Indonesia has the potential to produce large amounts of electrical energy by utilizing sustainable energy, especially water energy. There are still many areas that are far from urban areas that do not have electricity, especially remote areas. One of them is Nagari Koto Hilalang, Solok Regency, which has built a Micro Hydro Power Plant (PLTMH). The purpose of this research was to determine the capacity and potential of PLTMH in Nagari through simulation. This research uses the Computational Fluid Dynamics (CFD) simulation method with the Ansys Fluent 2021 R2 Student Version software. The magnitude velocity simulation values for the inlet velocity 12.44 m/s, 13.28 m/s, and 13.65 m/s produce different maximum values for the runner. The resulting torque has a value of 110.5 Nm. The exact output power generated by the Ansys simulation has a value of 10.78 kW. The efficiency of the turbine with a power of 10.78 kW obtained from the simulation results is 66%.

One of the biomass potentials that can be utilized is felled wood waste which can be used as an energy source. The advantage of biomass is that it can be renewed so that it triggers a sustainable energy source. Biomass energy that will be made into briquettes is processed and compressed so that the shape is more regular and has a high calorific value. In this study, wood waste will be used as a source of biomass. The test was carried out, namely the thermogravimetric test to determine the proximate content. The method used is using Sengon wood as a raw material with a particle size exceeding 18 mesh but not exceeding 30 mesh. Briquetting using a hydraulic pump and briquette hot molding, temperature variations of 250℃, 300℃, and 330℃ with a time of 10 minutes. The test was carried out, namely the thermogravimetric test to determine the proximate content of the briquettes. Applying pressure to the briquettes while simultaneously heating makes the briquettes strong. From 3 variations of temperature treatment, it was found that the temperature of 330℃ had a high carbon content and low volatility of all test samples.

A container yard is a place for storing containers, a place for cleaning, and repairs, as well as a place for carrying out container surveys. Currently planning the construction of a container yard in Eastern Indonesia is being carried out. In its construction, a container yard requires large investment costs due to many factors such as the difficulty and high cost of transporting raw materials, permits that require planning, to the need for proper business processes in order to provide smooth operational activities by minimizing risk. The purpose of this study is to identify the risks and causes of risks involved in the container depot development project in Eastern Indonesia using the quantitative risk assessment (QRA) method, so as to provide the most influential risk management recommendations. The research succeeded in identifying 24 risks and 24 causes of risk. Furthermore, from the calculation results, it was concluded that there were 9 most influential risks. Depo kontainer merupakan tempat penyimpanan kontainer, tempat pembersihan, perbaikan, serta tempat untuk pelaksanaan survei kontainer. Saat ini sedang dilakukan perencanaan pembangunan depo kontainer di Indonesia Timur. Dalam pembangunanya, depo kontainer membutuhkan biaya investasi yang besar yang disebabkan banyak faktor seperti sulit dan tingginya biaya transportasi bahan baku, perizinan yang membutuhkan perencanaan, hingga kebutuhan akan adanya proses bisnis yang tepat agar dapat memberikan kelancaran pada aktivitas operasional dengan meminimasi risiko. Tujuan penelitian ini adalah mengindenfitikasi risiko dan penyebab risiko yang terdapat pada proyek pembangunan depo kontainer di Indonesia Timur dengan metode quantitative risk assessment (QRA), sehingga dapat memberikan usulan penanganan risiko yang paling berpengaruh. Penelitian berhasil mengidentifikasi 24 risiko dan 24 penyebab risiko. Lebih lanjut dari hasil perhitungan disimpulkan ada 9 risiko paling berpengaruh.

PT. XYZ is a Machining, Fabrication, Automation, Manufacturing (Precision Part, JIG & Fixture) company, Engineering (Design Mechanic, pneumatic, system, Hydraulic System) and maintenance services. Production operators, with limited resources, often carry out large, complex, time-consuming jobs with high demands on quality and accuracy. These conditions make operators often do work that demands more attention in a long period of time, often even working overtime so that work can be completed on the target time. It is feared that what this operator is experiencing will exceed the limits of their workload, especially the amount of mental workload. To analyze this PT. XYZ uses the NASA-TLX (National Aeronautics and Space Administration Task Load Index) method on workers from the production department. The results showed that the mental workload felt by ten workers was included in the high classification with an average WWL value of 76.33. PT. XYZ merupakan perusahaan Machining, Fabrication, Automation, Manufacturing (Precision Part, JIG & Fixture), Engineering (Design Mechanic, pneumatic, system, Hydraulic System) serta jasa maintenance. Operator produksinya, dengan sumber daya yang terbatas, sering melakukan pekerjaan dalam jumlah yang besar, kompleks, waktu yang singkat, serta tuntutan kualitas dan ketelitian yang tinggi. Kondisi tersebut membuat operator sering melakukan pekerjaan yang menuntut perhatian lebih dalam periode waktu yang lama, bahkan sering lembur agar pekerjaan dapat selesai pada terget waktunya. Apa yang dialami operator ini dikhawatirkan akan melebihi batas beban kerjanya, terkhusus besarnya beban kerja mental. Untuk menganalisa hal tersebut PT. XYZ menggunakan metode NASA-TLX (National Aeronautics and Space Administration Task Load Index) pada pekerja dari departemen produksi. Hasil penelitian menunjukkan bahwa beban kerja mental yang dirasakan oleh sepuluh pekerja masuk dalam klasifikasi tinggi dengan nilai WWL rata-rata adalah 76,33.

This study aims to design a cross-flow turbine in a micro hydro power plant as an alternative energy source for Indonesian remote areas that do not have electricity. The research location for the turbine design in this study is in the Ngalau Baribuik, located in Batu Gadang, Lubuk Kilangan district, Padang city. Based on the analysis of water flow characteristics, the type of turbine that is suitable for low water debit and head condition is cross flow turbine. The geometry of the cross-flow turbine is designed by considering the power electricity needs of the community and the electrical potential at the site. This experimental research was carried out in two stages; field investigations related to water flow characteristics and energy need analysis of local communities, the design and manufacture of the turbine. Based on theoretical calculation, the cross-flow turbine can produce up to 5 kW of electrical power which can meet 70% of the community's energy needs. Penelitian ini bertujuan untuk merancang sebuah turbin aliran silang pada Pembangkit Listrik Tenaga Mikro Hidro (PLTMH) sebagai alternatif sumber energi bagi daerah terisolir yang belum teraliri listrik. PLTMH dirancang untuk masyarakat kawasan Ngalau Baribuik yang berlokasi di Batu Gadang Lubuk Kilangan kota Padang. Berdasarkan analisis karakteristik aliran, untuk kondisi debit dan tinggi jatuh air yang kecil turbin yang paling sesuai digunakan adalah aliran silang. Disain dan geometri turbin disesuaikan dengan kebutuhan masyarakat dan potensi yang ada di lokasi. Penelitian eksperimen ini dilaksanakan dalam dua tahap; (a) investigasi lapangan terkait dengan karakteristik aliran air dan kebutuhan energi masyarakat, dan (b) proses perancangan dan pembuatan turbin. Secara teoritis, turbin aliran silang yang dirancang akan dapat memproduksi daya listrik hingga 5 kW yang akan memasok 25% kebutuhan energi masyarakat setempat.
