argo ryan prayoga suyitno — 2025-12-12

Medicinal plants have been known to Indonesian people since ancient times and have become a very important addition to supporting human survival. In general, medicinal plants can be planted in rice fields or fields, in the highlands and lowlands. The conditions needed for chili plants to grow well are soil height, soil type, water, air temperature and humidity.
Humidity can be in the form of humidity in the air or soil moisture. Modifying the microclimate around chili plants is an effort so that cultivated plants can grow and develop well. Air and soil humidity, air and soil temperature are microclimate components that greatly influence plant growth, and each is related to creating optimal environmental conditions for plants. Soil moisture can affect the growth of medicinal plants. Soil moisture corresponding to the characteristics of medicinal plants is around 69.2%, 69.6%, 70.3% and 70.8%. The optimal air temperature for medicinal plants is 25-30°C. The lower the soil and air humidity, the growth of medicinal plants will not be optimal, the plants will experience stunting and the higher the soil moisture level and the higher the air temperature, the more medicinal plants will wilt.
In designing this monitoring, the author uses fuzzy logic to support detection accuracy in soil and air monitoring in medicinal plant cultivation. Fuzzy logic is a calculation method that uses linguistic variables or words, as an alternative to calculations using numbers. Meanwhile, in previous studies, researchers did not use a fuzzy logic system to support detection accuracy in soil and air monitoring in medicinal plant cultivation.

Efektivitas Model Level-Based Mission untuk Pembelajaran Huruf Hijaiyah

Nadila Shifa Auria — 2025-12-12

Learning basic Hijaiyah letters often faces challenges in maintaining student attention, especially with conventional methods that are repetitive and verbal in nature. Although game-based learning has been widely adopted, most are still stuck with simple quiz mechanics that do not facilitatea gradual learning structure (scaffolding). This study aims to analyze the Level Based Mission model in an educational survival horror game titled "Jejak Hijaiyah: Perisai Ayat dan Sang Penjelajah" (Traces of Hijaiyah: Shield of Verses and the Explorer). The method used is a qualitative descriptive analysis of the game design document by comparing it with Cognitive Load theory and the principle of Chunking. The analysis results show that the mission structure, which divides the 28 Hijaiyah letters into 7 levels (4 letters per phase), fulfills the principle of progressive mastery, where the cognitive load of students is managed gradually. In addition, the maze exploration mechanism and reward system in the form of “area purification” offer a stronger active discovery learning approach compared to the typical drag-and-drop model. The conclusion of this study suggests that the leveled mission model in the survival genre can be an effective alternative to improve memorization retention through emotional engagement and a systematic learning structure.
