Fish smoking is a popular method of fish preservation which extends the shelf life of fish and diversify the range of processed fish products. Smoked tuna is a special dish from Malalanda Village, North Buton Regency that is processed using traditional smoking method using simple equipment. This research was conducted to identify the organoleptic characteristics, referring to the acceptability of a product based on the sensory properties, of smoked tuna produced by local artisans using the traditional smoking method in Malalanda Village, Kulisusu District, North Buton Regency. On-site observation involving randomly-sampled smoked fish artisans was performed. Three tuna fish were obtained from three artisans to undergo organoleptic tests to assess their color, aroma, presentation, and taste. Each sample was assigned a code: Craftsman 1 (T1), Craftsman 2 (T2), and Craftsman 3 (T3). The organoleptic testing involved 37 panelists, consisting of students from the Department of Agricultural Technology at Universitas Sulawesi Tenggara. The ANOVA test revealed that the three types of smoked tuna samples exhibited similar characteristics in terms of color, aroma, presentation, and taste. Specifically, the color characteristics of T1 were rated at 4.27 (liked), T2 at 4.30 (liked), and T3 at 4.30 (liked). The aroma scored T1 = 4.35 (liked), T2 = 4.30 (liked), and T3 = 4.27 (liked), while the presentation showed T1 = 4.30 (liked), T2 = 4.30 (liked), and T3 = 4.27 (liked). Furthermore, the taste was rated T1 = 4.49 (liked), T2 = 4.46 (liked), and T3 = 4.46 (liked). Therefore, no significant differences were found in the organoleptic characteristics of color, aroma, presentation, and taste among the three smoked tuna samples.Keywords:Smoked tuna, organoleptic characteristics, traditional fish smoking process

This study aims to describe the application of social entrepreneurship elements and describe the canvas business model for social entrepreneurship development in the Nata de Coco Sejahtera Mandiri business group. This research was conducted for 1 month (July-August 2022). This type of research is descriptive qualitative using the case study method. The data used are primary data and secondary data obtained through observation, in-depth interviews and documentation. For the first objective, the data was analyzed using the Miles and Huberman data analysis model and for the second objective it was analyzed descriptively qualitatively, then an assessment of the social benefits of the program was carried out using the Social Return of Investment (SRoI) method. The results of this study indicate that the elements of social entrepreneurship have been implemented by the Nata de Coco Sejahtera Mandiri business group in the form of social values, civil society, innovation and economic activity, but have not optimally provided benefits. Nine elements in the business model canvas for social entrepreneurship development have been implemented consisting of customer segmentation, value proposition and social value, channels, customer relationships, revenue streams and community reinvestment, key activities, key resources, key partners, and cost structure, but not yet optimal. Based on the SRoI assessment of the Nata de Coco Sejahtera Mandiri business group, it can be concluded that the benefits generated are 1:0.03, meaning that social entrepreneurship activities have not been able to create sustainability benefits for stakeholders and have not been able to create social business independence, because the resulting SRoI ratio is less than 1 (1). We recommend that the Nata de Coco Sejahtera Mandiri business group optimize the management of environmental aspects by managing liquid waste from the production of Nata de Coco produced, increasing the participation of local residents and increasing the scale of social business.Keywords : Social Entrepreneurship, Nata de Coco, SRoI
本研究旨在描述社会企业家精神要素在Nata de Coco Sejahtera Mandiri商业集团中的应用，并描述社会企业家精神发展的画布商业模式。本研究为期1个月(2022年7月- 8月)。这种类型的研究是使用案例研究方法的描述性定性研究。所使用的数据是通过观察、深入访谈和文献资料获得的一手数据和二手数据。对于第一个目标，使用Miles和Huberman数据分析模型对数据进行分析，对于第二个目标，使用描述性定性分析，然后使用社会投资回报率(SRoI)方法对该计划的社会效益进行评估。本研究的结果表明，Nata de Coco Sejahtera Mandiri商业集团以社会价值观、公民社会、创新和经济活动的形式实施了社会企业家精神的要素，但并未提供最佳效益。社会企业家发展的商业模式画布中的九个要素已经实现，包括客户细分、价值主张和社会价值、渠道、客户关系、收入流和社区再投资、关键活动、关键资源、关键合作伙伴和成本结构，但尚未达到最佳状态。根据Nata de Coco Sejahtera Mandiri商业集团的SRoI评估，可以得出的结论是，产生的效益为1:0.03，这意味着社会创业活动无法为利益相关者创造可持续性效益，也无法创造社会企业独立性。因为所得的SRoI比小于1(1)。我们建议Nata de Coco Sejahtera Mandiri商业集团通过管理Nata de Coco生产过程中产生的废液来优化环境方面的管理，增加当地居民的参与，增加社会企业的规模。关键词:社会企业家精神，Nata de Coco, SRoI

The potential of purple yam (Dioscorea alata L.) as a source of natural antioxidants has not been optimally utilized by the community. So there is a need for innovation in the utilization of purple yam through food diversification. Sago starch has amylose and amylopectin content similar to tapioca. So that in this study we wanted to develop boba with the basic ingredients of sago starch and the addition of purple yam. This study aims to produce boba that has antioxidant activity and is liked by panelists from variations in purple yam preparation and the use of sago starch on physical, chemical properties and preference level. This study used two preparation methods, namely steaming and boiling with variations in the concentration of sago and purple yam puree 48g:12g, 42g:18g and 36g:24g. Bubble pearl was tested for color, moisture content, antioxidant activity, anthocyanin content, liking test and selected samples were tested for total phenol content and ash content. The experimental design used was a complete randomized design with 2 factorials and the data were statistically tested using Univariate Analysis of Variance and ANOVA, if there was a significant difference, followed by DMRT test with α=0,05. The results showed that the preparation method and concentration of sago starch and purple yam puree had a significant effect on the increase in antioxidant activity and anthocyanin content. The selected boba that was favored by panelists was boba with steaming treatment with a concentration of sago starch and purple yam puree of 34g:24g with a moisture content of 67,12% bb, antioxidant activity of 59,54% RSA, anthocyanin content of 8,45 mg/g bk, total phenols of 30,46 mg GAE/g bk, and ash content of 0,02% bk.  Keywords : purple yam puree, antioxidant, bobaÂ

Penelitian ini bertujuan untuk mengtahui evektifitas pengobatan prolonged oestrus dengan menggunakan human chorionic gonadotropin (hCG) berdasarkan pengamatan dinamika ovarium dengan metode ultrasonografi (USG). Empat ekor sapi induk Simmental Crossbreed dilakukan pengamatan pada siklus estrus pertama dan siklus estrus selanjutnya. Siklus estrus pertama (n=4) natural tanpa hCG (-hCG), dan siklus estrus kedua (n=4) diterapi dengan hCG (+hCG) secara intravena. Hasil pengamatan terhadap sapi prolonged oestrus memperlihatkan 3 gelombang folikel dalam satu siklus estrus. Hasil analisis statistik menunjukan perbedaan nyata (P0,05) terhadap waktu ovulasi. Rataan waktu ovulasi pada sapi (-hCG) dan dengan (+hCG) masing- masing adalah 54±12 jam dan 24±0 jam. Tetapi tidak memperlihatkan perbedaan yang nyata (P0,05) terhadap ukuran folikel ovulasi. Rataan ukuran folikel preovulasi pada sapi (-hCG) dan dengan (+hCG) masing- masing adalah 1.57±0.09 jam dan 24±0 jam. Dapat disimpulkan bahwa penyuntikan hCG dapat mempercepat waktu ovulasi namun tidak mempengaruhi ukuran folikel preovulasi.Kata Kunci: Dinamika Ovarium, hCG, Waktu Ovulasi, Simmental Crossbreed.

Land evaluation is the process of assessing the appearance of land for a specific purpose, including conducting and interpreting surveys and studies of land forms, soils, vegetation, climate, and other land aspects in order to identify and make comparisons of various land uses that might be developed. The aims of this study were: to determine land suitability classes and their management for cassava in the Gufasa watershed of Dodinga Village, South Jailolo District, West Halmahera Regency. This research took place from October to November 2021. Evaluation of land suitability refers to the FAO land suitability classification system (1976) to the category of land suitability units. There are two land suitability conditions presented, namely actual land suitability (A) and potential suitability (P). The actual land suitability for cassava plants in the Gufasa Watershed of Dodinga Village is suitable (S) with an area of 496.6 Ha (35.21%) and not suitable (N) with an area of 913.6 Ha (64.78%) with limiting factors, namely very obstructed drainage, flooding heavy (flood hazard), rough texture, heavy erosion and slopes 15%. Suitable land (S) is divided into two classes, namely quite suitable (S2) with an area of 108.0 Ha (7.6%) with a limiting factor of rainfall, rather fine texture, low total N, and mild erosion and marginally suitable (S3) with an area 388.6 Ha (27.55%) with a very low limiting factor of N-total and slope. Potential land suitability for cassava plants if efforts to improve the land limiting factors are obtained that are suitable (S) of 360.8 Ha (28.31%) and unsuitable (N) of 913.6 Ha (7.15%).Keywords: Land suitability, land characteristics, soil quality, limiting factors
