In this research, we investigated the effects of supplementation of rice bran fermented with Effective Microorganism (EM4) on the biomass of tubifex worms cultured in the recirculation system. A Completely randomized design was made, consisting of 4 treatments and 3 replications. The experimental animals were treated with different types of feed, i.e. (A) unfermented rice bran, three times a day; (B) fermented rice bran, three times a day; (C) fermented rice bran, 5 times a day; (D) fermented rice bran, 7 times a day. They were reared in a wood box (100 × 50 × 15 cm 3 ), while a mixture of fermented rice bran and mud was applied as their growth medium. Tubifex worms were grown in the medium at a density of 100 g/m 2 , and supplemented with fermented rice bran at a dose of 500 g/box, with various frequency levels of 3, 5 and 7 times a day. Biomass of the worm and water quality was observed. As a result, we found that the addition of fermented rice bran at a rate of 5 times a day (treatment C) exhibited the greatest biomass growth, reaching up to 104,33 g/m 2 .

Penelitian ini bertujuan memberikan gambaran serta penjelasan tentang Pengembangan Objek Wisata Alam Uwae Pellae dalam Meningkatkan Pendapatan Retribusi WisataDi DinasPariwisatadan Kebudayaan Kabupaten Sinjai. Jenis penelitian ini menggunakan tipe penelitian deskriptif kualitatif. Teknik pengumpulan data adalah observasi, wawancara terhadap sejumlah informan.

The revolution of industry 4.0 becomes a new challenge to prepare the students to have high computing technology ability. This demand changes the conventional learning method using more manual tools into the one using digital-based computing ware. Interactive multimedia is a type of media operated using handheld and mobile computing ware, android-based smartphone. Interactive multimedia can display information in text, image, audio, video, and animation formats. Information can be presented real time anytime and anywhere in real environment setting. Interactive multimedia potentially makes the learning process running effectively. In addition, interactive multimedia potentially improves students' learning motivation and outcome and practices high-order thinking skills such as analytical, critical, and creative thinking skills. The use of interactive multimedia in the learning needs the synergy of technology ware availability, students' preparedness, teachers' preparedness, and school regulation, and stakeholders. The methods employed in this research were observation on learning activity and literature study referring to various relevant sources. Thus, android-based interactive multimedia is one of solutions to improve the quality of learning and to prepare the students for dealing with the competition in industrial revolution era 4.0.
