Abstract

The purpose of writing this article is to understand the legal protection for people against the management of slaughterhouse waste in Indonesia. Animal slaughterhouse management waste is waste resulting from the cutting process and if not managed properly will have an impact on the surrounding environment. Pollution of animal slaughterhouse waste management can occur if not properly managed. The method of approaching research is normative juridical. The results of the study provide an answer that the protection of the law against the community is a fundamental thing to be accommodated by the surrounding government. Waste management is an absolute thing done by the state to ensure the good survival of the people in Indonesia. Keywords : legal protection, community, waste management, slaughterhouse

Abstract

Phytoremediation is an alternative technology for processing mercury (Hg) contaminated soil. The objective of this study was to treat Hg contaminated soil by adding compost using Sansevieria trifasciata and Celosia plumosa. The variations of the composition of the growth media were 100% contaminated soil and 80% contaminated soil with 20% compost. The plants used were aged 1 month and 30 cm high. The reactor was a polybag with a diameter and height of 25 cm. Sampling was conducted once every 7 days for 28 days. This research showed that the reactor with growth media consisting of 80% contaminated soil and 20% compost with Sansevieria trifasciata and Celosia plumosa had an Hg removal efficiency of 75.63% (58 mg/kg) and 66.81% (79 mg/kg), respectively. The Hg removal efficiency with growth media consisting of 100% contaminated soil was 74.79% (60 mg/kg) and 65.55% (82 mg/kg) in the reactor with Sansevieria trifasciata and Celosia plumosa respectively.

Abstract

Bioplastic is a plastic that can be decomposed because it can return to nature. This study aims to examine the optimal composition for the of bioplastics with various compositions of raw material. Comparison of the composition of waste banana peel:tapioca flour:glycerol, respectively 1:10:7,5 (sample A) and 1:13:11,25 (sample B). The ratio of the composition of waste rice:tapioca flour:glycerol in sample C and D is 1:10:7,5 and 1:13:11,25, respectively. Bioplastics are processed by using a composite of banana peel or rice waste which is dried to a moisture content of 70%. 30 mL of distilled water was added to the bioplastic and heated until thickened. The bioplastic is molded in a baking sheet while it is still hot and in an oven at 117˚C, then cooled at room temperature. The optimal composition of bioplastic is found in sample B with a biodegradation test value of 58% and contains bioplastics with functional groups O-H, C-H, C=O, C=C, C-O and =C-H in the FTIR test results. The quality standard values ​​for the tensile strength test and elongation test at break in sample B have values ​​of 10.9 MPa and 29%, respectively.

Abstract

he solid slaughter house waste (SSW) in Indonesia is generally disposed of into open dumped landfill. This type of solid waste can cause odor and atmospheric pollution if discharged directly into the environment. Additionally, it may spread disease due to the nesting vectors, and the resulting leachate can lead to groundwater contamination. This paper reviews the characterization of slaughter house (SH) types and SSW generation potential and to review the development of treatment technology of SSW and its application. The SH in Indonesia is divided into 3 classes, namely: 1) SH for large and small ruminants; 2) SH for poultry; 3) SH for pigs. Application technologies in Indonesia include compost and biogas technologies, and the use of rumen content for animal feed. Problem in biogas technology is generally caused by the high nitrogen content in the SSW. The most suitable raw material for biogas production is herbivore waste. The main advantages of using SSW for compost production are: the appropriate characteristics for composting process, free of hazardous contaminant, and appropriate composting technologies are available to reduce environmental problems caused by SSW. In addition, rumen content is considered to be a potential alternative for animal feed because have high content of amino acids (approximately 73.4% of the total protein) and rich in vitamin B complex. Among the disadvantages, the composting process of SSW requires long time period and generate air pollutants, such as ammonia and hydrogen sulphide.

Abstract

Soil is a very influential medium of human survival. One of the parameters affecting soil quality is heavy metal concentration in soil, especially heavy metal of lead (Pb). High concentrations of Pb in the soil can treated with phytoremediation techniques. The aims of this research are: 1. To investigate the reduction of heavy metal Pb in the soil by phytoremediation, 2. To investigate the effectiveness of plants to absorb heavy metal Pb in the soil, and 3. To investigate the distribution of Pb concentration in the plant parts. The study variables used in this research are species variation of plants Sansevieria trifasciata and Celosia pulmosa. Phytoremediation test of Pb heavy metal contaminated soil was carried out for 4 weeks with sampling time on days 0, 7, 14, 21, and 28. The parameters analyzed of this research is Pb concentrations on soil and plant parts, namely roots, stems, leaf. Physical observations of plants were also carried out to support this research. The results show that the reactor with Sansevieria trifasciata had a higher effectiveness of removal of Pb in 81.08% (112 mg/kg) than Celosia pulmosa in 59.63% (293 mg/kg). The effectiveness of the absorption of Sansevieria trifasciata was higher 70.50% (418 mg/kg) than Celosia pulmosa 52.40% (311 mg/kg). The distribution of Pb concentrations in the plant of Sansevieria trifasciata and Celosia pulmosa is almost the same, with the most concentration being in the root part and at least scattered in the leaves of the plant. Keywords: Celosia pulmosa, Soil, Lead, Phytoremediation, Sanseviera trifasciata.

Abstract

The purpose of the KKN-PPM activity is to make people aware of the importance of environmental conservation through groundwater conservation and empowering the people of Kalanganyar Village to build rainwater infiltration wells to help optimize water absorption. The output targets of the products produced in this program are: 1. Establishment of environmental cadres in the division of groundwater conservation as an effort to sustain the program, 2. Establishment of infiltration wells, and 3. Skills in maintaining infiltration wells. The method of implementation carried out is the preparation, debriefing and departure of KKN-PPM students, the development of appropriate technology (TTG), the implementation phase, and the assistance of environmentalcadres in the division of groundwater conservation. Conclusions from the KKN-PPM activities on groundwater conservation using infiltration wells in Kalanganyar Village, Sedati District, Sidoarjo Regency, East Java Province are: 1. The people of Kalanganyar Village have not used rainwater in the rainy season which caused rainwater runoff to flood and have limited water during the dry season, 2. Increasing knowledge of the people of Kalanganyar Village about environmental preservation and groundwater conservation using infiltration wells, 3. KKN-PPM Kalanganyar Village Sedati District Sidoarjo Regency provides a pilot in the form of infiltration wells in Kalanganyar Village to be used as a pilot for groundwater conservation in the village Kalanganyar.

Abstract

Usaha untuk mencegah penularan COVID 19 dapat dilakukan dengan menggunakan masker, menjaga jarak, mencuci tangan menggunakan sabun menggunakan handsanitizer dan lain sebagainya. Menjaga kesehatan tubuh agar terhindar dari COVID 19 salah satunya dengan menjaga imun tubuh dengan mengkonsumsi obat herbal/obat tradsional atau suplemen kesehatan. Kunyit, jahe, temulawak, meniran, jambu biji, sambiloto merupakan Tanaman obat keluarga (TOGA) yang berfungsi untuk meningkatkan imun. Tujuan dari kegiatan pengabdian pada masyarakat ini adalah pengetahuan tenatng pemanfaatan lahan pekarangan yang dapat dibuat sebagai taman TOGA. Metode pelaksanaan pengabdian diawali dari survey lokasi, penyuluhan dan monitoring serta evaluasi. Hasil dari kegiatan ini adalah masyarakat masyarakat memperoleh, pengetahuan dan kertampilan serta kesadaran untuk memanfaatkan lahan sebagai lahan tanaman TOGA. Hal itu ditandai dengan terlihatnya perubahan beberapa lahan warga yang sudah banyak ditanami tanaman TOGA dan mulai memanfaatkan hasilnya.
