Strategi Kontraterorisme Iran terhadap ISIS-K: : Antara Kepentingan Keamanan dan Ambisi Geopolitik
Get PDFThe Islamic State of Iraq and Syria – Khorasan Province (ISIS-K) has emerged as a transnational threat in Southwest Asia, posing a significant challenge to Iran’s national security. This article analyzes Iran’s counterterrorism strategy in responding to the presence and operations of ISIS-K in the Khorasan region. Employing a qualitative approach and literature-based analysis, this study draws from policy documents, academic literature, and official statements. The findings reveal that Iran adopts an active defense posture involving intelligence coordination, border security enhancement, and regional cooperation, particularly with Afghanistan and Russia. These strategies are driven not only by domestic security concerns but also by Iran’s geopolitical interest in maintaining regional influence. The study concludes that Iran’s response to ISIS-K reflects an effort to safeguard internal stability while shaping a regional security order aligned with its strategic interests.Strategi kontra-terorisme yang diimplementasikan Republik Islam Iran terhadap Islamic State of Iraq and Syria – Khorasan Province (ISIS-K) selama periode 2020–2024. Latar belakang penelitian ini bermula dari kematian Jenderal Qasem Soleimani pada 3 Januari 2020, yang memicu kekosongan kepemimpinan militer Iran dan membuka peluang bagi ISIS-K untuk meningkatkan aktivitas di perbatasan timur negara tersebut. Eskalasi serangan teror, termasuk bom bunuh diri dan serangan bersenjata di provinsi Sistan dan Baluchestan, mendorong pemerintah Iran merancang kerangka respons yang menggabungkan instrumen Soft Power dan Hard Power. Tujuan utama penelitian adalah memetakan dan menganalisis efektivitas mekanisme Soft Power—meliputi delegitimasi ideologi, diplomasi multilateral, rekonsiliasi lokal, dan mitigasi akar penyebab—serta mekanisme Hard Power, yang mencakup operasi militer ofensif, pertahanan perbatasan, operasi intelijen lintas batas, dan aksi penindakan langsung terhadap sel-sel ISIS-K. Dengan demikian, penelitian bertujuan memberikan gambaran menyeluruh mengenai integrasi kedua pendekatan tersebut dalam menurunkan kemampuan operasional ISIS-K. Analisis data dilakukan melalui kerangka counterterrorism yang memisahkan Soft Power dan Hard Power, kemudian dievaluasi efektivitasnya berdasarkan indikator penurunan jumlah insiden teror, kerusakan infrastruktur, korban jiwa, serta tingkat kerjasama internasional dan lokal.
 
Detection of Trichodina sp. In Nile Tilapia (Oreochromis niloticus) Cultivated inTanjung Bunga Lake, Makassar City
Get PDFTilapia is the favorite freshwater fish that is widely cultivated in Indonesia.The problem experienced by many tilapia farmers is the emergence of disease attacks. Inadequate water quality and high density play a role in causing stress in fish and increasing the risk of disease. Changes in natural conditions such as temperature, pH, and DO (dissolved oxygen) can affect water quality. One of the diseases that often occur in tilapia in aquaculture with poor water quality is diseases caused by ectoparasites. One type of ectoparasite that commonly attacks tilapia is Trichodina sp. This study aims to determine the presence of Trichodina sp. ectoparasite infection in tilapia cultivated in Tanjung Bunga Lake, Makassar City. Sampling using random sampling method with a total sample size of 58 fish. Ectoparasite examination was performed on body surface mucus and gills using a microscope with 400x magnification. Detection results on tilapia samples as many as 58 fish found 50 (86.2%) positive tilapia samples infected with Trichodina sp. ectoparasites, including 40 (80%) positive samples in the body surface mucus and gills, 8 (16%) positive samples only in the gills, and 2 (4%) positive samples only in the body surface mucus. The range of water quality examinations at seven points had temperatures ranging from 29-31°C, pH 6, salinity 0 mg/L, DO 2.24-10.24 mg/L, nitrate 0.0141-0.1857 mg/L, nitrite 0.0451-0.5555 mg/L, and ammonia 0.0028-0.0096 mg/L. The results of this study reveal that farmed tilapia may be infected with the ectoparasite Tricodina sp
Conflict and Compromise, Discourse and Action: Political Ecology in the Complexity of Land Management in Central Kalimantan, Indonesia
Get PDFPeatlands in Mantangai District, Central Kalimantan, have emerged as a site of contention among many stakeholders with differing interests, illustrating the intricacies of natural resource management in Indonesia. This research seeks to examine the contestation process, identify main actors, and comprehend how various forms of knowledge and power influence the results of peatland management. This research employs a case study method with a qualitative approach, incorporating direct observation, in-depth interviews, and document analysis to achieve a thorough knowledge of the dynamics of contestation. The findings indicate three primary viewpoints in peatland management: eco-conservationism exemplified by Mawas Borneo Orangutan Survival Foundation (BOSF), eco-developmentalism illustrated by the government\u27s food estate initiative and oil palm plantation expansion, and eco-populism promoted by Wahana Lingkungan Hidup (WALHI) Central Kalimantan and local communities. This contention leads to multiple underlying conflicts, including tensions between conservation initiatives and resource extraction activities by local communities, discrepancies between governmental development programs and the ecological and social realities, as well as unresolved land disputes and compensation challenges arising from the expansion of oil palm plantations. This study suggests that a more holistic and inclusive approach to peatland management is necessary, taking into account ecological, economic, and socio-cultural factors in a balanced manner. These findings significantly enhance the comprehension of the intricacies of natural resource management and can underpin the formulation of more inclusive and sustainable policies moving forward

Comparison of Basic Statistics and Machine Learning Classification Algorithms in Kalimantan Poverty Prediction with Handling Missing Data
Get PDFPoverty is a crucial development challenge in Indonesia, including in regencies/cities in Kalimantan that require more attention. In reality, poverty is influenced by various factors. Therefore, this research proposes an analysis comparing the accuracy of basic and statistical machine learning models in predicting poverty rates and finding factors that affect poverty rates. The advance of this research is the performance comparison combined with the handling of missing data. The three models proposed in this study are binary logistic regression with backward stepwise selection, random forest, and extremely randomized trees (extra trees). The data used in this study is secondary data taken from the Indonesian Statistics (BPS) of five provinces in Kalimantan, where the pre-processing is done by handling missing data with a k-nearest neighbor (KNN). The results of the poverty prediction analysis show that the binary logistic regression model is the most accurate compared to random forest and extra trees, with a balanced accuracy of 75%. In addition, based on the best model with the highest accuracy, this study also found significant predictor variables that affect the poverty rate of regencies/cities in Kalimantan: population density, average years of schooling, and per capita expenditure on food

Circular Economy Integration in Community-Based Forest Management: A Sustainability Analysis in Indonesia
No full textThis study examines the integration of circular economy principles into community-based forest management (CBFM) collaborative strategies in Indonesia. Using a systematic literature review methodology, we analyzed 25 published studies and policy documents from 2015-2024, focusing on the interface between circular economy and collaborative forest governance. Results reveal that CBFM initiatives incorporating circular principles show enhanced resource efficiency and increased community income compared to conventional approaches. Four key integration models were identified: closed-loop forest product systems, regenerative agroforestry, waste-to-value conversion, and circular value chain partnerships. Critical success factors include adaptive governance mechanisms, multi-stakeholder knowledge platforms, and policy coherence across sectors. Significant implementation barriers persist, including capacity limitations, misaligned incentive structures, and inadequate market access. The study provides a multi-dimensional analytical framework and strategic recommendations for policymakers and practitioners seeking to advance sustainable forest management through circular economy integration in the Indonesian context
