Abstract

The Helical Type H-rotor turbine is a modification of the Darrieus turbine by Alexander Gorlov to improve the design of the H-Darrieus so the turbine can self-starting in low wind speed conditions. The purpose of this study is to analyze the pitch angle (5°, 0°, and -5°) when using the symmetrical airfoil (NACA 0018) on the performance of coefficient of power (CP), tip speed ratio (TSR) and coefficient of torque (CT) produced by Helical Type H-rotor turbine. The method used in this research is experimental investigation using wind tunnel.  The Helical Type H-rotor wind turbine is subjected to wind speed of 6 m/s. The results obtained show that the use of 0° pitch angle produces better CP, TSR and CT values than other pitch angles due to the angle of attack produced. this is due to the 0° pitch angle produces an angle of attack that is able to make a more optimal lift force on the turbine blade. At 0° pitch angle the CP value is 0.0337, TSR value is 1.5073 and CT value is 0.0224. While wind turbine that use -5° pitch angle produce better performance than wind turbine that use 5° pitch angle. However, the performance value of both (-5° and 5° pitch angle) is still below the wind turbine with 0° pitch angle.

Abstract

Hydropower is energy obtained from flowingwater and can be used for mechanical energy or electricalenergy. Electrical energy is energy that is used to fulfill humanneeds in life. The need for electrical energy in Indonesiacontinues to increase by an average of 3.9% from year to yearuntil 2050. There are various water sources in Kalimantansuch as water ditches, as well as reservoirs that have low-speedwater flow and the capacity to accommodate water levels thatare not too high. The Savonius water turbine can be utilized inthese conditions because it has the advantage of a simpleturbine construction, and is suitable for relatively low velocitywater flows. This study analyzes how well the Savonius waterturbine is by applying different deflector shapes. The methodapplied in this experiment is an experimental study using aSavonius turbine. The conclusion in this study is that applyinga deflector will improve turbine performance much better thannot using a deflector. Experiments by applying deflectors,namely convex deflectors, flat deflectors, and concavedeflectors, it was concluded that the application using aconcave deflector resulted in the highest rotational speedproduced by the turbine, the maximum value of turbine powerand the Savonius turbine coefficient of 206.3 rpm, 0.196 Wattand Cp = 0.124.

Abstract

Turbin angin sumbu vertikal (TASV) mempunyai kelebihan antara lain konstruksi yang tidak rumit, dapat menerima angin dari segala arah dan mempunyai perawatan yang mudah namun juga mempunyai kekurangan yaitu self starting dan performa yang sangat rendah. Agar mendapatkan performa yang baik diperlukan inovasi dalam mengembangkan proses konversi energi kinetik angin menjadi energi listrik. Salah satu Upaya yang dapat dilakukan adalah merancang generator listrik. Penelitian ini bertujuan untuk merancang generator tipe Axial Flux Permanent Magnet (AFPM) yang digunakan untuk membangkitkan tenaga listrik pada turbin angin sumbu vertikal tipe Ugrinsky. AFPMG didesain untuk daya turbin sebesar 0,227 Watt dimana turbin angin Ugrinsky tersebut mempunyai luas 0.16 m2 dengan kecepatan angin yang digunakan adalah 2 m/s. Berdasarkan desain turbin angin tersebut menghasilkan nilai indikator perancangan AFPMG yaitu 270 jumlah lilitan, 9 kumparan, jumlah magnet 12 buah dan merupakan generator 3 phasa.

Abstract

Kampung Nelayan merupakan sebuah kampung yang berada di sekitar kawasan Pantai Cemara Kelurahan Manggar Baru, Kecamatan Balikpapan Timur. Pantai Cemara merupakan salah satu destinasi wisata di Balikpapan yang mempunyai keunikan yaitu di sekeliling Pantai tumbuh pohon Cemara. Sebagai salah satu program yang dapat digunkanan untuk meningkatkan penghijauan dan menarik wisatawan yaitu pertanian hidroponik. Selain itu pertanian Hidroponik juga dapat digunakan oleh warga sebagai alternatif penggunaan sayuran untuk konsumsi pribadi. Kegiatan pendampingan program penghijauan yang dilaksanakan di Kampung Nelayan Balikpapan dibagi kedalam tiga tahapan. Tahap pertama yaitu pelatihan untuk meningkatkan pemahaman mengenai pertanian hidroponik. Tahap kedua adalah pembuatan rangkaian hidroponik. Tahap ketiga adalah implementasi atau instalasi hidroponik di Pantai Cemara. Sebagai hasil dari kegiatan yaitu warga dapat secara mandiri mengembangkan pertanian hidropinik.

Abstract

The processing and marketing group (Poklahsar) Swakarya Bersama is one of the women's MSMEs located in Penajam Paser Utara (PPU) Regency. Poklahsar Swakarya Bersama is an MSME that drives regional superior products, namely processed seaweed. One of the superior products is seaweed tortilla chips which have been produced since 2019. The most important part in the production process of seaweed tortilla chips is drying. The drying process influences product quality, namely crispness, durability (shelf life) and aroma. The drying carried out by Poklahsar Swakarya Bersama still uses direct drying by the sun. The aim of the activities carried out is to implement a simple drying house which can improve product quality and shorten production time. The advantage of the simple designed drying house is that the heat produced comes from sunlight and does not require additional heat generating equipment. The equipment test results show that a simple drying house produces a faster drying rate compared to traditional drying. The drying rate of tortilla chip dough using a greenhouse effect dryer was 63.33 grams/hour. A simple drying house can also protect products from exposure to unfavorable environments so that the resulting products are cleaner and of better quality.

Abstract

Vocational high school (SMK) students represent a level of vocational secondary education expected to fulfill the demand for technical labor at specific levels within the industry. However, current SMK graduates face challenges due to intense competition in securing employment. This community service initiative aims to enhance the skills of SMK students by focusing on the utilization of Information and Communication Technology (ICT) in the preparation of post-graduation documents. A case study was conducted at a private vocational high school (SMKS) in and state vocational high school (SMKN) in Tanah Bumbu Regency as an effort to prepare students to face the challenges of Industry 4.0. Through outreach activities, this initiative introduced the concept of community service and the benefits of ICT in document preparation. The methods employed aimed to achieve outcomes such as improving students' skills, applying ICT in preparing supporting documents for job applications, and enhancing students' competitiveness in the labor market. The results of the activities carried out showed an increase in participants' knowledge of curriculum vitae and job application letters. Survey results also indicated that the seminar was highly beneficial for participants in this community service activity through technical outreach.
