Abstract

A micro-hydropower plant is a small-scale power plant that uses water as its propulsion and the prime mover is a turbine. This generating system is very appropriate to be used in rural areas because this system is easy to manufacture, produces a large amount of electrical power, and is relatively inexpensive to manufacture. Based on the above, it is necessary to design a turbine that supports this generating system, including the Cross-Flow Turbine. To design a water turbine so that there are no errors in the design (such as the cost of making it), then a design is carried out. A cross-flow turbine design is designed with a flow rate (Q) = 1.2 m3/s, head (H) = 17 m with an efficiency of 0.75. The main technical specifications from the results of the turbine design are runner diameter (D) = 510 mm, turbine shaft rotation 471 rpm with a specific speed of 61.33 rpm, water power of 200,124 kW, and producing electric power of 100.86kW.

Abstract

In this work, we propose the use of a low-cost PV monitoring system for providing accurate and comprehensive data required in the development of efficient and reliable solar PV plants. The system is developed based on an open-source Arduino platform with the capability to monitor solar irradiance, and electric outputs and temperature of multiple solar panels, which should enable the accurate assessment of solar energy resource, as well as electrical energy produced by PV plant under real operating conditions. To demonstrate its applicability, the system has been installed at the campus of Politeknik Negeri Pontianak in Pontianak City, and the data collected by the system is used to assess solar energy resource at the location. Data collected by the system from August 2020 to September 2021 shows that the values of solar irradiation are in the range of 2.9–4.1 kWh/m2 per day, and electric energy produced by commercial solar panels are in the range of 0.30–0.46 kWh/m2 per day, correspond to the monthly averaged efficiencies of 8–13%. The values of solar irradiation are 15–40 % lower than those obtained from the space-averaged satellite data which are in the range of 4.1–5.8 kWh/m2 per day. This shows the significant effects of local conditions, and confirms the advantage of assessment using the low-cost monitoring system that directly accounts for the effects of local conditions without the need of simulation using complex model and sophisticated software that required in the assessment using satellite-derived data.

Abstract

Menurut Badan Pusat Statistik Kabupaten Kubu Raya yang dituangkan dalam Statistik Pertanian Tanaman Pangan Tahun 2015, area ladang sawah memiliki luas total 52.679 Ha di tahun 2015 yang tersebar di sembilan kecamatan. Salah satunya terdapat di Desa Teluk Nibung, Kecamatan Batu Ampar Luas lahan 25 ha dengan kapasitas produksi 40-50 ton/ tahun dalam satu kali produksi. Selama ini kegiatan Kelompok Tani Nibung Mandiri 2 masih terlalu konvensional, sehingga produksi padi yang dihasilkan pun masih tergolong sedikit. Itu dikernakan masih belum terjangkaunya peralatan pendukung untuk pengolahan dan proses pasca panen di Kelompok Tani Nibung Mandiri 2. Dengan adanya alat bantu untuk proses awal penanaman sampai dengan pasca panen tentunya memberikan harapan bagi Kelompok Tani Nibung Mandiri 2 untuk dapat mempersingkat waktu penanaman padi sehingga dapat meningkatkan produktifitas pada Kelompok Tani Nibung Mandiri 2. Penerapan Ipteks pada “Kelompok Tani Nibung Mandiri 2” ini adalah dengan memberikan bantuan berupa alat traktor dan mesin tebas untuk dapat mempersingkat waktu penanaman padi sehingga dapat meningkatkan produktifitas pada Kelompok Tani Nibung Mandiri 2.

Abstract

Kalimantan Barat merupakan salah satu provinsi di Indonesia yang memiliki potensi industri unggulan menurut Perda No.7 2017 salah satunya ialah pengolahan hasil laut dan perikanan. Hal ini juga diperkuat dengan data BPS tahun 2021 bahwa nilai tangkap perikanan laut mencapai 162.128 Ton dan perikanan darat mencapai 33.365 Ton. Untuk itu banyak kelompok masyarakat yang membuat budidaya ikan dengan memanfaatkan kolam terpal bioflok baik berbentuk kotak maupun berbentuk bulat. Ada beberapa faktor yang mempengaruhi tingkat keberhasilan panen ikan diantaranya kualitas pakan dan kualitas air. Maka dari itu diperlukan penerapan teknologi yang bisa meningkatkan oksigen terlarut didalam air dengan memanfaatkan ilmu mekanika fluida berupa Micro Bubble Generator untuk membuat gelembung mikro yang dapat meningkatkan oksigen terlarut didalam air. Selain itu gelembung mikro juga bermanfaat menjaga kualitas air. Penerapan sistem ini diharapkan dapat meminimalisir kematian awal bibit ikan, mempercepat proses pertumbuhan ikan sehingga dapat memenuhi kebuutuhan permintaan ikan dalam kota dan meningkatkan kesejateraan pelaku pembudidaya ikan.

Abstract

To facilitate students' understanding of the types of water turbines, how they work, and the parameters that affect the performance of water turbines, it will be easier if the water turbine is made on a laboratory scale so that students can observe directly and students can change some parameters directly so that students understand the parameters that affect the performance of water turbines. In this research, a laboratory-scale screw turbine type water turbine will be made equipped with a data acquisition system where several sensors will be installed to read the parameters when the turbine is operating which then all parameters will be displayed on the LCD and recorded into memory automatically. This research was conducted using experimental methods by designing and manufacturing screw turbines using 3D Printing using digital prototyping techniques and designing a data acquisition system to facilitate parameter measurement. The results of the study obtained a screw turbine model with an outer diameter (Ro) of 0.07 m, an inner diameter (Ri) of 0.03 m, a pitch distance of 0.05 m, a thread length of 0.6 m, a maximum output power of 3.5 W at a discharge of 0.07 m3/s, maximum efficiency of 6 % at a discharge of 0.07 m3/s.
