Abstract

The use of land is a part of the fulfillment of human needs. The establishment of a large-scale infrastructure project often triggers an increase in land cover around its infrastructure project. Most of the increase in built up land tends to occur in areas that are traversed by or located near main accessibility routes such as toll roads. Although the construction of toll roads can improve accessibility between regions, land is a limited resource. So that it becomes the basis for researchers to identify the changes in land use in regencies and cities on the island of Sumatra that are crossed by toll roads that have been operating. The goal of land use change analysis is to give a description or explanation, predict, look at the effects, and make a decision (prescription). This research was conducted by identifying the changes in the existing land cover and predicting the land cover using cellular automata. Cellular automata have proven to be a method that is suitable for predicting the dynamics of land use through spatial simulation. The results show that there was an increase in the amount of land built from early 2017 to 2030. The covered land is developed around the toll gate after it is actively operated. In all provinces studied, deviation discrepancies were found in the conservation and cultivation areas. Deviations that occur in conservation areas need to be considered as there should be no land built in these areas, which means that there are cultivation activities in the conservation areas.

Abstract

Crude oil contamination is considered highly toxic and poses a significant environmental problem. As an alternative, the laccase enzyme showed high performance for removing various toxic contaminants, particularly oil-contaminated soil (i.e., total petroleum hydrocarbon). However, previous studies mainly tested the performance of laccase under irrelevant environmental conditions (i.e., artificially contaminated soil) with a limited number of soil samples, which can lead to bias optimization results for assessing laccase performance. Two types of natural oil-contaminated soils were tested under various reaction times and various concentrations of laccase extracted from Marasmiellus palmovorus. In addition, response surface methodology was used to find the maximum degradation of total petroleum hydrocarbon (TPH). The maximum degradation of TPH from soil A and soil B were 48.57% and 54.1%, respectively. Moreover, the performance of the laccase enzyme for oil recovery was also tested, with the percentage of oil recovery being 9.89% and 10.1 % for soil A and soil B, respectively. SARA fraction analysis indicated that laccase enzyme preferentially degraded highly polar SARA fraction (i.e., asphaltene and resin). In general, the application of laccase for the enzymatic remediation of oil-contaminated soils was practical. Hence, the use of laccase for environmental application is still promising.

Abstract

Urban water management efforts are essential in encouraging the fulfillment of the SDGs targets. One action that can be done is to approach the calculation of the actual water consumption value. This research conducted a survey of domestic water consumption in Bandar Lampung City to obtain comprehensive information. Bandar Lampung City was chosen because it is one of the cities on the island of Sumatra with a high economic growth rate. Lampung Province is the top 3 province in Sumatera Island with the higher Gross Domestic Product Growth on 2022, with Bandar Lampung as its capital city. Furthermore, water consumption patterns were analyzed for various activities, socio demographic conditions, and the community's economy. The results showed that of the 404 samples, the average water usage was 195.08 liters/person/day, with the dominant activities in use including bathing (66.84 liters/person/day), flushing the toilet (35.71 liters/person) / day), and ablution (29.74 liters/person/day). Furthermore, the variable number of family members in one house and income level have significant different on total domestic water consumption. The results obtained in this study are expected to assist in making decisions regarding urban water management plans.

Abstract

The presence of algae caused by anthropogenic eutrophication in water has become a severe environmental issue. Various treatment options for algae removal have been developed, such as filtration, coagulation, sedimentation, flotation, algicides, ozone, and photolysis. However, these technologies are complex, expensive, consume considerable amounts of various chemicals, and may cause further pollution (i.e., by-product formation). Ultrasonic exposure is an alternative method for removing algae from water that is environmentally friendly (i.e., no addition of chemicals) and almost unaffected by any turbidity in the water. In this study, process optimization of ultrasonication (e.g., by adjusting frequency, power intensity, and exposure time) for the removal of alga was tested under vacuum and non-vacuum conditions. Experiments were conducted on a batch of algae solution in a clear glass tube ultrasonicated by a 20 kHz transducer for 180 minutes. The tube was depressurized up to -67 N/m2 in a depressurizing chamber. The data was collected at transducer depths of 0.06, 0.13, and 0.19 m. It was concluded that the optimum condition (i.e., 92% algal cell disruption) was achieved when the power intensity was 7 kWh/m3, under vacuum conditions, at a frequency of 20 kHz and 180 minutes of exposure time. Higher power intensity gave higher energy for cell disruption, moreover by depressurizing the air above the algae solution, the lysis effect for algae reduction increased from 20% to 70% compared to the non-depressurized system due to higher cavitation bubble production. In addition, the depth of the transducer was another factor that could increase the lysis of the algae water. Therefore, this technology has future potential application for algae removal from water.

Abstract

global warming and environmental issues are being caused by the overuse of fossil fuels and increased industrialization around the world, which has resulted in the production of greenhouse gases. As a result, it's crucial to reach net-zero carbon emissions. By balancing the total quantity of carbon dioxide or other greenhouse gas emissions over a specific period and taking actions that are ecologically responsible, net zero carbon emissions can be accomplished. For environmental sustainability to be successful, it must be able to influence people's attitudes and behavior toward the environment. To understand NGOs' obligations in supporting net-zero carbon emissions, this paper presents a methodical debate utilizing NGOs as case studies. The method is employed in this work by reviewing the body of primary and secondary research on the study issue. This essay initially lists different environmental NGOs organizations before categorizing and outlining some of the significant GHGs reduction initiatives made by these organizations. This essay also addresses key issues that must be addressed upon to achieve the best outcomes. This report gives a broad overview of the synergizing domains that NGOs around the globe work in to assist improvement environmental security.

Abstract

Data SIPSN tiga tahun terakhir menunjukkan timbulan sampah di Kabupaten Langkat meningkat 24,71% atau dari yang awalnya 152.099 menjadi 189.685 ton. Lebih dari 42% timbulan sampah disumbangkan oleh sektor domestik yang seharusnya dapat dikelola sedekat mungkin dari sumbernya. Dengan demikian, kegiatan pengabdian kepada masyarakat ini bertujuan memberikan pelatihan agar masyarakat lebih memahami cara mengurangi timbulan sampah dengan mengubahnya menjadi produk yang bermanfaat. Pelatihan dilaksanakan pada 5 Agustus 2021 di Rumah Komunitas Pohon Rindang, Desa Perkebunan Bukit Lawang, kepada 43 anak usia 8-15 tahun. Metode yang digunakan adalah penyuluhan interaktif dengan memberikan demonstrasi cara membuat keranjang takakura dan stringbag. Keranjang takakura 45x37x57 cm dapat menampung hingga 1,5 kg sampah organik basah per hari, sedangkan pembuatan pakaian bekas menjadi stringbag dapat menunda pembuangan material ke TPA. Dalam jangka panjang kegiatan ini diharapkan menjadi kebiasaan baru bagi masyarakat dalam mengelola sampah untuk menjadikan Desa Perkebunan Bukit Lawang sebagai desa pariwisata yang berkelanjutan.

Abstract

Gunungtiga area has never been studied for the quality of groundwater, and residents have also complained about the quality of groundwater, these became the basis for selecting the research location. This study aims to analyze groundwater quality in the Gunungtiga Region, Lampung Province. Quantitative approached was used for this research, it was carried out by mapping the groundwater level to estimate the recharge area and collecting data on parameters of the physical properties of groundwater, including color, taste, odor, temperature, pH, TDS, and EC.  The physical properties approach was selected because it is relatively cheap and easy to observe, the data collection can also be done in situ. The physical property parameter data is then checked based on the Republic of Indonesia Minister of Health Regulation No. 492 of 2010. The observations at 14 points showed that the groundwater level in the research area is relatively shallow towards the west or in the direction with higher topography, so it can be interpreted as a recharge area, and it flowed towards the east area which has lower topography. The physical properties of the groundwater had no taste, odor, or color. The EC value ranges from 188.07 to 1066.82 µs/cm, including fresh water, the pH ranges from 5.41 to 7.5, the temperature ranges from 27.2 to 29.7 0C, and the TDS value ranges from 94. 04-542.91 mg/l. Of the 14 observation points, only 1 location met the quality standards, namely 22/DP/02. Treatment is required before groundwater can be used, such as filtering.

Abstract

Penelitian yang dilakukan di Pulau Pasaran, Bandar Lampung, membahas tantangan yang terkait dengan pengelolaan sampah di wilayah tersebut. Kompleksitas pengelolaan sampah ini timbul karena adanya ketergantungan pada berbagai sektor yang berbeda. Studi ini bertujuan untuk melakukan analisis yang terintegrasi, dengan fokus pada aspek timbulan sampah, komposisi sampah, dan pemangku kepentingan yang terlibat. Metode AHP digunakan untuk menilai 21 sub-kriteria yang telah diidentifikasi dalam lima kriteria pengelolaan sampah. Pengumpulan data dilakukan melalui pengambilan sampel yang mengikuti standar SNI-19-3694-1994, wawancara, penggunaan kuesioner, serta metode dokumentasi. Analisis pemangku kepentingan dilakukan terhadap sepuluh responden, dan hasilnya mengungkapkan bahwa aspek lingkungan memiliki tingkat kepentingan yang lebih tinggi dalam pengambilan keputusan terkait aspek pengelolaan, dengan bobot sebesar 0,326. Sub-kriteria yang diidentifikasi sebagai prioritas yang perlu dipertimbangkan dalam proses pengambilan keputusan ini meliputi kemudahan pemeliharaan, partisipasi masyarakat, polusi tanah dan air, kerjasama antar pemangku kepentingan, serta peningkatan manfaat bagi masyarakat. Dari berbagai alternatif yang dipertimbangkan, model pengelolaan skala rumah tangga yang melibatkan pemilahan dan pengomposan, serta didukung oleh konsep bank sampah dan pemanfaatan oleh RINDU, muncul sebagai pilihan yang paling sesuai.
