Crackers is a product made through a roasting process. This study aims to determine the effect of the addition of liquid smoke on the physical and sensory characteristics of snakehead fish crackers (Channa striata). This research method used a randomized block design (RBD) with one treatment factor and was carried out with 3 replications. The treatment used was the difference in the concentration of liquid smoke (0%, 2.5%, 5%, and 7.5%). The stages of this research include physical analysis (crispness) and sensory analysis (appearance, aroma, taste, and texture). The results showed that the treatment of different concentrations of liquid smoke had no significant effect on crispness (525.67 gf-580.67 gf). The results of sensory analysis showed that the treatment of different concentrations had a significant effect on appearance, aroma and taste, but had no significant effect on the texture of kemplang. The best treatment of this research is the A1 treatment with a liquid smoke concentration of 2.5%.
The objective of this research was to study the characteristic of edible film from carrageenan and gum Arabic with different concentration. The experiment was arranged in factorial randomized block design with carrageenan concentration and gum Arabic concentration as the treatment factors and was done in triplicates. The treatments consisted of carrageenan concentration (2%, 2,5%, and 3%) and gum Arabic concentration (0,2%, 0,4%, and 0,6%). The results showed that carrageenan concentration, gum Arabic concentration, and interaction between the two treatments significantly affected (p<5%) the thickness, tensile strength, percentage of elongation, water vapor transmission rate, and water activity. The best edible film characteristics were 0.,050 mm of thickness, 19.61 x 106 N/m2 of tensile strength, 14.095% of percentage of elongation, 7.368 g/m2.24 h of water vapor transmission rate, and 0.3028 of water activity got from interaction between 2% of carrageenan concentration and 0.2% gum Arabic concentration.ABSTRAKPenelitian ini bertujuan untuk memperlajari karakteristik edible film yang terbuat dari karagenan dan gum Arabic. Rancangan penelitian yang digunakan adalah rancangan acak kelompok dengan dua faktor perlakuan dan tiga kali ulangan. Faktor perlakuan tersebut adalah konsentrasi karagenan (2%, 2,5%, dan 3%) dan konsentrasi gum Arabic (0,2%, 0,4%, dan 0,6%). Hasil penelitian menunjukkan bahwa perlakuan konsentrasi karagenan, gum arabik, dan interaksi berpengaruh nyata (p<5%) terhadap ketebalan, kuat tusuk, kuat tarik, persen pemanjangan, laju transmisi uap air, dan aktivitas air. Karakteristik edible film terbaik yang dihasilkan dalam penelitian ini adalah ketebalan 0,050 mm, kuat tarik 19,61 x 106 N/m2, persen pemanjangan 14,095%, laju transmisi uap air 7,368 g/m2.24 h, dan aktivitas air 0,3028 pada perlakuan 2% karagenan dan 0,2% gum arabik.
A study area was at the Musi River, located in the southern part of Sumatera Island, Indonesia. This river flows in the southern area with a majorly tropical rainforest climate. For decades, it has become a substantial port used mainly for the transport of rubber, petroleum, and oil palm, which has the potential to threaten the area. Therefore, the objective of this study was to investigate the impacts of these activities by evaluating the water quality status and pollution index in the Musi River. Physicochemical parameters such as pH, salinity, temperature, dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), and total suspended solids (TSS) were measured along the river. Results of the study revealed the impact of agriculture and fish farming activities in the upstream area has affected the pH values of the water became slightly acidic. In addition, COD values at all stations were found to be high and made they could not be used for drinking water. TSS values were also found to be high at the downstream stations. According to the pollution index status, the study area was classified from low to moderate pollution.
Pulau Semambu village has potential sources of fishery products for the Indralaya area. This program aimed to socialize the manufacture of processed catfish (Clarias batracus) products. This activity is one of the efforts to fulfill nutritional needs and increase family income which is an effort to empower the creative economy through the participation of the Pulau Semambu villagers. Data and information from this service were obtained through observation and interviews. The method has used the PLA (Participatory Learning and Action) method. This service program was attended by 30 Semambu villagers. The product making was easy implemented for Semambu villagers. The post-test score in this activity were 83.36% (fish jerky) and 75.58% (fish bone cracker) regarding the understanding of the product started in definition, making, and advantages. The applicable of product making was a alternative income-generating efforts, in addition to fulfilling nutritional intake.
Permasalahan utama yang dihadapi Usaha Mikro Kecil dan Menengah (UMKM) Barokah Palembang adalah pengemasan produk olahan yang masih konvensional dan tidak ada informasi nilai gizi produk. Tujuan kegiatan ini adalah melakukan introduksi teknologi pengemasan vakum sekaligus memberikan informasi komposisi gizi produk pada kemasan. Tahapan kegiatan yang dilakukan yaitu meliputi pertama sosialisasi dan pelatihan pengemasan vakum, kedua pendampingan analisis gizi produk olahan, dan ketiga monitoring aplikasi teknologi dan penyusunan laporan kegiatan. Hasil dari kegiatan ini adalah kegiatan penyuluhan diikuti oleh 34 orang yang merupakan anggota UMKM Barokah serta melibatkan juga UMKM lainnya di Palembang. Analisis komposisi gizi produk ikan asap menunjukan bahwa ikan asap mengandung air sebanyak 7,84%, protein 17,24%, lemak 45,59%, dan abu 10,90%. Pada akhir kegiatan penyuluhan dilakukan penyerahan satu unit alat vakum kepada pengelola UMKM Barokah.
