Since 2016 the government has accelerated the registration of land systematically complete until in 2025 the whole plot of land in Indonesia registered. In 2018 alone the government is targeting 7 million fields, and 2019 is targeting 9 million. To achieve these targets is required technology that can overcome this. Drone, better known as Unmanned Aerial Vehicle (UAV) or unmanned aircraft technology as a solution for mapping of land with a large target, time and area flexibility desired shooting, and detailed shooting spatial resolution results as well as a relatively cheaper cost than the recording price with satellite. This research uses qualitative method. Data were obtained from the study literature. After the data collected it will be done data analysis with three stages, namely; Reduction, Display, and Conclution. The results of this study shows that the use of drones for the acceleration of land mapping is the right choice because the drone shots have spatial resolution which is so high that it complies with ground mapping rules and the price is cheap.

<p>Soal merupakan salah satu instrumen yang digunakan untuk mengukur keberhasilan dalam mencapai tujuan pembelajaran. Soal yang akan dijadikan sebagai alat evaluasi harus memenuhi ciri-ciri soal/tes yang baik diantaranya adalah soal tersebut harus valid. Salah satu cara untuk mengetaui valid atau tidaknya soal yang digunakan perlu diadakan analisis terhadap soal tersebut, salah satunya dengan analisis validitas isi soal terkait. Selama ini di beberapa sekolah atau madrasah, khususnya di MA NU TBS Kudus dalam pembuatan soal Penilaian Tengah Semester (PTS) ataupun Penilain Akhir Semester (PAS) khususnya Matematika, belum pernah dianalisis isi soalnya terkait dengan kesesuaian antara tiap butir soal dengan silabus yang ada pada kurikulum 13 saat ini atau dengan kata lain analisis validitas isi terhadap butir-butir soal tersebut. Mengingat urgensi dari soal sebagai alat untuk mengukur keberhasilan pembelajaran, sangat penting untuk diadakan penelitian tentang analisis butir soal. Penelitian ini bertujuan untuk mengetahui validitas isi dari butir soal PTS Mata Pelajaran Matematika Wajib XI MA NU TBS Kudus Tahun Pelajaran 2018/2019 sebagai upaya untuk meningkatkan kualitas proses pembelajaran berbasis nilai-nilai islam. Penelitian ini menggunakan metode deskriptif kualitatif dikarenakan penelitian ini tidak menggunakan data dalam bentuk angka dan akan mendeskripsikan validitas isi dari soal Penilaian Tengah Semester Gasal mata pelajaran Matematika wajib kelas XI MA NU TBS Kudus tahun pelajaran 2018/2019.Berdasarkan hasil analisis rasional validitas isi yang membandingkan antara soal dengan silabus /kurikulum disimpulkan bahwa validitas isi satu paket soal yang dibuat oleh guru mapel Matematika Wajib kelas XI sudah terpenuhi. Namun dalam penulisan soal masih perlu ketelitian, karena masih ada soal yang tidak ada jawaban dipilihan yang ditawarkan, yaitu soal no.4, disamping itu juga perlu kecermatan dalam menuliskan simbol-simbol, arsiran yang terdapat dalam soal PTS, yaitu nomor 11, 20, 22 dan 25, dan kesesuaian bahasa atau kalimat yang digunakan dalam soal tersebut kurang baik, yaitu pada nomor 7, 8, 14, 21, 22, 23 dan 25.</p>
Abstract. Eddy S, Dahlianah I, Mashito C, Oktavia M, Utomo B. 2022. Anthropogenic implications for land cover changes and vegetation structure in coastal protected forest. Biodiversitas 23: 4473-4481. Anthropogenic activities in coastal areas have largely eliminated mangrove forest cover, including the Air Telang Protected Forest (ATPF). This study aims to analyze land cover changes in 2021 and the vegetation structure in ATPF which covers an area of ??approximately 12,660.87 ha. The method used in this study is a survey method with two stages of data collection, namely the collection of image data and vegetation data. Image data for 2021 was obtained from Landsat 8 Oli, while vegetation data were collected through the identification of plant species and quantitative analysis through the calculation of the Important Value Index (IVI) and the Shannon Diversity Index (H?). The results of this study show that there has been deforestation in ATPF by 66.4% until 2021 due to land conversion into coconut plantations, oil palm plantations and open areas. The number of plant species obtained was 20 species consisting of seven true mangrove species and 13 associated mangrove species. The diversity index ranges from 0.00 to 0.62 which is included in the low category.
Abstract. Sidabukke SH, Barus TA, Utomo B, Delvian. 2021. The undergrowth composition and distribution in different forest area utilization. Biodiversitas 22: 5255-5261. Forests provide natural raw materials to support various human activities and also demonstrate a wide range of biodiversity, both in terms of wildlife and plants. Based on biological resources, undergrowth species form a significant portion of the forest ecosystems and have overgrown the typical wooden plants. These ground cover/undergrowth groups are known to exhibit diverse complexities and a type of basic vegetation existing under the forest stands. Therefore, the purpose of this study is to determine the composition and distribution of undergrowth species in each forest area designation, including industrial, protected and natural forests. The plot technique was employed, with an area of 2 m x 2 m. This involves a total of 480, 224 and 96 plots in the industrial plantations, protected and natural forest areas, respectively. Also, the entire plants in the measuring plot were recorded, starting from the sprouts up to 1.5 m high. Subsequently, the important value index (IVI) and Morisita index methods were applied in the data analysis. The results showed the occurrence of 98, 57 and 33 undergrowth species in industrial, protected as well as in natural forests, correspondingly. Based on the important value index calculations, Sintrong species (Crassocephalum crepidioides) reported the maximum IVI (31.587%) in industrial forest plantations, alongside Senduduk (Melastoma malabathricum) and Paku Wangi (Phymatosorus scolependria) in the protected areas (29.951%) and natural forests (29.551%), respectively. Furthermore, the Morisita index indicated that the undergrowth distribution pattern for the three areas was clustered, uniform and random, but with varying percentages. However, only two distribution patterns, including random and clustered were peculiar to the natural forests.
Abstract. Sahputra E, Harahap RH, Wahyuningsih H, Utomo B. 2021. Assessing the sustainability status of mangrove forest ecosystem management by coastal community in Jaring Halus Village, North Sumatra, Indonesia. Biodiversitas 22: 1-9. Mangrove forest ecosystems provide various important ecological (physical and protection) and economic services. Mangrove forest needs to be sustainably managed to ensure their functions and benefits are available in perpetuity. Still, issues regarding sustainable management of mangrove forests are rarely discussed, especially in Indonesia. This research aims: (i) to gain the fundamental understanding of the level of sustainable mangrove management by determining indicator attributes that can be categorized as leverage factors; ii) obtain the perceptions of coastal communities in mangrove forest management; and iii) investigate the compliance of coastal communities in mangrove forest management. Data were obtained through a series of interviews, field observation and focused group discussion (FGD) and questionnaires conducted from January 2018 to March 2019 in Jaring Halus Village, Secanggang Subdistrict, Langkat District, North Sumatra, Indonesia. Data were analyzed using multidimensional scaling (MDS). The results showed that the status of mangrove forest management in Jaring Halus Village was categorized as moderately sustainable with a score of 65.83%. The majority of the coastal community (96% of respondents) perceived and understood the value of protecting the mangrove ecosystem, which provided physical (ecological), economic, and social functions. The community's understanding and knowledge of the importance of mangrove forests is due to the high level of dependency on their main livelihood as fishermen. Around 97% of the respondents held strong obedience to the mangrove forest management in Jaring Halus Village, which could be attributed to local wisdom related to natural resource management.
Potency of peat in Indonesia is high as media of plant and also organic fertilizer, but the height of soil acidity caused decomposition prosesed running lag so that this contents of soil nutrient element also low. This research was aimed to detect activator influences in increasing growth of Gmelina arborea plants in peat soil and also calculate peat soil chemical property changes as result of bioactivators application. The peat soil materials came from countryside of
This research explored the application of Islamic educational management for 7th graders at SMPN 1 Wonosegoro. The case study used interview, observation, and documentation to collect data which later were analyzed qualitatively. This school was chosen as the research setting because despite being a non-Islamic institution where religious and moral cultures were not commonly incorporated in the curriculum and school activities, it had several exceptional religious programs. It is found that their Islamic educational management is concerned to three major sub-areas namely; student orientation, curriculum, and extracurricular activities. These programs have been reviewed to have given significant impacts on their moral, social, and religious values proven with the very low number of student delinquency and a very good record of prayer habits among students.
