Abstract

The purpose of this study was to analyze the lead (Pb) levels in fish for consumption on the East Pentadu Coast, Gorontalo Province, and to evaluate whether these levels were within the maximum limits according to the applicable quality standards. This study was conducted at three locations: the boat dock, the mangrove area, and the auction site. The method used in this study was a quantitative descriptive method using a purposive sampling technique. The population in this study included fish for consumption on the East Pentadu Coast, the muscles of which were collected at all three locations. The results showed that the highest lead levels in Cetoscarus ocellatus fish were 0.0003 mg/kg, far below the maximum limit of SNI 7387:2009, which is 0.1 mg/kg. Therefore, consumption of fish from the East Pentadu Coast is still considered safe, although the cumulative Pb properties still require vigilance.

Abstract

Adolescents are individuals undergoing significant development. The nutritional intake required by adolescents varies to achieve balanced nutrition, but if not met, it can lead to various health problems, such as anemia. Anemia is one of the health issues commonly experienced by adolescent girls, especially during puberty. Lack of knowledge and awareness about anemia prevention is a primary factor influencing adolescents' behavior in maintaining their health status. The utilization of engaging and interactive educational media, such as animated videos and digital literacy-based media (Canva), can be an effective strategy in improving anemia prevention behavior among adolescents. This study aims to determine the effect of anemia prevention education through a combination of animated video media and digital-based literacy media (Canva) on the behavior of adolescent girls at SMAN 1 Marisa. This study employed a quasi-experimental design with a pretest-posttest approach without a control group. The sample consisted of 196 adolescent girls from grades X and XI, selected using proportional random sampling technique. The instrument used was an anemia prevention behavior questionnaire that had been tested for validity and reliability. Data were analyzed using the Wilcoxon Signed Rank Test. The results showed a significant increase in anemia prevention behavior in the aspects of knowledge (p = 0.000), attitude (p = 0.000), and action (p = 0.000) after the educational intervention. The conclusion of this study states that anemia prevention education using a combination of animated videos and digital-based literacy media (Canva) has an impact on the behavior of adolescent girls at SMAN 1 Marisa, in terms of knowledge, attitudes, and actions. The use of engaging and easily accessible educational media can be an alternative in health promotion among adolescents.

Abstract

Solang M, Lamondo D, Kumaji SS. 2017. Zinc, calcium, protein, lead, mercury, and the sensorics quality of cireng snacks supplemented with blood cockle (Anadara granosa). 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.

Abstract

Teo tuber flour (Tacca leontopetaloides) is a local carbohydrate source with potential to be developed as a functional food. However, information about its starch composition and glycemic load is still limited, even though these two parameters are important in determining blood glucose response after consumption as well as the carbohydrate quality of a food. This study aims to determine the amylose and amylopectin content of teo tuber flour and evaluate its glycemic load using male white rats (Rattus norvegicus). The study used a descriptive method with a quantitative approach and a laboratory experimental design. Analysis of amylose and amylopectin content was done using spectrophotometry with the DNS method and an amylose standard curve. Glycemic load was determined by measuring the rats’ blood glucose response after giving them teo tuber flour porridge and pure glucose, then calculated using the Incremental Area Under the Curve (iAUC) method. Research results show that teo yam flour contains 15.727% amylose and 64.389% amylopectin, meaning its starch composition is dominated by amylopectin. Rats fed with teo yam flour porridge showed lower and more stable blood glucose responses compared to rats given pure glucose. The glycemic load value of teo yam flour is 17, which falls into the medium category. These findings suggest that teo yam flour has the potential to be developed as a functional food that can help maintain stable blood glucose levels. Further research is needed to explore starch modification techniques that can reduce glycemic response and enhance its health benefits.

Abstract

Anemia is a condition when the hemoglobin (Hb) level in the blood is lower than the normal limit. Adolescent girls are at high risk of experiencing anemia due to regular blood loss during menstruation, and iron (Fe) deficiency is the main factor causing iron deficiency anemia, which is a condition resulting from insufficient iron for hemoglobin synthesis in erythrocytes that function to transport oxygen. The aim of this study is to determine the serum iron (Fe) levels and the number of erythrocytes in anemic adolescent girls who receive a free nutritious meal program. The research method used is an analytical observational approach with a cross-sectional design. The population in this study consisted of 80 anemic femal students, with a sample size of 40 anemic female students. The research results show that the iron levels in anemic adolescent girls who received the MBG program averaged 97.14 ± 91.67, and the average erythrocyte count was 4.87 ± 0.54. The results indicate that the average of both variables is still within the normal range. Meanwhile, the results in the group that has not received free nutrition show an average erythrocyte count of 4.73 ± 0.31, while the average iron level is at 47.50 ± 19.39.

Abstract

Salt lick merupakan sumber daya habitat yang dapat dimanfaatkan oleh mamalia untuk memperoleh mineral serta melakukan berbagai aktivitas seperti mencari makan, bergerak, dan berinteraksi. Informasi mengenai kunjungan dan perilaku mamalia pada salt lick di Suaka Margasatwa Nantu–Boliyohuto masih terbatas, terutama setelah munculnya African Swine Fever (ASF) pada bentang alam di sekitarnya. Penelitian ini bertujuan mengidentifikasi taksa mamalia yang mengunjungi satu lokasi salt lick serta mendeskripsikan pola perilakunya selama periode pengamatan. Penelitian dilaksanakan pada 23 Februari–23 Maret 2026 menggunakan dua kamera jebak yang beroperasi selama 24 jam dan didukung pengamatan lapangan. Perilaku yang terekam diklasifikasikan berdasarkan ethogram untuk menggambarkan aktivitas mamalia selama berada di lokasi penelitian. Sebanyak lima taksa mamalia terdeteksi, yaitu Macaca hecki, Bubalus depressicornis, Viverra tangalunga, Muridae, dan Sciuridae. Macaca hecki merupakan taksa yang paling sering terdeteksi dan menunjukkan beragam aktivitas, termasuk mencari makan, berjalan, berpindah, kewaspadaan, serta interaksi sosial. Bubalus depressicornis terutama terdeteksi pada malam hari dengan aktivitas berjalan, eksplorasi, kewaspadaan, dan kunjungan ke area salt lick. Viverra tangalunga hanya terdeteksi dalam jumlah terbatas pada periode malam hari, sedangkan Muridae dan Sciuridae menunjukkan deteksi yang relatif sedikit. Kelompok Suidae tidak terdeteksi selama periode penelitian. Hasil ini memberikan gambaran awal mengenai kunjungan dan perilaku mamalia pada satu salt lick di Suaka Margasatwa Nantu–Boliyohuto dan dapat menjadi data dasar untuk pemantauan jangka panjang, termasuk untuk mengevaluasi perubahan aktivitas mamalia dan kemungkinan perubahan keberadaan Suidae di kawasan tersebut.

Abstract

The maleo bird (Macrocephalon maleo) is a species endemic to Sulawesi that is threatened with extinction due to habitat destruction and natural predation pressure. The Hungayono area within Bogani Nani Wartabone National Park serves as a crucial nesting habitat for the maleo, yet current population data remain limited. This study aimed to monitor the maleo population and analyze the factors influencing it in the Hungayono area. Research was conducted over  days between August and September , employing both direct (visual) and indirect (vocalizations and tracks) observation methods using the concentration count technique across two habitat types: nesting grounds and roosting sites. Data were analyzed using descriptive quantitative methods to calculate population density and estimate the total number of individuals. The study identified 84 pairs of maleo birds ( individuals) engaged in nesting activities, with a peak population density of  individuals/ha. Observed natural predators included monitor lizards (Varanus salvator) and spotted doves (Spilopelia chinensis), with frequencies of  and individuals, respectively. Key factors influencing the population included the availability of nesting habitat, predation pressure, climatic disturbances, and vegetation conditions. Even though the threat posed by predators is quite significant. The study concludes that the Hungayono area remains a vital reproductive habitat; however, predator management and continuous monitoring are essential to ensure the long-term survival of the maleo population.
