Analisis Nilai Penurunan dan Faktor Keamanan Pada Perbaikan Tanah Dasar Metode Deep Cement Mixing

Konstruksi di Indonesia yang sering dijumpai berada di atas tanah lunak memiliki masalah yaitu penurunan. Kondisi tersebut mengharuskan dilakukannya perbaikan pada tanah lunak tersebut. Banyak metode perbaikan tanah lunak yang bisa dilakukan, salah satunya ialah metode deep cement mixing. Fungsi utama dari penggunaan perbaikan metode ini ialah mengurangi penurunan di bawah timbunan. Ada berbagai macam pola penggunaan deep cement mixing, namun pola yang digunakan dalam penelitian ini ialah pola persegi. Analisis ini dilakukan dengan menggunakan Program Elemen Hingga 2D. Pemodelan deep cement mixing dilakukan dengan berbagai jenis variasi jarak (1,5 m; 2,0 m dan 2,5 m) dan persentase campuran semen (2,5%; 5,0%; 7,5%; 10,0%; 12,5%; 15,0%) yang diberi beban timbunan batubara setinggi 18 meter yang diasumsikan berbentuk beban merata. Pemodelan menggunakan metode elemen hingga 2D tanpa menggunakan perbaikan deep cement mixing menghasilkan nilai penurunan sebesar 3,11 meter dengan waktu konsolidasi 8.787 hari. Hasil pemodelan yang telah dilakukan menggunakan program elemen hingga menunjukkan bahwa perbaikan deep cement mixing dapat mengurangi penurunan dari 17,04% hingga 97,41% serta waktu konsolidasi dari 2,64% hingga 89,64%. Variasi perbaikan deep cement mixing yang paling optimal berada pada variasi jarak 1,5 meter dengan persentase campuran semen 7,5% menghasilkan pengurangan nilai penurunan sebesar 96,90% yaitu 0,10 meter dengan waktu konsolidasi berkurang sebesar 88,82% selama 982 hari serta pada variasi perbaikan dengan jarak 2,0 meter dengan persentase campuran 12,5% menghasilkan pengurangan nilai penurunan sebesar 90,06% yaitu 0,31 meter dengan waktu konsolidasi berkurang 83,97% selama 1408 hari

Long Distance Dual SpO2 Monitoring System for Premature Babies Using Bluetooth Communication

Monitoring the baby's health status is very important, especially for babies born prematurely. Oxygen saturation levels in newborns are very important to know because when the oxygen saturation levels in newborns are low, it is necessary to watch out for hemodynamic abnormalities in the baby. Measurement of oxygen saturation levels in newborns can help detect congenital abnormalities in infants early. This study aims to design an equipment system to continuously monitor the condition of oxygen saturation in newborns. Where in this discussion a monitoring tool is used to monitor 2 premature babies in a baby incubator simultaneously using a Neonatal Fingertip sensor. The system will display the oxygen saturation (SpO2) value and signal. Monitoring on this tool is done wirelessly using the HC-05. Based on the results of tests and measurements in 5 different patients with a pulse oximeter comparison, the difference value of 1% in each patient's results was obtained. The results of this study will greatly help facilitate the work of paramedics in monitoring the vital conditions of newborn babies

Study of Environmental Parameters on Lobster (Panulirus spp.) Enlargement with Fixed Cage at GWD, Banyuwangi

One of the marine commodities, Lobster (Panulirus&nbsp;spp.), has unabated demand in the global market, while, Lobster production remains static due to the difficulty of implementing its rearing activities. Relative rearing of lobster (Panulirus spp.) is usually performed using the floating net cage method with calm water conditions. In contrast, areas with extreme&nbsp;weather&nbsp;conditions tend to have difficulty applying this method. The potential of using the fixed cage method was assessed by rearing the Lobster at Pesona Bahari Banyuwangi Fish Cultivation Group. This research aimed to investigate the feasibility of the environmental conditions in the waters of GWD, Banyuwangi. The study was conducted for three months. Data such as temperature and light intensity through the help of a pendant was collected. Water quality parameters were recorded during this study, including salinity, pH, dissolved oxygen, and current velocity. Sampling was conducted four times to see the relationship between length and weight. The results showed that the GWD environmental parameters were very supportive for lobster rearing, with temperature values ​​ranging from 27.2oC - 30.1oC, DO around 4.6 mg/l - 5.2 mg/l, salinity 28o/oo - 30o/oo, pH 7 - 8.2, the current speed is 0.468 m/s, and the light intensity is 0 lux - 3,616 lux. The growth pattern of all sampling results except sampling 2 (isometric) has a negative allometric result, with length and weight having a solid relationship. The fixed cage method is considered suitable for lobster rearing activities because the environmental parameters follow their natural habitat and the Fulton condition factor (K) value of more than 1. The greater the value of the Fulton condition factor (K), the healthier the condition lobster
