Abstract

Kapal laut telah dikenal lama sebagai alat transportasi yang menghubungkan antar pelabuhan. Pada saat ini bagian kapal sebagian besar terbuat dari logam yang disebabkan oleh faktor usian kapal atau akibat benturan menyebabkan korosi dan kerusakan pada bagian kapal. Untuk menjaga agar kapal tetap dapat beroperasi melayani penumpang, barang dan kendaraan maka kapal harus melakukan pemeliharaan dan perawatan. Kegiatan pemeliharaan dan perawatan salah satunya adalah replating yaitu proses pergantian dan pembaharuan pelat besi maupun plat baja yang baru untuk menggantikan pelat lama уаng telah mengalami penipisan diakibatkan korosi maupun deformasi terhadap air laut atau terkena benturan. Aktivitas replating ini memerlukan waktu sehingga diperlukan suatu perencanaan kebutuhan manpower untuk reparasi kapal. Harus dilakukan analisis terhadap banyaknya manpower yang dibutuhkan dan menghitung penambahan biaya dengan digunakannya metode crashing. Dari hasil perhitungan biaya manpower untuk pekerjaan di replating pada proyek reparasi kapal KMP. Jatra III, di dapatkan jumlah manpower saat kondisi normal adalah 10 orang dan setelah menggunakan metode crashing memerlukan manpower 14 orang dengan total selisih biaya pada durasi normal dengan durasi crashing yaitu Rp.480.000,- Dengan demikian presentase kenaikan biaya manpower akibat adanya penambahan tenaga kerja adalah 1,8 % dari biaya normal yang di perlukan. Kata Kunci : manpower, crashing, replating, kapal.

Abstract

This research develops and tests a digital twin (DT)-based smart aquaculture system for mud-free eel farming through the integration of IoT sensing, artificial intelligence (AI)-based prediction, edge computing, and solar energy-based automation. The approach used is experimental systems engineering, which includes system design, hardware and software implementation, virtual replication, and physical-digital two-way synchronization. The system utilizes ESP32-based pH, temperature, dissolved oxygen (DO), ammonia (NH₃), and turbidity sensors, MQTT communication, and Raspberry Pi edge computing. Water quality prediction is performed using long short-term memory (LSTM) and random forest regression. The dataset consists of 30 days of real-time data covering water quality, actuator activity (aerator, pump, feeder), and energy production and consumption by IoT sensors and energy meters. Results show that LSTM excels by R² = 0.94; RMSE = 0.14; MAPE <5% and synchronization latency <1.5 seconds. Solar energy integration reduces energy consumption by 54 67%, whilst automation increases eel survival rate by 78% to 91%. The novelty of this research lies in the first integrated implementation of DT, AIoT, and solar energy-based automation in mud-free eel farming. The proposed framework provides a precise, scalable, and sustainable solution for the development of modern aquaculture.

Abstract

The study in this article is the digitization of ports in supporting agro-industrial logistics in Lampung Province. In writing this article, the research method used is the study of literature and secondary sources through a qualitative approach. Multi-modal transportation means that logistics in Lampung Province involves more than one type or mode of transportation. Data from the Ministry of Industry noted that Indonesia's logistics costs reached 24 percent of GDP. High logistics costs make Indonesia's Logistic Performance Index (LPI) rank low, at 46 in 2018. Indonesia is still losing to Malaysia at 41, Vietnam at 39, Thailand at 32, and Singapore at 7. Utilizing information technology, logistics can be accomplished. So it is hoped that with digitization, the delivery time of agro-industrial products and the costs incurred will be more efficient. The conclusion obtained is that the long waiting time experienced by agro-industry entrepreneurs when shipping goods through the port to the destination area can be reduced, one of which is through digitizing the port by utilizing information technology. Through port digitization, it is hoped that it will reduce dwell time and realize logistics connectivity through the development of multimodal logistics access (land and sea).

Abstract

Perawatan terhadap mesin dan peralatan merupakan keharusan bagi perusahaan yang bergerak dibidang pertanian dan perkebunan. Traktor merupakan salah satu mesin industry pertanian yang digunakan untuk pengolahan tanah, penanaman, pemupukan hingga pemanenan. Traktor jenis ford 6640-4 WD merupakan mesin pertanian yang digunakan untuk aktivitas tersebut. Perawatan terhadap traktor jenis ini dilakukan oleh teknisi yang telah mendapatkan pelatihan dan bekerja sesuai standar operasional prosedur yang ditetapkan. Dalam pelaksanaannya masih banyak ditemukan traktor yang mengalami kerusakan karena kurang baiknya perawatan yang dilakukan oleh teknisi. Berdasarkan data yang diperoleh dari bulan Januari sampai Maret 2022 telah terjadi sejumlah kerusakan yang menyebabkan tidak tercapainya kegiatan pengolahan lahan, penanaman dan pemupukan. Oleh karena itu perlu dilakukan penilaian terhadap perawatan yang dilakukan dengan melakukan integrasi six big losses dan metode overall equipment effectiveness terhadap traktor ford 6640-4 WD yang digunakan. Berdasarkan perhitungan diperoleh hasil Overall Equipment Effectiveness adalah sebesar 29%. Hal ini disebabkan karena tidak adanya nilai yang mencapai standar. Pada kinerja mesin traktor selama 3 bulan yaitu januari sampai dengan maret 2022 nilai avability rate 32.82%, performance rate 133.97%, quality rate 66%. Sedangkan dua losses terbesar penyebab turunnya kinerja mesin sehingga nilai OEE tidak mencapai standar tersebut adalah reduced speed losses sebesar 55% dan equipment speed losses sebesar 42% nilai tersebut setengah dari kerugian.

Abstract

Crackers made from wheat flour and processed fish have become a popular snack among Indonesian consumers. Mrs. Ratih Wardani, owner of Ummi Kemplang Crackers MSME located on Jalan Gatot Subroto, Gang Serasan 1, Bumi Raya Village, Bumi Waras District, Bandar Lampung City, encounters significant obstacles in marketing her products. Narrow market reach hinders business expansion. MSMEs play a vital role in Indonesia's economic development by utilizing local resources. However, digital transformation has become an urgent necessity to expand market reach, accompanied by improved financial management. This community service program aims to enhance production capacity and marketing strategies. Production process modernization is expected to boost the economic welfare of business partners. Marketing improvements were achieved through developing an online sales website that reaches local, national, and international markets. The provision of mixing and cutting machines successfully increased production capacity by 30% while opening opportunities for product diversification.

Abstract

Limited equipment and limited skills are hindering the promotion of the Kesuma Bangsa Herbal Garden Agrotourism. Lack of knowledge of modern production techniques and efficient practices leads to low capacity. Furthermore, inconsistent quality is a challenge due to inefficient introduction and marketing. The lack of a clear and measurable business plan, particularly in terms of manual financial record-keeping, poses a risk of errors in cash management, which ultimately negatively impacts business sustainability. Limited knowledge of marketing and promotion, limited access to markets and distribution networks, and less than optimal use of digital marketing methods. Consequently, the Kesuma Bangsa Herbal Garden Agrotourism market access is limited. Through this community service, the Kesuma Bangsa Herbal Garden Agrotourism market will be expanded not only locally but also nationally. The Kesuma Bangsa Herbal Garden Agrotourism still faces limitations in digital marketing, particularly in understanding information technology that can be used to improve its business. This limitation impacts partners' lack of digital marketing skills. The Kesuma Bangsa Herbal Garden Agrotourism product lacks a clear branding strategy to differentiate its products in the market. This makes it difficult for the business to grow and compete, especially with other MSMEs that already have their own unique offerings. The problem formulation must be stated concretely and clearly in the introduction. Explain the objectives to be achieved through the community service activities with measurable and realistic targets. Also outline the expected benefits of the community service activities for both the target audience and the development of knowledge.
