One of the obstacles in peanut production is the attack of plant diseases, such as the fungus Sclerotium rolfsii Sacc. The use of plant-based insecticides can be an alternative to disease control in peanuts. This study aimed to obtain the appropriate and effective dose of clove leaves and flower stalks in suppressing the in vitro growth of the fungus S. rolfsii Sacc causing damping off in peanuts, and to test the effectiveness of clove leaves and flower stalks on the formation of sklerotia of the fungus. This study used ‘tuni’ clove powder from Waai Village, Salahutu District. This experimental study employed a completely randomized design (CRD) with 8 treatments and 3 replications. The results showed that the growth of the fungus S. rolfsii Sacc. was inhibited by clove flower stalk powder at a dose of 1.5 g per100 mL of PDA, which was indicated by the number of sklerotia formed of 13.67% and propagule weight of 0.12 g, followed by a dose of clove leaf powder of 1.5 g per100 mL PDA, with amount of sklerotia formed of 27.33% and propagule weight of 0.17 g.

However, its production is still not optimal because there are not many superior seeds available, which causes low productivity. One solution to this problem is to improve planting material (seeds) by a plant breeding program through a hybridization process. Crossing different types of chili requires the right time to increase the chances of success. The purpose of this study was to determine the effectiveness of crossing three genotypes of chili (two introduced and one local). The study was carried out with a factorial randomized design. The first factor was a combination of crosses of three parents, namely Sweet Italian, Garda and Katokkon by dialel crosses. The second factor was the time of crossing, namely at 04.00, 05.00, 06.00, 07.00, 08.00. The results of the analysis showed that the combination of parents had an interaction with crossing time in increasing the dsuccess of the crosses. Each parent combination hah a specific time for crossing. If the female parent was Sweet Italian, the time of crossing early in the morning (low temperature) was more optimal, which was between 04.00-07.00. For Katokkon×Garda crosses and their reciprocals, the percentage of successful crosses increased if it was done at 06.00-08.00.

Experience in recent decades has shown that the El Nino climate anomaly has caused prolonged droughts. Peanut are susceptible to drought in part or all of its growth phases due to below-normal rainfall. This study aimed to describe the occurrence of extreme El-Nino rainfall on Kei Kecil Island, Maluku Province, and how much the El-Nino events affected the planting season and peanut production on Kei Kecil Island. This was carried out using the algebraic average technique for calculating the average (normal) rainfall and the FAO (1978) method for determining the growing season. The variables observed were rainfall data and peanut plant productivity data. Data were analyzed using simple regression analysis. The results of the study showed that the El Nino phenomenon generally took place in the period from April to November; mostly starting in April, May, June and September, October and November. Drought events on Kei Kecil Island did not always coincide with El Nino events, and El Nino events did not always cause drought or rainfall below normal. In 1993, 2003, 2007, and 2012 the amount of rainfall on Kei Kecil Island was below normal (<2,308 mm per year) but these years were not recorded as El Nino years. Whereas, 1994, 2009, 2014, and 2018 were recorded as El Nino years but did not cause drought or rainfall under normal conditions on Kei Kecil Island. During the last 30 years, this incident occurred 3 times, i.e. in 1991, 1997, and 2015. The results of the analysis of the growing season showed that the planting season on Kei Kecil Island under conditions of average (normal) rainfall lasted for 289 days or 9 months 16 days (November 1 to August 16). Meanwhile, the growing season when extreme El Nino rainfall occurred, lasted for 201 days or 6 months 20 days (November 1 to May 20). This indicated that when El Nino occurred on Kei Kecil Island, there was a shift in the growing season (ending sooner).

It is responsible for significant postharvest loss resulting from moisture increase and weight reduction, wrinkling, and susceptibility to pathogen attack. Reduced root weight by water loss is associated with a higher rate of rot predominantly occurred in the developing and underdeveloped countries which can count of 8-20% of postharvest loss. Plants have different adaptation to protect themselves against skinning injury. Lignification, suberization, and increased sugar at the wound site have been shown to be correlated with wound healing. Changing in gene expressions have been associated with skinning injury. Genes associated in the biosynthesis of lignin and suberin, protein fate, cell-wall modification, transcription and protein synthesis, and stress responses and defense have been associated with skinning injury responses in plants.

Land degradation usually indicates deterioration in the production capacity of the land either temporarily or permanently. A further consequence of the land degradation process is the emergence of unproductive areas called critical lands. Quantitative and qualitative determination of erosion in a watershed area could be identified through observation of real damage indicators that had occurred in the field. This is based on this study results combined with the method of determining soil degradation in the field, namely the Field Assessment Tools, indicators of soil damage due to erosion obtained in the area of this this study area. These included pedestals, exposed plant roots / tree roots and exposed building foundations as an indication of land degradation due to sheet erosion, channel indicators as channel erosion and trench indicators as trench erosion. The classification of land degradation due to erosion found in the Wai Ruhu watershed showed that the level of land degradation could be classified as light erosion, moderate erosion, heavy erosion and very heavy erosion, with the range of erosion varying from 4.40 tons/ha/year to 675,62 tons/ha/year. Meanwhile, from the results of direct measurements, the overall average sediment concentration was 98,06 mg/L. During the rainy season, the average sediment concentration produced was 107,43 mg/L, higher than during the dry season of 88.69 mg/L. The Wai Ruhu watershed had a fairly large discharge. Although during the dry season the river was not dry completely, the discharge was very small. The basic material found along the Wai Ruhu watershed indicated that there had been intensive degradation processes in the upstream area. Excessive deposition along the river would result in reduced capacity of the river channel. \u0000Keywords: Ambon, discharge, land degradation, sedimentation, Wai Ruhu Watershed \u0000  \u0000ABSTRAK \u0000Degradasi lahan adalah berkurangnya kemampuan lahan untuk menghasilkan manfaat dan keuntungan dari penggunaan lahan tertentu di bawah perlakuan khusus dari pengelolaan lahan kerusakan lahan biasanya menandakan kemunduran kapasitas produksi dari lahan baik secara temporer maupun secara permanen.

The provision of biochar and POC leri or organic fertilizer from rice washing liquid is expected to be a long-term and sustainable solution. This study was intended to test the addition of biochar to the growing media and the application of leri on lettuce cultivation. This study used a factorial Randomized Block Design (RAK) method. The first factor was the application of biochar to the planting medium (M), which consisted of M1: Ultisol without biochar and M2: Ultisol + 30 g biochar. The second factor was the administration of liquid organic fertilizer (LOF) leri (P), with 5 treatments consisting of P0: without giving LOF leri, P1: giving LOF leri without fermentation once a week, P2: giving LOF leri without fermentation twice a week, P3: giving fermented LOF leri once a week, P4: giving fermented LOF leri twice a week. The results of this study were tested statistically by analysis of variance, with the F test; if there was a significant difference, it was continued with the BNJ test (Honest Significant Difference) at a 0.05 level. The results showed that the best treatment of LOF leri in increasing lettuce growth and yield was 25% fermented LOF leri given 2 times a week, at 250 mL per lettuce plant. As a single treatment the best growing media was M2 (Ultisol soil + 30 g of biochar) with a plant height of 25.80 cm and the leaf number of 12.83; whereas the best LOF leri treatment was P4 (fermented LOF leri given twice a week), with a plant height of 30.27 cm and leaf number of 14.42. Based on whole plant fresh weight, the best treatment was the M2P4 (Ultisol + biochar growing medium and fermented LOF leri given week), which was 185.99 g per plant. \u0000Keywords: household waste, lettuce, POC leri, rice washing liquid \u0000  \u0000ABSTRAK \u0000Melakukan budidaya tanaman sayuran, seperti selada, pada tanah Ultisol memiliki beberapa kendala, seperti kurangnya bahan organik dan unsur hara pada tanah tersebut.
