Identifikasi Zona Bahaya untuk Rute Pipa Gas Bawah Laut yang Direncanakan di Pulau Pemping, Kota Batam, Kepulauan Riau
No full textThe installation of underwater gas pipelines in Pemping Island, Batam City, Riau Islands, requires quantitative and qualitative study, which can ensure pipeline safety. This research identifies potential hazards along the installation route using pre-lay survey data from multibeam echosounder (MBES) and side scan sonar (SSS). The interpretation of these data using Geographic Information System (GIS) software identified potential hazards: extreme slopes, sediment types, sandwave areas, and underwater cable crossings. The study results showed that 30% of the total pipeline length crosses areas with extreme slopes (15 areas), 20% crosses areas with potential sediment-type hazards (12 areas), 11% crosses sandwaves areas (1 area), and 2% has the potential to cross underwater cables (1 area). In total, about 48% (±574.13 meters) of the pipeline route crosses areas with combined potential hazards, spread across 15 areas. This information is crucial in planning appropriate protection and mitigation for pipeline installation in the region. It is expected that the findings of this study will assist pipeline installers in anticipating hazards and minimizing potential losses caused by these factors by implementing commonly used pipeline protection methods based on the identified hazards, such as trenching, buckle arrestors, and concrete weight coating.Pemasangan pipa gas bawah laut di Pulau Pemping, Kota Batam, Kepulauan Riau memerlukan kajian kuantitatif dan kualitatif untuk memastikan keamanan dan kelancaran pada saat operasionalnya.

Urban Sustainability in Practice: Analyzing the Implementation of the Low-Carbon City Program in Makassar
Get PDFThe Indonesian government, through Law Number 32 of 2009, emphasizes that a good and healthy environment is a fundamental right of every citizen. Various efforts have been made, including the development of regulations, the "Blue Sky" program, and the use of alternative fuels to reduce air pollution.The city of Makassar, through Regional Regulation Number 4 of 2015 concerning the Makassar City Spatial Plan 2015–2034, integrates concepts such as low-carbon city, green city, and climate mitigation city to create a more comfortable and less polluted environment.This study aims to analyze the implementation of the "Low Carbon City" program in Makassar. Using Van Meter & Van Horn\u27s (1975) theoretical framework with a mixed methods research approach, the findings indicate that in early 2024, the Makassar city government focused on carbon emission reduction by promoting the low-carbon city program. The city government collaborates with universities and NGOs in implementing this initiative. While some programs have already been implemented and others are still in progress, a lack of public awareness campaigns has resulted in low public awareness of the program. Additionally, leadership changes at the local level are feared to hinder the sustainability of the initiative

HA PERAN MODAL SOSIAL DALAM PENGAMBILAN KEPUTUSAN PRODUKSI DAN RELASI PRODUKSI PEMBUDIDAYA RUMPUT LAUT DI DESA PUNAGA KABUPATEN TAKALAR
No full textThis study aims to analyze the role of social capital in production decision-making and the formation of production relations among seaweed farmers in Punaga Village, South Sulawesi. A qualitative approach was employed using participant observation, in-depth interviews, and document analysis. The findings indicate that trust, communal norms, and local social networks are central to seaweed farming practices. Social capital functions as a mechanism for information exchange, access to production inputs, and collective labor arrangements. However, the research also reveals that strong social capital fosters patron client relationships that reinforce the dominance of punggawa/pappalele in controlling capital and distribution channels. Closed social networks produce exclusivity and limit economic mobility for new farmers. These findings suggest that social capital is ambivalent: while it supports social cohesion, it also reproduces structural inequality. Strengthening local institutions and developing more inclusive social capital are essential to promoting independence and equity in aquaculture production systems.This study aims to analyze the role of social capital in production decision-making and the formation of production relations among seaweed farmers in Punaga Village, South Sulawesi.

A STUDY ON THE SOCIAL BACKGROUND OF WOMEN DRUG ADDICTS WITH SPECIAL REFERENCE TO THE MIRIHANA POLICE AREA
No full textDrug addiction is a global issue with severe consequences. Once predominantly linked to men, rising substance abuse among women, especially in Eastern societies like Sri Lanka, has become a concern. This study investigated socio-economic, cultural, and environmental factors influencing female substance abuse in the Mirihana Police area of Colombo District. Using semi-structured interviews with 50 women, the study identified that 42% of participants, aged 28–37, were most vulnerable. Most were Sinhalese (80%), Buddhist (52%), and of low education, with 48% having completed only five years of school. Major contributory causes were economic: husbands not being employed (57%), and financial need resulting in prostitution (12%). The main reasons for initiating drug use were friends (46%) and spouses (24%). The study highlights the need for gender-sensitive interventions, including community education, economic empowerment, and accessible rehabilitation services, to address systemic issues and reduce substance abuse among women in Sri Lanka
Stories, Myths and Rituals: Life in the Mentawai Archipelago in a Globalism Analysis
Get PDFMyths, rituals and life stories are interconnected and conveyed through long-standing oral traditions, making them important cultural assets of indigenous peoples around the world. In the Mentawai Islands, myths and rituals are inseparable from the daily lives of the people. The myths are not only communicated within the community but also revealed to outsiders. This research deviates from earlier literature as it aims to explore the relationship between traditional rituals, life stories, myths and modern dynamics in the different valleys to trace the ancestral claims of land ownership. The study employed a qualitative approach. Data was collected through observation and in-depth interviews with Sikerei (shaman), clan elders and notable clan individuals in the thinly populated watersheds in south Siberut Island, complemented by a literature review. The findings show that various rituals and myths about the life journey of the Mentawai people are important to current values. Extended with a unique culture of body tattoos, botanical knowledge, sago staple food consumption combined with animal protein feasts. It can be concluded that myths have a relationship with their living practices they lived, the formation and strengthening of their cultural identities, belief systems and clan land claims in Mentawai. It suggests their indigenous knowledge can opens up a power to see what is not evident to the average mind and contributes to different shades of feeling and experiences
Comparative Analysis of ARIMA and LSTM Methods for Sea Surface Temperature Forecasting in the Sunda Strait
Get PDFThe Sunda Strait is an important area for Indonesia because it is the main domestic and international transportation route. As a water area, the Sunda Strait has weather conditions that are greatly influenced by sea surface temperature (SST). Crucial SST forecasting is carried out to assist maritime transportation activities. This study aims to compare the performance of the ARIMA and LSTM methods in forecasting SST in the Sunda Strait. The data used in this study are daily SST data for the Sunda Strait from August 20, 2022, to January 1, 2024. The best ARIMA model obtained in this data modeling is ARIMA(1,1,1), where this model has significant overall parameters, the smallest AIC and BIC values, and model diagnostic results that meet the assumptions. Meanwhile, in LSTM modeling, the best combination of hyperparameters obtained is a neuron of 150, an epoch of 150, and a batch size of 32, where this combination produces the lowest MSE value of 0.003799. A comparison of the performance of the ARIMA and LSTM methods is carried out by considering the MAPE values of the training data and test data. The LSTM method is superior to the ARIMA method, with a MAPE value of 0.512% for training data and 0.564 for testing data. The forecasting results using the LSTM method show a similar pattern in both training and testing data. Meanwhile, the forecasting results of the LSTM method for the following 30 periods show a fluctuating pattern throughout the day
