Soal Kd 2.4. mendeskripsikan Cara-cara Menangani Limbah

The correct answer is "Reuce, reduce, and recyele". The 3 R's refer to the principles of waste management: Reduce, Reuse, and Recycle. "Reuce" and "reduce" both mean to decrease or minimize the amount of waste generated. "Recyele" refers to the process of collecting and processing materials that would otherwise be thrown away as trash and turning them into new products. This answer accurately includes all three principles of waste management.

BOD stands for Biochemical Oxygen Demand, which refers to the amount of oxygen required by bacteria to decompose or oxidize organic substances present in wastewater. This characteristic determines the level of organic pollution in the water and indicates the potential for the water to support aquatic life. By measuring BOD, we can assess the level of organic pollutants in wastewater and determine the effectiveness of treatment processes in removing these pollutants.

Nata de coco is a product made from coconut water that has been fermented and processed. It is known for its jelly-like texture and is often used as a dessert or ingredient in various dishes. Nata de coco is also believed to have diuretic properties, which can help in promoting urination and thus aiding in the process of eliminating waste from the body. Therefore, nata de coco is the correct answer as it is a useful product made from coconut water that can assist in urination.

Instalasi pengelolaan air limbah biasa disebut IPAL. IPAL stands for Instalasi Pengolahan Air Limbah, which is a facility or system used to treat and manage wastewater. It is responsible for removing pollutants and contaminants from wastewater before it is discharged into the environment. IPAL plays a crucial role in maintaining the quality of water bodies and preventing pollution.

Eutrofikasi adalah proses alami atau buatan manusia di mana air menjadi kaya nutrisi seperti fosfor dan nitrogen. Ini menyebabkan pertumbuhan berlebihan alga dan tanaman air lainnya. Pertumbuhan alga yang berlebihan dapat menyebabkan penurunan kadar oksigen di air dan mengganggu ekosistem air. Hal ini dapat menyebabkan kematian burung dan mamalia air serta keracunan pada biota air.

Using excessive fertilizer can cause changes in the properties of the soil, which can have negative effects on plant growth. These changes may include increased acidity or alkalinity, altered nutrient levels, and reduced water retention capacity. These altered soil properties can hinder the availability of essential nutrients to plants, leading to stunted growth or even plant death. Therefore, it is important to use fertilizers in appropriate amounts to ensure optimal plant growth.

Kompos memiliki beberapa manfaat seperti menguatkan struktur lahan kritis, menjadi media tanaman, menggemburkan kembali tanah pertanian, dan mengurangi penggunaan pupuk kimia. Namun, menghambat bahan pencemaran bukanlah salah satu manfaat dari kompos.

The given options describe the impacts of water pollution. However, the option "Menurunkan BOD di perairan" (Decreasing BOD in water) does not describe a negative impact of water pollution. BOD stands for Biological Oxygen Demand, which is a measure of the amount of oxygen needed by microorganisms to decompose organic matter in water. A decrease in BOD indicates a decrease in organic pollution and can actually be considered a positive outcome in terms of water quality. Therefore, this option does not fit with the negative impacts of water pollution described in the other options.

Polusi tanah sebagian besar dihasilkan dari kegiatan pertanian. Aktivitas pertanian seperti penggunaan pestisida, pemupukan berlebihan, dan irigasi yang tidak efisien dapat menyebabkan pencemaran tanah. Selain itu, limbah pertanian seperti pupuk dan pestisida yang tidak terkelola dengan baik juga dapat mencemari tanah.

Suara yang bising dapat memicu emosi yang tidak stabil sehingga dapat menyebabkan hipertensi. Suara yang bising dapat meningkatkan tingkat stres dan kecemasan seseorang, yang pada gilirannya dapat meningkatkan tekanan darah. Jika tekanan darah terus-menerus tinggi, ini dapat menyebabkan hipertensi, yang merupakan kondisi medis serius yang dapat meningkatkan risiko penyakit jantung, stroke, dan masalah kesehatan lainnya.

The correct answer is "Kebisingan sementara" because it refers to the temporary noise that occurs at a specific time and within a certain period. This term implies that the noise is not constant or permanent, but rather occurs for a limited duration.

The given options are all benefits of recycling paper except for "Untuk membuat aneka kerajinan lain" which means "To make various other crafts". This option does not specifically mention the benefit of recycling paper but rather focuses on the use of recycled paper for crafting purposes. Therefore, it is not a direct benefit of recycling paper.

The benefit of using organic packaging is that it is easy to decompose. This means that the packaging can be broken down naturally and does not contribute to environmental pollution.

The correct answer is 2 and 5. The question asks for the environment with low noise levels. Options 2 and 5, which are "Rumah sakit" (hospitals) and "Tempat ibadah" (places of worship), are typically known for having quiet surroundings.

The main factors that need to be considered in pollution control are the characteristics of the pollution, the concentration of the released compounds in the environment, the geographical conditions of the pollution source, and the volatile solid content. However, the condition of the environment's meteorology is not a primary factor in pollution control. This means that while weather conditions may affect the spread or dispersion of pollutants, they are not one of the main factors that need to be controlled or managed in order to reduce pollution.
