Abstract

The research aims to observe the influence of harvesting time on the change of calcium oxalate (CaOx) content and crystal density in Porang corms. The corms were harvested at different times, i.e., (1) two weeks before the plants shed (R0-1), (2) when the plants shed (R0), and (3) two weeks after the plants shed (R0+1). CaOx was obtained using the modified extracting method. Microscopic observations were obtained from the slices of the edge and center part of porang corms. Parameter observed including CaOx content, corm weight, shape, and density of CaOx crystal. CaOx content and crystal density in corms were analyzed using One way ANOVA. If the results are significant, it will be followed by Tukey Test α 0.05. In the meantime, the relation between CaOx content and corm weight was analyzed using Correlation Test Bivariate. The results showed that CaOx content was relatively higher in porang corms, i.e., 15.98 ± 0.60g/100g. On the other hand, the increasing of CaOx content might improve corm weight. The total density of druse, styloid, and prism crystal was pretty high in corms obtained when the plants shed compared to another harvest time, i.e., 1,494 ± 286; 31,280 ± 17,406 and 6,256 ± 1,533 crystals/cm2 . Raphide crystal density, by contrast, increased in corms obtained after the plants shed, i.e.,1,656 ± 368 crystals/cm2 . Total CaOx crystal density in the edge parts of corms harvested when the plants shed was proportionately higher than in the other harvest times, i.e., 12,292 ± 4,687.89 crystals/cm2 . In contrast, CaOx crystal densities in the center parts of corms were not much different at three harvesting times. The density of druse and prism crystals was somewhat higher in the center part of corms than in the edge parts. In opposition to, the density of raphide and styloid crystals was fairly higher in the edge part of corms than it was in the center parts. However, only raphide crystal density found in the edge and center part of corms was significantly affected by harvest time from all these results.

Abstract

Chemical compounds are presumed to interact with each other and potentially affect the crystal development of porang tubers. This study focused on glucomannan and calcium oxalate (CaOx) as chemical compounds found in porang. Crystal development was analyzed by microscopic observation. The tuber tissue was used for microscopic slides and was harvested two weeks before the plants lost their leaves, when the plants lost their leaves, and two weeks after the plants lost their leaves. The CaOx and glucomannan content was measured using a modified extraction method. The increasing of CaOx content tends to increase the number of CaOx crystals. The analysis showed that the crystal density could affect the increasing of tuber weight possibility. There was a development process in raphide crystals that showed by different sizes at three harvest times, which the others were not. The results also indicated that glucomannan might influence the crystal density and the CaOx content. It can be concluded that glucomannan can potentially induce CaOx synthesis and crystal count increase. Keywords: Caox, Crystal, Development, Glucomannan, Interact, Porang.

Abstract

Penelitian ini bertujuan untuk mengevaluasi efektivitas penambahan bawang putih, serai, dan daun sirsak dalam formulasi pestisida nabati berbahan dasar daun pepaya terhadap penurunan jumlah hama dan kerusakan daun pada tanaman kangkung cabut (Ipomoea reptans Poir). Penelitian ini menggunakan metode eksperimen lapangan dengan Rancangan Acak Kelompok (RAK) yang terdiri atas lima taraf perlakuan dan lima ulangan, sehingga terdapat 25 satuan percobaan. Perlakuan terdiri dari P0 (kontrol); P1 (daun pepaya); P2 (daun pepaya + bawang putih), P3 (daun pepaya + serai), dan P4 (daun pepaya + daun sirsak). Pestisida nabati diformulasikan melalui proses penghalusan bahan aktif dalam 300 mL air, diikuti inkubasi selama tiga hari, penyaringan, dan pengenceran hingga 1 liter. Penanaman kangkung cabut dilakukan pada bedengan berukuran 1 × 1 meter dengan perlakuan budidaya standar, meliputi penyiraman, penyiangan, dan pemupukan dasar. Pestisida nabati diaplikasikan dengan metode penyemprotan sebanyak dua kali, yaitu pada minggu ketiga dan keempat setelah tanam, pada sore hari. Parameter yang diamati meliputi persentase penurunan jumlah hama serta kerusakan daun. Data yang diperoleh dianalisis secara deskriptif untuk menggambarkan pengaruh aplikasi pestisida nabati terhadap populasi hama dan tingkat kerusakan tanaman kangkung. Perlakuan paling optimal diperoleh dari kombinasi daun pepaya dan serai (P3), yang mampu menurunkan jumlah hama hingga 87,5% dan dapat menekan kerusakan daun dibandingkan perlakuan lainnya. Masih ditemukan tanda-tanda serangan berupa bercak cokelat dan bekas gigitan pada beberapa perlakuan, yang menunjukkan bahwa efektivitas pestisida nabati turut dipengaruhi oleh stabilitas senyawa aktif yang digunakan. This study aimed to evaluate the effectiveness of adding garlic, lemongrass, and soursop leaves to a plant-based pesticide formulation using papaya leaves as the main ingredient in reducing pest populations and leaf damage in upland water spinach (Ipomoea reptans Poir). The research was conducted through a field experiment using a Randomized Complete Block Design (RCBD) consisting of five treatments and five replications, resulting in 25 experimental units. The treatments included P0 (control), P1 (papaya leaves), P2 (papaya leaves + garlic), P3 (papaya leaves + lemongrass), and P4 (papaya leaves + soursop leaves). The botanical pesticide was formulated by blending the active ingredients with 300 mL of water, followed by incubation for three days, filtration, and dilution to a final volume of 1 liter. Upland water spinach was cultivated on plots measuring 1 × 1 meters using standard cultivation practices, including watering, weeding, and base fertilization. The pesticide was applied twice by spraying, in the third and fourth weeks after planting, during the late afternoon. Observed parameters included the percentage reduction in pest numbers and leaf damage. The most effective treatment was P3 (papaya leaves + lemongrass), which reduced pest populations by 87.5% and significantly suppressed leaf damage compared to other treatments. However, signs of pest activity such as brown spots and bite marks were still observed in some treatments, indicating that the effectiveness of the botanical pesticide was also influenced by the stability of the active compounds used.

Abstract

Household waste management has become a significant challenge in maintaining environmental cleanliness and improving community welfare. This community service program aims to implement waste processing based on the 3R principles (Reduce, Reuse, Recycle) with added economic value in the Community Self-Help Group (KSM) Paguntaka, Tarakan City. The activities include education, training, and mentoring in managing organic waste. Organic waste is processed into compost using a simple fermentation method.. The program's results indicate an increase in community understanding of the 3R concept and the ability to process waste into economically valuable products. Furthermore, additional income from the sale of recycled products has contributed to improving the welfare of KSM members. This program also positively impacts reducing the volume of waste that ends up in the landfill, thus supporting environmental conservation efforts. In conclusion, the 3R-based waste management approach involving community empowerment has proven effective in generating economic and environmental benefits. This program is expected to be replicated in other communities to support sustainable waste management.

Abstract

Kimchi is an agricultural product made form fermented vegetables. Kimchi can be made with various types of vegetables such as Chinese cabbage, green mustard greens, cabbage, cucumber, radish and various other vegetables. Currently, kimchi is not only popular in Korea but also in other countries, including Indonesia. It is because kimchi contained high health benefits so that increasingly popular among Indonesian people. Fermentation gives kimchi its unique taste and texture. Tasted of kimchi dominated by acid which is lactic acid from fermentation by Lactic Acid Bacteria (LAB). Produced lactic acid can lower the pH and increase the sour taste. The lactic acid fermentation process will be perfect if the factors that influence the growth of lactic acid bacteria can be properly  controlled. Factors that influence lactic acid bacteria growth are fermentation temperature, salt levels and the presence of nutrients. Determining the quality of kimchi is based on taste, nutritional value and food safety. Determination of organoleptic values was carried out by untrained respondents. Determination of nutritional value is carried out by chemical content analysis in the laboratory. The fermentation process is strongly influenced by the environment and growth substrate. Therefore, sometimes kimchi that made with the same ingredients can produce different tastes and qualities. In determining the right quality of kimchi, various tests are needed based on existing standards. These standards cover physical, chemical and organoleptic properties. From research it is known that the type of salt has an influence on water content values (25, 390), vitamin C levels (12,725), and lactic acid (28, 21246). The use of fine salt causes the water content and vitamin C values to be low. A higher salt concentration causes the salt, vitamin C and lactic acid levels to be higher as well. Meanwhile, based on organoleptic tests, the kimchi in the K4G1 treatment was the kimchi most liked by the panelists

Abstract

Selama masa pertumbuhan tanaman membutuhkan nutrisi. Penambahan pupuk anorganik urea sebagai unsur hara nitrogen seringkali tidak efektif karena siffat urae yang cepat tersedia sehingga potensi hilang sangat besar baik melalui penguapan maupun pelindian. Teknologi pupuk lepas lambat menjadi alternatif untuk menjamin ketesediaan hara N, efisiensi serapan hara N bagi tanaman, serta kesuburan sifat tanah. Efektivitas pupuk lepas lambat dapat dipengaruhi oleh faktor bahan pendukung. Potensi jenis bahan pendukung pembungkus urea yang berasal dari bahan organik sangat besar, seperti arang sekam, arang tempurung kelapa dan limbah udang. Penelitian ini bertujuan mengkaji pengaruh bahan pembungkus formula pupuk lepas lambat Urea-Organik terhadap perubahan sifat kimia tanah dan ketersediaan hara Nitrogen. Penelitian dilaksanakan adalah percobaan inkubasi yang dilakukan dalam laboratorium (Insitu) dengan perlakuan : Kontrol (tanpa perlakuan), F1 (Urea), F2 (Urea-arang sekam), F3 (Urea-arang tempurung kelapa), F4 (Urea-limbah udang). Parameter yang diamati yaitu pH tanah, kandungan C-Organik dan N-Nitrat tanah dari sampel tanah yang diambil pada 0, 14, 28, 42, dan 56 hari setelah inkubasi perlakuan. Hasil penelitian menunjukkan bahwa penggunaan arang sekam, arang tempurung kelapa, dan limbah udang sebagai bahan pembungkus urea dalam formula pupuk lepas lambat mampu meningkatkan ketersediaan hara nitrogen (N-Nitrat), serta mampu memperbaiki pH tanah dan kandungan bahan organik tanah dari sebelum perlakuan. Dalam hal uji korelasi antara pH, kandungan C-organik dan kandungan N-Nitrat menunjukkan korelasi yang tidak signifikan. Oleh karena itu perlu ada penelitian pembanding yang dilaksanakan di lapangan dengan beragam faktor yang mempengaruhi.

Abstract

This paper describes about the role of taxonomic in ecotourism development in Indonesia. Development and management of ecotourism in Indonesia recently are still quite slow and inadequate. It is due to the lack of knowledge of local community about the information of flora and fauna which is used as ecotourism attraction. Therefore the taxonomical science needs to be applied to the development of ecotourism in Indonesia. In addition, some species which are used as tourist attractions needs to be identified and classified to preserve the resource. Implementation of taxonomy related to survey, documentation, data collection, identification and classification to establish the identity of a species for ecotourism attraction. Methods are commonly used for the implementation of taxonomy in the ecotourism development, i.e. (1) morphological observation, (2) vocalizations and (3) molecular analysis. Morphological observations can be applied by qualitative and quantitative observations. Qualitative observation is an observation of a species, which is related to morphology and coloration, and comparison with other species which are suspected related. Quantitative observation is a morphometric analysis, which is a concept of quantitative analysis of the species that related to the size and shape of a species. Vocalization method is applied by determining the vocal character of a species, by comparing the data, which has obtained, with the data vocals from other species which are suspected related. Molecular analysis is commonly used to support the identification of morphological and vocalization of the species. Molecular methods, which are commonly applied for species identification, are usually hybridization, DNA sequencing, restriction mapping, chromosome banding and immunological method Keywords: taxonomy, ecotourism, Indonesia, morphological observation, vocalization, molecular identification

Abstract

Sukamade Coastal Area located in Meru Betiri National Park has particular object as ecotourism attraction, i.e. Sea Turtle. On the other hand, national park management use the cross subsidy from ecotourism activities to promote the conservation action plans for the survival of sea turtle. This study was aimed to formulate action plans to develop the sea turtle conservation as ecotourism attraction in Sukamade Coastal Area. Field observation was conducted to evaluate the current activities of the sea turtle conservation and ecotourism activities in Sukamade. Semi-structured interview and secondary data collection was also conducted to support the formulation of the action plan. Data was analyzed by SWOT method to be developed into action plan. Results showed that the management of sea turtle conservation and ecotourism activities in Sukamade Coastal Area has been attempted to meet the conservation concept for sea turtle but also beneficial for the ecotourism implementation. However, we recommend a long term and short term action plan for the sustainability of the sea turtle conservation and ecotourism activities in Sukamade Coastal area. It includes the mangrove restoration, sea turtle feed development, mapping of sea turtle distribution and migration, the use of up to date biotechnology, workshop on conservation management, and the development of research facility in the area. Additional to the current policy on sea turtle conservation and ecotourism activities, the action plan that we recommended were expected to improve the sustainability management in Sukamade Coastal Area. Keywords: Action Plan, conservation, ecotourism, Sea Turtle.
