Abstract

The prototypes of the Oscillating Water Column (OWC) system constructed by BPPT at Pantai Baron, Gunung Kidul, in 2005  and 2006 were not sustainable. Based on its condition and location, the root cause of the problem was defined. Maximizing the total efficiency and capacity factor (Cf) of the OWC system was the main factor for optimizing energy output. Collecting  factors that constructed the total efficiency and capacity factor of the OWC system was conducted. Selecting the appropriate  turbine, generator, and chamber system led to an increase in the total efficiency of the OWC system. Reducing the effect of  wave diffraction, finding optimum wave data for forecasting, finding optimum water depth area to avoid wave breaking area,  reducing corrosion chance by selecting the optimum height of the OWC system, and using a control system to minimize stalling  on turbine were factors that constructed capacity factor

Abstract

Disposable baby diaper waste causes water and soil pollution when disposed in rivers, drains, streets, ground, and other places. This condition is triggered by the lack of awareness of disposable baby diaper waste management by the community, especially youngmothers who have toddlers. An appropriate solution is needed to overcome this problem and reduce the negative impact on the environment. This activity aims to introduce a waste management approach and determine the impact of the introduction of the approach in overcoming the waste problem at Tanjungrejo Village river, Madiun District, Madiun Regency, East Java Province. The research applied a qualitative method with observation and interview approach. The research sample was selected by using a purposive sampling method. Based on observations, each mother mostly threw two or three disposable baby diapers used by toddlers at landfills. Many mothers still do not know how to reduce the growing amount of disposable baby diaper waste. Media posters,presentation slides, and demonstrations of the process of making pots and ornamental plant media were carried out in the implementation of the socialization on July 2023 at the Tanjungrejo Village Head Office. Through this socialization, all mothers who have been interviewed express interest in trying and practicing the process of disposable baby diaper waste into pots and ornamental plant media. Therefore, this socialization activity can be a breakthrough innovation in the form of utilizing disposable babydiaper waste into pots and ornamental plant media.

Abstract

Bullying in the school environment is an emerging issue that needs to be taken care of by various parties. It will cause a negative impact on the future of both the perpetrator and the victim. Children may grow up with unstable emotions and have low empathy for others. The purpose of this activity is to introduce basic emotions and anti-bullying knowledge as an effort to increase empathetic awareness in the community in preventing bullying. Prospective comparative study with an observation and interview was carried out as the methodology, teachers, and parents. The research sample was selected using a purposive sampling method. Based on observations, it was found that there are behaviors that indicate bullying in the school environment. In addition, students were also found to have poor empathy and emotional management. The activity of introducing basic emotions and anti-bullying behavior utilized posters, mini games, and attaching stickers. This activity is targeted for grade 5 elementary school students because they are already able to recognize their emotions, and their experience will be an example for other students in another grade. Students, teachers, and parents who have been interviewed stated that this emotional recognition and anti-bullying activity was excellent and had a positive impact on children's emotional development. Students increasingly understand the meaning of basic emotions and anti-bullying, recognize self-emotions, know how to express emotions, increase empathy, and create a more comfortable school environment.

Abstract

Sektor transportasi memiliki proporsi konsumsi energi terbesar kedua di Indonesia setelah sektor rumah tangga. Berdasarkan Indonesia Energy Outlook 2017, konsumsi energi sektor transportasi mencapai 31% dari total kebutuhan dan meningkat 5,2% per tahunnya dalam kurun waktu 2010-2015. Yogyakarta sebagai kota pelajar dan tujuan wisata mendorong perbaikan sistem transportasi umum untuk menekan jumlah penggunaan kendaraan pribadi. Kendaraan listrik merupakan salah satu cara mengatasi ketergantungan bahan bakar berbasis minyak bumi sekaligus dapat menjadi solusi transportasi umum ramah lingkungan dan rendah emisi. Analisis konsumsi energi pada bus listrik dilakukan dengan menggunakan bus Trans Jogja jalur 3B untuk mendapatkan parameter berkendara yang sesuai, dari hasil analisis tersebut dapat ditentukan bus yang memerlukan konsumsi energi dan emisi CO2 paling sedikit. Melalui hasil penelitian diperoleh siklus berkendara Trans Jogja jalur 3B memiliki jarak 36.818 m, waktu tempuh 5.391 s, dan rerata kecepatan 24,5 km/jam. Berdasarkan pemodelan perhitungan energi tiap lampu lalu lintas, diperoleh konsumsi energi bus listrik sebesar 1,35 kWh/km sedangkan bus konvensional membutuhkan 2,74 kWh/km. Emisi yang dihasilkan dalam satu siklus berkendara bus listrik berdasarkan pemodelan pasokan energi tahun 2025 dan 2050 adalah sebesar 22,13 kgCO2 dan 19,78 kgCO2 sedangkan pada bus konvensional sebesar 26,94 kgCO2.
