Ikan Bandeng memiliki rasa yang gurih, rasa daging kenyal. Ikan Bandeng digolongkan sebagai ikan berprotein tinggi dan berlemak rendah. Pengasapan menjadi salah satu metode pengawetan yang dapat diterapkan pada ikan bandeng. . Pengasapan dengan asap cair lebih praktis dan mengandung senyawa fenol, karbonil dan asam organik. Asap cair modern yang digunakan yaitu asap cair bambu tabah (Gigantochloa nigrociliata Buse-Kurz). Tujuan dari penelitian ini adalah untuk mengetahui pengaruh konsentrasi asap cair dan suhu pemasakan yang berbeda terhadap mutu se’i bandeng. Metode yang digunakan adalah Rancangan Acak Lengkap Faktorial dengan dua faktor. Faktor pertama adalah konsentrasi asap cair, terdiri dari 4%, 6% dan 8%. Faktor kedua adalah suhu pemasakan, terdiri 60oC, 80oC, dan 100oC. Kombinasi perlakuan terbaik adalah pada konsentrasi asap cair bamboo tabah 8% dan suhu pemasakann 100oC, dengan pemanasan selama 4 jam menghasilkan pH 5,5, kadar air 50,70%, kadar abu 2,70%, kadar protein 15,91 %, uji skoring kenampakan 4,67, uji skoring bau 4,67, uji skoring rasa 4,53, dan uji skoring tekstur 4,67. Milkfish has a savory flavor, a taste of chewy meat. Milkfish is classified as a high-protein and low-fatty fish. the fumigation are one of the methods of preservation that can be applied to milkfish. Fumigation with liquid smoke is more practical and contains compounds of phenol, carbonyl and organic acids. Liquid smoke comes from stem of tabah bamboo (Gigantochloa nigrociliata Buse-Kurz). the purpose of this research is to know how the effect of liquid smoke with various concentrations and the different of temperature cooking towards quality se’i of milkfish. the used method is complete random planning within two factors. the first factor is the concentration of liquid smoke, consisting of 4%, 6%, and 8%. the second factors is the cooking temperature, consisting of 600C, 800C, and 1000C. the best combination of treatment is 8% concentration liquid smoke and temperature of cooking is 1000C during 4 hours result pH 5.5, content moisture 50.70%, ash 2.70%, protein 15.91%, visibility 4,67, aroma 4,67, taste 4,53, and texture 4,67.

Tuna has a high protein and water content, and has solid meat. But tuna is also very easy to damage. The cause of damage fish is a high water content which can cause microorganisms to multiply easily. Fumigation with liquid smoke is safer and more practical than conventional fumigation, because liquid smoke contains phenol, carbonyl and organic acids which are useful for providing a distinctive taste and as preservatives in fish. The liquid smoke comes from stem of tabah bamboo (Gigantochloa nigrociliata Buse-Kurz). The purpose of this study was to determine the effect of temperature and heating time on the characteristics of processed tuna which soaked in liquid smoke stem of tabah bamboo and to find out the temperature and heating time of the best organoleptic characteristics of processed tuna which soaked in a solution of liquid smoke stem of tabah bamboo. The method used is Factorial Completely Randomized Design with two factors. The first factor is the treatment of heating temperature which consists of three levels, and the second factor is the treatment of heating time which consists of three levels. Each treatment was repeated twice. The best combination of treatments is the heating temperature of 100?C, heating for 4 hours produce pH 5.5, water content 58.06%, ash content 1.69%, protein content 18.29%, hedonic color test 3.94, aroma test hedonic 4.28, hedonic texture test 4.72, hedonic taste test 4.5, texture scoring test 4.83, and the overall acceptance scoring test is 4.39.

The purpose of this study was to determine the effect of spacing on the growth and yield of spinach plants with hydroponic NFT (Nutrient Film Technique) and to determine the most effective spacing and spinach results of hydroponic NFT plant growth. This study uses a Completely Randomized Design (CRD) consisting of four treatment spacing, namely 5 cm, 10 cm, 15 cm and 20 cm. Each treatment uses the same number of plants as 15 plants in one gutter. The study was conducted for 20 days. The parameters observed were plant height, number of leaves, fresh weight, dry weight, root length, and stem diameter. High parameters and number of leaves are measured every two days, while parameters of fresh weight, dry weight, root length, and stem diameter are measured after harvest on the 20th day. For the final value obtained from the calculation of plant height growth parameters, namely JT5 (27.45), JT10 (32.45), JT15 (33.22), and JT20 (32.94). And for the final value obtained from the calculation of the number leaf growth parameters, namely JT5 (11.21), JT10 (12.19), JT15 (12.51), and JT20 (12.17). While the final value of crop yield parameters for root lengths is JT5 (28.06), JT10 (30.43), JT15 (31.36), JT20 (30.70). For the stem diameter the average value obtained is JT5 (0.72), JT10 (8.84), JT15 (0.90), JT20 (0.85). For fresh weight of plants, the average values ??obtained are JT5 (182.40), JT10 (208.24), JT15 (215.07), JT20 (210.76). And for dry weight, the average value obtained is JT5 (9.51), JT10 (13.52), JT15 (15.05), JT20 (13.71). It can be concluded that from the results of the ANOVA analysis, the treatment of 15 cm spacing had the best results and the spacing of 5 cm showed the lowest results in each treatment observed.

The purpose of this study was to determine the effect of using brine with different types of salt on cooling fish and its effect on cooling load, so that a combination of treatments that produced the lowest cold point and maximum ability were obtained to eliminate the total heat energy in fish. The raw materials used in this study are salts of NaCl, KCl, CaCl2 and tuna. The cooling process in this study uses ice and salt (brine) solutions with concentrations of each type of salt, namely 2%, 7%, and 12% of the weight of the cooling media. In this research, the first two stages were carried out, namely with air load, then continued with the hot load of fish for each cooling medium on different styrofoam boxes. From the results of this experiment, a decrease in the maximum cooling point of brine temperature of -2,46 °C was found in the treatment of NaCl salt concentration of 12% (a1b3), then brine solution which was able to keep the fish temperature at the lowest is -1.4 ° C from treatment a1b3 (NaCl salt) concentration of 12%.

Erodibility of the soil is the sensitivity of the soil to erosion, the higher erodibility value of the soil the easier the soil erodes. One way to reduce the rate of erosion is by covering the soil with mulch. The purpose of this study is (1) to know the effect of plastic mulch and straw on the cultivation of tomato plants on the level of soil erodibility and (2) to know the type of mulch which gives the lowest soil erodibility level in tomato cultivation. The design in this study uses a Completely Randomized Design with treatment consisting of tomato plants planted without mulch, tomato plants planted using black plastic mulch, tomato plants planted using silver plastic mulch, tomato plants planted using transparent and tomato plants planted using straw. The results showed that the treatment without mulch and treatment with straw had increased erodibility values, while the treatment using black plastic and using silver plastic had decreased erodibility value. In the treatment with transparent mulch there is no effect in erodibility value. Each treatment had different values but had the same level of category, which is very high. The type of mulch who had the lowest value is the treatment silver plastic mulch with an erodibilitas value of 0,58 at the beginning of cultivation and 0,55 at three months of planting age. Keywords: Soil erodibility, tomato plants, mulch.
