Kota Jayapura banyak memiliki lokasi wisata pantai yang indah dan banyak dikunjungi pengujung baik dari pengunjunga lokal, pendatang dan pengunjung asing. Pantai Hamadi yang indah sering dikunjunggi masyarakat kota jayapura dan pengunjung asing yang berwisata karena letaknya sangat strategis, namun di balik keindahan Pantai Hamadi ada pemandangan yang kurang menarik yaitu terdapat banyak sampah-sampah plastik dan berbagai jenis sampah lainnya yang berserakan di pinggiran bibir pantai dan dibawah pepohonan bahkan sampai di pingiran jalan dan dibawah hutan manggrov. Tujuan kegiatan memberikan sosialisasi serta pendampingan kepada pengelola dan pengunjung pantai dalam meningkatkan kepedulian dan menjaga lingkungan di pesisir pantai hamadi serta pengelolaan limbah plastik menjadi barang yang mempunyai nilai ekonomis dan memberikan kenyamanan bagi pengunjung pantai. Tim pengabdian kepada masyarakat USTJ mendampingi pihak pengelola yang berusaha di pantai hamadi dalam sosialisasi untuk memberikan pengarahan dan penataan lokasi pantai dengan melibatkan dosen dan mahasiswa. Kegiatan desain, pengembangan dan perancangan tempat sampah plastik dan pemanfaatan limbah plastik menjadi sesuatu yang bermanfaat seperti tempat duduk (ecorbrick) serta papan informasi sosialisai kepada pengelola dan pengunjung pantai dilakukan selama (satu bulan) dengan materi penguatan pengetahuan dan pemahaman terhadap pentingnya pantai bersih dari sampah plastik.

Experimental research has been conducted on the effect of ignition timings on the characteristics and performance of gasohol engines such as power, torque, specific fuel consumption, and thermal efficiency. The fuel used in this research is pure gasoline and a mixture of 50% bioethanol (BE50). The results show that the ignition timing that gives the maximum effect occurs at the top and bottom dead points of 9 degrees for gasoline and 12 degrees for BE50 fuel. Furthermore, the maximum power is obtained at 6,500 rpm, and at an ignition time of 12 degrees BTDC the maximum power generated is 4.63 hp, while for an ignition time of 9 degrees BTDC the power generated is 3.38 hp which occurs at 6500 rpm. These results indicate that there is an increase in power of 6.4%. Moreover, the results also show that for optimal gasoline conditions, the amount of energy consumed at an engine speed of 7000 rpm is around 15705.78 kcal/hour, and for BE-50 it is around 12582.03 kcal/hour, where there is a reduction of about 25.44 %. However, in general, it can be seen that during optimal ignition, there is a saving in fuel consumption in the gasoline-BE50 mixture, while at the same time producing a fairly large thermal efficiency. These results indicate that BE50 has the potential to be used as an alternative fuel in small gasoline engines.

The burning rate of coconut oil droplets has been investigated experimentally by adding bio-additives of clove oil and eucalyptus oil. Tests were carried out with single droplets suspended on thermocouples at room atmospheric pressure, and room temperature and ignited with a hot wire. The addition of clove oil and eucalyptus oil as bio-additives into coconut oil was 100 ppm and 300 ppm, respectively. The droplet combustion method was chosen to increase the contact area between the air and fuel so that the reactivity of the fuel molecules increases. The results showed that the eugenol compounds contained in clove oil and cineol compounds in eucalyptus oil were both aromatic, and had an unsymmetrical carbon chain geometry structure. Furthermore, this factor can potentially accelerate the occurrence of effective collisions between fuel molecules. Therefore the fuel is combustible, as evidenced by the increased burning rate, where the results show that without bio-additives, the burning rate of crude coconut oil (CCO) is about 0.7 seconds. These results are 0.15 to 0.2 seconds slower than CCO with bio-additive, which is around 0.55 to 0.6 seconds. Moreover, from the observations, it was found that the highest burning rate was achieved in both bio-additives with a concentration of 300 ppm.

Penelitian ini menggunakan empat stasiun penelitian. Hasil penelitian menunjukkan bahwa air sumur di semua stasiun penelitian terdapat Escherichia coli, stasiun 2 dan 3 tingkat kekeruhan dan kandungan besi (Fe) tidak memenuhi baku mutu air bersih yang hygiene sanitasi. Pada stasiun 2 dan 3 diperoleh indeks pencemaran berturut-turut sebesar 2,01 dan 2,68 yang mana kualitas airnya tergolong tercemar ringan, sedangkan pada stasiun 1 dan 4 berturut-turut diperoleh indeks pencemaran sebesar 0,67 dan 0,69 kualitasnya tergolong memenuhi baku mutu.

A novel approach was employed to develop alternative fuels by blending pyro-oil from used plastic with graphene, which acted as a combustion additive. The biofuels were produced through pyrolysis of high-density polyethylene (HDPE). When evaluating the fuel blends, the fuel properties were analyzed and compared to commercially available diesel fuel, while Fourier transform infrared (FTIR) spectrometry was employed to know the fuel character. The findings demonstrate that including graphene as a combustion additive significantly enhances the Fuel's performance. The phenomena suggest that graphene effectively weakens the dispersion forces among the triglyceride molecules. Consequently, the droplet is easier to burn. By incorporating graphene, the alternative fuels droplet exhibits improved ignition properties, offering potential benefits in terms of efficiency and performance. The additive plays a crucial part in modifying the molecular structure of the Fuel, resulting in enhanced reactivity and ignition characteristics. Furthermore, the analysis of physical properties and spectroscopic data provides valuable insights into alternative fuels' molecular composition and behavior.

Experimental investigations were conducted to assess the impact of an adjuster on the heating efficiency and flame stability of sago waste briquettes. The adjuster was introduced to maintain a consistent burning distance, thereby enhancing the combustion heat of the fuel. Infrared thermometry was employed to monitor the temperature evolution within the briquette and the combustion load, represented by water in a pan. The findings demonstrate that adding an effective adjuster significantly improves the performance of both the briquettes and the stove, resulting in enhanced effectiveness and efficiency. This is evident from the observed increase in combustion temperature and faster boiling time of the water. The consistent burning distance ensures a stable and uniform heat supply to the briquettes, facilitating more efficient fuel utilization as all parts of the fuel can undergo complete combustion and transfer heat to the pan. Molecular analysis reveals that the stability of the burning distance weakens the Van der Waals bonds within the carbon chain, thereby increasing the reactivity of the fuel molecules. Consequently, the fuel exhibits improved heat absorption capability and becomes highly combustible.

This research aims to determine the performance of the Internal Combustion Engine Type T113D on carbon monoxide (CO) and hydrocarbon (HC) exhaust emissions, engine efficiency and rotation, to obtain efficient CO and HC. The research process was carried out by: testing rotation variations of motor power, torque, thermal efficiency, average effective direct fuel consumption, carbon monoxide and hydrocarbons. The research results showed that at 1000 rpm the highest CO was 10.00% and the lowest CO at 3000 rpm was 8.59%. What then influences the increase and decrease in CO is the reduction in fuel and air which is less homogeneous or does not burn completely in the combustion chamber. So it makes CO become high. High carbon monoxide is influenced by a poor mixture of air and fuel so that it can affect combustion in the combustion chamber, causing low engine speed. The lower the rotation, the higher the hydrocarbons (HC), this is because the mixture of air and fuel is less homogeneous which can affect the level of hydrocarbons.

Pharaa Market is the main market in Hinekombe Village, Sentani District, Jayapura Regency. High market activity has a direct impact on the production of quite a lot of waste, and if it is not handled well, it has the potential to make Pharaa Market a dirty place and reduce consumers' interest in shopping. This will hinder the circulation of the economy and people's income. Therefore, the aim of this community service activity is to increase the village community's understanding and skills in utilizing waste to create organic fertilizer. The methods used are socialization and training. The results obtained indicate that the community has gained a new perspective on the potential of waste and has developed excellent skills in managing waste to produce organic fertilizer.
