Abstract

This study aims to explain the characteristics of government policies in Sungai Gelam District, Muaro Jambi Regency. The research method used is empirical juridical and the procedure for sampling is done by purposive sampling. The results showed that. The role of the camat in the fostering and supervision of village administration in Sungai Gelam Sub-district is based on Article 21 of Government Regulation No. 19/2008 concerning Kecamatan. The sub-district government has a strategy in fostering and overseeing village administration through the mapping of regions or villages that are experiencing difficulties in administering village government administration. Basically, the sub-district government has provided guidance and supervision to the village government, but the details are not included in the work program. This was proven in every 6 months the village government was asked to evaluate the performance so that there were no mistakes. Then always fostering village officials with a pattern when village officials have problems in the field always consult with the head of government. Camat supervision and supervision programs always carry out evaluations in matters of village government administration. So, the implementation of the program is not detailed, but carried out in accordance with the needs that exist in the village government. One of the obstacles to the guidance and supervision of village administration is to improve the ability and inadequate human resources and the lack of staff who have expertise.

Abstract

Studi ini meneliti dampak penggunaan bahan bakar alternatif terhadap emisi kendaraan roda dua, karena peningkatan jumlah kendaraan di Indonesia yang berkontribusi terhadap polusi udara. Penelitian ini membandingkan emisi Honda Vario 110 PGM-FI yang menggunakan bahan bakar pertalite dan LPG. Penelitian ini menggunakan eksperimen statistik deskriptif dua tahap. Hasilnya menunjukkan bahwa penggunaan gas LPG mengurangi emisi secara signifikan. Emisi CO dan CO2 tidak terdeteksi saat menggunakan LPG, sedangkan penggunaan pertalite menghasilkan rata-rata emisi CO 0,14% dan CO2 1,13%. Emisi HC untuk LPG sedikit lebih tinggi (46,33 ppm) dibandingkan pertalite (41,33 ppm). Kesimpulannya, LPG menunjukkan potensi besar dalam mengurangi emisi gas berbahaya pada sepeda motor, membuka peluang untuk pengembangan transportasi yang lebih berkelanjutan dan ramah lingkungan. This study investigates the impact of using alternative fuels on emissions from two-wheeled vehicles, prompted by the increasing number of vehicles in Indonesia that contribute to air pollution. The aim of this research is to compare the emissions from the use of pertalite and LPG fuels in the Honda Vario 110 FI. The method employed in this study is an experimental approach, analyzing data using descriptive statistics in two stages. The results indicate that using LPG significantly reduces emissions. CO and CO2 emissions were not detected when using LPG, whereas using pertalite resulted in average emissions of 0.14% CO and 1.13% CO2. The HC emissions for LPG were slightly higher (46.33 ppm) compared to pertalite (41.33 ppm). In conclusion, LPG demonstrates significant potential in reducing harmful gas emissions from motorcycles, offering opportunities for developing more sustainable and environmentally friendly transportation.

Abstract

Sepeda motor matic injeksi telah menjadi pilihan populer di Indonesia, namun performa mesinnya dapat menurun seiring waktu, terutama pada kondisi sistem Continuous Variable Transmission (CVT). Penelitian ini bertujuan menganalisis pengaruh penggunaan roller tipe sliding dan modifikasi drive pulley terhadap daya dan torsi. Menggunakan metode eksperimen dengan objek Honda Beat FI 2016, hasil menunjukkan roller tipe sliding dengan drive pulley standar menghasilkan performa terbaik, dengan rerata daya 5,04 kW dan torsi 7,06 Nm. Kombinasi roller tipe sliding dengan drive pulley modifikasi menunjukkan puncak daya 5,95 kW dan torsi 9,43 Nm, meskipun rerata terendah. Disimpulkan modifikasi sistem CVT dapat meningkatkan performa, namun memerlukan optimasi cermat untuk menyeimbangkan performa puncak dan konsistensi. Penelitian ini memberikan wawasan berharga bagi pengembangan sistem CVT pada sepeda motor matic injeksi. Fuel-injected automatic motorcycles have become a popular choice in Indonesia, but their engine performance can decline over time, mainly due to the condition of the Continuous Variable Transmission (CVT) system. This study aims to analyze the effect of using sliding-type rollers and modifying the drive pulley on power and torque in fuel-injected automatic motorcycles. Using an experimental method with the Honda Beat FI 2016 as the research object, the results show that sliding-type rollers with a standard drive pulley produced the best overall performance, with an average power of 5.04 kW and an average torque of 7.06 Nm. The combination of sliding-type rollers with a modified drive pulley showed a peak power of 5.95 kW and a peak torque of 9.43 Nm, although with the lowest average. It was concluded that modifications to the CVT system can improve engine performance, but require careful optimization to balance peak performance and consistency. This research provides valuable insights for the development of the CVT system in fuel-injected automatic motorcycles.
