Abstract

HighlightsThe results of the model and observation showed the similarity of the amplitude and phase formedAt the highest tide was in the position above the Sea Mean level and the current velocity was lower than when heading to the tideThere was a difference in the direction of the current when heading towards high tideStratification of the water column in both seasons tended to be classified in well-mixed watersAbstractBalikpapan Bay is significant as a link between the cities within and outside of East Kalimantan by becoming the primary path used for local transportation and distribution of produced goods. The various anthropogenic activities increased liquid wastes and debris, which flowed through channels and rivers along the bay. This study aimed to determine tidal current patterns in Balikpapan Bay and its influence on salinity and temperature distributions. This study applied a baroclinic three-dimensional (3D) hydrodynamic model, employing wind, tides, and density variations, resulting from the differences of temperature and salinity, as the model input. To simulate the tidal current flow, we applied MOHID Water Modeling System, which the tidal current patterns depicted current directions and speeds at the different tidal conditions. During the displacement toward the high tidal condition, the water mass moves northwestward entering the river body, while at the displacement toward the low tidal condition, the water mass moves southeastward, which flows toward the coast and without the bay. The current speed varies at certain tidal conditions. At the highest tidal condition, the surface elevation ranged 1.3 - 1.5 m above mean sea level; the current rate is lower compared to the displacement toward high tidal condition, which ranged from 0.01 - 0.15 m/s. At the lowest tidal condition, the surface elevation reached 1 - 1.2 m below mean sea level, and the weaker flow velocity took place (less than 0.15 m/s). The results also showed that the water mass temperature tends to be higher in the inner part of Balikpapan Bay, the Balikpapan Bay waters profile that is increasingly shallow towards the bay head also causes this area to tend to have a higher temperature. Also, areas located on the inside of the bay tend to get more freshwater input from rivers, so this area has lower salinity while the area located at the mouth of the bay tends to be of higher salinity because it gets a lot of mass input of seawater from the Makassar Strait.

Abstract

Monitoring electrical energy in the residential sector is necessary because the current use of electrical energy is less effective and is used very excessively and consumes more electrical power. So far, electrical power usage can only be seen through a kWh meter and only shows the cumulative amount of electrical energy used. However, the design limitations of analog panels only display aggregate consumption data, not real-time consumption data and allow direct monitoring in the field as well as manual recording, so more power is required and the process takes a long time. This research aims to design a real-time measurement system that is capable of monitoring electrical energy parameters for buildings in the residential sector for solar cell-based plants, so that consumers can monitor electricity consumption in real time via the internet. The research methodology is an experiment carried out using the monitoring system design method. Through a research scheme, collaboration with industry is proposed for 1 year with the first stage being hardware design, second being software programming. Hardware and software are connected so that the information presented can be accessed directly at that time. This device is designed to replace manual and conventional electrical energy measurement systems. The research results that will be obtained are a design for a real-time electrical power consumption monitoring system in the housing sector. The output is information on electrical energy consumption through off-line and on-line application media which is displayed on a desktop application on a computer, where the data delivery system is via communication

Abstract

Sistem pemantauan Komatsu Machine Tracking System atau Komtrax, menggunakan teknologi komunikasi seluler dan berbasis internet yang canggih. Komtrax sebagai sistem pemantau pada unit alat berat Komatsu seperti HD785-7 dinilai penting sebab kendala-kendala yang muncul pada sistem ini, seperti hilangnya transmisi sinyal akan berdampak negatif pada keseluruhan sistem pembacaan dan monitoring unit. Namun, belum banyak dilakukan penelitian terkait komtrax lost transmit pada unit alat berat. Maka, tujuan utama penelitian ini adalah untuk mengetahui penyebab Komtrax lost transmit pada unit HD 785-7. Penelitian ini berfokus pada analisis penyebab masalah komtrax yang mengalami kehilangan sinyal transmisi, dengan menggunakan metode 8 langkah troubleshooting. Data dikumpulkan melalui pemeriksaan visual dan pengukuran yang didokumentasikan. Hasil penelitian menunjukkan, kerusakan terjadi ketika sambungan antenna dengan ujung pangkal kabel terputus. Sambungan yang tidak kuat serta desain kabel yang bersudut juga berpotensi menyebabkan tarikan saat terjadi getaran selama unit beroperasi. Selain itu, baut pengunci yang kendor juga dapat menyebabkan antenna rentan hilang dari unit. Dari temuan tersebut disarankan untuk selalu melakukan prosedur kawashima yang tepat pada wiring system.
