Abstract

Penelitian ini memanfaatkan limbah kulit buah kakao sebagai bahan baku pembuatan papan partikel. Untuk memperbaiki sifat fisis dan mekanis dari papan partikel ini, ditambahkan batang kayu jabon yang berperan sebagai penguat. Pabrikasi papan partikel berukuran 30 cm x 30 cm x 1 cm diawali dengan pencampuran bahan baku, urea formaldehyde (UF), parafin, dan katalis. Kemudian bahan-bahan tersebut di kempa dengan tekanan 30 N/cm2 pada suhu 150°C selama 8 menit. Dilakukan 7 variasi komposisi massa antara kulit buah kakao dan batang kayu jabon secara berturut-turut adalah 100:0, 90:10, 80:20, 70:30, 60:40, 50:50, dan 0:100. Papan partikel diuji melalui uji fisis yaitu kerapatan, kadar air, pengembangan tebal dan uji mekanis yaitu modulus of elasticity (MOE), modulus of rupture (MOR), internal bond (IB), kuat pegang sekrup. Hasil pengujian papan partikel mengacu pada standar JIS A 5908:2003. Berdasarkan hasil yang diperoleh, nilai kerapatan sudah memenuhi standar dengan interval nilai 0,760 g/cm3 sampai 0,855 g/cm3. Setelah penambahan batang kayu jabon, sifat fisis dan mekanis mengalami peningkatan kualitas dibandingkan dengan papan partikel tanpa batang kayu jabon. Nilai kadar air dan pengembangan tebal menurun seiring dengan penambahan penguat. Begitu juga dengan nilai MOE, MOR, IB, dan kuat pegang sekrup semakin meningkat saat kuantitas penguat semakin banyak.Kata Kunci : batang kayu jabon, kulit buah kakao, papan partikel, dan penguat.

Abstract

Current family planning programs are urgently needed to prevent unwanted pregnancies and to improve the health and well-being of mothers and children. One of them is the IUD is a long-term contraceptive method that has a high level of effectiveness. The IUD is the third most commonly used method in Asia. This study aims to determine whether there is a relationship between education and work of women of childbearing age with the use of IUDs at the Temandang Health Center, Merakurak Subdistrict, Tuban . This research was conducted in July 2022 at the Temandang Health Center. This research methodology uses observational analytic with cross sectional design. The independent variables are education and work, while the dependent variable is IUD use. The population in this study were all active family planning acceptors at the Temandang Merakurak Health Center, a sample of 177 family planning acceptors was obtained using simple random sampling technique. Data processing used the chi square test with a significance level of <0.05. The results of the study of 177 female respondents of childbearing age, half of them had low education, almost all of them did not work and were not IUD acceptors. After statistical test using SPSS ρ -value 0.000, then H₀ is rejected. This proves that there is a relationship between education and occupation of women's reproductive organs with the use of IUDs at the Temandang Health Center, Merakurak Subdistrict, Tuban . The results of this study can provide input and information from several supporting factors that influence a woman of childbearing age following the family planning program so that health workers can optimize health promotion for couples of childbearing age in choosing the most appropriate contraceptive according to their needs and conditions.
