Oil palm smallholders have rapidly grown but their performance is relatively low compared to other producer groups. One of the programs that are expected to address this is certification. However, only a small percentage of smallholders received the certification in practice. This study was conducted to analyze the effectiveness of certification to improve smallholder oil palm plantations’ performance. The study was conducted in North Sumatra, South Sumatra, and Riau. Data were collected from 707 sample smallholders. Performance is measured from economic aspects, namely productivity, selling prices, fertilizer usage and harvest criteria, and environmental aspects, namely waste treatment and paraquat pesticide usage. The data were then analyzed using the One-Way ANOVA test and the One-Sample t-test. The results show significant differences in productivity and selling prices between the plasma and other smallholder groups, but not between the certified and non-certified ones. The results also show significant differences in the waste treatment between the certified and non-certified groups, but not in paraquat pesticides. Therefore, it can be concluded that certification cannot improve smallholder oil palm plantations’ performance if not followed by intensive and sustainable partnership assistance.

<p>Excessive usage of synthetic pediculicides, such as permethrin, lindane, and malathion, can induce resistance, environmental pollution, health problems, and even death. Efforts to prevent the side-effects of synthetic pediculicides are needed, one of which is by shifting to powerful yet safe natural pediculicides, such as Citrus limon (lemon) and Allium sativum (garlic). This study aimed to observe the effective concentration of Citrus limon and Allium sativum in vitro on the mortality of Pediculus humanus capitis (P. h. capitis). This research was an experimental laboratory study conducted in July to September 2019 in the Laboratory of Parasitology at Faculty of Medicine, University of Riau, while the making of Allium sativum extract was done at the Faculty of Mathematics and Science, University of Riau. A total of 288 samples of adult P. h. capitis was taken from children in two orphanages in Pekanbaru. Citrus limon juice and Allium sativum extract of 25%, 50%, 75%, and 100% concentrations, permethrin 1% as the positive control, and distilled water as the negative control were used in this study, and repetition was done three times. P. h. capitis mortality was observed every 10 - 120 minutes, characterized by the absence of movement of the legs and antenna. Data analysis was performed after 120 minutes with the one-way ANOVA test, LSD (=0.05), and Lethal Concentration 50 test (LC50). The one-way ANOVA test results of this study showed that statistically Citrus limon juice and Allium sativum extracts showed differences in each treatment formulation of juice on P. h. capitis mortality (Sig 0.017&lt;0.05 and Sig 0.000&lt;0.05) and LC50 juice of Citrus limon and Allium sativum extract by 51.999% and 72.426%.

Nusantara Bioscience 9: 385-391. Blood cockle (Anadara granosa) is a potential nutritious food with high economic value. This study aims at evaluating the level of zinc, calcium, protein, mercury, lead, and the sensorics quality of cireng (traditional Indonesian snack made from fried-tapioca flour dipped into sauces) supplemented with blood cockle. This study used complete randomised design, where the treatment factors consisted of flour made from blood cockles to supplement the flour used in making the cireng snacks. The concentration of the treatment factors were 0%, 5%, 10%, 15%, and 20%. The data were analyzed using the One Way ANOVA test and LSD test. This study shows that blood cockles’ supplementation significantly increases the level of protein (p=0.05), zinc (p=0.031), calcium (p= 0.016), lead (0.000), mercury (p= 0.022) of the cireng snacks. Supplementation of blood cockles has increased the preference toward cireng’s flavor, aroma, and color by 10%, whereas the level of preference toward the texture of cireng which used the blood cockle has increased by 20% compared to cireng product with non-supplemented flour. The level of lead (Pb), and Mercury (Hg) are below the Indonesian National Standard (SNI). Supplementation of blood cockles from Gorontalo in the flour used in making the cireng snacks produced snacks with a better nutrition value and safe to consume. Also, the flavor, color, texture, and aroma are acceptable.
