Abstract

Kegiatan industri di Kabupaten Cilacap seperti pembangkit listrik tenaga uap dan proses kilang minyak bumi yang mayoritas menggunakan batu bara sebagai bahan bakar berpotensi menyumbang limbah padat yang mengandung logam berat seperti timbal (Pb). Penelitian yang dilakukan bertujuan untuk mengetahui biokonsentrasi faktor logam timbal pada ikan tongkol, tuna dan kembung di Pantai Kemiren, Cilacap, Jawa Tengah. Sampel air diambil sebanyak 2 liter pada 3 titik lokasi daerah perairan pasang surut Pantai Kemiren. Sampel ikan berupa hasil tangkapan ikan yang terdiri dari 3 jenis ikan konsumsi di TPI Pantai Kemiren, Cilacap. Sampel air dan ikan dianalisis kadar Pb nya dengan Spektroskopi Serapan Atom. Hasil penelitian ini menemukan bahwa air laut di Pantai Kemiren telah mengalami pencemaran timbal dengan konsentrasi rata-rata sebesar 0,213 ppm. Konsentrasi rata-rata logam berat Pb dalam sampel ikan tongkol, tuna dan kembung di TPI Pantai Kemiren berturut-turut adalah 1,585 ppm, 1,561 ppm, dan 0,978 ppm yang memiliki konsentrasi yang cukup tinggi dan melebihi baku mutunya. Nilai biokonsentrasi faktor logam Pb dalam ikan di TPI Pantai Kemiren mengalami penurunan dengan urutan ikan tuna > ikan tongkol > ikan kembung, dimana hasil ketiganya masuk dalam kategori akumulasi rendah.

Abstract

The number of Micro, Small and Medium Enterprises (MSMEs) in Indonesia as of September 2021 reached 64.2 million by contributing a GDP of around 61.07 percent and being able to absorb 97% of the total existing workforce, and was able to collect 60.42% of the total investment in Indonesia. This indicates that MSMEs have great potential to be developed, besides that MSMEs also contribute gross domestic product (GDP) in Indonesia, open opportunities to empower family finances, open business opportunities and absorb labor which in turn can improve the economy in Indonesia. However, the last two, the whole world has experienced economic paralysis caused by the Covid-19 pandemic outbreak, as well as what happened in Indonesia. One of them has experienced a bad impact on MSMEs/ MSEs. The product of various chips "Tunggal Makmur" is a household industry that still survives today even though with Covid-19, production has decreased by up to 50% during the Covid-19 pandemic. For the conditions mentioned above, the Cilacap State Polytechnic Lecturer intends to carry out Community Service (PKM) at the location of various chips in Widarapayung Wetan village, Cilacap Regency. Community service aims to provide information and knowledge coaching to increase understanding of the important role of business in packaging various chips to attract buyers. The method used in this activity is by surveying methods and directly involving spaciousness to conduct coaching and conducting questions and answers with participants. What is expected by guiding to increase understanding of information and knowledge and socialization is to be able to increase sales by providing attractive packaging and labels. The output will be produced in the form of videos and journals.

Abstract

Population growth and settlements have significant consequences on basic problems. One of the main problems that arises and needs to be planned is waste problem. Large amount of unhandling landfill causes various problems, both directly and indirectly for the city population, especially the community members in Desa Maos Lor, Dusun Tengah RW 11 who own a Waste Bank. The problem from Waste Bank is the organic waste that is not utilized and managed optimally, instead it is allowed to accumulate and rot, so it pollutes the environment. The potential method for handling organic waste is by applying anaerobic composter technology to produce fertilizer or compost, which is a swing composter. The composition in the swing composter consists of husk as the base, compost as the starter, fine organic waste (in the form of residual waste or kitchen waste), then it is covered with husk. To speed up the occurrence of decay, the kitchen waste is chopped into small size. Then, the composter is swung 5 to 10 times for mixing it with microorganisms. Next step is letting the swing composter for 4 months. Liquid organic fertilizer and solid organic fertilizer can be used by residents of Desa Maos Lor Dusun Tengah RW 11 to grow crops.

Abstract

Recycling plastic waste, especially Polyethylene Terephtalate (PET), into plastic pellets has great potential for producing environmentally friendly products. This study aims to recycle plastic waste from used mineral water bottles into plastic pellets using the pelletizing method, or the process of molding a material into pellets, with the independent variables being the brand of PET plastic bottle waste and temperature, and to determine their effect on the quality of the recycled plastic pellets produced. The quality parameters tested included moisture content, bulk density, total heavy metals Pb, PVC contamination, other contaminants, tensile strength, shape, color, and toxicity (LC50). The results showed that all parameters met the SNI 8424:2017 quality standards and had a fairly uniform color in the V120 variable, while in V135, only PVC contamination did not meet the standards, but for both variations, the shape was not uniform. The 72-hour LC50 test on all variations with a concentration of 6.5 kg/m3 showed low toxicity as it resulted in zero fish mortality.
