UPAYA PEMERINTAH INDONESIA DALAM MENGATASI RESIKO KERUSAKAN LINGKUNGAN SEBAGAI DAMPAK PEMINDAHAN IBU KOTA NEGARA
Authors: Ramadhani Rahmah , Djuyandi Yusa 
Published: March 2024

Pemindahan ibu kota negara Indonesia telah ditetapkan untuk dipindahkan ke Kalimantan Timur, tepatnya di kabupaten Penajam Paser dan Kutai Kartanegara. Latar belakang pemindahan tersebut adalah untuk meminimalisir risiko bencana dan beban kepadatan wilayah DKI Jakarta, serta pemindahan dilakukan ke lokasi tengah wilayah Indonesia dengan lahan yang masih banyak untuk dikembangkan. Namun begitu, kebijakan tersebut menuai pro dan kontra dari berbagai kalangan. Untuk itu, tulisan ini bertujuan untuk menganalisis isu pemindahan IKN mengenai dampak serta peran pemerintah dalam mengatasi kerusakan yang diakibatkan. Metode yang digunakan dalam analisis ini adalah kualitatif deskriptif dengan studi literatur yang memandang peran pemerintah berdasarkan perspektif Keynesian dan penelitian yang memanfaatkan berita di media. Pemindahan IKN mempengaruhi aspek ekonomi, politik, dan yang terutama adalah lingkungan. Beban kerusakan yang ditanggung lingkungan Kalimantan Timur disebabkan oleh pembukaan lahan besar-besaran untuk pembangunan IKN yang meliputi deforestasi. Berdasarkan perspektif Keynesian, kontribusi pemerintah atau keberadaan negara bertujuan untuk maksimalisasi pemanfaatan sumber daya dan optimalisasi perekonomian. Oleh karena itu, salah satu upaya pemerintah dalam mengatasi resiko pemindahan IKN, namun secara bersamaan memanfaatkan sumber daya dan sebagai upaya pemerataan adalah membangun dengan konsep Forest City. The relocation of the capital city of Indonesia has been determined to be moved to East Kalimantan, precisely in the districts of Penajam Paser and Kutai Kartanegara. The background of the relocation is to minimize disaster risk and the burden of the density of the DKI Jakarta area, and the relocation is carried out to a central location in the Indonesian territory with a lot of land to be developed. However, this policy reaps the pros and cons of various groups. For this reason, this paper aims to analyze the issue of transferring IKN (the capital city of Indonesia) regarding the impact and role of the government in overcoming the damage caused. The method used in this analysis is descriptive qualitative with literature study and research that utilizes news in the media. The migration of IKN affects economic, political, and above all environmental aspects. The burden of damage to the environment in East Kalimantan is caused by massive land clearing for IKN development which includes deforestation. Based on the Keynesian perspective, the contribution of the government or the existence of the state aims to maximize the use of resources and optimize the economy. Therefore, one of the government's efforts in overcoming the risk of moving the IKN, but at the same time utilizing resources and as an equalization effort is to build with the Forest City concept.

Artikel ini bertujuan untuk membuktikan adanya proses sekuritisasi dalam konflik Papua di era Kepresidenan Joko Widodo (terutama 2014-2018). Fokus utama penelitian ini adalah pendekatan keamanan yang didominasi oleh Indonesia terhadap permasalahan Papua, khususnya perubahan kebijakan dalam menangani KKB di Papua pasca-Reformasi melalui kerangka pikir sekuritisasi. Dengan menggunakan metode kualitatif, artikel ini menunjukkan perubahan yang signifikan secara yuridis, terutama dalam penggunaan aparatus keamanan negara dalam menangani KKB di Papua saat ini. Namun demikian, penerapan kebijakan baru juga menunjukkan tumpang tindih dan kontradiktif, menjadikan situasi konflik di Papua hingga kini masih tidak pasti. This article aims to demonstrate the securitization processes within the Papua conflict during the presidency of Joko Widodo, particularly focusing on the years 2014-2018. The primary focus of this research is Indonesia's security-oriented approach to the Papua issue, specifically examining policy changes in addressing the Free Papua Movement (KKB) post-Reformasi through the securitization framework. Utilizing a qualitative method, the article illustrates significant juridical changes, especially in the use of state security apparatus in handling the current KKB situation in Papua. However, the implementation of new policies also shows overlap and contradiction, leaving the conflict situation in Papua uncertain to this day.
Study on the Modification and Properties of Silk Sericin Protein/Nano-Titanium Dioxide Composite for Textile Applications
Authors: Yang Chen , Lin Yanping , Zhang Xiangai , Zhu Chunyan 
Published: March 2024

Abstract
Silk sericin protein is a natural high-molecular-weight compound that contains eighteen types of amino acids. It is non-toxic, biodegradable, and biocompatible, with simple preparation methods and low cost. It finds widespread application in functional clothing, medical and pharmaceutical fields, tissue engineering, and more. Nano-titanium dioxide, on the other hand, possesses non-toxic, self-cleaning, antibacterial, and deodorizing properties. To develop multifunctional textiles with deodorization, UV protection, and good thermal and mechanical properties, this study utilized a compounding method to modify citric acid-pre-treated cotton fabrics through a two-dipping and two-padding process using a blend finishing solution of silk sericin protein and nano-titanium dioxide. Observations of the microstructure before and after fabric finishing, along with evaluations of deodorization, UV protection, and thermal properties, revealed that controlling the proportion of the silk sericin protein/nano-titanium dioxide blend finishing solution can result in a smooth surface of the modified cotton fabric. This modification not only enhances the fabric’s UV protection and tensile strength but also improves its thermal properties while imparting certain deodorization capabilities. Comprehensive analysis concludes that using silk sericin protein and nano-titanium dioxide for modifying cotton fabric to prepare multifunctional textiles with deodorization, UV protection, and good thermal and mechanical performance is feasibly viable.
Amend: an integrated platform of retracted papers and concerned papers
Authors: Li Menghui , Chen Fuyou , Tong Sichao , Yang Liying , Shen Zhesi 
Published: March 2024

Abstract

Purpose
The notable increase in retraction papers has attracted considerable attention from diverse stakeholders. Various sources are now offering information related to research integrity, including concerns voiced on social media, disclosed lists of paper mills, and retraction notices accessible through journal websites. However, despite the availability of such resources, there remains a lack of a unified platform to consolidate this information, thereby hindering efficient searching and cross-referencing. Thus, it is imperative to develop a comprehensive platform for retracted papers and related concerns. This article aims to introduce “Amend,” a platform designed to integrate information on research integrity from diverse sources.

Design/methodology/approach
The Amend platform consolidates concerns and lists of problematic articles sourced from social media platforms (e.g., PubPeer, For Better Science), retraction notices from journal websites, and citation databases (e.g., Web of Science, CrossRef). Moreover, Amend includes investigation and punishment announcements released by administrative agencies (e.g., NSFC, MOE, MOST, CAS). Each related paper is marked and can be traced back to its information source via a provided link. Furthermore, the Amend database incorporates various attributes of retracted articles, including citation topics, funding details, open access status, and more. The reasons for retraction are identified and classified as either academic misconduct or honest errors, with detailed subcategories provided for further clarity.

Findings
Within the Amend platform, a total of 32,515 retracted papers indexed in SCI, SSCI, and ESCI between 1980 and 2023 were identified. Of these, 26,620 (81.87%) were associated with academic misconduct. The retraction rate stands at 6.64 per 10,000 articles. Notably, the retraction rate for non-gold open access articles significantly differs from that for gold open access articles, with this disparity progressively widening over the years. Furthermore, the reasons for retractions have shifted from traditional individual behaviors like falsification, fabrication, plagiarism, and duplication to more organized large-scale fraudulent practices, including Paper Mills, Fake Peer-review, and Artificial Intelligence Generated Content (AIGC).

Research limitations
The Amend platform may not fully capture all retracted and concerning papers, thereby impacting its comprehensiveness. Additionally, inaccuracies in retraction notices may lead to errors in tagged reasons.

Practical implications
Amend provides an integrated platform for stakeholders to enhance monitoring, analysis, and research on academic misconduct issues. Ultimately, the Amend database can contribute to upholding scientific integrity.

Originality/value
This study introduces a globally integrated platform for retracted and concerning papers, along with a preliminary analysis of the evolutionary trends in retracted papers.
Accuracy of the Copernicus High-Resolution Layer Forest Type (HRL FTY) assessed with domestic NFI sampling plots in Poland

Published: March 2024

Abstract
Over the past years, several remote sensing maps of land cover have been produced, but they still exhibit certain differences compared to the real land use that reduce their value for climate and carbon cycle modelling as well as for national estimates of forest carbon stocks and their change. This paper outlines a straightforward framework for evaluating map accuracy and estimating uncertainty in land cover area, specifically for forest-related land cover maps in Poland for the year 2018.
The study compares stratified field-based data from the National Forest Inventory (NFI) with remote sensing data on forest variables, at the pixel level, in order to identify suitable methods for accuracy and area uncertainty estimation. Additionally, the paper introduces and presents a variety of accuracy metrics applicable to assess overall uncertainties in GHG inventories.
The results indicate that the High-Resolution Layer Forest Type (HRL FTY) product (part of the broader Copernicus Land Monitoring Service [CLMS] portfolio), assessed using NFI field-based information, achieved an overall accuracy (OA) of 69.2%. This metric varies among particular nature protection forms, with the highest observed ones in Natura 2000 sites of 70.45%. The primary source of map errors was associated with distinguishing between broad-leaved and coniferous forest areas. Improving future maps necessitates more precise differentiation between species to better support national forest monitoring systems for the purpose of greenhouse gas (GHG) inventories where information on the spatial distribution and variability of forests sources, biodiversity assessment, threat prevention, estimation of carbon content is becoming an important part of the associated reporting system.

Divorce in the city of Pekalongan is becoming a trend. The divorce rate is always increasing, even during the covid-19 pandemic and post pandemic. This paper intends to develop an appropriate formulation of mublah marriage guidance to prevent divorce in the city of Pekalongan, by emphasizing the understanding of the mubadalah concept through 5 pillars of marriage: (a) commitment to a strong bond of promise as a mandate from Allah (mitsaq ghalizh), (b) the principle of in pairs and mutually (zawaj), (c) mutual comfort behavior (taradh), (d) treat each other well (muasyaroh bil ma'ruf), (e) the habit of mutual discussion together (deliberation). The purpose of this study was to obtain the right formulation of mubadalah marriage guidance to prevent divorce. This study uses the Research and Development method, with three tests, (1) expert judgement (rational test), with valid results (model can be used), (2) limited scale trial (empirical test) with effective results in increasing understanding of the concepts of mubadalah for prospective bridal couples, and (3) broad-scale trial with effective results increases understanding of the concept of mubadalah for prospective bridal couples. The result of this research is that the formulation of mubadalah marriage guidance is found to be effective in increasing the understanding of the mubadalah concept in the prospective bride and groom, preventing divorce and forming a good (sakinah) family. The results of the limited trial and the effective broad-scale trial were both effective, as seen from the Wilcoxon statistical test which was declared significant (probability < 0.05).
