Abstract

Hasil simulasi WaterNet jaringan eksisting dengan aliran berubah diketahui bahwa kinerja sistem jaringan tidak optimal yaitu masih terdapat aliran laminer pada pipa sebanyak 26 pipa dan sisa tekanan pada simpul pelayanan rendah yaitu 9,88 mH2O, seperti pada lokasi desa Sirapan, Kemangsen dan Jagalan. Optimalisasi jaringan eksisting dilakukan dengan metode memperbesar pipa yang berdiameter kecil dari node sub Jagalan ke node pelanggan, dan membangun tangki baru serta menaikkan elevasi tangki pada daerah pelayanan Perumtas III dimana pompa 2(dua) beroperasi. Pompa 2 yang beroperasi pada daerah pelayanan Perumtas III diatur debit dan headnya sesuai dengan daya tampung tangki baru. Setelah diadakan optimalisasi hasilnya lebih baik apabila dibandingkan dengan kondisi eksisting karena adanya penghematan operasional pompa rata-rata selama 14 jam dibanding dengan kondisi eksisting waktu operasional pompa 24 jam. Tekanan sisa pada node setelah optimalisasi menjadi lebih baik karena terjadi peningkatan tekanan di semua node meskipun sedikit yaitu 11.53 mH2O.

Abstract

This study aims toexplore the reduction of Anabaena sp. populations using Caesalpinia sappan extract, aiming to determine the optimal concentration to induce oxidative stress that weakens cell structures via increased production of Reactive Oxygen Species (ROS). Water quality parameterssuch as color, turbidity, and Total Dissolved Solids (TDS)were analyzed to evaluate the extract's effectiveness on the aquatic ecosystem. Employing a combination of the TRIZ (Theory of Inventive Problem Solving) method and a True Experimental design, the study optimized extract concentration variations and examined the ability of Caesalpinia sappan (sappan wood) to penetrate the peptidoglycan layer of Anabaena sp. Results obtained over two days indicate that the bioactive compounds in Caesalpinia sappan induce ROS, as evidenced by an increase in color intensity from day 1 to day 2 due to pigment release from Anabaena sp. in response to oxidative stress. Higher extract concentrations led to a significant reduction in Anabaena sp. populations, with the 100% concentration yielding an 86% decrease on day 2, alongside a color reading of 1209 Cu, turbidity of 39.6 NTU, and TDS of 114.5 mg/l. Microscopic observations revealed notable cell disintegration and damage in Anabaena sp. This study confirms that bioactive compounds, such as brazilin and flavonoids in Caesalpinia sappan, contribute to ROS generation, leading to cell death in Anabaena sp. via oxidative stress.

Abstract

Pengabdian ini bertujuan meningkatkan pengetahuan dan manfaat ramuan herbal sebagai pengobatan alternatif, memberikan contoh tentang manfaat ramuan herbal, dan mendorong masyarakat untuk mengintegrasikan pengobatan herbal dalam kehidupan sehari-hari. Ramuan Sapujagat Praktis (temu mangga, lengkuas, kencur, bunga lawang, serai, pulosari, kapulogo, bawang merah) dan Badarmomolo Praktis (temu mangga, lengkuas, bunga lawang, pulosari, kapulogo, daun sembung, adas manis, biji kemukus) yang diproduksi PT Sankara Sehat Sejahtera Badung dikemas dalam bentuk ramuan celup agar lebih praktis, higienis, dan mudah dikonsumsi secara rutin. Pelatihan diikuti 40 ibu-ibu PKK; sebelum dan setelah penyampaian materi, peserta diminta mengisi kuisioner evaluasi dengan lima pertanyaan utama terkait peningkatan pengetahuan, pemahaman manfaat, kepercayaan terhadap pengobatan herbal, serta persepsi tentang efek preventif jamu. Hasil dianalisis secara deskriptif. Peningkatan prosentase evaluasi terhadap lima pertanyaan utama berkisar 8–43%. Persepsi positif peserta terhadap konsumsi rutin ramuan Sapujagat Praktis dan Badarmolo Praktis menunjukkan potensi pemanfaatan ramuan ini dalam upaya promotif dan preventif kesehatan masyarakat, terutama dalam penguatan imunitas, pengendalian gula darah, serta dukungan fungsi hati dan ginjal. Pelatihan ini berhasil memberikan informasi berbasis bukti yang mendalam mengenai manfaat ramuan herbal, yang diharapkan dapat meningkatkan kesadaran masyarakat tentang penggunaan obat tradisional yang aman dan efektif dalam menjaga kesehatan.

Abstract

The Sustainable Development Goals (SDGs) program is a world development agenda that aims to optimize the potential of human welfare resources globally. One such program is sustainable development in the form of green open spaces. The basis for Green Open Space (RTH) regulations is Law Number 26 of 2007 on Spatial Planning and Regulation of the Minister of Public Works Number 5 of 2008. The minimum requirement for green open space in a city is 30% of the total area. The City of Yogyakarta has increased the area of ​​green open space to prevent shrinkage of the area due to the impact of development into a commercial area and as an anticipation of disaster. This study selected the best green open space development areas in the city of Yogyakarta using the AHP and TOPSIS methods. The decision-making analysis method used in this study is AHP-TOPSIS. The results of the analysis stated that the total green open space of Yogyakarta City was 23.7% of the total area with 8.2% public green open space and 15.5% private green open space. By considering the 3 criteria and 10 sub-criteria for the 4 alternatives, it is known that the assessment of technical criteria is considered more important than economic and environmental. While the results of the comparison of the sub-criteria stated that the area is more considered with a weight of 0.187 compared to the other sub-criteria. The largest alternative preference value is the Umbulharjo Kemantren at 0.638, the Kotagede Kemantren with a preference value of 0.587. Kemantren Gondokusuman with a preference value of 0.487. As well as Kemantren Danurajen with a preference value of 0.347. Based on the 4 alternatives offered, the Umbulharjo Kemantren was selected and deserves to be recommended as an area for the Yogyakarta City Green Open Space development.

Abstract

In this paper, we report research on the extraction of natural dyes from yellow and orange marigold (Tagetes erecta L.) petals using different solvents. This research aims to determine the optimal dye removal process, investigate stability, and establish color intensity profiles. In order to extract natural dyes that produced various shades of the dried powder of yellow and orange marigold flower petals, two solvents with different polarities, n-hexane and ethyl acetate were used. The maceration procedure using different solvent types was carried out separately. The stability study revealed that all the dyes at room temperature showed better stability with minor changes observed by UV-Visible (UV-Vis) spectrum profiles, indicating that the extracts were stable until the 30th day. To ascertain the color intensity profiles, analytical tests such as UV-Vis spectroscopy and colorimetry utilizing a color reader device were carried out. The color intensity profile of the yellow and orange marigold flower extracts resulting from the UV-Vis spectrum analysis showed that the absorption of the ethyl acetate extract is higher. The pigment concentration, which is also expressed by absorbance, is connected to variations in color intensity. Additionally, the color intensity profile characterization using a color reader revealed that the n-hexane and ethyl acetate extracts had different Commission Internationale d'Eclairage (CIE) L*, a*, and b* values. The yield and color intensity of the extracts were affected by the solvent polarity. In conclusion, the study of the extract's color intensity profile using UV-Vis spectroscopy and a color reader shows that the intensity parameters are aligned.
