelolaan sampah yang lebih baik dan berkelanjutan.

Breadfruit has a fairly high starch content of 84.28%, the utilization of breadfruit itself is still not optimal. In Indonesia, breadfruit can thrive in one of the breadfruit-producing cities, namely the city of Padang. One of the uses of breadfruit is in the manufacture of edible films. Edible film is a thin plastic that has a size smaller than 0.3 mm which serves to protect food products. The purpose of this study was to determine the effect of carrageenan on the tensile strength and biodegradation of edible films from breadfruit starch. This study used the addition of carrageenan with variations in concentrations of 0%, 0.5%, 1%, 1.5%, and 2%. Edible film was tested for tensile strength and obtained values at 0% 2.046, 0.5% 4.252, 1% 7.678, 1.5% 4.139, 2% 3.829 where the optimum tensile strength value was at 1% with a tensile strength of 7.678 Mpa while the biodegradation had percent loss at least at a concentration of 2% with a percent loss yield of 11.5%. The higher the concentration used, the more difficult it is for the edible film to be degraded in the soil.

Abstract : Edible film is a thin plastic with a thickness of less than 0.25 mm which serves to protect food products. The purpose of this study was to determine the optimum concentration of addition of chitosan to edible film made from avocado seed starch on mechanical properties and to compare the mechanical properties of edible film with the value of Japenese Industrial Standard (JIS) Z1707. This research was conducted by adding 4% polyethylene glycol as a plasticizer and varying the addition of chitosan with a concentration of 0%; 0.5%; 1%; 1.5%; and 2%. The optimum conditions for the addition of chitosan at a concentration of 1%, with a tensile strength value of 1.235 Mpa, an elasticity value of 4.643 Mpa, and an elongation value of 0.266 Mpa. The tensile strength and elasticity values of the edible film have met the Japenese Industrial Standard (JIS) Z1707 but the elongation value has not met because the edible film produced is fragile so it breaks easily and causes the edible film to have a low elongation value.
