Salah satu metode untuk menghitung dosis radiasi yang dihasilkan oleh linac adalah dengan menggunakan program simulasi MCNPX. Tujuan penelitian ini adalah untuk menentukan karakteristik kurva Percentage Depth Dose (PDD) untuk berkas sinar-x 6 MV dan faktor koreksi dari distribusi dosis akibat adanya ketidakhomogenan jaringan tubuh. Penelitian ini menggunakan fantom jenis ORNL-MIRD phantom (1996 version) yang telah dimodifikasi. Fantom dibedakan menjadi fantom homogen yaitu dengan komposisi air dan jaringan lunak dan fantom nonhomogen dengan komposisi jaringan lunak yang didalamnya terdapat organ paru-paru pada kedalaman 5-14 cm dan jaringan lunak yang didalamnya terdapat organ tulang belakang pada kedalaman 5-10 cm. Luas lapangan penyinaran radiasi 10 x 10 cm2 dengan arah penyinaran radiasi Anterior-Posterior (AP) serta Posterior-Anterior (PA) dengan SSD 100 cm. Dalam penelitian ini didapatkan karakteristik kurva PDD yang sama antara fantom dengan komposisi air dan fantom dengan komposisi jaringan lunak yaitu dosis maksimum berada pada kedalaman 1,5-2,0 cm. Pada fantom nonhomogen yaitu jaringan lunak yang terdapat organ paru-paru mengalami peningkatan dosis dengan deviasi tertinggi sebesar 49,748 % dan keberadaan organ tulang belakang mengalami penurunan dosis dengan deviasi tertinggi sebesar 31,044 %. Rentang faktor koreksi akibat adanya organ paru-paru adalah 0,701-1,663 sedangkan akibat adanya organ tulang belakang adalah 0,586-0,983.

Budidaya ternak lele merupakan salah satu kegiatan yang dilakukan kelompok tani muda untuk meningkatkan penghasilan. Budidaya lele dalam kolam terpal terbilang inovasi baru dan belum terlalu dikenal oleh masyarakat Dusun Bulu. Tujuan dari pengbadian ini adalah meningkatkan produktivitas ikan lele yang dibudayakan dalam lahan yang lebih sempit. Metode yang digunakan pada pengabdian ini adalah dengan pendampingan selama sekitar 1 bulan meliputi identifikasi masalah dan membuat rencana kerja, pembuatan pakan lele, serta sosialisasi dan evaluasi. Hasil program abdimas ini antara lain terbentuknya rencana kerja, pembuatan pakan lele 30 kg, serta terlaksanakanya penyuluhan dimana peserta dapat mengaplikasikan pembuatan pakan lele untuk budidaya lele terpal. Manfaat untuk dampak sosial dan ekonomi adalah pemanfaatan limbah rumah tangga organik sebagai bahan pakan lele yang lebih terjangkau. Tertundanya kegiatan abdimas di awal adalah karena wabah antrax, sehingga akses masuk ke Dusun Bulu dibatasi untuk warga luar. Meski demikian, peserta abdimas memiliki semangat dan motivasi yang tinggi untuk belajar membuat pakan lele, sehingga kegiatan dapat terlaksana dengan baik hingga akhir. Kata Kunci: Budidaya Lele, Kolam Terpal, Pakan Lele, limbah rumah tangga.

This research aims to reveal the relationship between gender stereotype perceptions and students' self-presentation at SMA Negeri 1 Muaro Jambi. This research is limited only to gender stereotyped views of students' daily life at school. This type of research is quantitative research with correlational methods. The sample in this research was students in classes X and The instruments used were gender stereotype questionnaires and student self-presentation questionnaires. Data were analyzed using the Percentage Test with formula C, statistical assumption test, and Correlation Test. The research results show that: 1) the level of perception of gender stereotypes of students at SMA Negeri 1 Muaro Jambi is in the high category with a percentage of 78%. 2) students' self-presentation at SMA Negeri 1 Muaro Jambi is in the high category with a percentage of 74%. 3) The research results also show that the correlation results are known to be positive at 0.414 > r table 0.138 with a sig result of 0.000 < 0.05. The Pearson correlation value obtained is interpreted using correlation guidelines, where the calculated r (0.414) is in the range (0.40 – 0.70) which is interpreted as falling into the category of having an adequate relationship. So it can be concluded that there is a significant relationship in the positive direction between perceptions of gender stereotypes and students' self-presentation.

Kulon Progo Regency still depends on Magelang and Klaten to meet its functional food needs for sweet corn cobs. The Migunani Women's Farmers Group (KWT) has high potential for developing food crops. With the large area of land owned and the Angora group which is still relatively young. The method used in this service is socialization and mentoring. The result of this service is an empowerment program through the development of sweet corn plants in the Migunani Women's Farmers Group (KWT), Nanggulan, Kulon Progro which has succeeded in increasing corn production. With the support of socialization and mentoring, it is hoped that this program can continue and become a model of empowerment for other farmer groups in the Kulon Progo region.

This research aims to calculate thoroughness among data points and analytical simulation curves in discussing corona discharges' (I-V) characteristics. The electrode construction used is the twin towers with dividing angles to the plane (TTDA-P) model in air, with negative DC polarity. An asymmetrical electrical CCP model in the electrode design uses research variations, including active electrode center clamp angles of q = 300, 450, and 600 and active and passive electrode distances (d) of 0.002 m, 0.005 m, and 0.008 m. The simulation curve comes from the analytical formulation of the reduced capacitance type (inserting a multiplying factor k to the sharp corners of the active electrode), with the simulation program being a Python GUI program. The experimental results produced an appropriate error value (t-test value £0.05) and a high percentage of tangent points value. The best curve was achieved at q = 450 and d = 0.008 m, with a t-test value of 0.0313 and the highest percentage of significant tangent points of 92.31%. For all variations q, there is a tendency that the smaller the value of d (the gap length among two electrodes), the greater the deviation distance between the simulation curve and the data points.
