Abstract

Fertilizer is the main source of nutrients for plants in relation to growth, development and production processes every day. Manure is a waste product from pets that can be used to improve soil fertility, soil biology and soil physical properties. This study aims to determine the effect of cow manure on the growth and production of lettuce plants (Lactuca sativa L.). The experimental design used was a single-factor complete randomized design (RAL), namely the dose of cow manure. There are 5 types of cow manure treatments, namely S0 (control), S1 (600 grams / polybag), S2 (700 grams / polybag), S3 (800 grams / polybag), S4 (900 grams / polybag). The analysis used is variety analysis (anova) based on observed variables. If there is a real effect, it is followed by the smallest real difference test (BNT) level of 5%. The results of variety analysis and average difference tests show that the use of cow manure with various treatments has a very real effect on plant height, leaf area, header weight, root weight and has a real influence on the number of leaves. The dose of cow manure 600 grams / polybag can increase plant height growth, leaf area and fresh weight of plants.

Abstract

Spell analysis is one of the indicators that can be used to measure the level of vulnerability of a region to drought. This study aims to determine the chances of a series of dry days during the effective growing season during El Niño on Ambon Island. Data analysis was carried out with the following stages: (1) calculating rainfall probability at 75% using the ranking order method and potential evapotranspiration using the Penman-Monteith method in the Cropwat 8.0 Program package, (2) calculating land water balance and determining the effective growing season based on optimum soil water content, and (3) determining the years of El Niño occurrence and the chances of a series of dry days. The results of the study showed that the effective growing season on Ambon Island lasted for 7 months, from April to October. The El Niño event on Ambon Island during the period 1979–2023 tends to occur once every three years. The chances of a series of dry days ≥ 5 days during the growing season ranged from 56 to 88%; ≥ 10 days: 27 to 88%; ≥ 15 days: 7 to 80%; and ≥ 20 days: 0 to 47%.

Abstract

This research was conducted in Pelita Jaya Village, Pohon Batu Hamlet, West Seram Regency from June to July 2022. The research was conducted to study the effect of the interaction of doses of organic fertilizer from pearl oyster biofouling waste and intervals of water administration on the growth and yield of mustard plants. The design used in this study was a factorial randomized group trial design (RAK) with two treatments as follows: Factor I: Pearl Oyster Biofouling Waste Fertilizer (L) with 4 levels, namely L0 = Control, L1 = Dosage of 50 gr/tan, L = 100 g/tan and L3 = 150 gr/tan Factor II : Watering Time Interval (W) namely W1 = 1 day, W2 = 2 days and W3 = 3 days. Each treatment was combined to obtain 12 treatments with 3 replications, resulting in 36 experimental plots. In each plot, 4 sample plants were taken so that in total there were 144 sample plants. The results of this study indicate that the interaction of organic fertilizer from pearl oyster biofouling waste with intervals of watering has a very significant effect on the growth and yield of mustard plants (number of leaves, leaf area, plant fresh weight and plant dry weight). The best treatment interaction was the combined dose of pearl oyster biofouling waste fertilizer 150 g/tan with an interval of watering once every three days for mustard greens (Brassica juncea L.)

Abstract

Clove production in Maluku fluctuates from year to year, one of which is influenced by rainfall anomalies. This study aimed of describing extreme rainfall events and analyzing the relations between rainfall and clove productivity in two areas with different rainfall patterns in Maluku. This study used a survey method by using interviews and Focus Group Discussions with several farmer respondents as well as collecting climatic data from related agencies. Data analysis was divided into rainfall data generation, rainfall analysis in extreme conditions, and regression analysis to assess the effect of rainfall on clove productivity. The results showed that a very extreme El Nino event caused a decrease in rainfall on Nusalaut Island by 1868 mm or 57% of its normal condition, and in Air Buaya District by 875 mm or 42% of its normal condition. Very extreme La Nina events caused rainfall to increase in Nusalaut Island by 2059 mm or 62% of its normal condition, and in Air Buaya District by 1193 mm or 37% of its normal condition. The results of the regression analysis showed that the value of the coefficient of determination (R²) for Nusalaut Island by 84.8% and for Air Buaya District by 70.8%; this shows that rainfall has a significant effect on clove productivity.

Abstract

Most of the nutmeg cultivation systems in Maluku are smallholder plantations. Agroforestry has long been developed in Maluku for generations known as dusung. Dusung can increase farmers' income continuously because the harvest is done weekly, monthly, yearly. The problems faced by farmers in Maluku regarding the productivity potential of nutmeg plants are caused by factors such as plant age, plant cultivation techniques and conventional processing. Based on these problems, a study was conducted to obtain data and information about hamlet-based nutmeg cultivation systems and productivity in Kairatu Barat District. The data and information are useful in the context of improving hamlet-based nutmeg cultivation systems in Kairatu Barat District, West Seram Regency in the future. The research uses survey methods and direct observation in the field. The selection of respondents was carried out by purposive sampling. Respondents amounted to 32 farmers. Sampling was carried out using Stratified Random Sampling, strata were determined based on the number of nutmeg plants per farmer and samples were taken randomly from each farmer. Data collected in the form of primary and secondary data. The research was carried out during the 2022 harvest season. The results of the research indicated that the cultivation system and production of nutmeg in West Kairatu District (Kamal village, Nuruwe, Lohiatala) is classified as low. Due to the number of nutmeg plants that produce began to decline. the seeds used as seeds still come from sweeping seeds. Control of Plant Destruction Organisms is carried out only when the plants start producing and fertilization is never done. Overall, the farmers in the research location cultivate hamlet-based nutmeg plants.

Abstract

Ketersediaan nutrisi berperan penting dalam mengatur fungsi fisiologis tanaman, termasuk pembentukan dan kerapatan stomata yang memengaruhi efisiensi fotosintesis serta penggunaan air. Salah satu sumber nutrisi organik potensial adalah Pupuk Organik Cair (POC) berbasis biofouling Tiram Mutiara, yang mengandung unsur hara esensial seperti nitrogen, fosfor, dan kalium. Penelitian ini bertujuan untuk menganalisis pengaruh konsentrasi dan frekuensi aplikasi POC biofouling Tiram Mutiara terhadap kerapatan stomata tanaman hotong (Setaria italica (L.)). Penelitian dilaksanakan di Desa Mamala, Kabupaten Maluku Tengah, dari Oktober 2023 hingga Januari 2024, menggunakan rancangan acak kelompok lengkap (RAKL) dua faktor, yaitu konsentrasi POC (0, 10, 20, dan 30 mL/L) serta frekuensi aplikasi (satu kali pada 25 Hari Setelah Tanam [HST] dan dua kali pada 25 dan 50 HST). Hasil analisis varians menunjukkan bahwa kedua faktor berpengaruh signifikan terhadap kerapatan stomata, tinggi tanaman, dan jumlah daun. Perlakuan P3W2 (30 mL/L, dua kali aplikasi) memberikan nilai tertinggi dengan kerapatan stomata 366,67 stomata/cm². Hasil ini menunjukkan bahwa peningkatan konsentrasi dan frekuensi aplikasi POC biofouling meningkatkan aktivitas fisiologis tanaman melalui pembentukan stomata yang lebih padat dan efisien. Dengan demikian, POC biofouling Tiram Mutiara berpotensi digunakan sebagai pupuk organik ramah lingkungan yang mendukung pertumbuhan dan efisiensi fotosintesis tanaman hotong.  Nutrient availability plays a crucial role in regulating plant physiological functions, including stomatal formation and density, which directly affect photosynthetic efficiency and water use. One promising organic nutrient source is Pearl Oyster biofouling-based liquid organic fertilizer (POC), which contains essential elements such as nitrogen, phosphorus, and potassium. This study aimed to examine the effects of different concentrations and application frequencies of Pearl Oyster biofouling POC on the stomatal density of foxtail millet (Setaria italica (L.)). The research was conducted in Mamala Village, Central Maluku Regency, from October 2023 to January 2024, using a randomized complete block design (RCBD) with two factors: POC concentration (0, 10, 20, and 30 mL/L) and application frequency (once at 25 Days After Planting [DAP] and twice at 25 and 50 DAP). Analysis of variance revealed significant effects of both factors on stomatal density, plant height, and leaf number. The highest stomatal density (366.67 stomata/cm²) was observed in treatment P3W2 (30 mL/L applied twice). These findings indicate that higher concentrations and more frequent applications of biofouling-based POC enhance plant physiological activity by promoting denser and more efficient stomatal development. Therefore, Pearl Oyster biofouling POC can serve as an environmentally friendly organic fertilizer that supports improved growth and photosynthetic efficiency in Setaria italica (L.).

Abstract

This greenhouse study investigated the impact of Biotogrow liquid organic fertilizer concentration and application frequency on lettuce (Lactuca sativa L.) growth and yield at Telaga Kodok from May to August 2024. The purpose of the research is to determine the effect of Biotogrow Liquid Fertiliser concentration and fertilisation interval, as well as the interaction between the two, on the growth and production of lettuce (Lactuca sativa L.). Using a factorial Randomized Complete Block Design with three replications, researchers tested four Biotogrow concentrations (0, 2, 5, and 8 ml L⁻¹) and four fertilization intervals (0, 4, 7, and 10 days). Growth parameters, including plant height, leaf number, leaf area, fresh weights, shoot-to-root ratio, and harvest index, were measured at 14, 21, 28, and 35 days after planting. ANOVA and Duncan's Multiple Range Test (α = 0.05) revealed significant findings. Biotogrow concentration substantially influenced plant height at 21, 28, and 35 DAP (P < 0.01), leaf number throughout all observation periods (P < 0.05 at 14 DAP; P < 0.01 thereafter), plus shoot and root fresh weight, leaf area, and harvest index (P < 0.01). Fertilization intervals significantly affected all parameters except the shoot-to-root ratio (P < 0.01). Importantly, concentration-interval interactions showed highly significant effects on leaf number at 35 DAP, shoot fresh weight, and leaf area (P < 0.01), with significant impacts on plant height at 28 and 35 DAP, leaf number at 28 DAP, and root fresh weight (P < 0.05). These results demonstrate that optimizing both Biotogrow concentration and application timing can significantly enhance lettuce productivity under greenhouse conditions.
