Abstract

In the context of vocational education, technicians play a crucial role as partners to teachers in laboratory or workshop settings in schools specializing in machining technology. Despite having received training at their institutions, many technicians lack sufficient competence to optimally support learning activities. This community service initiative aims to enhance the professional competence of technicians in vocational schools through a structured approach. The activity begins with a field study to assess specific needs, followed by the development of a training model that is then reviewed through a Focus Group Discussion (FGD). This training model is designed to provide technicians and laboratory teachers with comprehensive insights into best practices and effective self-development guidelines. The expected outcome is a significant improvement in the competencies of technicians and laboratory teachers in Bandar Lampung.

Abstract

Abstrak Pleurotus ostreatus mushroom cultivation is a promising business opportunities in Bandar Lampung, as for one mushroom’s growing media (baglog) may produces for harvesting mushrooms every day up to 4-5 months. However, the success and quality of the mushroom production depends on the quality of mushroom’s growing media (baglog) preparation. Baglog preparation process is done through several steps, starting with preparing and mixing the raw materials to get a homogeneous and optimal dough, then subsequent compression and packaging of growing media in a plastic bag, before sterilizing and placing the oyster mushrooms stem at the top of baglog. In the small-scale mushroom industry, the process of mixing and compression of growing media used to be done manually or by human power. This process may give a low degree of homogeneity and uncompact baglog. The objection of this community service program is to implement an automatic mixer and compression tools for baglog production at oyster mushroom plantation center at Pesantren Darussalam, Banjar Negeri, Natar, South Lampung. Kata kunci: Pleurotus ostreatus mushroom, baglog, mixer machine, compression tool

Abstract

This study investigates the effects of rolling direction and grain orientation on the mechanical properties of AZ31B magnesium alloy, with a focus on its application in biodegradable implants. The research was conducted experimentally by preparing tensile test specimens from AZ31B sheet plates, cut in two different directions: parallel (0°, X) and perpendicular (90°, Y) to the rolling direction. Static tensile testing was performed in accordance with ASTM B557 standards to measure the material's mechanical properties. The results indicate mechanical anisotropy, where specimens in the X direction exhibited an average yield strength of 198.78 MPa, while specimens in the Y direction achieved a value of 78.21 MPa, only 39.3% of the X direction value. This difference is attributed to the formation of crystallographic texture during the rolling process. The modulus of elasticity showed similar properties, with values of 44-45 GPa in both directions. These findings demonstrate that grain orientation and rolling direction significantly affect the mechanical properties of the material, which is crucial in designing degradable magnesium AZ31B implant materials.

Abstract

Glass-ceramics are fine-grained polycrystalline materials produced by controlled crystallization in the glass phase. The raw material for glass ceramics is basalt rock from East Lampung mixed with additives (SiO₂, MgO, and CaO). The production of glass ceramics begins with melting at 1200 °C for 2 hours until melting. The melted basalt is quenched using aquadest water with a pH of 7 to produce glass material. The glass material is ground using a ceramic ball mill and sieved with a 325 mesh. The glass material undergoes nucleation at 600 °C for 2 hours, followed by crystallization at 1,050 °C for 3 hours, and thermal crystallization (devitrification) at 1,050 °C for 3 hours to form the crystalline phase. The additive composition was varied using the Taguchi method to analyze its effect on density. The density test results showed values ranging from 2.1 to 3.8 g/cm³, depending on the additive ratio used. An increase in CaO and MgO content tends to increase density due to the formation of crystalline phases such as pyroxene, anorthite, and olivine. Conversely, excessive addition of SiO₂ can reduce density due to the growth of amorphous phases. Taguchi analysis identified Silica (SiO2) as the Rank 1 parameter influencing density. Meanwhile, ANOVA analysis yielded an optimal percentage contribution of silica at 34.57%.

Abstract

This article discusses bimetal welding between AISI 1040 steel and AISI 1020 steel using the Shielded Metal Arc Welding (SMAW) method with AWS E 7016 electrodes. The purpose of the study was to evaluate the quality of the welded joint, including the mechanical properties and microstructure of the bimetal welding results. The use of high-strength AISI 1040 steel and AISI 1020 steel with malleable properties aims to produce a joint that optimizes the characteristics of each material. The welding process was carried out with varying current parameters to determine its effect on the welding results. Testing included tensile testing, hardness testing, impact testing, and microstructure analysis. The results showed that variations in welding parameters affected the mechanical properties of the joint and the distribution of microstructures in the weld zone, heat-affected zone (HAZ), and base metal. The optimal welded joint was obtained by setting certain current parameters that produced maximum tensile strength and even hardness distribution. This study contributes to the development of bimetal welding technology, especially for applications that require a combination of mechanical properties of two types of steel.

Abstract

Abstrak   Kusen merupakan bagian terpenting dari bangunan rumah, di Indonesia kusen kayu masih banyak digunakan. Dengan semakin berkurangnya persediaan kayu bermutu maka perlu dicari alternatif penggantinya. Kusen beton dapat menjadi alternatif pengganti kusen kayu. Untuk memperkuat ikatan pada kostruksi perlu ditambahkan serat pada bagian sambungannya. Serat tandan kosong kelapa sawit (TKKS) yang persediaannya sangat melimpah dijadikan bahan yang berfungsi sebagai pengikat. Penggunaan TKKS dapat mengurangi permasalahan pencemaran pada pabrik kelapa sawit. Dengan adanya serat TKKS pada bagian sambungan antara kusen yang sudah kering pada saat pemasangan  dinding yang masih basah akan menjadi pengikat pada sambungan. Sehingga dengan tambahan TKKS, maka ikatan antara sampungan kusen dengan didnding dapat mencapai 3,9 MPa. Terlepas dari jenis serat yang digunakan maka penambahan serat menjadi sangat penting pada proses pembuatan kusen beton. Dengan demikian peran TKKS pada kusen beton sangat penting karena dapat meningkatkan ikatan sambungan dan dapat mengurangi permasalahan pencematan pada tempat pengolahan kelapa sawit.   Kata kunci: Kusen Beton, Serut, TKKS     Abstract   Frames are the most important part of a house building, in Indonesia wooden frames are still widely used. With the decreasing supply of quality wood, it is necessary to look for alternative replacements. Concrete frames can be an alternative to wooden frames. To strengthen the bond in the construction, fibre needs to be added to the joints. Oil palm empty fruit bunch fibre (OPEFB), which is in very abundant supply, is used as a material that functions as a binder. The use of OPEFB can reduce pollution problems in palm oil mills. With the presence of OPEFB fibre in the joints between the frames which are already dry when installing the walls which are still wet, it will act as a binder in the joints. So with the addition of OPEFB, the bond between the frame joint and the wall can reach 3.9 MPa. Regardless of the type of fibre used, the addition of fibre is very important in the process of making concrete frames. Thus, the role of TKKS in concrete frames is very important because it can improve joint bonding and can reduce contamination problems at palm oil processing sites.   Keywords: Conrete frame, scrap, OPEFB
