Industri sawit di Indonesia mengalami perkembangan yang pesat, terlihat dari meningkatnya luas perkebunan sawit, baik perkebunan rakyat maupun milik perusahaan. Pencemaran yang ditimbulkan dari industri kelapa sawit dan potensi bahan organik yang terkandung dalam limbah kelapa sawit, menuntut suatu perkebunan kelapa sawit untuk mengelola limbahnya. Salah satu limbah yang dihasilkan dari perkebunan kelapa sawit adalah limbah cair yang keluar dari pabrik dan membentuk endapan padat di kolam penampungan limbah yang disebut sludge. Di sisi lain tanaman kelapa sawit pada umur tertentu membutuhkan tanaman penutup tanah (LCC) dalam tahapan budidayanya, salah satunya Pueraria javanica (Pj) dan untuk dapat menjalankan fungsinya dengan baik sebagai LCC dan penambat unsur N bagi sawit maka tanaman ini harus tumbuh dengan baik pula. Oleh karena itu dilakukan penelitian mengenai pengaruh sludge terhadap pertumbuhan Pueraria javanica dengan harapan limbah sludge dapat dimanfaatkan dengan baik sebagi panambah unsur hara bagi Pueraria javanica. Penelitian ini bertujuan mengetahui dosis terbaik pemberian sludge terhadap pertumbuhan Peuraria javanica. Penelitian ini disusun dalam Rancangan Acak Kelompok Lengkap (RAKL) Non faktorial dengan 4 perlakuan dan 3 ulangan dalam bentuk blok. Perlakuan tersebut terdiri dari P0 sebagai kontrol (Tanpa Pemberian Sludge); P1 (Sludge 100 gram); P2 (Sludge 200 gram); dan P3 (Sludge 300 gram). Hasil penelitian menunjukkan bahwa pemberian sludge 300 gram mampu menghasilkan pertumbuhan terbaik Peuraria javanica dari sisi panjang sulur, jumlah daun, diameter sulur, jumlah bintil akar, bobot basah, dan bobot kering tanaman. THE EFFECT OF OIL PALM SLUDGE ON THE GROWTH OF Pueraria javanica The palm oil industry in Indonesia is rapidly development, from the increasing area of oil palm plantations. Pollution caused by the palm oil industry and the potential for organic matter contained in palm oil waste, requires an oil palm plantation to manage its waste. One of the wastes produced is liquid waste that comes out of the factory and forms solid deposits in the waste collection pond called sludge. Oil palm plants needs legume cover crops (LCC) in the stages of cultivation, one of which is Pueraria javanica (Pj) and to be able to carry out their functions properly as LCC and binder N, this plant must grow well as well. Therefore, a study was conducted on the effect of sludge on the growth of Pueraria javanica in the hope that the sludge waste can be utilized properly as a nutrient addition for Pueraria javanica. This study aims to determine the best dose of sludge on the growth of Peuraria javanica. This study was arranged in a Randomized Completely Block Design (RCBD) with 4 treatments and 3 replications in the form of blocks. The treatment consisted of P0 as a control (without sludge); P1 (sludge 100 grams); P2 (sludge 200 grams); and P3 (sludge 300 grams). The results showed that the administration of 300 grams of sludge was able to produce the best growth of Peuraria javanica in terms of tendril length, number of leaves, tendril diameter, number of root nodules, wet weight, and plant dry weight.

Coffee waste contains a large amount of nutrients, making it a potential raw material for compost fertilizer. The nutrients contained in coffee waste include N, P, K, Mg, and Ca. Utilization of coffee waste as compost requires bioactivators to accelerate the decomposition process. This study aims to determine the difference in compost quality from coffee waste by using bioactivators in the form of local microorganisms (LMO) of cassava tapai. This study was conducted from April to May 2023 at the greenhouse of LPP Polytechnic Yogyakarta, consisting of two stages: making the LMO and making the compost. Cassava tapai LMO was prepared as a treatment for composting coffee waste. Each treatment was repeated three times. After that, the fermentation results in the form of compost were tested, then the results were compared with the standards of the Decree of the Minister of Agriculture No. 261/KPTS/SR.310/M/4/2019 on the minimum technical requirements for organic fertilizers, biological fertilizers, and soil conditioners. The results reveal that the provision of cassava tapai LMO bioactivator affected the quality of coffee waste compost produced. The quality of composts produced from control, cassava tapai LMO of 90 ml, and EM-4 treatment does not meet the standards of the Decree of the Minister of Agriculture in the parameter of chemical properties, namely the C/N ratio. The quality of compost produced from cassava tapai LMO of 120 ml meets the standards of the Decree of the Minister of Agriculture and SNI 2004 in all parameters of physical properties, chemical properties, and nutrient content.

Sugarcane (Saccharum officinarum L.) is a plantation crop that is used as raw material for the consumer sugar and industrial sugar. The need for sugar is increasing every year but is not matched by an increase in sugarcane production due to several factors including cultivation management that is not optimal. Sugarcane production begins with good nursery management, including using genetic of seeds and the right planting media. One alternative to improve the quality of growing media is to use humic acid (HA) as a soil enhancer. This study aims to determinate the effect of giving HA on the morphological characteristics of sugarcane seedlings of Bululawang variety (BL). This research was carried out in an integrated laboratory greenhouse at the Polytechnic LPP Yogyakarta from Maret to July 2021. This study used a non-factorial completely randomized design (CRD) with five treatments and three replications consisting of P0 (control), P1 (25 ml.polybag-1), P2 (50 ml.polybag-1), P3 (75 ml.polybag-1), and P4 (100 ml.polybag-1). The morphological characteristics observed is plants height (cm), number of leaves (strands), stem diameter (mm) and longest root length (cm). the results of the study were analyzed using ANOVA at the 5% level and continued using the Duncan Multiple Range Test (DMRT) at the 5% level. The result showed the effect on morphological characters on all observation variables where the P3 treatment had the best growth and morphological characters, so that in general the additional of HA affected the morphological characteristics of sugarcane seedlings of BL varieties.

Grape (Vitis vinifera) cultivation is hampered by a lack of suitable land and challenging nurseries. Use of crimson yellow podzolic soil for vine cuttings can be suboptimal. Although podzolic soil has a low capacity to absorb macro- and micronutrients and an acidic pH, it can nevertheless be used as a growing medium. A synthetic growth regulator (ZPT) bath of naphthalene acetic acid (NAA) needs to be added to the local red master grape variety, which has started to develop as a scion in nurseries. In order to assess the impacts of NAA-soaked concentrations on podzolic soil media and identify the morphological traits of local Red Master grape cuttings, this study set out to identify these traits. Its goal was to find out how auxin affected the development and yield of grapes (Vitis vinifera L.) grown in red yellow podzolic soil. A non-factorial totally randomized design with one factor (NAA concentration) was used in the study, with a block of 4 treatments and 3 repetitions. The varied NAA concentrations used in the treatment procedure included F0 (0 g L-1), F1 (2 g L-1), F2 (4 g L-1), and F3 (6 g L-1). The variables that were observed included the number of shoot bursts, the timing of leaf emergence, the number of sheet leaves, the length of the tendrils, and the proportion of live cuttings. ANOVA was used to tabulate and analyze observational data at a 5% level, and DMRT analysis was used to continue the analysis at the same level. According to the results, soaked NAA at a concentration of 0 g L-1 (S0) as the control treatment had the best results for the variable number of shoots and leaves, while a concentration of 2 g L-1 (S1) had the best results for the variable length of tendrils. However, soaked NAA had no significant impact on the variable when leaves emerged. Soaking auxin at the bottom of cuttings had no effect on shoot formation. Reduction of auxin due to defoliation can result in the expression of the isopentenyl-transferase (IPT) gene. Auxins, such as Indole-3-acetic acid (NAA), are usually involved in the regulation of root and leaf growth. If a plant has many leaves and few roots without the use of additional NAA or auxin, several factors may play a role, such as plant genetics, environmental conditions, and environmental stress. The use of additional NAA or auxin can explicitly affect the growth of roots and leaves. The survival percentage of cuttings is still low because it is influenced by the quality (material) of the cuttings, the age of the parent tree, growing media and water availability.
