Rice productivity in tidal lands can be achieved by using local resources, including managing rice straw as a biological organic fertilizer (POH). The biological organic could be used with ingredients rice straw: chicken manure: Azospirillum bacteria, and Phosphate Solvent Bacteria (6:4:1). These can increase soil fertility, nitrogen, and phosphorus and potassium nutrients through the activity of microorganisms (Azospirillum and Phosphate Solvent Bacteria). This study aims to obtain the right dose of POH to increase rice production in tidal soils. This research was carried out in an experimental garden, using tidal soil media type C overflow from Banyuurip Village, Banyuasin Regency. Testing using field experiments. The layout used a Randomized Group Design with 4 treatments repeated 6 times, namely POH (D) doses: 0 kg/ha (D0), 200 kg/ha (D1), 400 kg/ha (D2), 600 kg/ha (D3). The best results were found in using POH with a dose of 600 kg/ha, which was 41.67 g / plant and increased production by 87.96% compared to without POH.

Tofu is one of the foods in great demand by the public with affordable prices and fulfils the needs of protein in the body. The main obstacle to tofu production is concise shelf life. Tofu has a shelf life of one to two days without preservatives even though it is stored at a low temperature, which is a maximum temperature of 15°C. The way to reduce food ingredients' damage could be using natural origin and synthetic preservatives. The crown of god fruit can be used as a preservative of food from nature because it contains antioxidants and antimicrobials. This study aims to determine the Total Plate Count (TPC) of tofu stored with the fruit flour of the crown of god fruit. The method used is a Non-Factorial Group Randomized Design (RAK) consisting of six levels of treatment and repeated four times. The soaking of tofu in various powders of god's crown fruit as a natural preservative has a very noticeable effect on the Total Plate Count (TPC) after five days of storage. The highest number of microbes in the M0 treatment (without the provision of god's crown fruit flour) with an average value of 2.73x102 CFU/g and the lowest number of microbes in the M4 treatment (0.125g) with an average value of 0.93x102 CFU/g.

Tobacco is an important commodity in Indonesia because the tobacco industry makes a significant contribution to the Indonesian economy. Tobacco plants need nutrients to grow optimally. One source of nutrients for soil media is compost made from coffee grounds. These coffee grounds are often found as waste from the many coffee shops in Yogyakarta. The purpose of this study was to determine the effect of organic fertilizer made from coffee grounds on soil fertility and the growth of Vorstenlanden tobacco plants on different compositions of growing media. This research was carried out using a non-factorial completely randomized design with 5 levels A0 (Without giving coffee grounds compost), A1 (53 gr compost), A2 (105 gr compost), and A3 (158 gr compost), A4 (210 gr compost). The results showed that the administration of coffee grounds compost with the lowest amount gave the highest growth pattern compared to the treatment with the high amount of coffee grounds compost, and the application of coffee grounds compost did not show a significant increase compared to the treatment with coffee grounds compost. Compost of coffee grounds fermented for 2 weeks should not be applied to Vorstenlanden tobacco plants.

This study aims to determine the influence of the location of the buds and mechanical treatment after grafting on the growth of orange seedlings. The study used a Randomized Group Design (RAK), arranged factorially with nine combinations of treatments and three tests. The first treatment factor used is the budding eye system (P), consisting of 3 levels, namely P1: Fourth Budding Eye; P2: Fifth Budding Eye; and P3: Sixth Budding Eye. The second factor is mechanical treatment after grafting (K) consisting of 3 levels, namely K1: Rootstock Cutting; K2: Rootstock Restraint; and K3: Rootstock Bending. The parameters observed are the percentage of grafting of living plants, the time of bud exit, the number of leaf blades, the twisting of the stem of the grafting bud, and the length of the grafting bud. Based on the observations on the percentage of grafting that live after mechanical treatment of all budding eye location treatments, it shows that the fifth bud (P2) location treatment gives a higher rate of live grafting, which is 100% compared to other treatments. The treatment of the location of the fifth bud gives the best results against the time of bud exit, the number of leaves, the twisting of the grafting stem and the length of the grafting bud. Mechanical treatment of rootstock restraint after grafting gives the best results against the time of bud exit, the number of leaves, the twisting of the grafting stem and the length of the grafting bud. The interaction between the treatment of the fifth bud location treatment and the mechanical treatment of rootstock holding gave the best results against the growth of Siamese orange seedlings.

The state of sugar in Indonesia which is decreasing in terms of production, the imbalance between production and consumption, can occur due to two things, both on-farm and off-farm. Planting in monoculture for a long period of time will cause reduced soil fertility conditions so that sugarcane productivity decreases. Sustainable nutrient management in sugarcane plantations is an effort made to obtain optimal and profitable productivity, while still trying not to damage the environment so that it can be sustainable and its productivity can be maintained in the long term. Several concepts for sustainability have been put forward by many experts, including the use of site-specific fertilizers, maintaining soil fertility by using sugar processing by-products and the use of humic. It is hoped that some of these application methods can maintain sugarcane plantations to be sustainable.

Residents use the Komering tributary that flows through Pangkalan Gelebak Village in Banyuasin Regency for fish farming activities. Villagers tried to cultivate catfish and tilapia, but it did not work because they died. Water as a medium for fish farming activities is an important factor that must be considered. Water quality in waters can affect aquaculture activities and fish growth. The study was conducted to determine the water quality (physics and chemistry) in the Komering River tributary as a basis for the cultivation environment. The research was conducted in the Komering tributary of Pangkalan Gelebak Village, Banyuasin Regency, in September, October, and November 2019. The sampling point is determined using a purposive sampling method in four sampling points. The temperature measurements range from 27-32.7ºC, depth 0.4-9 m, brightness 0.2-1.1 m, and turbidity 12.62-69.2 NTU. Only the depth of the four physical parameters is unsuitable for cultivation activities. During the dry season, the water depth between the riverbed and cage nets does not reach 1m. Chemical parameter measurement results; dissolved oxygen 1.7 – 7 mg/l, pH 6.5 – 7, alkalinity 34 - 46 mg/l CaCO3, nitrate 0.892 - 2.278 mg/l, nitrite 0.032 - 0.217 mg/l, ammonia 0.02-0.398 mg/ l and ortho-phosphate 0.054-0.283 mg/l. The value of nitrate, ammonia, and orthophosphate indicated high values so than unsuitable for fish farming activities. Agricultural activities around creeks and domestic waste disposal are causes of poor water quality.

The combination of these treatments used two Complete Compound Fertilizer Formulas (P). Formula 1 (P1) Complete Compound Fertilizer Pril (PMLP), 2 (P2) : Complete Compound Fertilizer Tablets (PMLT), and 3 (P3) as a control mixture of single fertilizer Urea, SP 36, and KCL ( 1:1:1). The second formula is fertilizer dosage (D) which consists of three levels, namely D1 (30 g fertilizer/plant), D2 (40 g fertilizer/plant), and D3 (50 fertilizer/plant). The variables observed in this study were plant height, number of fruit per plant, fruit weight per plant, dry weight of plant stover. Based on the results of the research that has been carried out, it is concluded that the treatment of Complete Compound Fertilizer Formula (P) has a very significant effect on all observed variables, namely: plant height, number of fruits per plant, the weight of dry root, and weight of fruit per plant. While the Fertilizer Dosage (D): 30, 40, and 50 g did not show a significant difference in the results for all observed variables, and the interaction between the two did not show significant differences in all observed variables.
