This research was conducted in divided plots with a completely randomized design/CRD 2 factors using polybags measuring 20x20 cm. The first factor was the irradiation intensity (main plot) which can be as high as 15 percent using 85% paranet shading or as low as 30 percent with 70 percent paranet shading. The second factor was the method of making the planting medium (sub-plots): compost, husk charcoal, cocopeat. For each parameter, the findings show that there was no interaction between irradiation intensity and growing medium composition. It was possible that each treatment had a different effect. In the number of leaves parameter, the irradiation intensity of 15% showed that the number of leaves was greater than the intensity of 30%. The number of stomata which were primarily used for gas exchange such as carbon dioxide (CO2) that plants need during photosynthesis could be affected by shade. Soil levels of N, P, and K nutrients also affected the number of leaves. All observed parameters did not show a significant difference in the treatment of the planting medium composition.

The productivity of Fresh Fruit Bunch (FFB) in Indonesia is relatively low with an average productivity of below 15 tonnes.ha-1.year-1,which is still very far below its potential, which is around 25 tonnes.ha-1. year-1, one of the contributing factors is the application of fertilizers. neither the type nor the dose has been done precisely. Research on Determining Fertilizer Dosage Based on FFB tonnage data for oil palm plantations has been carried out from March to October 2022 at a private oil palm plantation company located in Nunukan Regency, North Kalimantan Province. The research was carried out on an area of 812 ha which was divided into 28 blocks, consisting of 7 treatments each carried out in 4 blocks as repetition. The soil pH conditions are relatively neutral, namely between 6.0-6.9. Fertilizers used are also of various kinds, namely Urea, Rock phosphate, Muriate of potash, Kieserit and Dolomite. The dosage of fertilizer is determined based on the tonnage of fresh fruit bunches produced and compared with the dose of fertilizer according to the recommendations from the leaf sampling unit. This study uses monthly data for each block from March to October 2022 which includes: average stem weight (BJR), number of stems per tree (JJG/PKK), and productivity (tons.ha-1.month-1). The data obtained were then analyzed for variance and continued with Duncan's multiple range test. The results showed that in March, April and October there was a significant difference between the treatments where in March there was a difference in the productivity of fresh fruit bunches where the application of Urea-Rph-MOP-Kieserite fertilizer was 4.3-2.5-1 respectively. .9-2.9 respectively in kg.principle-1.year-1 (P1) shows the highest productivity. In April and October there was a significant difference in the yield per tree where in April the Urea-Rph-MOP fertilizer application treatment was 2.4-1.6-1.8 respectively in kg.principal-1 year-1 (P5) showed that the number of shoots per tree tended to be higher than the other treatments, whereas in October the number of stems per tree tended to be higher in treatment P1. However, there was no significant difference in average length weight from March to October. Thus the dosage of fertilizer can be determined based on fresh fruit bunch tonnage data as an option other than based on the results of leaf sampling units to be implemented in the field.

The application of organic fertilizers in eggplant cultivation can reduce the use of chemical fertilizers which can damage the soil in long term. The maturity of organic fertilizer to be ready for application is highly dependent on the length of the decomposition process. This study aims to determine the effect of decomposition time and dosage of goat manure on the growth and yield of eggplant plants. The research was conducted from April to June 2022 in Maguwoharjo, Depok, Sleman, Yogyakarta. This study used a factorial experiment method arranged in a completely randomized design consisting of two factors. Factor I is decomposition time consisting of 3 levels, namely: 1 month (W1); 1.5 months (W2); 2 months (W3). Factor II is the dosage of goat manure consisting of 3 levels, namely, 100 g (D1), 200 g (D2), 300 g (D3). Each treatment was repeated 6 times. Data from the study were analyzed using variance analysis and continued with DMRT test at 5% significant level. The results showed no significant interaction between the treatment of decomposition time and dosage of goat manure on all parameters. Each treatment gave a different effect on the growth and yield of eggplant plants.

Climate anomaly phenomena are increasing in frequency and duration along with the occurance of global warming phenomena. El Nino and La Nina climate anomalies have a direct impact on agriculture. This study aims to analyze the occurrence of extreme climate phenomena El Nino and La Nina in 2012-2022 in Indonesia and their impact on rainfall in South Sumatera Province which is one of the centers of oil palm plantations. The research was conducted by identifying sea surface temperature (SST) anomalies in the Pacific Ocean and classifying them into El Nino and La Nina strength levels or normal conditions. Based on the sea surface temperature anomaly, it is known that Indonesia experienced strong El Nino events in 2014-2015 and weak El Nino in 2019. El Nino causes a prolonged dry season and decreases the amount of rainfall. The La Nina phenomenon occurs in 2020-2022 with weak to moderate strength. La Nina causes a prolonged rainy season and an increase in the amount of rainfall. Normal conditions occurred in 2013, 2016, 2017 and 2018 which were marked by sst anomalies of not more than +0.5°C and -0.5 °C. During normal conditions, South Sumatra Province has an annual rainfall of 2,500 mm, rainfall is evenly distributed throughout the year, and dry months are less than 3 months that suitable for oil palm cultivation. In the last 10 years, Indonesia has experienced the El Nino and La Nina climate anomalies with increasing frequency, duration, and level of strength.

Penelitian ini bertujuan untuk mengetahui pengaruh asal bahan cangkok dan ZPT (root up) terhadap pertumbuhan Antigonon leptopus. Penelitian dilaksanakan di perumahan staf perkebunan Nenggala Estate (NGLE), Kecamatan Kandis, Kabupaten Siak, Provinsi Riau sejak bulan Februari hingga Mei 2022. Metode penelitian menggunakan percobaan faktorial yang disusun dalam Rancangan Acak Lengkap (RAL) terdiri dari 2 faktor. Faktor pertama adalah asal bahan cangkok yang terdiri dari 3 aras yaitu; batang atas, batang tengah, batang bawah. Sedangkan faktor kedua adalah dosis ZPT root up yang terdiri dari 4 aras yaitu;dosis 0 mg (ontrol), dosis 10 mg/tanaman, dosis 20 mg/tanaman, dosis 30 mg/tanaman. Data yang diperoleh dianalisis menggunakan sidik ragam (analysis of variance) pada jenjang nyata 5%. Apabila diperoleh hasil yang signifikan, maka dilakukan uji lanjut menggunakan uji jarak berganda DMRT (Duncan Multiple Range Test) pada jenjang nyata 5%. Parameter yang diamati adalah persentase cangkok hidup, panjang sulur, jumlah daun, berat segar tanaman, berat kering tanaman, panjang akar, berat segar akar, berat kering akar dan waktu tumbuh tunas dan akar. Hasil penelitian menunjukkan bahwa: tidak terdapat interaksi nyata antara asal bahan cangkok dan dosis ZPT root up pada setiap parameter pengamatan. Pemberian ZPT root up berpengaruh terhadap persentase cangkok hidup. Cangkok yang diaplikasikan ZPT memberikan persentase cangkok hidup yang lebih tinggi. Asal bahan cangkok batang tengah menunjukkan persentase cangkok hidup yang lebih tinggi. Perlakuan asal bahan cangkok memberikan pengaruh nyata terhadap parameter waktu tumbuh tunas dan akar. Perlakuan batang atas dan batang tengah waktu tumbuh tunas lebih cepat sedangkan batang tengah dan batang bawah waktu tumbuh aka lebih cepatr, Perlakuan pemberian dosis ZPT root up memberikan pengaruh nyata terhadap parameter waktu tumbuh tunas, Tanaman Antigonon leptopus dengan perlakuan asal bahan cangkok dan dosis ZPT menunjukkan pertumbuhan yang tidak berbeda nyata.

Penelitian dilaksanakan di perkebunan kelapa sawit unit Palapa Estate (PLPE), PT Ivo Mas Tunggal, Region Siak, PSM Riau yang merupakan salah satu unit usaha PT Smart Tbk terletak di Desa Bekalar, Kecamatan Kandis, Kabupaten Siak, Provinsi Riau. Peningkatan produksi minyak sawit di Indonesia diiringi dengan pembangunan pabrik kelapa sawit. Selain menghasilkan minyak sawit (CPO) Crude Palm Oil dan minyak inti sawit (PKO) Palm Kernel Oil, pabrik pengolahan juga menghasilkan limbah (by product). Limbah tertinggi yang dihasilkan berupa limbah cair (LCPKS) sekitar 65% dan tandan kosong kelapa sawit (TKKS) sekitar 21 %. Dalam upaya usaha mengurangi pencemaran lingkungan perusahaan komitmen menerapkan zero waste dengan memanfaatkan kembali limbah pabrik kelapa sawit sebagai pupuk organik. Penelitian bertujuan untuk mengetahui pengaruh aplikasi tandan kosong kelapa sawit (TKKS) dan limbah cair pabrik kelapa sawit (LCPKS) terhadap produktivitas, berat janjang rerata (BJR), jumlah janjang matang, dan karakter agronomi. Penelitian dilakukan selama 3 bulan yaitu pada tanggal 01 Maret-21 Mei 2022. Dilaksanakan menggunakan metode survei agronomi dengan menentukan blok sampel penelitian. Dipilih 4 blok, yaitu 2 blok yang diaplikasikan TKKS dan 2 blok diaplikasikan LCPKS. Data dikumpulkan berupa data primer dan data sekunder. Data produksi, BJR, jumlah janjang matang, dan karakter agronomi yang diperoleh kemudian di analisis dengan menggunakan uji t pada jenjang 5%. Hasil penelitian mengungkapkan bahwa aplikasi LCPKS menghadilkan karakter agronomi dan produksi yang lebih baik daripada tankos. Hasil penelitian ini dapat mendukung pemanfaatan LCPKS dan tankos sebagai salah satu sumber hara untuk perkebunan kelapa sawit.

This study aims to determine the plant growth parameters that most influence sugarcane productivity. The research was carried out from April 2021 to September 2021 in Argomulyo Village, Cangkringan District, Sleman Regency, Yogyakarta. This research was conducted using a survey method by taking samples of sugarcane stalks at each sampling point. The land area is 3 ha which is divided into 3 blocks, then from each block 10 sugarcane samples are taken so that there are 30 sugarcane samples. Parameters observed in this study were plant height, number of stems, stem diameter, number of leaves, number of internodes, and weight of sugarcane stalks. The results showed that the parameters that had a very high effect on productivity were stem diameter (r=0.986), number of tillers per clump (r=0.908) and sugarcane plant height (r=0.904). Meanwhile, the correlation with sugarcane stalk weight was high (r=0.879), with the number of leaves and cane stem segments very low (r=0.160 and r=0.172). Land productivity in the research location was also much lower than its potential. The addition of organic matter to improve the physical properties of the soil and increase the availability of nutrients was needed so as to increase the growth and productivity of sugarcane.
