Abstract

This study aims to determine the influence of ambient air temperature which is temperature and RH (relative humidity) in drying process using aeration and condensation method. Aeration method utilized natural air flow from environment to flow hot air from heater chamber to the drying chamber. Condensation method sealed air flow from environment to minimize ambient air temperature and relative humidity inside drying chamber. Parameters observed were evaporated water, drying time, material weight reduced and electrical energy needs. The study showed 12 hours drying process evaporate 1,775 gram water by aeration method while condensation method evaporate 1,788 gram water. Nevertheless to gain 9% water content takes 6 hours 33 minutes by aeration method while condensation method takes 5 hours 33 minutes. It also needs 1.0943KWh electrical energy by aeration method while condensation method needs 1.0159 KWh.  Keywords : chip lenjeran, aeration method, condensation method

Abstract

Penelitian ini dilatarbelakangi kelemahan pembakaran tungku yang menghasilkan pembakaran yang tidak sempurna dikarenakan kurang optimalnya rasio bahan bakar dan udara serta waktu tinggal pembakaran yang singkat. Penelitian ini bertujuan untuk memperoleh laju umpan bahan bakar dan laju aliran udara yang menghasilkan pembakaran sempurna. Makalah ini menjelaskan pengaruh laju umpan bahan bakar dan laju aliran udara terhadap kinerja pembakaran tungku fixed bed sebagai sumber energi panas pengering. Pengukuran efisiensi tungku dilakukan pada berbagai laju umpan sekam dan laju aliran udara. Penelitian ini dilakukan pada 3 laju umpan sekam yaitu 12, 15, dan 18 kg/jam, dan pada 5 laju aliran udara yaitu 86,4; 120,96; 114,84; 108 dan 154,8 kg/jam. Perlakuan optimum diperoleh pada laju umpan sekam 15 kg/jam dan laju aliran udara 114,84 kg/jam dengan efisiensi tungku sebesar 73,99%, panas yang dihasilkan 41,55 kW dan dan % abu/arang yang diproduksi 17,89%. Suhu gas buang bervariasi dari 99,78-474,23°C pada berbagai laju umpan sekam dan laju aliran udara. Analisis gas buang menunjukkan pelepasan panas maksimum terjadi ketika tungku diberi kelebihan udara berlebih 100% yang dibutuhkan untuk pembakaran sempurna.

Abstract

This research was motivated by the use of a fixed bed furnace. Fixed bed furnaces are less effective because their use is fixed.  The purpose of this research was to design a mobile drying furnace fueled by sawdust biomass.  This research uses an experimental method with 3 stages of design, namely design approach, functional design and structural design. The data obtained were analyzed descriptively. The result of this research is a mobile drying furnace designed consisting of a fuel feeder, fuel channel, hopper, combustion chamber and heat exchanger chamber, chimney and furnace outlet channel and channel after the fan that can function properly. Furnace testing was carried out using sawdust fuel. The resulting feed speed is 10.3 kg/hour, the capacity of the combustion chamber for sawdust is 3.4 kg, the average temperature in the fuel feeder is 40.41 °C, in the combustion chamber 414.57 °C, in the heat exchanger 79.80 °C, in the chimney 104.11 °C, in the furnace outlet channel 62.77 °C, in the channel after the fan 46.08 °C, the sawdust fuel consumption rate was 5.8 kg/hour and the furnace efficiency obtained in the study was 53.90%. The resulting hot air temperature can be used for drying grain.Key words:  design, efficiency furnace, mobile drying furnace, temperature

Handoko, W., Rejo, A., & Panggabean, T. (2024). Financial feasibility assessment of hand tractor controlled by android system wifi network based in wetland agroindustry. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 895–905).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The advancement of agricultural practices in Indonesia, particularly in wetland tillage, through the introduction of Android-controlled hand tractors is essential to tackle the challenges posed by diminishing labor and agricultural land. This study aimed to evaluate the financial viability of implementing a Wi-Fi-based Android-controlled hand tractor in comparison to manual operation. The methodology encompasses technical field capacity testing, cost efficiency, and financial assessment. The financial analysis of the five-year investment simulation revealed a Net Present Value (NPV) of IDR 19,918,961, an Internal Rate of Return (IRR) of 28.03%, a payback period of 1.78 years, and an ROI of 60.15%, which is 10.4% lower than the conventional method. These findings suggest that investing in this technology is not only financially feasible but also profitable. The adoption of Android-controlled hand tractors enhances productivity and has the potential to yield substantial economic returns for the agricultural sector.

Abstract

Masyarakat Desa Permata Baru, yang terletak di Kecamatan Indralaya Utara, Kabupaten Ogan Ilir, menjadi fokus utama pelaksanaan kegiatan pengabdian sosialisasi tahun 2024 oleh tim pengabdian Universitas Sriwijaya. Sebagai salah satu desa binaan universitas, Permata Baru menyimpan potensi agraris yang menjanjikan, tidak hanya terbatas pada pertanian lahan basah, namun juga pertanian lahan kering atau ladang. Mayoritas petani di desa ini memiliki keahlian dalam menghasilkan beragam komoditas, mulai dari jeruk lemon, aneka sayuran, produk hortikultura yang bervariasi, hingga pembibitan kelapa sawit yang memiliki nilai ekonomi tinggi. Kendati demikian, praktik pertanian hortikultura di Desa Permata Baru saat ini sangat bergantung pada ketersediaan pupuk anorganik dan kondisi iklim yang seringkali tidak menentu. Keterbatasan pasokan pupuk anorganik bersubsidi di pasaran menjadi permasalahan krusial, sehingga memicu kenaikan harga yang signifikan. Situasi ini secara langsung membatasi hasil panen yang dapat diperoleh petani, yang pada akhirnya berdampak pada penurunan pendapatan mereka. Dalam upaya memberdayakan masyarakat dan meningkatkan kesejahteraan petani, khususnya mereka yang memiliki potensi produksi mandiri, Unit Pengelola Kegiatan (UPK) PKK "Beguyur" kembali diaktifkan pada tahun 2018 dengan mengusung sistem simpan pinjam. Langkah strategis ini diharapkan dapat memberikan akses modal bagi anggota PKK untuk mengembangkan usaha pertanian mereka. Adanya kegiatan sosialisasi mengenai sistem evapotranspiratif dan praktik pertanian organik direncanakan untuk memberikan pengetahuan dan keterampilan baru kepada petani dan anggota PKK "Beguyur". Diharapkan, melalui pemahaman dan penerapan metode pertanian berkelanjutan dan efisien, produksi pertanian dan pendapatan penduduk Desa Permata Baru dapat meningkat secara signifikan.
