OPTIMALISASI KEBERADAAN EKOSISTEM MANGGROVE UNTUK MENCEGAH ABRASI PANTAI DI PULAU TIDUNG. http://jurnal.borneo.ac.id/index.php/borneo_saintek/article/view/4196 The existence of mangroves is an ecosystem unit located in coastal areas. Coastal areas that have a lot of existence of mangrove ecosystems, of course these coastal areas will be well maintained and minimize the impact of damage that arises, as well as many marine life that is guaranteed. Mangroves have benefits as a place to live, find food, and breed marine biota. The classification of mangrove trees on Tidung Island can be differentiated based on the presence of elements present in the mangroves, namely the shape of the leaves, the shape of the stems, and the mangrove roots that stick into the coastal surface. Generally, the mangroves on Tidung Island are still around the coast. Efforts to optimize distribution in planting mangrove ecosystems are of course still being attempted in handling the preservation of coastal ecosystems around Tidung Island, both from the government and the surrounding community. The height of the mangroves on Tidung Island can be measured by how long the mangroves have been planted. The taller the mangrove trees, the greater the benefits provided to communities around the coast. In addition, mangroves can also function to prevent abrasion as well as marine biota as a place for carbon absorption (blue carbon) because basically mangroves are an important element in efforts to blue carbon in coastal areas which are useful for the continuation of human life.

Difficulties for students who do not have or master the use of the latest telecommunications equipment, and live in areas that are not covered by telecommunications networks. Of course there must be an appropriate alternative technology that can be used. Where one of them uses broadcast technology through "community radio". Community radio is a radio broadcasting station that is owned, managed, earmarked, initiated, and established by a community. Community radio to disseminate or broadcast information in the form of sound (audio) such as talk, news, or music, through radio waves at a certain frequency. Community radio is useful for distance learning activities, both in situations where there is a pandemic that limits face-to-face activities, or situations without a pandemic, such as overcoming technological limitations in areas that are not covered by cable or cellular telecommunications networks for internet applications.

UNTUK FILTER AIR TANAH DI KOTA TARAKAN http://jurnal.borneo.ac.id/index.php/borneo_saintek/article/view/4199 The city of Tarakan has the potential of ground water for clean water needs. But for its use, it nedds to be treated first so that theÂ quality is in accordance with the required quality standards. Crab shell (Scylla sp.) waste is used as a filtration technology for water treatment. The purpose of this research was to study the effetiveness of using crab shells as a ground water filter in Tarakan City. The research method used in this study was an experimental method with a complete random design (RAL). Repetition was done three times. The material used was crab shell with a filter level of 30, 60 and 100 cm. Crab shells were combined with the use of activated charcoal, quartz sand and gravel to determine the best composition. The parameters that were tested according to the Regulation of the Minister of Health No. 32 of 2017 (Water Quality Standards for Sanitary Hygiene Needs) are turbidity, color, odor, pH, Temperature, TSS, TDS, nitrate, nitrite, iron (Fe) and manganese (Mn). The studyâ€™s findings demonstrated that the crab shellâ€™s filtering effectiveness is quite low. For the pH parameter, the effectiveness value increased succcessively based on the filterÂ level of 30,60 and 100 cm which was 54, 71, 80% and the Mn paraneter successively was 74, 92 and 81%. While the parameters of turbidity, color, TDS, TSS, nitrite, nitrate, and iron actually decreased the value of water quality, when compared to the value of standard water.

The purpose of this study was to determine the effect of the addition of coffee grounds on consumer acceptance and the nutritional value of tilapia cendol products. This study used a completely randomized design (CRD), with 4 treatments adding coffee powder 0 g, 4 g, 6 g, and 8 g. The results showed that the addition of coffee grounds had an effect on the hedonic results of tilapia cendol. The best cendol according to consumer acceptance based on hedonic code K2 results with the addition of 6 g coffee powder with a moisture content of 65.34%, ash content of 0.48%, fat content of 0.52%, protein content of 11.13%, and carbohydrate content of 23 .53%.

The cultivation of seaweed (Kappaphycus alvarezii) in the Coastal Waters of Amal Baru, Tarakan City, is traditionally done using the longline method. The gillnet method is the most used method by seaweed farmers because it is flexible in choosing locations and relatively inexpensive. The research aims to determine the difference in the number of seaweed seedlings on the absolute and specific growth rates. This study used a Completely Randomized Design (CRD) with 4 treatments and 3 replications. Treatment P1 (1 bundle), P2 (2 bundles), P3 (3 bundles), and P4 (4 bundles). The results showed that the growth of seaweed seedlings with different numbers of bundles influenced absolute and specific growth rates. The best treatment was found in treatment P4 with an average absolute growth rate of 80.00% and an average specific growth rate of 100%.

A river is a place of waste disposal from various land activities. The purpose of this study was to determine the condition of water quality from the physical and chemical parameters in the Sesayap River, Tana Tidung Regency. The research method used is descriptive quantitative. The results showed that the condition of river water quality in the Tideng Pale Village is temperature ranged between 25-32 oC, salinity 7-15 ppt, turbidity 1.15-4.43 mg/L, water transparency 95-125 mg/L, pH 7.2- 7.7, phosphate 0.006-0.063 mg/L, ammonia 0.038-0.449 mg/L, nitrate 0.22 to 0.28 mg/L, DO 3.10-4.52 mg/L, BOD 1.12-2.17 mg/L. River water quality in the Sesayap Village is temperature ranged between 20-30 oC, salinity 8-15 ppt, turbidity 1.99-3.75 NTU, water transparency 100-135 cm, pH 6.2-7.4, phosphate 0.025-0.038 mg/L, ammonia 0.063-0.409 mg/L, nitrates 0.23-0.26 mg/L, DO 3.25-4.57 mg/L, BOD 1.23-2.23 mg/L, whereas river water quality in Bebatu Village the temperature parameters range from 22-36 oC, salinity 10-25 ppt, turbidity 2.13-4.19 NTU, water transparency 110-130 cm, pH 6-7.8, phosphate 0.010 to 0.30 mg/L, ammonia 0.065-0.525 mg/L, nitrates 0.26-0.30 mg/L, DO 3.10-4.60 mg/L, BOD 1.17-2.23 mg/L. The conclusion of this study is that the condition of water quality is still relatively good.
