Cocoa (Theobroma cacao L.) is one of the people's plantation crops with promising prospects because it can flower and bear fruit throughout the year. One of the efforts to improve the quality of cocoa seeds is by increasing the viability and vigor of seeds through seed invigoration techniques. This study aimed to determine the effect of biopriming invigoration treatment techniques in increasing cocoa seeds' viability, vigor, and growth. This research was conducted at the Laboratory of Agronomy Unit of the Faculty of Agriculture of Halu Oleo Kendari from April to May 2019. This study used a completely randomized design (CRD) consisting of 4 treatments: Control (B0), Bio-priming Bacillus sp. CKD061 (B1), Bio-priming Pseudomonas flourescent (B2), a combination of Bio-priming Bacillus sp. CKD061 with Pseudomonas fluorescent. Each treatment was repeated three times, so there were 12 experimental units. The data obtained were analyzed using variance analysis and continued using the Least Significant Difference Test (LSD). Based on the results of research that biopriming treatment using rhizobacteria has the best influence on the viability, vigor and growth of cocoa seeds.

Sea urchins are marine invertebrates that are grouped in the Echinoidea class and Echinodermataphylum. Mawasangka is a district that has a large coastal area with a fairly good seagrass and coral reef ecosystem that plays an important role in the life cycle process of marine organisms, for instant as a habitat and food source for sea urchins. However, until now, information about the diversity of sea urchins in the coastal areas in Mawasangka District has not been reported. Thus, this research is very important. This research began with a location survey, field observation, and sampling. Supporting data such as temperature, pH, brightness, depth and salinity were also measured. The results showed that the number of species in 3 research locations in the coastal area of Mawasangka District was 5 species, consisting of 3 species from the genus Diadema, namely Diadema cytosum, Diadema antillarium, and Diadema savignyi, and 2 species from the Echinotrix genus, namely Echinothrix calamaris and Echinothrix diadema. The highest number of species diversity was found on the Pasi Kobungi beach. This happened because the habitat and environmental conditions at Pasi Kobungi Beach were very compatible for 5 species found. The species with the greatest abundance was sea urchins from the species of Diadema cytosum. It was found out that the coral reef substrate and seagrass in three research locations were important habitats for the growth of Diadema setosum and were easy to adapt to the environment. Due to the abundance of sea urchins from the Diadema cytosum species as well as many benefits of it for the environment, it can be concluded that the condition of the coastal area of Mawasangka District is still classified as healthy and well preserved.

Indonesian territory is dominated by Rhizophora mangrove vegetation, but in the Kolaka area, especially Induha Village, there is no information about this type of mangrove, so research is needed. The purpose of this study is to determine the vegetation Rhizophora mangroves sp. and fauna vertically in the mangrove forest in Induha Village. The method used is the Point Centered Sampling Method (PCQM). The results obtained, there are 3 types of mangrove Rhizophora namely Rhizophora apiculata, Rhizophora mucronata, and Rhizophora stylosa, with the highest relative density being Rhizophora apiculata at the seedling level (42.13%), sapling (57.50%) and at the tree level (38.31%). The highest relative frequency was Rhizophora apiculata at seedling (35%), sapling (45%) and tree (34.5%) levels. Rhizophora apiculata has the highest relative basal area value at the seedling (50%), sapling (84.83%) and tree (52.34%) levels. The highest relative canopy was Rhizophora apiculata, at the sapling (57.2%) and tree (35.3%). The highest Important Value Index was Rhizophora apiculata, at the seedling level (1 25.3 %), sapling (24 4.5 %) and tree (1 56.1 %). The fauna vertically identified as many as 5 types of species including hermit crabs, sea slugs, caterpillars, weaver ants and black ants. The conclusion of this study is that there are 3 types of mangroves identified in the mangrove forest dominated by Rhizophora apiculata and 5 fauna species. Environmental factors that have been observed support the survival of mangrove species in Induha Village, both in zone 1 and in zone 2, especially the Rhizophora apiculata.

Patchouli plants (Pogostemon cablin) in Batu Putih Village often die from erratic seasons. Excess soil water content during the rainy season causes plants to rot and die. In other cases, the death of patchouli is also caused by a lack of water content in the soil. This study aims to determine the effect of soil water content on the growth of patchouli (Pogostemon cablin) in Batu Putih Village, Batu Putih District, and North Kolaka Regency. This study used a randomized block design (RBD) method with two treatment factors, namely the material type and the groundwater concentration. Each type of material consisted of patchouli, soil and water, while the groundwater concentration consisted of watering 100% (500 ml), 60% (300 ml) and 40% (200 ml). The results showed that watering with 100% groundwater concentration (500 ml) gave the best growth compared to water at 60% and 40% groundwater concentrations. However, the results of the Anova test showed that watering with 100%, 60%, and 40% groundwater concentrations did not have a significant effect on plant growth, it was suspected that water was not the dominant factor in the patchouli plant growth process. Keywords: Patchouli, growth, soil moisture content, Pogostemon cablin.

This study aims to determine the effect of tofu liquid waste on the growth of mustard greens (Brassica juncea L.). The method used in this study was a Randomized Block Design (RAK) which consisted of 5 treatment levels and 3 replications to obtain 15 experimental polybags. The results of the ANOVA test for the group showed that the height growth of the mustard greens did not have a significant effect, namely FCount (0.52) FTabel (4.46) and for the treatment did not have a significant effect, namely FHitung (0.27) FTabel (4,46), It is suspected that excess nitrogen will produce young shoots that are soft/weak and vegetative, acidify soil reactions, lower soil pH, and be detrimental to plants because it will bind other nutrients so that it will be difficult for plants to absorb them and fertilization will become less effective and inefficient. The results of the ANOVA test on the number of leaves showed that the treatment of liquid organic fertilizer from tofu liquid waste for groups had a significant effect, namely FHitung (5.39) FTabel (4.46), it was suspected that the amount of nutrients absorbed by plants had an effect on the process of leaf formation because the process of forming new cells is very closely related to the availability of nutrients needed by plants. the results of the ANOVA test on the fresh weight of mustard greens showed that the treatment of liquid organic fertilizer from tofu liquid waste for the group had a significant effect, namely (7,69) FTabel (4,46), as well as treatment had a significant effect (22,83) FTabel (4,46), It is suspected that fertilizer is absorbed optimally so that it can support plant metabolic processes and have a good effect on the growth of fresh weight in mustard greens.

Many species of sea urchins (Echinoidea) can be found in the waters of Sembalagi Beach, Siompu Island. However, the diversity of sea urchins (Echinoidea) on the coast has not been scientifically researched and published. This study aims to determine the types, hunting, poaching and dominance of sea urchins (Echinoidea) at Sambalagi Beach, Siompu Island, South Buton Regency. This study uses a quantitative descriptive method with observation techniques. There are three research stations, namely station I (rocky and seagrass substrate), station II (sandy and seagrass substrate), and station III (rocky and seagrass substrate). The data obtained were analyzed using the formulation of documents, documents, secrecy and Shannon-Winner domination. The results showed that there were 5 species of sea urchins (Echinoidea) which namely Diadema setosum, Echinothrix calamaris, Tripneustes gratilla, Echinometra mathaei and Salmacis sphaeroides. The species diversity index (H') for the three abnormalities was classified as moderate, namely station I (H' 1,34), station II (H' 1,18) and station III (H' 1,22). The highest relative abundance of Echinoidea was found in Tripneustes gratilla species at Station II (37,67%) which had a lot and the lowest relative decline index was found in Echinothrix calamaris and Echinometra mathaei at Station III (1,52%) less abundant. The highest evenness index is at station II (0,85) which is very even and the lowest is at station III (0,76) which is more evenly distributed. And the highest dominance index is at station II (0,32) with moderate dominance and the lowest dominance index is at station I (0,29) with low dominance.
