Abstract

Injeksi plastik merupakan proses pembentukan produk dari material plastik dengan variasi bentuk dan ukuran. Hasil injeksi plastik harus memenuhi tuntutan antara lain, bentuk ukuran dan tampilan yang baik atau tidak boleh ada cacat pada permukaan misalnya shinkmark, air trap danpermukaan yang tidak halus. Material plastik yang digunakan antara lain polypropylene, polysterene, plastik campuran. Proses pembentukan produk plastik membutuhkan variasi parameter suhu pemanas, pendinginan, waktu tahan dan kecepatan injeksi. Metode yang digunakan adalah metode eksperimen berupa variasi suhu 270°C, 300°C dan 330°C yang diberikan pada tiga kali percobaan disetiap suhunya. Setelah dilakukan penelitian didapatkan hasil nilai shrinkage panjang dan shrinkage diameter pada mesin injeksi molding. Nilai dari hasil pengujian variasi suhu bersifat fluktuaktif dengan nilai shrinkage ketebalan terbesar 1,3 mm, nilai shrinkage tinggi 3,7 mm. Setelah dilakukan pengujian semakin besar suhu maka semakin besar nilai shrinkage

Abstract

The process of forming materials is often carried out in the manufacturing industry, especially in the process of forming plastic materials. One method is the injection blow molding, which is done by blowing air into a mold that has been previously designed. The need for a level of precision and accuracy in designing a mold using the injection molding process is one of the important things in the injection blow molding process. One of the designs that must be considered when printing a bottle-shaped product is that it must be precise, in accordance with the expected product design, by considering machine and mold design, material selection, molding materials, and manufacturing processes. The aim of the research is to determine the influence of temperature and pressure on thickness and shrinkage in molds with 30 ml bottle shape. From the results of tests that have been carried out, the effect of a pressure of 4 bar and a temperature of 160 °C produces an average thickness of the mold of 1.03 mm, while at a pressure of 4 bar and temperature of 180 °C the average thickness is 1 mm. The standard used for bottle products is less than 1 mm so that the pressure 4 bar from the experimental results meets the standards for injection blow molding process mold results and for shrinkage occurs at 0.681 %.

Abstract

The Lam Teuba Formation is one of the local fault areas of the Seulimuem segment located in the Grand Mosque sub-district of Aceh Besar regency. The Lam Teuba Formation has several types of rocks such as basaltic andesite lava, pyrolastic flows, pyroclastic falls, and sedimentary rocks, namely claystone, limestone sandstone, agglomerate, limestone. Rocks have physical characteristics, namely density and porosity which have different values in each rock. This difference can be caused by the minerals contained in the rock. The method used to calculate the density and porosity values used the Archimedes method, and the identification of mineral types using the infrared spectroscopy method. The results of data processing obtained the highest original density value at location 1 sample 1 with a value of 3.42 and the lowest value at location 5 sample 2. The highest dry density value was in location 1 of sample 1 with a value of 3.33 and the lowest value was in location 5 of sample 2. The highest saturation density value was in location 1 of sample 1 with a value of 3.43, the lowest value was in location 5 of sample 2 with a value of 2.07. The average porosity value was the highest with a value of 5.41 in the poor quality category in sample 4, while the lowest value was 4.62 in the very bad category in sample 1. The types of minerals found in the Lam Teuba formation are illite, montmorillonite, kaolinite minerals with a mixture of smectite which is a clay mineral group and siderite minerals which are carbonate mineral groups.

Abstract

ABSTRAKArtikel bertujuan untuk memberikan deskripsi pelaksanaan workshop tentang implementasi Activity Based Costing (ABC) bagi para pelaku pengobatan tradisional (paricara). Berdasarkan data statistik, pengobatan tradisional telah menjadi alternatif utama bagi layanan kesehatan modern di Indonesia, terutama di daerah-daerah yang sulit dijangkau oleh kesehatan modern. Implementasi metode Activity Based Costing (ABC) diharapkan mampu meningkatkan laba bagi para pelaku pengobatan tradisional. Metode pengukuran keberhasilan workshop menggunakan one group pretest-posttest design dengan melibatkan 20 peserta. Hasil pengujian menunjukan bahwa implementasi metode ABC mampu meningkatkan akurasi penentuan biaya produksi, sehingga berdampak positif terhadap peningkatan laba para pelaku pengobatan tradisional. Kata kunci: pengobatan tradisional; activity based costing; laba; perhitungan biaya; peningkatan profitabilitas. ABSTRACTThis article aims to delineate the implementation of workshop focused on the application of Activity Based Costing (ABC) for practitioners of traditional medicine (paricara). Based on statistical data indicate that traditional medicine has emerged as a viable alternative to modern healthcare services in Indonesia, particularly in regions with limited access to modern medical facilities. The adoption of the ABC is anticipated to enhance profitability for traditional medicine practitioners. The efficacy of workshop is asses using a one-gorup pretest and post tes design involving 20 participants. Results demonstrate that the application of the ABC method significantly improves the accuraccy of production cost, thereby positively influencing profit margins for practitioners of traditional medicine. Keywords: traditional medicine, activity based costing; profit; cost calculation; profitability enhancement

Abstract

Indonesia possesses rich biodiversity with the potential to serve as a source of economic growth, one example being the sugar palm plant (Arenga pinnata) found in Kasepuhan Sinar Resmi, Sukabumi Regency. This community service activity aims to address challenges in the traditional palm sugar processing methods, which are time- and energy-consuming, as well as in marketing management, which remains underdeveloped. The activities were carried out through several stages: preparation, implementation, evaluation, and monitoring. During the implementation stage, modernized equipment for palm sugar processing was developed to simplify and improve the traditional methods. In addition, training in information technology-based marketing management was provided. As a result of the activity, farmers experienced improved skills and convenience in processing palm sugar using modern tools such as a palm sap mixer and a palm sugar sieving machine. The processed products became cleaner, and the processing time was reduced from 5 hours to 3–4 hours, thereby accelerating production and improving output quality. Furthermore, there was a significant increase in farmers' knowledge of digital marketing strategies.

Abstract

The Mon Ikeun Village area in Aceh Besar is experiencing a clean water crisis due to a prolonged drought, which has significantly impacted human needs and necessitates identifying alternative water sources. This study aims to determine groundwater potential in the area using the Electrical Resistivity Tomography method. Data acquisition was conducted along three survey lines, each 420 m long. The Wenner-Schlumberger configuration was employed, using 22 electrodes with a spacing of 20 m. Data processing was done using ResIPy software to generate 2D resistivity cross-sections representing the subsurface structure. The resistivity sections were interpreted by correlating them with regional geological data and secondary data from wells located near the study area. The results indicate that two different lithologies dominate the subsurface structure of the study area. The first is a conductive zone with resistivity values of ≤316.23 Ω.m, interpreted as alluvium composed of clay, sand, and gravel. The second is a resistive zone with resistivity values of ≥562.34 Ω.m, interpreted as bedrock composed of limestone. Based on the subsurface lithology, zones with groundwater potential are found in conductive areas with resistivity values ranging from 3.16 to 56.23 Ω.m, which are associated with water-saturated alluvial layers, particularly those dominated by clay and sand. From the 2D resistivity cross-sections analysis, line 3 shows the highest potential for groundwater exploration, with water-saturated layers occurring at both shallow and deeper depths, reaching up to 0–40 m. This study provides valuable information for water resource management in Mon Ikeun Village, especially in addressing future clean water shortages.
