Study of Biogas Production with Organic Rubbish as Producing Material

This research had done at Production and Agricultural Machines and Equipments Management Laboratory at Agricultural Engineering, Faculty of Agricultural Technology, Andalas University, Padang City from November 2011 to March 2012. It intent to study about biogas physics parameters (to know about when the first time it producing biogas, biogas volume and pressure, relative humidity (RH), enviroment temperature, biogas energy) and chemical parameter such as producing material acidity degree (pH) in the beginning and last obsevation. It obsevation method has two different ways. First, using combination of 35 kgs radish and 35 cabbages rubbish as producing material. Second ways is using 70 kgs radish rubbish. Each way mixed by 4 liters EM4 as decomposer, 70 liters water, and observed for 30 days. The result showed in first way that biogas had produced first time at 9th day with 554,4 kJ biogas energy,  productivity is 0.47 liter biogas / kg producing material, 28.6 oC enviroment temperature, 80.1 % RH, 456.1 Pa biogas pressure, 6.1 starting pH, and 6.6 last pH. In second way had obtained that in 9th day is first time biogas had produced with 537.6 kJ energy, productivity is 0.42 liter biogas / kg producing material, 28.2 oC environment temperature, 82.1 % RH, 436.2 Pa biogas pressure, 6.3 starting pH, and 6.8 last pH.   

Hubungan perilaku hidup bersih dan sehat dengan pengetahuan kebersihan gigi dan mulut di SDN 1 karang maritim Bandar Lampung

Background: One of the problems in Indonesia that needs attention is the problem of dental and oral health. Improper clean and healthy living behavior in school-age children can cause various diseases, one of which is dental and oral hygiene problems. One of the triggering factors that are thought to be related to dental and oral hygiene is lack of knowledge. Purpose: The purpose of this study was to determine the relationship between clean and healthy living with knowledge of dental and oral hygiene in school-age children. Methods: This type of research is a type of quantitative research using a descriptive correlation research design using a cross sectional approach. The population in this study were 3rd grade students of Elementary School 1 Karang Maritim. The sample in this study were members of the population taken by simple random sampling with a total of 27 respondents. Results: Based on the results of research conducted on August 12, 2022 regarding the relationship between Clean and Healthy Lifestyle Behavior with knowledge of brushing teeth in grade 3 students of Elementary School 1 Karang Maritim, Bandar Lampung City, the results of the study of respondents with knowledge of brushing their teeth with poor knowledge were 1 students (3.7 percent), with good knowledge as many as 26 students (96.3 percent). Conclusion: It can be concluded that there is a relationship between clean and healthy living behavior with knowledge and dental and oral hygiene with a p-value of 0.000 <0.05.   Pendahuluan: Salah satu masalah di Indonesia yang perlu diperhatikan adalah masalah tentang kesehatan gigi dan mulut. Perilaku hidup bersih dan sehat yang tidak baik pada anak usia sekolah dapat menyebabkan timbulnya berbagai penyakit salah satunya yaitu permasalahan kebersihan gigi dan mulut. Salah satu faktor pemicu yang diduga berhubungan dengan kebersihan gigi dan mulut yaitu kurangnya pengetahuan. Tujuan: Tujuan penelitian ini adalah untuk mengetahui hubungan hidup bersih dan sehat dengan pengetahuan kebersihan gigi dan mulut pada anak usia sekolah. Metode: Jenis penelitian ini merupakan jenis penelitian kuantitatif dengan menggunakan rancangan penelitian deskriptif kolerasi menggunakan pendekatan cross sectional. Populasi dalam penelitian ini adalah siswa kelas 3 SDN 1 Karang Maritim. Sampel dalam penelitian ini adalah anggota populasi yang diambil secara simple random sampling dengan jumlah 27 responden. Hasil: Berdasarkan hasil penelitian yang dilaksanakan pada tanggal 12 Agustus 2022 tentang hubungan Perilaku Hidup Bersih dan Sehat dengan pengetahuan menggosok gigi pada siswa kelas 3 SDN 1 Karang Maritim Kota Bandar Lampung diperoleh hasil penelitian responden dengan pengetahuan menggosok gigi dengan pengetahuan buruk sebanyak 1 siswa (3,7 persen), dengan pengetahuan baik sebanyak 26 siswa (96,3 persen). Simpulan: Dapat disimpulkan bahwa adanya hubungan antara perilaku hidup bersih dan sehat dengan pengetahuan dan kebersihan gigi dan mulut dengan nilai dilihat p-value 0,000 < 0,05

FISHERIES SANCTUARY PLANNING IN PRACTICE: LESSON LEARNT FROM ECOSYSTEM APPROACH TO FISHERIES MANAGEMENT IN NORTH KALIMANTAN PROVINCE

Governor Decree of North Kalimantan No. 26 in 2014 concerning Management of Bombay Duck in the North Kalimantan Province Waters was established in order to address over-exploitation of bombay duck (Harpadon nehereus) population. Fisheries sanctuary is the feasible solution that was agreed by comprehensive stakeholder discussion. This research aims to extract and elaborate our experiences on establishing fisheries sanctuary in the Bangkudulis waters which focus on science communication and in the fisheries sanctuary planning. The acoustic and larva survey conducted to support the consensus and to proof the traditional ecological knowledge of the communities. The results showed that the proposed conservation area of the Bangkudulis waters has significant ecological function to ensure the sustainability of bombay duck population. The distribution and abundance of larva and juveniles were found higher in that area. The approach and challenges to deal with ecological and socio-economic aspects as well as recommendations were discussed in this paper

Proceedings of the 3rd International Conference on Community Engagement and Education for Sustainable Development

This proceeding contains articles on the various ideas of the academic community presented at The 3rd International Conference on Community Engagement and Education for Sustainable Development (ICCEESD 2022) organized by the Universitas Gadjah Mada, Indonesia on 7th-8th December 2022.  ICCEESD is a biannual forum for sharing, benchmarking, and discussing HEI’s activities in developing Education for Sustainable Development towards community engagement. Education for Sustainability as a teaching strategy for resolving community challenges through formal, informal, or non-formal education is expected to benefit from various community service best practices by academics, researchers, and students. The 3rd ICCEESD has “Strengthening Education for Sustainability Towards Better Community Engagement” as its theme this year. It is expected that the 3rd ICCEESD will provide a forum for the presenters and participants to exchange best practices, policies, and conceptual implementation of Education for Sustainability towards better community engagement and explore ideas to address community needs.  Conference Title: 3rd International Conference on Community Engagement and Education for Sustainable DevelopmentConference Theme: Strengthening Education for Sustainability Towards Better Community EngagementConference Acronyms: ICCEESD 2022Conference Date: 7th-8th December 2022Conference Location: Grand Rohan Jogja Yogyakarta, IndonesiaConference Organizer: Universitas Gadjah Mada, Indonesi
