Abstract

Danu Rawa Taliwang is a large body of water that receives sources of heavy metal pollution from human activities such as agriculture and mining. By using bioindicators such as fish, heavy metals have been detected in the waters. The aim of the study was to determine the content of heavy metal mercury (Hg) in the Rice Field Snail (Pila ampullacea) originating from Lake Rawa Taliwang to enrich Ecotoxicology course material. The special benefit is to protect consumers who consume fish from heavy metal contaminants.  Sample Snail was put into a plastic bag and then stored in a sample box. The research sample was then analyzed at the Environmental Laboratory Center for the West Nusa Tenggara Environment and Forestry Office. The method of data analysis was carried out by taking muscle tissue from snails and then analyzing the content of heavy metals in the form of Hg using an Atomic Absorption Spectrophotometer. Heavy metals in snail tissue were measured after adding concentrated HNO3 and HClO4, which were heated at 60-70ºC for 2-3 hours until the solution was clear. Ready samples were measured by AAS using an air-acetylene flame. The conclusion of this study is that the heavy metal content of Hg in rice field snails (Pila ampullacea) originating from Lake Rawa Taliwang to enrich Ecotoxicology course material ranges from 0.96 ppm to 1.91 ppm.

Abstract

Tofu dregs have a fairly high protein content because not all of the protein content is decomposed during the production of tofu. Tofu dregs are not put to good use, in fact many people actually dispose of waste which causes environmental pollution. The aim of the study was to determine the effect of NPK fertilizer and tofu dregs organic fertilizer, as well as the combination of these fertilizers on the growth of ground water spinach (Ipomea reptans Poir). The type of research is an experimental 4x4 factorial with a completely randomized design. The first factor was NPK fertilizer which consisted of 4 levels (0, 0.4, 0.8 and 1.2 g/100 ml of water). The second factor was tofu dregs organic fertilizer (0, 50, 100, 150 g/3 kg soil) which consisted of 16 treatment combinations. Test the research hypothesis using TWO WAY ANOVA. The results showed that the application of NPK fertilizer and organic tofu dregs had an effect on fresh weight, plant height, dry weight, and number of leaves. However, it has no effect on leaf area. Application of organic tofu dregs fertilizer at a dose of 150 g/3 kg of soil, and NPK fertilizer 0.4 and 0.8 g/100 ml of water resulted in the best growth of kale plants at the age of 30 days.

Abstract

Rawa Lake Taliwang is the lifeblood of the West Sumbawa Regency community. The lake is surrounded by extensive agricultural areas, making the activities of local farmers a significant contributor to the accumulation of heavy metals in the region. This study aims to determine the cadmium (Cd) content in snakehead fish (Channa striata ) and assess its suitability for consumption. Sampling was conducted using purposive sampling with direct observation at Lake Rawa Taliwang . Nets or traps were employed at two stations, with two replications at each station. Data analysis involved calculating the cadmium content in the laboratory using Atomic Absorption Spectroscopy (AAS). The results revealed that the cadmium concentration in snakehead fish from Lake Rawa Taliwang was 0.45 mg/kg (ppm). This concentration exceeds the permissible limit for metal contamination in food, as stated in BPOM Regulation Number 9 of 2022. As a result, the snakehead fish is deemed unfit for consumption.

Abstract

It is important to carry out research on heavy metal in fish body. The specific aims and targets of this research are: Want to know the metal content of Cadmium (Cd) in Ricefield eels (Monopterus albus) which comes from Rawa Taliwang Lake. The specific benefit is to protect consumers who consume fish from heavy metal contamination. The research was carried out at Rawa Taliwang Lake, namely in an area that is submerged in water. There are 2 research stations, namely in the eastern and western parts of the lake. Data collection method was carried out using traps (Bubu). Four Ricefield eel samples were taken at each station. Next, the rice eel samples were put into a plastic bag and then stored in a sample box. The research samples were then analyzed at the Mataram Uviversity analytical laboratory and at Environmental Laboratory of the Environmental and forestry services West Nusa Tenggara Province.  The data analysis method is carried out by taking the tissues from the Ricefield eel muscles, and then analyzed for Cd heavy metal content by using Atomic Absorption Spectrophotometer. Measurement of heavy metals in Ricefield eel tissue was carried out by adding concentrated HNO3 and HClO4 , heated at a temperature of 60-70ºC for 2-3 hours until the solution was clear. Samples are ready to be measured with AAS using an air-acetylene flame. The conclusion of this research is that the content of Cd heavy metal in Ricefield Eels (Monopterus albus) originating from Rawa Taliwang Lake ranges from 2.55 - 4.01 mg/kg (ppm).

Abstract

Remaja merupakan kelompok usia yang rentan terhadap pengaruh lingkungan dan perubahan sosial. Pada masa ini, cenderung masih emosional dan labil. Tantangan yang dihadapi remaja saat ini adalah maraknya penggunaan zat adiktif, dalam berbagai bentuk seperti rokok, alkohol, maupun narkotika. Penggunaan zat adiktif di kalangan remaja tidak hanya mengancam kesehatan fisik, tetapi juga berdampak buruk pada perkembangan mental dan sosial. Selain itu, dapat menyebabakan penyempitan pembuluh darah, penyakit jantung coroner, naiknya kadar gula secara drastis, kemandulan, impoten, meningkatnya kadar lemak yang ada dalam tubuh dan meningkatnya kelahiran prematur, pendidikan, dan kehidupan sehari-hari secara keseluruhan. Kesehatan remaja merupakan aspek penting yang harus mendapatkan perhatian serius dari berbagai pihak. Oleh karena itu, sosialisasinya pada siswa mengenai dampak negatifnya terhadap kesehatan menjadi penting.
