Abstract

Indonesia is the third largest cocoa (Theobroma cacao L.) producing country in the world. In 2019 cocoa production in Lampung was 58,852 tons with a plantation area of 79,356 ha, in 2020 it was 58,623 tons with an area of 79,469 ha and in 2021 58,414 tons with an area of 77,174 ha. One of the reasons for this decline in production is plant pest organisms (OPT), namely fruit rot disease caused by the pathogen Pytophthora palmivora. Use of Trichoderma sp. can increase plant resistance and growth and act as a biological controller outside and inside the soil. The research was carried out on the grounds of the Lampung State Polytechnic from August to November 2023. This research aims to determine the effect of planting media and administration of Trichoderma sp. on the growth of cocoa seedlings. The method used was a Randomized Block Design (RAK) with 4 treatments and 4 replications so that there were 16 experimental units. Treatment P0 consisted of: Top Soil (Control), P1 Top Soil + Compost Fertilizer (2:1), P2 Top Soil + Trichoderma sp. (50:1), P3 Top Soil + Compost + Trichoderma sp. (50:25:1). The results of the research on treatments P3, P2 and P1 affected plant height, number of leaves and stem diameter. The P3 treatment showed the best results for the variables plant height 39.50 cm, number of leaves 21.58 and leaf area 37.79 cm2. Treatment P2 showed the best results for the stem diameter variable of 0.66 cm.

Abstract

Mucuna pruriens also known as velvet bean (koro benguk) is a plant commonly found in tropical regions, including Indonesia. Mucuna pruriens is known to contain high levels of Levodopa, making it a potential natural treatment for Parkinson's disease. Parkinson's disease is a neurodegenerative disorder characterized by tremors, rigidity, bradykinesia, and postural instability. The estimated global incidence of Parkinson's disease in 2024 is expected to reach 12 to 17 million patients. Synthetic Levodopa has been the standard and proven effective therapy for Parkinson's disease. The method used in the preparation of this article is a literature review by collecting relevant and focused articles. The literature sources were accessed through comprehensive searches in three databases (Pubmed, Google Scholar, and Researchgate) from 2014 to 2024, using keywords such as “Mucuna pruriens,” “Levodopa,” and “Parkinson's disease.” The result of the literature review indicates that Levodopa is the dominant active component found in Mucuna pruriens compared to other compounds. The naturally occurring Levodopa functions as a precursor to dopamine, which plays a role in the treatment of Parkinson's disease, thus it can be developed into a complementary therapy in regions with abundant resources.

Abstract

Larvae of the Black Soldier Fly (BSF) are a natural material that has the potential to become a new alternative for accelerating wound healing due to their nutritional content. This study aims to analyze the potential of BSF larvae oil ointment in accelerating the healing of incisional wounds in mice. The study was conducted as an experimental research with six treatments and four repetitions, including a control group without treatment, ointment base, gentamicin ointment, BSF larvae oil ointment at 5% concentration, BSF larvae oil ointment at 10% concentration, and BSF larvae oil ointment at 15% concentration. The parameters observed included the percentage of wound healing, area under the curve (AUC) values, and anti-inflammatory efficacy percentage. The results showed no significant differences between groups based on statistical analysis (P>0.05) for the observed parameters. However, the 5% BSF larvae oil ointment showed a 100% healing percentage on the fourteenth day. Based on AUC values and anti-inflammatory efficacy percentage, the 5% BSF larvae oil ointment had values close to commercial gentamicin ointment. This indicates that treatment with BSF larvae oil ointment, especially at the lowest dose, plays a role in accelerating incisional wound healing and has great potential to be developed as a commercial ointment in the future.

Abstract

The palm flour manufacturing industry produces a lot of liquid waste and solid waste. The absence of a waste processing system means the waste is dumped around the production house. The large amount of solid waste that is dumped every day causes a buildup of waste on riverbanks. The flow of river water is disturbed, pollutes the river ecosystem, and the smell is unpleasant. The research aims to identify the content of N, P, and K elements in palm flour solid waste. The data obtained will be used as a basic reference for using palm flour solid waste as an alternative compost material considering that most of the Pucang Miliran village area is an agricultural area. The research was carried out by taking a sample of 1 kg of sugar palm flour solid waste and testing it for the content of N, P, and K. Data from laboratory tests were analyzed descriptively supported by a literature study. The research results showed that palm flour solid waste contained Nitrogen (N) of 194.227 mg/Kg, Phosphorus (P) of 410.270 mg/Kg, and Potassium (K) of 832.382 mg/Kg. The presence of the three nutrients N, P, and K in large enough quantities can be considered that palm flour solid waste can be a good alternative material for making organic fertilizer/compost. Further research is needed to determine the comparison and combination of various compost material compositions to produce the best palm solid waste compost.

Abstract

White shrimp (Litopenaeus vannamei) is an important aquaculture commodity with production demand that continues to increase every year. The addition of chitosan from green mussel shells in feed can increase calcium availability, support the moulting process, and increase shrimp growth and survival. This study aims to examine the effectiveness of green mussel chitosan supplements on the growth and survival of vaname shrimp. This research consists of three stages, namely making chitosan nanoparticles from green mussel shells, making feed with various doses of chitosan nanoparticles (0%/A, 10%/B, 15%/C, and 20%/D), and cultivating vaname shrimp. Feed is made by mixing chitosan nanoparticles with commercial feed, then drying and crushing it into small crumbs. White vaname shrimp are kept in concrete ponds for 80 days, with water quality monitoring and regular measurements of growth in weight and length. Data shows that C treatment with a dose of 15% chitosan nanoparticles resulted in the highest growth in weight and length of vanamei shrimp, reaching an average weight of 12.58 grams and a length of 14.07 cm on the 80th day. Treatment C provides optimal growth compared to other treatments because chitosan accelerates the moulting process and exoskeleton mineralization. Water quality during the study, including a temperature of 29.99°C, pH 7.23, and ammonia content of 0.25 ppm, was within the tolerable range for shrimp growth.

Abstract

Cemeteries are a form of green open space (GOS) that are commonly found in various landscapes, both urban and rural.  Its existence becomes a balancer in an environment. However, studies on the ecological role of cemeteries are still very limited, including its role as bird habitat. This study aims to analyze the role of cemetery open space as bird habitat in Cimahi City, West Java Province. The research was carried out in May-June 2021 and May 2022 at 23 cemeteries. Bird data was taken using the cruising method while habitat data described conditions in general. Data were analyzed by qualitatively and quantitaively (chi-square, diversity index, evenness index, and similarity index). The richness of bird species found was 23 species birds. The birds species found varied from only two species (Al Maqom, Cibaligo, Cibaligo Tengah, Kihapit, and Melong RW07) to 13 species of birds (Gunung Bohong). The most widely distributed bird species is the Cave Swiftlet (All locations) followed by the Eurasian Tree Sparrow (18 locations), while six species are only found in one location.  The number of species found differed significantly between cemetery sites (χ²count = 39.90; df=21; P<0.05), as well as the number of individual birds (χ²count = 1659.82; df=21; P<0.05).  The diversity index ranged from 0.50 (Cibaligo) to 2.44 (Gunung Bohong), while the evenness index ranged from 0.66 (Cibodas) to 0.99 (Kihapit).  The similarity index ranged from 0.07-1.00.
