Abstract

Curcumin (diferuloylmethane), the primary bioactive compound in turmeric (Curcuma longa), is a natural polyphenol with proven pharmacological properties. Its safety and biodegradability, along with multifunctional health benefits, have been well-documented. However, curcumin exhibits poor water solubility. Consequently, curcumin shows low systemic bioavailability and rapid urinary excretion. A carrier matrix is essential to improve bioavailability and prolong systemic retention of curcumin, and one of carrier matrix that can be utilized is a bead matrix. In this study, bead matrices were prepared by combining a chitosan solution with lauric acid and carrageenan solutions and then dropping the mixture into a sodium hydroxide solution, which acts as an ionic neutralizing agent during bead formation. The encapsulation process was conducted by immersing the formed bead matrices in curcumin and glutaraldehyde solutions to facilitate crosslinking reactions with chitosan. The resulting bead matrices were analyzed using FT-IR spectroscopy to determine the interactions and bonds formed between the materials used. The results indicated that the encapsulation efficiency of curcumin was influenced by the concentrations of chitosan and lauric acid, with higher concentrations of both components leading to increased encapsulation efficiency.

Abstract

Indonesia faces dual challenges in the form of high dependence on coal and increased volumes of leaf and ranting organic waste. This study studied the development of biomass pellets from leaf litter and ranting as renewable energy (EBT) initiated by PT Building Solutions Indonesia (SBI) Cilacap together with Cilacap State Polytechnic. Analysis includes technical concepts, environmental impacts through a life cycle approach, as well as implementation potentials and challenges. Results show the use of biomass pellets can decrease net greenhouse gas and methane gas emissions from leaf burning and ranting by the community, as well as supporting the circular economy model. The main challenges include production energy consumption and particulate emission control. The concept is technically and ecologically feasible with optimization and policy support as a prerequisite for commercialization.

Abstract

The rotary dryer is a machine designed to simplify the cocopeat drying process. The current process still relies on sunlight; this drying process has the drawback of longer drying times and uncontrolled moisture content. The maximum moisture content of the cocopeat must be 15%. This research method is an experiment using several parameters: a drum speed of 6 rpm, heating temperatures of 600°C, 900°C, and 1300°C, with varying drying times of 120 and 150 minutes. The drying process at a temperature of 600 °C resulted in a decrease in humidity efficiency of up to 56.7% with a water content value of 23.8% in 150 minutes and a mass of 3.7 kg. Meanwhile, for drying at a temperature of 1300 °C, the best reduction in efficiency was obtained compared to the previous temperature, a decrease in water content of up to 84% with a water content value of 8.55 and a mass of 2.7 kg using a time of 150 minutes.

Abstract

Politeknik Negeri Cilacap sebagai Perguruan Tinggi Negeri tunggal di Kabupaten Cilacap menjadikannya Perguruan Tinggi pilihan favorit masyarakat Cilacap dengan jumlah mahasiswa pertahun yang terus bertambah sehingga dengan sendirinya menuntut ruang parkir yang cukup. Permintaan parkir yang melebihi kapasitas parkir yang tersedia dan terhambatnya manuver kendaraan menyebabkan tertundanya pengunjung yang akan parkir sehingga dapat memicu adanya parkir di bahu jalan.. Penelitian ini bertujuan untuk mengetahui kelayakan tempat parkir di Gedung Kuliah Bersama Politeknik Negeri Cilacap sehingga dapat menjadi bahan evaluasi dalam mengoptimalisasi ruang parkir yang ada sehingga menjadi lebih baik lagi. Metode penelitian yang digunakan yaitu survey pengamatan lapangan dan kuesioner. Berdasarkan hasil penelitian menunjukan bahwwa kapasitas parkir pada hari puncak tidak memenuhi syarat yang dtunjukan dengan jumlah kendaraan yang parkir per jamnya melebihi kapasitas parkir yang ada. Indeks parkir (IP) > 1 artinya kebutuhan parkir masih diatas daya tampung sehingga dapat dikatakan “kurang layak”. Analisa tingkat kepuasan pengguna terhadap kinerja parkir pada saat waktu sibuk dapat dikategorikan “cukup layak”.
