Abstract

Tujuan dari penelitian ini adalah untuk mengetahui penurunan mutu keripik pisang kepok rasa coklat kemasan aluminium foil selama penyimpanan pada suhu yang berbeda, dan untuk menentukan masa kadaluarsa keripik pisang kepok rasa coklat kemasan aluminium foil menggunakan metode ASLT melalui pendekatan Arrhenius. Berdasarkan hasil penelitian  kadar air dari minggu ke-1 sampai minggu ke-5 cenderung tidak stabil, hal ini disebabkan karena kelembaban, suhu, maupun kondisi lingkungan yang berubah-ubah. Kadar Free Fatty Acid (FFA) yang semakin tinggi setiap minggunya karena dipengaruhi oleh kondisi lingkungan seperti suhu sehingga mempengaruhi kenaikan kadar asam lemak bebas pada produk keripik pisang rasa coklat. Sedangkan uji organoleptik pada minggu terakhir selama penelitian tingkat kesukaan terhadap warna dan aroma pada produk keripik pisang rasa coklat dengan nilai agak suka, tingkat kesukaan terhadap rasa dan tekstur dengan nilai netral. Parameter titik mutu kritis yang tepat untuk penentuan perhitungan masa kadaluarsa yaitu kadar FFA menggunakan metode ASLT melalui pendekatan Arrhenius. Umur simpan produk keripik pisang rasa coklat pada setiap suhu perlakuan dengan penyimpanan selama 5 minggu dengan hasil lama umur simpan: suhu ruang = 122,62 hari atau 4,09 bulan, pada suhu 40 °C = 122,58 hari atau 4,06 bulan, dan pada suhu 50 °C = 121,55 hari atau 4,05 bulan.
Study of Bioactive Content Liberica Coffe Powder (Coffea liberica. Var) and Bajakah Tampala Roots (Spatholobus littoralis) Growing in Peatland Using GC- MS Saputera, Saputera; Setyowati, Erni Dwi Puji; Mahendra, Wayan Riki; Zulkifly, Rahmad

Abstract

Liberica coffee (Coffee liberica Var.)  is known as a typical peatland coffee because of its ability to adapt to peat soils compared to other types of coffee. The bajakah tampala plant (Spatholobus littoralis Hassk) is a plant from the genus Spatholobus. The roots of the bajakah tampala are used empirically as medicine by the Dayak community. Based on hereditary experience, boiled water from bajakah tampala root can be used as a medicine for stomach pain, diarrhea, and dysentery. This plant contains phenolics, flavonoids, tannins and saponins so bajakah tampala can be used as herbal medicine. Until now, the active compound content of the combination of Liberica coffee and bajakah tampala root is unknown. Thus, this research aims to determine the bioactive content of Liberica coffee and bajakah tampala roots. This research was conducted using two factorials, Randomized Complete Block Design (RCBD), where Factor 1, consists of Liberica coffee powder concentrations, and Factor 2 consists of bajakah tampala powder concentrations. Each factor had 3 levels.  Bajakah tampala roots were sorted, washed, cut into small pieces, oven-dried at 50°C for 6 hours, ground, sieved using an 80 mesh, then weighed and ready to be used as an herbal coffee additive. Bajakah tampala was oven-dried at 50°C for 6 hours, ground, sifted, then mixed with Liberica coffee powder according to treatment groups (L1, L2, L3 and B1, B2, B3) for 9 combination treatments with 3 repetitions. Analysis of bioactive compounds in this research was determined using GC-MS. The analysis results show that 8 main components seen based on retention time, namely caffeine, hexadecanoic acid, palmitic acid, hexadecanoic acid, ethyl ester, octadec-9-enoic acid, octadecanoic acid, stearic acid, octadeca-9,12-dienoic acid methyl, 9,12-octadecadienoic acid (Z, Z)-Lino and ethyl linoleate. It is recommended that further research be carried out regarding the bioactive content of Liberica and bajakah coffee as herbal medicine.

Abstract

The rasau plant grows in riparian forest areas within tropical peat swamp forests. It is a lignocellulosic material with potential as a raw material for particleboard. Before being used as a raw material, a feasibility study must be conducted on the rasau plant (Pandanus helicopus). The stems of rasau were analyzed for cell dimensions, cell proportions, chemical composition, and physical and mechanical properties. The results indicate that the fiber dimensions and proportions, as well as the physical and mechanical properties, demonstrate that rasau stems are suitable for use as a raw material for non-structural particleboard. Rasau can be utilized as a raw material for particleboard, provided the particles undergo cold water soaking and use phenol-formaldehyde or melamine-formaldehyde resin adhesives, followed by hot pressing
