Greywater Flow Characteristics for Closed Channel Maintenance

Knowing the characteristics of wastewater and its interaction with the channel is crucial to finding a suitable model and maintenance method to solve the closed channel problem. The purpose of this study is to find the relationship and how much it influences the characteristics of wastewater in closed channels and analyze the limit deposit velocity (LDV) of wastewater so that there is no deposition. The parameters used to analyze wastewater characteristics are density, oil and fat, specific gravity, total suspended solids, total dissolved solids, and kinematic viscosity. The parameters used to analyze the flow characteristics in closed channels are velocity, discharge, Reynolds number, friction coefficient, energy loss, and hydraulic gradient. The method used is experimental research by simulating a closed-channel model prototype. The closed channel model is made from an acrylic pipe with a length of 6 m and a pipe diameter of 0.064 m. Simulations on each wastewater sample and the discharge variations used were 0.005, 0.004, 0.003, and 0.0015 m3/s. Velocity measurements at a 0.5 pipe water level height and distances of 0, 2, 4, and 6 m. The results showed that the nature and composition of the wastewater the flow velocity. The large value of wastewater parameters shows that the flow velocity is small. The wastewater content is considered a load that must be transported to the end of the closed channel. When the discharge increases, the velocity will increase, Reynolds number will increase, and the energy loss will be large, while the friction coefficient is inversely proportional to Reynolds number. The velocities of clean water samples are 2.90 - 1.07 m/s, tofu - making is 2.83 - 1.07 m/s, household is 2.74 - 0.85 m/s, laundry is 2.84 - 1.03 m/s, and the workshop is 2.54 - 0.66 m/s. The limit deposit velocity (LDV) for household wastewater is 1.49 m/s to prevent deposition in closed channels. Doi: 10.28991/CEJ-2023-09-01-03 Full Text: PD

Selling Spectacular Urban Life: Urban Space and Lifestyle in the Promotion Media of Apartment in Yogyakarta

This article discusses how urban life is represented through the Barsa City, Uttara the Icon, and The Palace apartment advertisements and promotional videos. Applying Guy Debord's idea of spectacle to examine how urban life is transformed into visualization and commodification, also George Ritzer’s idea of re-enchantment of the disenchanted world and the new means of consumption. This article is aimed to analyze the position of apartments in the urban space of Yogyakarta that is discursively constructed through apartment promotional media. The conclusion of this research shows that apartments are functionalized to create the spectacle of the city. Urban space and life are aestheticized and spectacularized, in which apartments are displayed as part of dramatic and extravagant urban arts. Presented as one-stop-serving buildings, the apartments also promote the fusion of living space, urban style experience, and consumption which lead to the difficulty in distinguishing spatial boundaries. The advertisements and promotional videos of the apartment in Yogyakarta also promote temporal paradox. On the one hand, it promotes time compression and speed, meanwhile, on the other hand it promotes prolonged and extended time to foster consumption in the urban space

The effect of Rhodamine B on the cerebellum and brainstem tissue of Rattus norvegicus

Background: Rhodamine B is a component of xenobiotic substance metabolized by cytochrome P450 in the body to produce free radicals, which affects the activity of Superoxidase Dismutase (SOD), thereby, leading to oxidative stress, injury, increase in cell apoptosis and brainstem. This study aims to determine the effect of Rhodamine B on BAX and BCL-2 in the cerebellum and brainstem tissue of Rattus norvegicus.Design and Methods: The True Experimental Design was used to carry out a post-test examination on the control group of twenty-eight Wistar female Rattus norvegicus mice between the ages of 10-12 weeks. Then, samples were categorized into 4 groups in body weight doses of 4.5 mg/200g, 9 mg/200g, and 18 mg/200g. They were administrated with Rhodamine B personde for 36 days. Results: The results showed that Rhodamine B had a direct and indirect effect on BAX and BCL-2 expressions, respectively, in the cerebellum tissue and wistar strain of Rattus norvegicus. In addition, the positive path coefficient of BAX expression has a positive effect on BCL-2. This means that an increase in BAX has a direct impact on decreasing BCL-2 expression in cerebellum tissue and brainstem of Rattus norvegicus wistar strain along with an increased dose of Rhodamine B. Conclusions: In conclusion, Rhodamine B tends to increase BAX expression which directly decreases BCL-2 in Cerebellum tissue and Brainstem in Rattus norvegicus along with increasing doses

UJI JENIS NUTRISI PADA SELADA HIDROPONIK SISTIM WICK: Nutrition Type Test On Hydroponic Lettuce Wick System

Simple hydroponic wick system (Wicks) can be applied in overcoming the land crisis for the development of horticultural crops.  Nutrients are an important part of hydroponic activities and Abmix is ​​a standard nutrient in hydroponic farming activities.  It is necessary to test the opportunities for the utilization of nutrients from POC and synthetic fertilizers. This study aims to determine the opportunities for using liquid organic fertilizers (POC) and synthetic fertilizers in hydroponic lettuce plants using the wick system.  The treatment consisted of 5 types of nutrition, namely (1) AB mix (control) 50 mL per 10 liters of water (ABM); (2) NPK 10 g + Gandasil 5 g per 10 liters of water (NPG); (3) Abmix 25 mL + 5g NPK + 2.5 g Gandasil per 10 liters of water (ANG); (4) Abmix 25 mL + 400 mL POC from chicken feather waste (ABP) and (5) 5 g NPK + 2.5 g Gandasil + 400 mL POC chicken feathers per 10 liters of water (NGP).  The results showed that there were differences in the growth of lettuce in the hydroponic wick system due to the type of nutrition treatment. Alternative nutrients that have the potential to be used in wick cystic hydroponic lettuce are Abmix 25ml + 5g NPK + 2.5 g Gandasil per 10 liters of water (ANG) and Abmix 25 mL+ 400 mL POC from chicken feather waste per 10 liters of water (ABP

Stomata of Grass in The Ex Tin-Mining Land in Bangka

Tin-mined land experiences drought, high light intensity, and temperature which is less supportive of plant growth. The study observed the anatomical responses of grasses leaves. This study aims to measure stomatal density, stomatal index, guard cell length, and guard cell width of three grass species that grow naturally in ex tin-mined land and in undisturbed land. Description method carried out based on the paradermal incision resulted in the wholemount method. The results showed each grass species has a different response to their different habitats. The stomatal density of Imperata cylindrica and Paspalum conjugatum collected from ex tin-mined land were higher than to those plants collected from undisturbed land, however the stomatal density in Scleria levis showed the opposite result. Stomatal index of all three species increases in ex tin-mined land were higher than in undistributed land. Guard cell lengths of I. cylindrica and P. conjugatum were smaller than those in undistributed land, but Scleria levis showed the opposite result. Guard cell width of I. cylindrica and S. levis were wider than those in undistributed land, but P. conjugatum showed the opposite result. These responses may reflect their adaptiveness to tin soils
