Biomass is a potential source of energy developed as an alternative source of substitute for fossil fuels and can be renewed. One of the fuels derived from biomass is corncob biobriquette waste. Thisstudy aims to determine the characteristics of physical properties (heat value and density) chemical properties (water content, ash content, levels of flying matter, and carbon content) and endurance (stability and strength). This research method was experimental, namely direct observation through the carbonization process and quantitative data measurement. The adhesive used is starch and aquadest with a ratio of 1: 4, to measure the heating value of briquettes using a bomb calorymeter. From the research results of briquettes A, B, and C, it can be seen that the physical properties, chemical properties and durability produced are apparently not much different compared to coal briquettes. The highest heating value produced by coal briquettes is around 6.058,62 cal/g while the heating value in composition A biobriquette is 5.956,21 cal/g, composition B is 5.241,78 cal/g and the lowest heating value is found in composition C biobriquette namely 4,935.91cal/g. The results showed that biobriquette from corn cobs and rubber latex with compositions A and B were still in accordance with SNI.

Adoption is the acceptance of an innovation in farming that is influenced by many factors. This research discussed the level of farmer adoption and the factors that influence farmers in the use of living supports on pepper plants. The research was conducted in Pemali District, Bangka Regency from March to May 2021. Data collection methods were observation and interview methods using questionnaires that had been tested for validity and reliability, with data analysis methods using likert scale and multiple regression tests. The result showed the level of farmer adoption level on the use of living supports on pepper plants is high with a percentage 75,25%, for regression analysis it has a regression equation that is Y= - 0,573 0,129X1 + 0,124X2 + 0,623X3 + 0,203X4. Further test using t-count shows that the characteristics of innovation factor has a very significant influence and access to information media factor has a significant influence with the t-count value greater than t-table.

Vetiver root is a commodity that is tolerant enough to be planted in salty soils with a certain level of salinity. One approach to increase oxidative stress tolerance that will increase the enzyme substrate at the cellular level is ascorbic acid. The purpose of this study was to increase students' knowledge about how the response of vetiver seed (Vetiveria zizanioides) growth in salt soils to ascorbic acid through practical field learning in plant physiology courses. This research was conducted using a factorial randomized block design (RBD), the first factor was the salinity (S), namely S0: 0 dsm-1 and S1: 4 dsm-1. The second factor was ascorbic acid (A), namely A0: without treatment, A1: 50 ppm, A2: 100 ppm and A3: 150 ppm. There were 8 treatment combinations that were repeated 3 times resulting in 24 experimental units. The parameters observed were plant height, number of leaves and number of stomata. In this study, ascorbic acid had a significant effect on plant height, number of leaves and number of stomata. Saline soil had a significant effect on the number of stomata parameters. No interactions for all parameters were observed.

Deficiency or excess magnesium in the soil can affect the vegetative and generative growth of plants. This study aimed to identify the effect of magnesium deficiency and toxicity on the agronomic and physiological characteristics of upland rice. The study was conducted on farmers' land, Medan Selayang Subdistrict, Medan City, from June 2021 to January 2022. This study used a non-factorial randomized block design, namely the application of 27% MgO fertilizer based on the deficiency rates, (0; 1/2; 1/4; 1/8; 1/16; 1/32 times), while the toxicity levels include 0; 2; 4; 8; 16; 32-times within three replicates. The results showed that Mg deficiency significantly inhibited the growth of plant height; leaf area; total chlorophyll SPAD; panicle length; shoot dry weight; and yield.ha-1 were 20.68; 26.77; 19.23; 22.60; 44.20; and 50.72%, respectively. The Mg toxicity significantly inhibited the growth of the leaf area, the number of tillers, number of productive tillers, shoot dry weight, and root dry weight were 14.24; 32.15; 42.87; 34.07; and 44.31%, respectively. The critical limit (BK50) for upland rice caused by deficiency and toxicity of Mg were 0.032 and 1125.189 g/10 kg of the soil, respectively.

Teknik perbanyakan kopi secara vegetatif dengan cara setek memiliki beberapa keunggulan yaitu menghasilkan tanaman baru dalam jumlah banyak dengan waktu relatif singkat dan biaya operasional yang relatif murah. Namun kelemahan dari teknik perbanyakan ini adalah tingkat keberhasilannya yang lebih rendah dibandingkan teknik lain. Penelitian ini bertujuan untuk mengkaji pengaruh interaksi antara perbedaan konsentrasi Zat Pengatur Tumbuh (ZPT) air kelapa dan ekstrak bawang merah terhadap respon pertumbuhan setek kopi robusta yang berasal dari pucuk (S1) dan ruas pertama setelah pucuk (S2). Penelitian ini dilakukan di laboratorium lapangan perkebunan Politeknik Pembangunan Pertanian Medan menggunakan rancangan acak kelompok pola faktorial. Faktor pertama adalah pucuk pertama dan ruas pertama setelah pucuk, faktor kedua adalah konsentrasi ZPT 50% dan 75% serta kombinasi ZPT air kelapa dan ekstrak bawang merah dengan 5 ulangan. Variabel yang diamati meliputi jumlah tunas, jumlah daun, diameter daun, panjang akar dan jumlah akar. Data yang diperoleh dianalisis dengan ANOVA (Analysis of variance) dan dilanjutkan dengan uji Duncan taraf 5%. Hasil penelitian menunjukkan pemberian konsentrasi ZPT bawang merah 50%. dapat meningkatkan jumlah tunas, jumlah daun, diameter daun, panjang akar dan jumlah akar. Pemberian konsentrasi ZPT bawang merah 50%. y juga memberikan pengaruh terhadap keberhasilan pembibitan. Persentase setek berakar meningkat pada perlakuan pucuk dibandingkan ruas pertama setelah pucuk dengan perlakuan ZPT bawang merah 50%.

Vetiver (Vetiveria zizanioides L.) plants are able to protect the soil from erosion and are tolerant of salinity stress. However, at high salinity levels, vetiver plants show a decreasing growth. The application of gibberelin is expected to increase the growth of vetiver in salinity stress conditions. The purpose of this study was to evaluate the growth responsiveness and production of vetiver the application of gibberelin under salinity stress conditions. This research was conducted in the green house of the Faculty of Agiculture, Universitas Sumatera Utara, Medan. This study used a non-factorial completely randomized design, namely the salinity stress (S) which consisted of 3 levels, each treatment was repeated 3 times, so that 9 treatment combinations were obtained: the concentration of gibberelin was 0 (no treatment), 50 ppm and 100 ppm.

Latar belakang penelitian ini yaitu adanya serangan hama PBKo di lahan kopi PT.Wahana Graha Makmur Kecamatan Sidiangkat Kabupaten Dairi yang menyebabkan penurunan produktivitas dan kualitas hasil yang nyata yakni mencapai 10- 40%. Metode pengendalian hama terpadu, khususnya penggunaan perangkap atraktan yang terbuat dari limbah kopi, dianggap sebagai solusi potensial. Penelitian ini dilakukan untuk melihat efektivitas pengendalian hama PBKo menggunakan atraktan kulit kopi dan perangkap botol warna. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) Faktorial dengan 2 faktor dimana faktor pertama yaitu atraktan kulit kopi dengan 3 taraf dosis yaitu kontrol/tanpa atraktan, atraktan dosis 30%, dan atraktan dosis 50%. Faktor kedua yaitu perangkap botol dengan 3 warna yakni botol transparan, botol warna kuning, dan botol warna merah. Pelaksanaan penelitian dimulai dengan menghitung persentase buah kopi yang terserang, dilanjutkan dengan pengamatan jumlah hama PBKo yang terperangkap. Hasil penelitian menunjukkan perlakuan atraktan dengan dosis 50 % dengan kombinasi dengan botol warna merah merupakan perlakuan terbaik dalam pengendalian hama PBKo.
