Abstract

Abstrak: Dinas Lingkungan Hidup (DLH) Balikpapan memperingatkan bahwa kapasitas Tempat Pemrosesan Akhir Sampah (TPAS) Manggar diperkirakan akan mencapai batas maksimal pada tahun 2026 apabila tidak dilakukan upaya pengelolaan yang lebih optimal. Beberapa cara mengkonversi limbah padat menjadi bahan bakar telah dilakukan untuk mengurangi volume sampah padat yang semakin meningkat. Namun, tidak menunjukkan hasil yang signifikan, sehingga upaya pengolahan sampah padat terus dilakukan. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan kemampuan masyarakat, khususnya komunitas pengelola sampah TPAS Manggar, dengan melatih mereka membuat produk biopellet menggunakan mesin pelletizer yang berbasis sistem penggerak roller. Kegiatan pengabdian dilakukan dengan melibatkan 25 peserta dari komunitas pengelola sampah TPAS Maggar. Kegiatan ini mencakup penyampaian materi teori, yang meliputi sosialisasi mengenai sampah padat, pemilahan sampah, dan manajemen pengolahannya. Selain itu, dilakukan demonstrasi penggunaan alat pelletizer, praktik langsung pembuatan biopellet, serta evaluasi melalui pre-test dan post-test. Dengan menggunakan analisis statistik Paired Two Sample for Means, terdapat peningkatan yang signifikan dalam tingkat pengetahuan serta keterampilan anggota kelompok pelatihan. Perbedaan rerata skor pre-test dan post-test yang secara statistik signifikan mengindikasikan bahwa program pelatihan tersebut memiliki dampak yang positif terhadap kemampuan para peserta. Dengan hasil evaluasi ini, pelatihan serupa diharapkan dapat direplikasi di komunitas lain sebagai upaya peningkatan kesadaran lingkungan dan penerapan teknologi ramah lingkungan dalam pengelolaan sampah.Abstract: The Balikpapan Environmental Agency (DLH) has issued a warning that the Manggar Final Waste Processing Site (TPAS) may reach full capacity by 2026 unless more effective waste management strategies are implemented. Although various methods of converting solid waste into fuel have been attempted to address the growing waste volume, these efforts have yet to produce significant results. Consequently, solid waste processing initiatives remain ongoing.In response, a community service program was initiated to enhance the capabilities of local residents, particularly members of the Manggar TPAS waste management team. This initiative focused on training participants in the production of biopellets using a pelletizer machine equipped with a roller drive system. A total of 20 community members took part in this program. The training included the presentation of theoretical material covering topics such as solid waste management, sorting procedures, and waste processing techniques. It also featured hands-on sessions where participants practiced operating the pelletizer and producing biopellets. To assess the program’s effectiveness, participants underwent pre- and post-training evaluations. Using the Paired Two Sample for Means statistical method, the data revealed a significant improvement in the participants’ knowledge and skills. The measurable increase in average test scores demonstrates the positive impact of the training. Based on these findings, it is advisable to implement similar initiatives in other communities to encourage environmental awareness and the use of sustainable waste management technologies.

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.
