Abstract

Bamboos are one of the plant species that make up forest vegetation that has many benefits both economically, ecologically and socio-culturally. Environmental quality can be assessed using data on the diversity of bamboo species. This study aims to determine the composition and level of diversity of bamboo species in the Bukit Kinai region. Determination of sampling locations using purposive sampling method with double plots. This research was conducted in January-April 2023 in the Bukit Kinai area of Setanduk Village, Capkala District, Bengkayang Regency. Seven bamboo species from four different genera were identified, namely Bambusa vulgaris Schrad Ex. JC Wendl, Dendrocalamus asper (Schult. F) Backer, Gigantochloa hasskarliana (Kurz) Backer, Schizostachyum blumei Nees, S. brachyladum (Kurz ex Munro) Kurz, S. lima (Blanco) Merrill, and S. mampouw Widjaja. The highest Frequency, Density and INP values were found in the species Gigantochloa hasskarliana (Kurz) Backer, which were 0.85, 261.25 clumps/ha, and 110%, respectively. Low species richness (R = 1.059), low species diversity (H = 0.917), and moderate species evenness and species dominance (E = 0.471 and C = 0.555) were observed in the Bukit Kinai region. Based on this study, the bamboo community in the Bukit Kinai area was in an unstable condition so that its environmental quality can be categorized as poor.

Abstract

Crystal guava is an agricultural fruit for the community in Rasau Jaya Village, Kubu Raya, West Kalimantan. Crystal guava is marketed in the form of fresh fruit with a relatively high and stable price. However, when the fruit harvest is abundant, guavas that are not immediately processed/consumed are easily rotten, causing farmers to lose money. Making fruit chips is a post-harvest processing effort that can increase selling value and overcome fruit damage. The purpose of this activity was to educate fruit farmers in Rasau Jaya through making crystal guava chips for post-harvest fruit management and increasing selling value to overcome losses. Partners in this activity were fruit farmers in Rasau Jaya. The method in this activity was training (theory delivery, demonstration and practice). Education participants were satisfied with the activity of making crystal guava chips (90%) and gained additional knowledge and skills (95%). Participants hope that after participating in this activity they can process crystal guava into chips so as to increase income and minimise losses due to guava damage.

Abstract

Makroalga merupakan salah satu potensi sumberdaya laut yang secara ekologis berperan dalam meningkatkan produktivitas primer perairan, bioremediasi berbagai jenis polutan, penyedia oksigen, sumber makanan, dan menyediakan habitat berbagai jenis biota akuatik lainnya. Secara ekonomi, makroalga juga potensial untuk dikembangkan karena mengandung berbagai senyawa bioaktif yang dapat dimanfaatkan di berbagai bidang industri. Keanekaragaman jenis dan kelimpahan makroalga sangat dipengaruhi oleh parameter fisika-kimia perairan. Desa Temajuk, Kecamatan Paloh memiliki keanekaragaman sumberdaya alam, termasuk makroalga. Lokasi pengambilan sampel sebanyak tiga stasiun dan ditentukan menggunakan metode purposive sampling, berdasarkan keberadaan makroalga. Sampling makroalga dilakukan menggunakan kuadrat transek dengan ukuran 10x10 m2 dan pengukuran parameter fisika-kimia perairan menggunakan WQC AZ 8603. Hasil penelitian menunjukkan bahwa jenis makroalga yang ditemukan yaitu Padina, Turbinaria, Sargassum, Acanthopora, dan Gracilaria. Dari semua jenis yang teridentifikasi, Phaeophyceae memiliki persen kontribusi lebih besar (60%), serta Padina dan Sargassum memiliki kelimpahan tertinggi, yaitu 21,31 ind/mek 2 dan 19,42 ind/m2 secara berturut-turut. Perairan Desa Temajuk memiliki tingkat keanekaragaman sedang, keseragaman tinggi, dan dominansi rendah. Kondisi perairan mempengaruhi kelimpahan makroalga di perairan Desa Temajuk, Kecamatan Paloh.   Macroalgae is one of the potential marine resources that ecologically plays a crucial role in increasing the water’s primary productivity, bioremediation of various types of pollutants, as food sources, providing oxygen and habitat for various aquatic biota. Economically, macroalgae also potential to be developed because it contains various bioactive compounds that can be used in various industrial fields. Species diversity and abundance of macroalgae are strongly influenced by physio-chemical water parameters. Temajuk Village located in Paloh District has a high diversity of natural resources, including macroalgae. The sampling locations were three stations and determined using purposive sampling method, based on the presence of macroalgae. A sampling of macroalgae was carried out using a quadratic transect with a size of 10x10 m2 and measurement of the physio-chemical parameters was done using WQC AZ 8603 instrument. The results showed that the genera of macroalgae found were Padina, Turbinaria, Sargassum, Acanthopora, and Gracilaria. Among the identified species, Phaeophyceae had the highest percentage contribution (60%), which Padina and Sargassum had the highest abundances, such as 21.31 ind/m2 and 19.42 ind/m2, respectively. The waters of Temajuk have a moderate level of diversity, high uniformity, and low dominance. Water conditions influenced the diversity and abundance of macroalgae in the water of Temajuk, Paloh District.

Abstract

Dairy cow's milk is a primary commodity in various countries and increasing milk production in dairy cows is crucial. Clitoria ternatea has the potential to enhance milk production in dairy cows. This research aims to analyze C. ternatea's ability to induce milk production in dairy cows by targeting the DRD2 protein. The compounds within C. ternatea were screened for drug-likeness, toxicity, physicochemical properties, and membrane permeability parameters. The DRD2 protein in dairy cattle was modeled using homology modeling. The interaction stability between C. ternatea compounds and DRD2 was analyzed through molecular docking and dynamic using AutoDock Vina and Webgro. The study results revealed that among the 18 compounds, 5 passed the drug-likeness screening: citronellal, alpha-terpinolene, 15-methyxypaysine, allyl-crotyl-zinc, and 9,12-octadecadiynoic. These 5 compounds exhibited low toxicity and demonstrated easy penetration of lipid membranes. Molecular docking results indicated that citronellal and alpha-terpinolene had the lowest binding energy values and were bound to the inhibitor's side. Molecular dynamic simulations also confirmed the stability of the interaction between citronellal and alpha-terpinolene with DRD2. In conclusion, this research suggests that C. ternatea can potentially increase milk production in dairy cows by inhibiting the DRD2 protein, primarily through citronellal and alpha-terpinolene.

Abstract

This study aims to determine the morphology of seed embryos, sprout development, and germination components. The research design was RAL based on priming materials and soaking time. Each treatment consisted of four replicates. Data were analysed descriptively qualitatively and quantitatively. Expired mustard seeds have fewer viable embryos than unexpired seeds. The sprout development of expired mustard seeds was slower than unexpired seeds. The fastest average germination time was in seeds soaked in 0.3% KNO3 solution for 8 hours and distilled water for 2 hours (2.53 and 2.52 days), the highest average germination percentage was in seeds soaked in 0.3% KNO3 solution for 6 hours and distilled water for 2 hours (82.5%), average hypocotyl length of the longest sprouts in seeds soaked in 0.3% KNO3 solution and 2 hours distilled water (1.62 and 1.68 cm), and average radicle length of the longest sprouts in seeds soaked in 0.3% KNO3 solution 2 hours and 10 hours distilled water (1.33 and 1.28 cm).
