Abstract

Sweet potato is a source of carbohydrates, widely cultivated by the people of Papua. Sweet potato have a variety of different types and characters. This diversity has an important in the process of selecting and assembling new superior varieties. Identification based on morphological characters on leaves and tubers can be used to the similarities and differences in plants, both quantitatively and qualitatively. The sugar level in sweet potato tubers needs to be known, because it is related to use as food for patient with degenerative diseases. The aim of the study was to identify the morphological characters of leaves and tubers, as well as sugar level in three sweet potato accessions cultivated by the local community. Identification of morphological characters of leaves and tubers used descriptive methods, while identification of sugar level used experimental methods. The results showed that (1) the morphological characters of the leaves and tubers of the three types of sweet potato cultivated by the local community were different, both quantitatively and qualitatively. (2) The highest sugar level is found in boiled and baked light yellow sweet potatoes. The lowest sugar level was found in boiled white sweet potatoes (3.570brix) and creamy sweet potatoes that were baked (3.130brix). White and creamy sweet potatoes are more suitable for people with degenerative diseases.

Abstract

This study aims to determine the condition of physical and chemical water quality in the waters of Lake Sentani, Waibu District, Jayapura Regency. The method used in this study is a normative survey method, which is a method used to observe certain objects or conditions, which are nothing but intended to make systematic descriptions, pictures or drawings, of data or facts and characteristics in relation to the information provided. obtained by setting in a certain standard or norm. Data collected, processed and presented descriptively. The results showed that physical water quality parameters, water temperature ranged from 28.4 – 30.2 to 30.3 oC, turbidity 4.10 – 4.20 to 4.90 NTU, TDS ranged from 119.0 – 129.0 up to 132.0 mg/l and TSS ranged from 82.0 – 82.0- to 96.0 mg/L and non-metallic inorganic chemical water quality parameters, the degree of acidity (pH) ranged from 7.53 – 7.55 to 7.81mg/l, dissolved oxygen (DO) ranged from 6.02 – 6.10 to 6.50 mg/L, biochemical oxygen demand (BOD) ranged from 1.72 – 2.64 to 2.90 mg/L , nitrite (NO2-N) ranged from 0.004 – 0.004 to 0.004 mg/L and phosphate (PO4-P) ranged from 0.53 – 0.97 to 1.02 mg/L. From the results of this study it can be concluded that the physical quality and the water chemistry of Sentani Lake waters at the study site is still in the optimal range or suitable for aquaculture activities in Sentani Lake waters.

Abstract

Cocoa is a type of plantation plant that is very popular with preparations the fruit, chocolate is processed derived from cocoa beans. In Jayapura Regency, there is a household industry, the Kenambai Umbai Chocolate House, which processes fermented cocoa beans from farmers in the Nimbokran District, Jayapura Regency. The purpose of this study was to determine differences in fat content in chocolate bar products from the household industry, Kenambai Umbai Chocolate House, Jayapura Regency, and commercial chocolate products. The implementation of the fat content test was carried out at the Chemistry Education Laboratory, Cenderawasih University, Jayapura. The method used for the fat content in chocolate bars is a qualitative method because the analysis was carried out in the laboratory using the Soxhlet method. The fat content of chocolate at Kenambai Umbai Chocolate House after being tested for fat content using the Soxhlet method, in one package of chocolate with a net weight of 100 grams contains 21.4% total fat. Meanwhile, the SNI (Indonesian National Standard) for total fat in chocolate bars is > 31%. So it can be concluded that the fat content in chocolate products Kenambai Umbai Chocolate House does not meet SNI.

Abstract

This research aims to find out the appearance of production of the beef cattle business farming by partnersip system namely gaduhan system in 2019 in Arso District, Keerom, Papua. A survey was conducted on all domestic cattle breeders as many as 40 breeders that lasted from April to May 2021. The initial weight of the cattle was 115.19 kg and the average final weight of the cattle was 229.55 kg, so the average weight gain of domestic cattle of gaduhan system kept by as many as 40 breeders in Arso District, Keerom Regency is about 114.36 kg during the rearing period of approximately 360 days so that the average weight gain of cattle per day is 0.32 kg. The daily weight gain of domestic cattle of gaduhan system kept by breeders is quite high. The conclusion obtained is that the performance of domestic cattle production of gaduhan system in Arso District, Keerom Regency, aid package in 2019 is quite good.

Abstract

Asmat Regency has a mangrove forest area of 300,000 hectares. It has dozens of big and small rivers that empty into the Arafura Sea. The soil structure is muddy along the coast, so mangrove plants thrive in this environment far downstream. Based on these conditions, it is necessary to conduct research to determine the types of mangroves that live in the coastal area of Kampung Aou, Pulau Tiga District, and Asmat Regency. The aims of this study were to determine the types of mangroves that live in the coastal area of Kampung Aou, Pulau Tiga District, Asmat Regency, South Papua Province, and the condition of the water quality at the study site. This research lasted for 2 months, from January to February 2023, and was located in the coastal area of Aou Village, Pulau Tiga District, Asmat Regency, South Papua Province. The method used in this research is the survey method. Based on the results of the research, overall, it was found that 10 types of mangroves were grouped into 5 orders, 5 families, 8 genera, and 10 species. The water quality values are still in the normal range for mangrove life, namely: pH 7, temperature 28 °C–29 °C, and salinity ranges from 13–14%.

Abstract

Masculinization is an attempt to increase the number of male fish or direct fish to become male. This is because reproduction energy is diverted to somatic growth. Monosex production of males using the hormone metyltestosterone is reported to be most effective using the larval immersion method during the sex differentation or critical period, in which the larval brain is still a biopotential state directing the formation of sexes in morphology, behaviour and function. Immersion is one of the methods used for male sex change apart from oral (feeding) and injection. Soaking the tilapia larval stage at the age of 10 and 14 days with 1,800 ug/LMT for 4 and 8 hours produced 91,6% and 98,3% of males. The study aimed to determine how long soaking of the larvae in the hormone methyltestosterone on the good masculinization of tilapia (Oreocrhomis niloticus) and what percentage of masculinization is in the larvae of tilapia (Oreocrhomis niloticus) using the hormone methyltestosterone through immersion.The result of ANOVA calculation show that the difference in the duration of immersion with the hormone methyltestosterone sygnificantly affect the percentage of the number of male fish produced.
