Abstract

One of the post-harvest honey processing processes is the pasteurization process. Pasteurization is the initial stage of honey processing before evaporation. The high demand for honey in Indonesia requires that honey producing companies must use pasteurization tools with large capacities and do not damage the honey content. Honey will be damaged if the pasteurization temperature is more than 70oC. In addition, the pasteurization process is also still a problem in the honey industry. Therefore it is necessary to make pasteurization tools with automatic and fast temperature control in the pasteurization process. The purpose of this study was to observe the rate of heat penetration into pasteurized honey material and the amount of honey weight pasteurized, then also measured changes in water content, viscosity, degree Brix, and density of density. From the results of measurements of heat penetration rates in pasteurization and conventional pasteurization devices, the difference in time duration on stoves 1, 2, and 3 to increase the initial temperature of 35 oC to 65oC respectively were 45, 45, and 42 minutes with a total of 101 honey, 22 kg while in conventional equipment takes 50 minutes to heat honey as much as 46,780 kg. Gas consumption on stove 1 was 0.291 g/(kgoC), stove 2 was 0.281 g/(kgoC), stove 3 was 0.285 g / (kgoC), whereas gas consumption on conventional stove was 0.272 g/(kgoC). The results of measurements of water content, viscosity, Brix, and density of density before and after pasteurization were as follows 21.99%, 4.835 poise, 63 obrix, 1.356 kg/m3, and 19.82%, 5.453 poise, 64 obrix, 1.358 kg/m3.

Abstract

Masyarakat Desa Pugeran, Kabupaten Mojokerto memiliki masalah pada sampah. Salah satunya adalah limbah kulit bawang yang belum dimanfaatkan oleh masyarakat. Berdasarkan hasil penelitian terdahulu diketahui bawang merah dan bawang putih memiliki kandungan senyawa yang sangat bermanfaat bagi pertumbuhan tanaman begitupun kulitnya. Limbah kulit bawang dapat dimanfaatkan sebagai POC dan pestisida. Kegiatan Pengabdian Kepada Masyarakat (PKM) ini bertujuan untuk memberikan pengetahuan kepada masyarakat dalam pemanfaatan limbah bawang sebagai POC dan pestisida untuk tanaman. Metode pelaksanaan kegiatan dilakukan dengan cara observasi lapangan dan pengumpulan data dengan menggunakan metode rekayasa sosial untuk memperoleh data dari target sasaran yaitu para petani di Desa Pugeran. Kegiatan PKM terdiri atas tahap analisis situasi sampai pendampingan pembuatannya. Dengan adanya kegiatan ini diharapkan masyarakat dapat membuat POC, pestisida dan pupuk kompos dari limbah kulit bawang secara berkelanjutan karena jauh lebih aman, lebih terjangkau, alat dan bahannya juga mudah ditemukan.

Abstract

This study aims to examine the effect of varying percentages of coconut shell charcoal mixed with coal on the physical properties and combustion rate of biocoal briquettes. The briquettes were made with four variations of coconut shell charcoal percentages: 16%, 31.9%, 47.7%, and 63.7%. The results revealed that briquette density tended to decrease with an increasing percentage of coconut shell charcoal, except for the 63.7% mixture, which showed an anomaly with higher density. Mechanical strength, including tensile and compressive strength, decreased as biomass increased due to the weaker mechanical properties of coconut shell charcoal compared to coal. The combustion rate decreased with higher biomass percentages, with longer combustion times for higher biomass content due to the higher calorific value of coconut shell charcoal. Biocoal briquettes demonstrated better combustion efficiency than regular briquettes but were still inferior to super briquettes and pure coal briquettes. This study highlights the potential of biomass-coal mixtures as an alternative, environmentally friendly, and efficient energy source. Keywords: Biocoal Briquettes, Coal, Coconut Shell Charcoal, Combustion Rate. Density.
