ANALISA PERBANDINGAN DAYA DUKUNG DAN PENURUNAN FONDASI MINI PILE DENGAN BORED PILE PADA GEDUNG FAKULTAS FARMASI UNIVERSITAS WAHID HASYIM SEMARANG
No full textFarmasi ialah ilmu yang mempelajari asal usul tentang obat. Sehingga, Universitas Wahid Hasyim Semarang melakukan pembangunan Gedung Farmasi untuk meningkatkan sarana dan prasarana kampus. Perencanaan fondasi harus dilakukan dengan mengkaji jenis pondasi yang cocok digunakan. Sebab itu, penelitian ini membahas perbandingan daya dukung dan penurunan antara fondasi mini pile dengan bored pile.
Data tanah memakai data booring (SPT) dari pembangunan Gedung Fakultas Farmasi Universitas Wahid Hasyim Semarang yang terdiri 4 lantai. Metode perhitungan daya dukung memakai metode Meyerhof (1976) dan Reese & Wright (1977). Sedangkan, perhitungan penurunan memakai metode Vesic (1977), software AllPile V6.5E dan Plaxis V8.6.
Berdasarkan analisa pembebanan software ETABS V20 didapatkan beban maksimal 2407,965 kN. Sehingga, direncanakan fondasi mini pile dimensi 25x25 cm dan bored pile diameter 30 cm masing-masing kedalaman 18 m. Hasil kapasitas daya dukung tiang tunggal kedalaman 18 m dengan N-SPTrata-rata 43 fondasi mini pile sebesar 1199,700 kN dan fondasi bored pile sebesar 1141,598 kN. Hasil kapasitas daya dukung tiang kelompok kedalaman 18 m dengan N-SPTrata-rata 43 serta jumlah tiang 3 fondasi mini pile sebesar 2691,889 kN dan fondasi bored pile sebesar 2643,941 kN. Hasil penurunan tiang tunggal kedalaman 18 m fondasi mini pile secara manual sebesar 0,024 m dan software AllPile V6.5E sebesar 0,026 m. Sedangkan, fondasi bored pile secara manual sebesar 0,028 m dan software AllPile V6.5E sebesar 0,027 m. Hasil penurunan tiang kelompok kedalaman 18 m fondasi mini pile secara manual sebesar 0,056 m dan software Plaxis V8.6 sebesar 0,054 m. Sedangkan, fondasi bored pile secara manual sebesar 0,058 m dan software Plaxis V8.6 sebesar 0,055 m. Hasil analisa perbandingan daya dukung dan penurunan fondasi dengan metode manual dan program memiliki selisih yang tidak terlalu jauh antara fondasi mini pile dengan bored pile, namun fondasi mini pile memiliki efisiensi lebih dari fondasi bored pile dari daya dukung dan penurunannya.

Comparison of Double and Triple Exponential Smoothing Methods for Rainfall Prediction
No full textRainfall is water that falls to the ground surface over a certain period and is measured in millimeters (mm). Rainfall is essential for the life of living things. Forecasting plays a significant role in decision-making in modern times, with two main methods: causal models and time series. Time series models have five types of data patterns: random, constant, seasonal, cyclical, and trend. For rainfall forecasting, the Double Exponential Smoothing and Triple Exponential Smoothing methods are used for trend pattern data. This research compares the two approaches based on error values using average rainfall data in Bojonegoro. The results show that Double Exponential Smoothing has a Mean Absolute Percentage Error (MAPE) of 0.6996%, while Triple Exponential Smoothing has a MAPE of 119.1497%. So, Double Exponential Smoothing is more accurate
Multitemporal water quality analysis of a karst spring affected by allogenic recharge
No full textThis research aimed to study the multitemporal water quality of a karst spring affected by allogenic recharge. Allogenic refers to water from adjacent non-karstic regions that replenish karst groundwater through ponors. Research samples were collected for a year at Gremeng Resurgence, the outlet of Gremeng Karst Drainage Basin. The water quality analysis compared the laboratory test outcomes and measurements with existing drinking water quality standards and included hydrogeochemical studies using both trilinear and rectangular Piper plots. The analysis results indicate that rainwater causes dilution; hence, parameter values are relatively low in the rainy season but high in the dry season. Despite this variation, the groundwater at the Gremeng Resurgence meets the quality standards throughout the year. The Piper diagram analysis classifies it as unpolluted, calcium-enriched, average bicarbonate, and bicarbonate groundwater, supporting the finding. © 2023 Author(s)
Service Transformation as a Tool for Promoting Sustainable Rural Development in Central Java
No full textThe current developments in Information Technology (IT) should not only be utilized by the public and the private sectors but also by all parties effectively. The government must also be able to take advantage of these advances in many ways, such as in providing government services. The role of IT in managing government has now become an essential part of the society. This study examines the people\u27s expectations in Melikan Village and focuses on using IT advances to create an independent village. The author then draws upon SDG theories to delineate the service transformation process. It is a qualitative study consisting of primary and secondary data. The data collection techniques used in this study include in-depth interviews, FGD, observations, and document analysis. The findings show that IT has become a vital need for the people in Melikan, but the village government fails to meet those expectations. The study suggests that the local government needs technological innovation to develop Melikan Village and add more personnel to help with government services
HUMAN RESOURCES MANAGEMENT FACETS: ROLE OF ORGANIZATIONAL COMMITMENT
No full textThe prime objective of the current study is to explore the nexus between job involvement, turnover, and organizational
commitment. Meanwhile, the study has examined the mediating role of organizational commitment in the relationship between job involvement and turnover. The study broached an argument that in the era of globalization, it has been regarded to be a key issue to deal with employee turnover for any business organization. To date, agreement on how to practice this concept has not yet been resolved.
Employing the survey-based methodology, the SEM-PLS technique is used to test the hypothesized relationships. So, the current study
has used SEM-PLS as a statistical tool to answer the research questions raised in this study and research objectives envisaged in the
current study. The data is collected from the managers of the manufacturing firms in Indonesia. The findings of the study have provided
support to the theoretical foundation and the proposed hypothesis of the current study. The current study will be helpful for policymakers
and practitioners in understanding the issues related to job involvement, turnover, and organizational commitment. In author knowledge,
this is among very few pioneering studies on this issu
