Enggano is one of the leading islands in Indonesia that has unique biodiversity. This uniqueness arises because Enggano is an ocean island that stands alone without ever becoming one with the mainland of Sumatra. Regarding its biodiversity, ethnobotany studies are needed to find out the culture of the Enggano people from ancient times to the present in the use of plants to support their lives. The Enggano people are familiar with plants that are used as food, construction, medicine, and simple technology and are still used today. The local knowledge of the Enggano community about the use of plants can provide support for their existence. Key words: culture; Enggano; ethnobotany; plant.

The Sailfin lizard is a lizard that has a semi-aquatic life and has a sail fin on its tail. These lizards can be found in habitats close to water such as rivers, lakes, and estuaries of mangrove forests. This study aimed to observe the morphofunctional characteristic of the appendicular skeleton of Sailfin Lizard (Hydrosaurus amboinensis), associated with their function and behavior. The appendicular skeleton of the Sailfin lizard was studied morphofunctional by observing and measuring the bones that make up the extremities. The naming of bones and their parts is based on the Nomina Anatomica Veterinaria 2017 and other journals. The clavicle and interclavicle bones are located anterior to the scapula coracoid which has a convex shape. The patella ulnar bone is found at the humeroulnar joint and the radius et ulna bones have a relatively long antebrachial interosseous space. On the hind legs, the coxal bone has a relatively broad acetabulum, two lunula bones and patellar mineralization are found at the craniodorsal of the femorotibiofibular joint, and tibia et fibula bones have a relatively long crural interosseous space. The palmar part of the carpal bone is found in the palmar sesamoid bone, while the tarsi bones have a fused astragalus and calcaneus bones to become astragalocalcaneus bones. The pedis skeleton's size is relatively long compared to the manus skeleton and has a different middle phalanx bone. The extremity skeletal structure allows the Sailfin Lizard to do movements such as walking, running, climbing, running on water, and swimming.Key words: appendicular skeleton; morphofunction; Sailfin lizard.

In Indonesia, maize has a number of growth constraints and one of which is climate factor. The objective of this research was to determine the growth response of local maize variety. This research was conducted by applying a factorial Randomized Block Design (RBD) with two factors. The first factor is variety (V): pulut, siropu and jakaring (comparison) while the second factor is drought treatment (K) which comprises three treatments including control, drought for 45-55 days after planting (DAP), and drought for 55-65 DAP. In this case, all treatments are repeated three times. The research revealed that the growth of maize indicate different responses towards variety as shown by parameters of plant height, soil moisture content, cob diameter, cob length, cob weight with husks, cob weight without husks, dry weight of root, and number of cob row. Meanwhile the drought stress does not indicate significant response towards growth of maize the drought-tolerant variety of maize with parameter of number of cob raw is siropu local maize.Key words: staple food; local corn; drought stress; growth.

Banana plants are a food source that has good prospects. This is because bananas are very popular with all groups, and are easy to grow in tropical areas. There are many varieties of wild and cultivated bananas that grow in Indonesia, one of which grows around Lake Sentani, causing differences in morphological characters between types and between varieties of bananas. The purpose of this study was to determine the phenetic diversity of local Sentani bananas based on morphological characters. The research was conducted in June-October 2022 in five villages around Lake Sentani, namely Ayapo, Yahim, Kampung Harapan, Doyo and Netar using the exploration method and interviewing key informants. For morphological identification using banana descriptor guidelines from the International Plant Genetic Resources Institute (IPGRI). Morphological character data were analyzed in a quantitative descriptive manner using the NTSYs 2.01 application program. The results showed that there were 15 local banana cultivars based on the knowledge of the Sentani people. Based on the phenogram, the local Sentani bananas are grouped into two groups based on the character of the shape, size, color, taste, and color of the organs of the leaves, stems, flowers and fruit. The local banana cultivars have wide phenetic diversity with similarity coefficient values ranging from 20-73%. The closest similarity value is found in Hoyombi and Wabulu cultivars with a similarity value of 73%. The furthest similarity value was found in the Rawo and Anakhola cultivars in group A, and the Olukhu and Honggambu cultivars in group B with a value of 53%. Key words: diversity; characters; morphology; bananas; Sentani.
香蕉植物是一种很有发展前景的食物来源。这是因为香蕉很受所有群体的欢迎，而且在热带地区很容易种植。印度尼西亚有许多野生和栽培香蕉品种，其中一种香蕉生长在Sentani湖周围，这导致了香蕉类型和品种之间的形态特征差异。本研究的目的是根据形态特征确定当地Sentani香蕉的表型多样性。该研究于2022年6月至10月在森塔尼湖周围的五个村庄进行，即Ayapo, Yahim, Kampung Harapan, Doyo和Netar，采用勘探方法并采访了关键线人。利用国际植物遗传资源研究所(IPGRI)的香蕉描述符指南进行形态鉴定。形态学特征数据采用NTSYs 2.01应用程序进行定量描述分析。结果表明，根据森塔尼人的知识，当地有15个香蕉品种。根据物象图，当地的Sentani香蕉根据叶子、茎、花和果实的器官的形状、大小、颜色、味道和颜色的特征分为两类。地方香蕉品种具有广泛的遗传多样性，相似系数在20 ~ 73%之间。相似值最接近的品种是好云比和瓦布鲁，相似值为73%。A组的Rawo和Anakhola品种的相似性值最大，B组的Olukhu和Honggambu品种的相似性值为53%。关键词:多样性;字符;形态;香蕉;Sentani。

The increase in population in recent years has affected the utilization of facilities and infrastructure, including the use of vehicles. For the past 10 years, the population in Papua has increased by around 4.13% per year, resulting in the need for daily mobility to increase. The high mobility demand in Papua could affect the increase in pollution, thus affecting the air quality. Exposure to pollutants in ambient air and environmental noise in the long term will have an impact on human health. Therefore, in this study, we analyze the current conditions of air pollution parameters in several major cities in Papua, such as Jayapura, Merauke, Sentani, and Timika. The method used is a survey. Environmental parameters measured were air content of SO2, NO3, PM 10, PM 2.5, HC, O3, CO, dust, Pb, noise, and The Air Pollutant Standard Index (ISPU) value. Observational data obtained were analyzed and displayed using the ArcGIS program. The parameters for determining the location of sampling points are densely packed highway areas, industrial areas, residential areas, and offices. The results of the study indicated that the ambient air quality in all study sites is below the required quality standard. While the results of environmental noise that exceed the highest quality standards located in specifics area on each study site are as follows, Merauke at PLTD Merauke I PT. PLN Persero with 81.24 dB(A), Sentani at Sentani City Square Roads with 70.2 dB (A), Mimika at Perumahan Pemda SP-2 with 65.30 dB(A), and Sentani at Kantor Bupati Jayapura with 64, 54 dB (A). However, the ISPU value for pollutant substances is still in the range of 0-50, which means that the air quality category is very good to carry any outdoor activities, and does not have any negative impact on humans, animals, or plants.Key words: air quality; noice; ISPU; Papua.
近年来人口的增加影响了设施和基础设施的使用，包括车辆的使用。在过去的10年里，巴布亚的人口以每年约4.13%的速度增长，导致对日常流动性的需求增加。巴布亚的高流动性需求可能会影响污染的增加，从而影响空气质量。长期暴露于环境空气中的污染物和环境噪声中，会对人体健康产生影响。因此，在本研究中，我们分析了巴布亚几个主要城市(如Jayapura, Merauke, Sentani和Timika)的空气污染参数现状。使用的方法是调查。测量的环境参数包括空气中SO2、NO3、pm10、PM 2.5、HC、O3、CO、粉尘、Pb、噪声和空气污染物标准指数(ISPU)值。利用ArcGIS程序对观测数据进行分析和显示。采样点位置的确定参数为密集的高速公路区域、工业区、居民区和办公楼。研究结果表明，所有研究点的环境空气质量均低于规定的质量标准。各研究点特定区域环境噪声超过最高质量标准的结果如下:Merauke在PLTD Merauke I PT. PLN Persero为81.24 dB(A)， Sentani在Sentani City Square Roads为70.2 dB(A)， Mimika在Perumahan Pemda SP-2为65.30 dB(A)， Sentani在Kantor Bupati Jayapura为64,54 dB(A)。然而，污染物的ISPU值仍然在0-50的范围内。这意味着空气质量类别非常好进行任何户外活动，并且不会对人类，动物或植物产生任何负面影响。关键词:空气质量;噪音;ISPU;巴布亚岛。

The waste of sawdust and wood chips in the wood processing industry in Jayapura City has not been utilized properly and maximally, but only as firewood. In fact, this waste has a large enough potential to be developed as a raw material for making charcoal briquettes. This research method analyzed the calorific value of 5 (five) treatments using Completely Randomized Design, using 5 (five) repetitions so that the total treatment was 25 (twenty five). The treatment in this study was T0: 100% sowang wood charcoal, T1: sawdust/merbau wood chips (90%) + 10% tapioca flour, T2 : sawdust/merbau wood chips 70% + sawdust/mixed jungle wood chips 20% + 10% tapioca flour, T3: 45% merbau sawdust/wood chips + 45% mixed jungle sawdust/wood chips + 10% tapioca flour, T4: 20% merbau sawdust/wood chips + sawdust/wood chips mixed jungle 70% + 10% tapioca flour. The results showed that T0: 100% sowang wood charcoal produced the highest calorific value, namely 7,619 cal/gram compared to other treatments. The highest calorific value of charcoal briquettes is the T2 calorific value treatment: 70% merbau sawdust/chip + 20% mixed sawdust/jungle wood chips + 10% tapioca flour, with a calorific value of 6,230 cal/gram and charcoal briquettes when it has been produced regularly commercially, grilled fish traders and satay traders are willing to use charcoal briquettes from wood processing industry waste.

The research was conducted in June to August 2022 in Ubiyau Village, Yanamaa Village and Yuwanain Village, Arso District, Keerom, Papua. The aim of the study was to determine the impact of forest conversion to oil palm plantations on the diversity and abundance of the Superfamily Papilionoidea butterfly. The line transect count method was used for sampling butterflies with a transect length of 1500 m at each study area. Sampling was carried out along a line transect in an imaginary box measuring 10 x 10 x 10 m which was carried out on sunny days from 09.00 am to 14.00 pm. The highest species diversity of the Superfamily Papilionoidea was found in Secondary Forest (HS), namely 70 species consisting of Papilionidae (8 species), Pieridae (5 species), Lycaenidae (21 species) and Nymphalidae (36 species). There were 42 species of butterflies recorded from Non-Productive Oil palm Plantations consisting of Papilionidae (5 species), Pieridae (4 species), Lycaenidae (11 species) and Nymphalidae (22 species). While the lowest number of butterfly species was encountered in Productive Oil Palm Plantations namely 32 species consisting of Papilionidae (5 species), Pieridae (3 species), Lycaenidae (8 species) and Nymphalidae (16 species). These data indicated that conversion of secondary forest to oil palm plantations reduced butterfly species by around 40-53%. The highest Shannon-Wiener Diversity Index (H') and Margalef Diversity Index (Dmg) values were found in secondary forest (H'=3.4; Dmg =13.7) followed by Non-Productive Oil Palm Plantations (H'=2.5; Dmg=7.2) and Productive Oil Palm Plantations (H=2.0; Dmg=6.1). The highest species similarity was between Secondary Forest and Productive Oil Palm Plantations with Sorensen Index value IS=60%, followed by Non-Productive Oil Palm Plantations and Productive Oil Palm Plantations (IS=51%) and the lowest species similarity index was between Secondary Forests and Non-Productive Oil Palm Plantations (IS = 46%). In Secondary Forest the composition of the number of individuals per species tends to be more evenly distributed compared to oil palm plantations. Forest conversion to Oil Palm Plantations has a negative impact on butterfly species diversity of the Superfamily Papilionoidea. The lost species that were not found in oil palm plantations were forest specialist species with small range sizes and niches as well as specific diets that were only found in forest.

The aim of the study was to determine the impact of forest conversion to oil palm plantations on the diversity and abundance of the Superfamily Papilionoidea butterfly. The line transect count method was used for sampling butterflies with a transect length of 1500 m at each study area. Sampling was carried out along a line transect in an imaginary box measuring 10 x 10 x 10 m which was carried out on sunny days from 09.00 am to 14.00 pm. The highest species diversity of the Superfamily Papilionoidea was found in Secondary Forest (HS), namely 70 species consisting of Papilionidae (8 species), Pieridae (5 species), Lycaenidae (21 species) and Nymphalidae (36 species). There were 42 species of butterflies recorded from Non-Productive Oil palm Plantations consisting of Papilionidae (5 species), Pieridae (4 species), Lycaenidae (11 species) and Nymphalidae (22 species). While the lowest number of butterfly species was encountered in Productive Oil Palm Plantations namely 32 species consisting of Papilionidae (5 species), Pieridae (3 species), Lycaenidae (8 species) and Nymphalidae (16 species). These data indicated that conversion of secondary forest to oil palm plantations reduced butterfly species by around 40-53%. The highest Shannon-Wiener Diversity Index (H') and Margalef Diversity Index (Dmg) values were found in secondary forest (H'=3.4; Dmg =13.7) followed by Non-Productive Oil Palm Plantations (H'=2.5; Dmg=7.2) and Productive Oil Palm Plantations (H=2.0; Dmg=6.1). The highest species similarity was between Secondary Forest and Productive Oil Palm Plantations with Sorensen Index value IS=60%, followed by Non-Productive Oil Palm Plantations and Productive Oil Palm Plantations (IS=51%) and the lowest species similarity index was between Secondary Forests and Non-Productive Oil Palm Plantations (IS = 46%). In Secondary Forest the composition of the number of individuals per species tends to be more evenly distributed compared to oil palm plantations. Forest conversion to Oil Palm Plantations has a negative impact on butterfly species diversity of the Superfamily Papilionoidea. The lost species that were not found in oil palm plantations were forest specialist species with small range sizes and niches as well as specific diets that were only found in forest.

Several important chemical components are still present in coffee skin, although they have not yet been put to much use. This study aims to determine the physical and chemical quality as well as the antioxidant activities of cascara tea, which is produced from the skin of Papuan arabica coffee. Coffee skins are gathered by The Highland Roastery Café from several Papuan coffee producers. Cascara is used to make tea, which is packaged in tea bags after being sun-dried. The analysis of physical and chemical quality is in accordance with SNI 3753: 2014. Physical and chemical quality parameters for tea include the condition of the steeping water, moisture content, ash content, crude fiber, phytochemicals, polyphenols, and caffeine levels. It is possible to measure antioxidant activity using the DPPH technique. The physical and chemical characteristics of cascara tea manufactured from Papuan arabica coffee skins are as follows: typical brewing water conditions, moisture content, total ash content, and crude fiber are all 13.00 ± 0.11%, 10.96 ± 0.12%, and 40.55 ± 0.14%, respectively. Phytochemical screening showed that cascara tea contains alkaloids, terpenoids, saponins, and polyphenols, with a total polyphenol content of 1.33 ± 0.05% and caffeine of 0.44 ± 0.05%. Cascara Papua tea exhibits strong levels of antioxidant activity with an IC50 of 13.96 ppm. Therefore, it can be concluded that cascara tea, which is made from arabica coffee skins from Papua and sun-dried, has a physical and chemical quality that complies with the standards. and can be used as an antioxidant beverage to increase endurance. Key words: cascara; coffee skin; arabica coffee; physical and chemical quality; antioxidant.

Gene polymorphism refers to a variation in DNA sequence that occurs in a population with a frequency of 1% or higher. Polymorphism may be a variation in single nucleotide (SNP) or a variation in some repetitive DNA sequences (length polymorphism). Several methods can be used to analyze polymorphism, included Polymerase Chain Reaction (PCR), DNA sequencing from the conventional method to more sophisticated method such as Next Generation Sequencing (NGS), fluorescence in situ hybridization, comparative genomic hybridization, and DNA microarrays. Recently, more studies have been carried out to find the relationship between polymorphism and disease severity or prognosis, response to various drugs, susceptibility to environtmental factors such as toxins, susceptibility to infections and cancers.Key words: DNA; gene polymorphism; PCR; clinic.
