Abstract

In the digital era, it is necessary to develop an online booklet on crystal guava pests and diseases. Pests and diseases are major constraints on agricultural productivity, disrupting plant physiology and growth, and thus reducing yields. The objective of this research is to develop an online booklet on crystal guava pests and diseases and how to manage them. Data collection was conducted through observation and interviews with owners and managers to obtain information on pests and diseases. Data were analyzed using descriptive qualitative methods. The study identified five pests of crystal guava: fruit fly (Bactrocera dorsalis), ladybug (Epilachna admirabilis), leaf caterpillar (Lepidoptera: Pyralidae), armyworm (Spodoptera litura), and mealybug (Paracoccus marginatus). The diseases identified were: Capnodium citri fungus (sooty mold), anthracnose disease (Colletotricum sp), red rust disease (Chephaleuros virescens), white fungus Fusarium sp, fruit rot disease (Botryodiplodia sp), and leaf spot disease (Cercospora psidii). Crystal guava care is carried out by maintaining garden cleanliness, adjusting plant spacing, fertilizing, spraying insecticides, setting fly traps, and wrapping young fruit. The conclusion of this research can be developed into a YouTube-based booklet as a guide for crystal guava farmers.

Abstract

The Ombilin Basin in West Sumatra is one of the oldest intermontane basins in Indonesia that has significant geological potential, especially in relation to coal content and possible petroleum systems. This study uses a three-dimensional gravity inversion method to model the distribution of subsurface density from a depth of 0 to 6000 meters. The purpose of this study is to examine the subsurface geological modeling in the Ombilin Basin and to be a reference in exploration geophysical studies in other basins in Indonesia that have similar characteristics. Corrected regional gravity data are used as input in the inversion process to reconstruct the relative density model of rocks. The inversion results show a low-density zone (Δg between -0.1995 to -0.0099 gr/cc) in the central and southwest parts of the basin associated with sedimentary deposits such as sandstone, shale, and coal. At depths of more than 4000 meters, a high-density zone is identified that reflects the presence of basement rocks or possible magmatic intrusions. This density distribution strengthens the understanding of the basin geometry and potential hydrocarbon traps. This study shows that the gravity inversion method is an effective and economical approach for subsurface geological interpretation, especially in areas with limited exploration data.

Abstract

Asam sunti is a traditional Acehnese seasoning made from dried bilimbi fruit (Averrhoa bilimbi L.). This study aims to examine the organoleptic characteristics, standard recipe, consumer acceptance, and shelf life of instant fried rice seasoning with the addition of asam sunti. A quantitative approach was employed using an experimental method. Data were collected through observation tests by five expert panelists (Culinary Arts Lecturers, Family Welfare Education Department, FKIP, Syiah Kuala University) and an acceptance test by 30 general consumer panelists. The results showed that the third treatment (BA3) had the best organoleptic characteristics in terms of color, aroma, texture, and taste, according to both expert and consumer panelists. The BA3 fried rice had a mocha-brown color, a spiced aroma, a savory taste, and a dry texture. The research hypothesis was accepted, as the addition of asam sunti had a significant effect on the organoleptic characteristics and consumer acceptance. Both expert sources and consumers favored the BA3 treatment because it provided a unique and appetizing traditional flavor. In conclusion, the asam sunti instant fried rice seasoning (BA3) has the potential to be developed as a practical, long-lasting, and widely favored Acehnese culinary product. This study employed a quantitative approach using an experimental method conducted at the Culinary Education Laboratory, Faculty of Teacher Training and Education (FKIP), Syiah Kuala University. The object of the study was fried rice with instant seasoning made from asam sunti. The subjects consisted of 4 expert panelists and 30 general consumer panelists. Data collection was carried out through organoleptic tests (color, aroma, texture, and taste) using a hedonic scale and consumer acceptance scale. The data were statistically analyzed using one-way ANOVA and LSD (Least Significant Difference) test at a 0.05 significance level with the assistance of SPSS software version 26.0. The results showed that the third treatment (BA3) produced fried rice with instant seasoning made from asam sunti that received the highest organoleptic scores in terms of color, aroma, texture, and taste. The BA3 recipe used a balanced composition of ingredients and spices, resulting in an appealing color, strong spiced aroma, dry texture, and savory taste favored by both expert panelists and consumers. Asam sunti instant fried rice seasoning (BA3) has the potential to be developed as a practical, long-lasting, and widely accepted Acehnese culinary product.
