Abstract

Penggunaan timbal (Pb) di industri dan penambangan semakin meningkat seiring dengan mening-katnya penambangan, peleburan, pembersih, dan berbagai industri. Suatu perairan yang telah terkontaminasi senyawa/ ion-ion Pb, sehingga jumlahnya dalam perairan melebihi konsentrasi yang semestinya dapat menga-kibatkan kematian bagi biota perairan. Fitoremediasi merupakan salah satu upaya mengreduksi cemaran Pb dari perairan dengan memanfaatkan tumbuhan. Hydrilla verticillata dan Najas indica merupakan tumbuhan air yang tergolong submerge yang banyak dijumpai di Sumatera Selatan. Penelitian ini dilakukan di Laborato-rium Riset Terpadu PascaSarjana Universitas Sriwijaya. Rancangan penelitian yang digunakan pada penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan pola faktorial dengan 2 faktor, yaitu macam jenis tanaman yaitu Hydrilla verticillata dan Najas indica, serta macam konsentrasi yaitu kontrol, 5 mg/l, 10 mg/l, 15 mg/l. Perlakuan ini dilakukan dengan 3 kali ulangan. Analisa kandungan Pb didalam tumbuhan dan di dalam air di-lakukan pada hari ke-5, hari ke-10, hari ke-15 dan hari ke-20 dengan metode analisa AAS yang dilakukan di di laboratorium penelitian Jurusan Kimia, Fakultas MIPA, Universitas Sriwijaya. Hasil yang diperoleh dari analisa laboratorium dilakukan Analisis Varian (ANAVA), jika berpengaruh nyata dilanjutkan dengan uji Duncans (DNMRT) pada taraf 5% dan dilakukan perhitungan kecepatan penyerapan Hydrilla verticillata dan Najas indi-ca. Hasil penelitian menunjukkan bahwa Hydrilla verticillata dan Najas indica memiliki kemampuan mereme-diasi timbal (Pb) dengan kandungan Pb dalam tumbuhan berbeda nyata pada perlakuan mulai B2. Hydrilla verticillata memiliki ketahanan lebih baik dalam mengakumulasi timbal (Pb) sampai hari ke-20 jika dibanding-kan Najas indica. Tetapi Najas indica memiliki kecepatan penyerapan lebih baik jika dibandingkan Hydrilla verticillata dengan waktu kontak optimum Hydrilla verticillata pada hari ke-20 dan waktu kontak optimum un-tuk Najas indica pada hari ke-15. Dengan demikian Hydrilla verticillata dan Najas indica memiliki potensi da-lam meremediasi timbal (Pb)

Abstract

Odonata are considered to be good indicators of enviromental health and water quality with it’s presence and diversity in the Jakabaring lake are (Water Ski and OPI). The research location (Water Ski and OPI) untilized by the community as water catchment areas (flood control), recreation and habitat. The Activity in the lake area can affect the benefit of the lake, affecting the quality of the lake waters as a living habitat for animals and plants.However, to describe the diversity of odonata as indicator of the waters in the area of Water Ski and Lake OPI lakes, there is no such thing, therefore the researchers to look at odonata diversity in the area of Water Ski Lake and Lake OPI Jakabaring Palembang-South Sumatera. The location of the study was determined using the purposive sampling method conducted in April 2018. The species found to identified at the FMIPA Animal Taxonomy Laboratory of Sriwijaya University. Sampling in the morning (07.00 – 10.00 AM) and afternoon (15.00 – 18.00 AM). The results of research in the lake area found 2 suborder, 2 families, 11 genere, and 18 species, the total number of all 984 individual species. Odonata species data obtained in the analysis using Past3 software. The diversity index in the Water Ski lake is 1.992 and the diversity index in the OPI lake is 1.758. Diversity index value (2.014), dominance index (0.7922) and evenness index (0.4165). Odonata and enviromental conditions of the lake (Water Ski and OPI) still have relationship, the condition of lake water quality is still below water quality criteria threshold. This is what makes the diversity on both lakes has a moderate value.

Abstract

Flavoparmelia caperata and Usnea dasypoga lichen for the first time was used to assess the concentration of heavy metals in the air in Palembang City. 5 heavy metals Cd, Cu, Pb, Fe, and Zn were measured using the transplant method. Both samples of lichen were collected from Gununghalu, Bandung. The lichen was transplanted at 7 points on the roadside, after 8 weeks, samples were collected and analyzed using SSA. The concentration of heavy metals accumulated in F. caperata was Fe> Cu> Zn> Pb> Cd, on U. dasypoga was Fe> Zn> Cu> Pb> Cd. The results showed that both types of lichen were very suitable to be used as an air quality bioindicator. The EC ratio of both transplanted samples showed higher levels of accumulation in U. dasypoga with a significant accumulation rate on Pb metal followed by Cu, Cd, Zn, and Fe. Furthermore, dendrogram showed clustering based on the concentrations of heavy metals accumulated at each station due to differences in density and vehicle type. This indicated that the metals have the same source which derived from emissions of motor vehicles, road construction activities, and other local anthropogenic activities.

Abstract

To simplify the description of the damage phenomenon to the earth, the concept of ecological footprint can be used. This concept is not specifically built to calculate the destruction of the earth. This concept calculates how much space (land and water) humans need to produce the resources they need including absorbing the waste they produce. This study calculates Indonesia's ecological footprint by observing variations according to geography and the level of regional government. This research uses the Environmental Care Behavior Survey Year 2013, Village Potential Census Year 2011 and the 2013 National Social Welfare Survey, or SUSENAS. All were surveyed by the Indonesian Central Bureau of Statistics. As a result, Indonesia's ecological footprint is 1.51 gha. At the provincial level, the ecological footprint of Jakarta is the highest compared to other provinces’ of 1.84 gha. While East Nusa Tenggara has the lowest ecological footprint, which is 1.30 gha. Indonesia's ecological footprint follows the general pattern in the world, of higher ecological footprint in urban area compared to other types of regions such as villages, watersheds, beaches, mountains, forests or hilly areas.

Abstract

To simplify the description of the damage phenomenon to the earth, the concept of ecological footprint can be used. This concept is not specifically built to calculate the destruction of the earth. This concept calculates how much space (on land and water) humans need to produce the resources they need including absorbing the waste they produce. This study calculates the ecological footprint in Palembang and its surroundings according to demographic factors and local government.  To investigate the general pattern of ecological footprint and its determinants based on the respondents’ reports, a survey was launched in October 2017. As a result, the average ecological footprint in Palembang Metropolitan and its surroundings is 0.591 global hectares (gha).  The ecological footprint in Palembang Metropolitan and its surroundings is formed by 4 things, namely: diet and food choices, shelter/home life, transportation and lifestyle choices.  The largest portion is given by diet and food choices (26.8 percent), while the smallest contribution is contributed by transportation (24.1 percent).   Taking into account demographic factors, a high ecological footprint is owned by a group of male individuals, aged 30-39 years, highly educated, working, and after hearing and understanding climate change and ecological footprint. Finally, if observed according to the type of government, metropolitan cities have a high ecological footprint than others.  Finally, the ecological footprint of Palembang as a metropolitan city is higher than the others.
