Abstract

Keterlambatan waktu pelaksanaan proyek konstruksi menimbulkan banyak sekali kerugian, bukan hanya dari waktu, tapi juga dari segi biaya. Keterlambatan ini juga terjadi pada proyek Rehabilitasi Jaringan Irigasi D. I Ponre-Ponre Kab. Bone yang mengalami keterlambatan waktu pelaksanaan sebesar 3,16% akibat banyaknya kelonggaran waktu pada jadwal pelaksanaan. Salah satu upaya untuk mengatasi keterlambatan pada proyek yaitu dengan mempercepat durasi pekerjaan sehingga kelonggaran waktu bisa diminimalisir. Percepatan waktu diperlukan untuk mengatasi keterlambatan waktu salah satunya dengan mempercepat penggunaan material dan tenaga kerja. Untuk itu tujuan penelitian adalah mengetahui seberapa besar percepatan panggunaan material dan tenaga kerja. Metode penelitian yaitu dengan menggunakan network planning untuk mempercepat durasi dengan cara mempercepat penggunaan material dan tenaga kerja. Network planning awal dibuat berdasarkan data sekunder, lalu dibuat network planning hasil percepatan durasi pekerjaan dengan percepatan penggunaan material dan tenaga kerja, lalu membandingkan hasil tersebut. Dari jadwal awal durasi penyelesaian pekerjaan yaitu 271 hari kalender, sedangkan setelah dipercepat dengan metode Network Planning, durasi penyelesaian menjadi 258 hari. Proyek mengalami percepatan durasi sebesar 13 hari penyelesaian atau mengalami percepatan durasi pelaksanaan sebesar 4.8% dan disertai dengan penggunaan material dan sumber daya yang lebih efektif.

Abstract

ABSTRAK Penelitian ini bertujuan untuk menganalisis tingkat performa atlet cricket nasional Indonesia berdasarkan aspek fisik, fisiologis dan keterampilan teknis. Penelitian ini menggunakan metode survei dengan teknik tes dan pengukuran. Pengumpulan data dilakukan dengan tes kebugaran jasmani spesifik. Adapun hasil penelitian ini menunjukkan bahwa rata-rata kecepatan sprint 4,72 ± 0,28 detik, daya tahan otot tungkai 45,3 ± 5,7 cm, jarak tempuh yo yo test mencapai 1.320 ± 180 meter dengan estimasi VO₂max sebesar 48,6 ± 3,2 ml/kg/menit. Pada aspek teknis, akurasi batting rata-rata mencapai 78,5 ± 6,4% dan kecepatan bowling sebesar 114,2 ± 8,6 km/jam, sementara waktu reaksi rata-rata tercatat 0,29 ± 0,03 detik. Analisis perbandingan antarposisi menunjukkan bahwa bowler unggul pada kecepatan dan daya ledak, batsman unggul pada akurasi dan waktu reaksi, sedangkan all-rounder memiliki profil performa paling seimbang. Perbedaan performa antarposisi tersebut signifikan secara statistik (p<0,05). Jika dibandingkan dengan standar internasional, performa atlet cricket nasional Indonesia berada pada kategori baik, namun masih terdapat kesenjangan pada aspek daya tahan aerobik dan power output. Kesimpulan penelitian ini menegaskan bahwa peran posisi berpengaruh terhadap profil performa atlet cricket nasional, sehingga diperlukan program latihan yang lebih spesifik, terintegrasi, dan berbasis kebutuhan posisi untuk meningkatkan performa menuju level internasional. Kata Kunci: Cricket, Performa Atlet, Kondisi Fisik, Fisiologis, Keterampilan Teknis, Tim Nasional ABSTRACT This study aims to analyze the performance level of Indonesian national cricket athletes based on physical, physiological and technical skill aspects. This study uses a survey method with test and measurement techniques. Data collection was carried out with specific physical fitness tests. The results of this study showed that the average sprint speed was 4.72 ± 0.28 seconds, leg muscle endurance 45.3 ± 5.7 cm, the distance traveled by the yo yo test reached 1,320 ± 180 meters with an estimated VO₂max of 48.6 ± 3.2 ml/kg/minute. In the technical aspect, the average batting accuracy reached 78.5 ± 6.4% and bowling speed was 114.2 ± 8.6 km/h, while the average reaction time was recorded at 0.29 ± 0.03 seconds. A comparative analysis of the positions shows that the bowler excels in speed and explosiveness, the batsman excels in accuracy and reaction time, while the all-rounder has the most balanced performance profile. The difference in performance between these positions was statistically significant (p<0.05). When compared to international standards, the performance of Indonesian national cricketers is in the good category, but there is still a gap in the aspects of aerobic endurance and power output. The conclusion of this study emphasizes that the role of position affects the performance profile of national cricket athletes, so a more specific, integrated, and position-based training program is needed to improve performance towards the international level.

Abstract

The rapid growth of cryptocurrency markets has created new challenges in understanding and predicting the structural dynamics of digital asset prices. Bitcoin, as the most traded blockchain-based currency, exhibits extreme volatility, nonlinear patterns, and complex regime shifts that traditional financial models cannot adequately capture. This study proposes a hybrid analytical framework that integrates K Means clustering with the Hidden Markov Model to identify and model multiple market regimes in Bitcoin time series data. The Bitcoin dataset used in this research contains minute-level records that were preprocessed to extract key indicators, namely logarithmic returns and rolling volatility, which represent the short-term dynamics of market behavior. The K Means algorithm was first employed to segment the data into three distinct clusters that correspond to bullish, bearish, and sideways regimes, followed by the application of the Hidden Markov Model to estimate probabilistic transitions between these regimes over time. The results reveal that the hybrid K Means and Hidden Markov Model approach achieves superior performance compared to a standalone model, as indicated by a higher log likelihood and a lower Bayesian Information Criterion value. The transition probability matrix shows that bullish and bearish regimes are highly persistent, while the sideways regime acts as a transitional buffer that connects both market extremes. The empirical findings confirm that Bitcoin prices evolve through persistent and probabilistically determined regimes rather than random fluctuations. The proposed framework provides a more comprehensive understanding of cryptocurrency market dynamics and offers practical value for investors, risk analysts, and policymakers in designing adaptive trading and risk management strategies within blockchain-based financial ecosystems.

Abstract

Al-Ghazali in his works of Ihya Ulumuddin, al-Mustashfa Mizan, al-Amal and At-Tibr al-Masbuk fi al-Nasihah al-Mulk. In his works, Al-Ghazali explains many aspects of Islamic economics, especially Al-Ghazali's thoughts on the concept of money. This research aims to find out Imam Abu Hamid al-Ghazali's thoughts on the concept of money.  Al-Ghazali's thinking about the concept of money is inspired by the number of economic problems that occur in the barter system or exchange of goods. Al-Ghazali has explained several functions that money has, including as qiwam of al-dunya (unit of calculation), hakim mutawasith (measure of the value of goods), and al-mu'awwidlah (medium of exchange).

Abstract

Economics based on sharia has concepts and teachings that can provide welfare evenly to mankind. Therefore, the philosophy of Islamic economics is the main key in human economic development. The purpose of this paper is to discuss the existence of sharia economic philosophy in the modern era. The golden opportunity for the growth of Islamic Economics developed in Indonesia needs to be supported by knowing the western response to economic conditions in Indonesia, where the 4.0 revolution era is a challenge for Indonesia in the economic welfare of its people. Therefore, in order to find the response and contribution of Sharia economic philosophy to the western system that tends to be modern. This type of research is normative juridical and descriptive legal study. The results of the study found that Sharia economic philosophy has very strong energy to ensure that the modern economy is established and strong. Without a philosophical basis packed by Islamic values, the economic system looks weak. So that the Sharia economy in Indonesia is embracing the Indonesian sharia economy with the aim of re-controlling the indo pacific, by implementing a free market and capitalist system. However, Indonesia remains in principle, namely developing the potential of the Islamic economy because this is a golden opportunity towards an established and progressive Indonesia.
