Abstract

Logam berat seperti timbal (Pb) dan kadmium (Cd) merupakan polutan berbahaya yang dapat mengganggu fungsi fisiologis organisme akuatik, termasuk ikan nila (Oreochromis niloticus). Penelitian ini bertujuan untuk mengetahui respon fisiologis ikan nila terhadap paparan Pb(NO₃)₂ dan CdCl₂ pada konsentrasi 1 ppm selama 3 jam. Parameter yang diamati meliputi kecepatan respirasi, morfometrik saluran pencernaan, serta parameter hematologi seperti jumlah eritrosit, leukosit, dan kadar hemoglobin. Hasil menunjukkan bahwa paparan CdCl₂ memberikan efek toksik lebih kuat dibandingkan Pb(NO₃)₂, dengan penurunan signifikan pada jumlah eritrosit, kadar hemoglobin, dan kecepatan respirasi. Sementara itu, paparan Pb(NO₃)₂ juga menyebabkan penurunan hemoglobin dan eritrosit, serta perubahan warna organ pencernaan seperti empedu dan hati, namun efeknya tidak sebesar CdCl₂. Kedua logam berat meningkatkan jumlah leukosit sebagai respons imun terhadap stres oksidatif. Hasil ini mengindikasikan bahwa logam berat, terutama Cd, dapat mengganggu sistem pernapasan, peredaran darah, dan fungsi pencernaan ikan nila.

Abstract

Moringa plants can be found in most tropical and subtropical climates. In some parts of Indonesia, the plant is called kelor or marungga. People need the tree as a source of protein, vitamins, minerals, and carbohydrates. The plant contains more than 90 nutrients, antioxidants, and 8 essential amino acids, called the ‘elixir tree’. The problem with this plant is that its leaves are easily damaged when picked. One way to avoid this is to perform a drying process. This Moringa dryer consists of an inner cabinet made of aluminum and an outer side made of zinc. The cabinet measures 40 cm long, 35 cm wide, and 35 cm high, has three shelves arranged horizontally, and each shelf can dry between 100 grams to 200 grams of moringa leaves simultaneously. In addition, it has a heater consisting of two 125-watt heaters and two upper and lower fans. In the first experiment, Moringa leaves were dried for 9 hours at 40°C, yielding 30g of dried leaves from 100g of fresh leaves. The second experiment lasted 6 hours at 50 °C, yielding 30 g of dried leaves from 100 g of fresh leaves. Finally, the leaves were dried for 3 hours at 60°C, yielding 30g of dried leaves from the initial 100g. These results also show a large weight loss at various temperatures and durations. After calculating the percentage of weight loss, it was found that the leaves lost 70% of their weight. Outseal PLC can automatically control the drying process according to the pre-programmed program. Temperature and humidity sensors maintain the nutritional quality and texture of the moringa leaves produced by controlling the dryer environment appropriately. This tool can be used easily by users without requiring high technical skills.

Abstract

Natural gas production involving several gas-well streams with different operating pressure creates a problem, especially for lower-pressure streams. Usually, a compressor unit is installed to enable a lower-pressure stream to tie in the higher-pressure stream. However, this solution requires high costs and investment related to compressor operation. Natural gas ejector provides an alternative, where a higher-pressure stream act as the motive fluid to withdraw the lower-pressure stream.  This work aims to simulate the flow inside the ejector using ANSYS Fluent CFD simulator. The model used is validated to published data by other authors. Ejector efficiency is calculated for several operating pressure and ejector geometry: ratio of mixing tube length to diameter. We found that the variation in L/D ratio of mixing tube in current study did not significantly affect the ejector performance. Conversely, it was strongly affected by both motive and suction pressure, where the entrainment ratio is generally higher for lower pressure ratio. On the other hand, the efficiency of ejector process exhibited an optimum behavior, where we obtained the highest efficiency of 26.7% at pressure ratio of 0.1765. Therefore, this result can be utilized as the recommended operating condition.

Abstract

This study aimed to determine the perceptions of pre-service biology teachers and in-service biology teachers on artificial intelligence in Biology learning. AI has recently become a new trend and has changed many aspects of life. Artificial intelligence allows machines to learn from experience, adapt to new inputs, and perform human-like tasks like ChatGPT, launched in Q4 of 2022. The survey method used in this study. We used a questionnaire from 42 respondents of in-service teachers and pre-service teachers, respectively. Selected teachers were senior high school biology teachers who have used the independent curriculum in their schools. This study showed that the pre-service biology teachers (69%) had higher perceptions than in-service biology teachers (40.5%). This result followed by AI usage; 28.6% of pre-service biology teachers and 7.1% of in-service biology teachers used AI daily. However, the pre-service and in-service biology teachers believed that AI could be implemented in the new curriculum to increase student achievement on biology subject. This study concluded that the perceptions of to use AI is still low. So, AI must be introduced to the pre-service and in-service biology teachers.

Abstract

This activity aims to increase understanding and assist MSME players in Pleret Panjatan Kulon Progo in obtaining halal certification for their products through counseling and mentoring. This research uses the community service method which was carried out in the Pleret Panjatan Kalurahan Office Hall on September 19, 2024. The activity consists of three stages: planning, counseling, and mentoring. Resource persons from the Ministry of Religious Affairs of Bantul Regency provided material on halal certification and the application process through the SiHalal portal. Assistance is carried out directly to assist MSME players in the process of applying for halal certificates and fulfilling administrative requirements. This activity succeeded in increasing the understanding of culinary MSME players regarding halal certification, as well as motivating them to register their products through the SiHalal portal. In addition, the assistance helps MSME players in fulfilling administrative requirements, such as making a Business Identification Number (NIB), so that they can obtain a halal certificate. The limitation of this research lies in the relatively short implementation time, so that it has not been able to reach all MSME players in Pleret Panjatan Kalurahan as a whole. In addition, limitations in the initial data collection made some potential MSME actors not yet involved in this activity. This activity contributes to increasing the understanding and awareness of MSME actors in coastal areas regarding the importance of halal certification. This activity also makes a practical contribution to the halal certification process through the Free Halal Certificate (Sehati).
