Abstract

The increase in the human population causes the amount of organic and inorganic waste to increase. The decomposition of inorganic waste is relatively longer compared to organic waste, therefore it is very harmful to the coastal environment. The purpose of this study was to determine the type, weight, distribution, density, and to compare the density and type of inorganic waste at Sebalang Beach and Tanjung Selaki Beach. Garbage collection and measurement of oceanographic parameters were carried out directly from March to April 2020. Garbage was collected on a 100 meter transect following the shoreline at each point at high tide and low tide. Current and wave were measured at two points with four repetitions. Waste data is separated by type, weight and presented descriptively. The results showed that the amount of macro-debris waste was higher than meso-debris waste with plastic waste that was more dominant than other types of waste. Sebalang Beach has a higher density of trash than Tanjung Selaki Beach.

Abstract

Kegiatan “Budidaya Lele Berbasis Teknologi Bioflock pada Kelompok Pembudidaya Ikan Mandiri Sentosa di Kecamatan Jati Agung Lampung Selatan" merupakan kegiatan transfer teknologi kepada masyarakat, yang sejalan dengan salah satu visi LPPM Unila. Pada kegiatan ini akan didiseminasikan teknologi bioflok dalam kegiatan budidaya ikan lele. Teknologi bioflok dalam budidaya perikanan menerapkan prinsip asimilasi nitrogen oleh bakteri heterotrof melalui modifikasi rasio C/N dalam air. Sasaran dari program ini adalah mitra kelompok pembudidaya ikan (pokdakan) Mandiri Sentosa di Kecamatan Jati Agung, Lampung Selatan. Program ini memiliki tujuan; 1) Pemahaman kelompok mitra dalam menggunakan teknologi bioflock sebagai solusi pengelolaan kualitas air budidaya ikan, serta 2) Membangun kemitraan dan kerjasama yang efektif antara perguruan tinggi dengan kelompok masyarakat di Kecamatan Jati Agung. Metode yang digunakan meliputi survei, pelatihan, denplot teknologi bioflock, pendampingan, dan evaluasi keberhasilan program. Kegiatan pengabdian kepada masyarakat ini terbagi menjadi 2 tahap yaitu tahap persiapan dan tahap pelaksanaan. Tahap persiapan meliputi: survei lokasi, sosialisasi kepada mitra, dan persiapan perlengkapan. Sedangkan tahap pelaksanaan meliputi: pelatihan budidaya ikan lele dengan teknologi bioflock, penyerahan paket teknologi bioflock, dan evaluasi kegiatan. Berdasarkan kegiatan pengabdian yang sudah dilakukan maka dapat disimpulkan bahwa adanya peningkatan pemahaman mitra mengenai penerapan teknologi bioflok hingga 100%, adanya manfaat yang diperoleh mitra melalui pelatihan budidaya ikan lele menggunakan teknologi bioflok, serta terciptanya kemitraan dan kerjasama yang efektif antara perguruan tinggi dengan kelompok masyarakat di Kecamatan Jati Agung, khususnya kelompok mitra Mandiri Sentosa.

Abstract

Utilization of ex-sand pit lakes for aquaculture is difficult due to low water quality and high concentrations of iron (Fe). Phytoremediation using aquatic plants has been proven to be effective in reducing Fe in waters. This study aims to determine the growth, feed conversion efficiency and survival rate of tilapia (Oreochromis niloticus) cultured with ex-sand mining water media with phytoremediation treatment. Phytoremediation treatment was carried out by Eichhornnia crassipes, Azolla pinnata, and Salvinia molesta. Fish culture experiments were carried out in plastic tarpaulin tanks for 40 days, with ad satiation feeding, three times a day using the commercial feed. The results showed that phytoremediation with aquatic plants had succeeded in reducing Fe to a level suitable for fish culture. Fish culture experiments showed an absolute length growth rate of 0.09-0.18 cm/day and an absolute weight growth rate of 0.11-0.16 g/day. The feed conversion ratio was 1.18-1.40 and the survival rate was 98.04-99.08%. The survival rate of tilapia is high, the feed conversion ratio is medium and growth is low. The high environmental temperature and the decrease in water quality due to the absence of water changes and aeration are suspected of causing the low growth of fish. Therefore, further research with water change and aeration experiments and the use of other species of fish is needed to follow up the results of this study.
