Abstract

Abstract: This study examines how Tenaganita, a Malaysian local non-governmental organisation, deployed transnational advocacy network (TAN) strategies to compel the United States Customs and Border Protection (CBP) to issue a Withhold Release Order (WRO) against Sime Darby Plantation, the world’s largest producer of certified sustainable palm oil, between 2020 and 2023. Using a qualitative descriptive design based on documentary study, the research applies Keck and Sikkink’s framework of information, symbolic, leverage, and accountability politics, together with the boomerang pattern. The findings show that the forced-labour conditions at Sime Darby satisfied all eleven indicators defined by the International Labour Organization, while domestic enforcement and voluntary RSPO certification both failed. Tenaganita gathered grassroots evidence, transferred it to the Hong Kong-based NGO Liberty Shared for translation into a regulatory petition, and amplified it through investigative journalism that reframed a technical compliance issue as a global moral controversy. The integration of the four strategies converted moral pressure into a coercive sanction, culminating in roughly RM82 million in recruitment-fee reimbursement to more than 34,000 workers before the WRO was revoked in February 2023. Keywords: accountability politics; boomerang pattern; forced labour; transnational advocacy networks; withhold release order.   Abstrak: Studi ini mengkaji bagaimana Tenaganita, sebuah organisasi non-pemerintah lokal Malaysia, menerapkan strategi jaringan advokasi transnasional (TANs) untuk mendorong United States Customs and Border Protection (CBP) menerbitkan Withhold Release Order (WRO) terhadap Sime Darby Plantation, produsen minyak sawit berkelanjutan bersertifikat terbesar di dunia, pada 2020–2023. Dengan pendekatan kualitatif berdesain deskriptif berbasis studi dokumentasi, penelitian ini menerapkan kerangka Keck dan Sikkink tentang politik informasi, simbolis, leverage, dan akuntabilitas, beserta pola bumerang. Temuan menunjukkan bahwa kondisi kerja paksa di Sime Darby memenuhi seluruh sebelas indikator yang ditetapkan Organisasi Buruh Internasional, sementara penegakan hukum domestik dan sertifikasi sukarela RSPO sama-sama gagal. Tenaganita mengumpulkan bukti akar rumput, mentransfernya kepada LSM berbasis Hong Kong, Liberty Shared, untuk diterjemahkan menjadi petisi regulatif, dan memperbesarnya melalui jurnalisme investigatif yang membingkai ulang persoalan kepatuhan teknis menjadi kontroversi moral global. Integrasi keempat strategi tersebut mengonversi tekanan moral menjadi sanksi koersif, yang berpuncak pada pengembalian biaya perekrutan sekitar RM82 juta kepada lebih dari 34.000 pekerja sebelum WRO dicabut pada Februari 2023. Kata kunci: kerja paksa; politik akuntabilitas; pola bumerang; jaringan advokasi transnasional; withhold release order.

Abstract

Abstract: The research findings show that ecological inequality in the e-waste trade operates as a mechanism for producing human insecurity. Through environmental cost-shifting, appropriation of environmental space, and underdevelopment, the ecological burden transferred to Ghana develops into a critical and pervasive threat to the human vital core, thereby disrupting the environmental security, health security, and economic security of local communities. Thus, the e-waste trade not only reproduces global ecological inequality, but also reproduces multidimensional insecurity at the human level. Keywords: e-waste; Ghana; Ecologically Unequal Exchange; Human Security; Multidimensional Insecurity   Abstrak: Temuan penelitian menunjukkan bahwa ketimpangan ekologis dalam perdagangan e-waste beroperasi sebagai mekanisme produksi insekuritas manusia. Melalui environmental cost-shifting, appropriation of environmental space, dan underdevelopment, beban ekologis yang dipindahkan ke Ghana berkembang menjadi ancaman yang bersifat critical adan pervasive terhadap vital core manusia sehingga mengganggu environmental security, health security, dan economic security masyarakat. Dengan demikian, perdagangan e-waste tidak hanya mereproduksi ketimpangan ekologis global, tetapi juga mereproduksi insekuritas multidimensional pada tingkat manusia.

Abstract

Abstract: This study examines Indonesia's layered economic diplomacy strategy in maintaining its sovereign nickel downstreaming policy following the adverse World Trade Organization (WTO) DS592 ruling. Utilizing a qualitative approach with a descriptive-analytical design, this research evaluates the pivotal timeline of 2022–2026 to capture post-dispute dynamics, institutional adaptations, and domestic governance digitalizations. Data were gathered through documentary research from official WTO dispute archives, ministerial performance reports, and credible macroeconomic publications. The findings demonstrate that Indonesia successfully protected its industrial policy space from external interventions by synergizing three diplomatic pillars: leveraging multilateral institutional paralysis through tactical legal maneuvers ("appealing into the void"), isolating bilateral trade frictions within the IEU-CEPA negotiations alongside the establishment of an Ad Hoc Joint Task Force, and aggressively locking in physical foreign direct investment for high-value smelter ecosystems from East Asian partners. Furthermore, this policy space was domestically institutionalized through the integration of the SIMBARA digital governance system to optimize state revenue and resource transparency. In conclusion, this empirical phenomenon challenges liberal institutionalism’s core assumption of automatic compliance by proving that a Global South middle power can effectively counter multilateral regulatory pressures and shift from a traditional raw material supplier to a sovereign industrialized nation by utilizing critical mineral leverage. Keywords: Critical Minerals, Economic Diplomacy, WTO Dispute, Resource Nationalism, Policy Space   Abstrak: Penelitian ini mengkaji strategi diplomasi ekonomi berlapis Indonesia dalam mempertahankan kebijakan kedaulatan hilirisasi nikel pasca putusan sengketa Organisasi Perdagangan Dunia (World Trade Organization/WTO) DS592 yang merugikan Indonesia. Penelitian ini menggunakan pendekatan kualitatif dengan desain deskriptif-analitis untuk menganalisis periode krusial 2022–2026 guna menangkap dinamika pascasengketa, adaptasi kelembagaan, dan digitalisasi tata kelola domestik. Data diperoleh melalui studi dokumentasi yang bersumber dari arsip resmi sengketa WTO, laporan kinerja kementerian, serta berbagai publikasi makroekonomi yang kredibel. Hasil penelitian menunjukkan bahwa Indonesia berhasil mempertahankan ruang kebijakan (policy space) industri nasional dari intervensi eksternal melalui sinergi tiga pilar diplomasi, yaitu pemanfaatan kelumpuhan institusional WTO melalui manuver hukum taktis berupa appealing into the void, isolasi friksi perdagangan bilateral melalui perundingan Indonesia-European Union Comprehensive Economic Partnership Agreement (IEU-CEPA) dan pembentukan Ad Hoc Joint Task Force, serta penguncian investasi asing langsung (foreign direct investment/FDI) secara agresif untuk pengembangan ekosistem smelter bernilai tambah tinggi dari mitra Asia Timur. Lebih lanjut, ruang kebijakan tersebut diinstitusionalisasikan secara domestik melalui integrasi sistem tata kelola digital SIMBARA guna mengoptimalkan penerimaan negara dan meningkatkan transparansi pengelolaan sumber daya. Kesimpulannya, fenomena empiris ini menantang asumsi utama neoliberalisme institusional mengenai kepatuhan otomatis terhadap rezim internasional dengan menunjukkan bahwa kekuatan menengah dari Global South mampu secara efektif menghadapi tekanan regulasi multilateral dan bertransformasi dari pemasok bahan mentah tradisional menjadi negara industri yang berdaulat melalui pemanfaatan daya ungkit mineral kritis. Kata kunci: Mineral Kritis, Diplomasi Ekonomi, Sengketa WTO, Nasionalisme Sumber Daya, Ruang Kebijakan.

Abstract

Abstract: This article presents a systematic literature review regarding early Christian pedagogical strategies and their implications for contemporary faith-based education. The study addresses the issue that modern religious education often suffers from cognitive reductionism—a tendency to treat faith instruction merely as a transfer of doctrine—while the dimensions of character formation, liturgical participation, communal spirituality, and the educator's role as a role model receive insufficient attention. Employing a systematic literature review approach and thematic synthesis, the article analyzes primary and secondary sources covering the *Didache*, the *Apostolic Tradition*, catechesis, baptismal initiation, mystagogy, the Eucharist, liturgy, and contemporary Christian religious education theory. The findings indicate that early Christian pedagogy rested on five key pillars: catechesis as identity formation, mystagogy as reflection on the experience of faith, liturgy as a learning space, the educator as a moral model, and the integration of Scripture, doctrine, and community. The discussion emphasizes that the early church did not separate knowledge from practice, ritual from education, or the teacher from the witness of their life. Consequently, contemporary faith-based education needs to shift from an instructional model toward one that is formative, participatory, and mystagogical. This article offers a conceptual framework that Christian schools, churches, theological institutions, and faith communities can use to design curricula integrating doctrine, liturgy, service, reflection, and character formation. Keywords: early Christian pedagogy; catechesis; mystagogy; *Didache*; liturgy; faith-based education; Christian education; systematic literature review   Abstrak: Artikel ini menyajikan tinjauan literatur sistematis mengenai strategi pedagogis Kekristenan awal dan implikasinya bagi pendidikan berbasis iman kontemporer. Kajian ini berangkat dari persoalan bahwa pendidikan agama masa kini sering mengalami reduksi kognitif, yaitu kecenderungan menempatkan pengajaran iman sebagai transfer doktrin, sementara dimensi pembentukan karakter, partisipasi liturgis, spiritualitas komunal, dan keteladanan pendidik kurang memperoleh perhatian proporsional. Dengan menggunakan pendekatan Systematic Literature Review dan sintesis tematik, artikel ini menganalisis sumber-sumber primer dan sekunder yang membahas Didache, Tradisi Apostolik, katekese, inisiasi baptisan, mistagogi, Ekaristi, liturgi, serta teori pendidikan agama Kristen kontemporer. Hasil kajian menunjukkan bahwa pedagogi Kekristenan awal dibangun atas lima pilar utama: katekese sebagai pembentukan identitas, mistagogi sebagai refleksi pengalaman iman, liturgi sebagai ruang belajar, pendidik sebagai model moral, dan integrasi Kitab Suci, doktrin, serta komunitas. Pembahasan menegaskan bahwa gereja mula-mula tidak memisahkan pengetahuan dari praktik, ritus dari pendidikan, atau guru dari kesaksian hidup. Karena itu, pendidikan berbasis iman kontemporer perlu bergerak dari model instruksional menuju model formatif, partisipatif, dan mistagogis. Artikel ini menawarkan kerangka konseptual yang dapat digunakan oleh sekolah Kristen, gereja, lembaga pendidikan teologi, dan komunitas iman untuk merancang kurikulum yang mengintegrasikan doktrin, liturgi, pelayanan, refleksi, dan pembentukan karakter. Kata kunci: pedagogi Kekristenan awal; katekese; mistagogi; Didache; liturgi; pendidikan berbasis iman; Christian education; systematic literature review

Abstract

Abstract: Mathematical problem-solving skills (KPPM) are one of the essential skills for students in the 21st century. However, in reality, these skills among Phase E students at UNP Pembangunan Laboratorium High School remain low. One instructional model considered effective in addressing this issue is the Creative Problem Solving with GeoGebra (CPS) model. The purpose of this study is to describe the development of students’ mathematical problem-solving skills during the learning process using the CPS model with the aid of GeoGebra, as well as to determine whether there is a difference in outcomes compared to students who participate in traditional, technology-free instruction. This study employs a quasi-experimental design and a descriptive analysis using a non-equivalent post-test-only control group design. The population for this study consisted of Phase E students for the 2025/2026 academic year at UNP Pembangunan Laboratorium High School. The sample was selected using simple random sampling, with class X E3 serving as the experimental class and class X E2 as the control class. The instruments used were quizzes and the KPMM test. The results of the analysis showed an increase in students’ KPMM scores in the experimental class, and the results of the hypothesis test indicated that students taught using the CPS model aided by GeoGebra performed better than those using the direct instruction model in solving mathematical problems. Keywords: Mathematical Problem Solving Ability; Creative Problem Solving; GeoGebra.   Abstrak: Kemampuan pemecahan masalah matematis (KPMM) ialah salah satu kemampuan yang penting dimiliki siswa di abad 21.

Abstract

Abstract: Insect diversity plays a vital role in maintaining ecosystem balance, particularly in plantation ecosystems that are influenced by variations in vegetation structure and habitat conditions. This study aims to analyze insect diversity across various plantation types in Sari Tani Village, Wonosari District, Boalemo Regency, Gorontalo Province. A descriptive quantitative method was employed, with sampling conducted using pitfall traps and light traps. Observations were conducted at three stations: uncultivated shrubland, mixed plantation (cloves, coconuts, and bananas), and a citrus plantation. Data analysis was performed using the Shannon-Wiener diversity index (H'), Pielou's evenness index (E), and Simpson's dominance index (D). The results revealed a total of 606 individual insects across 8 orders and 17 families, encompassing various ecological roles including predators, decomposers, pollinators, pests, and bioindicators. The order Hymenoptera, specifically from the family Formicidae, was the most dominant group found, with the species Lasius niger exhibiting the highest number of individuals. The Shannon-Wiener diversity index (H') values across all stations fell into the moderate category. Station II, located in the mixed plantation, had the highest diversity value among the other stations. The dominance index values across all stations were low; in contranst the evenness index ranged from moderate to high, indicating that the insect community at the study site is relatively stable with a fairly even distribution of individuals among species. Overall, differences in plantation types significantly influence the community structure and insect diversity in Sari Tani Village. Keywords: Insects, Diversity, Community Structure, Plantation Types, Sari Tani   Abstrak: Keanekaragaman serangga memiliki peran penting dalam menjaga keseimbangan ekosistem, terutama pada ekosistem perkebunan yang dipengaruhi oleh perbedaan struktur vegetasi dan kondisi habitat.

Abstract

Abstract: This research investigates how product quality, pricing, and consumer trust affect the online buying interest of adolescents using the Shopee platform in Medan. A quantitative methodology with a causal-associative design was utilized for this investigation. The target population comprised youth aged 17–20 who had experience shopping on Shopee, from which 100 participants were chosen via a purposive sampling approach. Data gathered through questionnaires were subsequently processed using multiple linear regression analysis via SPSS. The empirical evidence demonstrates that, partially, price exerts a positive and statistically significant impact on purchase intention, whereas product quality and trust show no significant influence. Concurrently, all three independent variables collectively affect buying interest. The coefficient of determination (R²= 0.821) reveals that 82.1% of the variance in adolescent purchase intention is accounted for by these factors, with the other 17.9% driven by external variables not examined here. Keywords: Product Quality, Price, Trust, Purchase Intention, Shopee.   Abstrak: Penelitian ini mengkaji bagaimana kualitas produk, penetapan harga, dan kepercayaan konsumen memengaruhi minat berbelanja daring remaja yang menggunakan platform Shopee di Medan.
