Abstract

The North Coast of Jakarta is a strategic area to support the economy of the DKI Jakarta Province and as a place to live for organisms, one of which is phytoplankton. Phytoplankton is a primary producer in aquatic ecosystems that have an essential role in maintaining aquatic ecosystems and as an indicator of water quality. This study aims to determine the quality of seawater (turbidity, TSS, BOD, Phosphate, and Nitrate) and the diversity of species (H') of phytoplankton in the waters of the North Coast of Jakarta around the reclamation islands C and D from 2006 to 2021. Types of data used in this study is secondary data from Environmental Impact Analysis (ANDAL) documents and reports on the implementation of the Environmental Management Plan and Environmental Monitoring Plan for Reclamation and Development on Islands C and D. Concentrations of turbidity, TSS, BOD, phosphate, and nitrate in coastal waters North of Jakarta around the reclamation islands C and D are fluctuation and several sampling times exceed the quality standard. The species diversity index (H') of phytoplankton in the coastal waters of North Jakarta around the reclamation islands C and D is dominantly included in the criteria for community stability in stable conditions (H 3). Based on the partial correlation test, phosphate with the diversity of phytoplankton species in the waters of the North Coast of Jakarta around reclamation island C and D had a significant relationship (P 0.05).

Abstract

In the last decade we have realized that the plastics we use every day, and for practically everything, may be the biggest environmental polluters humans have ever released to the environment (EU DG, 2011). Since the first reports of plastic pollutions, we have learned so much about the issue. Macro and micro plastic pollution topics have been extensively studied, investigated, regulated, and in some cases litigated (Uren Webster et al., 2020)(Barnes, Galgani, Thompson, Barlaz, 2009)(Environment Agency, 2018). As it happened in most of the past cases, we have started with the most obvious and visible problem: macro plastics.

Abstract

Sustainable development focusing on environmental issues is the target of both central and local governments. Ideally, planning and funding this issue requires harmonizing and implementing top-down and bottom-up alignment. Neglect from a regional point of view often causes various obstacles in implementation, which of course, causes inefficiency. The allocation and distribution of budgeting through special transfer funds for environmental issues are interesting to elaborate with attention to the sustainability of the policy and the expected benefits. The analysis of the implementation of government funding support for the development of national priorities related to the environmental sector in the region is interesting to be elaborated more deeply to provide information on strategic control and integration of future development. This further elaboration is in line with the national economic recovery after the COVID-19 pandemic, which has attracted the attention of many parties. The method used in the analysis is a qualitative approach through literature review and limited discussion (FGD) with stakeholders at the central-regional level and through online survey methods. The literature review uses previous research, journals, books, and planning documents at the central and regional levels to capture the Physical SAF 2021 policy for the environment, analyze budget distribution, and analyze central-regional planning/funding alignment in terms of planning documents. Focus Group Discussion (FGD) method and online questionnaires are used to capture field problems. Expectations desired in this evaluation-based analysis can provide recommendations following the actual conditions in the area as the implementer of this fund.Pembangunan berkelanjutan yang berfokus pada isu lingkungan menjadi target pemerintah baik pusat maupun daerah. Idealnya, perencanaan dan pendanaan masalah ini membutuhkan harmonisasi dan implementasi top-down dan bottom-up. Pengabaian dari sudut pandang daerah seringkali menimbulkan berbagai kendala dalam pelaksanaannya, yang tentunya menimbulkan inefisiensi. Alokasi dan distribusi penganggaran melalui dana transfer khusus untuk masalah lingkungan hidup menarik untuk dijabarkan dengan memperhatikan kesinambungan kebijakan dan manfaat yang diharapkan. Analisis pelaksanaan dukungan pendanaan pemerintah untuk pembangunan prioritas nasional terkait bidang lingkungan hidup di daerah menarik untuk dielaborasi lebih dalam guna memberikan informasi pengendalian strategis dan keterpaduan pembangunan ke depan. Penjelasan lebih lanjut ini sejalan dengan pemulihan ekonomi nasional pasca pandemi COVID-19 yang menjadi perhatian banyak pihak. Metode yang digunakan dalam analisis adalah pendekatan kualitatif melalui kajian pustaka dan diskusi terbatas (FGD) dengan pemangku kepentingan di tingkat pusat dan daerah serta melalui metode survei online. Tinjauan literatur menggunakan penelitian sebelumnya, jurnal, buku, dan dokumen perencanaan di tingkat pusat dan daerah untuk menangkap kebijakan SAF Fisik 2021 untuk lingkungan, menganalisis distribusi anggaran, dan menganalisis keselarasan perencanaan/pembiayaan pusat-daerah dalam hal dokumen perencanaan. Metode Focus Group Discussion (FGD) dan kuesioner online digunakan untuk menjaring permasalahan lapangan. Harapan yang diinginkan dalam analisis berbasis evaluasi ini dapat memberikan rekomendasi sesuai dengan kondisi aktual di daerah selaku pelaksana dana ini.

Abstract

Food is a basic human need. The state must strive to meet the availability of food for people in a sustainable manner. One of the efforts is to maintain and develop paddy fields as a food source as a supplier of 95% of national rice production. The conversion of paddy fields is a reason of decreasing of food production in Purwakarta Regency, which impact on food availability and security. This research was aimed to provide a portrait of the rate of conversion of paddy fields in Purwakarta. This research is a quantitative descriptive research using spatial analysis to compare two period of times: 2013-2017 period and the 2017-2021 period. The results of spatial analysis in the 2013-2017 period showed that Purwakarta Regency experienced a reduction in paddy fields by 195.55 ha (1%) consisting of paddy fields turned into industry 117.99 ha; roads 5.72 ha; settlements of 42.30 ha and housing, trade and services of 29.55 ha. Meanwhile, in the 2013-2017 period, paddy fields turned into industry 151.72 ha, roads by 23.54 ha, settlements 196.76 ha, and housing, trade and services 29.81 ha. The results of this study reinforce that the reduction in food production in Purwakarta was caused by the conversion of paddy fields into other uses during the 2013-2017 and 2017-2021 periods.

Abstract

Paper and garden waste are among the various types of rubbish commonly encountered in urban areas in Indonesia, including the city of Depok. Notably, not all paper waste can be recycled by garbage collectors into new products. In addition, garden waste is also garbage, one of the wastes produced daily from gardening activities. This study analyzed the potential for reducing paper and garden waste using as Refuse-Derived Fuel or RDF in Depok City. This study analyzes the quality of RDF based on the parameters of water content, ash content, density, and calorific value resulting from the material substitution. The results were analyzed using the multicollinearity and Kepner-Tregoe Decision Analysis (KTDA). The results of the multicollinearity test showed that the ash and water content could reduce the calorific value of RDF mixed with paper and garden waste. The addition of garden waste composition can increase the calorific value. Based on the results of decision analysis using KTDA, it shows that the variation of the mixture of 75% paper waste and 25% wood waste has the most prominent points compared to other variations. Material Flow Analysis (MFA) utilization of this waste can reduce the generation of paper and garden waste by 3.5% and 12.3%, respectively.Sampah kertas dan kebun adalah beberapa jenis sampah yang biasa ditemukan di perkotaan di Indonesia, termasuk kota Depok. Perlu dicatat, tidak semua sampah kertas dapat didaur ulang oleh pemulung menjadi produk baru. Selain itu, sampah kebun juga merupakan salah satu sampah yang dihasilkan sehari-hari dari kegiatan berkebun. Kajian ini menganalisis potensi pengurangan sampah kertas dan kebun dengan menggunakan Refuse-Derived Fuel atau RDF di Kota Depok. Penelitian ini menganalisis kualitas RDF berdasarkan parameter kadar air, kadar abu, berat jenis, dan nilai kalor hasil substitusi bahan. Hasil penelitian dianalisis menggunakan multikolinearitas dan Analisis Keputusan Kepner-Tregoe (KTDA). Hasil uji multikolinearitas menunjukkan bahwa kadar abu dan air dapat menurunkan nilai kalor RDF yang bercampur dengan kertas dan sampah kebun. Penambahan komposisi sampah kebun dapat meningkatkan nilai kalor. Berdasarkan hasil analisis keputusan menggunakan KTDA menunjukkan bahwa variasi campuran 75% limbah kertas dan 25% limbah kayu memiliki poin paling menonjol dibandingkan variasi lainnya. Pemanfaatan Material Flow Analysis (MFA) limbah ini dapat mengurangi timbulan limbah kertas dan kebun masing-masing sebesar 3,5% dan 12,3%.

Abstract

Traditional methods of species identification involve collection and killing of specimens. The associated costs and expertise required are prohibitory. In this paper we describe the first documented record of Heterosphecia tawonoides in its natural habitat in Sumatra since 1887, reporting its identification using photographs uploaded to citizen science platform iNaturalist. Our findings add valuable information to the small body of work on this species and  demonstrate the importance of having freely available high quality tools such as iNaturalist without which this important record would not have been reported and the observation of this rarely seen moth species in Sumatra would have remained  unknown.

Abstract

This study aims to determine the differences in daily behaviour and home range of male and female rehabilitated Javan slow loris (Nycticebus javanicus) in Gunung Sawal Nature Reserve, Ciamis, West Java, Indonesia. The study was conducted on four individuals of Javan slow loris rehabilitates (two adult males and two adult females) during their post-released monitoring period. Those animals were fitted with a radio transmitter and were monitored for their daily behaviour and home range for six months (May - October 2018). The focal animal sampling method was employed for daily behaviour observation. The home range of each individual was estimated by Minimum Convex Polygon (MCP) and Kernel Density Estimation (KDE) methods. Data analysis was descriptively displayed in maps, tables, and figures. According to the statistical analyses of the Mann Whitney U test, there are no significant differences (μ = 1,074,554.5 [p 0.01]; P-Value 0.238 0.01) in the daily behaviour of male and female Javan slow loris rehabilitate. In contrast, the home range (vertically and horizontally) of female and male Javan slow loris rehabilitate are significantly different (μ = 816,286.0 [p 0.01]; P-Value 0.000 0.01).   Penelitian ini bertujuan untuk mengetahui perbedaan perilaku harian dan wilayah jelajah kukang jawa (Nycticebus javanicus) jantan dan betina hasil rehabilitasi di Suaka Margasatwa Gunung Sawal, Ciamis, Jawa Barat, Indonesia. Penelitian dilakukan pada empat individu kukang jawa rehabilitan (dua jantan dewasa dan dua betina dewasa) selama masa pemantauan pasca pelepasliaran. Satwa-satwa tersebut dipasangi pemancar radio serta dipantau perilaku harian dan wilayah jelajahnya selama enam bulan (Mei - Oktober 2018). Metode pengambilan sampel "Focal Animal" digunakan untuk pengamatan perilaku harian. Daerah jelajah masing-masing individu diperkirakan dengan metode Minimum Convex Polygon (MCP) dan Kernel Density Estimation (KDE). Analisis data secara deskriptif ditampilkan dalam bentuk peta, tabel, dan gambar. Berdasarkan analisis statistik uji U-Mann Whitney, tidak terdapat perbedaan yang bermakna (μ = 1.074.554,5 [p 0,01]; P-Value 0,238 0,01) pada perilaku harian kukang jawa jantan dan betina yang direhabilitasi. Sebaliknya, wilayah jelajah (vertikal dan horizontal) kukang jawa betina dan jantan yang direhabilitasi berbeda nyata (μ = 816.286,0 [p 0,01]; P-Value 0,000 0,01).

Abstract

The Global Assessment Report on Biodiversity and Ecosystem Services 2019, published by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), shed light on the increasingly alarming state of global biodiversity. Biodiversity is essential to human survival through its contribution to ecosystem stability, resilience, and the provision of critical ecosystem services that sustain essential ecological processes and human well-being. Amongst other services, as demonstrated across Indonesia, biodiversity supports livelihoods by providing building and clothing materials, maintaining water quality, and providing medicines and food. As the global human population reached 8 billion in 2022, the interconnections between  our unsustainable production and consumption, the climate crisis, and biodiversity decline have been increasingly recognized by the global community through IPBES and IPCC (Intergovernmental Panel on Climate Change). Escalating human numbers, coupled with burgeoning economic and industrial demands, must necessitate substantial forest land use—repositories of biodiversity. Conservation practitioners have therefore been continually driven to innovate in their pursuit of effective strategies for sustainably managing the world's precious biodiversity. Researchers and academics have the pivotal responsibility to produce research that brings about real-world impactful outcomes. The academic community is expected to address the needs of those working to conserve nature through the development of research and technology with immediate practical applicability. We look forward to publishing more of these research impact papers in the future.
