Eco Enzyme is a result of organic waste fermentation, derived from leftover fruits, vegetables, sugar, and water. It was first discovered by Dr. Rosukon Poompanvong, a member of the Organic Farming Association from Thailand. Eco Enzyme serves as a versatile liquid for household, agricultural, and livestock purposes. According to an article by Vama & Chekar in 2020, eco enzyme can be utilized as an antifungal, antibacterial, insecticide agent, and cleaner. Some of its functions include being a floor cleaner, dish cleaner, and toilet cleaner.The author created a business around eco enzyme using leftover fruits. The raw materials for eco enzyme are obtained from fruits that are no longer consumable or have become spoiled. Although there have been numerous studies on utilizing leftover fruits for eco enzyme production, not many people in the community are aware of or use eco enzyme. Therefore, the author came up with the idea of a business centered around eco enzyme, both as a value proposition for utilizing leftover fruits and as a means to educate people who are unfamiliar with eco enzyme.

Organic fertilizers are materials derived from plant residues, and animal waste, both those that have undergone decomposition and those that are undergoing a decomposition process that functions to add nutrients. Substantially organic fertilizers are composed of humus and non-humus materials so that they can improve marginal soils and sand-dominated soils. The purpose of this study was to determine the effect of various organic fertilizers on sand planting media, and to determine the growth response of pakcoy on various types of organic fertilizers. The research was conducted at the Field Laboratory I Experimental Garden and Agrotechnology Laboratory of the Faculty of Agriculture, Halu Oleo University, the research took place from September to November 2020. This study was arranged in a randomized group design (RAK) with the treatment of various organic fertilizers, which were divided into; no organic fertilizer/control (B0), cow manure (B1), chicken manure (B2), comba-sheep green manure (B3), calopogonium green manure (B4). Each treatment was repeated four times as a group, resulting in 20 experimental units. Each experimental unit consisted of six polybags, resulting in a total of 120 polybags of pakcoy plants. The variables observed were plant height, number of leaves, fresh weight and dry weight of pakcoy plants. The results showed that organic fertilizer had a very significant effect on all observed growth variables of pakcoy plants. Cow manure treatment in the first and second week plant height variables showed the highest value (5.04 cm, and 6.71 cm). But in general, in the third to fifth week, the average chicken manure gave the highest growth response on the variable of plant height, number of leaves, fresh weight and dry weight of pakcoy plants.

Indonesia, Indonesia is a nation of law that uses a rule of law country (rechtstaat) concept. The concept of rule of law Indonesia set forth in its Constitution, the 1945 Constitution, Article 1 paragraph (3). There is an important element of democracy stated on the Constitution, namely the protection of human rights, that every citizen has the right to enjoy it. One of the rights protected in the Constitution is right to access a good and healthy living environment. For this, the environment needs to be preserved and function through administrative law enforcement. The study uses normative juridical approach with descriptive-analytics, which describes the norms and associated with theories, and opinions of legal experts. The development of a democratic nations of law can be seen from the aspect of law enforcement in particular with environmental administration. In Indonesia, it can be reviewed through the theory of organic states and the theory of pluralist states. Based on the theory of an organic state and looking at the aspects of environmental administration law enforcement in Indonesia, the state has regulated the enforcement of environmental administrative sanctions whereby the state can regulate every activity and/or business in the environmental issues. Therefore, the pluralist state theory recognized a variety of diverse interests in society that the state has accommodated all citizens rights to a good and healthy environment through pro-environment government policies

Efforts to increase income, provide employment, contribute to the availability of animal protein and increase production activities are part of food security in the aquaculture sector. Based on data reported from the DGT KKP Statistics, (2021) aquaculture can increase production activities, where in 2020 the third quarter of fish farming production reached 11.5 million tons and increased to 12.25 million tons in 2021 in the third quarter.  Alternative techniques that can be done as an effort to increase fish farming production results are optimizing the use of biofloc system technology (Pramono et al., 2018; Faridah et al., 2019 and Permana et al., 2021). This biofloc system is a union of living organic substances into the form of blobs, where this biofloc is composed of the word bio which means life while floc means blob. For example, in tilapia farming, to increase production results so that they can ... Meeting market demand can implement a biofloc system. Tilapia is classified as a type of freshwater fish that is in great demand in the market. The advantages of implementing a biofloc system in tilapia farming are environmentally friendly so that it is easy to carry out advanced cultivation, there is efficiency in water utilization, short maintenance period, and maximizing stocking density. In addition to the advantages, there are also obstacles faced, fish farming with a biofloc system such as lack of understanding of fish farming with the biofloc method, directly providing feed without paying attention and lack of water quality control. Furthermore, the research conducted implemented the observational descriptive method. 

The high number of stunting cases in Indonesia is in the spotlight of WHO, so that stunting cases are given serious attention by the government by making preventing and reducing the number of stunting cases a national program through the collaboration of several ministries. Based on this, the government launched food estates as a national strategic program for 2020-2024. It is hoped that this program will be a solution to overcome the high number of stunting cases while reducing the number of stunting cases that have been found. The food estate program approach, which is expected to have an impact on reducing and preventing stunting cases, uses the "zero waste furming system" method, namely the use of corn and oil palm plantations that have developed so far as beef cattle farms where corn and plantation waste are processed into animal feed. and livestock manure and urine are processed into biogas and organic fertilizer which are really needed by corn and oil palm plants. The intervention program to reduce and prevent stunting rates in Central Mamuju Regency is carried out comprehensively through a food security program (food estate) and providing additional nutrition and other nutritional needs, especially for community groups who are vulnerable to nutritional and protein deficiencies.

Shallot is a horticultural commodity that has good market prospects because it contains high nutrition and can be used as spices and ingredients for traditional medicine. However, shallot production in Indonesia still often fluctuates and even experiences a shortage in meeting the needs of domestic consumers. To increase shallot production, this can be done through intensification efforts, namely by improving cultivation techniques, such as the use of organic fertilizers, proper fertilization, and the use of superior varieties. This study used a factorial randomized block design consisting of 2 treatment factors, namely factor I, fermented NPK ( F) consisting of 0 ml, 250 ml, 500 ml and 750 ml. Factor II was the variety (V) of the Brebes Bima variety, the Probolinggo variety and the Nganjuk variety. The parameters of plant observation were: plant height (cm) and production per plot (g). The data analysis method was a factorial randomized block design (RBD). The results showed that the application of fermented NPK and the use of varieties had a very significant effect on the parameters of plant height (cm) and production per plot (g).

Penambangan yang dilakukan di Indonesia adalah penambangan emas skala kecil, yang sering disebut dengan istilah PETI (Penambangan Emas Tanpa Izin). Kegitan ini biasanya menggunakan metode amalgasi dengan merkuri (Hg) untuk mendapatkan biji emas. .Merkuri (Hg) merupakan salah satu unsur yang paling beracun dari logam berat yang ada dan apabila terpapar pada konsentrasi yang tinggi maka mengakibatkan kerusakan otak secara permanen dan kerusakan ginjal. Di dalam air, logam merkuri dapat mengalami biotransformasi menjadi senyawa organik metil merkuri atau fenil merkuri akibat proses dekomposisi oleh bakteri. Senyawa organic tersebut diserap oleh jasa renik yang akan masuk dalam rantai makanan. Ini akhirnya tejadi akumulasi dan biomagnifikasi merkuri dalam tubuh biota laut seperti ikan, udang dan kerang yang pada akhirnya masuk kedalam tubuh manusia yang mengkonsumsinya. Penelitian ini menggunakan metode Mercury Analyzer yang dilakukan pada sampel ikan yang berbeda pada titik pengambilan yang berbeda pula untuk melihat ada tidaknya pencemaran merkuri di lingkungan pertambangan. Penelitian ini dilakukan di Kecamatan Teluk Kaiely Kabupaten Buru. Hasil penelitian ini menujukan bahwa 2 dari 3 sampel dinyatakan terkandung merkuri dengan kadar pada sampel di Kaiely ikan Kerong – Kerong (Terapon jarbua F.) sebesar 0,001 mg/L dan sampel di Kaki Air dengan ikan Pilchard Eropa (Sardina Pilchardus) sebesar 0,0003 mg/L. Sampel di Seith ikan Layang Biru (Decapterus macarellus) sebesar 0,00 mg/L atau tidak terdeteksi merkuri. Hasil ini menunjukan bahwa ikan masih layak dikonsumsi manusia karena dibawah baku mutu batas kandungan merkuri pada ikan yang dikonsumsi manusia yaitu sebesar 0,5 mg/kg
