Objective: This paper investigates the effect of carrageenan from various harvest times on fishball characteristics. The harvest time consists of three different periods (40 days, 45 days, and 50 days) from Bontang Coastal, East Kalimantan, Indonesia. Methods: The carrageenan fortified to fishball used two concentrations that were 0.25% and 0.5%.The proximate analysis, including moisture, ash, protein, fat, and carbohydrate, showed significantly different (p < 0.05). The texture analysis showed that there was significantly different (p > 0.05). Results: The fishball adding carrageenan from different harvest time of seaweed also had a significantly different of sulfate content and crude fiber content (p < 0.05). The lowest water activity obtained on the fishballs adding 0.25% carrageenan from 50 days ages harvested. Conclusions: In this research, the fishball adding 0.25 carrageenan from 50 days ages was the best treatments based on the highest of protein content and the lowest of water activity.

This research in coastal area of Dumai has been completed in September untill Desember 2003. The aim of this research was to collect basic data of mangrove ecosystem which covered inventory of biodiversity and ecology structure by using primary and secondary data. Primary data of mangrove forest ecosystem has been collected by line transect method while secondary data was collected by study literature and previous study report. The result showed that there were 17 types of primary mangrove and 18 types of secondary mangrove. The main value indeks in every study area indicated that in the study area I and IV, Xylocarpus granatum had high value as 104,53 and 104,22 subsequently. In the study area II, III and V, Rhizophora apiculata had the high value which subsequently were 114,39, 108,81 and 110,19. There were two main extinct spesies of mangrove, which are Scyphiphora hydrophyllaceae (Cingam/Perepat Lanang) and Sonneratia ovata (Kedabu), in which exceptional management is needed for sustainability of these species.

<em>Kepahiang Robusta coffee has received a Geographical Indication (GI) certificate. Maintaining the quality of green coffee bean has been achieved  through the application of proper harvesting technology. This study aimed to evaluate the effect of fruit maturity level when harvested on yield losses due to coffee berry borer (CBB) and the quality of green coffee bean. The research was conducted from December 2019 to August 2020 in Bukit Sari Village, Kabawetan District, Kepahiang Regency, Bengkulu Province. The harvested beans were categorized into 3 groups based on their maturity level, namely: red (K1), reddish yellow (K2), and yellowish green (K3). The parameters observed were the CBB infecteds, yield, physical quality of green coffee bean and chemical content. The results showed that the highest attack rate of CBB found in the red berry about 34.33%, whereas  the highest rendement was 20.52% found in yellowish-green berry. The highest percentage of yield loss due to CBB attacks occurred in red berry at 30.23%. However, the best physical quality and chemical content was also found in the red berry.</em>

This article is a result of research that aims to determine the correlation between students' geometry learning outcomes with analytical ability in the eyes of analytic geometry. This research is a correlational research. the study was conducted at STKIP PGRI Pacitan, where the population is a mathematics education students who is taking analytical geometry courses. Data were taken from 21 students, with test technique, documentation and interview. Data analysis was done by using simple linear regression analysis concept and its calculation using SPSS 16. Based on data analysis, it was found that the result of geometry of field study had positive correlation with students' analytical thinking ability. The relationship falls into the medium category, and the learning outcomes have a predictor contribution to students' analytical ability of 22.5%.

The Remote Sensing Application Center – LAPAN has resulted in information on hotspot spreading. Availability of information monitoring the distribution of hotspots latest rapid, precise and accurate can improve the remote sensing application to support the management of forest resources and establish a monitoring system that is accountable and can be a reference in the organization of activities of forest fire control and land at the same time participate in managing, maintaining safety as well as the preservation of Indonesia’s natural resources is sustainable. Given the importance of information and communication in disaster crisis management, efforts to facilitate the implementation of dissemination of hotspots distribution information to the wider community should properly be realized. One application is to develop a Web-based dissemination system Geographic Information System with Geonode application. The method used in this research is a prototype with open technology. Geonode can integrate that information to the layers with web mapping systems and the internet. The opensource geoportal system is built, the result of a combination of Django framework and Python programming language that is capable of providing dynamic spatial visualization interactively and connected to other electronic information networks. This Dissemination System can be used for decision makers in preparation of planning, development, monitoring, and response to an emergency disaster of forest and land fires in Indonesia, as well as a reference in the field of innovative technology and application of Geospatial information.Keyword: hotspots, forest fires, emergency response, Geonode, dissemination, web applications  ABSTRAKPusat Pemanfaatan Pengideraan Jauh-LAPAN telah menghasilkan informasi sebaran titik panas. Ketersediaan informasi pemantauan sebaran titik panas terkini yang cepat, tepat dan akurat dapat meningkatkan pemanfaatan penginderaan jauh untuk mendukung pengelolaan sumber daya kehutanan dan membangun sistem pemantauan yang akuntabel dan dapat menjadi acuan dalam penyelenggaraan kegiatan pengendalian kebakaran hutan dan lahan sekaligus ikut serta dalam pengelolaan, menjaga keselamatan serta kelestarian sumber daya alam Indonesia yang berkelanjutan. Mengingat pentingnya informasi dan komunikasi dalam penanggulangan krisis akibat  bencana, maka upaya memudahkan pelaksanaan penyebarluasan informasi sebaran titik panas masyarakat luas dengan baik perlu diwujudkan. Salah satu pengaplikasiannya adalah dengan mengembangkan sistem diseminasi berbasis Web Sistem Informasi Geografis dengan aplikasi Geonode. Metode yang digunakan dalam penelitian ini adalah purwarupa dengan teknologi terbuka. Geonode dapat mengintegrasikan informasi tersebut dalam layer-layer sistem pemetaan web dan internet. Geonode merupakan sebuah sistem geoportal opensource gabungan antaran framework Django dan bahasa pemograman Python yang mampu menyajikan visualisasi spasial dinamis secara interaktif dan terhubung ke jaringan informasi elektronik lainnya. Sistem diseminasi ini dapat dipakai untuk pengambilan keputusan dalam persiapan perencanaan, pembangunan, pengawasan, dan respon terhadap keadaan darurat bencana kebakaran hutan dan lahan di Indonesia, serta sebagai referensi dibidang teknologi inovatif dan penerapan informasi Geopasial.Kata kunci: titik panas, kebakaran hutan, tanggap darurat, Geonode, diseminasi, aplikasi web
