Abstract

Proyek perumahan X di Kecamatan Cerme, Kabupaten Gresik, merupakan proyek pembangunan yang bertujuan untuk menyediakan hunian berkualitas dengan biaya terjangkau. Namun, dalam pelaksanaannya, proyek ini menghadapi tantangan dalam pengelolaan waktu dan biaya. Penelitian ini dilakukan untuk menganalisis efektivitas metode critical path method (CPM) dan time-cost trade-off dalam mempercepat penyelesaian proyek tanpa menyebabkan lonjakan biaya yang signifikan. Metode penelitian yang digunakan adalah pendekatan kuantitatif dengan mengumpulkan data proyek melalui survei, wawancara dengan kontraktor, serta analisis dokumen proyek. Data yang diperoleh dianalisis menggunakan metode CPM untuk mengidentifikasi jalur kritis yang mempengaruhi durasi proyek, sementara metode time-cost trade-off digunakan untuk mengevaluasi pengaruh percepatan waktu terhadap biaya konstruksi. Hasil penelitian menunjukkan bahwa proyek yang semula direncanakan selesai dalam 90 hari mengalami keterlambatan dan baru selesai dalam 100 hari. Dengan penerapan metode CPM dan time-cost trade-off, durasi proyek dapat dipersingkat menjadi 84 hari dengan menambahkan 1 jam lembur per hari, 80 hari dengan 2 jam lembur, dan 78 hari dengan 3 jam lembur. Meskipun percepatan ini meningkatkan biaya konstruksi, perhitungan menunjukkan bahwa kenaikan biaya tetap berada dalam batas yang dapat diterima. Penelitian ini memberikan rekomendasi bagi kontraktor dan pengembang dalam mengoptimalkan perencanaan proyek untuk meminimalkan keterlambatan dan pengeluaran tambahan. Penerapan metode CPM dan time-cost trade-off terbukti dapat menjadi solusi efektif dalam meningkatkan efisiensi waktu dan biaya proyek konstruksi.

Abstract

The biggest waste in Indonesia is plastic waste, even though the government has stopped using plastic bags in minimarkets, plastic waste is still the biggest waste in Indonesia. One way to handle plastic waste is by recycling, such as recycling plastic bottles through ecobricks. Ecobricks themselves are to overcome the problem of plastic waste by collecting, cleaning and packaging plastic into very dense plastic bottles. Its function is to extend the life of the plastic by processing it into something that can be used or is useful. The method used is counseling in the form of socializing ecobricks in the form of chairs which will be socialized on how to make and use them in the Pongangan Rejo area, Manyar District, Gresik Regency with the aim of the community being creative and innovative in utilizing plastic waste and protecting the surrounding environment. The results obtained are that the community can make good use of plastic waste, and are able to make ecobrick products in the form of chairs or anything else, both for personal needs and for the surrounding community.

Abstract

Proses perencanaan hingga pengendalian proyek selama pelaksanaan pekerjaan konstruksi merupakan kegiatan penting dari suatu proyek. Keberhasilan atau kegagalan dari suatu proyek dapat disebabkan perencanaan yang tidak matang serta pengendalian yang kurang efektif, sehingga kegiatan proyek tidak efisien. Hal tersebut akan mengakibatkan keterlambatan, menurunnya kualitas, dan meningkatnya biaya pelaksanaan. Waktu kerja manajemen proyek juga dibatasi oleh jadwal yang ditentukan sehingga pimpinan yang terlibat dalam proyek harus dapat mengantisipasi perubahan kondisi yang terjadi. Proyek yang menjadi objek penelitian penulis adalah proyek Lanjutan Gedung Kuliah Jurusan Teknik Listrik Industri yang terletak di Jalan Raya Taddan Camplong Sampang Kab. Sampang – Madura, Propinsi Jawa Timur.Metode CPM/critical path method dapat digunakan untuk mengatur waktu penyelesaian proyek dengan lebih efisien dan efektif. Untuk dapat mengurangi dampak keterlambatan dan pembengkakan biaya proyek diusulkan proses crashing dengan diberlakukan kerja lembur. Percepatan durasi dilakukan pada pekerjaan pekerjaan yang berada di lintasan kritis.Berdasarkan Hasil penelitian dengan Metode CPM menunjukkan durasi optimal proyek adalah 100 hari dengan efisiensi waktu selama 20 hari atau sebesar 16,67 % dan total biaya Rp 13,151,987,714.31 dengan efisiensi biaya sebesar Rp 451,447,852.22 atau 3,32 %.

Abstract

Tenaga listrik merupakan sumber energi yang sangat penting bagi kehidupan manusia baik untuk kegiatan industri, kegiatan komersial maupun dalam kehidupan sehari-hari rumah tangga. Energi listrik dibutuhkan untuk memenuhi kebutuhan penerangan dan juga proses produksi yang melibatkan barang-barang elektronik dan alat-alat/mesin industri. Mengingat begitu besar dan pentingnya manfaat energi listrik sedangkan sumber energi pembangkit listrik terutama yang berasal dari sumber daya tak terbarui keberadaannya terbatas, maka untuk menjaga kelestarian sumber energi ini perlu diupayakan langkah-langkah strategis yang dapat menunjang penyediaan energy listrik secara optimal dan terjangkau. Oleh karena itu, kerjasama dan partisipasi berbagai pihak sangat diperlukan untuk mengatasi krisis energi listrik ini. Misalnya saja pada perusahaan baja, dimana pada proses produksinya yakni pemanasan atau perubahan dari scrap ke cairan baja sangat bergantung pada energi listrik. Adapun langkah yang dapat dilakukan oleh sebuah perusahaan untuk menghemat energi tersebut adalah dengan cara mengoptimalkan suhu pemanasan sehingga didapatkan cairan baja dengan suhu yang tepat dan tidak memerlukan panas yang berlebihan. Pengaturan suhu juga sangatlah vital karena setelah berada di CCM liquid metal tidak dapat dikembalikan lagi. Metode fuzzy – mamdani dapat digunakan untuk menyelesaikan masalah optimasi suhu ladle pada baja low carbon. Berdasarkan hasil penelitian didapatkan suhu yang optimal untuk baja low carbon antara 15850C-15950C tergantung pada kandungan carbon dan liquid temperature setiap grade nya.

Abstract

The village has potential natural resources in agriculture and aquaculture ponds. Potential agriculture and ponds use a rainfed system to irrigate rice fields and ponds. In addition, Kambingan Village already has a permanent irrigation network. Cerme people certainly understand the access to Kambingan Village, but people from outside Cerme Subdistrict certainly need signage to Kambingan Village so they don't miss it when visiting the village. The type of road pavement entering the village is divided into 2 (two) types, namely paving pavement and asphalt pavement. The condition of the asphalt pavement is good, while the condition of the paving pavement is bumpy. The activity method in community service in Kambingan Village is the science and technology simulation method, where students redesign signage using design applications to create design concepts and engineering equipment for the fabrication and installation of signage. The stages carried out include identifying problems in the field, coordinating with the Village Chief, redesigning the signage board, fabricating the signage board, removing the old signage board, and installing new signage at a point determined by the Village Chief. The expected result is that the community gets information on directions to enter Kambingan Village through the installation of a new signage board and adds color or karaktek to the road shoulder from Cerme District to Benjeng District.

Abstract

Iker-iker Geger Village is a village located in Cerme District, Gresik Regency. that often experiences seasonal flooding due to rainwater runoff that cannot be absorbed optimally by the soil, especially during high rainfall in the rainy season. The flat topography, clay soil type, and suboptimal drainage system exacerbate this condition. In addition, household organic waste management in the village is still limited, with most waste being burnt or dumped into waterways, contributing to drainage blockages and environmental pollution. These problems require a simple yet impactful approach, one of which is through the application of biopore infiltration pit technology that has proven effective in increasing groundwater absorption, reducing the volume of surface runoff, as well as processing organic waste into compost that is beneficial for local agriculture. This community service program aims to provide education and direct assistance to the people of Iker-Iker Geger Village in making and utilizing biopores as a sustainable environmental solution. This activity involves elements of the community, village officials, and students, with a participatory approach that is expected to increase environmental awareness and encourage village independence in overcoming the problems of inundation and organic waste. Through this program, the community not only gained technical skills but also instilled a spirit of mutual cooperation in protecting the environment, in line with the principles of sustainable development and local wisdom.
