Abstract

ABSTRAK Rumah tangga dengan segala aktifitasnya turut menyumbang emisi CO2 yang memicu pemanasan global. Oleh karena itu, berdasarkan prinsip pencemar membayar (pollutant pay principle), rumah tangga dapat dikenai tanggung jawab atas emisi yang dihasilkan dalam bentuk konservasi lahan. Penelitian bertujuan menganalisis rata-rata emisi dan rata-rata sequestrasi, untuk menetukan luas minimum lahan yang harus dikonservasi masing-masing kelompok rumah tangga Kelas Ekonomi Atas (KEA- Daya ≥ 1300 VA), Kelas Ekonomi Menengah (KEM- Daya 900 VA), Kelas Ekonomi Bawah (KEA- Daya 450 VA) di Desa Sinduadi, Kecamatan Mlati, Kabupaten Sleman, D. I. Yogyakarta. Emisi CO2 dihitung berdasarkan aktifitas rumah tangga terkait konsumsi listrik, konsumsi bahan bakar untuk transportasi, konsumsi bahan bakar untuk memasak, produksi sampah, serta konsumsi air PDAM, didapat dari hasil questioner yang selanjutnya dikalikan dengan nilai konversi emisi CO2 yang tersesedia. Sequestrasi CO2 dihitung berdasarkan biomassa yang dipertahankan oleh rumah tangga pada lahan bervegetasi mereka (pekarangan, sawah, kebun). Pendugaan biomassa diperoleh melalui metode Brown (1997) dan Hairiah (2007), dengan melakukan nested qudrat sampling pada masing-masing jenis lahan bervegetasi yang dimiliki rumah tangga. Luas minimum dan optimalisasi lahan, dihitung berdasarkan jumlah emisi CO2 rumah tangga dan biomassa per m2 lahan. Berdasarkan hasil penelitian diketahui, rumah tangga Sinduadi memiliki rata-rata emisi dan sequestrasi, serta luas minimum lahan secara berturut-turut sebesar: 7098,98 kgCO2/th, 267,34 kgCO2/th, dan 178,11 m2 dengan tingkat optimalisasi lahan sangat optimal (tutupan vegetasi 90%) pada lahan pekarangan untuk rumah tangga KEA; 3785,9 kgCO2/th, 632,61 kgCO2/th, dan 1551,37 m2 lahan pekarangan dengan dengan tingkat optimalisasi lahan sangat optimal (tutupan vegetasi 90%) pada lahan pekarangan untuk rumah tangga KEM; 1973,3 kgCO2/th, 780,21 kgCO2/th, dan 898,91 m2 dengan tingkat optimalisasi lahan sangat optimal (tutupan vegetasi 90%) pada lahan pekarangan untuk rumah tangga KEB. ABSTRACT Households with all its activities contributed to CO2 emissions that lead to global warming. Therefore, based on the polluter pays principle (pollutant pay principle), households may be held responsible for the emissions produced in the form of land conservation. The study aims to analyze the average emissions and the average sequestration, to determine the minimum area of land to be conserved each household group Economy Class Upper (Power KEA- ≥ 1300 VA), Economy Class Intermediate (back Power 900 VA), Down Economy Class (KEA- Power 450 VA) in the village of Sinduadi, Mlati subdistrict, Sleman, Yogyakarta. CO2 emissions are calculated based on household activities related to electricity consumption, fuel consumption for transportation, fuel consumption for cooking, waste production and water consumption taps, obtained from the questionnaire were subsequently multiplied by the conversion of CO2 emissions tersesedia. CO2 sequestration is calculated based biomass is retained by households on their vegetated land (yards, fields, gardens). Biomass estimation obtained through the method of Brown (1997) and Hairiah (2007), by nested qudrat sampling on each type of vegetated land owned by households. And the minimum area of land optimization, CO2 emissions are calculated based on the number of households and biomass per m2 of land. Based on the survey results revealed, households had an average Sinduadi emissions and sequestration, and the minimum area of land consecutively for: 7098.98 kgCO2 / th, 267.34 kgCO2 / th, and 178.11 m2 with a very level land optimization optimal (vegetation cover 90%) in their yards for household KEA; 3785.9 kgCO2 / th, 632.61 kgCO2 / th, and 1551.37 m2 yard area with the optimization level is optimal land (vegetation cover 90%) in their yards for household KEM; 1973.3 kgCO2 / th, 780.21 kgCO2 / th, and 898.91 m2 with very optimal level of optimization of land (vegetation cover 90%) in their yards for household KEB.

Abstract

The terminal in Bojonegoro District is Rajekwesi Type A Terminal. It is located close to the CBD that has resulted in a decrease in environmental quality, due to gas emissions released by motor vehicles. The decrease in environmental quality can be overcome with an ecological approach, for example by creating or expanding green open spaces (urban forest). This study aimed to provide information about the capability of urban forest of the terminal to absorb CO2 emissions. This study began with a survey counting the number of motor vehicles at the gateway of the terminal on Sunday, Monday, Wednesday, Friday and Saturday for 24 hours. Then, the measurement of tree biomass was carried out using the nondestructive method. After the data was collected, the amount of CO2 emissions from motor vehicles was calculated by adding up CO2 emissionsin a stationary (idle) position when it was moving. The total CO2 emissions of motor vehicles at Rajekwesi Type A Terminal was 292.058,087 kgCO2/year. The amount of carbon sink (Wtc) of a tree was calculated by multiplying the total biomass (Wt) by the carbon concentration. The amount of Wtc at the urban forest of Rajekwesi Type A Terminal was 4.366,059 kg/year. After the amount of Wtc was found out, the amount of CO2 absorbed by the tree could be found out by multiplying Wtc by the conversion constant of the carbon (C) element to CO2 (3,67). The amount of CO2 absorbed by the trees at the urban forest of Rajekwesi Type A Terminal was 16.023,44 kgCO2/year. If they were compared, the absorption of CO2 was still much smaller than the emission rate. Thus, the function of the urban forest of terminal as an absorber of CO2 emissions was still not optimal.

Abstract

Many studies declared traditional oil mining in Wonocolo caused pollution, including river pollution.  During Covid-19 Pandemic, traditional oil mining in Wonocolo has been interrupted because world oil prices decreased. This made selling price of crude oil in Wonocolo declined. This made traditional oil mining decreased because oil wells were temporarily closed. The decrease in traditional oil mining might affect river water quality in Wonocolo. In a prior  study, the researcher had investigated water quality of Bungsu and Kragsaan River in Wonocolo, based on physicochemical parameters. The river had improved quality during Covid-19 Pandemic, seen from the decrease in the content of several chemical pollutants. Through this study, the researcher examined macrozoobentos community structure as a bio indicator of water quality, like assessing water quality of Bungsu and Kragsaan River based on biological indicators. This study used observation method by determining sample points purposively. Sample of macrozoobentos was analyzed using biodiversity index of Shannon-Wiener, species evennes index, and dominance index. Results of study showed Bungsu River had low biodiversity (H’ index 0.000 – 1.040), distressed community at B-1 and B-3 but stable at B-2, like high dominance at B-1 and B-3 but low at B-2. Kragsaan River also had low biodiversity (H’ index 0.000 – 1.010), unstable community at K-1 and K-3 like distressed at K-2, and low dominance at K-2 and K-3 but medium at K-1. Based on H’ index, Bungsu River was in the heavily polluted category at B-1 and B-3 and the medium polluted category at B-2. Meanwhile, Kragsaan River was in the heavily polluted category at K-1 and K-2 and the medium polluted category at K-3. This means although decreased levels of chemical pollutants at the sampling locations meant an increase in quality of water body, river ecosystem had not been able to rejuvenate condition during Covid-19 Pandemic.

Abstract

Tradisi ngasak telah berkembang sejak zaman dahulu, khususnya di Pulau Jawa, termasuk salah satunya di Kabupaten Bojonegoro. Penelitian Nurani L.S. (2012) menyebutkan bahwa ibu yang memiliki anak kelahiran tahun 1920 telah mengajarkan anak perempuan mereka untuk ngasak jika sawah yang mereka miliki belum panen. Faktor kehilangan gabah saat ini hanya dihitung berdasarkan faktor internal saja, sedangkan faktor eksternal yaitu faktor luar yang tidak berkaitan langsung dengan proses pemanenan, termasuk di dalamnya factor tradisi ngasak, belum dipertimbangkan. Tujuan penelitian ini adalah menghitung potensi kehilangan gabah pada tahap pemanenan di setiap hektar lahan akibat aktivitas ngasak. Penelitian ini menggunakan Metode Survey Analitis yang merupakan metode investigasi dalam pengumpulan data, dimana data yang dikumpulkan merupakan data kuantitatif yang membutuhkan analisis statistik. Penghitungan kehilangan gabah dilakukan dengan menghitung rerata jumlah pengasak dikalikan rerata hasil ngasak per lahan yang kemudian dikonversi dalam luasan hektar. Hasil penelitian menunjukkan jumlah kehilangan gabah rata-rata per hektar 343 kg/Ha, dan potensi kehilangan gabah bisa mencapai 523 kg/Ha.

Abstract

The Bengawan Solo River has a large and important role in the lives of the people in its flow from Central Java to East Java. However, it turns out that community activities often have an impact on Bengawan Solo, especially regarding pollution and environmental damage. One of the worrying phenomena is the blooming of Water Hyacinth, which occurred due to a long dry season, causing high concentrations of organic waste in river waters at the end of 2023. Increased human activities, including household activities, have resulted in higher amounts of waste being produced from time to time. The large amount of waste entering the river certainly causes an increase in river nutrients, thereby fertilizing Water Hyacinth along Bengawan Solo, including in the Kuncen village area, Padangan sub-district. So that household waste does not cause problems for the environment and health, it is necessary to carry out further processing of the waste. One type of household waste, namely vegetable waste, can be a source of alternative raw materials to be used as eco-enzyme products. LPPM Bojonegoro University in collaboration with Jasa Tirta I carries out community assistance activities by providing education and campaigning for awareness of the importance of maintaining the environmental condition of the Bengawan Solo river. This education and campaign is also aimed at minimizing waste from households, especially organic waste, so that there is no accumulation of nutrients that cause water hyacinth blooms. By implementing this community service, it was found that housewives' insight into managing household waste, especially vegetable scraps, increased, so that the waste could be managed into eco enzymes which are beneficial for the environment.

Abstract

Limbah adalah zat buangan yang dihasilkan dari aktivitas makhluk hidup, seperti proses produksi baik industri maupun domestik. Berdasarkan wujud atau bentuk fisiknya, limbah dibedakan menjadi 2 yaitu limbah padat dan limbah cair. Limbah cair domestik (klinik) adalah sisa hasil buangan atau semua air buangan termasuk tinja yang berasal dari kegiatan rumah sakit/klinik. Limbah cair domestik (klinik) perlu melewati beberapa tahap pengolahan agar sesuai dengan baku mutu dan tidak merusak lingkungan.  Penelitian ini bertujuan untuk mengevaluasi efektivitas pengolahan limbah cair domestik (klinik) di PPSDM Migas Cepu dalam memenuhi standar baku mutu yang ditetapkan oleh Peraturan Menteri Lingkungan Hidup Nomor 68 Tahun 2016. Metode penelitian ini merupakan jenis penelitian eksperimental di Laboratorium, dilakukan dengan pengumpulan data, pengambilan contoh di Unit Klinik PPSDM Migas Cepu dan analisis di Laboratorium Lindungan Lingkungan PPSDM Migas Cepu. Hasil penelitian menunjukkan bahwa 5 dari 6 parameter limbah cair domestik (klinik) yang diuji telah memenuhi baku mutu, yaitu pH, COD, amonia, minyak dan lemak, dan TSS, sedangkan parameter yang belum memenuhi baku mutu adalah BOD5. Hal ini menunjukkan bahwa pengolahan limbah cair domestik (klinik) di PPSDM Migas Cepu cukup efektif dalam menekan pencemaran, namun perlu dilakukan perbaikan untuk mencapai kepatuhan terhadap standar baku mutu BOD5 dalam meningkatkan kualitas air limbah dan dapat melindungi lingkungan.

Abstract

Wonocolo Geosite is a geoheritage known for the existence of the Kawengan Anticlinal Trap, which is the only one in the world, causing oil to be found in shallow locations. This condition has allowed for traditional mining since the Dutch colonial era and continues today. Geological history states that the anticlinal structure was formed when the Indo-Australian plate collided with the Eurasian plate, resulting in folds and uplift of the seafloor above the surface. However, there has not been much research supporting the truth of the theory. Therefore, evidence is needed to support the uniqueness of the Wonocolo Geosite. The fossil collection method was carried out simultaneously with the collection of substrates at the upstream, middle, and downstream riverbeds using 20 cm diameter PVC pipes at a depth of 10 cm.This study found marine macrozoobenthos fossils during substrate sampling in the upstream, middle, and downstream river beds using a PVC pipe with a diameter of 20 cm at a depth of 10 cm.  The samples were then identified in the laboratory, revealing fossils from the deep sea. The fossils found include Azooxanthellate (Cnidaria), which lives at depths of up to 2000 m; Dentaliida (Mollusca) which lives at depths of 500-7000 m and Foraminifera which also live in the deep sea. This phenomenon is unusual, considering that the fossils were found in a river far from the sea at an altitude of 250 MASL. Therefore, the discovery of marine macrozoobenthos fossils at the bottom of the Wonocolo River strengthens the theory of the formation of the Wonocolo Formation from a raised seabed which is also an important asset supporting the Wonocolo Geoheritage.
