Abstract

Mangroves have several functions, including maintaining biological balance in coastal ecosystems and tourism. On the other hand, mangroves are also very vulnerable to natural disturbances, anthropogenic, land conversion, and even pollution from various human activities. The success of mangrove planting activities does not only depend on the selection of the type of mangrove to be planted, but also on the selection of a suitable location to support its growth. Mangroves in Romokalisari Village, Surabaya are currently still relatively few. This needs to be planted because the mangroves function as wave breakers and tourist attractions. Mangrove planting activities in Romokalisari Village, Surabaya, were carried out by residents, lecturers and students of the Surabaya State Polytechnic of Shipping. The results of the mangrove planting are expected to have a positive impact on Romokalisari Village, Surabaya and its surroundings.

Abstract

Perintis sea transportation is one of the government programs specifically to support 3TP regional connectivity. One of the implementation locations is in Pangkalan Ambon, Maluku Province, supported by a state subsidy budget. The results of the actualization of the program showed that several route segments were overlapping, cargo and passenger occupancy was not optimal and other technical problems. Given these problems, research was carried out to evaluate programs and efforts to optimize pioneering sea transportation. This research aims to provide modeling for measuring the effectiveness and optimization efforts carried out so that the useful value of the pilot program can increase. The method used in this research is quantitative descriptive. The results of this research show that there are five indicators in selecting effectiveness, including annual frequency, total operating time, number of goods, number of passengers and ship load factor. Based on the calculations and modeling that have been carried out, of the 17 route sections, there are 4 route sections that are ineffective, 3 route sections are quite effective, and 10 route sections are effective. To increase this effectiveness, investigative efforts that can be carried out include local regional government coordination by exploring regional potential, improving supporting facilities and infrastructure and adding a team of perintis oordinators.

Abstract

Pelabuhan merupakan salah satu infrastruktur yang dapat mendukung Sistem Logistik Nasional di Indonesia dikarenakan Indonesia merupakan negara kepulauan. Adanya pelabuhan juga dapat mendukung pertumbuhan ekonomi di wilayah Indonesia. Salah satu syarat untuk dapat melakukan kegiatan kepelabuhanan dengan melakukan konsesi telah diatur pada UU Pelayaran No. 17 Tahun 2008 Pasal 92. Menurut Badan Pemeriksa Keuangan (BPK) untuk saat ini kinerja pengelolaan konsesi pelabuhan belum efektif. Selain itu, juga keluar Instruksi Menteri Perhubungan Republik Indonesia Nomor 6 Tahun 2018 tentang hasil pemeriksaan kinerja atas efektivitas pengelolaan konsesi pelabuhan di Terminal Teluk Lamong yang belum melakukan kajian secara mendalam terkait penentuan tarif sebesar 2,5% dan lama waktu konsesi. Penelitian ini bertujuan untuk memberikan model konsesi yang efektif dan saling menguntungkan antara pihak-pihak yang terlibat. Metode yang digunakan yaitu dengan menggunakan metode BCR (Benefit Cost Rasio) dan analisis sensitivitas. Dari hasil penelitian ini untuk komponen yang paling berpengaruh adalah tarif konsesi dan tarif pelabuhan. Kemudian untuk waktu konsesi dengan nilai BCR > 1 pada tahun ke 27 untuk payback period pada tahun ke 23 dan untuk lama konsesi yaitu 60 tahun dengan tarif konsesi 2,5% dari pendapatan pelabuhan.

Abstract

This study determined the optimal proportion of fly ash as a partial replacement for Portland cement in paving block mixtures to maximize compressive strength while supporting sustainability. Three fly ash substitution levels (10%, 20%, and 30% by cement weight) were evaluated. All mixtures met the K-300 standard (≥30.6 MPa), but the 20% substitution proved optimal, yielding the highest average compressive strength of 37.2 MPa with the lowest variation (CoV of 5.8%). The incorporation of fly ash also enhanced physical properties by reducing water absorption and porosity. The findings validate the use of fly ash for producing high-performance, environmentally friendly paving blocks that meet stringent quality standards.

Abstract

Modifikasi pada struktur deck house kapal tugboat dilakukan untuk memperbaiki akses tangga menuju ruang galley yang terlalu sempit. Namun, perubahan ini dapat memengaruhi kekuatan struktur kapal tugboat, khususnya pada frame 42 hingga 52. Oleh karena itu, dilakukan analisis kekuatan struktur menggunakan metode elemen hingga (Finite Element Method) berbasis software ANSYS. Pemodelan dilakukan dalam dua kondisi, yaitu sebelum dan sesudah modifikasi, dengan pembebanan utama berupa gaya towing sebesar 86268.28 N. Hasil simulasi menunjukkan bahwa tegangan maksimum meningkat dari 110.96 MPa menjadi 119.94 MPa, dan deformasi maksimum meningkat dari 0.37071 mm menjadi 0.48341 mm. Meskipun demikian, nilai tegangan tersebut masih berada di bawah tegangan ijin material sebesar 211.5 MPa, dan nilai safety factor sebesar 1.8 menunjukkan bahwa struktur tetap aman. Dengan demikian, dapat disimpulkan bahwa modifikasi deck house tidak menimbulkan risiko kegagalan struktur dan tetap memenuhi standar keselamatan sesuai aturan IRS (Indian Register of Shipping).

Abstract

As an archipelagic country, Indonesia has abundant natural resources and the potential to develop various industries. In this case, the Ministry of Industry still relies on Java as a location to encourage industrial activities in Indonesia. One of the largest industrial areas in Indonesia is located in the western area of Java Island, namely in the Pulogadung, Karawang, and Bekasi areas. Geographically, Indonesia, an archipelagic country, has good inter-island connectivity. The maritime transportation sector is a strategic component forming the national transportation system. Apart from that, the competitiveness of Indonesian commodities, goods, and services is developed due to national logistics prices, which are partly determined by transportation costs. The many commodities produced on Java Island have resulted in a high demand for goods from Java Island. The cost of shipping goods plays a significant role in the buyer's price. In this research, several options were analyzed for sending goods from Java to Sumatera, namely by using a truck and then crossing by ship from Merak Port to Bakauheni Port or sending by ship to Panjang Port, from Tanjung Priok Port or Ciwandan Port. This research was conducted to select a mode of transportation with a minimum unit cost to support delivery activities. Then, this research was carried out using an optimization method to make the shipping costs incurred more optimal. The results of this research will provide an analysis of the efficiency of intermodal transportation in transporting goods on the Java-Sumatera route.
