Abstract

This study aimed to analyze the effectiveness of the smoking method using teak (Tectona grandis) wood waste in the agathis (Agathis sp) wood preservation process. The smoking process was done by putting teak wood waste into the combustion chamber and inserting agathis wood into the smoke room. The smoking duration was divided into 6 hours, 9 hours, and 12 hours with a maximum temperature ±70°C. The analysis carried out was an analysis of the chemical compound using GC-MS pyrolysis and testing the termite based on SNI 7207-2014. The results of GC-MS showed that the resin wood treated with smoking contained anti-termite compounds, namely phenolic, phenyl, and acid compounds, with the highest composition of 92.76% obtained from the duration of 12 hours of smoking. The termite test results showed that untreated wood had a higher weight loss and lower termite mortality than smoked wood. Meanwhile, the longer the smoking process, the lower the wood weight loss with the same mortality rate of 100%. It can be concluded that the smoking method using teak wood effectively increases the durability value of agathis against termites Coptotermes curvignathus.

Abstract

Preeklampsia adalah komplikasi kehamilan pada trimester 2 dan trimester 3 yang ditandai dengan hipertensi dan proteinuria yang terjadi setelah minggu ke-20 kehamilan. Invasi trofoblas pada arteri spiralis uterus dengan gejala klinis hipertensi, proteinuria dan edema, yang berasal dari perubahan patologis dalam vaskularisasi endotelium ibu atau mengakibatkan disfungsi endotel pada plasenta. Preeklampsia meningkatkan ekspresi molekul adhesi ICAM-1 pada permukaan sel endotel yang berinteraksi dengan ligannya pada permukaan leukosit. Munculnya sitokin inflamasi mengakibatkan peningkatan aktifitas makrofag dan netrofil pada pembuluh darah arteri spiralis sehingga akan mengakibatkan disfungsi endotel. Penelitian bertujuan untuk mengetahui adanya genotip gen ICAM-1 pada ibu preeklampsia dengan menggunakan metode Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). Penelitian ini merupakan jenis penelitian deskriptif laboratorium. Populasi dalam penelitian ini yaitu pada ibu preeklampsia yang berumur 26-40 tahun dengan usia kehamilan ≥ 20 minggu (Trimester 2 dan trimester 3) sebanyak 6 responden. Metode yang digunakan pada penelitian ini yaitu Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) dengan menggunakan enzim retriksi BstU1 (Bsh1236I). Berdasarkan hasil penelitian menunjukan bahwa hasil visualisasi tersebut dari 6 sampel pasien preeklampsia diperoleh hasil 4 positif (66%) yang menjadi gen ICAM-1. Hasil PCR dengan menggunakan serum pasien ibu preeklampsia adalah genotipe KK (100 %) ditandai dengan adanya hasil positif gen ICAM-1 pada 4 sampel dengan terbentuk pita DNA berukuran 223 bp dan setelah dilakukan digesti DNA dengan enzim retriksi BstU1 (Bsh1236I) ditemukan hasil membawa genotipe KK terbentuk pita DNA berukuran 223 bp (50%) dan genotipe EK terbentuk pita DNA berukuran 223 bp, 136 bp dan 87 bp (50%) yang menandakan adanya mutasi gen ICAM-1, sedangkan pada genotipe EE (0%). Kesimpulannya Polimorfisme gen ICAM-1 exon 6 pada serum pasien ibu preeklampsia dengan menggunakan enzim retriksi BstU1 (Bsh1236I) diperoleh hasil pita DNA yang berukuran 223 bp (KK) dan 223 bp, 136 bp dan 87 bp (EK) yang menandakan adanya mutasi gen ICAM-1.

Abstract

Early economic education plays an important role in shaping children's character, habits, and mindset in managing resources wisely. However, its delivery must be adapted to children's level of understanding so that basic concepts such as saving, cooperation, and distinguishing needs from wants can be grasped in a fun and meaningful way. This community service activity aimed to introduce fundamental economic concepts to elementary school students through a learning-by-playing approach. The activity was carried out by students of Universitas Muhammadiyah Makassar at a Muhammadiyah elementary school using interactive methods including economic material delivery, educational games, prayer practice, and social action. The results showed that this approach was effective in enhancing children's understanding and interest in basic economic concepts. The participants were enthusiastic, able to comprehend the material, and demonstrated behavioral changes, such as showing more appreciation for friends and understanding the importance of saving. The school welcomed the program positively and expressed hope for its continuation. Therefore, this fun and educational approach proved successful in fostering early economic literacy while simultaneously shaping positive character traits in children.
