Abstract

The construction of dams is very important for fulfill water demand and as flood control. In addition to having many benefits, a dam also has a high risk. The stability of the dam is strongly influenced by the magnitude of the pore water pressure. The purpose of the study was to determine the response of pore water pressure to the reservoir water level, as well as to find out the comparison of the results of pore water pressure analysis using plaxis 2D and piezometer instrument readings. The piezometer readings are graphed as a function of the reservoir water level. Based on the graph, it can be seen that the piezometer readings correspond to the fluctuations in the reservoir water level. The piezometer upstream side have a faster response to the reservoir water level, which is between 14 to 41 days. While downstream piezometers have a longer response, which is between 25 to 61 days. Pore ​​water pressure analysis using plaxis 2D at location P.17 (upstream) resulted in a smaller value than piezometer reading. While at location P.18 (downstream) it produces a greater value than the piezometer reading. The relative error value of the two analyses is 7.73% < 12% is still considered good, so the difference is acceptable.

Abstract

Enzymes, especially pectinase, plays an important role in the processing of tea that determines the quality and the color appearance of black tea. The main obstacle encountered in the application of enzymes in food processing in general, and in particular in the processing of black tea is the price of commercial enzyme that are still very expen­sive, because it is still imported. Indonesia has a high fungal diversitythat is potential as producer of commercial pectinase enzyme. To reduce the cost of production, fermentation was done using solid waste of plantation that rich of pectin content such as cocoa pod husk that has not been optimally utilized. The research aimed to develop the production technology for pectinase enzymes of fungi through solid substrate fermentation for applications in the processing of CTC black tea. Research includes the isolation and selection of local superior fungi producing enzymes pectinase, optimiza­tion of enzyme production by fungi isolates were selected through a solid substrate fermen­tation using cocoa pod husk waste, production optimization included optimization of fermen­tation time and substrate composition, enzyme extraction of fermented substrate, and appli­cation of pectinase enzyme extracts in the processing of CTC black tea and sensory test of fermented tea. The results showed that it has been obtained isolates of Aspergillus niger on Pectinase Screening Agar Medium (PSAM) which was capable of producing pectinase enzyme on growing media of mix cocoa pod husk and rice bran with additional of enrichment media. The optimum conditions of pectinase production was obtained in the composition of cacao pod husk: rice bran (80:20 w/w) plus enrichment media, the incubation time of 9 days, which produced pectinase activity of 125 U/mL. Applications of pectinase on enzymatic oxidation of CTC tea proved that it was capable of raising the quality of the tea flavor, though the tea gradedid not change.

Abstract

Pemberlakuan Pembatasan Kegiatan Masyarakat (PPKM) Darurat yang ditetapkan oleh pemerintah menimbulkan dampak negatif bagi perekonomian masyarakat Indonesia terutama bagi Usaha Mikro, Kecil, dan Menengah (UMKM). Penurunan pendapatan sangat dirasakan oleh UMKM, salah satunya yang ada di Desa Dukuh Menanggal, Gayungan-Surabaya. Salah satu faktor kurangnya pendapatan UMKM di desa tersebut karena masih belum memanfaatkan pasar digital dengan alasan keterbatasan keterampilan dalam mengakses teknologi. Program pengabdian masyarakat ini bertujuan untuk mendorong optimalisasi media sosial khususnya Instagram sebagai salah satu langkah memanfaatkan pasar digital untuk meningkatkan penjualan terutama dalam kondisi pandemi Covid-19 saat ini. Metode yang digunakan adalah penyuluhan yang diikuti dengan pendampingan yang berfokus pada optimasi penggunaan Instagram Ads sebagai sarana peningkatan penjualan. Output dari penggunaan Instagram Ads sebagai salah satu alternatif bagi UMKM antara lain memperluas pangsa pasar UMKM, meningkatkan brand-awareness produk UMKM, dan secara tidak langsung dapat meningkatkan penjualan.

Abstract

Bendungan Ameroro berlokasi di Sulawesi Tenggara dibangun oleh Kementerian Pekerjaan Umum dan Perumahan Rakyat yang hingga saat masih dalam proses penimbunan. Deformasi bendungan sebenarnya sudah mulai terjadi sejak proses konstruksi bendungan dan kemudian berlanjut pada masa operasional bendungan setelah konstruksi selesai. Oleh karena itu, pengamatan dan analisis deformasi tubuh bendungan sangat penting dilakukan sejak masa konstruksi untuk menghindari terjadinya kegagalan bendungan di kemudian hari. Penelitian ini bertujuan untuk mengidentifikasi perilaku deformasi internal vertikal Bendungan Ameroro berdasarkan data hasil monitoring Multilayer Settlement . Identifikasi dimaksudkan untuk menilai perilaku normal atau abnormal zona inti timbunan bendungan dengan data pembacaan instrumen Multilayer Settlement yang dipasang pada Bendungan Ameroro untuk mengetahui perilaku deformasinya berdasarkan rujukan empiris. Grafik pembacaan hasil monitoring Multilayer Settlement menunjukan bahwa pada plat magnet paling bawah IMS 1-8 sudah mengalami penurunan yang stagnan pada elevasi timbunan +88,50 m sehingga diprediksi pada kenaikan timbunan berikutnya deformasinya akan stabil. Batas normal yang dirujuk adalah ketika ketinggian timbunan kurang dari 50 m total penurunan umumnya berada pada urutan kurang dari 1% sampai dengan 2,5%. Dari hasil analisis, nilai settlement pada inti Bendungan Ameroro yang terjadi masih dalam ambang batas normal.

Abstract

Pomegranate is one of the plants of the Lythraceae family. Pomegranate plants are spread from the subtropics to the tropics, from the lowlands to altitudes below 1000 masl. Pomegranate contains flavonoid compounds that can be used as traditional medicine for hepatoprotectors. The aim of the researcher was to determine the total flavonoid levels in pomegranate juice (Punica granatum L) by UV-Vis Spectrophotometry. The method used in the study is the Chang method. Identification of flavonoids with concentrated HCl reagents and magnesium metal causes a change in color to red which indicates a positive sample containing flavonoids. The results of the study showed total flavonoid levels contained in pomegranate juice 0.0075766% QE. Results Variation Coefficient Value (% KV) of the sample is 0.7475%, Variation Coefficient (% KV) is the percentage ratio between the standard deviation and the average. % KV is used in grading to express precision.
