Abstract

Limbah tandan pisang banyak mengandung selulosa sebagai bahan baku dalam pembuatan asam oksalat. Pembuatan asam oksalat dari tandan pisang dilakukan melalui 4 tahapan yakni: hidrolisis, pengendapan, pengasaman, dan pengkristalan. Kandungan selulosa di dalam tandan pisang kepok kuning sekitar 35% dikonversi menjadi asam oksalat dengan hidrolisis alkali menggunakan KOH. Dalam proses hidrolisis ini menggunakan variasi konsentrasi KOH  5, 10, 15, 30, dan 40% dan waktu hidrolisis 60 menit, 75 menit, dan 90 menit. Dari  penelitian yang telah dilakukan diperoleh kadar maksimal asam oksalat dalam larutan hasil hidrolisis 45,04% dan rendemen 9,92% pada konsentrasi KOH 15% dan waktu hidrolisis 60 menit

Abstract

Heat transfer characteristics in rectangular with a sharp 180o turn have been examined experimentally using the naphthalene sublimation method. The sharp 180° turn was obtained by dividing a rectangular passage into two channels using a divider wall with a rounded tip at the location where the flow negotiates the turn. The channel cross-section (WxH) is 50×25 m, and three turn clearances of 30, 50, and 70 mm have been tested in this study. Local mass transferrates on all walls of the channel have been measured to clarify the heat transfer characteristics in the channel. The result indicated that the highest coefficient of heat transfer was achieved in the channel with turn clearances of 30 mm.Keywords: Heat Transfer Characteristics in Rectangular,Turn Clearances, Mass Transfers

Abstract

Tujuan penelitian ini adalah untuk mengidentifikasi hubungan stres kerja dan stres keluarga dengan kesehatan wanita di Indonesia. Studi ini merupakan cross-sectional terhadap 331 wanita menikah yang bekerja di 14 perusahaan manufaktur di Indonesia. Hasil penelitian ini membuktilan bahwa ada hubungan positif yang signifikan antara dukungan sosial dan PHS, tetapi hubungan negatif yang signifikan juga ditemukan antara PHS dan stres kerja serta stres keluarga. Analisis regresi berganda hierarki menjelaskan status kesehatan wanita bekerja yang sudah menikah dengan empat kategori: pribadi, terkait pekerjaan, terkait keluarga, dan dukungan sosial, dan menyumbang 45,4% dari varian. Ketika faktor terkait keluarga ditambahkan ke model, kekuatan penjelasan meningkat 17,9% dibandingkan dengan varians yang dijelaskan. Stres keluarga merupakan variabel utama tidak hanya untuk menjelaskan varians tetapi juga untuk berkorelasi dengan status kesehatan. Baik stres kerja dan stres keluarga harus dipertimbangkan bersama saat menangani kesehatan wanita yang bekerja di sektor industri di Indonesia.

Abstract

This study aims to determine the quality of physics concept understanding test items on the topic of electromagnetic waves based on estimation of item fit, item difficulty level estimation, and item reliability estimation. The research sample consisted of 298 eleventh-grade science students from several public high schools in Central Kalimantan province. The results of data analysis using the Rasch model with the aid of QUEST software showed that all items were fit or valid, with INFIT MNSQ values ranging from 0.77 to 1.33. The item reliability was 0.98, categorized as excellent, and the test participant reliability was 0.25, categorized as weak. The difficulty level of the test items was categorized into three: 5 items were difficult, 5 items were moderate, and 5 items were easy. Furthermore, based on the analysis using OUTFIT t values, one item was discarded and could not be used as a test instrument because it had an OUTFIT t value greater than 2.

Abstract

Wayang garing merupakan kesenian khas dari daerah Serang, Banten, namun mayoritas masyarakat masih belum mengenal wayang garing dengan baik. Wayang garing memiliki peran yang penting dalam menyebarkan pesan, sastra, nilai moral, dan pengetahuan di masyarakat Banten. Peran seorang dalang dalam mempopulerkan wayang garing sangatlah berarti, namun sedikit yang mengetahui tentang proses karir dan karya dari satu-satunya dalang wayang garing saat ini, yaitu Kajali. Popularitas wayang garing saat ini mengalami penurunan yang mengkhawatirkan, karena seni ini hanya dilakukan oleh satu dalang saja dan adanya variasi hiburan yang beragam. Oleh karena itu, perancangan media informasi, khususnya melalui website, sangatlah penting sebagai sumber informasi dan penghargaan terhadap keberadaan wayang garing. Tujuan penelitian ini adalah untuk merancang media informasi yang terstruktur berisi pengetahuan tentang wayang garing, dan diharapkan bahwa website ini dapat meningkatkan kesadaran masyarakat terhadap warisan budaya ini serta mendorong partisipasi dalam pelestarian dan pengembangannya.
