A procedure text is a text in the form of a series of instructions that explain how to do something structurally. The study was conducted to identify the use of active verbs in procedural texts made by seventh-grade students of Junior High School Muhammadiyah 8 Surakarta. The purpose of the research is to find the forms of the verbs contained in the procedure text and then classify them based on the type and describe the morphological process towards the formation of active verbs. This research is qualitative descriptive research by utilizing Miles and Huberman data analysis. The results showed that there were two kinds of verbs, namely transitive and intransitive active verbs. In addition, several types of morphological processes were found, namely affixation and reduplication, including the use of prefixes (me-), phoneme adjustment (N), prefixes (meNg-), and suffixes (-kan), suffixes (-i), confixes (meM-kan). ), confix (meN-kan), confix (meNg-i) and reduplication, namely the repetition of all basic forms.

One of the obstacles to melon cultivation is the availability of seeds and the high price of melon seeds. This condition causes the need to assemble superior melon varieties with the expected characters. This study aims to form a pure line of melon with certain superior characteristics and can be proposed as a new high-yielding variety in the open-pollinated category. The research was conducted at the Experimental Garden of the Agrotechnology Study Program, Faculty of Agriculture, Trunojoyo University, Madura, from September-December 2022. This study used a randomized block design method. The treatments used were nine pure lines of melon (PK-669, D-162, PK-361, PK-165, PK-114, D-029, D-5089, PK-211, and comparison). Each treatment was repeated three times, and each experimental unit consisted of 12 plants. Research data were analyzed using analysis of variance (ANOVA) and HSD test α = 0.05. The selection advancement was analyzed by comparing character data for each generation. The research showed that the results of the characterization of ten melon lines S0-S4 generation on the characters of fruit length, fruit diameter, flesh thickness, and melon fruit weight showed a decreasing trend in each generation. The S4 generation (9.17 °brix) in the character of the average sugar content there was an increase that was not significantly different from the S3 generation (9.03 °brix), while the number of seeds in each generation had an average value that was not significantly different but occurred an increase in the number of seeds in the S3 (372) and S4 (381) generations. An increase in one generation of the population in the linear regression equation is estimated to reduce the character of fruit length by 0.50 cm, fruit diameter by 0.465 cm, flesh thickness by 0.140 cm, fruit weight by 0.199 Kg, sugar content by 0.752 °brix, and a number of seeds by 5.4.

Characterization is the first step in breeding to obtain information about a plant's character. This study aims to determine the character of the hybrid melon candidate. The research was carried out in the experimental garden of the Agrotechnology Study Program, Trunojoyo University, Madura, from September to December 2021. The research used a randomized block design with treatment using six hybrid melon candidates (G1, G2, G3, G4, G5, and G6) and two comparison varieties (Envy and Action 434) with three replications. The results showed that Candidate G2 had higher values of fruit diameter, flesh thickness, number of seeds, and fruit weight than the two comparison varieties. The highest sugar content value is found in candidate G4, which is 13.80%. Heritability values in the broad sense of quantitative characters ranged from 0.62-0.98, and there were correlations between characters (positive and negative) between the observed characters.

In solving the problem of abrasion and also protecting marine ecosystems, it is necessary to come up with an idea, namely a wave energy retaining structure that is also capable of being a habitat for marine biota. Therefore, in this study, artificial coral reefs were tested which are considered capable to solve these problems, plus those which at the same time rehabilitate damaged coral reef ecosystems. The artificial reefs model in this test is a hexagonal type with one layer arrangement. To get the success value (K D ) of artificial reefs, it is seen from the percentage of damage caused by the influence of height and wave period. Then the K D value was calculated using the Hudson formula so that it was found that the hexagonal type artificial reefs had a K D value = 1.2.

The Indonesian Air Force is the main combat tool in the use of force to defend the sovereignty and territorial integrity of the Unitary State of the Republic of Indonesia as a unit in order to achieve guarantees for the safety of the nation and state. Indonesia only relies on 33 F-16 AM, BM, C and D aircraft, which are more than 30 years old. Then 16 Sukhoi 27 and 30 aircraft with almost 20 years of age as the main fighter aircraft. The limited number of aircraft spare parts as well as the limited types and number of guided missiles also caused the combat readiness of the F16 and Sukhoi 27 and 30 aircraft to be not optimal. The F5 Tiger fighter has fallen out of service in recent years and there has been no replacement to date. Likewise, the Hawk 100/200 aircraft which are more than 25 years old. the obligation of the Ministry of Defense to plan the purchase of fighter aircraft that will operate until 2030 and 2040. This research will use the Analytical Hierarchy Process (AHP) method to determine the choice of Combat Aircraft with predetermined criteria with the alternative choice of Dassault Rafale fighter aircraft from France, the Su 35 Russian-made and US-made F-15 EX aircraft. The highest data processing results are Dassault Rafale 63.7%, Su 35 20.3% and F-15 EX 16%. The result of the Multirole Combat Aircraft selection is that the Dassaut Rafale is selected. with an Inconsistency value of 0.04. This shows that the alternative calculation is still within the inconsistency threshold, which is 0.1. With the election of Dassault Rafale, it is hoped that the Transfer of Technology with PT.

Acne vulgaris or acne is a common inflammatory pilosebaceous condition that affects up to 90% of teenagers, begins during adolescent years, and often persists into adulthood. Acne vulgaris, especially on the face, has a major impact on the emotional, social and psychological health of patients. In treating acne, it is necessary to identify the exact type of acne. The manual method is considered less effective, so it is proposed an automatic method using a computer, which uses image processing techniques. This research was conducted to identify the types of acne on facial acne images. The methods used are K-Means Clustering for segmentation, Gray Level Co-occurrence Matrix (GLCM) for feature extraction, and Extreme Learning Machine (ELM) for classification. The dataset is 100 images and consists of 3 classes, namely Nodules, Papules and Pustules. Testing is done in two stages, namely testing 2 classes (Nodules and Papules), followed by testing 3 classes (Nodules, Papules and Pustules). Testing of 2 classes produces the highest accuracy of 95,24% and testing of 3 classes produces the highest accuracy of 80%.

Generally, the purpose of artificial reefs is to rebuild naturally occurring coral reefs that have been destroyed. Without sacrificing the attractiveness of the protected beach, these manmade reefs functioned as new habitats for marine life and protected coasts by reducing wave energy. on the other side man-made artificial reefs can perform as submerged breakwaters, their ability to dampen incoming waves must be investigated. In this paper, the researchers present a new shape in the form of a hexagonal artificial reef. The wave attenuation performance index is calculated using the wave attenuation performance rating. The research focuses on the effect of structural height (h/d) on transmission wave value using a physical testing method on a scale of 1:10 at the wave flume of the Department of Marine Engineering, Sepuluh Nopember Institute Technology, Surabaya. The test results indicate that the smallest transmission coefficient (KT) was produced on artificial reefs Configuration A-3 with the greatest submerged depth (h/d=0.75). The parameter results indicate that the greater the wave steepness (H/gT2) and the significantly larger the immersion depth (h/d), the better the wave reduction.
