Abstract

The main problem of adolescent reproductive health (KRR) in Indonesia, is the lack of information on reproductive health, the problem of shifting adolescent sexual behavior, poor health services and unsupportive legislation. The problem of adolescents in the Bandar Khalifah Health Center Work Area is that there are 103 teenagers who dropped out of school because of early marriage. The purpose of this study was to analyze factors related to adolescent knowledge about reproductive health at Gema Buana High School, with a correlation analytic research design.The population and sample were 72 high school students. The results showed that there was a relationship between the role of parents (p = 0.012), the role of peers (p = 0.000) and sources of information (0.030) with adolescent knowledge about reproductive health. For this reason, it is suggested to Gema Buana High School to establish PIK-KR as a means for students to gather information about reproductive health.

Abstract

Daging sangat rentan terhadap pembusukan atau penurunan kualitas. Penggunaan pengawet daging yang berbahaya seperti formalin di masyarakat merupakan hal yang dianggap wajar. Ditambah lagi penggunaan kantong plastik sebagai kemasan daging memperparah keadaan tersebut karena sifat kantong plastik yang cenderung toksik dan off flavour serta non-biodegradable. Oleh karena itu, diperlukan solusi untuk mengawetkan daging yang aman dan ramah lingkungan. Edible coating adalah teknologi sederhana dimana lapisan tipis komponen dimakan dan bertindak sebagai penghalang fisik terhadap karbon dioksida, oksigen, aroma dan gerakan kelembaban.Daun jati dipercaya memiliki sejumlah metabolit sekunder yang menjadikannya sebagai anti oksidatif. Chitosan banyak digunakan pada edible coating sebagai agen antimikroba. Oleh karena itu, produk organic film chitosan-ekstrak daun jati hadir sebagai preservatif alami daging yang aman dan ramah lingkungan. Teknik produksi dilakukan melalui uji laboratorium terlebih dahulu. Kemudian, produksi dengan bahan-bahan yang aman, berkualitas dan mudah didapatkan serta diolah secara higinis dengan teknologi pembuatan edible coating. Produk dikemas menggunakan aluminiumfoil klip dengan identitas produk berupa sticker. Promosi dilakukan secara online dan offline meliputi pembuatan akun media sosial, leaflet maupun tester produck. Akhirnya, berhasil menjual 30 kemasan dengan BEP 75,51%. Hasil tersebut berpotensi untuk dikembangkan pada kemasan yang lebih modern, perluasan pemanfaatan produk, perluasan distribusi di pasar modern, dan pengembangan usaha ditingkat usaha menengah keatas.

Abstract

Wirasangka mango is the identity flora of Tegal Regency. The morphological characters of the wirasangka mango have been studied, but need to be supplemented with anatomical characters. The anatomical character of the plant that needs to be studied is the anatomy of the leaves. Leaves have varying tissue structures and pigment content. This study aims to describe the anatomical characters and analyze the pigment content of wirasangka mango leaves. The characteristics and pigment content of wirasangka mango leaves have never been reported. Anatomical characters of mango wirasangka leaves were determined by cross-sectional leaf preparations using non-embedding method and whole mount leaf preparations. The pigment content of mango wirasangka leaves was analyzed using a spectrophotometer. The results of the study of the anatomical characters showed that the leaves of wirasangka mango have dorsiventral and hypostomatous leaf, have a palisade ratio of 4-5 cells, stomata are anomocytic type, guard cell length is 11.45 µm and guard cell width is 4.78 µm, and has a stomatal density of 173.25 /mm2. The chlorophyll content of shoots, young and mature leaves of wirasangka mango were 9.1 mg/l, 12.28 mg/l and 47.89 mg/l. The carotenoid content of shoots, young leaves and mature leaves were 293.51 µmol/g, 371.76 µmol/g, and 1445.88 µmol/g respectively, and the anthocyanin content of shoots, young leaves and mature leaves were respectively also 1.36 mg/100g, 0.75 mg/100g, and 0.38 mg/100g. The results of the research can be used to complete the characters that need to be observed in the characterization of wirasangka mango.
