Floating culture system (FCS) is the only feasible way for crop cultivation during high and prolonged flooding period at riparian wetlands. Objective of this research was to evaluate growth and yield of chili pepper cultivated using three different FCS during high flooding period at tropical riparian wetland. Floating rafts were constructed using used plastic bottles. Dimension of the raft was 2m x 1m with load capacity of 60 kg m-2 ; therefore each raft can carry 120 kg dead weight of growing media and chili pepper grown on it. Chili pepper used was CK9856 variety. Three FCS treatments applied were: P 1 , with gunny sack layer placed at interface between water surface and growing media; P 2 , without gunny sack at the interface; and P 3 , bottom part of growing media was immersed in water at 2-3 cm depth. These treatments were compared to P 0 , conventionally cultivated chili pepper as control. Result of this study revealed that chili pepper cultivated using FCS (P 1 , P 2 , and P 3) significantly outperformed those of conventionally cultivated (P 0) as indicated by higher growth and yield. Among FCS treatments, P 2 produced the highest marketable yield (248.9 g plant-1). Therefore, the P 2 is recommended for cultivation of chili pepper by smallholder farmers at riparian wetlands during high and prolonged flooding period.

Abstract. Gustianingtyas M, Herlinda S, Suwandi, Suparman, Hamidson H, Hasbi, Setiawan A, Verawaty M, Elfita, Arsi. 2020. Toxicity of entomopathogenic fungal culture filtrate of lowland and highland soil of South Sumatra against Spodoptera litura larvae. Biodiversitas 21: 1839-1849. The use of secondary fungal metabolites for the active ingredient of mycoinsecticide is more effective and more easily integrated with other pest control techniques. This study aimed to measure the toxicity of the culture filtrate of entomopathogenic fungi originating from South Sumatra against the Spodoptera litura larvae. Beauveria bassiana (25 isolates) and Metarhizium anisopliae (20 isolates) of South Sumatra were cultured in liquid media and filtered to produce culture filtrate. The larvae which were sick due to the filtrate showed the symptoms of decreased appetite and were not actively moving, while the dead larvae were characterized by being wrinkled, dry, black integument, and odorless. Mortality caused by B. bassiana filtrate was the highest 98% (BJgTs isolate) and not significantly different from the BSwTd2 isolate (94.67%). Yet, the LT50 BSwTd2 isolate was shorter (5.92 days) compared to the LT50 BJgTs isolate (6.35 days). The most toxic M. anisopliae filtrate produced the mortality of 96% (MKbTp2 isolate) and 85.33% (MPdB isolate) each of which had LT50 of 7.36 days and 8.09 days, respectively. So, the most toxic culture filtrate was BSwTd2 isolate of B. bassiana and MKbTp2 isolate of M. anisopliae. The entomopathogenic fungi producing filtrate which are toxic have the potential to be active ingredients of mycoinsecticides.

Purpose of the study: The rambu solo’ ceremony is a traditional death ceremony of the Tana Toraja regency with roots in local beliefs. However, over time, the tradition has become associated with social status and economic motives. These changes have led to many issues. This article analyses the motivations that drive the compromises that families must accept when selecting a form of rambu solo’. Methodology: This was a case study conducted in the village of Lemo in the regency of Tana Toraja. Primary data collected through in-depth interviews and observation. Informants consisted of cultural figures, religious figures, and indigenous locals with experience performing rambu solo’ — secondary data taken from existing literature about Toraja Regency. Main Findings: Results showed that compromises taken for motives of social status were irrational but comprised the most common reasoning behind rambu solo’ ceremony selection. For those families motivated by social status, choice of rambu solo’ ceremony form performed for one of two reasons: preserving their social status ascribed to them from birth (attributed status) Applications of this study: The selection of non-rapasanrambu solo’ ceremonies based on economic motives were rationally-sound but relatively rare. Avoiding wastefulness in the performing of rambu solo’ is done through simplifying the procession through shortening the storage period of the remains of the deceased before the rambu solo’ reducing the number of days of the rambu solo’ ceremony. Novelty/Originality of this study: This shows that irrational decision-making, in the context of traditional ceremonies, cannot be considered irrational; even irrational decisions can be justified and explained based on individual interpretations of rationality based on local culture. Interestingly, social status was the most common motive form selection based on economic motives were rational but less popular among the people sound choice theory

Abstract. Herlinda S, Efendi RA, Suharjo R, Hasbi, Setiawan A, Elfita, Verawaty M. 2020. New emerging entomopathogenic fungi isolated from soil in South Sumatra (Indonesia) and their filtrate and conidial insecticidal activity against Spodoptera litura. Biodiversitas 21: 5102-5113. This study was carried out to confirm identity of Beauveria bassiana and Metarhizium anisopliae using sequence analysis of Internal Transcribed Spacer (ITS) region as well as the two unknown isolates of EPF and to investigate their filtrate and conidial insecticidal activity against S. litura larvae. The EPF species were identified based on morphological characters and molecular analysis. Their culture filtrate and conidial bioassays were performed on S. litura larvae. The species found were Penicillium citrinum (BKbTp), Talaromyces diversus (MSwTp1), B. bassiana (BSwTd4), and M. anisopliae (MSwTp3) and have been deposited in the GenBank. All EPF species have high insecticidal activity against S. litura larvae. The highest larvae mortality caused by filtrate was found on P. citrinum (98.67%) and not significantly different from those of T. diversus (96%), but significantly different from B. bassiana (86.67%) and M anisopliae (82.67%). The highest larvae mortality caused by the conidia was also occurred to P. citrinum (98.67%) which was not significantly different from those of T. diversus (97.33%), B. bassiana (86.67%), and M. anisopliae (86.67%). The LT50 caused by T. diversus filtrate was the shortest (6.19 days) and not significantly different from those caused by P. citrinum (6.62 days). The shortest LT50 caused by conidia was found on P. citrinum (5.45 days). Therefore, the conidia and filtrate of P. citrinum, a new emerging entomopathogenic fungus, has the highest insecticidal activity. P. citrinum has the potential to be developed into commercial mycoinsecticides.

Decentralization is a policy for regions to maximize the functions of a regional government authority. Proportional and optimal power in mobilizing every resource in the area will make the region have independence in developing the part. The method used is a literature study; besides, the authors also use media such as newspapers, magazines, bulletins, and other sources relating to the discussion as reference material in reviewing the debate, analysis using descriptive-analytic methods. Decentralization implemented in the city of Makassar has made a very positive contribution to the people of Makassar, because, with devolution, the Makassar city government can plan its development independently for the sake of a sustainable city. The implementation of decentralization in the town of Makassar has implications for the progress of regional development; this can see in the physical event in the city and the level of economic growth

Abstract. Hanif KI, Herlinda S, Irsan C, Pujiastuti Y, Prabawati G, Hasbi, Karenina T. 2020. The impact of bioinsecticide overdoses of Beauveria bassiana on species diversity and abundance of not targeted arthropods in South Sumatra (Indonesia) freshwater swamp paddy. Biodiversitas 21: 2124-2136. Bioinsecticides have been shown to reduce insect pest populations, but it is necessary to monitor the effect of bioinsecticide overdoses on non-target arthropods because they are abundant in rice fields. This study aimed to analyze the impact of bioinsecticide overdoses of B. bassiana on species diversity and abundance of non-target arthropods. Bioinsecticides derived from Beauveria bassiana were sprayed on the paddy every two weeks until the ripening stage, at a dose of 1, 2, 3, 4 L.ha-1, control (without insecticide), and abamectin as prescribed. The abundance of spiders and predatory arthropods did not decrease when bioinsecticides were applied but the abundance of spiders, especially Lycosidae and Salticidae dropped significantly when abamectin was applied. The abundance of the parasitoid decreased significantly when abamectin was applied, but the abundance of parasitoids applied by bioinsecticide was not significantly different from those of control. The abundance of insect pests started to decrease when bioinsecticide was applied to 2, 3 or 4 L.ha-1. The diversity species of non-target arthropods (spiders, predatory arthropods, and parasitoids) tended to decrease when it was applied bioinsecticides 3 and 4 L.ha-1 or abamectin, but their abundance remained high and no species dominance was found. For this reason, the correct dosage for suppressing insect pests abundance by not decreasing the abundance and diversity of non-target species is 2 L.ha-1 and applied when herbivore abundance is high.

Bali cattle as one of Indonesia’s native cattle have horns basically, both male and female. However, in its development, Bali cattle without horns have been found and known as polled. Bali polled is cattle whose horns do not grow naturally. The objective of this study was to determine the characteristics of libido and the concentration of testosterone in Bali polled and horned bulls. The samples were 8 individuals (4 polled and 4 horned) with an age between 3-8 years. Libido characteristics were measured by recording the time the bull first fondled the cow until ejaculate and analyzing the testosterone concentration using the enzyme-linked immunosorbent assay (ELISA) method. The collected data were analyzed by an independent sample T-Test. The results of this study indicated that the time required for a polled bull from fondling the female to ejaculation was longer (P<0.05) compared to horned (7.45±2.51 vs 2.42±0.60 minutes). While the testosterone concentration was not significantly different (P>0.05) 6.94±2.43 ng/mL vs 3.74±1.34 ng/mL although showed a higher tendency for the horned bull at 3.2 ng/mL. In conclusion, the polled bull took a longer time from fondling the female to ejaculation compared to horned, while the concentration of the hormone testosterone was equal. However, libido characteristics have a positive correlation with the testosterone concentration with a correlation coefficient of 0.805.
