The diazotroph bacteria as ecofriendly biofertilizers play an important role in improving the N status and availability of paddy soil. Laboratory experiment to study nitrogenase activity and IAA production of diazotroph from rice rhizosphere and to assess its effect on the growth of rice seedling has been conducted from September to October 2014 in Agronomy and Horticulture Laboratory Faculty of Agriculture Jenderal Soedirman University, Purwokerto. The experiment was arranged as a completely randomized design and consisted of seven treatments and provided with 4 replications. The treatments were the isolates of indegenous diazotroph (T1 = A11003, T2 = A230041, T3 = A24001, T4 = A230022, T5 = A230021, T6 = A230042 and T7 = without inoculation). The nitrogenase activity measured by acetylene reduction assay method and IAA production was measured by HPLC method. Plant height, leaf greeness, leaf area, total dry weight and total root length were determined on 21 days after sowing. The experimental results showed that the isolat A230021 was identified as Rhizobium sp. LM-5 and have the highest nitrogenase activity at 0.07 µM C2H4 ml -1 h -1 and IAA production reached 19.01 ppm. Inoculation with strains of diazotroph enhanced chlorophyl content, total root length, and biomass production.

Tengger tribe is one of the tribes in Indonesia that live around Bromo Tengger Semeru National Park (BTSNP) area. BTSNP area inhabited by the Tengger tribe people is an area in Indonesia with high biodiversity. The local wisdom of the Tengger tribe is in terms of the use of natural resources for various requirements of their lives. This study aimed to explore the utilization of multiple plants by the Tengger tribe in Ngadas and Ranupani villages around BTSNP. This research used surveys and group discussion (GDF) methods involving traditional leaders and some people of the Tengger tribe. The data obtained were analyzed descriptively and qualitatively. The results showed that the plants used for traditional medicinal materials were 25 species, food sources were 17 species, industrial materials and household were 11 species, building materials were 17 species, ecological functions were nine species, and traditional ritual ceremonies were seven species. The Tengger tribe used the natural resources in the form cultivation plants and non-cultivation plants to support in all aspects of their livelihood.

Restoration through re-vegetation activities is one of the solutions to recover degraded peatlands quickly. Shorea balangeran is one of the most promising species of Dipterocarpaceae that can be chosen for the degraded peatlands rehabilitation. The bagworm is one of the potential pests to damage the S. balangeran in Ogan Komering Ilir (OKI) regency. The objective of the study was to provide various information about bagworm insect pests on S. balangeran. Two measuring plots of 50 x 32 m laid on 2017 planted S. balangeran in agrosilvofishery based on integrated peat restoration pilot project. The variables observed were the number of attacked plants to calculate incidence and the number of attacked leaves in each observation unit (tree) using a scoring system to calculate the intensity. The data obtained were analyzed by descriptive quantitatively. The results showed that there were two species of bagworm in S. balangeran. The incidence of both bagworms was quite high, but the intensity of damage was still relatively mild. However, control measures for bagworms still need to be carried out.

Ethnopharmaceutical research-based booklets are teaching material that contains important information that is presented in a concise and interesting manner for the general public to study. This research aims to develop a booklet for ethnopharmaceutical research-based communities in the Bromo Tengger Semeru National Park area. This research method uses the development adopted from the ADDIE learning model. Data is collected through identification of plants in the field and group discussion forums with the Tengger community. While the booklet's eligibility data was validated by media experts and content material experts, as well as the effectiveness of the booklet being tested on community groups. The results of this study indicate that there are about 40 types of medicinal plants commonly used by the Tengger community. The results of media and content material validation obtained 88.95% and 80% results, which are included in the very valid and quite valid criteria and can be used. The results of the booklet trial on the community group including readability and practicality tests obtained 86.42% and 91.65% which were included in the criteria that were read well and were very practical. Booklet development from the results of research can be a learning media that is more easily understood in learning biology related to plant diversity and utilization.

Kesesuaian kompetensi lulusan Sekolah Menengah Kejuruan  dengan kebutuhan di industri mutlak diperlukan. Program SMK Pusat Keunggulan (SMK PK) yaitu program yang mendorong adanya keselarasan dan menyeluruh antara sekolah dengan industri. Program SMK PK meliputi bidang kurikulum, pembelajaran, peningkatan jumlah dan peran instruktur dari industri, praktik industri, sertifikasi kompetensi, update teknologi, Riset terapan, dan serapan lulusan oleh dunia kerja. Program SMK PK tersebut di atas, tentu menjadi tantangan baru baik bagi sekolah maupun guru. Tujuan pengabdian pada masyarakat ini adalah untuk mengidentifikasi tantangan yang dihadapi sekolah dan guru dalam Program SMK PK. Hal ini penting untuk dilakukan karena melalui kegiatan identifikasi ini maka kegiatan pengabdian  masyarakat yang dilakukan akan sesuai kebutuhan. Metode yang digunakan adalah wawancara secara mendalam untuk memperoleh informasi secara komprehensip tantangan yang dihadapi oleh sekolah dan guru. Hasil yang diperoleh bahwa  sekolah masih menghadapi kesulitan dalam menjalin hubungan dengan industri sehingga berdampak pada pengembangan kurikulum, pelaksanaan pembelajaran, kehadiran instruktur dari industri, dan magang kerja. Sementara masalah yang dihadapi oleh guru adalah pemahaman tentang kurikulum  operasional, terbatasnya informasi dan pelatihan  banyaknya istilah baru yang digunakan dalam kurikulum. Oleh karena itu fasilitasi bermitra dengan industri dan pelatihan pemahaman guru terhadap kurikulum perlu dilakukan.

The aims of this research was to study the net assimilation rate, growth and yield of rice with the application of PGPR in different rate of nitrogen fertilizer. The experimental was conducted in experimental farm of Agriculture Faculty of UNSOED Purwokerto. The research was arranged in Randomized Block Design with three replications. The first factor is PGPR consortium, and the second factor is dosage of nitrogen fertilizer. The observed variables were plant height, number of tillers, plant biomass, leaf greenness, plant biomass, net assimilation rate, relative growth rate and yield. Data were analyzed using ANOVA followed with DMRT test for mean comparison between group. The results showed that PGPR consortium inoculation and nitrogen fertilization have effect on root growth, leaf greenness, and plant biomass. The PGPR consortium R08 isolate + R11 isolate and nitrogen fertilizer at dose of 1.36 g plant−1 gave highest net assimilation rate of 5.87 g dm−2 week−1. The highest grain yield was achieved at nitrogen fertilizer dose of 2.72 g plant−1 at 36.17 g per hill.
