Abstract

Kualitas kelulusan pendidikan tinggi yang masih belum memenuhi harapan dan standar kompetensi kerja, dampak globalisasi yang akan menciptakan persaingan ketat perlu disikapi dengan mempersiapkan kualitas kelulusan pendidikan tinggi yang mampu bersaing. Pertumbuhan pemenuhan tenaga kerja yang terlibat dibidang jasa konstruksi terus meningkat seiring dengan tumbuhnya sektor konstruksi di Indonesia, untuk memenuhi hal tersebut maka dibutuhkan lulusan pendidikan tinggi yang memiliki kompetensi ini. Dengan diterbitkan Peraturan Presiden Republik Nomor 8 Tahun 2012 tentang Kerangka Kualifikasi Nasional Indonesia (Perpres 8/2012 tentang KKNI) dan ditetapkan Peraturan Menteri Pendidikan dan Kebudayaan Republik Indonesia Nomor 49 Tahun 2014 Tentang Standar Nasional Pendidikan Tinggi (Permendikbud 49/2014 tentang SN Dikti), maka perlu ada pemahaman yang memadai dan arah yang benar untuk menerapkan kebijakan tersebut. Dengan rencana diterapkannya peraturan baru maka muncul pertanyaan mendasar yaitu, apakah model sistem manajemen yang berbeda-beda di masing-masing Perguruan Tinggi dapat mempengaruhi capaian pemenuhan (target dan waktu) standar mutu minimal, Hal ini memerlukan evaluasi internal oleh Perguruan Tinggi itu sendiri dan juga evaluasi eksternal oleh kementerian. Adanya persyaratan untuk tenaga ahli konstruksi harus memiliki pengalaman antara 2 sampai dengan 4 tahun dari tahun kelulusan, hal ini akan mengurangi kesempatan kerja bagi lulusan Perguruan Tinggi dan secara tidak langsung belum mengakui kualitas dari lulusan Perguruan Tinggi siap untuk bekerja di sektor konstruksi. Untuk menjembatani antara kesenjangan antara kompetensi lulusan suatu program pendidikan tinggi dengan kompetensi keahlian maka harus ada sistem akreditasi yang saling menunjang antara sistem akreditasi pendidikan dan sistem akreditasi profesi dan memasukan pendidikan profesi kedalam kurikulum pembelajaran. Variabel yang berpengaruh signifikan terhadap kualitas pendidikan tinggi adalah dosen, kurikulum, mahasiswa, proses pembelajaran, dan sarana/prasarana. Strategi untuk meningkatkan kualitas pendidikan tinggi adalah memperhatikan peraturan yang mengatur tentang pendidikan tinggi, dengan melihat potret kesenjangan antara kompetensi lulusan pendidikan tinggi dengan kompetensi tenaga ahli konstruksi, untuk meningkatkan kualitas dosen, kurikulum, mahasiswa, proses pembelajaran dan sarana/prasarana.

Abstract

Beton bertulang adalah suatu campuran yang terdiri dari pasir, batu pecah, atau agregat-agregat lain yang dicampur menjadi satu dengan suatu pasta yang terbuat dari semen dan air yang membentuk suatu masa mirip batuan. Sifat dari beton yaitu kuat terhadap tekan dan lemah terhadap tarik, oleh karena itu dibutuhkan tulangan baja untuk melengkapi kelemahan dari beton tersebut yang lemah terhadap tarik, yang mana sifat dari tulangan baja itu sendiri adalah kuat terhadap tarik. Beton bertulang mempunyai ketahanan yang tinggi terhadap api dan air, bahkan merupakan bahan struktur yang baik untuk struktur bangunan yang banyak bersentuhan dengan air. Pada peristiwa dengan intensitas rata-rata, batang-batang struktur dengan ketebalan penutup beton yang memadai sebagai pelindung tulangan. Material beton bertulang ini bisa dibuat dari bahan-bahan lokal yang murah, seperti pasir, kerikil, dan air, dan relatif hanya membutuhkan sedikit semen dan tulangan baja Tujuan dalam penelitian ini adalah merencanakan dan menganalisa dimensi kolom, balok dan pelat terhadap gedung bertingkat tujuh lantai. Serta, menganalisa dan membandingkan bermacam-macam mutu beton terhadap biaya yang ditimbulkan, Mutu beton tersebut yang diteliti antara lain K-300, K-350, K400, K-500. Dari keempat mutu beton yang diteliti manakah yang paling murah. Berdasarkan perhitungan yang telah dilakukan mutu beton dengan harga yang paling murah adalah mutu beton K-300.

Abstract

Waste management is a pressing issue in Probolinggo Regency and City, necessitating swift action to mitigate environmental impacts. The construction of the Probolinggo Regional Waste Landfill (TPA) aims to address this challenge through cross-regional sanitation services. Proper financing is crucial for successful infrastructure development, and this study compares government budget (APBN/APBD) and non-government (regional loans) financing schemes. Utilizing a quantitative approach with primary and secondary data, the analysis indicates the viability of both financing options. Government-sourced investment shows an NPV of Rp 431,148,007,790, IRR 40.55%, BCR 1.07, and a 3-year payback period. Meanwhile, non-government or regional loans exhibit an NPV of Rp 110,115,495,905, IRR 9.03%, BCR 1.3, and a 9-year payback period. The decision-making process, weighing financial and non-financial criteria, favors regional loans/loans as the preferred financing scheme for the Probolinggo TPASR project. This research emphasizes the importance of a well-selected financing scheme to ensure the success and sustainability of the Probolinggo Regional Waste Landfill infrastructure.

Abstract

Contractors involved in construction projects face the crucial challenge of effectively managing time to ensure the timely completion of the project as stipulated in the contract, if not earlier. Efficient time management not only facilitates adherence to contractual obligations but also transforms incurred costs into profitable outcomes, thereby preventing financial penalties associated with project delays. Consequently, the strategic implementation of acceleration efforts emerges as a pivotal solution to address and mitigate the complexities inherent in construction project timelines. The acceleration process is intricately tied to the identification and prioritization of critical activities within the project schedule. By employing a comprehensive approach that integrates both cost and time analyses, the Crashing method with additional modifications emerges as a valuable tool in this endeavor. The Crashing method involves a strategic acceleration of critical activities, coupled with a meticulous calculation of the additional costs incurred due to the acceleration process. A compelling case study that exemplifies the efficacy of the Crashing method and its supplementary measure of alternative overtime work is evident in the Tanjung Uncang Pier construction project in Batam City. Through the meticulous application of the Crashing method and the incorporation of alternative overtime work, the project's completion timeline was successfully curtailed from the originally delayed schedule of 257 calendar days to a more expedited 244 calendar days.

Abstract

The economic slowdown due to the pandemic has negatively affected various sectors in Indonesia, including the real estate sector. Meanwhile, Java Island is still the center of the economy in Indonesia. This contrasts the conditions of regions outside Java, which are still experiencing development gaps. Despite being a minor contributor to GDP, areas outside Java, such as Maluku and Papua, have experienced rapid economic growth. This proves that, outside Java, there is still significant potential for growth and investment, although it is inevitable that it will face unique challenges and obstacles in the future. Some of the factors that cause this to happen are the lack of supporting infrastructure such as roads, limited skilled human resources, and connectivity and transportation mobilization in the area. Excellent and appropriate connectivity and mobilization are needed to support economic growth in an area. One option for mobilization tools for archipelagic countries like Indonesia is sea transportation. In meeting the needs of the property and real estate sector, sea transportation is one of the options of choice. Excellent and proper connectivity and mobilization can be a factor that supports economic growth as well as the real estate sector outside Java. In the real estate sector, maritime transportation is essential in the timely distribution of quality building materials and construction equipment to development sites. There is undoubtedly a link between marine transportation and property/real estate in Indonesia. The research method used in this study is a significant correlation analysis, namely Pearson Product Moment, to determine the relationship between two variables, namely Domestic Sea Transportation and Real Estate Sector GRDP. The results of the correlation data test in this study show that the Domestic Sea Transportation variable is positively correlated with the Real Estate GRDP variable. Indicated by the correlation coefficient value for each sea transportation variable of domestic ship visits (units) = 0.331, domestic ship visits (GT) = 0.504, the flow of Non-Crate and Container goods (unloading) = 0.251, the flow of Non-Crate and Container goods (loading) = 0.447. It can be interpreted that there is a positive relationship between the four sea transportation variables and Real Estate GRDP.
