Liquid smoke is the result of condensation or condensation from the steam resulting from pyrolysis (combustion). From ingredients that contain lotsof lignin, cellulose, hemicellulose and carbon compounds which can be used as preservatives. Sawdust and coconut shell are sawdust, which is waste from the remains of refining wood on furniture and market waste from coconuts which are taken from coconut milk and oil. Both contain cellulose, hemicellulose, and lignin, these ingredients can be made into liquid smoke. The purpose of this study was to utilize sawdust and shell waste as liquid smoke which could be applied to the pickling and clumping industry. Making liquid smoke is done using a pyrolysis device. The liquid smoke formed is filtered. Then the yield was calculated and analyzed the quality of the liquid smoke, namely specific gravity, pH, and color. The results showed that the yield of sawdust was higher than coconut shell, namely 45.09%. And the resulting color is better sawdust.

The microwave hydriffusion gravity (MHG) method is a relatively new extraction method in order to improve the quality of oil obtained from plant materials or spices. The extraction process is carried out without involving solvents so it is safe for consumption. However, the MHG method has never been applied to the extraction of candlenut (Aleurites moluccana L) seeds. The operating conditions and variables in the research on the extraction process of Aleurites moluccana L are microwave power (300; 450; 600 W), extraction time (15-75 minutes) with 15-minute intervals, material size (1;2;3 cm), mass of raw material 100 gr, and atmospheric pressure. Material treatment consisted of 3 types of material conditions including seed material which had been roasted for 10 minutes over low heat, seed material which had been in the oven for 45 minutes, and seed material which had been without pretreatment. The results of the oil extract were analyzed using GC-MS to identify the components of the constituent compounds. Then, evaluating the mathematical modeling of the extraction process is based on first and second order kinetics. Roasted material showed the highest yield with material size parameter in 1 cm, microwave power of 600 W, and extraction time at 30 minutes, produced 5.55% (%w/w). Furthermore, the pyrazine component (36.814%) is the largest compound from the extraction of Aleurites moluccana. The first-order kinetic model has a regression that is close to the experiment with (R2 = 0.9453). Modeling quality is also supported by a very small total sum of squares (SST) value of 6,44E10-4. Therefore, the MHG method is quite effective in producing Aleurites moluccana oil with better quantity and quality

OPT problems are still a major obstacle to organic rice cultivation due to limited understanding and control skills. The aim of implementing community service activities is to provide additional skills and insight regarding OPT control technology with local biological agents to solve the problem of organic rice farming in Bumiagung village, Tegineneng, Pesawaran. Technology transfer activities regarding the application of control with local biological agents to solve the problem of pest attacks on organic rice plants were carried out in Bumiagung Village, Tegineneng, Pesawaran which were carried out in June - October 2022 to the Progressive Organic Farmers Community. The stages of the activity are carried out in stages through conducting surveys, providing material, pre-testing, training and mentoring, post-testing, monitoring, and evaluation at the end of the activity. Before the activity begins, a survey is carried out to analyze conditions and problems and analyze the solutions needed for these problems. Farmers need to gain more knowledge and skills in managing pests that attack their land. The controls that are often used are vegetable pesticides and refugia. From the final evaluation results, the analysis shows that farmers realize that control with biological agents is effortless, inexpensive, and synergistic in supporting organic farming.

Bamboo is one of the biomass resources that Indonesia has a lot of untapped potential for using as a renewable energy source. Solid waste called biomass is used as a sustainable energy source to replace fossil fuels (i.e., petroleum), because it does not contain Sulphur and pollute the air. This study aimed to evaluate the quality of bio briquettes produced from waste charcoal from bamboo pyrolysis. being aware of the maximum calorific value depending on the adhesive quantity and particle size. Moreover, understand how the size of the particles and the amount of adhesive used impact the calorific value of bio briquettes. This study employed the pyrolysis of bamboo charcoal as its raw material. The charcoal's particle sizes varied, ranging from 30 to 50 mesh, and the percentage of tapioca adhesive varied from 6% to 10%, with a 1:10 adhesive to water ratio between the three samples. The results of the tests that have been carried out show that bamboo charcoal from bamboo pyrolysis can be used as bio briquettes of good quality. The highest calorific value was found in bio briquettes, with a variation in the percentage of adhesive of 6% and a particle size of 50 mesh, which was 6131.58 calories per gramme. The greater the percentage of adhesive used, the smaller the resulting calorific value, and the smaller the particle size used, the greater the resulting bio briquette calorific value.

Pelaksanaan pendidikan berpedoman pada kurikulum yang telah disusun secara sistematis dan bertahap yang diterapkan dalam proses pembelajaran. Pengembangan pendidikan Sekolah Menengah Kejuruan (SMK) di Indonesia harus diarahkan untuk beradaptasi dengan dinamika global dan nasional khususnya terhadap Revolusi Industri 4.0 saat ini, menyesuaikan dengan kebutuhan dunia kerja dengan menyempurnakan kurikulum dan mengintegrasikan dengan banyak pemangku kepentingan. SMK Negeri 8 Bandar Lampung berdiri berdasarkan Surat Keputusan Wali Kota Bandar Lampung Nomor 511/14.40/HK/2014 tanggal 11 April 2014. Kurikulum yang digunakan di SMK Negeri 8 Bandar Lampung adalah Kurikulum Merdeka. Bandar Lampung saat ini adalah terbatasnya pengetahuan dan keterampilan guru dalam pemanfaatan teknologi software engineering SuperPro Designer yang digunakan dalam bidang Teknik Kimia Industri. Padahal SMKN 8 Bandar Lampung memiliki fasilitas Laboratorium Komputer yang memadai namun belum terpasang software pendukung lanjutan Teknik Kimia khususnya aplikasi SuperPro Designer. Dengan adanya kegiatan PKM ini diharapkan fasilitas pendukung dalam proses belajar dalam hal ini aplikasi SuperPro Designer dapat meningkatkan pengetahuan dan keterampilan guru di SMKN 8 Bandar Lampung.
