Abstract

Indonesia merupakan salah satu negara dengan keanekaragaman tumbuhan yang tinggi. Potensi tumbuhan yang ada belum diberdayakan secara maksimal oleh masyarakat, khususnya di Kebun Raya Liwa. Banyak tumbuhan yang memiliki potensi sebagai tumbuhan obat, namun penggunaan sebagai pestisida alami belum banyak digali lebih lanjut. Keterlibatan staf yang ada di KRL sangat diperlukan untuk memanfaatkan secara langsung tumbuhan yang ada untuk membuat pestisida alami. Pestisida alami ini dapat digunakan untuk mengendalikan penyakit yang disebabkan oleh jamur (fungisida), mengendalikan gulma (herbisida), maupun mengendalikan tikus (rodentisida) dan lain sebagainya. Oleh sebab itu perlu dilakukan pelatihan untuk membuat pestisida alami bagi staf Kebun Raya Liwa. Kegiatan Pengabdian Kepada Masyarakat (PKM) ini bertujuan untuk meningkatkan pengetahuan dan ketrampilan dalam pembuatan pestisida alami dengan metode maserasi. Hasil dari pelatihan ini menunjukkan ada peningkatan pengetahuan dan keterampilan dengan peningkatran nilai post-test sebesar 29 poin, perentase peningkatan sebesar 64,44%. Hasil dari kegiatan Pengabdian Kepada Masyarakat ini staf Kebun Raya Liwa dapat membuat pestisida alami dan dapat menggunakan pestisida alami untuk mengendalikan organisme pengganggu yang ada di Kebun Raya Liwa.

Abstract

Financial performance serves as information for investors and policymakers who support the implementation of company operations. Financial performance can be measured using financial ratios. This research aims to (1) find out and analyse the effect of the Current Ratio on Return on Asset, (2) know and analyse the effect of Debt to Assets Ratio on Return on Asset, (3) determine and analyse the effect of Total Asset Turnover on Return on Asset. This study uses a sample of automotive sub-sector companies listed on the IDX during the period 2016-2022. There are 12 state-owned companies listed on the IDX. A total of 9 automotive subsector companies were used as samples in this study. The sampling technique used in this research is purposive sampling. Data collection techniques use documentation techniques with secondary data. Data analysis technique The results showed that the Current Ratio (CR) variable partially did not have a significant effect on Return on Assets (ROA). The current Ratio (CR) variable partially has no significant effect on Return on Asset (ROA). The debt to asset ratio (DAR) variable is partially variable and has a negative and significant effect on return on asset (ROA). Variable Total Asset Turnover (TATO) partially has a positive and significant effect on Return on Asset (ROA). Based on the F test, the obtained variable Current Ratio (CR), Debt to Asset Ratio (DAR), and Total Asset Turnover (TATO) variables simultaneously have a significant effect on Return on Asset (ROA) have a significant effect on Return on Asset (ROA).

Abstract

The Faculty of Mathematics and Natural Sciences (FMIPA) as one of the faculties at the University of Lampung has many trees that produce organic waste in the form of leaf litter every day, and this is very potential to be used as a substrate for compost. Compost is the final substance of a fermentation process of piles of waste/plant litter and sometimes also includes animal carcasses. In the open, compost can occur on its own, through natural processes. However, the process takes a long time while the need for fertile soil is urgent. Therefore, the process needs to be accelerated with the help of microorganisms. This community service activity is a form of application of science and technology by inducing leaf debris as compost material with saprotroph fungi inoculum. Saprotroph fungi isolates are very potential to be developed into composting inoculum in making organic fertilizers. Compost induced with this fungal inoculum is expected to produce organic fertilizer relatively quickly and contain high plant nutrients. The results of the Community Service showed quite good results, namely an increase of about 88.4% from the initial understanding. This is quite interesting because the initial understanding of compost and inoculum was relatively low at 25.04%. After the explanation given by the Community Service team, it was able to be understood by the target audience well so that their understanding increased to 63, 6%.

Abstract

Anoxygenic Photosynthetic Bacteria (APB) has beneficial properties including as probiotic candidates, biofertilizers, bioremediation agents, and can reduce H2S concentrations in waters. However, the APB also has a weakness, slow growth.It is known that the interaction of metal ions and the exposure of magnetic fields increases enzyme activity and growth rates. The aim of this study is to determine the effect of metal ions and the exposure to magnetic fields on APB growth. The APB isolate, AM which is isolated from mangrove roots and tested for its effects on metal ions in seawater complete (SWC) media.The metal ions tested were Cu, Pb, Al and Fe with different concentrations. The metal ion is exposed to a 0.2 mT magnetic field for 10 minutes before being added to the media. The cell count results showed that both metal ions exposed and unexposed to magnetic field did not affect the growth of APB AM isolates. However, the metal ion in SWC media affects the spectra pattern of AM APB isolates.

Abstract

Intensive shrimp culture has encountered many problems, such as declining water quality through disease caused by pathogenic microbes, which affected mortality. This study aimed to determine any potential probiotic from Bacillus sp. collected from mangrove in East Lampung, which could be used to improve the cultured shrimps' proteolytic and probiotic activity. This is a descriptive research with sampling and data collection of bacteria from many samples of mangrove. Result shows 128 isolates Bacillus from which then it has arrived at five potential probiotic Bacillus sp. The study five Bacillus sp. has been isolated with potential properties for probiotic (KPP212, IP121, UJ131, UJ132, SB141). Each isolate has characteristics with proteolytic property, growth in a wide range of pH 4–10 and osmotic stress (0–6% NaCl), non-pathogenic, ability for glucose fermentation, non-motile, and has negative catalase activity. The five potential Bacillus sp. can be used as probiotics for shrimp farming.

Abstract

Geographically, it is located in a strategic urban area with quite rapid development, both in terms of infrastructure development and population growth. The heterogeneous composition of its population, both in terms of education level, livelihood, and cultural background, provides both potential and challenges in efforts to create an empowered community and actively participate in sustainable environmental management. In general, most residents of Nginden Jangkungan Village work in the informal sector, such as street vendors, rental services, grocery stores, and transportation services. This is exacerbated by the community's limited technical knowledge regarding waste management based on the principles of reduce, reuse, recycle (3R), as well as the absence of an integrated and sustainable empowerment model. The implementation method of this Community Service activity is designed with a participatory and collaborative approach, prioritizing synergy between academics, the village government, community groups, and beneficiary residents. Nginden Jangkungan Village has adequate social and institutional potential to implement a civil society empowerment program in sustainable environmental management. However, this area still faces serious challenges related to the management of household liquid waste, which has not been handled optimally, so it has the potential to pollute groundwater and waterways and cause environmental health impacts.
