Abstract

Pada perencanaan jaringan Kagan-Rodda berdasarkan data curah hujan rata-rata harian maksimum daerah dari metode Rata-rata hitung untuk tingkat kesalahan perataan (Z1) 5% didapatkan 4 buah stasiun hujan terpilih dari 8 buah stasiun hujan pada kondisi eksisting. Sedangkan pada perencanaan jaringan Kagan-Rodda berdasarkan data curah hujan rata-rata harian maksimum daerah dari metode Poligon Thiessen untuk tingkat kesalahan perataan (Z1) 5% didapatkan 4 buah stasiun hujan terpilih dari 8 stasiun hujan pada kondisi eksisting. Metode Rata-rata hitung mengahasilkan kesalahan relatif untuk setiap kala ulang tertentu adalah lebih kecil dari 5%, yaitu 1.12% - 4.49% . Dengan besarnya curah hujan rancangan tersebut dapat dihitung besarnya debit banjir rancangan dengan metode HSS Snyder sehingga diperoleh banjir rancangan yang terjadi antara 1009.00 m3 – 2001.60 m3 untuk setiap kala ulang tertentu. Sedangkan metode Poligon Thiessen menghasilkan kesalahan relatif untuk setiap kala ulang tertentu lebih kecil dari 5% yaitu antara 1.42% -4.68%. Sehingga dengan curah hujan rancangan tersebut pula dapat dihitung besarnya debit banjir rancangan dengan metode HSS Snyder sebesar 911.14 m3 –1806.90 m3 untuk setiap kala ulang tertentu. Dengan demikian dapat disimpulkan bahwa untuk perencanaan jaringan Kagan Rodda di daerah studi, kedua metode ini bisa digunakan. Meskipun metode Rata-rata hitung memberikan hasil yang lebih baik daripada metode Poligon Thiessen, yaitu terlihat dari rata-rata besarnya kesalahan relatif yang terjadi. Besarnya kesalahan relatif untuk metode Rata-rata hitung adalah sebesar 3.0%, sedangkan kesalahan relatif untuk metode Poligon Thiessen adalah sebesar 3.6%.Kata Kunci: Analisa Metode Eksisting, Analisa Metode Kagan-Rodda, PolaPenyebaran Stasiun Hujan.

Abstract

This study aims to analyze the effect of different cross-sectional areas of recirculation systems on water quality in tilapia (Oreochromis niloticus) rearing. The method used is an experimental method with a completely randomized design (CRD), 4 treatments and 3 replications each. The treatments are P0 (conventional), P1 (2 cross-sectional units with an area of 1,087 cm2), P2 (4 section units with an area of 2,174 cm2), P3 (6 section units with an area of 3,261 cm2). Each treatment used the same filter, namely cotton, zeolite, pumice stone, and bio balls. The results of the research the highest absolute weight growth was obtained in the P3 treatment with an average value of 4.56 g and followed respectively P2 4.38 g, P2 3.03, P0 2.59 g. The highest absolute length growth rate was obtained in treatment P3 2.71 cm, P2 of 2.54 cm, P1 of 1.87 cm, and the lowest absolute length was found in treatment P0 of 1.62 cm. The highest feed conversion value was at P0 at 3.91, followed by P1 at 2.84, P2 at 2.06, and the lowest at P3 at 1.94. The highest survival value was P3 of 85.00, P2 r 83.33, P1 73.33 and the lowest was P0 of 55.00. The highest diversity coefficient value was obtained in treatment P0 of 17.58, followed respectively by treatment P1 of 16.05, P2 of 12.91 and the lowest coefficient of diversity found in treatment P3 of 12.69. The conclusion of this study is the use of different recirculation cross-sectional areas has a significant effect on absolute weight growth, absolute length growth, feed conversion ratio, survival, and water quality. The recirculation cross-sectional area in P3 treatment with a cross-sectional area of 3.261 cm2 gave good results for the survival of tilapia (O. niloticus).

Abstract

the Indonesian people and the world in general. This problem has triggered exploration of alternative materials that can be used as substitute fuels for fuel oil. Corn cobs are one of the alternative ingredients that can be converted into liquid fuels. Corn cobs which are hydrolyzed to produce glucose are then fermented to produce ethanol. This research carried out the hydrolysis step against corncob to become glucose so that it can be fermented into liquid fuel in the form of ethanol in the next stage. Hydrolysis is carried out using sulfuric acid. The results showed that from as much as 10 grams of dried corn cobs were crushed then oven for 4 hours at a temperature of 60oC then added 100 mL of sulfuric acid solution in various normalities. Hydrolysis is run at a temperature of 100 Oc, the results of hydrolysis are analyzed at various time variations. The results of the trial showed hydrolysis using sulfuric acid with a variation of time can convert corncob into glucose ± 54 mL.

Abstract

Cryptocurrency is a form of digital currency that uses cryptographic technology for security and operates independently without a central bank. Cryptocurrencies offer several benefits compared to traditional currencies, including decentralization, security, anonymity, and accessibility. However, cryptocurrencies also carry some risks, including volatility, security, and regulation. This research aims to educate students about cryptocurrency and how they can get involved with cryptocurrency. The research method used is literature review, using library materials as the main source, meaning that the data is collected from the literature, whether in the form of journals, online media, books and others. Which is still related to cryptocurrency. The research results show that students can engage with cryptocurrencies by purchasing them, mining them, or accepting them as payment. However, students should also understand the risks associated with cryptocurrencies and do research before getting involved in cryptocurrency investments..

Abstract

The high growth of developed land in the Banyumanik Sub-District, especially in residential and commercial areas, occurred due to the high demand for housing, lifestyle fulfillment, and speculation and investment by the upper-middle-class society. The reduction or loss of land with vegetation cover in the Banyumanik Sub-District increases the potential for flooding due to more significant surface runoff than water absorption during heavy rainfall. This research used integrated spatial analysis to generate information on the critical level of water infiltration in the research area using the Analytical Hierarchy Process (AHP) method. Both primary and secondary data collected will be compiled and subjected to spatial analysis to address the issues at hand. The weight of each parameter class produced by the AHP method is used for modeling and includes infiltration rate, land use, slope, and lithology parameters. The criticality level of the water infiltration zone in the southern part of Banyumanik Sub-District indicates that the water infiltration condition in the research area consists of good class at 13.589%, naturally normal at 18.405%, started to be critical at 16.114%, slightly critical at 20.764%, critical at 18.286%, and very critical at 12.841%. Changes in land use in the research area have become the primary factors causing alterations in the water infiltration conditions. Infiltration wells are one of the solutions to mitigate runoff as part of sustainable rainwater management. The government plays a crucial role as a policymaker in making decisions to address issues related to urban area development towards sustainable development.

Abstract

A peel-off gel mask is a cosmetic used for facial skin care in the form of a gel. Porang tuber extract peel-off gel mask (Amorphophallus muelleri) contains polyphenolic tannins which are efficacious as antioxidants. This study aims to determine the formulation of peel-off gel mask preparations of porang tuber extract and to determine the physical evaluation and antioxidant test of peel-off gel mask preparations of porang tuber extract using the DPPH method. Experimental formulation method with 7% polyvinyl alcohol (PVA) base. The active ingredient used is porang tuber extract with a concentration of 0.5% (F1), 1% (F2), and 1.5% (F3). Evaluation of the preparations carried out were organoleptic test, homogeneity test, pH test, drying preparation test, spreadability test, hedonic test and stability test. Based on the results of the stability test, it was shown that the peel-off gel mask preparation of porang tuber ethanol extract at various concentrations met the requirements for each test parameter. The antioxidant test results showed that F1 had an IC50 value of 48.75 ppm, F2 had an IC50 value of 43.18 ppm, and F3 had an IC50 value of 11.15 ppm which means that the three formulas have very strong antioxidant activity.
