The mangrove ecosystem has a higher ability of CO 2 absorption than other vegetations. However, the effort to establish the mangrove to be a carbon stock area has not been achieved. Makassar has Tallo River, covered with mangrove vegetation along its riverbank, which is potent to be managed as a green open space. The observations indicated that Tallo River was located in the center part of Makassar city and was dominated by Nypa fruticans along the riverbanks in 18,514 trees and a density of 4,256 trees/ha, stored carbon of 21.82 tons C/ha, and absorbs 80.02 tons CO 2 /ha. Rhizophora mucronata was the second dominant species in 8.492 trees and density of 2,352 trees/ha, stored carbon of 19.94 tons C/ha, and absorbs 73.13 tons CO 2 /ha. The third dominant species was Avicennia alba in 2,421 trees and density of 3,228 trees/ha, stored carbon of 263.85 tons C/ha, and absorbs 197.89 tons CO 2 /ha. The density and ability to absorb values of the mangrove is highly suitable to be managed for a green open space to supply fresh air and CO 2. INTISARI Ekosistem mangrove memiliki kemampuan menyerap CO 2 lebih tinggi dibandingkan dengan vegetasi tumbuhan lainnya. Namun upaya pengelolaannya sebagai kawasan penyimpan stok karbon masih belum maksimal. Kota Makassar memiliki Sungai Tallo yang sepanjang bantarannya ditumbuhi oleh vegetasi mangrove dan sangat potensial untuk dikelola sebagai ruang terbuka hijau. Hasil pengamatan menunjukkan bahwa Sungai Tallo terletak tepat di tengah kota Makassar dan sepanjang bantaran sungai didominasi oleh spesies Nypa fruticans dengan jumlah 18.514 pohon dan kerapatan 4.256 pohon/ha, menyimpan karbon sebesar 21,82 ton C/ha, menyerap 80,02 ton CO 2 /ha. Spesies dominan kedua adalah Rhizophora mucronata dengan jumlah 8.492 pohon dan kerapatan 2.352 pohon/ha, menyimpan karbon sebesar 19,94 ton C/ha, menyerap 73,13 ton CO 2 /ha. Spesies dominan ketiga yaitu Avicennia alba dengan jumlah 2.421 pohon dan kerapatan 3.228 pohon/ha, KATA KUNCI ekosistem mangrove kerapatan mangrove serapan karbon stok karbon Sungai Tallo
A b s t r a c t A r t i c l e I n f oThe purpose of this study was to determine the effect and optimal dose of liquid organic fertilizer mikrobat on vegetative growth of local aromatic rice. The results showed that liquid organic fertilizer mikrobat in accession of Pare Mansur and Pare Pinjan rice varieties had a significant effect on growth of plant height (4, 8, and 12 weeks after planting), number of tillers (10 and 12 weeks after planting), wet weight, dry weight of plants and root length. Accession Pare Pinjan showed growth of plant height, number of tillers, wet weight, dry weight of plants and root length better than Pare Mansur.The use of liquid organic fertilizer at K1 concentration dose of 5% (5 ml of liquid organic fertilizer + 95 ml of water) is the best dosage for local aromatic rice Enrekang accession Pare Pinjan.
Chili is one of the spices that are consumed by many Indonesians. It has several vitamins, one of which isvitamin C and ß-carotene is a pro-vitamin A which plays an important role in the formation of vitamin A. The studywas conducted in August 2018 and sampling from the regions Toraja and Malino. This study aims to determine thelevels of vitamin C in several types of chilli obtained by using iodine titration method and the levels of ß-caroteneby spectrophotometric method at a wavelength of 460-480 nm. The chili sample was first measuredmorphologically, weighed by base and dry weight and its water content. The test results showed vitamin C levels ofPepper Katokon Toraja Capsicum annuum L. Var. Sinensis is tested with seeds (0.129% / 10 g) and seedless(0.182% / 10 g). Large Chili Capsicum annuum L. Var. Abreviatum Fingerhuth was tested with seeds (0.220% / 10g) and seedless (0.223% / 10 g). Curly Chili Capsicum annuum L. Var. Longum sendt was tested with seeds(0.537% / 10 g) and seedless (0.592% / 10 g). Test results showed the levels of β-carotene Pepper Katokon TorajaCapsicum annuum L. Var. sinensis were tested with seeds (5.888mg / kg) and seedless (6.073mg / kg). Large ChiliCapsicum annuum L. Var. Abreviatum Fingerhuth was tested with seeds (5.529mg / kg) and seedless (6.338mg /kg). Curly Chili Capsicum annuum L. Var. Longum sendt was tested with seeds (6.655mg / kg) and seedless(6.942mg / kg). Conclusion The highest content of vitamin C and ß-carotene was found in Curly Chili Capsicumannuum L. Var. Longum sendt without seeds.
Marine aquaculture is now starting to develop rapidly along with the decreasing catches of marine fisheries. The marine aquaculture sector was expected to be the largest supplier of the marine and fisheries sector in the future. Efforts to improve marine aquaculture activities are increasingly encouraged, including efforts to optimize other roles as conservation areas. This research was conducted in the waters of Barru, South Sulawesi from February to August 2018. The aim of the study was to determine the types of fish which associated with seaweed cultivation and floating net cages. In addition to know the length of fish to associate with seaweed cultivation and floating net cages. The research was carried out by observing the location of the marine culture. Samples was identified at the research location, and taken to the laboratory for further identification of samples that cannot be directly identified. Observations were made around the cultivation area. In this study we found that fish family associated with aquaculture seaweed and
