“…Fixed-bed type gasifier was also tested using candlenut shell and coconut shell which can be used to produce flammable gas as shown in Figure 4f [103]. The use of producer gas for IC engines in Indonesia has a promising future for power generation where engines can operate with a minimum heating value of 3 MJ/m 3 [104]. The drawback of this technology is mainly related to the upscaling due to the limitations in large-scale biomass supply, transportation, and treatment.…”

Government policies in Indonesia have been pushing in the past decade towards 100% electrification target by end of 2020. However, many of the new energy policies are reused from previous policies designed for different objectives causing overlap in policies between the central and local governments. Local distributed generation are not fully controlled by local stakeholders and community, and with the lack of long-term planning, continuous government incentives and support, they are bound to fail due to the lack of maintenance. The use of solid biomass for household has decreased significantly due to the government support for LPG stoves that overtaken other government projects supporting biomass. Small-scale biomass research is showing good progress towards the implementation of novel methods for biomass utilization. However, majority of the medium and large-scale projects are still relying on old technologies such as direct biomass combustion in boilers rather than the more environment friendly gasification technology. Another major biomass contribution to national energy mix is through liquid biofuels. This work summarizes the current and prospective energy mix in Indonesia and the main conventional and non-conventional energy sources and their environmental concerns. This work also gathers the latest local biomass research and biomass power plant projects.

“…The position of pyrolysis technology among thermochemical processes is superior because it can produce high -value products and relatively easy to use. The gasification process indeed has the advantage of producing high calorivic value producer gas, but in terms of reactor and operation, it is more complicated than pyrolysis [5][6][7][8][9][10]. Slow pyrolysis is the most preferred by industrial of wood processing enthusiasts because it can produce high-grade charcoal and bio-oil for trading.…”

This study aims to produce liquid smoke that will be used as plant pesticide by means of pyrolysis of a mixture of two types of biomass, coconut shells (CS) and empty fruit bunches (EFB). The parameters used are the ratio of the mixture of the two materials and the pyrolyse temperature ranges from 300 to 500 o C. A reactor of 2 kg capacity with indirect heating is used for this study. Heat is obtained from LPG combustion using a burner. Feedstock used in the form of pieces of coconut shells aproximately 5 x 5 cm 2 and the EFB of 3-5 cm in length are first dried using sun energy until they reach a standard dryness. Three difference of feedstock mixture composed of CS and EFB based on mass ratio (Mr) of 25:75, 50:50, and 75:25 are used to know their effect on the liquid product yield. During the process, the smoke is passed through the cyclone to reduce tar content, and then flows into the condenser with a water cooling fluid. After the specified duration of pyrolysis is reached, the LPG is turned off and the furnace is left for cooling. After that, the pyrolysis products; the liquid smoke and the char are collected. The influence of operating parameters such as temperature, heating rate, process duration, and the feedstock mass ratio were considered associated with the quality of the liquid smoke.

“…Simanjuntak, dkk (2015) berhasil mendapatkan nilai pembakaran biomassa jenis serbuk kayu sebesar 7 MJ/m 3 dengan menggunakan reaktor fluidized bed jenis sirkulasi internal [2]. Nilai CV dari biomassa sebesar ini sudah lebih dari cukup untuk digunakan sebagai bahan bakar pada mesin-mesin pembakaran dalam, motor bensin ataupun diesel [3] dan mesin pembakaran luar seperti turbin gas [4,5]. Namun teknik gasifikasi ini mempunyai kelemahan dalam hal perlakuanatau treatment biomassa sebagai bahan bakar.…”

Kombinasi antara reaktor pembangkit energi panas dari sumber energi terbarukan dan mesin pembangkit tenaga menggunakan mesin Stirling atau disebut cogeneration menjadi sebuah teknologi yang menjanjikan dalam menjawab tantangan penyediaan energi masa depan dari sumber energi terbarukan khususnya sumber energi dari biomassa. Tujuan artikel ini adalah memberikan review secara teoritis dan analitis bagaimana sebuah mesin Stirling yang terintegrasi dengan reaktor pembakaran biomassa mampu menghasilkan tenaga. Artikel ini juga bertujuan untuk memberi pemahaman yang lebih mendalam kepada mahasiswa yang sedang mempelajari mata kuliah khususnya terkait konversi energi termal. Banyak mesin-mesin termal yang dibicarakan dalam ruang kelas perkuliahan, namun itu semuanya secara sendiri-sendiri. Namun di dunia industri yang menggunakan mesin-mesin termal bahwa sistem termal tentunya adalah gabungan dari mesin-mesin termal yang bekerja secara bersama-sama. Implementasi rumus–rumus dasar, asumsi–asumsi yang digunakan untuk menganalisis suatu peralatan teknik yang melibatkan suhu, tekanan, dan aliran yang berkaitan dengan mesin termal lain dalam satu sistem akan membuat pemahaman para mahasiswa akan semakin baik dan mantap.
