Upaya Perlindungan Hukum Terhadap Penyalahgunaan Bantuan Sosial: Aplikasi Kawal.Id Sebagai Platform Kelompok Marginal Terdampak Covid-19 di Indonesia

Abstract Since Indonesia was hit by the Covid-19 Pandemic, the government has tried to optimize the economic life of the community, especially marginal groups by simultaneously providing social assistance. The reality of the increasing misuse of social assistance to marginal groups occurs due to the lack of application of the principles of accountability and transparency from the government reflecting legal injustice. This is in line with recipients of social assistance who are not well-targeted, corruption, until the social assistance is not given to the community regarding the right to equal life insurance. This paper describes the solution to the problem as an effort to protect the law through the Kawal.Id application with a case approach. The analysis shows that the Kawal.Id application is oriented towards optimizing data validation of marginalized groups in an efficient manner. In the implementation process, harmonization and collaboration between students and the Indonesian National Police is a key mechanism. So that the goal that is concentrated by the use of application ideas can be an answer to the gloomy existence of social assistance abuse that robs marginalized groups of rights during the Covid-19 pandemic. Keywords: Abuse of Social Assistance; Kawal.Id; Marginal Group.   Abstrak Sejak Indonesia dilanda Pandemi Covid-19 pemerintah berupaya mengoptimalkan kehidupan ekonomi masyarakat khususnya kelompok marginal dengan melakukan pemberian Bantuan Sosial (bansos) secara simultan.

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Edukasi Pengelolaan Sampah Rumah Tangga Melalui Unit Usaha Bank Sampah

Kegiatan pengabdian ini dilatarbelakangi oleh permasalahan mitra terkait pengelolaan sampah rumah tangga. Sampah merupakan salah satu masalah lingkungan yang dihadapi oleh banyak masyarakat. Tidak tepatnya pengelolaan sampah dapat memberikan dampak negatif terhadap lingkungan dan masyarakatnya. Upaya pengelolaan sampah melalui bank sampah telah dicanangkan oleh Pemerintah Kab. Majene sejak setahun terakhir, namun sampai saat ini belum terlihat banyak pos-pos bank sampah di beberapa wilayah, termasuk di Desa Ulidang Kec, Temmarodo. Prinsip utama bank sampah desa adalah memanfaatkan sampah dengan cara yang bijak dan memberikan manfaat ekonomi dengan 3R (reduce, reuse, dan recycle). Konsep bank sampah mirip dengan bank konvensional tetapi yang ditabung bukan uang melainkan sampah kering yang sudah dipilah. Agar program dari pemerintah daerah ini dapat terlaksana dengan baik maka diperlukan andil dari berbagai pihak termasuk perguruan tinggi. Oleh karena itu, pelatihan edukasi: pengelolaan sampah rumah tangga melalui unit usaha bank sampah sangat perlu dilaksanakan. Target dari pelaksanaan kegiatan ini yaitu: a) meningkatnya pemahaman masyarakat Desa Ulidang dalam pengelolaan sampah rumah tangga melalui unit usaha bank sampah; b) meningkatnya pemahaman perangkat desa dan Ibu-Ibu PKK dalam mengelola sampah menjadi barang yang bernilai Ekonomi; c) meningkatnya pemahaman masyarakat terhadap digital marketing dan branding produk-produk yang dihasilkan oleh bank sampah; dan d) mendukung kebijakan pemerintah daerah dalam pengelolaan sampah berbasis teknologi dan pemberdayaan masyarakat. Dalam pelaksanaannya, program pengabdian kepada masyarakat kemitraan desa ini dilaksanakan dalam empat tahapan yaitu: a) tahap awal, pada tahap ini dilakukan identifikasi permasalahan mitra yang dilanjutkan dengan sosialisasi rencana pelaksanaan kegiatan; b) tahap persiapan, pembuatan materi pelatihan edukasi pengelolaan sampah rumah tangga, materi pengolahan sampah menjadi barang yang bernilai ekonomi, dan materi edukasi digital marketing, serta branding product; dan c) tahap pelaksanaan, pelaksanaan pelatihan/pembinaan kepada perangkat desa dan Ibu-Ibu PKK; d) tahap akhir, pembuatan laporan akhir program pelatihan edukasi dan publikasi artikel ilmiah
