Judul: Aplikasi pati singkong sebagai bahan baku edible coating untuk memperpanjang umur simpan pisang cavendish (Musa cavendishii)
Abstrak: Bahan makanan pada umumnya sangat sensitif dan mudah mengalami penurunan kualitas karena faktor lingkungan, kimia, biokimia, dan mikrobiologi. Penurunan kualitas dan adanya proses hidup setelah panen tersebut dapat dipercepat dengan adanya oksigen, air, cahaya, dan temperatur. Salah satu cara untuk mencegah atau memperlambat fenomena tersebut adalah dengan pengemasan yang tepat. Edible coating berbasis pati singkong dapat diaplikasikan untuk melapisi buah pisang cavendish yang utuh sehingga dapat mempertahankan kecerahan warna dan dapat mempertahankan umur simpan. Lapisan film yang dibentuk memiliki pori-pori yang lebih kecil sehingga laju transmisi terhadap uap air dan gas juga rendah.

Judul: Application of KMnO4-Based Ethylene Adsorber
Active Packaging in Cavendish Banana Distribution Packaging (Case Study of PT
XYZ)
Abstrak: Pisang merupakan salah satu produk holtikultura dengan potensi besar untuk dikembangkan dan memilki nilai ekonomis yang tinggi. Namun, pisang termasuk dalam buah klimakterik yang memiliki tingkat respirasi dan produksi etilen tinggi setelah masa panen sehingga berdampak pada umur simpan yang singkat. Hal ini menjadi tantangan signifikan bagi distributor, karena dapat menghambat jangkauan distribusi dan meningkatkan resiko kerusakan buah sebelum mencapai konsumen akhir. Upaya untuk mempertahankan kesegaran produk selama proses distribusi dan transportasi adalah dengan penggunaan teknologi kemasan aktif penjerap etilen. Bahan penjerap berbasis KMnO4 dengan media arang aktif bekerja dengan menjerap etilen yang diproduksi oleh buah dan mengoksidasi etilen sehingga menghambat proses kematangan. Bahan aktif perlu dikemas agar tidak terjadi kontak langsung dengan produk pangan karena bersifat toksik sehingga dapat merusak mutu buah. Penelitian bertujuan mengidentifikasi karakteristik material kemasan dengan pengujian sifat fisik dan mekanis meliputi gramatur, densitas, indeks tarik dan regangan putus, dan ketahanan gesek. Serta analisis fisik mutu buah untuk mengetahui pengaruh kemasan aktif selama penyimpanan yaitu dengan uji warna dan umur simpan berdasarkan tingkat kematangan. Hasil pengujian diperoleh bahwa material litho paper lebih baik sebagai wadah pembungkus untuk bahan penjerap etilen dibandingkan meltblown nonwoven karena memilki nilai kekuatan yang lebih tinggi, resiko kebocoran rendah, dan nilai estetika yang terjaga. Perlakuan terbaik dalam mempertahankan kualitas mutu buah yaitu diperoleh pada pengemasan litho paper dengan penyimpanan suhu optimal mampu memperlambat proses degreening dan meningkatkan umur simpan buah pisang Cavendish menjadi 6 hari penyimpanan dibandingkan kontrol hanya bertahan 3 hari., Bananas are one of the horticultural products with significant potential for development and high economic value. However, bananas are classified as climacteric fruits, which have high respiration rates and ethylene production after harvest, resulting in a short shelf life. This poses a significant challenge for distributors as it can hinder distribution reach and increase the risk of fruit damage before reaching the end consumer. Efforts to maintain product freshness during distribution and transportation involve the use of active packaging technology to absorb ethylene. KMnO4-based absorbents with activated carbon media work by adsorbing the ethylene produced by the fruit and oxidizing it, thereby inhibiting the ripening process. The active material needs to be packaged to prevent direct contact with food products due to its toxic nature, which could degrade fruit quality. The research aims to identify the characteristics of packaging materials by testing their physical and mechanical properties, including grammage, density, tensile strength and elongation at break, and friction resistance. Additionally, the physical quality of the fruit is analyzed to determine the impact of active packaging during storage through color testing and shelf life based on ripening stages. Test results indicate that litho paper is superior as a wrapping container for ethylene absorbents compared to meltblown nonwoven, due to its higher strength, lower risk of leakage, and maintained aesthetic value. The best treatment for preserving fruit quality is achieved with litho paper packaging under optimal storage conditions, which can delay the degreening process and extend the shelf life of Cavendish bananas to 6 days compared to the control, which only lasts 3 days.

Judul: Perilaku Remaja dalam Mendengarkan Radio Komunitas (Kasus Pendengar BeTe Radio di Kelurahan Tegal Gundil, Kecamatan Bogor Utara, Kota Bogor, Provinsi Jawa Barat)
Abstrak: This research aimed to analyze the relation between teenager behaviors on community radio listening activity. This research goals are (1) to identify the pattern of listening activity on community radio among teenager (2) to analyze the relation between listeners characteristics and broadcast format assessment by listening community radio (3) to analyze the relation between community radio listeners pattern with the teenager behaviors, and (4) to identify the listeners expectations towards community radio. The main method of this research is quantitative approach, and qualitative approach as supporting. Research and observationshow that the teenagers who are listening to the BeTe community radio have low level of listening activity pattern. Affective level and social network were also relatively low. Related to the listeners characteristics, the research result showed that gender does not have any relation with the pattern of radio listening activity. Beside that, age, media ownership, and main activities have significant relation towards pattern of radio listening activity. To assess broadcast format variable, pshycological proximity does not have any relation significantly with the pattern of radio listening activity. In the pattern of radio listening activity variable which is consist of listening frequency, listening duration, program choices, participation on the program have significant relation with to point of view, affective, and social network of BeTe Radio listeners.
