This study aims to delineate the intricacies of the composting process and elucidate the characteristics of compost derived from recycling centers/compost houses in Surabaya City, Indonesia. Employing a qualitative descriptive approach, this research scrutinized the composting process by delving into the origins of raw materials, procedural stages, and the chemical composition of the resultant compost. The composting materials encompassed household waste, market refuse, and fall foliage. Notably, composting occurred within an open aerobic system devoid of bio-activators. Chemical analysis revealed: C/N ratio (17.10 - 19.60), C-total (17.65% - 18.10%), N-total (0.95% - 1.12%), P2O5 (0.35% - 0.51%), K2O (0.39% - 0.41%), Cu (1.65 ppm - 2.01 ppm), Pb (2.05 ppm - 3.11 ppm), Cd (0.11 ppm - 0.24 ppm), and Zn (1.02 ppm - 1.14 ppm). Physically, the compost manifested as a dark brown substance, exhibiting a soil-like softness attributable to grinding, with temperatures oscillating between 41.90 to 55.00°C. Visually, the compost appeared mature and primed for utilization based on color and texture criteria; however, indicators such as C/N ratio and temperature suggest an immature state rendering the compost unsuitable for immediate planting. To ensure optimal maturity conducive to plant growth, it is recommended that users store the compost for a minimum of one month before application, thereby fostering its maturation process.","PeriodicalId":55737,"journal":{"name":"Jurnal Ilmiah Pertanian","volume":"27 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140363366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biofertilizers can be applied to reduce the reliance on chemical fertilizers, promoting soil health and fertility by providing essential macro and micronutrients for better plant growth. This study aimed to determine the optimal dosage and method for the combined application of biofertilizer, biosurfactant diethanolamide (DEA) palm olein, and neem extract on avocado seedlings. The experimental design used was a factorial randomized complete block design with two factors. The first factor was the biofertilizer dosage (B) and the second factor was the application method (M). Results indicate that a 10 mL/L biofertilizer dosage, 5% DEA, and 35% neem extract show the best effects on plant height, leaf chlorophyll levels, stem diameter, and the number of avocado leaves. The application method of applying to the planting medium yields the best results for plant height, leaf count, and leaf chlorophyll levels. There was an interaction between treatments regarding plant height at 10 weeks after transplanting (WAT) and leaf count at 8 WAT.

Control measures using synthetic pesticides have been implemented but yielded unsatisfactory results. The utilization of resistant varieties stands as a pertinent approach in early control efforts to minimize harvest losses. Additionally, the use of resistant varieties is a crucial component of integrated disease control implementation. This study aims to investigate the resistance levels of ten chili varieties commonly grown in swampy areas against specific isolates of Colletotrichum sp. present in swampy locations. The research, conducted in a randomized complete design in a greenhouse, tested ten varieties of cayenne pepper typically cultivated in swampy areas. The results revealed that the Hiyung variety is Susceptible, while Bara, Dewata 43 F1, Tiung Tanjung, Genie, Sekar, and CR-9 varieties exhibit moderate resistance. Conversely, Tiung Ulin, Alip, and Sret varieties are classified as resistant. The incubation period for tested cayenne pepper varieties varied, ranging from 3.5 to 5.3 days. A longer incubation period indicates greater resistance to anthracnose in chili varieties. The selection of resistant varieties is a pivotal step in anthracnose management, not only to minimize harvest losses but also to support an effective integrated control approach.","PeriodicalId":55737,"journal":{"name":"Jurnal Ilmiah Pertanian","volume":"14 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139156851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aims to evaluate the effect of 6-benzylaminopurine (BAP) in inducing shoots and determine the optimal BAP concentration on tembesu petiole explants in vitro. A completely randomized design (CRD) with six treatment levels (0, 0.5, 1, 1.5, 2, and 2.5 mg/L BAP) and five replications was employed. Despite a 10% shoot formation rate for each treatment, the optimal BAP concentration for callus formation was found to be 0.5 mg/L, with the highest percentage reaching 70%. The results indicate that adding different concentrations of BAP to the Murashige & Skoog (MS) medium was ineffective in inducing shoots in tembesu petiole explants. Therefore, further research and the development of more sophisticated in vitro propagation techniques are necessary to enhance the success of shoot induction in tembesu. It is hoped that this research will serve as a foundation and motivation for subsequent in-depth studies on the in vitro propagation of tembesu, supporting the conservation and development of this plant.","PeriodicalId":55737,"journal":{"name":"Jurnal Ilmiah Pertanian","volume":"286 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139160981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
