Kawasan Pantai Pariaman Tengah memiliki potensi pada sektor pariwisata yang bernilai tinggi dengan jumlah pengguna layanan telekomunikasi yang semakin meningkat. Oleh karena itu, penting untuk menilai kualitas jaringan 4G LTE (Long Term Evolution) dari operator yang tersedia di kawasan tersebut. Penelitian ini dilakukan untuk menguji performasi kualitas jaringan pada tiga jenis operator, yaitu Telkomsel, XL Axiata, dan H3I dengan metode drive test yang menggunakan Iddle Mode dan software TEMS Pocket. Parameter kualitas jaringan yang dinilai adalah RSRP (Received Signal Reference Power), RSRQ (Received Signal Reference Quality), dan SINR (Signal to Interference and Noise Ratio). Adapun persentase yang termasuk dalam kategori diatas normal atau dalam range hijau dan biru dijumlahkan dan kemudian dibandingkan antara ketiga operator. Berdasarkan hasil analisis, jumlah persentase RSRP dari operator Telkomsel 80,87% vs XL Axiata 84,51% vs H3I 82,57%; persentase RSRQ dari operator Telkomsel 94,53% vs XL Axiata 91,62% vs H3I 99,78%; dan persentase SINR dari operator Telkomsel 39,63% vs XL Axiata 36,04% vs H3I 32,03%. Sehingga jika dibandingkan antara ketiga operator dapat disimpulkan bahwa nilai RSRP yang paling baik ditemukan pada operator XL Axiata, nilai RSRQ yang paling baik ditemukan pada operator H3I, sedangkan nilai SINR paling baik ditemukan pada operator Telkomsel.

The 2-18 GHz frequency band is a spectrum that is widely used for telecommunication systems, both military and civil. This is proportional to the number of illegal uses. This research develops an antipodal vivaldi antenna to support direction finding activities of illegal transmitters in the 2-18 GHz frequency band. Antenna design is a simulation using CST software by modifying the ground, widening the antenna arm, and increasing the length of the transmission line. The antenna design measures 94.14 x 73.2 mm on FR-4 substrate with a dielectric constant of 4.6 and a thickness of 1.6 mm. The simulation results show that the antipodal vivaldi antenna has a value -49.95378 dB ≤ S11 ≤ -10.022357 dB, 1.0066947≤ VSWR ≤1.9248251 and an average gain of 5.1558 dB in the 2-18 GHz frequency band.

The Voltage Standing Wave Ratio (VSWR) serves as a comparative measure between transmitter and receiver voltages, impacting site transmit power. VSWR values at a Radio Base Station (RBS) are evident in feeder cable losses, jumpers, combiners, and radio antenna losses. This study aims to assess the impact of poor VSWR values on BTS transmit power and perform troubleshooting analysis on 4G signal quality and Coverage Area. The study commenced with a literature review and VSWR measurements in the Gurun Laweh Aia Pacah region. The process involved identifying VSWR issues at the BTS site, conducting a Drive Test using pocket Tems, and troubleshooting the VSWR problem. Drive Test findings encompassed areas with weak signals, BTS site data, and problematic spots. The analysis utilized applications like Tems Discovery and MapInfo Pro. Results along the Gurun Laweh Aia Pacah road showed signal strength affected by a high VSWR value of 1.6. RSRP data rated 50% in the good category, SINR at 31% in the good category, and throughput at 5% in the good category. Elevated VSWR values diminish signal range, subsequently impacting traffic metrics. Immediate VSWR troubleshooting becomes imperative; low VSWR promotes higher transmit power efficiency, while normal VSWR ensures optimal transmit power efficiency.

Nagari Sumanik merupakan salah satu nagari yang berada di Kecamatan Salimpaung, Kabupaten Tanah Datar, Provinsi Sumatra Barat. Sebagian besar penduduk berprofesi sebagai petani. Selain mendampingi kaum laki-laki dalam bertani, kaum perempuan juga banyak yang berprofesi sebagai penjahit dan buruh jahit sulaman kepala peniti. Setelah pandemi Covid-19, pendapatan yang diperoleh oleh penjahit dan buruh jahit menurun drastis. Sementara orderan jahitan sepi, dirumah mereka juga tersedia banyak limbah sisa jahit, seperti sisa kain, sisa benang maupun kancing. Limbah jahit ini jika tidak dimanfaatkan ini akan menjadi sampah. Untuk mengatasi permasalahan ini akan dilakukan dua hal yang utama : membuka cakrawala mitra tentang hal-hal yang lebih kreatif bernilai guna dengan menggunakan teknik dasar menjahit dan memberikan contoh keterampilan yang dapat dibuat dengan memanfaatkan limbah jahit tersebut dan dikreasikan dengan teknik sulaman kepala peniti. Untuk membuka cakrawala dan menambah pengetahuan dapat diberikan dengan memaparkan tentang penggunaan internet untuk mencari ide yang kemudian dapat juga digunakan untuk memasarkan produk. Mudahnya mendapatkan informasi melalui media internet, diharapkan dapat membuka cakrawala para wanita untuk lebih mengembangkan potensi yang ada. Sedangkan untuk contoh keterampilan tim PKM melakukan workshop keterampilan membuat aksesoris handmade dengan menggunakan bahan baku utama kain perca. Pembuatan aksesoris dengan kain perca ini juga menggunakan teknik jahit sulaman Dengan adanya keterampilan ini diharapkan nanti bahwa mitra dapat memanfaatkan semua potensi yang ada untuk meningkatkan ekonomi kreatif masyarakat. Hasil dari keterampilan ini dapat dipakai sendiri, dijual secara pribadi atau kelompok, dijadikan souvenir khas dari Nagari Sumanik.
