Agricultural activity relies on soil as their growth media. Besides agricultural activity, other living species also needs soil as their ecosystem. However, the biodiversity and environmental factor are often neglected in agricultural activity. Therefore, the investigation of environmental and biodiversity changes is important. In this study, the environmental parameter and biodiversity changes was investigated in area after land clearing activity. The pH was increased from in 3 times measurement. Besides, the soil temperature and air temperature was also increased in 3 times measurement between pre- and post-treatment. The soil temperature ranges from 26.2 oC to 33.2 oC in pre-treatment and 27.6 oC to 31.8 oC in post-treatment. The air temperature was observed ranges from 27.96 oC to 34.3 oC in pre-treatment and 28.36 oC to 34.56 oC in post-treatment. Measurement of RH was resulted ranges from 61.2% to 75.4% in pre-treatment and 61.4% to 74.8% in pre-treatment. The land is proposed become paddy field for next step land processing. As result, the diversity index was decreased in pre- and post-treatment. The Shannon diversity index was decreased from 0.81 to 0.72. Similarly, the Simpson diversity index was also decreased from 1.94 to 1.77. Meanwhile, the evenness index was increased from 0.58 to 0.65. These results suggested for farmer to process the land as soon as possible after land clearing process, if they want to form paddy field from pasture land.AbstrakKegiatan pertanian bergantung pada tanah sebagai media tumbuh suatu tanaman. Selain kegiatan pertanian, organisme hidup lain juga bergantung terhadap tanah sebagai ekosistem. Namun, seringkali biodiversitas dan faktor lingkungan diabaikan dalam kegiatan pertanian. Oleh karenanya, indentifikasi perubahan lingkungan dan biodiversitas sanget perlu dilakukan. Dalam penelitian ini, perubahan parameter lingkungan dan biodiversitas diamati sebelum dan sesudah aktivitas land clearing. Hasil pengamatan menunjukkan, pH tanah, suhu tanah dan suhu lingkungan meningkat dalam 3 kali pengukuran dari sebelum ke sesudah aktivitas land clearing. Suhu tanah berkisar 26.2 oC-33.2 oC pada sebelum kegiatan land clearing dan 27.6 oC-31.8 oC setelah aktivitas land clearing. Suhu lingkungan ditemukan berkisar 27.96 oC-34.3 oC pada kegiatan sebelum land clearing dan 28.36 oC-34.56 oC setelah kegiatan land clearing. Hasil pengukuran RH lingkungan ditemukan berkisar 61.2%-75.4% pada kegiatan sebelum land clearing dan 61.4%-74.8% setelah kegiatan land clearing. Sementara itu, index diversitas ditemukan menurun setelah aktivitas land clearing. Nilai Shannon diversity index ditemukan menurun setelah aktivitas land clearing dari 0.81-0.72. Pola serupa ditemukan pada nilai Simpson diversity index, dimana terjadi penurunan dari 1.94 menjadi 1.77. Nilai evenness index meningkat dari 0.58 menjadi 0.65. Berdasarkan hasil tersebut dapat disarankan ke petani untuk segera mengolah lahan tersebut setelah kegiatan land clearing untuk menghindari terjadinya pertumbuhan kembali vegetasi, serta perubahan parameter lingkungan dan biodiversitas.

Drip irrigation and self-watering are two examples of irrigation technology improvements that employ effective and efficient watering methods. Water productivity may be used as a benchmark to compare irrigation efficiency and agricultural productivity. The purpose of this study was to assess mustard green's water productivity under conventional, drip, and self-watering irrigation systems. The effect of irrigation variation on mustard green growth was studied using a nonfactorial technique with a completely randomized design (CRD). The design has three treatments and six replications. This study examined the following variables: height, number of leaves, yield, irrigation water utilized, and water productivity of mustard green. The study found that mustard green plants require 0.69 mm/day of water in the vegetative phase, 2.83 mm/day in the generative phase, and 1.69 mm/day in the final phase. The use of different watering systems has a significant influence on mustard green's height and leaf number. Self-watering at 15 g/L provides the maximum water productivity for mustard green, followed by drip irrigation at 8.46 g/L and conventional irrigation at 7.69 g/L. Keywords: Drip irrigation, Mustard green, Self-watering irrigation, Water productivity

Drip irrigation technique, in combination with the utilization of organic matter like as biochar and cocopeat, can increase water productivity by tailoring irrigation water to plant demands. This study was to investigate how organic matter can improve water productivity in mustard green production utilizing a drip irrigation technique. The greenhouse pot experiment analyzes the effect of adding varying quantities of biochar and cocopeat to mustard greens' growth medium using a drip irrigation technique. The findings indicate that adding organic matter reduced the quantity of water needed for irrigation. The soil and biochar combination treatment at a 1:1 ratio resulted in the highest water productivity for mustard green, whereas the control treatment produced the least. Mustard green grows optimally in a soil + biochar (1:1) growing medium, yielding the most water productivity at 16.8 g/L. Biochar can boost biomass yield by twice as much as the control treatment. Furthermore, biochar can increase mustard green water productivity by more than 300% when compared to mustard green, which relies solely on soil for planting medium. Further study is needed to investigate the effects of biochar features on water holding capacity, field capacity, and wilting point in different soil types to improve irrigation efficiency. Keywords: Drip irrigation, Irrigation efficiency, Organic matters, Water productivity.

Perkembangan teknologi robotika dari waktu ke waktu sangat mengagumkan. Produk teknologi robotika tersedia semakin banyak dan bervariasi mulai dari robot yang paling sederhana sampai dengan yang paling canggih sehingga robot dapat sesuai untuk memenuhi berbagai kebutuhan manusia. Melihat dari besarnya dampak teknologi robotika di masa mendatang, maka sangat diperlukan pengenalan teknologi ini kepada para siswa sekolah agar dapat menjadi inventor di bidang teknologi robotika agar Indonesia mampu menghasilkan teknologi yang bersaing dengan negara-negara maju. Pengenalan teknologi robot di sekolah dapat dilakukan dengan metode pembelajaran STEAM (Science, Technology, Engineering, Arts, and Mathematics) yang menggabungkan lima bidang ilmu yaitu sains, teknologi, teknik, seni dan matematika. Metode ini dapat mendorong siswa untuk lebih berperan aktif, berpikir kritis, berkomunikasi, dan bekerja sama dalam menyelesaikan suatu permasalahan. SMPN (Sekolah Menengah Pertama Negeri) 3 Natar belum memiliki materi pelajaran atau media pembelajaran ataupun ekstrakurikuler yang terkait dengan bidang ilmu robotika. Hal ini dikarenakan masih kurangnya pemahaman dan pengetahuan insan akademis yang terkait dengan bidang teknologi robotika tersebut.

The use of energy, especially fossil fuels in the world, is increasing along with the increasing human population and increasing industrial development in various countries that use conventional energy. The way to reduce the use of conventional energy is to use renewable energy, one example of renewable energy is biobriquettes. Biobriquettes are solid fuels derived from the remaining organic matter that has undergone a compression process with a certain compressive force. The purpose of this study is to analyze the characteristics and determine the optimum parameters of biobriquettes from rubber seed shell charcoal and bagasse with variations in adhesives (tapioca flour, sago flour and molasses). The ratio of charcoal to adhesive mixture is 90:10, 85:15, 80:20. The stages of research on making biobriquettes include raw material preparation, carbonization, printing and product analysis. The results of the study showed that there were 2 characteristic parameters that met the standard values in all adhesive variations, namely moisture content and ash content, except for molasses adhesive variations with a ratio of 80:20 and the optimum parameters obtained in biobriquettes mixed with rubber seed shell charcoal and taboo pulp using tapioca adhesive with a ratio of 90:10 with a moisture content value of 4.53%, ash content 4.78%, flying substance content 31.33%, carbon content 59.36%, calorific value 4422 cal/g, combustion rate 0.097 g/min, and drop test 30.9%.
