Abstract

Sargassum belongs to Phaeophyceae is widely distributed in Indonesian waters, including Kabung Island. Seaweed has bioactive compounds that potential to be developed. In the health sector, one of the global problems that still increasing is the bacterial infection. This condition leads us to explore antibiotic from natural resources to overcome this problem. Sargassum grow abundantly in the waters of Kabung Island and this genus has not been utilized by local community. For this reason, the aim of this study is to evaluate the antibacterial and cytotoxic activity from ethyl acetate extract of Sargassum from Kabung Island, West Kalimantan. Antibacterial activity test of the ethyl acetate extract against E. coli and S. aureus was conducted using the diffusion method with concentration series of 100; 50; 25; 5; 1; and 0.1 g/mL. While, the assessment of cytotoxic activity was carried out with concentration of 10; 100 and 1000 g/mL. The result showed that ethyl acetate extract of Sargassum from Kabung Island only showed antibacterial activity against E. coli bacteria. The greatest inhibition zone was 11.59 mm at a concentration of 100 g/mL, while in the cytotoxic test exhibited that the LC50 was more than 1000 ppm, so it was considered into non-toxic category.

Abstract

Watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai.) is one of the horticultural commodities that have a fairly high economic value. Watermelon plants are more dominant in producing male flowers than female flowers. Therefore it is necessary to be able to change the sexual expression of watermelon flowers. One of the efforts that can be made to increase production watermelon is by administering the growth regulating agent ethepon. This study aims to find the best concentration of ethepon on watermelon growth and yield. This study used a randomized block design (RBD) consisting of 5 treatments and repeated 4 times. The treatment given was giving the concentration of ethepon which consisted of 5 levels, namely control (0 ppm), 100 ppm, 200 ppm, 300 ppm and 400 ppm. The parameters observed were plant length, number of leaves, when the first male flower appeared, when the first female flower appeared, the number of male flowers, the number of female flowers, the number of fruit planted, the weight of fruit planted and the length of the fruit. The results of research that have been carried out show that the application of ethepon with a concentration of 100 ppm is the best concentration in increasing when the first male flowers appear, the number of male flowers, the number of female flowers, the number of fruits per plant and the weight of fruit per plant.

Abstract

Currently, need for wood as a raw material for making boards has increased, which has reduced the availability of forest resources. To overcome this problem, industrial waste or other lignocellulosic materials are used to make particle board with the aim of efficient use of wood. Particle board has advantages, namely the use of raw materials can be either wood or non-wood waste. Therefore, particle board processing can overcome the problem of handling wood waste which has not been optimally carried out. This research aimed to analyze the physical properties of particle board made from bamboo and sugar palm waste. This study used an experimental method with a completely randomized design (CRD) with one factor (adhesive content), namely 10%, 12%, and 14%. The results of this study showed that physical properties of bamboo particle board at adhesive content of 10%, 12%, and 14% ranged from, respectively: water content (10.26%, 9.96%, dan 9.79%); density (0.69 gr/cm3, 0.68 gr/cm3, dan 0.71 gr/cm3); thickness swelling (21.57%, 20.07%, dan 19.23%). While the palm sugar particle board with adhesive content of 10%, 12%, and 14% respectively: water content (11.29%, 10.91%, dan 10.22%); density (0.70 gr/cm3, 0.69 gr/cm3, dan 0.71 gr/cm3); thickness swelling (26.00%, 22.90%, dan 22.85%). From the physical properties of the two types of particle board, the water content and density of particle board fulfilled JIS A-2003 standard, while thickness swelling did not fulfilled JIS A-2003 standard. Based on the value of moisture content and density, the use of bamboo particle board and palm sugar is suitable for interior materials.

Abstract

Desa Bakau is located in Sambas Regency, West Kalimantan which has the potential for mangrove forests with an area of ± 305 Ha. Ecologically, mangrove forests have various roles, one of them is as a habitat for various types of aquatic biota, including gastropods. Several gastropods have important economic value for the community as food and medicine. The local community catches and consumes the mangrove gastropods. As a food ingredient, gastropods have a high nutritional content and essential macro minerals. Gastropods can be used as an alternative source of animal protein at an affordable price. This study aimed to determine the nutritional value of the gastropod Cassidula from the mangrove area of Desa Bakau, Sambas Regency, West Kalimantan. Quantitatively, nutrient content such as protein, carbohydrates, fat, moisture, and ash content were determined according to the AOAC (2005) standard method, whereas macro minerals content (Na, K, Mg, Ca, and P) was carried out according to the AOAC method (2016) using Atomic Absorption Spectroscopy (AAS). The result showed that Cassidula had a protein content (57.02%) with the highest value compared to other types of nutrients. In addition, Cassidula also contained an essential macro mineral, such as calcium (37.0006 mg/kg) with the highest value followed by sodium (21.7364 mg/kg), respectively. The results showed that Cassidula can be used as an alternative food ingredient for human.

Abstract

The Coconut coir contains active compounds that can inhibit bacterial activity, namely tannins. Guava leaves can inhibit microbial growth because they contain flavonoids, triterpenoids, saponins, tannins, and eugenol. The purpose of this study was to find out the use of coconut coir for the natural preservation of palm sap, to find out the use of guava leaves, and to find out the combination of using coconut coir and guava leaves for the natural preservation of palm sap. This research was carried out in June-July 2022 in Prestasi District, Langkat Regency, North Sumatra Province. This study used a randomized block design (RBD) method, with two factors, namely the addition of coconut fiber (K) and guava leaves (J), each consisting of 3 treatments, namely: K0 = 0gr; K1 = 80gr; K2 = 120gr; J0 = 0gr; J1 = 5gr; J2 = 10gr with 3 repetitions. The results showed that the use of 5 grams of coconut coir in preserving palm sap was beneficial in maintaining a pH value above 6 and lower sugar content of 13.6 °Brix. The use of guava leaves of as much as 120 grams is useful in reducing the water content in palm sap up to 84.00%. The use of a combination of coconut coir and guava leaves is beneficial in reducing the water content in palm sap, which is 82.00%.

Abstract

The existence of seagrass in coastal areas can affect marine biota that live around it. Seagrass has an important role as an area of ​​care, spawning, and protection. This study aims to determine the success of conserving seagrass beds of the Enhalus acorodies species in terms of bivalve diversity on the south coast of East Lombok. The research was conducted using transect and observation methods. The data obtained were analyzed using evenness index, diversity index, and species richness. The results of the study found 10 types of Bivalves in Poton Bako. Bivalves diversity index is included in the medium category of 2,228. The evenness index of bivalves was 0.409 in the low category. Then, the species richness index is 1.653 in the low category. The species diversity of Bivalvia in seagrass beds in Poton Bako is still relatively moderate so that the sustainability of the seagrass species Enhalus acoroides can be said to be maintained. The existence of a feed source or substrate derived from the remains of seagrass is used as a source of feed. The conservation of Enhalus acoroides seagrass needs to be maintained so that it has an impact on the survival and diversity of Bivalves in the area.
