Abstract

Mangrove forests have a very diverse microbial population. Among these microbes, some have the ability to convert mangrove forest organic waste into useful nutrients for the sustainability of the mangrove ecosystem. One of the species that has this ability is the marine yeast Rhodotorula sp. Apart from this ecological role, the yeast Rhodotorula sp. reported to have a lot of biotechnology potential, including as a producer of lipid omega-3, carotenoids, anti-bacterial, plant growth promoter, anti-cancer, biosurfactant, and a very potential workhorse for biotechnology applications. As a country that has the largest mangrove forest in the world, Indonesia has not reported much and has not intensified the use of marine yeast Rhodotorula sp. from Indonesian mangrove forests as a bioresource for high-value strategic products. This study aims to isolate the marine yeast Rhodotorula sp. from the mangrove forest of Pari island, Jakarta and reviewing the ecological role and biotechnological potential of these species. Marine yeast Rhodotorula sp. obtained will be cultivated and exploited its biotechnology potential in the future

Abstract

Penerapan metode jarimatika di Pusat Pemulihan Dalam Komuniti (PPDK) Changlun dirancang untuk membantu anak-anak berkebutuhan khusus dengan pendekatan inovatif dan interaktif, menggunakan gambar animasi jari-jari tangan dan video digital sebagai visual. Metode ini bertujuan untuk memberikan pengalaman belajar yang menyenangkan dan efektif dengan mengintegrasikan teknik pengenalan angka melalui jari tangan dan teknologi digital. Namun, terdapat kendala berupa variasi tingkat kemampuan dan kebutuhan anak yang memerlukan penyesuaian metode secara berkelanjutan. Dukungan dari staf PPDK dan keterlibatan aktif pendidik dalam pelatihan sangat penting, bersama dengan fasilitas yang memadai dan antusiasme anak-anak terhadap kegiatan belajar. Evaluasi berkelanjutan, termasuk umpan balik dari pendidik dan anak-anak, dilakukan untuk menilai pencapaian tujuan pendidikan dan memperbaiki kualitas pembelajaran.

Abstract

Caisim (Brassica juncea L.) is a widely consumed leafy vegetable that requires adequate nutrients for optimal growth. This study aimed to investigate the effect of rabbit manure on the growth of caisim plants, specifically focusing on fresh weight, dry weight, and root length. The experiment was conducted using a Completely Randomized Design (CRD) with five treatments and five replications. Treatments consisted of different soil-to-rabbit manure ratios: P0 (control, no manure), P1 (1:1), P2 (2:1), P3 (3:1), and P4 (4:1). The results showed that the application of rabbit manure significantly affected all three observed growth parameters. The best results were obtained in the P2 treatment (2:1 ratio), which yielded an average fresh weight of 21.902 g, a dry weight of 1.17 g, and a root length of 5.58 cm. These findings suggest that rabbit manure supplies essential nutrients, including nitrogen, phosphorus, and potassium, which contribute to enhanced root development and overall plant growth. The 2:1 ratio was found to offer the most effective nutrient balance for caisim cultivation. The implication of this study is that rabbit manure can serve as an environmentally friendly and effective organic fertilizer alternative to chemical fertilizers, supporting sustainable agricultural practices and offering a practical solution for enhancing the productivity of horticultural crops.

Abstract

Chicken is the most consumed food commodity in Indonesia. Chicken also contains protein which is needed by the body to maintain body strength. However, due to the Covid-19 pandemic, chicken prices have soared due to the increasingly expensive feed prices along with the increase in demand for chicken in the market. This study aims to determine the effectiveness of feeding Maggot Hermetia illucens and Microalgae Aurantiocyhtrium sp. as a source of protein and fatty acids in Joper chickens (Gallus domesticus). Using a completely randomized design (CRD) consisting of 6 treatments and 4 repetitions. Treatment P0 (100% Bran, Corn, Pur feed), P1 (Maggot 30%, microalgae Aurantiochytrium sp. 1.5%, Bran, Corn, Pur 68.5%), P2 (Maggot 35% and microalgae Aurantiochytrium sp. 2%, Bran, Maize, Pur 63%), P3 (Maggot 40% and microalgae Aurantiochytrium sp. 2.5%, Bran, Maize, Pur 57.5%), P4 (Maggot 45% and microalgae Aurantiochytrium sp. 3%, Bran, Maize, Pur 52%), P5 (Maggot 50% and microalgae Aurantiochytrium sp. 3.5%). Parameters observed were final body weight and daily weight gain rate of joper chickens. The results of this study showed that the provision of P5 treatment gave the best results in increasing protein and omega-3 levels with results of 18.19% and 4.53% respectively compared to the protein and omega-3 content of the control treatment which only amounted to 16.62% and 1.17% respectively. This study provides results with treatment P5 which has a major effect on the growth of joper chicken (Gallus domesticus). The results of this study can be an option for chicken feed because it is proven to increase protein and omega-3 content in chickens.

Abstract

Sampah yang dihasilkan di pulau Pari jauh lebih tinggi saat musim liburan. Sampah organik dari sisa sayur dan makanan laut menimbulkan aroma tidak sedap. Sampah anorganik dari plastik dan sterofoam terlihat di pinggir pantai. Sampah tersebut harus bisa dikurangi dari bagian hulu yaitu rumah warga. Pulau Pari yang dikelilingi oleh laut mengharuskan warganya untuk mengelola sampah dengan bijak agar tidak berakhir di laut. Dengan demikian, warga memerlukan sistem manajemen pengelolaan sampah dapur sebagai solusi yang tepat untuk menanggulangi sampah dari bagian hulu. Dapur warga dijadikan sebagai tempat mengolah makanan katering oleh ibu rumah tangga sebagai pelaku usaha tersebut. Para ibu yang tentunya memiliki waktu luang di rumah perlu diberdayakan potensinya untuk melakukan manajemen sampah dari dapur rumahnya. Kegiatan pelatihan manajemen sampah dapur meliputi identifikasi sampah di rumah dan pemilihan penanganan sampah. Pengabdian ini difokuskan pada pembentukan pola pikir warga tentang pentingnya peran ibu rumah tangga dalam pengurangan dan penanganan sampah di daerah hulu yakni tidak lain di dapur rumahnya sendiri. Para ibu sangat antusias dengan kegiatan pemilahan serta pengolahan kulit udang menjadi bumbu masakan dan cangkang telur menjadi pupuk tanaman.

Abstract

The COVID-19 pandemic made higher education institutes support online education. Searching for the learning difficulties of students who have gone through lectures online needs to be done as anticipation and looking for solutions in the next lecture. This quantitative descriptive research was conducted in biology education study programs that have studied Plant Physiology in the 2020-2021 academic years. 56 respondents were given a questionnaire related to their difficulties during the online lectures. Learning difficulties in the external aspect were the slow internet network (58.90%) and the internal aspect was very difficult to focus on listening to online lectures if the room where the lecture was messy (58.90%). Physical and physical health profile, easy to get sore and sleepy during the course (57.10%). On the profile of academic learning, students find it more difficult to find textbooks during online lectures than during offline lectures (69.60%). The characteristics of the courses that affected the mastery of the material were the presence of many illustrations of physiological processes (30.40%) and complex concepts (30.40%). Lecturers and students work together to overcome these difficulties so as not to disrupt the overall course of lectures so that online lectures continue well.
