Abstract

ABSTRAKKegiatan antropogenik secara intensif mengakibatkan pencemaran lingkungan yang disebabkan oleh logam berat. Timbal (Pb) merupakan salah satu logam berat toksik. Tingkat toksisitas dapat diturunkan melalui proses bioakumulasi oleh mikroorganisme. Penelitian ini dilakukan untuk mengetahui kemampuan bakteri Streptomyves sp. strain I18 dalam mengakumulasi logam Pb. Bakteri diidentifikasi morfologi secara makroskopik dan mikroskopik. Daya resistensi bakteri terhadap logam Pb ditentukan dengan menumbuhkan bakteri pada media Muller-Hilton Agar yang disuplementasi Pb pada konsentrasi 5, 50, dan 150 ppm menggunakan metode dilusi pada cawan petri petri. Bioakumulasi bakteri terhadap logam Pb diukur menggunakan Atomic Absorption Spectroscopy (AAS) pada konsentrasi 5, 50, dan 150 ppm. Bakteri Streptomyves sp. strain I18 mampu tumbuh pada media padat agar mengandung logam Pb pada bagai konsentrasi dengan diameter koloni terbesar, yakni 50.33 mm pada konsentrasi Pb 5 ppm. Pertumbuhan koloni terkecil sebesar 33.00 mm terjadi pada konsentrasi 150 ppm. Bakteri ini terbukti mampu mengakumulasi logam Pb dengan akumulasi terbesar pada konsentrasi 5 ppm, sebesar 49%. Peningkatan konsentrasi logam menurunkan kemampuan akumulasi logam Pb. Pada konsentrasi 150 ppm dan 50 ppm, bakteri hanya mampu mengakumulasi Pb sebesar 5% dan 9%. Kemampuan optimal bakteri Streptomyves sp. strain I18 sebagai bioakumulator diperkirakan pada konsentrasi kurang dari 50 ppm.Kata kunci: bioakumulasi, Pb, resistensi, Streptomyces ABSTRACTAntropogenic activity intensively can cause environmental pollution by heavy metals.

Abstract

ABSTRAK Pertumbuhan penduduk Kota Bogor sangat tinggi, sehingga terjadi peningkatan sampah yang tidak terkelola dengan baik. Pengelolaan sampah seperti tempat penampungan sementara pemerintah belum mampu memenuhi kebutuhan masyarakat, yang mengarah pada munculnya LPS (Lokasi Pembuangan Sampah) ilegal akibat praktik pembuangan sampah ilegal oleh masyarakat setempat. Bahaya LPS ilegal adalah dapat mencemari lingkungan, berpotensi menyebarkan penyakit dan menghilangkan nilai estetika di daerah tersebut. Penelitian ini bertujuan untuk memetakan dan menganalisis penyebaran situs LPS ilegal dengan faktor-faktor yang berpengaruh. Data penelitian diambil langsung dengan observasi dan pengukuran di lokasi tersebut dan dengan bantuan studi perpustakaan. Hasil penelitian kami menunjukkan ada 6 kecamatan yang menjadi objek penelitian di Kota Bogor, antara lain Bogor Utara, Bogor Barat, Bogor Tengah, Tanah Sareal, Bogor Timur, Bogor Selatan. Hasil penelitian ini menemukan 28 lokasi LPS ilegal yang tersebar di 6 kecamatan. Sebaran dipengaruhi oleh kepadatan penduduk, lahan, jarak ke sungai, jenis jalan dan ketersediaan TPS (Tempat Pemrosesan Sampah) legal.Kata kunci: Kota Bogor, LPS ilegal, pemetaan, sistem informasi geografi ABSTRACT The population growth of Bogor city is very high, so there is an increase in waste that is not managed properly. Although waste management facilities such as temporary shelters have not been able to meet the needs of the community, which leads to the emergence of illegal garbage disposal location due to illegal waste disposal practices by the local community. The danger of illegal garbage disposal location is that it can pollute the environment, potentially spreading disease and eliminating aesthetic value in the area. This study aims to map and analyze the spread of illegal garbage disposal location sites with influential factors. The research data was taken directly with observation and measurement at the site and with the help of library studies. The results of my research showed that there are 6 sub-districts that are the object of research in Bogor City, including North Bogor, West Bogor, Central Bogor, Tanah Sareal, East Bogor, South Bogor. The results of this study found 28 illegal garbage disposal locations spread across 6 sub-districts. Furthermore, the distribution is influenced by population density, land, distance to the river, type of road and availability of legal Garbage Processing Site.Keywords:  Bogor City, illegal garbage disposal location, mapping, geographic information system

Abstract

ABSTRAKCacing tanah atau Lumbricus rubellus adalah salah satu cacing yang banyak dibudidayakan di Indonesia. Cacing ini memiliki karakteristik hidup yang mudah, cepat berkembangbiak dengan ciri - ciri panjang tubuh 8 cm–14 cm. Oleh karena itu, cacing ini banyak dibudidayakan karena dapat diolah menjadi berbagai macam produk seperti probiotik pakan ternak. Probiotik berbahan cacing memiliki kandungan protein yang sangat tinggi sebesar 64-76%, serat kasar 45% dan kandungan lainnya yang dapat bermanfaat untuk kesehatan ternak. Pemanasan secara konvensional sebelum proses fermentasi secara tidak langsung menurunkan kandungan protein pada cacing tanah. Oleh karena itu, penggunaan teknologi pulsed electric field (PEF) pada penelitian ini bertujuan untuk menjaga stabilitas protein sekaligus mengurangi kontaminasi produk fermentasi. Penelitian ini menggunakan metode Rancangan Acak Lengkap dengan dua faktor, suhu dan waktu pemberian PEF yang diberikan sebelum bahan diproses. Sedangkan pemilihan perlakuan terbaik menggunakan metode Multiple Attribute Zeleny. Hasil penelitian menunjukkan bahwa suhu dan waktu pretreatment PEF, berpengaruh nyata terhadap pH, namun tidak berpengaruh nyata terhadap warna pada probiotik pakan ternak dari cacing tanah. Perlakuan terbaik terdapat pada pretreatment pada suhu 270C dan waktu 30 detik dengan nilai pH sebesar 4.8 dan nilai warna untuk tingkat kecerahan (L*) sebesar 4.8, tingkat kemerahan (a) sebesar 40.90 dan tingkat kekuningan (b) sebesar 2.12.Kata kunci: cacing tanah, pulsed electric field, probiotik, pH, warna ABSTRACTEarthworm or Lumbricus rubellus is one of the worms that are widely cultivated in Indonesia. Lumbricus rubellus has the characteristics of an easy life, fast breeding with characteristics of a body length of 8 cm-14 cm. Therefore, Lumbricus rubellus is widely cultivated since it can be processed into various products such as animal feed probiotics. Probiotics made from worms have a very high protein content of 64-76%, crude fiber 45% and other ingredients that can be beneficial for livestock health. The conventional heating before the fermentation process indirectly reduces the protein content of earthworms. Therefore, the use of pulsed electric field (PEF) technology in this study aims to maintain protein stability and reducing product contamination. This study used a completely randomized design method with two factors, temperature and time of PEF exposure. While the selection of the best treatment using the Multiple Attribute Zeleny. The results showed that the PEF pretreatment had a significant effect on pH, but did not significantly affect the color of animal feed probiotics from earthworms. The best treatment was found at a temperature of 27oC and a PEF time of 30 seconds with a pH value of 4.8 and a color value for the brightness level (L*) of 4.8, the level of redness (a) of 40.90 and the level of yellowness (b) of 2.12.Keywords: earthworms, pulse electric field, probiotic, pH, color

Abstract

ABSTRAK Meningkatnya jumlah penduduk, pertumbuhan ekonomi dan adanya perubahan pola konsumsi masyarakat berbanding lurus dengan jumlah, jenis dan karakteristik sampah. Sampah adalah produk dari aktivitas manusia yang berkontribusi pada pemanasan global. Salah satu upaya Indonesia dalam mengurangi emisi gas rumah kaca untuk mengurangi dampak perubahan iklim pada sektor pengelolaan sampah dengan mendirikan  program Tempat Pengolahan  Sampah Terpadu (TPST)  dengan menggunakan prinsip 3R (reduce, reuse, recycle). Penelitian ini bertujuan menghitung potensi tapak karbon penyumbang emisi GRK dari timbulan sampah, mengetahui kondisi eksisting dan menganalisis pengaruh TPST 3R Mulyoagung Bersatu terhadap pengurangan emisi GRK. Gas rumah kaca dalam penelitian ini dibatasi pada gas metana (CH4). Perhitungan emisi GRK pada penelitian  mengacu pada rumus Tier-1 IPCC (Intergovernmental Panel on Climate Change). Perhitungan emisi GRK emisi metana (CH4) berdasarkan dari 2 skenario yang ditentukan. Skenario 1 menghasilkan emisi (CH4) 45,900 Ton CO2eq/tahun. Skenario 2 menghasilkan emisi sebesar 9,180 Ton CO2eq/tahun. Persentase emisi (CH4) yang terreduksi dari aktivitas TPST 3R  80%. Perhitungan uji korelasi sederhana didapatkan  hubungan yang linier (berbanding lurus) dengan nilai koefisien korelasi bernilai positif (r= 1) hubungan keeratan sangat kuat. Hal tersebut menunjukan dengan adanya TPST mampu mereduksi emisi (CH4) dari total sampah yang akan ditimbun secara langsung di TPA Randuagung.Kata kunci: gas metana (CH4), gas rumah kaca, tapak karbon, TPST 3R ABSTRACT The increasing population, economic growth and changes in people's consumption patterns are directly proportional to the amount, type and characteristics of waste. Garbage is a product of human activities that contribute to global warming. One of Indonesia's efforts to reduce greenhouse gas emissions is to reduce the impact of climate change on the waste management sector by establishing the Integrated Waste Processing Site (TPST) program using the 3R principle (reduce, reuse, recycle). This study aims to calculate the potential carbon footprint that contributes to GRK emissions from waste generation, to determine the existing conditions and to analyze the effect of TPST 3R Mulyoagung Bersatu on GRK emission reduction. The greenhouse gas in this study was limited to methane (CH4). Calculation of GRK emissions in the study refers to the IPCC Tier-1 (Intergovernmental Panel on Climate Change) formula. Calculation of GRK emissions of methane (CH4) emissions based on 2 specified scenarios. Scenario 1 produces 45,900 Ton CO2eq/year (CH4) emissions. Scenario 2 produces emissions of 9,180 tons CO2eq/year. The percentage of emission (CH4) reduced from TPST 3R activity is 80%. Calculation of simple correlation test obtained a linear relationship (directly proportional) with a positive correlation coefficient value (r = 0.999) very strong close relationship. This shows that the presence of TPST is able to reduce emissions (CH4) from the total waste that will be dumped directly at the Randuagung TPA.Keywords:  methane gas (CH4), greenhouse gas, carbon footprint, TPST 3R

Abstract

ABSTRACT Tanggulangin Cultural Park is a new facility provided by the local government as a recreational facility for residents. Along the way, many people use the area to boost the economy, by selling food, drinks, and so on. So it can be ascertained that water is a material that is used every day. Many residents use water from the Tanggulangin Cultural Park area for the production process of food, beverages, and other purposes, so it is necessary to know the water quality in the park, physically, chemically, and microbiologically. This research was conducted in October-November 2021 by testing the parameters of temperature, turbidity, pH, water hardness, and total coliform. The results obtained are water temperatures of 34.6 and 31.6oC, turbidity of 2.87 NTU and 3.08 NTU, pH of 7.08 and 6.92, water hardness of 1.28 mg.L-1 and 1.32 mg.L-1, and total coliforms of 7.8 CFU/100 ml and 6.8 CFU/100 ml. In general, all these parameters are still below the standard of the Regulation of the Minister of Health of the Republic of Indonesia. No. 32 of 2017. However, attention must be paid to the presence of total coliform content in water.Keywords: water quality, physical, chemical, microbiological
