Abstract

Abstrak Cable spacer merupakan isolator pasang luar berbahan polimer yang masih jarang digunakan di Indonesia. Isolator pasang luar rentan terhadap pengaruh lingkungan seperti kelembaban sehingga dapat mengurangi unjuk kerja dari isolator seperti penurunan tahanan permukaan yang mengakibatkan peningkatan arus bocor permukaan. Hal inilah yang mendasari dilakukannya penelitian mengenai pengaruh kelembaban terhadap karakteristik arus bocor  dari isolator cable spacer. Untuk memahami karakteristik arus bocor pada cable spacer, dalam penelitian ini dilakukan pengukuran dan pemodelan rangkaian ekivalen dengan menggunakan perangkat lunak ATP/EMTP. Selain itu juga dilakukan pemodelan matematis menggunakan perangkat lunak MATLAB. Untuk validasi, gelombang arus bocor hasil simulasi dibandingkan dengan hasil pengukuran. Variabel yang dibandingkan  adalah amplitudo, spektrum harmonik, urutan harmonik dominan dan nilai THD gelombang arus bocor. Hasil pengukuran menunjukan bahwa pada kondisi basah isolator cable spacer menghasilkan nilai arus bocor lebih besar daripada kondisi kering dengan kenaikan 34%. Arus bocor meningkat seiring dengan kenaikan tegangan. Perbandingan gelombang hasil pemodelan dan pengukuran  menunjukan hasil yang hampir sama. Untuk simulasi ATP selisih nilai rata-rata amplitudo sebesar 14% dan THD sebesar 0,33%. Sedangkan untuk simulasi MATLAB selisih nilai rata-rata amplitudo sebesar 47% dan THD sebesar 15%.               Kata Kunci : isolator pasang luar, arus bocor, isolator cable spacer .  Abstract Cable spacer is a polymer outdoor insulator that rarely used in Indonesia. Outdoor insulators may severe environmental influences such as humidity that reduce the performance of  insulator, decrease of surface resistance that cause an increase in surface leakage current. Therefore the influence of humidity on the leakage current characteristic of cable spacer needs to be investigated. To understand the characteristics of the leakage current, we tested and modeled the equivalent circuit using ATP / EMTP software and mathematical modeling using MATLAB software. For validation, we compared the leakage current waveform resulted in the simulation the test results. Variables that compared are the amplitude, harmonic spectrum, the dominant harmonic sequence and wave leakage current THD value.The test results showed that in wet conditions, cable spacer insulating material generated leakage current value greater than the dry conditions with a 34% increasing. Leakage current increased along with voltage increasing. Comparison between modeled results wave and the test results showed that the value was almost the same. For ATP simulation the difference average value of the amplitude was 14% and THD was 0.33%. While, for MATLAB simulation the difference between the average value of the amplitude was 47% and THD .was 15%. Keywords: outdoor insulators, leakage current, cable spacer insulator

Abstract

Implemented since 2007, The Indonesian Conditional Cash Transfer (PKH) program aims to alleviate poverty by encouraging education participation among the impoverished. Analyzing the educational expectations of PKH beneficiaries is crucial for program’s impact evaluation. Changes in educational expectations indicate the awareness of poor families to invest in education. Moreover, examining socio-economic impacts on educational expectations offers insights into challenges faced by impoverished families. This study, conducted on Tabuan Island in Tanggamus Regency which is a remote area with inadequate educational facilities, investigates the impact of PKH over 15 years by 2022. Using primary data from two groups: PKH beneficiary families (intervention) and non-PKH families (control) – the research quantitatively compares their educational expectations. Further exploration involves logistic regression tests to examine socio-economic factors’ influence on the intervention group. Results reveal PKH’s positive impact on elevating beneficiary families’ educational expectations. The analysis showed significantly higher educational expectations among PKH families compared to non-PKH families, particularly when excluding other educational assistance. PKH beneficiaries are estimated to be 10,269 times more likely to expect their children to graduate from college than non-PKH families. Internet access in the last 3 months, and participation in P2K2 counseling, have a positive impact on the PKH beneficiary families’ educational expectations. This highlights the importance of positive educational information and the potential of information technology in supporting their children’s education. However, it is concerning that despite having high expectations, families receiving PKH on Tabuan Island face challenges in ensuring their children’s access to college education.

Abstract

Masalah kesehatan jiwa akan menyebabkan penderitaan berkepanjangan baik bagi individu, keluarga maupun masyarakat. Fenomena  mental disorder atau gangguan jiwa terus meningkat secara signifikan. Pendekatanmanajemenpelayanan kesehatan jiwa berbasis komunitas (CMHN) ini salah satunya dengan pemberdayaan masyarakatmelaluikader kesehatan. Tujuan penelitian mengetahui pengetahuan kader kesehatan jiwa tentang TAKstimulasi persepsi mengontrol halusinasi di Wiayah UPTD Puskesmas Sukorejo Kota Blitar.Desain penelitian adalah deskriptif. Populasi penelitian seluruh kader kesehatan jiwa.Sampel penelitian sejumlah 29 kader dengan teknik total sampling. Pengumpulan data menggunakan kuesionerHasil penelitian sebagian besar 52%   memiliki pengetahuan kurang, 41% memiliki pengetahuan cukup, 7% memiliki pengetahuan baik.hal ini dikarenakan kader kurang mengetahui kegiatan TAK stimulasi persepsi mengontrol halusinasi,juga belum tahu tujuan mengontrol halusinasi dengan menyusun jadwal kegiatan.kader juga belum mampu mengaplikasikan TAK stimulasi persepsi mengontrol halusinasi pada sesi 2 dengan menghardik, melakukan kegiatan sesi 3, dan mengaplikasikan tahap kerja pada sesi 5,diharapkan Dinas Kesehatan atau Puskesmas untuk terus memberikan pelatihan dan pendidikan maupun kegiatan studi kasus sehingga pengetahuan kader akan menjadi lebih baik.
