PERTUMBUHAN RUMPUT LAUT (Eucheuma cottonii) PADA KEDALAMAN AIR LAUT YANG BERBEDA DI DUSUN KOTANIA DESA ETI KECAMATAN SERAM BARAT KABUPATEN SERAM BAGIAN BARAT
Authors: Surni Wa 
Published: May 2020

Background: cottonii Eucheuma Seaweed is macro algae that live in the sea, generally in the bottom waters and attached to the substrate or other objects and also life floating on the sea surface. Part - part seaweed generally consists of Holdfast is a basic part of the seaweed that serves to attach to the substrate and thalus which forms the growth of seaweed that resembles branching. Seaweed growth is highly dependent on factors oceanography (physics, chemistry, and dynamics of movement or sea water), seaweed take nutrients from the surroundings by diffusion and osmosis through thallus wall.
Methods: Based on the results of research conducted in June 2011, and then do an in-depth study related to planting seaweed Eucheuma cottonii with different depths - the difference of up to 30 cm, 40 cm, and 50 cm in the village kotania coastal waters.
Results: The results showed that at a depth of 30 cm of growth is very good compared to the depth of 40 cm and 50 cm less growth in both .This can be caused due to the presence of light intensity on the surface of the sea water in comparison with the deeper parts.
Conclusion: The depth is good for the growth of seaweed is 30 cm below sea level with an average wet weight for 35 days (5 weeks) is 160 grams

Published: May 2020

Background: the sago flour is the main result of the sago palm, while the byproduct or waste sago generally used for animal feed, compost in mushroom growing media, or as raw material for the plywood industry. Sago waste by the people of Maluku called ela sago can also play a role in improving soil fertility in this case improve the physical, chemical and biological soil after going through stages of processing into granules and granule enriched compost.
Methods: The study design used was a randomized block design with three replications. The treatment consists of: without fertilizer (KGES1), compost granule 8 t ha-1 (KGES2), inorganic fertilizers (Urea, SP-36 and KCl) recommended dosage (KGES3), inorganic fertilizer + compost granule 8 t ha-1 (KGES4), ½ x doses of inorganic fertilizer + compost granule (8 t ha-1) (KGES5), 2 doses of inorganic fertilizer + compost granule 8 t ha-1 (KGES6), ½ x doses of inorganic fertilizer + compost granule 12 t ha -1 (KGES7) and 2 doses of inorganic fertilizer compost + 4 t ha-1 (KGES8).
Results: Compost granules ela sago and inorganic fertilizer significantly affect the physical properties of soil that is heavy volume of land (0.80 g cm-3), a specific gravity of soil particle (2:30 g cm-3), soil porosity (7.77%), drainage pore fast (23:54%), slow drainage pores (8.83%), pore water is available (11.62%), and pore water is not available (11:31). While plant growth (plant height) and dry seed corn grain yield respectively by 249.17 cm and 7.85 tonnes ha-1. A combination of compost and inorganic fertilizer granule able to increase the yield of 30-47% compared with inorganic fertilizer or compost granule alone. Excessive inorganic fertilizer application did not show the result of increased dry seeds shelled corn is real. Based on these results, a reduction of half a dose of inorganic fertilizer combined with granulated compost 12 t ha-1 yield of dry shelled corn grain yield highest (7.79 t ha-1) or increase the yield of 32% of inorganic fertilizer application.
Conclusion: Compost granules ela sago and inorganic fertilizer significantly affect soil physical properties ie soil bulk density (0.80 g cm-3), soil particle density (2:30 g cm-3), soil porosity (7.77%), soil macropore (23:54%), mesopore (8.83%), and micropore (11.62%). While plant growth (plant height) and dry seed corn grain yield respectively by 249.17 cm and 7.79 tonnes ha-1. A combination of compost and inorganic fertilizer granule able to increase the yield of 30-47% compared with inorganic fertilizer or compost granule alone. Excessive inorganic fertilizer application did not show the result of increased dry seeds shelled corn is real.

Published: May 2020

Abstract
Scientific attitudes are essential for students to improve their creative and critical thinking skills. In fact, there are still many learning practices that focus on lecturers. Learning methods are still widely used in learning one of them is expository. Whereas the Expository method is a less effective method to improve the scientific attitude of students. Students will not be able to be scientific if they are not trained for such. To improve the scientific stance, the relevant learning methods are required. One of them is PJBL, a student-centered learning method. The advantages of PJBL learning are learning approaches that use critical thinking like revealing facts. This research was conducted to improve the attitude of students. The research method implemented is the action research model Kurt Lewin. With research procedure in 1 cycle is planning, application, observation, and reflection. The implementation was conducted for 2 cycles with 4 learning meetings. The results gained in this study were scientific attitudes of the students that were seen from the indicators of scientific attitudes have increased. The average increase in each student has reached 85%. So it can be concluded that the implementation of PJBL in improving student scientific attitudes is said to be effective.

Abstrak
Sikap ilmiah sangatlah penting bagi mahasiswa untuk meningkatkan kemampuan berpikir kritis dan kreatif. Pada kenyataannya masih banyak praktek pembelajaran yang berpusat pada dosen. Metode pembelajaran yang masih banyak digunakan dalam pembelajaran salah satunya adalah ekspositori. Padahal metode ekspositori merupakan metode yang kurang efektif untuk meningkatkan sikap ilmiah mahasiswa. Mahasiswa tidak akan dapat bersikap ilmiah jika mereka tidak dilatih untuk seperti itu. Untuk meningkatkan sikap ilmiah tersebut maka diperlukan metode pembelajaran yang relevan. Salah satunya adalah PJBL yaitu metode pembelajaran yang berpusat pada mahasiswa. Kelebihan pembelajaran PJBL adalah pendekatan pembelajaran yang menggunakan pemikiran kritis seperti mengungkap fakta-fakta. Penelitian ini dilaksanakan untuk meningkatkan sikap ilmih mahasiswa. Metode penelitian yang dilaksanakan yaitu action research model kurt lewin. Dengan prosedur penelitian dalam 1 siklus adalah perencanaan, penerapan, observasi, dan refleksi. Pelaksanaan dilakukan selama 2 siklus dengan 4 pertemuan pembelajaran. Hasil yang didapatkan dalam penelitian ini yaitu sikap ilmiah mahasiswa yang dilihat dari indikator-indikator sikap ilmiah mengalami kenaikan. Kenaikan rata-rata setiap mahasiswa sudah mencapai 85%. Sehingga dapat disimpulkan bahwa penerapan PJBL dalam meningkatkan sikap ilmiah mahasiswa dikatakan efektif.
