Putri AAE, Rahma BS, Anggraini L, Azizah M, Asyarifah MR, Fitrani M. 2021. Bumina cultivation technology uses a raft system water flow. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 524-529. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI). Fish farming is one of the livelihoods in Indonesia. The number of people as actors of fish cultivation such as freshwater fish, but is constrained by increasingly limited land, decreasing water quality and quantity, water pollution and the impact of intensification. Therefore, a solution is needed to overcome this problem, namely by making use of a pond called the BUMINA (fruit and fish) pond that uses a raft system water flow. Bumina Pond is a pond that not only produces freshwater fish but is also able to produce certain fruits by utilizing freshwater fish farming on simple land and relatively cheap costs. fruit. The results obtained from Bumina's cultivation are fish, besides that it also produces fruit that increases income.

The combination of making organic liquid fertilizer from the offal waste of tuna fish (Euthynnus affinis) with probiotics as an effort to optimize plant growth. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembng 20 Oktober 2021. pp. 660-669. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Tuna fish (Euthynnus affinis) was a type of pelagic fish that had economic value. Catching dan managing tuna produced waste that was directly discharged into the environment, resulting in unpleasant odors dan causing the environment to became polluted. One alternative way was that the waste could be utilized by making liquid organic fertilizer. This study aimed to utilize the waste of tuna fish innards (Euthynus affinis) using the EM4 fermentation method which could be an alternative to liquid organic fertilizer for plant fertility. The writing method in this study used study of literature. The results of this study showed that addition of liquid organic fertilizer from fermented waste fish gave the enhancement nutrition for the soil. The increase in nutrient levels in the soil triggered an increase in lateral root length, stem diameter, fresh weight dan dry plant weight. The application of organic liquid fertilizer from fermented fish made effects on increasing soil porosity, reducing soil density dan triggering the production of auxin substances that increase lateral root growth. Therefore, the manufacture of organic liquid fertilizer from fermented tuna (Euthynnus affinis) accelerated plant growth dan along with its used could reduce fish offal waste.

Fikri M. 2021 The use of clarifier tank technology in wastewater treatment of the palm oil industry. In: Herlinda S et al (Eds), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 803-810. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI). The palm oil industry has both positive and negative impacts on society and the environment. The positive impact is increasing the country's foreign exchange and public welfare, while the negative impact is creating waste that can pollute the environment if it is not managed properly. This study aimed to purify oil palm wastewater which was generally cloudy in color due to the high content of organic matter. This study used a clarifier tank that is installed after the last pool at the Outlet of the Wastewater Treatment Plant before the wastewater is discharged into the water body. The results were obtained using the clarifier tank technology (settlement tank) by combining the chemical processes (coagulation, flocculation) and physical processes (sedimentation) in one tank unit, which can reduce the total suspended solids (TSS) content in wastewater. The process of purifying wastewater which was originally cloudy in color so that it is safe to be discharged into surface water bodies using several types of chemicals. The types of chemicals used in the precipitation process were soda ash and alum. The soda ash or sodium carbonate served to adjust the pH in the range of 6-7. The alum functioned as a coagulant, namely to agglomerate dirt so that it settled at the bottom of the clarifier tank. The use of clarifier tank technology at the Outlet of the Palm Oil Industry Wastewater Treatment Plant is not only beneficial for humans, but also has a good impact on the surrounding environment, including animals and plants.

The effect of intercropping chili with cabbage on pests and plant disease in Kerinjing Village Pagar Alam city. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp.101-113. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Red chili (Capsicum annuum) belongs to the family Solanaceae and is one of the vegetable commodities that has many benefits, high economic value. The aim of this field practice is to find out the difference in intensity of pest and disease attacks on intercropping and monoculture chili plants. This field practice was carried out in Kerinjing Village, Dempo Utara District, Kota Pagar Alam, South Sumatra. The reseach uses the case method by deliberate sampling in a field by counting the number of mounds in the field and determining the sample on the mound to be observed. On the two fields that were observed were found pests and diseases that attacked the chili plants namely mandibular pests and curly diseases, yellow disease and leaf spot disease. The average intensity of mandibular pest attacks on monocultures is 2.7% while on intercropping is 11.12%. The mean intensity of attacks of curly diseases was 33.87% in monocultures and 22.35 in intercropping. In jaundice, the mean intensity of attack was 14.87% in monoculture land and 8.25% in intercropping land while the mean intensity of spotting was 5.67% in monoculture land and 1.30% in intercropping land. From the observations that have been made that there is no significant difference between monoculture land and intercropping land for pests and diseases of chili plants. Weather affects the attack of pests and diseases on both fields, where dry weather affects the spread of disease-causing vectors so that the intensity of the attacks is higher. And also the use of crop rotation that is not right also exacerbates the level of pest and disease attacks on chili plants.

Strategi yang tepat dalam Pengendalian Hama Lalat Buah (Bactrocera sp.) pada Tanaman Jambu Air Hijau Deli (Syzygium aqueum). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 242-248. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Deli green water guava (Syzygium aqeum) is one of the agricultural products in Indonesia that has high economic value. Many pests, are pests for this plant, one of which is fruitfly. Fruitfly (Bactrocera sp.) have 400 species with different levels of attack in each species. Cultivation of this green water guava fruit is very profitable for farmers and can improve their economy. Fruit farmers generally still depend on synthetic pesticides to control fruitfly, even though this method can pollute the environment and the resulting plant products. This review aimed to identify and overcome fruit fly pests that attacked deli green guava with proper control and attention to all aspects. This writing is based on a study of the literature taken and then analyzed and developed into a review that is easy to understand. Fruit fly pest control is usually done by wrapping fruit using plastic. However, farmers are often reluctant to use this method because of the large number of fruits to pack. Another more effective way is to use vegetable insecticide control by using methyl eugenol. It was concluded that the fruit fly pest attack can damage the quality of the green water guava fruit which has an impact on the selling value, so effective control must be used such as the use of methyl eugenol.

Yunita D. 2021. Metal cadmium absorption using extracted and unextracted lignite coal with organic solvents. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 482-489. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Lignite coal with a large surface area, having carboxylate and phenol functional groups can be used as cadmium metal adsorbent, but the impact of lignite coal extraction on the absorption of cadmium metal content using organic solvents needs to be investigated. This study aimed to find out the adsorption power of cadmium metal ions by lignite coal extracted using the best organic solvents and without extraction at optimum absorption conditions.The extraction method was soxhletation using n-hexane, chloroform, and ethanol as solvents. The measurement of cadmium metal content was determined by the Atomic Absorption Spectrometry (AAS) method, where the optimum conditions for the absorption of cadmium metal ions were determined by varying the stirring time (3, 8, 15, 30, 45, 60 minutes), pH (2, 3, 4, 5, 6, 7), and metal ion concentration of cadmium (1, 3, 5, 7, 9 ppm). The results of the study showed that the adsorption ability of lignite coal extracted with ethanol was higher than the other solvents used. The optimum conditions for absorption by the extracted adsorbent were reached at 60 minutes, pH 7, and a concentration of 9 ppm while the adsorbent without extraction was reached at 60 minutes, pH 5, and a concentration of 9 ppm. The absorption of cadmium metal ions produced by each adsorbent extracted and without extraction was 0.1668 mg/g and 0.1674 mg/g.Thus, the lignite coal without extraction is the most suitable as cadmium metal adsorbent. Further research is needed on the pore size of the extracted lignite coal and the functional groups present in the lignite coal in the adsorption process.

Addition of liquid organic fertilizer from coffee grounds as nutrients in a hydroponic system on the growth of lettuce (Lactuca sativa L). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimalke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 891-899.Â Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Â Hydroponics is a way of growing without using soil media which generally uses AB mix nutrients as inorganic fertilizer for plants. In order to reduce the use of sustainable hydroponic basic nutrients, an alternative nutrient source is added in the form ofPOC (Liquid Organic Fertilizer). One of the ingredients used in making POC is coffee grounds. The purpose of this study was to identify the potential of Liquid Organic Fertilizer (POC) from coffee grounds as a nutrient enhancer in a hydroponic system for the growth of lettuce (Lactuca sativa L.). It is suspected that the use of POC coffee grounds contains nitrogen and phosphorus which can help your plants grow faster and fertile. This study used coffee grounds fermentation which was used as POC according to the composition contained in the literature journal as a nutritional enhancer on lettuce growth, as well as the effect given by the POC. Coffee grounds contained 2.28% nitrogen, 0.06% phosphorus and 0.6 potassium. The pH of coffee grounds was slightly acidic, around 6.2 on the pH scale. In addition, coffee grounds also contained magnesium, sulfur, and calcium which were useful for plant growth. The treatment of liquid organic fertilizer (POC) from coffee grounds had an effect on the growth of lettuce plants on all variables, namely the number of leaves (strands), leaf length (cm), leaf width (cm), plant height (cm), and root length (cm). Giving POC with the same concentration in each plant gave significant results in plant height. From the results of the study, it can be concluded that coffee grounds can be used as a nutrient enhancer for the growth of lettuce (Lactuca sativa) with hydroponic media.
