Abstract

Ekosistem mangrove memiliki peran penting dalam melindungi wilayah pesisir, menjaga keanekaragaman hayati, serta menyediakan jasa lingkungan dan ekonomi bagi masyarakat. Penelitian ini bertujuan untuk menganalisis perubahan luasan dan struktur vegetasi mangrove di kawasan Kecamatan Kasemen, Kota Serang, dan mengidentifikasi faktor-faktor yang memengaruhi dinamika ekosistemnya. Penelitian dilakukan pada Oktober 2024 menggunakan pendekatan deskriptif melalui analisis spasial, observasi lapangan, dan wawancara. Perubahan luasan mangrove dianalisis melalui digitasi citra satelit dari tahun 2005 hingga 2023 menggunakan perangkat pemetaan. Struktur vegetasi diamati menggunakan aplikasi berbasis digital untuk mencatat tinggi pohon, diameter batang, jenis mangrove, dan penutupan kanopi. Wawancara semi-terstruktur dilakukan untuk memperoleh informasi mengenai kegiatan rehabilitasi dan kondisi lingkungan dari masyarakat sekitar. Hasil menunjukkan peningkatan luasan mangrove dari 11.294 m² pada tahun 2009 menjadi 65.493 m² pada tahun 2023, dipengaruhi oleh penanaman, regulasi daerah, dan keterlibatan komunitas. Struktur vegetasi didominasi oleh Avicennia marina dengan nilai penting tertinggi 232,51. Nilai kesehatan vegetasi bervariasi, dengan angka tertinggi sebesar 62,72% dan terendah 43,84%. Keberadaan fauna khas mangrove seperti kepiting bakau, ikan gelodok, dan siput mengindikasikan peran ekologis mangrove sebagai habitat utama. Penelitian ini menekankan pentingnya penggabungan analisis spasial dan pemantauan ekologi untuk mendukung pengelolaan mangrove secara berkelanjutan.

Abstract

Indonesia is a maritime country where most of the people are fishermen. Indonesia also has potential seas, but due to unstructured management, poverty still plagues the people around the seas. The blue economy is promoted to protect marine ecosystems from damage and for the welfare of coastal communities. The blue economy needs to be supported by sharia financial instruments for funding so that the blue economy is realized properly, these instruments can use blue sukuk. This study aims to examine how blue sukuk is applied in Indonesia as a basis for strengthening the economy of coastal communities. This study uses literature research by seeking information from several related literatures and is presented qualitatively. The results found that if blue sukuk is issued it will encourage the blue economy program that has been launched by the government, especially for strengthening coastal communities. 1.3 million people in coastal communities are still below the poverty line. The management and protection of marine ecosystems need to be encouraged and there needs to be a supporting financial instrument that can use blue sukuk.

Abstract

At the beginning of its emergence, TikTok was used as an entertainment medium for creation and for showing expression. However over time TikTok innovated in the form of TikTok Shop program which was also supported by attractive features—one of which was live streaming. Live streaming drives the number of TikTok users, especially TikTok shop users. Many competitors required the sellers on TikTok to implement strategies to market their products because marketing is the most important line in a business. There are several studies related to this research, but this research was deliberately written to find out how the sales strategy in TikTok which has been widely used and studied based on conventional and sharia marketing strategy. This research is a library research concentrating data sources on books, articles, journals, and etc. TikTok shop uses a marketing mix promotion strategy by using product strategy, pricing strategy, distribution strategy, and promotion strategy. Sales on TikTok also applies sharia marketing theory: the four characteristics, namely fathonah, amanah, shiddiq, and tabligh even though not all sellers apply it due to their various religions as well as their understanding of Islam. Therefore future researchers can carry internalization of understanding of the Islamic religion, especially in terms of mu'amalahAt the beginning of its emergence, TikTok was used as an entertainment medium for creation and for showing expression.

Abstract

Grouping data based on similarity in characteristics is commonly applied in various exploratory analyses. The Fuzzy C-Means algorithm offers flexibility through the degree of membership of data points in each cluster, but it is vulnerable to poor cluster center initialization, which increases the risk of getting trapped in local optima. To enhance the performance of Fuzzy C-Means, this study integrates the Particle Swarm Optimization method for determining cluster centers. The evaluation is conducted by comparing Fuzzy C-Means and Fuzzy C-Means-Particle Swarm Optimization across several cluster counts using three internal validation metrics, namely the silhouette coefficient, partition coefficient, and Xie-Beni Index. The results show that Fuzzy C-Means-Particle Swarm Optimization consistently yields higher silhouette coefficient and partition coefficient values, along with lower Xie-Beni Index values, compared to standard Fuzzy C-Means. This indicates that the integration of Particle Swarm Optimization can improve clustering quality in terms of cluster compactness and separation. This hybrid approach demonstrates significant potential in complex data clustering scenarios.

Abstract

Background: Adolescents generally have good physical and mental health. However, due to various disturbances, they are vulnerable to mental health issues. Mental health has become a global issue, including in Indonesia, affecting nearly 350 million people worldwide (WHO, 2023). Objective: To examine the influence of body weight, psychological resilience, emotional state, self-confidence, academic performance, and social support on adolescent mental health.Methods: This study used a descriptive approach with an ex post facto design. The sample consisted of 89 respondents. Data were collected using a questionnaire, and multiple linear regression analysis was employed. Results: Among the adolescents surveyed, 12 (13.5%) had abnormal mental health, 19 (21.3%) were classified as borderline, and 58 (65.2%) had normal mental health. Regarding body weight, 14 (15.7%) were underweight, 59 (66.3%) had normal weight, and 16 (18%) were overweight. Psychological resilience levels were low in 14 respondents (15.7%), moderate in 46 (51.7%), and high in 29 (32.6%). Emotional state analysis showed that 13 respondents (14.6%) had abnormal emotional conditions, 19 (21.3%) were borderline, and 57 (64%) were normal. Self-confidence levels were low in 12 respondents (13.5%), moderate in 72 (80.9%), and high in 5 (5.6%). In terms of academic performance, 74 (83.1%) had adequate grades, 12 (13.5%) had good grades, and 3 (3.4%) had excellent grades. Social support was low for 11 respondents (12.4%), moderate for 69 (77.5%), and high for 9 (10.1%). All variables showed statistically significant results (p-value: 0.000 < 0.05), indicating a relationship between body weight, psychological resilience, emotional state, self-confidence, and social support with adolescent mental health among middle school students in Cikulur District. Among these factors, emotional state exhibited the strongest correlation with mental health, as evidenced by a Pearson correlation value of 0.980.Conclusion: The study indicates that body weight, psychological resilience, emotional state, selfconfidence, and social support are significantly related to adolescent mental health. Recommendations: Adolescents should enhance their social interactions and engage in positive activities within their environment. Additionally, they should set clear goals for their future aspirations
