Abstract

Lebah merupakan hewan dari kelas Insecta yang menghasilkan produk kaya manfaat, diantaranya madu, propolis, dan bee pollen. Lebah, khususnya yang tanpa sengat, dapat dibudidayakan oleh masyarakat perkotaan karena relatif aman. Tim Pengabdian Masyarakat Multidisiplin Universitas Indonesia, yang terdiri dari Fakultas Matematika dan Ilmu Pengetahuan Alam, Fakultas Teknik, dan Fakultas Ilmu Administrasi bekerjasama dengan komunitas “3bee” telah melaksanakan serial workshop secara daring dengan topik pemanfaatan lebah. Selain itu, tim pengabdi dengan “holistika institute” juga mengajak masyarakat untuk memanfaatkan sampah rumah tangga agar dapat diolah kembali menjadi produk yang dapat menghidupkan perekonomian rumah tangga. Serial workshop terdiri dari empat seri, masing-masing terdiri dari dua sesi. Topik yang disampaikan meliputi pengenalan lebah dan urban bee; tanaman pakan lebah dan produk lebah; pangan sehat dari lebah; pengolahan sampah organik dan anorganik; serta pemasaran dan kualitas pelayanan. Workshop diselenggarakan selama 4 Pekan mulai tanggal 10 Oktober hingga 7 November 2020. Selain pemaparan narasumber, terdapat pre-test, post-test, dan evaluasi kegiatan dari peserta pada tiap seri. Peserta workshop berjumlah 171 orang yang berasal dari berbagai wilayah di Indonesia. Sebagian besar berasal dari kalangan akademisi, komunitas penggiat lebah, serta pegawai dinas lingkungan dan kehutanan. Berdasarkan hasil evaluasi, sebagian besar peserta merasa sangat puas (rentang kepuasan 4,21-5,00) dengan workshop yang terselenggara dan berencana mengimplementasikan pengetahuan yang diperoleh dari workshop ini (87%). Program pengabdian masyarakat multidisiplin ini dapat diduplikasi pada program lain sehingga penyampaian materi bersifat komprehensif. Program ini diharapkan dapat terus dikembangkan melalui program pendampingan sehingga lebah dan sampah dapat dimanfaatkan untuk meningkatkan ekonomi rumah tangga berkelanjutan di Indonesia.

Abstract

The study aims to observe coconut shell liquid smoke as a bio-fungicide in controlling F. oxysporum growth. The treatment was applied on sample i.e., coconut shield liquid smoke as a bio-fungicide, compared with a chemical fungicide as a positive control, and without treatment as a negative control. The direct observation was conducted for four weeks, with treatment application every seven days. The analysis of variance test shows the difference of three treatments in controlling the F. oxysporum growth for each observation period. Still, it has no difference in average in fungal growth after treatment. According to the results of weekly observations, coconut shell liquid smoke biofungicide reduces the disease severity on the tapping fields infected by F. oxysporum in the range of 13-21%, whereas chemical fungicide reduces the disease severity in the range of 1-10%. In conclusion, the ability of coconut shell liquid smoke bio-fungicide to control is relatively shorter compared to chemical fungicide. Based on the inhibition ability of coconut shield liquid smoke, it is recommended that utilize various grades of coconut shell liquid smoke as a comparison.

Abstract

Air pollution is a global issue that has a harmful impact on living things and the environment. It is commonly recognized that bioremediation, including the use of tree plants, helps reduce air pollution. Tree plants can respond physically to air pollution. The value of the air pollution tolerance index (APTI) can be used to determine the physiological response. Based on APTI values, this study seeks to determine the tolerance levels and physiological response differences of six tree plant species (Mangifera indica, Pterocarpus indicus, Cerbera odollam, Pometia pinnata, Syzygium myrtifolium, and Swietenia macrophylla) in Pulogadung Industrial Estate, East Jakarta and Universitas Indonesia (UI) Campus, Depok. Environmental factors and APTI values with relative water content parameters, leaf extract pH, ascorbic acid content, and total chlorophyll content were measured in six kinds of tree plants at both research sites. The maximum APTI score in the Pulogadung Industrial Estate was 9.79 0.13, indicating that Mangifera indica plants are air pollution tolerant. Meanwhile, Pterocarpus indicus is classified as sensitive to air pollution, with the lowest APTI score of 6.59 0.18 at the UI Campus, Depok. The APTI test results revealed that tolerant species had high relative water content (RWC) values and ascorbic acid concentration, whereas sensitive species had low RWC values and poor total chlorophyll content.

Abstract

The main challenge for urban food security is a public policy perspective that considers food security only from a rural lens and agricultural activities in the cities are appraised to have no place. In dealing with that challenge, the local government of Depok City has developed a local urban food system program called Pekarangan Pangan Lestari (P2L) in Bojongsari Sub-district. The existence of P2L influenced the increase of Depok City's food security score by 1.68 within 5 years and placed Depok City as the 10th city with the highest food security index in Indonesia. This study aims to document the characteristics and utilization of P2L in the Bojongsari Sub-district. The research was conducted using in- depth interviews with 30 people and field observation in 33 P2L. The area of Pekarangan Pangan Lestari (P2L) in the Bojongsari Sub-district can be found in the villages of Duren Seribu, Duren Mekar, Pondok Petir, and Serua, is categorized as moderate and narrow, and managed by the Women Farmers group. P2L functions as living barns (lumbung hidup), living stalls (warung hidup), living pharmacies (apotek hidup), nurseries, livestock, and fisheries. A total of 92 species belonging to 86 genera and 47 families were identified in Bojongsari Sub-district. These plants have been used by the society in Bojongsari Sub-district as a source of medicine, vegetables, spices, herbs, vitamins, and carbohydrates as much as 55%, 17%, 10, 9, 8,17, respectively. Besides, there are several animals raised in P2L such as chickens, goats, and catfish.

Abstract

Background: Air pollution is a threat to the environment. Sources of air pollutants in urban environments can be in the form of dust, heavy metals, and hydrocarbons. Plants can help clean air pollutants from the atmosphere by absorption through the stomata, accumulating them, or by adsorption on the leaf surface. The Air Pollution Tolerance Index (APTI) is used as an evaluation benchmark for the Physiological conditions of plants exposed to air pollution. This research aims to study the physiological conditions of six tree species in air conditions in the Depok City area and to assess the plants' tolerance level based on the APTI calculation. Methods: The physiological parameters measured to calculate APTI were ascorbic acid, total chlorophyll, leaf extract pH, and Relative Water Content (RWC). The six tree species used as objects in this study were Artocarpus altilis, Artocarpus heterophyllus, Bauhinia purpurea, Ficus septica, Filicium decipiens, and Nephelium lappaceum. Results: Differences in the physiological conditions of six tree species in the Depok City area based on the average ascorbic acid values, total chlorophyll, leaf extract pH, and RWC. In addition, there are also differences in APTI parameters between the two research locations. Conclusions: Filicium decipiens is the plant species with the highest APTI, while Artocarpus heterophyllus has the lowest. Based on the APTI scores, Bauhinia purpurea, Ficus septica, Filicium decipiens, Nephelium lappaceum belong to moderately tolerant category, Artocarpus altilis belongs to an intermediate category, Artocarpus heterophyllus belongs to sensitive category.

Abstract

Fungal diseases pose a substantial risk to the health and productivity of rubber plants (Hevea brasiliensis (Willd. ex ​ A. Juss.) Mull. Arg., the primary source of natural rubber. The diverse fungal pathogens responsible for these diseases lead to significant economic losses in rubber plantations, threatening the global rubber supply. This review provides a comprehensive examination of major fungal diseases affecting rubber plants, focusing on their identification, scientific analysis, and management strategies. Conventional methods for pathogen identification, while valuable, often lack the efficiency and precision required for effective disease control. Recent advancements in molecular diagnostics, genomics, and biotechnology have greatly improved the accuracy and speed of pathogen detection, enabling more targeted and sustainable management practices. Integrated pest management, mainly through the use of disease-tolerant clones, is emerging as a viable alternative to chemical fungicides. Although chemical fungicides remain the most widely used solution due to their accessibility and effectiveness, their environmental impact and potential for resistance necessitate a shift toward sustainable practices. While biofungicides offer a more environmentally friendly option and are already in use, they are currently limited to small-scale plantations and have yet to be adopted for large-scale production. Efforts to develop resistant clones through molecular studies and advanced cloning techniques are ongoing, representing the most sustainable approach for combating fungal diseases in rubber plantations. By synthesizing current knowledge and advancements, this review underscores the pressing challenges in managing fungal diseases and the opportunities presented by innovative technologies. The findings aim to guide future research and promote the development of efficient, sustainable strategies for maintaining rubber crop health, ensuring consistent production, and safeguarding the economic stability of the rubber industry.
