Abstract

Coconut shells and rice husks as alternative raw materials to reduce the use of inorganic energy, from the results of previous research, rice husks have a low calorific value, so to increase the calorific value it is necessary to add other materials that have a better calorific value, other alternatives as The support is coconut shell. The research method was carried out using experimental testing, starting with the burning process to become charcoal, the process of refining the material (mesh), the molding process, and the drying process, the briquette lab test process. In the mixing process, the adhesive material is bran adhesive with a concentration of 1.3. The aim of this test was to analyze the calorific value, water content and amount of ash contained in the briquettes. The research results showed that the calorific value of rice bran husks was 4375.42 Calories/gram, air content 23.43%, dust content 33.79%, and for rice husk coconut shell the calorific value is 5925.96 calories/gram, water content 19.4%, dust content 18.3%

Abstract

Automatic Guided Vehicle (AGV) adalah sebuah mobile robot yang mengikuti petunjuk atau garis yang diberikan di lantai atau menggunakan laser atau dapat pula berupa logam bermedan megnet untuk bergerak kearah tertentu. Penelitian ini akan dianalisa cara untuk Mengefektifkan proses pemindahan secara manual menjadi otomatis sehingga dapat menghilangkan 1 MP dan menekan biaya produksi. Dari hasil penelitian diperoleh hasil daya output 0,2 kW pada torsi 0,6292 Nm dengan tingkat efesiensi mencapai 75%. Untuk hasil perhitungan hubungan antara daya, kecepatan dan torsi serta pengujian maka diperoleh beban maksimal yang dapat diangkut oleh robot adalah 500 kg / 5000 N, jika di asumsikan tanpa beban adalah 30 kg / 300 N (berat rangkaian) sinyal pwm dengan jumlah pulsa 240 atau dengan kecepatan motor 3000 rpm

Abstract

Utilizing agricultural and household waste as renewable solid fuels offers a sustainable approach to reduce dependence on fossil fuels and improve waste management practices. This study experimentally investigated the effects of different proportions of coconut-shell charcoal and ESP on the physical and thermal performance of biomass briquettes using 10 wt% ESP. % tapioca starch as the binder. Three briquette formulations with different coconut shell charcoal–ESP (CS–ES) ratios were prepared and evaluated in terms of moisture content, calorific value, and burning duration. The results showed that increasing the proportion of coconut shell charcoal significantly improved briquette performance. The optimum formulation (CS–ES3) achieved the lowest moisture content (7.05%), highest calorific value (7400 cal g⁻¹), and longest burning duration (130 min). Statistical analysis confirmed significant differences among the tested formulations (P < 0.05). The calorific values of all briquette formulations exceeded the minimum requirement specified by SNI 01-6235-2000, and the optimum formulation satisfied the maximum-allowable moisture content. These findings demonstrate that CS charcoal and ESP can be effectively used to produce biomass briquettes with promising fuel characteristics for renewable energy applications and sustainable biomass waste utilization.
