Kota Banda Aceh merupakan salah satu daerah pesisir yang terdampak tsunami. Pasca tsunami pesisir pantai Aceh direkonstruksi dan direhabilitasi kembali. Salah satu sumber matapencaharian masyarakat pesisir pantai adalah lahan tambak yang pada saat bencana tsunami mengalami kerusakan parah. Sehingga tambak menjadi salah satu program prioritas yang dipercepat proses pembangunnannya. Pascatsunami petani tambak mendapat bantuan dari pemerintah dan non pemerintah contohnya seperti bibit ikan dan udang. Pemilihan bibit ikan dan udang yang dibudidayakan petani tambak sangat beragam dan berdasarkan berbagai pertimbangan tertentu. Tujuan penelitian ini adalah untuk mengetahui spesies dan preferensi ikan yang dibudidayakan petani tambak di Kota Banda Aceh. Metode yang digunakan dalam penelitian ini adalah metode purposive sampling dengan teknik pengumpulan data melalui observasi lapangan, studi dokumentasi dan wawancara langsung terhadap petani tambak. Hasil penelitian menunjukkan ada lima spesies ikan yang dibudidayakan petani tambak di Kota Banda Aceh yaitu Chanos-chanos, Oreochromis mossambicus, Lates calcarifer, Oreochromis. niloticus dan Clarias gariepinus. Pertimbangan pemilihan ikan yang dibudidayakan berdasarkan nilai ekonomis, daya tahan terhadap serangan penyakit, reproduksi yang cepat dan kemudahan dalam pemeliharaannya. Ikan yang dibudidayakan di Kota Banda Aceh cukup beragam dengan preferensi tertentu.

Understanding feral cat behavior can be one of the aspects that is necessary for proper management and taking policy action in controlling the cat population. This study aimed to observe the daily activities of feral cats and see the correlation between the number of visitors on cat-to-human interaction at a canteen in IPB University. Observation of cat’s daily behavior was conducted by scan sampling method and cats’ interaction with humans was conducted by ad libitum sampling. Our results showed that self-care (66.27%) dominated the daily behavior of cats followed by negative behavior (20.83%) and affiliative behavior (12.9%). Correlation test showed there was a significant negative correlation between the number of visitors and frequency of affiliative behavior (p = 0.024). The number of visitors also shows a positive correlation to self-care (p = 0.034). No significant correlation between the number of visitors and negative encounters behavior (p = 0.27). The highest frequency value of cat-human interaction was approaching human (A) 28.15%, followed by vocalization (MV) 28.15% and eye contact (KM) 22.71%. Cat-human interaction behavior did not significantly correlate with the number of visitors (p 0.05). Our result implies that the feral cat’s use the canteen as a place to rest, not a place to find food and daily activities and human-cat interactions were specific for each study site. Therefore, in the management of feral cats, it was necessary to pay attention to the conditions of their respective habitats.

The energy source of the converted electric motorcycle is from the battery. The type of battery used is lithium-ion with a capacity of 72 V/20 Ah. The purpose of this research is to increase the efficiency of electrical power consumption required by the driving motor from previous research, where the electrical power consumption of the converted electric motorcycle with a v-belt power transmission at a driving speed of 50 km/h is 724 Watts. It is only able to cover a distance of 99 km. The method used in this research is to test the electrical power consumption of the converted electric motorcycle with a synchronous belt power transfer. The results of the test show that the converted electric motorcycle with a synchronous belt power transfer consumes only 305 Watts of electrical power at a speed of 50 km/h. This means that the efficiency of electrical power consumption increases by 120% compared to the v-belt power transfer, and the driving distance at a speed of 50 km/h is 235 km.

The bicycle manufacturing industry is a sector that continues to experience growth as public awareness of the importance of a healthy, environmentally friendly lifestyle increases, and interest in cycling grows. In the production process, the Welding Division plays a crucial role as it is responsible for assembling the main components of bicycles, namely the frame. This study focuses on demand forecasting in this division so that the company can determine production targets more accurately. The single moving average method was chosen as the forecasting technique because it is suitable for limited data conditions, both for production and sales needs. The researchers divided this method into three variations: forecasting with a 2-month, 3-month, and 4-month period. The analysis results showed that the 2-month single moving average method provided the most accurate results with a mean absolute percentage error of 28%, which is lower than the other methods. Overall, the average production in the Welding Division reached 54,050 units.

This research explores the implementation of Green Human Resource Management (GHRM) practices in sustainable seafood small and medium enterprises (SMEs) operating within seaweed cultivation communities in Serang Regency, Banten. Through qualitative methodology employing embedded case study design, the research involved 38 respondents during March–December 2024, combined with focus group discussions (3 sessions), 120 hours of participatory observation, and analysis of 73 organizational documents. Findings reveal that despite limited formal HRM infrastructure, seaweed farming communities implement emergent GHRM practices rooted in systematic integration of local ecological knowledge and community-based management traditions. The research identifies three primary dimensions of implementation: (1) green environmental management practices encompassing water quality monitoring, waste management, and ecosystem conservation; (2) green human development practices integrated within continuous training and environmental awareness; and (3) green organizational culture embedded in traditional coastal community values and participatory decision-making. Analysis using the Ability-Motivation-Opportunity (AMO) framework demonstrates that GHRM effectiveness depends on alignment between technical environmental capability building, structuring of economic incentives for sustainable behavior, and creation of participatory opportunities in environmental decision-making. The research identifies significant barriers including limited technical and financial capacity, minimal access to green certification training, and gender inequality in employment placement. The research proposes a contextually-adapted GHRM framework for informal SME contexts, emphasizing capacity building with integration of indigenous knowledge systems and coordinated institutional support. The research contributes to understanding GHRM implementation in informal SME contexts within developing economies and demonstrates the relevance of indigenous management approaches in achieving sustainable development objectives.

This study aims to accurately forecast short-term electrical energy demand in a Jabodetabek industrial facility to support sustainable manufacturing and precise utility management. To address the highly dynamic and non-stationary nature of energy consumption, this research applied Holt’s Double Exponential Smoothing method. A 24-month historical dataset, spanning from January 2024 to December 2025, was analyzed to generate a six-month operational projection. Model performance was rigorously evaluated using Mean Absolute Deviation (MAD), Mean Square Error (MSE), and Mean Absolute Percentage Error (MAPE). The forecasting demonstrated outstanding predictive accuracy, yielding a MAPE of 1.26%, a MAD of 20,79, and an MSE of 690.40. The projection indicates a consistent linear escalation, with energy demand expected to reach 2.020,72 MWh by mid-2026.These findings confirm that Holt’s algorithm effectively captures underlying linear trends without seasonal behaviors. Integrating this precise mathematical model into standard procedures provides crucial early warning signals for capacity planning, mitigates utility shortages, and strongly supports the strategic mandate of green operations.
