Briquettes are a type of alternative energy whose raw material source Plastic waste is an environmental problem faced by the people of Indonesia and the world. On the other hand, the production of waste generated in various institutions and sectors in Indonesia continues to increase every year, including the industrial sector whose production process is large-scale. Its use as a basic material for packaging bottles reaches 30% of world use. PET is also used as a synthetic fiber or polyester which accounts for 60% of world use. Study the author will do that is to make a tubing made from PET plastic waste that can be used as raw material for tubing. Using temperature variations (190?, 200?, 210?), then 9 samples from each variation will be micro-photographed the effect of temperature on tubing results and tested for maximum tensile. After that, calculations are carried out to obtain the maximum tensile stress and strain values. Then the average maximum load value that can be received by PET tubing is highest at 190ºC temperature tubing has the ability to withstand tensile strength better than all temperature variations so that the average value is 35.94 N/mm2 and 200ºC is able to withstand 35.49 N/mm2 and 210ºC with 18.30 N/mm2. It can be interpreted that the higher the temperature, the effect on holding the tensile strength of the PET tubing and making the plastic structure change so that 210oC is close to the recycling value, while for temperatures below it is still non-recycled.

Candlenut shell is an organic waste that has a hard texture and has a high carbon element. The amount of candlenut shell produced from each processing of candlenut seeds is very large but has not been optimally utilized. For this reason, an effort is needed to utilize candlenut shells so that they do not become waste. In the manufacture of hazelnut shell briquettes, hazelnut shells are carbonized at 500 °, sifted with mesh 30 and 100 sieves, given a compressive load of 3 kg, 4 kg, 5 kg and 5.5 kg, the adhesive on hazelnut shell briquettes is starch and drying is carried out with a drying oven for 3 hours at a temperature of 80 °. The purpose of this study was to determine the effect of variations in pressure and particle size on the quality of hazelnut shell briquettes when viewed from the combustion rate and calorific value. The methodology used in this research is experimentation on hazelnut shell briquettes, testing hazelnut shell briquettes including testing water content, testing ash content, burning rate and calorific value of briquettes. From the results of the research on hazelnut shell briquettes with variations in pressure and mesh, the highest calorific value in hazelnut shell raw material briquettes is in the 5.5 Kg pressure specimen on mesh 30, namely 9855.18 Cal/gram and the bomb calorimeter test results are 7008.03 Cal/gram with an error rate of 24.40%, the higher the pressure will produce a higher calorific value as well. The highest combustion rate value is in hazelnut shell briquettes at a pressure specimen of 3 Kg mesh 100 with a value of 1.2 grams/minute the smaller the particle size, the higher or faster the combustion rate.

The current fuel is still sourced from fossil fuels, namely oil, coal and The current fuel is still sourced from fossil fuels, namely oil, coal and gas, which have many impacts on the environment. As an agricultural country located in the tropics, Indonesia is rich in biomass energy sources. In this research, the use of candlenut shells will be used or processed into alternative fuel, namely briquettes, with the aim of determining the value of combustion time and temperature produced through variations in composition and mesh size. The results of the research show that the effect of the burning temperature has an impact on the burning time of the briquettes and the resulting temperature, where the best burning time and temperature values ??of the briquettes are produced by a burning temperature of 400°C with a grain size of 100 mesh, namely 177 minutes with an average burning temperature briquettes 193.9°C.

AbstrakPerkembangan di era Industri 4.0 pada saat ini menuntut kemampuan sumber daya manusia yangharus mengikuti pula akan perkembangan teknologi. Berhubungan dengan hal tersebut, ParokiGereja Ijen Malang menginginkan Putra-Putri Altar (PPA) selain mampu menjalankan tugaspelayanan dengan baik juga diharapkan mampu mengembangkan kemampuannya dalammendokumentasikan kegiatan-kegiatan PPA, membuat desain untuk keperluan publikasi kegiatan,dan mempublikasikan kegiatan tersebut. Dari permasalahan tersebut, maka diperlukan pelatihanketerampilan desain. Pelatihan dalam kegiatan IbM ini bertujuan untuk meningkatkan kemampuanPPA Paroki Santa Perawan Maria dari Gunung Karmel - Gereja Ijen Malang dalam mendesainmenggunakan CorelDRAW dan desain bangunan menggunakan Autodesk Revit Building.Hasil dari pelatihan ini adalah peserta dapat memahami materi yang disampaikan dengan baik dandapat mengaplikasikan dalam project kecil dengan pembuatan logo, pembuatan layout sederhanauntuk cover majalah. Selain dari itu, tingkat pemahaman peserta pelatihan juga meningkat. Hal inidibuktikan dengan rekapitulasi hasil pre-test dan post-test.Kata kunci: desain grafis, desain bangunandigital, dokumentasi, pelatihan
AbstractDevelopments in the Industrial 4.0 era currently demand the ability of human resources to keepup with technological developments. In this case, Ijen Parish Church Malang expects the Altar Servers(Putra-Putri Altar - PPA), in addition to being able to carry out their ceremonial duties properly, tobe able to develop their abilities in documenting PPA activities, making designs for publicationpurposes, and publicizing the activities. These problems suggest that design skills training is needed.The training in this IbM activity aims to improve the ability of the Parish of the Blessed Virgin Maryof Mount Carmel - Ijen Church Malang in using CorelDRAW for design and using Autodesk RevitBuilding for designing buildings.The result of this training is that after the implementation of the training the trainees are able tounderstand well the material presented and apply it in small projects by making logos and simplelayouts for magazine covers. Furthermoret, the comprehension level of the training results in thetraining participants show an increase as evidenced by the recapitulation of the pre-test and post-testresults.Keywords: graphic design, digital building design, documentation, training
