Abstract

AbstrakBendungan Tigadihaji merupakan infrastruktur strategis untuk irigasi, penyediaan air baku, PLTA, dan pengendalian banjir di Sumatera Selatan. Proyek Paket 1 mengalami keterlambatan signifikan sehingga memerlukan strategi percepatan yang efektif. Penelitian ini bertujuan mengevaluasi tiga alternatif percepatan, yaitu crashing (penambahan jam kerja/lembur), overlapping (pengubahan hubungan antaraktivitas), dan kombinasi keduanya, dengan mengukur dampak terhadap durasi serta biaya proyek. Analisis dilakukan menggunakan metode jalur kritis (CPM) berbasis data jadwal dan biaya kontrak. Percepatan dihitung dari perbedaan durasi total proyek serta perubahan biaya langsung dan tidak langsung. Hasil menunjukkan bahwa crashing dapat memperpendek durasi sebesar 191 hari dengan efisiensi biaya sekitar Rp2,45 miliar. Metode overlapping mempercepat 115 hari dengan efisiensi Rp2,05 miliar. Strategi kombinasi memberikan hasil terbaik dengan percepatan 321 hari dan efisiensi Rp4,76 miliar. Temuan ini menegaskan bahwa kombinasi crashing dan overlapping merupakan pilihan paling optimal dalam percepatan proyek berskala besar. Implikasi praktisnya, kontraktor dan pemilik proyek dapat menghemat waktu hampir satu tahun dengan tambahan biaya yang relatif kecil, sehingga risiko keterlambatan lebih lanjut dapat ditekan. Bagi pengambil kebijakan, hasil ini menunjukkan perlunya dukungan regulasi dan pengendalian mutu yang lebih adaptif agar strategi percepatan dapat diimplementasikan tanpa mengurangi keselamatan maupun kualitas konstruksi. Dari perspektif tata ruang, percepatan penyelesaian bendungan mempercepat pula penyediaan infrastruktur dasar yang mendukung produktivitas pertanian, ketahanan air, dan pengembangan wilayah.Kata kunci: Crashing; Overlapping; Bendungan Tigadihaji AbstractThe Tigadihaji Dam is a strategic infrastructure for irrigation, raw water supply, hydroelectric power (PLTA), and flood control in South Sumatra. Package 1 of the project has encountered significant delays, necessitating effective acceleration strategies. This study aims to evaluate three acceleration alternatives: crashing (adding work hours/overtime), overlapping (modifying inter-activity relationships), and their combination, measuring impacts on project duration and cost. The analysis uses the Critical Path Method (CPM) based on contractual scheduling and cost data. Acceleration is measured as the difference in total project duration and changes in direct and indirect costs. Results show that crashing can reduce the project duration by 191 days with a cost saving of approximately Rp2.45 billion. The overlapping method accelerates the schedule by 115 days with savings of Rp2.05 billion. The combination strategy achieves the best result: 321 days of acceleration with efficiency of Rp4.76 billion. These findings confirm that the combination of crashing and overlapping is the optimal method for accelerating large-scale projects. In practice, contractors and project owners can save almost one year with relatively modest additional costs, thereby mitigating further delay risks. For policymakers, these results indicate the need for adaptive regulation and quality control so that acceleration strategies can be implemented without compromising safety or construction quality. From a spatial planning perspective, accelerated completion of the dam also speeds up the provision of basic infrastructure that supports agricultural productivity, water security, and regional development.Keywords: Crashing; Overlapping; Tigadihaji Dam

Abstract

ABSTRACTFlood control in the coastal areas of Central Java, particularly along the SWD 1 Channel and the Goleng Spillway, faces significant hydraulic challenges due to sedimentation and land-use changes. This study aims to evaluate the hydraulic capacity of the Goleng Spillway and the SWD 1 Channel in reducing the Q25 flood discharge from the Wulan River, as well as to identify critical overflow points and effective mitigation scenarios. Hydraulic simulations were conducted using the HEC-RAS software under three scenarios: (1) inflow from the Goleng Spillway, (2) local flooding within the SWD 1 watershed, and (3) a combination of both. Input parameters included the Q25 design discharge, DEM-based topography, and cross-sectional channel geometry. The simulation results indicate that several cross-sections (from STA 0+025 to STA 31+000) are unable to accommodate the Q25 discharge effectively, with water surface elevations ranging from 1.18 to 7.9 meters. The most critical condition occurs along the left bank of SWD 1 due to the absence of embankment elevation. While the normalization design improved flow capacity, it was insufficient to manage the combined extreme inflows. Integrated structural interventions, such as elevating the left embankment and optimizing spillway geometry, are recommended to enhance flood resilience in the lower Wulan River region.Keywords: SWD 1, Goleng Spillway, flood, Q25, HEC-RAS, embankment, hydraulics. ABSTRAKPengendalian banjir di wilayah pesisir Jawa Tengah, khususnya di Sungai SWD 1 dan Pelimpah Goleng, menghadapi tantangan kapasitas hidrolika akibat sedimentasi dan perubahan tata guna lahan. Penelitian ini bertujuan untuk mengevaluasi kapasitas hidrolik Pelimpah Goleng dan Saluran SWD 1 dalam mereduksi debit banjir Q25 Sungai Wulan, serta mengidentifikasi titik-titik kritis luapan dan skenario mitigasi efektif. Simulasi hidrolika dilakukan menggunakan perangkat lunak HEC-RAS dengan tiga skenario: (1) inflow dari Pelimpah Goleng, (2) banjir lokal DAS SWD 1, dan (3) kombinasi keduanya. Parameter input meliputi debit desain Q25, topografi DEM, dan geometri penampang saluran. Hasil simulasi menunjukkan bahwa beberapa penampang (STA 0+025 hingga STA 31+000) tidak mampu menampung debit Q25 secara optimal, dengan muka air mencapai 1,18–7,9 m. Kondisi paling kritis terjadi pada sisi kiri SWD 1 akibat ketiadaan peninggian tanggul. Desain normalisasi terbukti meningkatkan kapasitas, tetapi tidak cukup mengatasi kombinasi inflow ekstrem. Intervensi struktural terintegrasi, seperti peninggian tanggul kiri dan optimalisasi geometri pelimpah, disarankan untuk memperkuat ketahanan banjir wilayah hilir Sungai Wulan.Kata Kunci: SWD 1, Pelimpah Goleng, banjir, Q25, HEC-RAS, tanggul, hidrolika.

Abstract

Abstract. This study examines the effect of sustainability reports on financial performance with firm size as a moderating variable. The independent variable is the Sustainability Report which is measured using GRI standards. The dependent variable is financial performance as measured using ROA. The Moderating Variable is firm size as measured using LnTotal Assets. The research sample consists of banking companies listed on the Indonesia Stock Exchange during 2020-2023. Purposive sampling method was used to determine the research sample. The sample used was 15 companies in the 2020-2023 period. Data obtained from the Sustainability report and the Company's annual report. Data processing uses STATA 17. The results of this research show that sustainability reports have a positive and significant effect on financial performance, while company size as a moderating variable is not significant on the relationship between sustainability reports and financial performance.

Abstract

ABSTRAKIndustri konstruksi di Indonesia menyumbang sekitar 30% dari total kecelakaan kerja nasional, yang sebagian besar disebabkan oleh pekerjaan berisiko tinggi. Penelitian ini mengevaluasi implementasi ISO 45001:2018 pada proyek Pembangunan Jembatan Kaca Bendungan Sukamahi, dengan pendekatan kuantitatif berbasis evaluasi praktis dan perhitungan Relative Importance Index (RII). Hasil menunjukkan mayoritas prosedur keselamatan telah diterapkan dengan baik, seperti briefing keselamatan sebelum bekerja (RII = 0,93), namun komunikasi bahaya kerja masih menjadi tantangan (RII = 0,886). Solusi paling efektif adalah pemberian insentif kepada pekerja yang mematuhi prosedur K3 (RII = 0,928). Penelitian ini berkontribusi dalam memperluas kajian penerapan ISO 45001:2018 di sektor konstruksi Indonesia, khususnya melalui pendekatan berbasis metrik dan identifikasi praktis, yang masih terbatas dalam literatur lokal. Temuan ini juga memberikan implikasi kebijakan bagi perusahaan konstruksi dan pemangku kepentingan untuk mengembangkan strategi implementasi K3 yang lebih adaptif dan terukur. Penerapan K3 yang efektif menjadi bagian integral dari perencanaan infrastruktur yang aman, berkelanjutan, dan selaras dengan pengelolaan ruang proyek.Kata Kunci: ISO 45001:2018, Proyek Konstruksi, Manajemen K3, Risiko Kecelakaan ABSTRACTThe construction industry in Indonesia accounts for approximately 30% of total national workplace accidents, most of which are attributed to high-risk activities. This study evaluates the implementation of ISO 45001:2018 in the Glass Bridge Construction Project at the Sukamahi Dam, using a quantitative approach based on practical evaluation and the Relative Importance Index (RII) method. The results indicate that most safety procedures have been properly implemented, such as pre-work safety briefings (RII = 0.93); however, hazard communication remains a challenge (RII = 0.886). The most effective solution identified is the provision of incentives for workers who comply with occupational health and safety (OHS) procedures (RII = 0.928). This study contributes to the growing body of research on ISO 45001:2018 implementation in Indonesia’s construction sector, particularly through metric-based evaluation and practical identification, which remain limited in local literature. The findings also provide policy implications for construction companies and stakeholders to develop more adaptive and measurable OHS implementation strategies. Effective OHS implementation is an integral part of safe, sustainable infrastructure planning that aligns with spatial and site management principles.Keywords: ISO 45001:2018, Construction Project, OHS Management, Accident Risk

Abstract

ABSTRAKKepadatan penduduk di suatu daerah seringkali memicu terjadinya alih fungsi lahan. Kondisi ini kemudian berdampak pada aspek ekonomi. Penelitian ini bertujuan untuk menganalisis perubahan penggunaan lahan pertanian dan mengidentifikasi faktor serta dampak ekonominya. Studi ini penting untuk memahami efek jangka panjang alih fungsi lahan terhadap keberlanjutan lingkungan dan kesejahteraan masyarakat. Metode yang digunakan meliputi analisis data deskriptif kuantitatif, teknik overlay untuk melihat perubahan penggunaan lahan, serta uji Chi-Square guna menentukan faktor dan dampak ekonomi dari alih fungsi lahan pertanian. Hasil menunjukkan lahan pertanian menurun dari 7625,70 Ha (83,01%) pada 2014 menjadi 7164,44 Ha (77,99%) pada 2024 sementara lahan permukiman meningkat dari 562,86 Ha (6,13%) menjadi 860,38 Ha (9,37%). Faktor utama yang memengaruhi alih fungsi lahan meliputi jumlah dan kepadatan penduduk, pendidikan petani, infrastruktur, harga lahan, pendapatan, kebijakan, dan penyerapan tenaga kerja. Dampak positif dari segi ekonomi adalah terbukanya lapangan pekerjaan baru dan pergeseran struktur ekonomi masyarakat dari sektor pertanian menjadi sektor industri dan jasa. Dampak negatifnya berupa penyusutan lahan pertanian yang mengancam produksi pangan, memicu kenaikan harga bahan pokok, dan mengganggu kestabilan ekonomi petani. Penelitian ini penting bagi negara berkembang untuk memahami dampak jangka panjang alih fungsi lahan terhadap keberlanjutan lingkungan dan kesejahteraan masyarakat, serta sebagai pertimbangan dalam pengambilan keputusan lahan.Kata Kunci: Perubahan Penggunaan lahan, Analisis Spasial, Alih Fungsi Lahan Pertanian, Dampak Ekonomi ABSTRACTPopulation density in an area often triggers land use change. This condition then has an impact on economic aspects. This study aims to analyze changes in agricultural land use and identify the factors and economic impacts. This study is important for understanding the long-term effects of land use change on environmental sustainability and community welfare. The methods used include quantitative descriptive data analysis, overlay techniques to observe changes in land use, and Chi-Square tests to determine the factors and economic impacts of agricultural land use change. The results show that agricultural land decreased from 7625.70 Ha (83.01%) in 2014 to 7164.44 Ha (77.99%) in 2024, while residential land increased from 562.86 Ha (6.13%) to 860.38 Ha (9.37%). The main factors influencing land conversion include population size and density, farmer education, infrastructure, land prices, income, policy, and labor absorption. The positive economic impact is the creation of new jobs and a shift in the community's economic structure from the agricultural sector to the industrial and service sectors. The negative impact is the reduction of agricultural land, which threatens food production, triggers an increase in the price of basic commodities, and disrupts the economic stability of farmers. This research is important for developing countries to understand the long-term impact of land conversion on environmental sustainability and welfare, as well as for consideration in land use decision-making.Keywords: Land Use Change, Agricultural Land Conversion, Spatial Analysis, Economic Impact

Abstract

ABSTRACTBogor Regency is characterized by diverse patterns of regional development across its different areas. In the western part of Bogor, the proportion of built-up land is the lowest, yet the poverty rate is the highest compared to other parts of the regency. Conversely, Eastern Bogor has the largest share of built-up land and records the lowest poverty rate. Based on this phenomenon, the present study aims to analyze the relationship between built-up land and poverty levels, as well as to assess its implications within the framework of spatial justice. This research employs a quantitative approach using Spearman’s correlation analysis and spatial analysis with ArcGIS, drawing on secondary data from 40 districts in Bogor Regency in 2022. Compared to previous studies on spatial justice, this study is among the first to explicitly examine the relationship between spatial justice and social inequality in the context of differing regional growth characteristics, particularly between Western and Eastern Bogor. The findings reveal a significant negative relationship between built-up land and poverty levels, although the correlation strength is moderate. In addition, built-up land is found to be positively and significantly correlated with total population and the availability of public facilities, while its relationship with population density is not statistically significant. These results reinforce the importance of spatial justice, particularly distributive and procedural justice in promoting more balanced development. The planned administrative division of Bogor Regency must therefore consider the spatial justice dimension to avoid exacerbating existing disparities. Accordingly, data-driven and participatory spatial planning is expected to serve as an instrument to foster more equitable and inclusive development.Keywords: spatial justice, built-up land, poverty alleviation, regional disparity, GIS analysis, Bogor Regency ABSTRAKKabupaten Bogor merupakan daerah yang memiliki karakteristik perkembangan daerah yang berdagam tiap segmen daerahnya. Terlihat bahwa daerah Bogor bagian barat memiliki jumlah lahan terbangun paling rendah namun memiliki tingkat kemiskinan tertinggi dibandingkan daerah bagian lainnya. Kondisi ini terjadi pula pada bagian Bogor Timur memiliki jumlah lahan terbangun terbanyak dengan tingkat kemiskinan terendah. Berdasarkan fenomena tersebut, penelitian ini bertujuan untuk menganalisis hubungan antara luas lahan terbangun dan tingkat kemiskinan, serta menilai implikasinya dalam kerangka keadilan spasial. Penelitian ini menggunakan pendekatan kuantitatif dengan analisis korelasi Spearman dan analisis spasial berbasis perangkat lunak ArcGIS, penelitian ini memanfaatkan data sekunder dari 40 kecamatan di Kabupaten Bogor tahun 2022. Jika dibandingkan studi keadilan spasial sebelumnya, penelitian ini merupakan salah satu studi yang secara eksplisit mengkaji hubungan antara keadilan spasial dan ketimpangan sosial dalam konteks perbedaan karakteristik pertumbuhan wilayah, khususnya antara Bogor Barat dan Bogor Timur. Hasil penelitian menunjukkan terdapat hubungan negatif yang signifikan antara lahan terbangun dan tingkat kemiskinan, meskipun kekuatan korelasinya tergolong sedang. Selain itu, lahan terbangun juga berkorelasi positif dan signifikan dengan jumlah penduduk dan ketersediaan fasilitas publik, sementara hubungan dengan kepadatan penduduk tidak signifikan secara statistik. Temuan ini mempertegas pentingnya prinsip keadilan spasial, khususnya keadilan distributif dan prosedural, dalam upaya pemerataan pembangunan. Pemekaran wilayah Kabupaten Bogor yang direncanakan harus mempertimbangkan dimensi keadilan spasial agar tidak memperparah ketimpangan yang telah ada. Dengan demikian, tata ruang yang berbasis data dan partisipatif diharapkan mampu menjadi instrumen untuk mendorong pembangunan yang lebih adil dan inklusif.Kata kunci: keadilan spasial, lahan terbangun, pengentasan kemiskinan, ketimpangan wilayah, analisis SIG, Kabupaten Bogor

Abstract

Abstract. Waste volume in Karawang City that can be handled will only be 40% and the other 60% will be managed by waste banks and temporary shelter. Innovation in waste recycling is needed, one of which is making plastic waste as raw material for paving block production. This research aims to assess how using plastic waste as a material in making paving blocks affects their compressive strength and water absorption, with the potential to reduce overall plastic waste and explore alternatives to conventional materials. This research focuses on testing water absorption capacity and compressive strength based on SNI 03–0691–1996 standards for making paving blocks. The water absorption test results on PVG 1 and 2 are up to 38.46% larger than PVG 3 and 4 because there are many cavities in PVG 1 and 2 that making were below standard, and PVG 3 and 4 were at quality standard level B. The compressive quality test of PVG 1 and 2 have a more noticeable compressive quality regard with a typical regard of 6,075 MPa compared to clearing squares with a full plastic composition with an ordinary regard of 4,745 MPa. It happens since of insufficient and manual burning, but it can too be caused by an ought to utilize plastic waste and the got to age the clearing squares being attempted. When compared with the quality Indonesian National Standard (SNI 03 - 0691 – 1996), the compressive quality test of the clearing inside the examination did not meet the standard.Keywords: Plastic Waste, Paving Block, Water Absorption Test, Compressive Strength
