<![CDATA[A barge loading conveyor (BLC) is the main means of transporting coal (material handling) from the stockpile to the barge. Disruption of the conveyor which is driven by an electric motor results in the cessation of the coal shipping process, so performance and efficiency in its use must be ensured. The purpose of this research is to see the value of overall equipment effectiveness (OEE) on PT Mitra Barito barge loading conveyor (BLC), which will later be used as a basis for corrective actions and efforts to increase productivity. The method used in this research is a quantitative method where at this stage the value of overall equipment effectiveness (OEE) is calculated which includes three categories of levels of availability, level of performance, and level of quality. Where in looking at the causes of low OEE seen from the proportion of six major losses. The results showed that the average overall equipment effectiveness (OEE) value of 56.19% was considered ineffective because corrective steps still needed to be taken so that it could inhibit barge loading conveyor (BLC) activities. This is affected by slowdowns, tuning, and adjustments, as well as idling and mining stops with high loss proportion values.]]>

<![CDATA[Learning activities in the Fundamentals of Photography course which have been running so far have experienced several obstacles including the absence of teaching materials specifically designed to be effective, efficient, and attractive in learning. Some basic photography material should be carried out in practice, but in reality, it must be delivered in theory given the limited time and learning resources and the low learning outcomes and results of student creativity in the field of photography which does not meet the standards for completeness assessment. To overcome these problems, competence-based and production-oriented digital teaching materials are developed which are valid and suitable for use in learning activities as well as for student self-study. This research is a type of development research using the Dick and Carey model with the final product being a digital textbook developed with the help of the Sigil application. The approach used is a competency-based and production-oriented learning approach. Before testing D3 Multimedia Computer STT STIKMA Internasional student, validation was carried out on material experts and media experts, which were then corrected according to the expert's assessment. Data from the trial results during implementation activities in learning were analyzed using descriptive statistics and questionnaire calculations from respondents using criteria from the Likert scale. Indicators of success and feasibility of measuring digital teaching materials are assessed from the feasibility of content, presentation of content, language, graphics, and assessment at the end of learning activities. The results of validation by experts and trials on students show that basic digital photography teaching materials have the feasibility and validity to be used as a supplement in facilitating student learning and practicum learning while taking photography basics courses.]]>

<![CDATA[Turmeric is a plant that is included in the spice plant category and is also a family medicinal plant (TOGA) which is good for health. However, in the drying process they still use the traditional method of drying in the sun, so this method is less effective because it has to depend on the weather. Therefore there must be a new innovation, namely using a dryer. In this study, the dryer used was an oven that had been designed using a hair dryer as the heat source. The purpose of this study was to determine the performance of the turmeric dryer with a hair dryer as a heat source. This type of research is a pure experimental research. The research object is an oven-shaped dryer that uses a hair dryer as a heat source. After conducting performance tests, the turmeric dryer can work well. This study uses 3 time variants, namely, 30, 60, and 90 minutes. Testing at 55°C was the most efficient time, namely 90 minutes with an initial weight of 200 grams to 118 grams which experienced higher shrinkage than 30 minutes and 60 minutes. The longer the drying time, the better the drying results.]]>
