Abstract

The squeezing process of grated coconut into coconut milk, and the following process of  making the milk into coconut oil, which is done by people living in rural areas, is until now still very traditional. They do it manually (by hands) so that they produce 7.2 kg/hour grated coconut or 3.6 litres/hour thick coconut milk.To effectify the process, the squeezing needs to be mechanized, using a grated coconut squeezer machine.The machine is designed on the basis of Screw Press system with a ¼ HP 1450 rpm electric motor power using a pulley belt transmission and a gear box. The squeezer’s force refers to coconuts aging between 341 and 413 days (hand squeezing force normally practised by coconut oil producers in rural areas).This prototype of machine has the capacity of producing 53.2 kg/hour grated coconut or 26.6 litres/hour thick coconut milk, which has similar quality (in colour, smell and texture) as that manually squeezed.Keywords : grated coconut squeezer, coconut milk

Abstract

The home industry partner for the tofu business is located in Kalidoh Langensari Barat Village, Ungaran Barat District, Semarang Regency. The partner's obstacle is the failure to meet the increasing market demand. This obstacle is caused because the production process is still carried out manually or traditionally so that tofu production is limited to human power. The right solution offered through this community service is the application of process technology in the form of a soybean grinding machine with a rotary system to increase tofu productivity. The purpose of this community service is to make an electric soybean grinding machine, apply a rotary grinding machine to the tofu production process, and conduct evaluation and assistance to maintain the sustainability of the program. The initial stage carried out in this service consists of planning and making the machine. Planning is based on market needs and partner conditions related to the provision of electrical energy. The design results are made through machine work in the Mechanical Department workshop. The next stage is the application of the machine including assembly and installation of the machine at the partner's location, as well as operational training and machine maintenance. The final stage of the service is evaluation and assistance. Evaluation is carried out by directly assessing the partner's operational practices on the machine that has been assisted. The assistance provided includes supervision, work control, and direction when the partner produces tofu using the production machine. It is expected that the rotary soybean grinding machine can increase the production of partner tofu.

Abstract

Maintenance and repair work in a building or structure is not only in low places, but also in high places which require assistive devices. The assistive device in question is scaffolding. The design of this scaffolding begins with a literature study followed by data collection in the Mechanical Engineering Department of the Semarang State Polytechnic to obtain data on the need for height assistive devices which are used as a reference for making electric scaffolding. The purpose of this study is to design an electric scaffolding with a capacity of 300 kg and to perform the performance of the electric scaffolding made. After the design of the electric scaffolding, the dimensions of the equipment were obtained, namely 1000 mm x 1500 mm x 2000 mm and specifications that can lift goods with a maximum height of 5 m, a minimum height of 0.35 m, a maximum load of 300 kg and an AC 220 V electric hoist drive. Based on the results of the performance test, in this case the test data was taken from the weight of the load that the machine can lift based on the travel time when the machine moves up and down. The load weight of 300 kg with electric scaffolding was covered in 27.44 seconds when going up and 21.02 seconds when moving down.

Abstract

Conventional heating methods remain prevalent among small and medium-sized enterprises (SMEs) for aluminum mold thermal regulation during resin-coated sand (RCS) core production. Inconsistent thermal regulation significantly alters the characteristics of resin-coated sand cores. This study aims to investigate the effect of curing parameters on the compressive strength and toughness of the resin-coated sand. The RCS specimens were prepared using an aluminum mold that underwent controlled thermal treatment in an electrical furnace. The thermal treatment is performed by processing specimens across a curing temperature range of 200-300°C and varying curing time from 3 to 15 minutes. HDPE polymer was proposed as the RCS binder. Compressive and impact tests were carried out to determine the characteristics of resin-coated sand. The results showed a non-linear relationship between curing parameters and mechanical properties. Although moderate curing time and higher temperatures initially improve compressive strength and toughness, exceeding optimal thresholds leads to the degradation of these mechanical characteristics. The highest mechanical properties (compressive strength = 38.4 MPa, toughness = 0.43 MPa) are achieved through a curing temperature of 250°C and a curing time of 9 minutes. This study provides valuable insights into determining the optimal parameters for processing resin-coated sand cores or molds with superior compressive and toughness properties.

Abstract

Objek yang menjadi mitra kegiatan pengabdian adalah CV. Rejeki Abadi Machinery (CV RAM) yang bergerak di bidang pengecoran logam. Dalam proses produksinya, perusahaan menggunakan pasir silika sebagai bahan utama dalam pembuatan cetakan untuk komponen pompa. Permasalahan yang dihadapi mitra adalah belum dimanfaatkannya limbah dari proses pengecoran di CV.RAM khususnya pasir silica, sehingga biaya produksi menjadi tinggi. Solusi yang diberikan adalah pasir silica setelah digunakan direcycle sehingga dapat menekan biaya produksi. Metode yang akan dipakai untuk pelaksanaan rencana tersebut yaitu: tahapan perencanaan, pelaksanaan program dan pendampingan sampai evaluasi kegiatan mitra. Hasil pengabdian yang dilakukan dengan teknologi tepat guna berupa mesin pengayak pasir yaitu kebutuhan pasir silika baru mencapai 25 ton per bulan, berkurang menjadi 16 ton per bulan setelah alat diterapkan. Hal ini menunjukkan efisiensi penggunaan pasir silika daur ulang sebesar 9 ton per bulan. Meskipun harga pasir silika tetap Rp. 800.000,- per ton, total biaya pembelian menurun dari Rp. 20.000.000,- menjadi Rp. 12.800.000,- per bulan, sehingga penghematan biaya perbulan dapat dicapai sebesar Rp. 7.200.000,- atau 36% dari total biaya sebelumnya.
