Swim bladder is a marine byproduct and a potential source of collagen needed by food, cosmetical, biomedical and pharmaceutical industry. This study evaluated the effectiveness of alkaline pretreatment and papain enzyme on the characteristics of collagen from the catfish swim bladders. TThree concentrations of alkaline (0.05; 0.1 and 0.15 M) with were used to pretreat the swim bladders for 2; 4; 6; 8; 10 and 12 hours. The collagen was also treated by papain enzyme with concentrations of 0; 5,000; 10,000; 15,000 and 20,000 U/mg for 24 and 48 hours. The result showed that pretreatment using NaOH 0.05 M for 6 hours effectively reduced the noncollagen protein (p<0.05). Meanwhile, the treatment using papain enzyme with concentration of 5.000 U/mg for 48 hours improved the collagen solubility. The FTIR of collagen showed the existence of a triple helix structure. Meanwhile, the thermal analysis showed collagen gelation transition temperature (Tg) was at 88oC.

The study aimed to analyze the effect of frozen minced fish storage and washing cycle to the quality of surimi and kamaboko catfish (Pangasius sp). The experimental design used was randomized compact design with treatment of storage time (0,14,28) day and washing cycle treatment (1,2,3, and 4). The results showed that the storage time and washing frequency significantly affect the expressible water, while not significant effect on white duct, folding test and teeth cutting test. The highest values of surimi and kamaboko catfish from each treatment are whiteness test at surimi of 49,27% and 63.55% at kamaboko, folding test with value 7, teeth cutting test 7 and expressible water have the highest value of 35 at kamaboko and has a TVBN value which is still below the decay threshold, which is in the range of 11.295-12.085 mg N/100 g.

Mangrove forests are a unique ecosystem and are important in providing life support for coastal communities. The community group (Kelompok Kariangau Lestari) is a community in Kariangau RT 02 Village that has yet to receive intensive training or socialization regarding the diversification of mangrove derivative products. Mangrove plants are not used properly, so they are only left to grow wild around residential areas. The settlement around the mangrove is used as a tourist attraction, namely Jembatan Panjang Mangrove Kariangau. Still, this tourist attraction is not optimal because the long bridge is the only attraction, and the bridge has been damaged, so there is no longer a source of income for residents. Therefore, this community service activity aims to train community groups to utilize mangrove fruit as a processed food product to attract tourism to the Jembatan Panjang Mangrove Kariangau and increase residents' income. This activity began with observing the condition of the mangrove forest and holding discussions with the local community regarding efforts to increase mangrove forest productivity. In this activity, minimizing processing tools was also carried out to make processed food products and determine the right formulation for processed food products. The evaluation was carried out in two discussions, namely product evaluation, with the result that residents could accept the product as consumers, and activity evaluation, with the result that residents felt this activity was very useful for increasing the current use of mangrove plants.

ABSTRAK Tujuan penelitian ini untuk mengetahui pengaruh konsentrasi pelarut etanol pada ekstraksi antioksidan dari kulit nanas. Kulit nanas didapatkan dari wilayah Balikpapan Utara. Kulit nanas dikeringkan pada suhu 60°C dan berat sampel berkurang 78,70%. Sampel kering dihaluskan hingga berukuran 100 mesh. Ekstraksi dilakukan dengan metode Soxhlet selama 4 jam dengan menggunakan variasi pelarut etanol dengan konsentrasi 25%, 40%, 55%, 70% dan 85%. Larutan hasil ekstraksi dievaporasi 50 – 60°C hingga membentuk ekstraks kental etanol yang berwarna kuning kecokelatan dengan bau khas nanas. Hasil perhitungan rendeman menunjukkan bahwa tidak ada perbedaan signifikan ekstraksi dengan pelarut etanol dengan konsentrasi 25 – 70%, yaitu kurang 10%. Rendeman tertinggi diperoleh dari ekstraksi dengan 85% pelarut etanol, yaitu sekitar 20%. Analisis fitokimia dilakukan dengan uji kualitatif beberapa senyawa antioksidan, yaitu flavonoid, alkaloid, polifenol, terpenoid dan steroid. Ekstrak etanol kulit nanas mengandung flavonoid dan polifenol pada setiap variasi konsentrasi pelarut etanol, namun negatif terhadap alkaloid dan steroid. Hanya ekstrak etanol dari 55 – 85% pelarut etanol yang memberikan hasil positif pada terpenoid. Ekstrak etanol dari 85% etanol memiliki intensitas perubahan warna yang paling tinggi. Sehingga, ekstraksi kulit nanas menggunakan metode sokletasi memberikan hasil yang optimal dengan menggunakan pelarut 85% etanol.

Fish bone can be utilized as an additional ingredient in food processing. Cookies are one of the processed dry cakes that utilize the nutritional content found in the by-products of milkfish bones, thus becoming an alternative snack for osteoporosis patients. The common process of milkfish bone processing is grinding, which can be added to Cookies products. Cookies are sweet dry cakes made from wheat flour. Cookies, as dry food products, have a relatively long shelf life, thus maintaining product durability (approximately up to one year) and are easy to carry due to their small volume and weight resulting from the drying process. The aim of this research is to determine the effect of milkfish bone processing on the flour content and Cookies on proximate content, protein content, moisture content, ash content, and calcium and phosphorus content in milkfish bone flour cookies. The research method was conducted using an experimental method with two treatments, namely chocochip cookies and savory cookies, which were analyzed using one-way Anova in the XLStat software. The results showed that fortified milkfish bone chocochip cookies had nutritional content such as moisture content (0.72%); ash (4.18%); protein (7.26%); fat (27.33%); carbohydrates (60.51%); calcium (0.14%); phosphorus (0.12%), and the nutritional content of savory cookies fortified with milkfish bone had nutritional content such as moisture content (7.83%); ash (1.83%); protein (4.33%); fat (28.46%); carbohydrates (57.70%); calcium (0.18%); phosphorus (0.17%).

East Kalimantan Province has great opportunities as a buffer for the IKN economy based on the utilization of marine potential. Eucheuma cottonii and Gracilaria sp. are the red seaweeds (Rhodophyta) most widely cultivated in Indonesia. This study aims to analyze the proximate content in two types of red seaweed, namely E. cottonii (offshore cultivation) and Gracilaria sp. (pond cultivation) obtained from farmers in dry conditions cultivated around the waters of Balikpapan, East Kalimantan, Indonesia. The results of the analysis showed significant differences between cultivation locations. Gracilaria sp. (pond cultivation) taken from Handil (HTK) and Babulu Laut (BALUKE) is considered potential because it has low water content (HTK 26.99 ± 0.02%), and has higher ash content (BALUKE 31.18 ± 0.41%), fat (BALUKE 0.36 ± 0.01%), protein (BALUKE 10.01 ± 0.01%), and crude fiber (HTK 1.90 ± 0.16%) compared to E. cottonii. These findings provide important information for the development of seaweed as a natural resource for the food and health industries.

Agricultural fertilizers generally use chemical ingredients. Chemical fertilizers are relatively expensive, and their subsidized versions are becoming scarce. Therefore, the application of organic fertilizers can be an alternative to replace chemical fertilizers. The community of RT. 36 in Karang Joang Village is located in the Sungai Wein Protected Forest (HLSW) area, where there are many fallen leaves along the roads and in residents' yards. The residents in this area have expressed concerns about the cost of fertilizers for their agricultural needs. The aim of this activity is to help address this issue by providing a shredder to produce organic fertilizers. The activity began with a site survey, followed by community empowerment activities, which included the design and construction of a leaf shredder, socialization of tool usage and fertilizer production to the community, collection of fertilizer raw materials, and the production of organic fertilizer. The outcome of this community service activity is an increased understanding among the community of how to utilize dry leaves and the production of organic fertilizers that have been made and packaged for easy transportation and use. The conclusion drawn from this activity is that the goal of utilizing the leaf shredder to produce organic fertilizers has been achieved, thereby fulfilling the household agricultural needs in the surrounding area.
