Abstract

Andini A, Cahya A, Ningsih AO, Iqbal M, Sugiarti S, Fitrani M.  2021. Intensive system fish farming waste conversion to biogas household scale. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang  20 Oktober 2021. pp. 400-410.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Intensive system fish farming with high protein artificial feeding in a limited scope produces waste that can negatively impact if it is directly discharged to the waters. This study aimed to examine whether intensive fish farming waste can be converted into biogas, especially on a household scale, as an alternative in processing aquaculture waste. The method used by the researcher in the literature review method is due to the Covid-19 pandemic situation, which limits researchers from taking data. The results of the literature study state that aquaculture waste has the potential for methanogenic bacteria as the main component of biogas with an anaerobic decomposition process. The content of nitrogen (N2) and hydrogen sulfide (H2S) in aquaculture waste is also an additional component in biogas production. Household-scale biogas production was formed on day 4‒30 which consists of several processes such as hydrolysis, acetogenesis, acetogenesis, and methanogenesis. Biogas production results from fish farming waste can also be used as organic fertilizer for plants or agricultural land. Therefore, converting fish farming waste into biogas can be done as an effort to treat aquaculture waste. Suggestions from this research are necessary to re-examine directly in producing biogas to obtain more relevant data.

Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Maize is one of the most important staple crops in East Nusa Tenggara (ENT). Maize is widely grown on dryland as food crop or animal feed. However, its productivity at both regency and provincial levels is still lower than the national average. One of the solution to increase maize productivity is using superior varieties such as Nasa-29 hybrid varieties which has high productivity. The purpose of this study was to examine the opportunities of using Nasa-29 hybrid maize to increase maize productivity in ENT. The study was carried out in Oeteta Village, Sulamu District, Kupang Regency. The study was carried out by making a Nasa-29 hybrid demonstration farm (demfarm) on 20 hectares dryland which spread over 5 farmer groups. During the 2019’s Dry Season (DS) demfarm covering an area of 7 hectares and 13 hectares on the 2020’s Wet Season (WS). Growth and production data were collected and analyzed statistically using Least Significant Difference (LSD) test at 5% level to exemine the significance of differences between the treatment means. Data of productivity, costs, and net income were used to calculate the B/C ratio. The results of the study showed that the production of hybrid maize in WS and DS was not significantly different based on the LSD test at the 5% level. Nasa-29 hybrid maize can increase productivity up to 181% compared to the existing condition  (2.59 t/ha) which were up to 189% on WS and 176% on DS. The B/C analysis showed that hybrid maize farming system was feasible (B/C ratio value > 1) which were 1.35 on DS and 2.65 on WS. So, it can be concluded that Nasa-29 hybrid maize potentially to increase corn production in ENT.

Abstract

Hasdevi H.  2021. The crime of forest and land burning conducted by corporations to start a plantation business. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang. 20 Oktober 2021. pp. 628-639. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Corporations starting new arable land by burning forests is the easiest and cheapest way to do. If there occurs a forest fire as the result of plantation clearing, it can  cause environmental damage, disruption of public health, educational activities, economy, and transportation. The purpose of this study was to find out the effects of the prevailing laws and regulations on forest burning behavior conducted by corporations in opening new arable land. The method used in this study was normative juridical, descriptive analytical, using the Legislation approach. To live and have a good and healthy living environment is the right of the community, as stated in the Article 28 h paragraph (1) of the 1945 Constitution of the Republic of Indonesia. In addition, the perpetrators of the crime of forest burning are regulated in: the Law Number 41 of 1999 in conjunction with the Law Number 19 of 2004 concerning forestry, The Law Number 32 of 2009 concerning Environmental Protection and Management, The Law No. 39 of 2014 concerning Plantations, The Criminal Code and Supreme Court Regulation Number 13 of 2016, apparently have not been able to provide a deterrent effect for perpetrators of corporate crimes to burn forests and land. In addition, the application of selective slashing law still often occurs in the Indonesian legal community. The perpetrators of corporate crimes repeatedly burning forests should be carried out through a criminal law approach, civil law in the form of compensation in totality and administrative law in the form of revocation of business licenses. The application of the law that is not selective should be a guide in enforcing the laws and regulations.

Misbah M, Aulia JP, Maharani M, Widhiastuti E, Putri VMW, Ardila S, Tanbiyaskur T. 2021. Potency of lemongrass stem extract (Cymbopogon citratus) for Fish Treatment from Edwarsiella tarda bakteri bacteria. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang  20 Oktober 2021. pp. 782-787. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).  The high demand for fishery products has resulted in cultivators implementing intensive and even super intensive cultivation systems. The intensification of fish farming is characterized by an increase in stocking density followed by an increase in the use of artificial feed which has the potential to become waste and cause disease. To overcome this, alternative actions that are safer and also effective for controlling fish diseases are needed. One alternative is to use herbal plants that are anti-bacterial. By using herbal plants, it will be safer, easier to obtain and also not pose a danger to the surrounding environment. This study aimed to determine the effectiveness of lemongrass stem extract to treat bacterial disease in fish caused by Edwarsiella tarda. Some research results showed that Cymbopogon citratus extract is rich in benefits in herbal medicine. Cymbopogon citratus extract had antibacterial properties that could inhibit the growth of pathogenic bacteria in fish. Phytochemical test results, lemongrass extract contained secondary metabolites such as alkaloids, steroids, terpenoids, phenolics or tannins or flavonoids and saponins. Based on the results of in vitro tests on lemongrass stem extract, it was able to inhibit the growth of Edwarsiella tarda bacteria where the inhibition zone formed after the media was incubated for 24 hours with a size of 21 mm. This proved that lemongrass stem extract can inhibit the growth of Edwarsiella tarda bacteria based on the results of the inhibition test.
