Abstract

Teknologi penangkapan karbon dengan mikroalga (CCS Mikroalga) merupakan salah satu teknologi mitigasi yang memiliki potensi digunakan dalam upaya penurunan emisi GRK. Teknologi CCS mikroalga bekerja dengan cara menangkap karbon yang dihasilkan dari suatu proses industri kemudian disimpan dan dimanfaatkan untuk proses produksi lain.Teknologi CCS mikroalga terdiri dari dua jenis yaitu fotobioreaktor dan kolam terbuka (open pond). Tulisan ini membahas sejauh mana kontribusi teknologi CCS menggunakan mikroalga dalam upaya penurunan emisi karbon, prospek aplikasinya di masa depan dan kendala dalam aplikasinya. Dalam tulisan ini dijelaskan tentang konsep dan jenis-jenis teknologi CCS menggunakan mikroalga, potensi serapan karbon dari masing-masing teknologi, dan kendala dalam aplikasinya, dan beberapa alternatif untuk meningkatkan peran teknologi ini pada tataran nasional. kata kunci : penangkapan karbon, mikroalga, fotobioreaktor, kolam kultur, serapan CO2.

Abstract

Garam industri sangat dibutuhkan sebagai bahan baku di indutri farmasi, kimia, tekstil, makanan, danla in-lain. Berdasarkan data tahun 2019, Indonesia masih mengimpor garam industri sebesar 2 juta ton per tahun. Sentra produksi garam di Indonesia yang sebagian besar merupakan garam rakyat dengan kadar NaCl di bawah standar kebutuhan industri. Oleh karenanya, diperlukan sebuah pengembangan produksi garam industri dari garam rakyat dengan kualitas akhir yang memenuhi standar kebutuhan industri. Terdapat berbagai teknologi untuk mendapatkan garam industri dari garam rakyat diantaranya adalah dengan pemurnian menggunakan air tua yaitu larutan garam murni jenuh yang akan mengikat pengotor dalam kristal garam sehingga akan didapatkan garam dengan kemurnian tinggi yang memenuhi Standar Nasional Indonesia (SNI). Dalam pelaksanaannya, proses produksi garam industri tersebut akan berpotensi menyebabkan perubahan suatu lingkungan di sekitarnya sehingga perlu dilakukan sebuah studi untuk menganalisis dampak lingkungan yang mungkin ditimbulkan dari proses produksi tersebut. Paper ini akan menjelaskan hal-hal yang berpotensi menimbulkan dampak terhadap lingkungan dari sebuah proses pemurnian garam rakyat menjadi garam industri. Analisis mencakup potensi dampak lingkungan yang ditimbulkan oleh limbah dan produk samping yang berupa padatan, cairan, dan gas.

Abstract

Identifying sources of renewable energy is extremely important. The potential of Tetraselmis sp. in biodiesel production was investigated using a completely randomized design with four treatments. Tetraselmis sp. was cultured on media containing different concentrations of nitrate there are 2 mM and 15 Mm and s 25 ‰ and 35 ‰ salinity. The treatments namely are (N2S25), (N2S35), N15S25) and (N15S35). Analysis of the fatty acid content using gas chromatography-mass spectrometry (GC-MS). The results showed that the highest growth occurred in culture that contained 15 mM of nitrate and 35 ‰ salinity. The lowest growth occurred in culture containing 2 mM of nitrate and 25‰ of salinity. The highest lipid content was found in cultures containing 2 mM of nitrate and 25‰ salinity, it is 34.83%. Seven fatty acids were detected in culture containing 2 mM of nitrate and 25‰ salinity namely myristic acid (4.02%), palmitic acid (40.59%), palmitoleic acid (29.06%), stearic acid (0.95%), oleic acid (12.52%), gamma-linolenic acid (2.56%), and arachidonic acid (9.38%). Four fatty acids palmitoleic acid (8.99%), palmitic acid (37.34%), oleic acid(44.89%), and stearic acid (8.78%) were detected in 2 mM of nitrate with 35‰ salinity. The fatty acids have potential to be used as raw material for biodiesel production.

Abstract

PKK empowerment program in Pambang Pesisir Village through training in the production of fish floss and nuggets. Using an interactive approach, 15 PKK women participated in a 3-hour hands-on demonstration. Activities included visual counseling (30 minutes), a Q&A session (15 minutes), a product-making demonstration (90 minutes), and independent practice (45 minutes). The results showed a significant increase in participants’ understanding and skills, measured through pre- and post-training questionnaires. The participant satisfaction rate reached 95%, with 80% of them interested in developing businesses based on the products learned. The program successfully introduced high-value fish processing alternatives, opening opportunities for income diversification in coastal communities.The training increased participants' awareness of the potential of local marine resources. Further analysis showed a 40% improvement in participants' knowledge of the nutritional value of processed fish products. Additionally, 70% of participants reported increased confidence in their entrepreneurial abilities. The program also strengthened collaboration among PKK members, with 60% expressing interest in forming joint business groups. The potential economic impact is estimated to increase household income by up to 25% in the medium term. Recommendations for program sustainability include establishing production cooperatives, advanced training in small business management, and developing local marketing networks.

Abstract

Kegiatan Pengabdian kepada Masyarakat ini bertujuan untuk meningkatkan literasi hukum dan kesehatan masyarakat di wilayah Kartasura, terutama dalam menghadapi tantangan ketimpangan akses dan rendahnya kesadaran terhadap hak-hak kesehatan. Melalui kolaborasi antara Universitas Duta Bangsa Surakarta dan Universitas Veteran Bangun Nusantara, program ini melibatkan penyuluhan hukum dan sosialisasi kesehatan kepada warga dengan pendekatan partisipatif dan edukatif. Sebanyak 50 peserta hadir dan berinteraksi langsung dengan dua narasumber ahli. Hasil kegiatan menunjukkan bahwa 70% peserta mengalami peningkatan pemahaman mengenai prosedur hukum dan hak kesehatan dasar, serta mulai tergerak untuk membentuk forum advokasi lokal. Perubahan sosial positif ini ditandai dengan munculnya inisiatif pelaporan pelanggaran hak kesehatan secara mandiri dan tumbuhnya kesadaran hukum kolektif. Temuan ini menunjukkan pentingnya integrasi antara aspek hukum dan kesehatan dalam pemberdayaan masyarakat. Diperlukan tindak lanjut berupa pendampingan reguler dan perluasan program ke wilayah lain untuk menciptakan keberlanjutan.

Abstract

This study discusses the development of a decision support system for selecting superior chili seeds using the Simple Additive Weighting (SAW) method. The main problem addressed is the difficulty in objectively determining the best seeds based on multiple criteria. An iterative development model was employed, allowing the system to be gradually improved. Black-box testing showed 100% compliance with the intended functionalities, while user testing using the User Acceptance Test (UAT) method achieved 85% in the “strongly agree” category, indicating that the system is easy to use and relevant to the problems faced by farmers in Koya Barat Subdistrict, Jayapura City, Papua. The analysis results recommend the Mellyana chili variety as the best seed choice. These findings demonstrate that this method effectively supports farmers’ decision-making in selecting superior chili seeds.
