“…Meanwhile, the LOF values of RE and CA are insignificant (p>0.05), indicating that the model is acceptable for predicting optimization conditions. A nonsignificant LOF value (p>0.05) suggests that the response data are compatible with the model (Rai Widarta et al, 2022).…”

This study presented the impact of pH and octenyl succinic anhydride (OSA) concentration on the esterification reaction of heat-moisture-treated sago starch (HMT-S) using response surface methodology to achieve optimum degree of substitution (DS), reaction efficiency (RE), and water contact angle (CA). The results showed that HMT-OSA sago starch (HMT-OS) starch exhibited an optimum pH of 7.26 and an OSA concentration of 4.53%. The DS value, RE, and water CA of optimized HMT-OS starch were 0.0121, 33.07%, and 90.11°, respectively. Furthermore, the optimized HMT-OS was used to evaluate the effect of starch modification on film characteristics. HMT-OS film has the best moisture-proof and mechanical properties compared to control (NS), HMT-S, and N-OS films, as indicated by lower water vapor permeability (28.69 g H2O.mm/s.m2.Pa × 10-11), water solubility (26.61%), higher CA (104.40°), elongation at break (85.63%), and transparency (3.25% mm-1). According to the scanning electron micrographic images, the absence of cracks or pores was attributed to the waterproof properties and flexibility of the film. Conversely, x-ray diffraction results showed that the crystallinity of HMT-OS film decreased to 36.05%.

Porang (Amorphophallus muelleri Blume) is one type of tuber plant that is starting to be widely produced in Indonesia because it has high economic value. This is because porang is widely used in the food, health, cosmetic, and manufacturing industries. Over the last decade, the export volume has increased drastically. In 2020, the export value of Indonesian porang was dominated by Thailand with a market share of 59.3%, followed by China with a total of 130 shipments, or 47.84% of total porang exports. Export share to Thailand and Australia increased significantly in 2020, with an increase of 920.1% and 526.7%, respectively. The purpose of the study was to determine the internal and external factors that affect the development of porang and obtain strategies for porang development at PT Al-Fatih Porang Indonesia. Qualitative descriptive research with Porter's Diamond Theory to determine the competitive position of porang agribusiness and SWOT analysis to determine the internal and external factors of porang agribusiness at PT Al-Fatih Porang Indonesia The results of Porter's Diamond Theory analysis showed that in PT Al-fatih Porang Indonesia's conduct of porang agribusiness development, each subsystem has not been mutually supportive and related to each other. This can be seen in the marketing and agribusiness subsystem, which is still difficult. The appropriate strategy for the development of porang at PT. Al-Fatih Porang Indonesia is to optimise the utilisation of porang.

Porang (Amorphophallus oncophyllus) thrive under shaded conditions and has been planted under plantations. As oil palm plantations area in Aceh is growing; the effect of shading under oil palm plantation has not been previously reported. The material used is bulbil from the porang plant. Meanwhile, the oil palm stands used were 8-10 years old with the canopy covering >80% of the land. The experimental design used is a Completely Randomized Block Design with the treatment of spacing settings of 40 x 40 cm; 75 x 75 cm; 80 x 80 cm; 90 x 90 cm and 100 x 100 cm. Experiments were conducted in four replicates. Data were analysed using One Way Anova, followed by posthoc Tukey HSD test. Results shows that the spacing had a significant effect on its growth, especially the age of shoot emergence, plant height, stem diameter and number of leaves. The age of budding which allows early shoots to appear is at a spacing of 40 x 40 cm, as well as the plant height parameters at observations 4, 5, 6 and 7 WAP. Meanwhile, at the age of 8 and 9 WAP, the best plant height growth was at 80 x 80 cm spacing.
