Abstract

Penelitian berjudul Respon Pertumbuhan Bibit Kopi Robusta (Coffea robusta L) Terhadap Pemberian Pupuk Organik Cair Limbah Industri dilaksanakan di Kebun Percobaan, Politeknik Negeri Ketapang, Kabupaten Ketapang, Kalimantan Barat pada Juli  sampai September 2020. Penelitian ini bertujuan untuk mengetahui manfaat pemberian konsentrasi yang berbeda dari POC limbah industri tahu terhadap pertumbuhan bibit kopi robusta. Menggunakan jenis penelitian Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dan 4 ulangan, yaitu : K0 = 0%, K1 = 25%, K2 = 50%, K3 = 75%, dan K4 = 100%. Data yang diperoleh dianalisis menggunakan ANOVA, jika berpengaruh nyata maka dilanjutkan dengan uji DMRT pada taraf α = 0,05. Hasil penelitian menunjukkan bahwa pemberian POC limbah industri tahu berpengaruh nyata pada parameter tinggi bibit, jumlah daun, panjang akar, berat basah dan berat kering, namun tidak berbeda nyata pada pertambahan diameter batang. Konsentrasi terbaik untuk pertumbuhan bibit kopi robusta adalah 75%.

Abstract

Salah satu faktor yang menghambat produktivitas kelapa sawit yaitu gulma, karena pengaruh gulma tidak terlihat secara langsung dan umumnya berjalan lambat. Metode pengendalian secara kimiawi dengan menggunakan herbisida dianggap sebagai metode paling mudah. Penelitian ini bertujuan untuk mengetahui dosis herbisida yang efektiv serta mengetahui tingkat kematian gulma setelah aplikasi herbisida isopropilamina glifosat pada perkebunan kelapa sawit belum menghasilkan (TBM). Penelitian ini dilaksanakan pada area perkebunan kelapa sawit belum menghasilkan (TBM) di perkebunan desa Pelang, Kabupaten Ketapang, Provinsi Kalimantan Barat. Penelitian ini menggunakan rancangan acak kelompok (RAK) dengan 6 perlakuan serta 4 ulangan. Hasil penelitian menunjukan bahwa herbisida isopropilamina glifosat mampu menekan pertumbuhan gulma. Berdasarkan hasil uji duncan multiple range test (DMRT) perlakuan terbaik dalam pengendalian gulma di tanaman kelapa sawit belum menghasilkan yaitu pada dosis 2,00 l/ha, mampu menekan pertumbuhan gulma secara efektif dengan konsentrasi 1,7 % dalam menurunkan bobot kering gulma total pada 2 dan 6 MSA di tanaman kelapa sawit belum menghasilkan (TBM).

Abstract

Young coconut water can be used as a basic ingredient in making herbicide formulas. The purpose of this study was to determine whether the concentration of the herbicide glyphosate and fermented air in controlling weeds in oil palm plantations yielded and to determine the most effective concentration in controlling weeds in oil palm plantations. This study used a Randomized Block Design (RAK) which was arranged in a factorial manner. The first factor is the concentration of the herbicide combination (H) consisting of: H1 = concentration of 2 ml glyphosate + 200 ml fermented coconut water, H2 = concentration of 4 ml glyphosate + 100 ml fermented coconut water. The second factor is the dose given (D), namely: D1 = 0.2 l/8 m2, D2 = 0.4 l/8 m2 and D3 = 0.6 l/8 m2. Each treatment was repeated 3 times. The data obtained were analyzed statistically by Analysis of Variances (ANOVA). If it has a significant effect, it will be continued with Duncan's Multiple Range Test (DMRT) at the 5% level. The results showed that the use of a combination of the herbicide glyphosate and fermented air was effective, the most effective concentration in controlling weeds in oil palm plantations resulted in a concentration of 2 ml glyphosate + 200 ml fermented young coconut water.

Abstract

Cocoa seeds are seeds that have easy germination properties or are called recalcitrants. The technique of storing recalcitrant seeds cannot be dried below a critical moisture content, germinates easily and is not tolerant of low temperatures, so it is necessary to modify storage using sawdust storage media so that the seeds remain of good quality. The purpose of this study was to determine the effect of various doses of sawdust on the shelf life of cocoa seeds. Besides that, it also knows the best treatment of various doses of sawdust that can increase the shelf life of cocoa seeds. This study used a completely randomized design (CRD) with 6 treatments and 6 replications so that there were 36 experimental units. Parameters observed consisted of seed moisture content during storage, moldy seeds in storage and percentage of germination in seeding. Observational data were analyzed using ANOVA. If the results have a significant effect, then continue with the Duncan Multiple Range Test (DMRT) test at a level of 5%. The results showed that the best sawdust storage medium was 180 grams (A5) which could reduce the percentage of moldy seeds in storage.

Abstract

The problem faced in rubber nurseries on a large scale is the limitation of fertile soil. An effort to overcome this problem is to utilize peat soil with rubber leaf litter compost treatment. The purpose of this study was to determine the effect of giving a dose of rubber leaf litter compost on the growth of sleeping eye stum rubber seeds and to determine the best dose of rubber leaf litter compost on the growth of sleeping eye stum rubber seedlings. The research was carried out in the experimental garden of Gg. Hj. Salbiah Delta Pawan District, Ketapang Regency, West Kalimantan from April to July 2021. The study used a single factor Completely Randomized Design (CRD) with 4 treatments and 5 replications. The treatments used were K0 = 1000 g peat soil, K1 = 300 g rubber leaf litter compost + 700 g peat soil, K2 = 400 g rubber leaf litter compost + 600 g peat soil and K3 = 500 g rubber leaf litter compost + 500 g peat. The data obtained were analyzed statistically with Analysis of Variances (ANOVA) using the SAS application version 9.0. If it is significantly different, then it is continued with the Duncan Multiple Range Test (DMRT) further test at the 5% level. The results showed that the addition of rubber leaf litter had a significant effect on shoot height, stem diameter, number of umbrellas and root length. The dose of rubber leaf litter compost 500 g rubber litter compost + 500 g peat soil is the best treatment to increase the growth of sleeping eye stumps.

Abstract

This study investigated the effect of organic fertilizer type, nutrient composition, and application method on tomato plant growth in the plantation areas of the Cianjur region, West Java. A randomized complete block design (RCBD) with factorial arrangements was employed, and data were collected using Likert scale ratings from 110 tomato plants. The analysis revealed significant differences in plant growth among different organic fertilizer types, with biofertilizers exhibiting the highest mean growth score. Moreover, fertilizers with balanced nutrient compositions resulted in superior plant growth compared to those with imbalanced compositions. Additionally, foliar spraying emerged as the most effective application method, promoting higher plant growth compared to broadcasting and banding methods. These findings highlight the importance of considering organic fertilizer characteristics and application techniques in optimizing tomato plant growth in agricultural systems.

Abstract

The use of liquid fertilizers based on local microorganisms offers a sustainable solution for enhancing soil fertility and maize production. This study provides a comprehensive literature review of 11 Scopus-indexed articles to examine the effects of these fertilizers on soil health and crop yield. The findings reveal significant improvements in soil organic matter, microbial diversity, and nutrient availability, alongside enhanced maize growth parameters such as germination, biomass accumulation, and grain yield. Despite the variability in results due to environmental factors and application methods, these fertilizers demonstrate the potential to reduce dependency on synthetic inputs and align with sustainable agricultural practices. Challenges related to scalability, economic feasibility, and long-term impacts necessitate further research to optimize their implementation in diverse agricultural settings.
