As a form of commitment to reducing the amount of plastic waste in the environment, DKI Jakarta Province has issued Governor Regulation Number 142 of 2019 concerning the Obligation to Use Environmentally Friendly Shopping Bags in Shopping Centers, Supermarkets and People's Markets. On the roadmap proposed by the United Nations Environment Agency, Governments developing policies will need to verify the existence of valid alternatives before banning plastic bags. However, in this regulation, the type, size, material, price and sales of eco-friendly shopping bags are the responsibility of the business actor. The definition of a reasonable price, type, size, and material of shopping bags provided by business actors in this regulation is not clear and can lead to different perceptions, causing the implementation of this regulation to be ineffective. In this study, the types and price limits of eco-friendly shopping bags were analyzed based on the perception and willingness of the public as consumers to facilitate the implementation of regulations related to the use of eco-friendly shopping bags, especially in DKI Jakarta Province. This study uses a qualitative approach by conducting a survey of 406 female respondents with an age range of 18-40 years who live in DKI Jakarta Province. Conjoint analysis is used to determine preferences for eco-friendly shopping bags using SPSS version 24. Consumers' willingness to pay for eco-friendly shopping bags is analyzed using the Contingent Valuation Methode (CVM) approach. Based on the research results, consumers prefer eco-friendly shopping bags that are made of cloth, can be reused, and prefer to bring or provide them themselves rather than being provided by businesses but paying a fee. According to consumers, material attributes are the most important, followed by environmental and economic attributes. If required to pay, 28% of respondents are willing to pay with higher price than the average estimated price of consumers' willingness to pay (WTP), which is IDR 2,380 a piece. The government can use the results of an analysis of people's preferences and willingness to formulate the policies.
作为对减少环境中塑料垃圾数量的一种承诺，DKI 雅加达省发布了 2019 年第 142 号省长条例，涉及在购物中心、超市和人民市场使用环保购物袋的义务。根据联合国环境署提出的路线图，各国政府在制定政策时需要核实是否存在有效的替代品，然后才能禁止使用塑料袋。不过，在本条例中，环保购物袋的类型、尺寸、材料、价格和销售均由企业行为者负责。该法规中对企业行为者提供的购物袋的合理价格、类型、大小和材料的定义并不明确，可能会导致不同的认识，导致该法规的实施效果不佳。在本研究中，根据公众作为消费者的认知和意愿，分析了环保购物袋的类型和价格限制，以促进环保购物袋使用相关法规的实施，尤其是在 DKI 雅加达省。本研究采用定性方法，对 406 名居住在 DKI 雅加达省、年龄在 18-40 岁之间的女性受访者进行了调查。使用 SPSS 24 版进行联合分析，以确定消费者对环保购物袋的偏好。消费者对环保购物袋的支付意愿采用权变估值法（CVM）进行分析。根据研究结果，消费者更喜欢布制的、可重复使用的环保购物袋，并且更愿意自己携带或提供环保购物袋，而不是由商家提供但支付一定费用。消费者认为，材料属性最重要，其次是环境和经济属性。如果需要付费，28% 的受访者愿意支付高于消费者支付意愿（WTP）平均估计价格的价格，即每件 2,380 印尼盾。政府可以利用人们的偏好和意愿分析结果来制定政策。

This research aims to identify the preceding factors for achieving green competitive advantage, as traditional marketing might not be adequate to cater to this aspect. Therefore, the analysis explores the correlation between the theory of reasoned action and green marketing and how the blending of these concepts affects eco-friendly innovation and, subsequently, green competitive advantage. A quantitative approach was employed to conduct this investigation, using questionnaires gathered through direct visits to 100 coffee shops in and around Jakarta. The sample was selected through purposive non-probability sampling. The collected data were analyzed using SMART PLS.3 software, employing the structural equation model (SEM). The findings highlight that both internal and external orientations exert an impact on green innovation, which, in turn, affects green competitive advantage. However, it should be noted that internal and external environmental orientations do not have a direct impact on green competitive advantage. This research contributes to the field of green marketing by highlighting the crucial role of green innovation in achieving green competitive advantage and establishing the link between environmental orientation and competitive edge. Companies can allocate resources to improve their green innovation efforts, which can strengthen their competitive position in the market. The study provides practical guidance for businesses aiming to enhance their green competitive advantage. However, the identified limitations should prompt researchers and practitioners to consider broader industry and methodology coverage in future investigations.

The development of the industrial sector in Indonesia has increased very rapidly, especially in the textile industry. The increasing number of industries has an impact on the amount of industrial waste. Congo red dye is one of the dyes that are often used in the textile industry. Industrial dye waste needs to be processed so as not to damage the environment because the substances contained are harmful to the environment. One way that can be used to neutralize dye waste is ozone. Ozone can be used in many fields such as oxidation of inorganic/organic compounds and disinfection (or control of pathogens). H2O2 catalyst is used to accelerate the ozonation process. In this research the variables used were ozonation time (0.15,30,45,60 minutes), pH conditions (5,7,9) and the concentration of H2O2(0,2.5,5,7.5,10) % mass. Based on the research, it was found that the longer the ozonation time, the higher the pH value, and the more H2O2 used, the better the ozonation process results, namely the lower the concentration of dyes, COD, and BOD5 contained in the wastewater.

Pemakaian bahan-bahan kimia pada kegiatan praktikum ataupun penelitian di laboratorium tentunya akan menghasilkan air limbah. Air Limbah yang dihasilkan dari laboratorium tergolong limbah berbahaya dan/atau beracun. Berdasarkan zat yang terdapat di dalam air limbah laboratorium secara kolektif serta kurun waktu yang lama apabila langsung dibuang ke badan air akan mencemari lingkungan serta berdampak bagi makhluk hidup disekitarnya. Komposisi limbah laboratorium yang reaktif dan berbahaya karena mengandung logam berat seperti Pb, Fe, Cu dan logam berat lainnya serta COD yang tinggi sehingga sulit terurai di alam. Penelitian ini bertujuan untuk mengolah air limbah laboratorium menggunakan metode Advanced Oxidation Processes (AOPs) dengan pretreatment koagulasi dan adsorpsi. Oleh sebab itu, penelitian ini akan diprioritaskan pada penurunan kadar logam berat Pb, Fe, Cu dengan karbon aktif sebagai adsorben dan penurunan COD menggunakan reagen Fenton. Persentase maksimum penurunan logam berat Pb, Fe dan Cu dengan proses Fenton dilanjutkan dengan proses adsorpsi berturut turut sebesar 95,67%, 99,98% dan 99,93% dengan massa optimum adsorben yang digunakan adalah 1,5 gram. Sedangkan persentase penurunan COD tertinggi tercapai pada rasio molar reagen Fenton 1:1200 yaitu mencapai 99,98%. Sehingga dapat disimpulkan bahwa pengolahan air limbah laboratorium secara terintegrasi melalui serangkaian proses pretreatmen koagulasi dan adsorpsi dilanjutkan dengan reagen Fenton dan adsorpsi secara terintegrasi telah memenuhi baku mutu lingkungan.

After the forest fires in 2014-2016, the Government of Indonesia (GoI) placed the restoration of the peatland ecosystem (RPE) as one of its priority policies in the environmental sector. This study seeks to analyze RPE in Indonesia using a discourse network analysis approach. Researchers utilize Twitter as primary research data. This data was processed with R, rDNA, and Gephi. Researchers found three network patterns that are connected to RPE efforts in Indonesia. First, affiliate networks connect actors and the concepts voiced by the actors. This network involves various actors such as government institutions, civil society organizations, private corporations, universities, research institutes, foreign governments, international organizations, and local citizens. The dominant concept in the affiliate network is peatland restoration and multi-stakeholder collaboration. Second, the actor congruence network assigns Mangrove and Peatland Restoration Agency (Badan Restorasi Gambut dan Mangrove or BRGM) as the dominant and central actors. However, some actors are not connected to the core network and create separate sub-groups. Third, a network of conflicts between actors involving four conflict themes: Government Regulation Number 57/2016 concerning Amendments to Government Regulation Number 71/2014 on Protection and Management of Peatland Ecosystems, peatland conversion, horizontal conflicts between the local community and plantation corporations, and prevention and law enforcement related to forest fires. The researcher recommends BRGM to: (a) strengthen collaborative practices with the various parties involved in RPE; (b) beware in converting peatland so it does not damage the peatland ecosystem landscape; (c) integrate community conflicts with plantation corporations as part of the RPE agenda in Indonesia. The researcher also recommends NGO activists in Indonesia who care about peatlands to continue monitoring and criticizing the RPE process in Indonesia, and fight for local community groups that have been marginalized by the RPE process. Researchers also encourage plantation corporations, both oil palm plantations and industrial timber plantations, to jointly guard RPE in Indonesia by not opening up new land as part of the actual contribution of the Indonesian people to climate change adaptation and mitigation.

ABSTRAKUmbi-umbian merupakan jenis komoditas pertanian yang banyak ditemukan di daerah tropis seperti di Indonesia dan pertumbuhannya tidak menuntut iklim serta kondisi tanah yang spesifik. Umumnya umbi-umbian mengandung sumber karbohidrat terutama pati yang cukup baik untuk menggantikan beras. Dalam rangka mempertahanakan ketahanan pangan nasional diperlukan eksplorasi sumber daya genetik lokal umbi-umbian sebagai sumber bahan makanan lain sekaligus untuk dapat melindungi dan mempertahankan kelestarian sumber daya genetik lokal tanaman umbi-umbian tersebut. Penelitian ini bertujuan untuk mengetahui keanekaragaman dan kemelimpahan sumber daya genetik lokal umbi-umbian di Kecamatan Mijen serta menganalisa potensi sumber daya genetik lokal umbi-umbian dalam menunjang ketahanan pangan nasional di Indonesia. Teknik penelitian menggunakan metode eksplorasi atau jelajah. Data yang telah diperoleh kemudian dianalisis secara deskriptif semi kuantitatif serta ditabulasikan dalam bentuk tabel. Hasil penelitian ini ditemukan 10 jenis sumber daya genetik lokal umbi-umbian antara lain ganyong (Canna edulis Kerr), kimpul (Xanthosoma sagittifolium (L.) Schott), serawak (Colocasia esculenta (L.)

Muka air tanah merupakan salah satu indikator penting degradasi lahan gambut. Sesuai aturan pemerintah, pemanfaatan lahan gambut yang memiliki fungsi budidaya disyaratkan untuk menjaga muka air tanah maksimal 40 cm di bawah permukaan tanah. Dalam upaya untuk mengendalikan degradasi gambut, pemerintah melakukan program restorasi gambut yang salah satunya bertujuan untuk pembasahan gambut dengan membangun sekat-sekat kanal pada lokasi prioritas, termasuk di Kabupaten Kubu Raya. Dalam penelitian ini dilakukan pengukuran muka air tanah di dua lahan pertanian skala kecil milik masyarakat di Desa Madusari, Kecamatan Sungai Raya, Kabupaten Kubu Raya, Provinsi Kalimantan Barat. Desa ini merupakan salah satu desa penerima program restorasi gambut berupa pembangunan sekat kanal. Terdapat dua plot pengukuran yang memiliki tipe sekat kanal yang berbeda, yaitu sekat kanal yang dibagun Dinas Pekerjaan Umum dan sekat kanal yang dibangun Badan Restorasi Gambut. Masing-masing plot terdiri dari enam titik pengukuran muka air tanah, yang mulai diukur sejak bulan Februari sampai Mei 2022. Muka air tanah diukur melalui sumur pantau (piezometer) yang terbuat dari pipa PVC berdiameter sebesar 5 cm yang dibenamkan ke dalam tanah. Selain muka air tanah, sifat fisik gambut yang diukur dalam kegiatan penelitian ini meliputi kedalaman gambut, bobot isi, berat jenis partikel, porositas, permeabilitas serta kadar air gravimetrik dan volumetrik. Data curah hujan diperoleh dari stasiun BMKG terdekat, yaitu Stasiun Supadio, Pontianak.

Sesuai aturan pemerintah, pemanfaatan lahan gambut yang memiliki fungsi budidaya disyaratkan untuk menjaga muka air tanah maksimal 40 cm di bawah permukaan tanah. Dalam upaya untuk mengendalikan degradasi gambut, pemerintah melakukan program restorasi gambut yang salah satunya bertujuan untuk pembasahan gambut dengan membangun sekat-sekat kanal pada lokasi prioritas, termasuk di Kabupaten Kubu Raya. Dalam penelitian ini dilakukan pengukuran muka air tanah di dua lahan pertanian skala kecil milik masyarakat di Desa Madusari, Kecamatan Sungai Raya, Kabupaten Kubu Raya, Provinsi Kalimantan Barat. Desa ini merupakan salah satu desa penerima program restorasi gambut berupa pembangunan sekat kanal. Terdapat dua plot pengukuran yang memiliki tipe sekat kanal yang berbeda, yaitu sekat kanal yang dibagun Dinas Pekerjaan Umum dan sekat kanal yang dibangun Badan Restorasi Gambut. Masing-masing plot terdiri dari enam titik pengukuran muka air tanah, yang mulai diukur sejak bulan Februari sampai Mei 2022. Muka air tanah diukur melalui sumur pantau (piezometer) yang terbuat dari pipa PVC berdiameter sebesar 5 cm yang dibenamkan ke dalam tanah.

Commercial activated carbon is a type of adsorbent commonly used in adsorption processes. However, the use of commercial carbon in wastewater treatment is still limited, due to the scarce availability of precursors and their high cost. Biomass as an activated carbon precursor has been reported to have high efficiency in removing various heavy metals in wastewater. This study aims to review the potential of biomass-based activated carbon to adsorb heavy metals in terms of biomass constituent components, heavy metal removal, and future prospects. The method in this study is a systematic literature review, or SLR, to collect data from online databases such as Google Scholar, PubMed, and ScienceDirect. The results show that biomass-based activated carbon is effective in the removal of heavy metals in various types of wastewater. The removal effectiveness for different types of biomass ranged from 84–99% for Pb2+ ions, 55–92% for Cd2+ ions, 84–99% for Pb2+ ions, 96% for As2+ ions, 80–100% for Cr2+ ions, 25–97% for Fe2+ ions, 50–99% for Ni2+ ions, and 62–98% for Cu2+ ions, and 98% for Ti ions. These results show that heavy metals have different affinities to activated carbon from biomass, from all heavy metals, Fe2+ and Cd2+ ions have the lowest affinity, so the activated carbon used to remove Fe2+ and Cd2+ metals needs to be produced with higher porosity and surface area. The removal of heavy metals using activated carbon from biomass is limited by adsorbent dosage, contact time, solution pH, temperature, initial adsorbate concentration, particle size, and stirring speed. In future research, it is expected that activated carbon from biomass has a high adsorption capacity, is economical cost, is environmentally friendly and can be used on a larger scale.

Akumulasi logam berat pada tanah memberikan dampak yang besar bagi lingkungan seperti dapat mengganggu keseimbangan ekologi, mengurangi kesuburan tanah, mengubah kualitas fisikokimia tanah dan sangat berbahaya bagi kesehatan manusia. Penelitian ini bertujuan untuk menganalisis status logam berat pada tanah dan kemungkinan terjadinya dampak ekologi yang tidak diinginkan pada lingkungan akibat adanya cemaran logam berat pada lahan pertanian Kapaten Malang. Penelitian ini menggunakan metode survey pengambilan contoh tanah dengan jumlah titik lokasi pengambilan contoh tanah sebanyak 123 titik. Analisis yang dilakukan antara lain analisis spasial, geoaccumulation index (I-Geo), polltuion index (PI), the Nemerow integrated pollution index (NIPI), dan potential ecological risk index (RI). Hasil dari penelitian ini menunjukkan bahwa logam Pb, Cd, Co, Ni, Cr, Cu, Mn, Zn dan As terdeteksi hampir di semua lokasi pengambilan contoh tanah pada lahan pertanian Kota Malang. Hasil analisis geoaccumulation index (I-geo), pollution index (PI), the Nemerow integrated pollution index (NIPI) dan potential ecological risk index (RI) menunjukkan hasil yang selaras bahwa logam Cd merupakan sumber utama pencemaran logam berat di lahan pertanian Kota Malang dengan nilai pencemaran yang cukup tinggi sehingga juga memiliki dampak ekologis yang tinggi.
