Abstract

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.

Abstract

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.

Abstract

Water is one of the most basic needs of all living things, including humans. Water is essential for life because it serves as a barometer for the quality of human life, specifically health. Drinking water is safe for human consumption if it meets the physical, microbiological, chemical, and radioactive requirements specified in the mandatory and additional parameters. In microbiology, the mandatory parameter for drinking water quality is a total of 0 coliform bacteria per 100 ml. The purpose of this study is to quantify the content of coliform bacteria in drinking water at refill drinking water depots in Tahoa Village, Kolaka Regency, that meet or do not meet the requirements outlined in Permenkes No. 492 of 2010. Six refill drinking water depots in Tahoa Village, Kolaka Regency, were used as samples. The method used in this descriptive quantitative research is the most probable number (MPN), which consists of a prediction test and a confirmation test. The results revealed that coliform bacteria were present in drinking water samples A, B, C, D, E, and F, with MPN index values of 240/100 ml, 240/100 ml, and 96/100 ml, respectively. Based on the results of 38/100 ml and 240/100 ml, it can be concluded that the drinking water at the refill drinking water depot in Tahoa Village, Kolaka Regency, does not meet the requirements of Permenkes No. 492 of 2010.

Abstract

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.

Abstract

Kacang hijau (Vigna radiata L.) merupakan salah satu bahan pangan yang banyak dikonsumsi oleh masyarakat luas, karena tergolong tinggi penggunaannya dalam masyarakat maka kacang hijau memiliki tingkat kebutuhan yang cukup tinggi. Berbagai faktor menyebabkan penurunan produksi kacang hijau, antara lain kesuburan tanah yang rendah, alih fungsi lahan, faktor iklim tidak mendukung, dan praktik budidaya tidak tepat. Penggunaan bahan organik dapat menjadi alternatif solusi untuk mengurangi ketergantungan terhadap penggunaan pupuk kimia dalam meningkatkan produktivitas tanaman. Pupuk kotoran kambing memiliki kandungan unsur hara nitrogen yang lebih tinggi dari pupuk kotoran hewan lainnya. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk organik kotoran kambing terhadap pertumbuhan dan hasil kacang hijau (Vigna radiata L,). Metode yang digunakan dalam penelitian ini yaitu rancangan acak kelompok (RAK). Dengan pemberian pupuk kotoran kambing dengan masing-masing dosis yaitu K0/kontrol, K1 (5 gr), K2 (10 gr), K3 (15 gr), dan K4 (20 gr). Pada hasil penelitian menunjukkan pada tanaman kacang hijau (Vigna radiata, L) dari hasil uji ANOVA untuk kelompok tidak memberikan pengaruh yang signifikan terhadap parameter pertumbuhan tinggi tanaman (0,26 < 4,46), jumlah cabang (2,710 < 4,46), umur berbunga (3,27 < 1,943), umur berbuah (0,87 < 0,07) dan jumlah polong (0,6 < 0,36), sedangkan untuk perlakuan memberikan pengaruh yang signifikan terhadap parameter umur berbunga (27,58 > 3,84) dan jumlah polong (32,32 > 3,84). Pada tanaman kacang hijau untuk kelompok tidak memberikan pengaruh yang signifikan pada parameter hasil berat 100 biji (0,40 < 4,46), jumlah biji normal (0,087 < 4,46) dan jumlah biji kecil (0,12 < 4,46). Namun, pada perlakuan memberikan pengaruh yang signifikan terhadap parameter hasil berat 100 biji (4,20 > 3,84) dan biji kecil (4,246 > 3,84) pada tanaman kacang hijau (Vigna radiata, L).

Abstract

Sampah plastik merupakan masalah besar, bukan hanya di Indonesia, tetapi di seluruh dunia. Pencemaran sampah plastik tidak hanya berdampak buruk terhadap lingkungan. Namun dapat menimbulkan dampak yang sangat berbahaya bagi biota laut. Mikroplastik yang tertelan oleh biota laut dapat menyebabkan gangguan metabolisme, iritasi sistem pencernaan bahkan menyebabkan kematian. Kandungan mikroplastik yang terakumulasi pada organisme laut dapat berpindah ke tubuh manusia melalui rantai makanan. Sampah plastik diyakini menjadi penyebab penyakit terumbu karang. Upaya pencegahan pencemaran sampah plastik harus dilakukan secara holistik dan melibatkan pastisipasi masyarakat. Salah satu upaya yang dapat dilakukan adalah sosialisasi mengenai dampak pencemaran sampah plastik terhadap biota laut dan kesehatan manusia kepada masyarakat pesisir. Tujuan kegiatan ini adalah meningkatkan pengetahuan dan kesadaran masyarakat tentang bahaya sampah plastik, sehingga dapat meningkatkan peran masyarakat dalam upaya pencegahan pencemaran sampah plastik dan pengelolaan lingkungan. Kegiatan ini melibatkan 17 orang mahasiswa dan dosen program studi pendidikan biologi, 15 orang mahasiswa peserta KKA dan diikuti oleh 37 orang warga desa Banabungi sebagai mitra. Kegiatan ini meliputi koordinasi, sosialisasi, aksi pengumpulan dan reduksi sampah dan evaluasi melalui quisioner. Hasil evaluasi menunjukkan pemahaman masyarakat meningkat sebesar 15,2%. Keberhasilan kegiatan juga terlihat pada partisipasi masyarakat dalam mengikuti kegiatan

Abstract

Pepper is a plantation commodity that belongs to the spice category and has an important role in Indonesia's economic growth. Southeast Sulawesi is one of the centers for the development of pepper plants, especially in the South Konawe area. The purpose of this study was to determine the effect of indigenous mycorrhizae on the growth of pepper plants which were carried out in Sindangkasih Village, West Ranomeeto District, South Konawe Regency. Analysis of dry weight and infection of indigenous mycorrhizae on the roots of pepper plants was carried out at the Agrotechnology Laboratory, Faculty of Agriculture, University of Haluoleo Kendari. Data analysis in this study used a single factor Randomized Block Design (RBD) with 4 treatments and 3 replications, so there were 12 trials. The treatment consisted of 4 levels, namely without mycorrhizae (A0), 10 grams of mycorrhizae (A1), 15 grams of mycorrhizae (A2) and 20 grams of mycorrhizae (A3). The results showed that the application of indigenous arbuscular mycorrhizae had an effect on the growth parameters of pepper plants in the form of plant height, number of leaves and number of tendrils, where A3 produced higher plant height, number of leaves and number of tendrils and was significantly different from other treatments. Treatment A2 was not significantly different from treatment A1 but significantly different from treatment A0 (without mycorrhiza). Mycorrhizal inoculation of 20 grams/polybag can cause root infection of pepper plants to increase by 80.00%.
