Flooding is a serious problem in Jakarta, and detailed estimation of flood damage is necessary to design optimal flood management strategies. This study aims to estimate flood damage in a densely populated area in Jakarta by means of a survey, to develop the relationship between flood characteristics and flood damage, and to compare the damage estimates from the survey with the damage estimates obtained by a flood damage model for Jakarta, i.e. the damage scanner model. We collected data on economic losses of the January 2013 flood in a survey of flood-affected households and business units in Pesanggrahan River. The actual flood damage in the survey area is US$ 0.5 million for the residential sector and US$ 0.7 million for the business sector. The flood damage for a similar event in the same area based on the damage scanner model is estimated to be US$ 1.3 million for the residential sector and US$ 9.2 million for the business sector. The flood damage estimates obtained by the survey approach are lower compared to the damage scanner approach due to different ways in obtaining flood damage data and in defining the maximum flood damage per object, the different spatial levels of analysis, and uncertainties in constructing the flood damage curves that were applied in the damage scanner model.
Peningkatan transaksi di marketplaces menyebabkan lonjakan jumlah pengiriman paket belanja online dan berimplikasi pada timbulan sampah yang didominasi oleh material plastik. Penerapan eco-friendly packaging di marketplaces sangat diperlukan dalam upaya mengurangi timbulan sampah dan dampak negatifnya terhadap lingkungan. Upaya ini pun akan mendukung pencapaian Sustainable Development Goals (SDGs) poin 12.5 yaitu mengurangi timbulan sampah secara substansial pada tahun 2030 melalui upaya pencegahan, pengurangan, daur ulang, dan penggunaan kembali. Penelitian bertujuan untuk 1) mengidentifikasi bentuk-bentuk eco-friendly packaging yang potensial diterapkan di marketplaces, 2) menganalisis preferensi konsumen terhadap penggunaan eco-friendly packaging, dan 3) merumuskan strategi penerapan eco-friendly packaging di marketplaces. Studi literatur, analisis deskriptif kualitatif, dan Contingent Choice Modelling (CCM) digunakan untuk menjawab tiga tujuan tersebut. Penelitian ini memformulasi sembilan alternatif eco-friendly packaging yang dapat diterapkan di marketplaces. Data diperoleh dari literatur dan survei secara blended terhadap 314 responden di Provinsi DKI Jakarta, Jawa Barat, dan Jawa Tengah. Studi literatur menunjukkan recyclable cardboard dan bioplastic dapat menjadi alternatif eco-friendly packaging yang paling relevan untuk marketplaces di Indonesia karena murah dan bahan terbaik. Analisis CCM mengungkap bahwa konsumen berminat terhadap eco-friendly packaging, mayoritas mengetahui manfaat penggunaannya dan bersedia untuk menggunakannya dengan total WTP maksimum sebesar Rp1.348,47 dan Rp4.237,80. Nilai Willingness to Pay (WTP) berpotensi meningkat jika konsumen diberikan edukasi manfaat eco-friendly packaging, dan berdomisili di DKI Jakarta. Lima strategi agar implementasi eco-friendly packaging di marketplaces dapat efektif, yaitu 1) menetapkan harga maksimum eco-friendly packaging sebesar Rp1.348,47, 2) memberikan edukasi manfaat eco-friendly packaging, 3) bila pilot project diperlukan, DKI Jakarta dapat menjadi provinsi percontohan, 4) memberikan voucher eco-friendly packaging, serta 5) mewujudkan kerja sama antara pemerintah, marketplaces, penjual, dan konsumen. Pemerintah dapat menetapkan regulasi yang meminta marketplaces untuk menyediakan opsi eco-friendly packaging pada fitur pemilihan kemasan serta pemberian edukasi dan promosi penggunaan eco-friendly packaging untuk menarik minat konsumen.ABSTRACTMarketplaces have increased the number of online-shopping package shipments and waste generation, which is dominated by plastic materials. Eco-friendly packaging is imperative to reduce waste generation including its negative environmental impacts. This effort is inline with Sustainable Development Goals (SDGs) point 12.5 i.e. by 2030, achieve the sustainable management and efficient use of natural resources. This study aims to 1) identify forms of eco-friendly packaging that to be applied in marketplaces, 2) analyze consumer preferences for eco-friendly packaging, and 3) formulate strategies for implementing eco-friendly packaging in marketplaces. Study literature, descriptive analysis and contingent choice modeling (CCM) were used to answer the objectives. CCM formulated nine alternatives of eco-friendly packagings which can be applied in marketplaces. Data were obtained from literature stud and blended surveys to 314 respondents living in DKI Jakarta, West Java and Central Java provinces. The results show that recyclable cardboard and bioplastic can be an alternative to eco-friendly packaging in marketplaces. CCM analysis reveals that consumers are interested in eco-friendly packaging, most of them are aware to its benefits and willing to use it with a maximum total WTP of IDR 1,348.47 and IDR 4,237.80. These WTPs could increase under two conditions i.e., if the benefits of eco-friendly packaging are described to consumers before they select the packaging and if the consumers are living in DKI Jakarta province. Five strategies for the implementation of eco-friendly packaging in marketplaces include 1) setting the maximum price for eco-friendly packaging at Rp1,348.47, 2) providing education on the benefits of eco-friendly packaging, 3) if a pilot project is needed, DKI Jakarta province can become a pilot province, 4) provide eco-friendly packaging vouchers, and 5) create cooperation between the government, marketplace, sellers, and consumers. The government could set a regulation which ask marketplaces to provide eco-friendly packaging options in the packaging selection features as well as educating and promoting the use of eco-friendly packaging to gain consumer’s interest.
Pertumbuhan ekonomi penting bagi masyarakat, tetapi jika kerusakan lingkungan seperti pencemaran udara dan emisi CO2 yang terus meningkat maka justru akan merugikan masyarakat. Dalam hal ini, konsep green economy muncul untuk mencapai pembangunan berkelanjutan salah satunya melalui sektor energi, dimana pengembangan PLTA menjadi salah satu upayanya. Tujuan dari penelitian ini adalah mengestimasi pengaruh jangka pendek dan panjang produksi listrik dari PLTA serta konsumsi batu bara, gas alam, dan minyak bumi terhadap emisi CO2 di Indonesia dan mengevaluasi hipotesis Environmental Kuznets Curve (EKC) dalam konteks energi baru terbarukan (EBT) Indonesia. Untuk menguji hal tersebut, penelitian ini menggunakan metode Autoregressive Distributed Lag (ARDL) dengan data sekunder dari tahun 2000-2018. Hasil penelitian menunjukkan bahwa konsumsi bahan bakar fosil akan meningkatkan emisi gas rumah kaca (GRK) jangka pendek maupun panjang sementara peningkatan produksi listrik dari PLTA akan menurunkan emisi gas rumah kaca. Hingga saat ini, Indonesia masih berada di posisi scale effect, artinya kerusakan lingkungan dengan indikator emisi CO2 terus meningkat akibat aktivitas perekonomian.
The Palu City Government plans to reactivate the biogas power plant (PLTBg) project in Kawatuna landfill, which was operated in 2013. Both economic and environmental benefits of the project are important for decision makers. The environmental benefit include the potential reduction of greenhouse gases (GHGs) emissions by the project. The economic benefits are important to estimate as the financial attractiveness of the project, which include the electricity generated and revenue from Certified Emission Reduction (CER). This study aims (1) to estimate the potential GHGs emissions produced by the Kawatuna landfill before PLTBg project, (2) to estimate the potential GHGs emissions reduction due to the project, (3) to calculate the potential CER that can be obtained from the project. This study employs Clean Development mechanism (CDM) AMS-III.G method to estimate the potential GHGs reduction and a simple quantitative analysis to calculate the potential CER of the project. The results show that based on the BAU Scenario in 2021, the estimated baseline GHGs emissions is 16.148,74 t CO2e, the potential GHGs reduction after the project would reach 61,40% of the total GHGs emissions generated and the range of potential CER would be from 28.595.318 IDR to 72.329.334 IDR. From 2021 to 2030, total present value of CER would reach 563.358.389 IDR. Keywords: CDM, CER, GHG Emissions, Kawatuna, PLTBg ABSTRAK Pemerintah Kota Palu berencana menghidupkan kembali proyek pembangkit listrik tenaga biogas (PLTBg) di TPA Kawatuna yang sempat beroperasi pada tahun 2013. Informasi mengenai manfaat yang akan diperoleh dari sudut pandang ekonomi dan lingkungan adalah penting bagi pengambil keputusan. Salah satu manfaat lingkungan yaitu potensi reduksi emisi gas rumah kaca (GRK) oleh proyek PLTBg. Manfaat ekonomi penting untuk diestimasi sebagai daya tarik finansial dari proyek, di antaranya berasal dari nilai potensi energi listrik yang dihasilkan dan penerimaan proyek dari Certified Emission Reduction (CER). Tujuan penelitian ini adalah (1) mengestimasi potensi emisi GRK yang dihasilkan oleh TPA Kawatuna sebelum implementasi proyek pemulihan gas metana, (2) mengestimasi potensi reduksi GRK dari proyek tersebut, (3) menghitung potensi nilai CER yang dapat dihasilkan dari proyek tersebut. Penelitian ini menggunakan metode CDM AMS-III.G untuk mengestimasi potensi reduksi GRK dan menggunakan kuantitatif sederhana untuk mengestimasi nilai CER proyek. Hasil penelitian menunjukkan melalui Skenario BAU pada tahun 2021, potensi emisi GRK sebelum adanya proyek adalah 16,148,74 t CO2e dan potensi reduksi GRK setelah adanya proyek mencapai 61,40% dari total emisi yang dihasilkan. Potensi penerimaan CER proyek pada tahun 2021 berkisar antara Rp 28.595.318 hingga Rp 72.329.334 dan total present value penerimaan CER pada tahun 2021-2030 mencapai Rp 563.358.389. Kata kunci: CDM, CER, Emisi GRK, Kawatuna, PLTBg
