Abstract

Indonesia plans a target of reducing carbon emissions in the Nationally Determined Contribution (NDC) of 29 percent in 2030 on a business as usual basis (BAU) and 41 percent with international assistance until 2050. NDC is a measurable commitment in dealing with the threat of climate change, the main cause of which is the increasing emission of greenhouse gases. glass/GHG to the atmosphere. The composition of GHG itself is 94 percent in the form of carbon dioxide, CO2 produced by human activities. Almost all human activities contribute 75 percent to carbon emissions because their activities tend to come from the use of fossil fuels, BBF. Taking into account the source of carbon emissions is the largest of the main human activities, then to detect the amount of carbon emissions into the atmosphere is to calculate the individual carbon footprint, carbon footprint. The results of individual carbon footprint studies in several places/regions and nationally are informed as follows: in the Puspiptek Serpong Tangerang area, an individual carbon footprint of around 3.1-6.6 tons CO2e per year was obtained, in Semarang, Central Java an individual carbon footprint value of around 3.84 tCO2e per year was obtained. , Medan, North Sumatra produces what individual carbon footprint values ??are around 2.52 tCO2e per year, at the national level the calculation of individual carbon footprints is approached by dividing the total carbon emission data published by the Ministry of Environment and Forestry in the period 2010-2018 with the total population of Indonesia at that time, we get a range of figures carbon footprint from 3.40 sd. 9.29 tCO2e per year. The highest number occurred in 2015.

Abstract

Penambahan ruang di lahan-lahan terbuka hingga ke daerah pinggiran kota mengakibatkan bertambah luasnya lahan (dengan fungsi perkotaan) terbangun (urban built-up land). Dengan semakin tingginya tingkat pembangunan di kawasan tersebut yang tanpa terkendali (unplan) dikemudian hari akan menimbulkan dampak negatif yang dirasakan yang ditandai dengan penuruan kualitas lingkungan itu sendiri. Sebagaimana diketahui bahwa wilayah Dayeuhkolot (termasuk hulu sungai Citarum) merupakan daerah rawan banjir dan genangan dimana beberapa desanya termasuk daerah yang sering dilanda banjir. Berdasarkan telaahan maka terdapat akar pemasalahan yang menyebabkan wilayah hulu sungai Citarum setiap tahun mengalami banjir dan genangan yaitu perkembangan penggunaan lahan terbangun (built up area) selama kurun waktu 1993-2013 tahun telah mencapai 78,95% dari luas wilayah Kecamatan Dayeuhkolot 1.078,60 ha dibanding lahan non terbangun yang menyisakan luas sebesar 21,05% dari 1.078,60 ha, angka daya dukung lahan wilayah Kecamatan Dayeuh Kolot menunjukan 0,0098 sudah berada diluar ambang batas konsumsi lahan populasi antara 100.000-250.000 jiwa dan hasil analisis dari Rencana Pola Pemanfaatan Ruang Wilayah Kecamatan Dayeuh Kolot untuk kawasan budidaya non pertanian (kawasan terbangun) mencapai 85% dan sisanya 15% untuk kawasan budidaya pertanian.

Abstract

Landslide forensic can be investigated using dendrogeomorophological method. This method can be used to predict future landslide on the basis of the analysis of the past landslide. However, this method has not been used in Indonesia although the prospects of research using this method is possible. Plants will respond to a landslide event where plants in landslide area can be injured, tilted, scratched, the roots are damaged or partially removed. This plant can then continue to grow and track a record of the landslide event indicated by the abrupt changes in tree rings series. The combined study between the landslide geomorphology and plant response through the pattern changes in tree rings series can reveal landslide events so that the forensics of landslide can be described. Furthhermore the landslide events can be predicted both in time space, allowing for a more precise landslide disaster mitigation, spatial planning and management.

Abstract

Heavy metals are common environmental contaminants. Depending on the amount and chemical species that present, these heavy metals can turn into environmental pollutants which in certain environmental conditions can be in a biologically available form so that they have the potential to cause toxic effects. Analysis of the risk of heavy metal exposure by relying on the total amount of heavy metals does not provide a real picture of the relationship between exposure and toxicity. A chemical speciation approach that takes into account the chemical state of heavy metal species with potential for mobility, bioavailability and toxicity is a more rigorous strategy in risk analysis of heavy metal exposure. This is because the large total amount of heavy metals is not necessarily able to provide the metal in a biologically available form. On the other hand, the total amount of heavy metals which is considered safe because it does not exceed the regulatory quality standards, but chronic exposure to the forms of chemical species that are biologically available actually poses a threat in the long term. With the support of reliable laboratory equipments and accurate computational chemical speciation modeling, the heavy metal chemical speciation approach is the right tool in environmental pollution risk analysis.

Abstract

Abstract Natural resource management must be oriented towards the conservation of natural resources (natural resource orientation). To balance the management of natural resources and human interests, the Government of Indonesia issued Law no. 32 of 2009 on Environmental Protection and Management of natural resources in Indonesia. Even though this law already exists, in fact there are still frequent inequalities and violations in the exploitation of Indonesia's natural resources, according to JATAM data at the end of 2020 in cases of pollution and environmental destruction in coal mining. One of them occurs in the coal mining industry. Coal mining located in the village of Pembeliangan, Sebuku District, Nunukan Regency, North Kalimantan Province, plans to increase coal production to 3 million tons/year (PT CMC, 2022). If not managed properly, the development of coal production will have a potential impact on the environmental degradation of upstream rivers. Therefore, in order to overcome environmental degradation, a study will be carried out to determine the water quality status of the coal mine site by analyzing the river water quality in accordance with the river water quality standards with reference to Government Regulation No. 22 of 2021. The next stage will be determining the river water pollution index and appropriate mitigation efforts to prevent river water pollution. Keywords: surface water quality, mitigation, water pollution index Abstrak Dampak pertambangan batubara terhadap lingkungan dapat menyebabkan degradasi lingkungan, seperti menurunnya kualitas air permukaan. Efek lingkungan penambangan batubara bertahan selama bertahun-tahun setelah operasi penambangan selesai. Oleh karena itu pertambangan batubara yang merupakan salah satu sumber daya alam Indonesia harus dikelola. Untuk keseimbangan pengelolaan sumber daya alam dan kepentingan manusia, Pemerintah Indonesia mengeluarkan UU No. 32 Tahun 2009 tentang Perlindungan dan Pengelolaan Lingkungan Hidup. Walaupun sudah ada undang-undang ini, dalam realitasnya masih sering terjadi ketimpangan dan pelanggaraan di dalam eksploitasi kekayaan alam Indonesia, data JATAM akhir tahun 2020 tentang kasus pencemaran dan perusakan lingkungan di pertambangan batubara. Salah satu pertambangan batubara dengan produksi cukup besar di Kalimantan Utara terdapat di desa Pembeliangan, Kecamatan Sebuku Kabupaten Nunukan. Pertambangan ini merencanakan penambahan produksi batubara menjadi 3 juta ton/tahun (PT CMC,2022). Penambahan produksi batubara juga akan mempunyai potensi dampak berupa degradasi lingkungan di hulu sungai, seperti pencemaran terhadai air sungai. Oleh karena itu untuk mengatasi terjadinya penurunan kualitas air sungai maka akan dilakukan studi untuk mengetahui status kualitas air di lokasi pertambangan batubara dengan melakukan analisis kualitas air sungai, kemudian membandingkan hasilnya dengan baku mutu air sungai pada Peraturan Pemerintah No.22 Tahun 2021. Tahap selanjutnya akan dilakukan penentuan indeks pencemaran air sungai dan upaya mitigasi yang tepat untuk mencegah pencemaran air sungai tersebut.

Abstract

Jakarta's coastal areas are prone to flooding problems. Floods are generally caused by high-intensity rain, river runoff and tidal waves from sea water. The main causes of this situation are land subsidence, increased river discharge from upstream areas and local rainfall which is not accommodated by the existing drainage system. With the plan to build a giant sea wall in the bay of Jakarta, it is estimated that the sea water rob that hit DKI Jakarta can be overcome. The construction of the giant sea wall and PTPIN requires massive materials for concrete and civil constructions. Fly ash and bottom ash wastes from coal fired power plant have physical characteristics that are estimated to meet PTPIN's needs. In addition, the characteristics of TCLP, LD50 and radioactive of FABA wastes also meet the PP22/2021 criteria. By utilizing the FABA wastes, the exploitation of natural materials for the construction of PTPIN can be avoided so that the PTPIN development process takes place in an environmentally friendly and sustainable manner. Utilization of FABA wastes is in line with circular economy efforts and can change the mindset of FABA wastes from a cost center to a revenue center.

Abstract

Plant roots have the function of reducing groundwater that is saturated by rainwater, strengthening soil aggregation so that it supports plant growth and prevents erosion, increases infiltration, and holding capacity. Vertical soil stabilization is also carried out by the plant root system and also the effect of drainage that occurs through the process of water absorption and transpiration. This indicates that root system of plants has an important contribution to slope reinforcement and erosion mitigation. Vetiver grass (Chrysopogon zizanioides) is an perennial grasses that has been shown to slope reinforcement and erosion mitigation, because vertiver grass has physical, mechanical and hydraulic characteristics that support the stabilization mechanism. The unique root system is the fibrous root with fine and massive structure, fast growing and deep, has an average tensile strength of 75 MPa provides a stability effect. Dense hedgerows of vetiver grass with rigid stems formed from rows of plants can fuction as structure of a highly effective water transfer for spreading and diverting to stable areas so that the possibility of erosion is controlled. This paper presents the results of a study on the ability of vetiver grass to strengthen slopes and erosion mitigation by exploring the physical, mechanical and hydraulic characteristics of the plant. Keywords : vetiver grass, physical, mechanical and hydraulic characteristics, slopes reinforcement, erosion mitigation.

Abstract

The region of Indonesia is occupied by many volcanoes, both active and inactive. Volcanic products usually form a steep morphology and are often composed of volcanic deposits that are not yet compact or relatively loose. Such natural phenomena are very prone to landslides, and some of them forms natural dams that potential to be a source of flash floods. To find out the cause of the landslide, involving a big volume of landslide material and the formation of a natural dam, a study was conducted on the Way Ela Natural Dam. The research, in addition to using secondary data, also carried out field observations. The results showed that the landslide at Bukit Uluh Hatu involved a very large volume, due to the rock structure that was strongly fractured, the slope was very steep, the influence of the earthquake that enlarged opened layers and the high rainfall reached 360 mm. Meanwhile, the formation of natural dams is not only due to the large volume of landslides, but also due to the narrowing of the valleys which causes bottle necking of the flow of water and landslide material.

Abstract

Cilacap is located on the southern coast of Central Java, facing the confluence of the Indo-Australian Plate and the Eurasian Plate as well as the Megathrust south of Java, so it has a high chance of an earthquake and tsunami disaster. With the issuance of Presidential Regulation (Perpres) No. 93 of 2019 concerning Strengthening and Development of Earthquake Information Systems and Tsunami Early Warning, mandates the implementation of deep sea level tsunamis (buoys) and Cable-Based Tsunameters (CBT). The development of a tsunami early detection system using InaCBT submarine cable technology is the development of the Advanced Cable Based Tsunameter (AdvCBT). For the implementation of the AdvCBT development activities, a submarine cable route is planned from Krui, Pelabuhan Ratu and Cilacap. The location of the landing station (LS) in the form of a power house (PH), communication tower and beach manhole (BMH) must be determined prior to the construction of the AdvCBT infrastructure. Cilacap is one of the places that will be the location of the landing station of the AdvCBT. Scoring is carried out to obtain the best alternative location by considering: land availability, safe elevation against tsunamis, cable routes that do not cut rivers or roads, GSM signal conditions, electricity availability, soil stability, distance from the beach, social conditions of the community, environmental conditions, and safe from other obstacles. Analysis of eleven alternative landing station locations based on the scoring, the results show that the highest score for the alternative location is ALT-09, and ALT-08, both locations are located in Karangbenda, Kec. Adipala, Cilacap Regency, Central Java. Of the eleven (11) alternative landing station locations as a result of the desktop study, it was found that the highest scores for the alternative landing station locations were ALT-09 and ALT-08, both of which were located in Karangbenda, Kec. Adipala, Cilacap Regency, Central Java.
