Abstract

Calliandra biomass pellets offer a promising alternative energy source to replace fossil fuels. Typically, these pellets are produced by directly processing the stem and bark of the calliandra (Calliandra calothyrsus) plant without separation, aiming for manufacturing efficiency. This study investigated the quality differences between calliandra biomass pellets with and without bark and varying particle sizes. Particle sizes used were 20 mesh, 40 mesh, and 60 mesh. The pellets were made using a 12 mm diameter biomass pellet mold and a manual hydraulic press with a pressure of 3 tons. Characterization involved assessing proximate analysis, calorific value, physical and mechanical properties, and Fourier Transform Infrared analysis. The test results were compared with biomass pellet standards from Indonesia, Japan, Korea, and Germany. Results indicate that bark affects several properties, with higher ash content observed in pellets with bark due to the higher mineral content in bark. Volatile matter decreases with finer particle size, influencing combustion rate. Moisture content is higher in pellets with bark, impacting combustion efficiency and smoke production. Fixed carbon values are influenced by moisture and volatile matter content. Calorific values are generally higher in pellets without bark and smaller particle sizes. Density and compressive strength increase with decreasing particle size. FTIR analysis reveals differences in functional groups between pellets with and without bark, indicating variations in chemical composition. Overall, this research provides insight into the potential of calliandra biomass pellets with bark and without bark along with particle size as a renewable energy source.

Abstract

Reptiles are cold-blooded animals that need to be known and their evenness as an environmental bio-indicator. The purpose of the study was to determine the diversity of species and the diversity of reptiles. The research was conducted in December 2020-January 2021 at the Integrated Field Laboratory of the University of Lampung. The research data was collected using the Visual Encounter Survey (VES) method with a combination of the Time Search method. Then the results were analyzed quantitatively using the Shannon-Wiener diversity index and the type mapping index. The results showed that there were five types of reptiles observed, namely the wall lizard (Hemidactylus frenatus), garden lizard (Eutropis multifasciata), striped blackhead snake (Hemalopsis buccata), grass lizard (Takydromus sexlineatus) and welang snake (Bungarus candidus) in the medium category. This is because the habitat still has sufficient food availability, whereas since human activities the habitat has been slightly disturbed. In the third habitat, the distribution of reptiles is even and the distribution of reptile species is included in the category of stable community. The reptile species found were not different because the distance in the three habitats was not too far away which made it easier for the species to move around. The balance of the campus environment can be determined by monitoring and researching the existence of reptiles at the University of Lampung. In addition, other efforts to reduce hunting and illegal trade in reptiles provide protected status for reptile species.

Abstract

Damar resin harvesting tools play an important role in the preservation of local community traditions and culture, economy and environmental sustainability. The purpose of the study was to examine the tools in the harvesting of damar resin in Pahmungan Village, Pesisir Barat Regency, Lampung Province. A qualitative approach is an option in this research. In-depth interviews, participant observation and documentation study were conducted for data collection, then examined to explain the production tools used by the community in damar resin harvesting. The results of the study show that harvesting activities start from the selection of trees to harvest. Harvesting is carried out at regular intervals, about 20 to 30 days, to ensure the resin produced is optimal and of high quality. Good harvesting techniques are carried out so that the quality of resin and the survival of resin trees are maintained. Resin harvesting is carried out using traditional tools. The tools used are axe, basket, ambon, and bebalang. Its use is part of a cross-generational culture that needs to be preserved for its sustainability. The use of resin harvesting tools is part of the community's culture, because it reflects its identity and knowledge. This is the result of interaction with their agroforestry land. Some of the tools have been changed, due to difficulties in obtaining raw materials and practical reasons; for example: the use of plastic buckets that replace basket made of rattan.

Abstract

Vibriosis caused by Vibrio, such as V. parahaemolyticus, is one of several issues in shrimp farming. Antibiotic misuse in disease controlling is suspected of producing environmental contamination resistance of micorbia, and rejecting the products. One of the efforts that can be made to overcome vibriosis by utilizing endophytic fungi in mangroves. This is due to the similarity of bioactive compounds produced by mangroves and endophytic microorganisms. The aim of this research was to analyze at the bioprospection of endophytic fungi as anti-V. parahaemolyticus at the Lampung Mangrove Center (LMC). The aim of this study was to analyze at the bioprospection of endophytic fungi as anti-V. parahaemolyticus at the Lampung Mangrove Center. The method used in the study was exploratory by isolating endophytic fungi from the roots and leaves of mangrove plants that predominantly grow in LMC for further biaoctivity screening process against V. parahaemolyticus. This study employs an exploratory approach with descriptive analysis. Based on the antibacterial activity test using the agar plug method, 9 out of 76 fungal isolates showed the ability to inhibit the growth of V. parahaemolyticus, namely isolates coded L-A1-MD1, L-A1-MD2, L-A1-MD3, L-A2-MA4, L-A2-MA5, L-A2-MA6, L-B1-MD18, L-P4-MA47, and L-A6-MA79. All isolates of endophytic fungi that had bactericidal activity against V. parahameolyticus predominantly come from the mangrove plant Avicena marina.

Abstract

The distribution of subsidized fuel for fishermen is largely determined by government regulations and policies. A well-implemented distribution institution ensures that subsidized fuel reaches fishermen appropriately. This study aims to analyze the institutionalization of subsidized fuel for fishermen in Kangkung Village, Bumi Waras District, Bandar Lampung City. The approach used is a qualitative approach with a case study method. Data collection through in-depth interviews, participatory observation and documentation studies. Data processing is carried out to analyze the institutionalization of subsidized fuel distribution for fishermen. The results of the study indicate that fishermen who use diesel fuel obtain subsidized diesel fuel at fishermen's fuel station according to the provisions set by the Downstream Regulatory Agency Committee Oil and Fuel. Not all fishermen can meet the required provisions. This causes there are still fishermen who cannot access subsidized diesel fuel for their business needs. Fishermen who use Pertalite also cannot freely access subsidized pertalite at the fuel station due to less supportive institutional governance. Thus, it is still necessary for the government to improve regulations so that distribution is more effective and controlled, so that subsidized fuel can be accessed evenly by small fishermen.

Abstract

The low sustainability of participation in the Fishermen’s Insurance Premium Assistance program shows that there is an Institution issue. The research intents to analyze the institution of the fishermen’s insurance program in Bandar Lampung City. This study used the case study method as a qualitative approach. Data were obtained by in-depth interviews, participant observation, and document analysis. Analysis is used to describe institutions based on situation, structure, behavior, and performance. The results of the study show that the efforts of the insurance program in Bandar Lampung City to protect fishermen have not been achieved in the second year. This occurred because the insurance participants did not pay the premium independently or at personal expense. The fishermen are not interested in participating in insurance, in spite of the premium cost being economical. Institutions are included in the BPAN program, which plays an important role in determining the continuation of fishermen’s insurance participation. The government should consider the punishment and agreements that must be submissive by fishermen to become effective regulation. In addition, the Social Security Administrator for Employment, as an insurance provider, must accommodate the simple insurance premium payments for fishermen.

Abstract

The sustainability of forest functions is closely related to the perspective of the communities living around it. This study aims to analyze community perspectives on forest conditions in KTH Talang Ponijan and Sidodadi I. Data was collected using a qualitative approach through in-depth interviews, participant observation, and documentation studies. The collected data were analyzed descriptively and qualitatively. The results of the research show that there are still differences between the community's views and their behavior towards community forest management (HKm). Most people in KTH Talang Ponijan and Sidodadi I utilize HKm land to improve their welfare. However, conditions in the field reveal that illegal practices such as logging, poaching, opening up new land for cultivation, and unsustainable land management threaten the balance of nature and worsen forest conditions. The government is expected to provide environmental education programs and facilitate training or guidance to strengthen the community's capacity to manage and utilize forests wisely.

Abstract

Industri penggergajian kayu di Indonesia memainkan peran penting dalam pemanfaatan sumber daya hutan dan mendukung perekonomian lokal. Penelitian ini bertujuan untuk mengidentifikasi sifat kayu gergajian yang digunakan dalam industri sawmill di Kabupaten Pesawaran, khususnya di Kecamatan Way Ratai dan Kecamatan Gedong Tataan. Data dikumpulkan melalui observasi langsung, wawancara dengan pemilik industri, serta studi literatur. Hasil penelitian menunjukkan bahwa industri sawmill di wilayah ini memanfaatkan berbagai jenis kayu dari hutan rakyat, termasuk bayur (Pterospermum javanicum), durian (Durio zibethinus), jati (Tectona grandis), mahoni (Swietenia macrophylla), dan jabon (Neolamarckia cadamba). Identifikasi kayu yang diamati meliputi sifat fisis, mekanis, dan kimia. Secara fisis, kayu memiliki variasi dalam berat jenis, kadar air, dan arah serat yang memengaruhi stabilitas dan ketahanannya. Dari aspek mekanis, kayu diklasifikasikan berdasarkan kelas kuatnya, dari kelas I (sangat kuat) hingga kelas V (kurang kuat). Hasil penelitian menunjukkan bahwa kayu dengan kelas kuat antara tertinggi yaitu kayu jati yang tergolong dalam kelas II sedangkan kayu sengon, waru dan jabon tergolong kelas kuat rendah yaitu III- IV sehingga hal tersebut yang menentukan penggunaannya dalam konstruksi dan industri mebel. Sifat kimia kayu memiliki kandungan selulosa dan lignin, juga berpengaruh terhadap daya tahan kayu terhadap serangan organisme perusak, sehingga penelitian ini dapat menjadi acuan bagi industri pengolahan kayu dalam memilih bahan baku yang sesuai dengan kebutuhan produksi dan mempertimbangkan aspek keberlanjutan dalam pengelolaan hutan rakyat.
