Abstract

Sengon (Falcataria moluccana) cultivations still have to face threats from plant diseases. Diseases can be found in nurseries and plantation. Biological agents can be used to control various types of plant diseases and have various advantages. The use of biological agents in forestry plantations must consider the aspects of effectiveness and efficiency. This study aims to examine the effect of various treatment of control technology packages on the incidence of major diseases, and to determine the financial feasibility of various disease control technology packages for sengon in nurseries. The research was conducted through interviews to explore cultivation techniques and production costs. In addition, experiments were carried out on the application of various disease control strategies using commercial formulations of biological agents. The commercial formulations of biological agents used were Rhizomax, Primagrain, Trichowish, Kayabio, Bio-Hara Plus, and fungicide Dithane M-45 80 WP. There were two treatment packages of new technology that have an effect on increasing the growth of sengon at the beginning of growth stage, namely P1 (BioHara Plus and KayaBio) and P2 (Rhizomax and Primagrain) treatments. All treatments of the new technology package had no significant effect on increasing the survival rate and suppressing the incidence and severity of disease in sengon seedlings. All new technology package treatments can generate profits even though the value is smaller when compared to existing technology treatments. All the new technology package treatments have an R/C ratio of more than 1 so that they are feasible to be applied by farmers.

Abstract

Meloidogyne sp. is one of the main constraints of tomato production in Indonesia. Endophytic bacteria may be considered as biocontrol agents for controlling Meloidogyne sp. The objective of this study was to isolate endophytic bacteria from forestry plants and to evaluate its potential for controling Meloidogyne sp. on tomato. Endophytic bacteria were isolated from roots of mahoni (Swietenia mahogany), trambesi (Albizia saman), gaharu (Aquilaria malacensis), and meranti (Shorea sp.). Isolation of bacterial endophytes from plant tissue was conducted using surface sterilization method with 70% alcohol, 3% NaOCl and sterile water on medium trypsic soy agar. Endophytic bacteria was separated and purified based on shape and color of the colony. A total of 33 isolates of endophytic bacteria were isolated from roots of mahoni (11 isolates), trambesi (5 isolates), gaharu (7 isolates), and meranti (10 isolates). The bacteria was tested for the hypersensitivity reaction on tobacco plants and the result showed that 22 isolates did not cause necrosis, indicated they are not pathogenic. Ten isolates of endophytic bacteria was selected for further experiment, i.e. to evaluate their potential as biocontrol agent for Meloidogyne sp. and as growth promotor for tomato plants. The experiment was conducted in the screenhouse using seed treatment. The result showed that two isolates of endophytic bacteria, i.e. MSJ1H and AGS1F were able to increase the growth of tomato plants up to 60% and reduce the number of root knot caused by Meloidogyne sp. Endophytic bacteria isolated from forestry plants have the potential as a biocontrol agents to plant parasitic nematode Meloidogyne sp.

Abstract

The coffee berry borer (CBB), caused by the Hypothenemus hampei Ferrari insect, is a significant pest for coffee farmers, particularly attacking the berries and affecting both the quality and quantity of coffee production. CBB attacks can reduce the quantity and quality of coffee plant production. CBB can be controlled by using botanical pesticides. One such botanical pesticide is derived from the Piper aduncum L. plant, which contains various compounds including dilapiol, piperamidin alkaloid, flavonoids, saponins, steroids, polyphenols, tannins, and terpenoids. This study aimed to test the effectiveness of botanical pesticides from P. aduncum L. in controlling CBB. This experiment used a non-factorial randomized block design (RBD) with one factor studied, namely the effect of variations in the provision of botanical pesticides of Piper aduncum L. with treatments P0 = control; P1 = 15%; P2 = 25%; P3 = 35%; and P4 = chemical pesticides. This experiment consisted of 5 treatment levels with three replications, each containing ten pests. The results showed that treatment P3 (35%) was the most effective concentration in controlling CBB. Botanical pesticides at a concentration of 35% had the same effect as chemical pesticides on the parameters of mortality observation and suppression of pest attack intensity.

Abstract

In vocational education, field practice is not only considered as a complement, but also as the core of learning that can produce graduates who are ready to contribute directly to the world of work. Professional Job Lecture (PJL) is a mandatory courses in the sixth semester. All learning is carried out practically. This research aims to examine the level of knowledge of students who are participants in the PJL. The research was conducted on 15 August until 31 October 2023 at the Citra Widya Edukasi Oil Palm Polytechnic on all students of the Production Technology of Plantation Crops study program for the year entering 2021. The number of students in the survey was 37 people. The student has participated in PJL activities at the Subang oil palm educational plantation of the Citra Widya Edukasi Oil Palm Polytechnic for 20 days. Primary data was used in this research through filling out questionnaires. Level of confidence and knowledge of students measured by submitting statements and questions in online questionnaire. Questionnaire-filling was carried out on the first day of the PJL and 2 months after the activity was completed. The level of knowledge of students PJL about oil palm plantation management was medium to very high level based on hypothetical data categorization. The majority of students have a high level of knowledge as much as 62.86%. Effective communication based on SKKN topic for Plantation Asisstants was the highest percentage of corecct answers namely 89.86. Self-confidence was increased after PJL with the number of students by 31 people.

Abstract

Kelompok tani maduhur di Kecamatan Taman Sari, Kabupaten Bogor merupakan petani kopi. Beberapa jenis kopi ditanam diantaranya kopi arabika, robusta, liberika, dan kopi kultivar lokal yakni kopi “buhun”. Kelompok tani maduhur dalam teknis budidaya kopi masih mengalami beberapa kendala, diantaranya ketersediaan bibit unggul, kondisi agroklimat serta serangan hama dan penyakit. Hal ini menyebabkan potensi produksi dari tanaman kopi belum optimum. Sedangkan di pasaran permintaan kopi terus meningkat dan menuntut kualitas yang prima. Oleh karena itu, kelompok tani maduhur diberikan pendampingan dan inisiasi pusat pengembangan kopi khususnya di Kecamatan Tamansari, Kabupaten Bogor. Hasil diskusi dan wawancara dari petani kopi menunjukkan minimnya pengetahuan teknis budidaya kopi. Tingkat pengetahuan petani masih terbilang minim sehingga hasil produksi yang diperoleh belum mencapai target. Kesimpulan dari kegiatan pengabdian kepada masyarakat ini berupa penyuluhan mengenai teknik budidaya kopi sesuai dengan kondisi aktual di lapangan dan memberikan arahan kepada seluruh anggota kelompok tani untuk mempraktikkan materi yang telah diberikan.
